Your recent opinion article was on point; I have been commenting for years that industry and universities need to be working
together to educate the new crop of students about the myriad of opportunities in the electric and utility industry.
No longer is our industry one of stodginess and simple E=IR knowledge. We need skills in many areas going forward. Smart grids,
data analysis and electronic relays open the door for multiple skills. Industry and universities should begin strategizing on work
force requirements. When I graduated in the late ‘60s, many universities had strong programs related to the power industry. Many
of those have faded away, and a new set of programs should be developed.

Letter to Editor:
I read with interest your opinion piece in the December 2014 issue of Power Engineering.
Here in Nova Scotia, we also see a problem with the supply of Power Engineers (stationary engineers). This affects the operation of power plants, hospitals, and manufacturing
firms, as under law, we need qualified Power Engineers to operate these facilities. You need
a “ticket” to perform these functions.
As people retire, there are less and less qualified personnel to fill the positions.
Add to that, there is a lot of work required to study and pass the examinations that are
mandatory to rise to a First Class Power Engineer.
I was president of Engineers Nova Scotia, the licensing body for professional engineers
back in 2008. At a seminar, the looming skills deficit was discussed even back then. I sat in on
a discussion that related to the 2006 census information here in Canada.
As the baby boomer people in the age group 55-70 started retiring in droves, we found
that the equivalent population in the 20-35 year bracket only accounted for about 50 percent
of the older bracket. So even if we employed all the young people, we’d still be short on total
numbers.
Before coming to work here for CBCL Limited, I was a plant engineering person for Michelin
Tires for 28 years.
Even companies like Michelin are now struggling to replace retiring employees.
One of Michelin’s biggest success stories here in Nova Scotia was that people came and stayed for 30 years. Now one of its biggest
challenges is that people came and stayed for 30 years; and now they want to retire. When your turnover rate jumps from 1 percent
to maybe 12 percent in just a few years (due to retirements), how do you easily handle that?
And passing on 30 years of knowledge to a newly hired person just can’t happen overnight.

OPINION
Solar Inequity
BY RUSSELL RAY, CHIEF EDITOR
S
olar power accounted for more
than a third of new generation
built in the U.S. during the first
nine months of 2014. What’s more, the
U.S. installed more than 1,300 MW of
solar photovoltaic (PV) capacity in the
third quarter, up 41 percent compared
with the same quarter in 2013, making
it the second largest quarter for solar installations in the history of this emerging market.
In just five years, U.S.
solar capacity has grown
a whopping 993 percent to 17,500 MW. The
growth stems from subsidies for rooftop solar
panels and net metering
programs that require
utilities to purchase the
excess power produced
by homes and businesses
at a set retail rate.
Although this formula
has been very effective, it
is not sustainable at the
pace the industry is growing and should
be reconstructed to reflect the realities of
maintaining and upgrading a grid used
by rank-and-file citizens. The breakneck
growth of solar PV is pinching the bottom lines of utilities in state after state.
Battles between utilities and the manufacturers of solar panels have erupted
in several states, where utilities have requested permission to charge customers
who generate their own power monthly
fees to pay for the maintenance and upkeep of a distribution and generation system that everyone still relies on.
The rules for net metering programs
and solar incentives should be revisited
and reassessed due to vastly different
4
circumstances caused by this solar revolution. Net metering programs were
never meant to be permanent. Regulators have a responsibility to consider
the rapid growth of distributed solar
and the subsequent cost to utilities
and their customers.
The growth of distributed solar,
spawned by years of generous incentives,
is affecting utilities’ ability to pay for the
up-keep of distribution and generation
assets because the cost of operating and
maintaining the infrastructure is not collected from customers participating in
net metering programs.
Just last month, House and Senate lawmakers in Virginia voted to repeal that
state’s standard for renewable generation,
which required utilities to get 25 percent of their generation from renewable
resources by 2025. In Oklahoma, Gov.
Mary Fallin enacted a law enabling utilities, upon approval of state regulators,
to charge customers who have installed
solar panels on their home a monthly
fee. In addition, Oklahoma, Kansas and
Ohio may alter their standards for the
amount of renewable generation a utility is required to provide customers.
The battle over solar incentives, renewable standards and net metering
programs is sure to escalate this year.
A well-funded campaign against the
policies that have fueled the breakneck
penetration of solar power is being
waged by utilities and their supporters.
The consequences of these battles
will be significant for both
sides. For the solar industry, sales could plunge if
the payments consumers
receive from utilities are
eliminated or fall to a level
that doesn’t justify the cost
of installation. For utilities, revenues will continue
to fall and consumer rates
could skyrocket if they are
unable to convince state
regulators to create a system that accounts for these
disruptive forces.
The current net metering
structure creates a financial burden for
customers who can’t afford to install
expensive solar panels on their homes.
For those customers, the cost of electricity will get more expensive as they
pay a larger share of the cost to operate
and maintain the nation’s grid.
With 578,000 individual solar installations in the U.S., solar accounts
for 17,500 MW of capacity, less than 2
percent of the nation’s total capacity.
The debate over solar is about creating a just cost structure that is fair to
both sides. This fight is expected to
take place in more than two dozen
states. The path to common ground
will surely be turbulent.

Dominion Virginia Power said it filed
an application with state regulators to
build the state’s first large-scale solar project.
The filing outlines plans for a 20-MW
solar array on 125 acres near the Remington Power Station in Fauquier County.
The power project would contain approximately 90,000 photovoltaic panels. At peak capacity, it would generate
enough power for 5,000 homes. Its estimated in-service date is October 2016.
In a statement, Gov. Terry McAuliffe
said the project would nearly double Virginia’s production of solar energy.
Alabama carbon capture
pilot project begins testing
The National Carbon Capture Center (NCCC) began pilot-scale testing of
a cost-effective advanced technology for
capturing carbon dioxide (CO2) from
flue gas in Wilsonville, Alabama.
Under an agreement with the National Energy Technology Laboratory,
Linde LLC is operating a 1-MW pilot
project that is expected to capture 30
tons of CO2 per day. The project will utilize Linde-BASF CO2-capture technology
on coal-derived flue gas. The technology will absorb CO2 from the flue gas
at a low temperature in the absorption
column; the solvent will then transfer to
a stripping column where steam is added
to heat the solvent, reversing the chemical reaction and releasing high-purity
CO2 for compression and pipeline transport.
The NCCC’s testing facility also
includes a post-combustion carboncapture facility from Alabama Power’s
Gaston plant Unit 5, an 880-MW pulverized coal unit.

ENERGY MATTERS
Slogging Through a
Million-Plus Comments
BY ROBYNN ANDRACSEK, P.E., BURNS & MCDONNELL AND CONTRIBUTING EDITOR
T
he comment period on the
controversial Clean Power
Plan (CPP) ended Dec. 1,
2014. EPA received more than 1.5 million comments on docket # EPA-HQOAR-2013-0602-0001. What insights
are contained within? Is each comment
a unique thought on the rule? Will EPA
make substantial changes to the proposed rule?
From ordinary citizens to executives
of major think tanks, the comments
represent a wide range of sources. They
include detailed technical critiques,
generic statements of opposition and
support, and succinct counterclaims
full of legalese.
“Renewable energy, along with the
associated environmental attributes, is
regularly sold across state boundaries…
The lack of clarity around interstate
crediting is creating uncertainty for buyers of renewable energy and is already
impeding the development of projects
that will send power across state lines,”
said Malcolm Woolf, senior vice president of Policy and Governmental Affairs for Advanced Energy Economy, a
national trade association for advanced
energy technologies.
David Doniger, director of the Climate and Clean Air Program at the
National Resources Defense Council
(NRDC), said the CPP should contain
stronger provisions.
“NRDC has presented a number of
ways to improve and strengthen the
CPP and with just three of these major
recommendations: 1) updated baseline and cost and performance data, 2)
implementation of the noticed formula
change to properly account for energy
10
efficiency and renewables, and 3) adoption of a minimum transition from
older steam generation to new natural
gas combined cycle units, we find that
EPA can significantly strengthen the
proposal at reasonable cost,” said David
Doniger, Director, Climate and Clean
Air Program. Natural Resources Defense Council.
The Bipartisan Policy Center has even
conveniently organized all comments
from state and federal officials:
• “The proposed rule places a higher
burden on some state to achieve
the required reduction vis a vis other states,” said Clifford Wilson III,
Interim Secretary, Florida Department of Environmental Protection.
• “Idaho believes that the EPA lacks
the legal jurisdiction to regulate
carbon emissions in the overly
broad fashion it is proposing,” said
C.L. “Butch” Otter, Governor of
Idaho.
• “When EPA designs its program for
regulation of existing generating
plants, it should also allow states
and utilities to take credit for already implemented actions that
have increased the use of proven,
cost-effective energy efficiency, reduced the carbon intensity of the
state’s generation fleet, and reduced
CO2 emissions,” said Elizabeth Jacobs, chair, Iowa Utilities Board.
Significant legal issues have been
raised, one of which concerns EPA’s
authority to regulate CO2 emissions
from existing power plants under the
CPP when mercury is already regulated
under the Mercury and Air Toxics Standards (MATS). This legal conundrum
was succinctly explained in comments
by Laurence Tribe, professor of constitutional law at Harvard Law School, and
Peabody Energy Corporation:1
“On its face, the Proposed Rule violates Section 111 of the Clean Air Act,
42 U.S.C. §7411, because the statute
expressly forbids the regulation of any
air pollutant emitted from a source category that EPA already regulates under
Section 112 of the Clean Air Act, 42
U.S.C. §7412…Stationary power plants
are already a source category regulated
under Section 112 of the CAA. EPA
categorized power plants as part of a
“source category” under Section 112 in
2000. In February 2012, EPA promulgated a new national emission standard for power plants under Section
112. Earlier this year, the D.C. Circuit
upheld EPA’s rule under Section 112.
Accordingly, the plain text of Section
111(d) flatly and unambiguously prohibits the Proposed Rule. As the Supreme Court opined in Am. Elec. Power Co. v. Connecticut: “EPA may not
employ § 7411(d) if existing stationary
sources of the pollutant in question are
regulated under the national ambient
air quality standard program, §§ 74087410, or the ‘hazardous air pollutants’
program, § 7412.”
EPA had a legal deadline of Jan. 8,
2015 to finish the regulation. However,
EPA must first submit the rule to the
White House Office of Management
and Budget (OMB) for review, a process
that normally takes 30 to 90 days.
This one regulation will shape the
future of energy policy in the U.S. Lawsuits, delays, and confusion are inevitable.

VIEW ON RENEWABLES
Mexico’s Ready to
Do Business in the
Wind Sector
BY SHARRYN DOTSON, ASSOCIATE EDITOR
T
he Mexican government announced in late 2014 that it
is going to implement a new
energy policy that would open up
the electricity market for oil and gas.
However, the benefts of the new policy have trickled down to renewables,
most notably wind power.
The policy liberalizes all of the energy sectors and ends state-owned
power utility Federal Electricity Commission’s (CFE) monopoly on power
generation and trading. The Mexican government is aiming to create a
wholesale electricity market with the
decision. According to statistics from
the U.S. Commercial Service (USCS),
installed wind power capacity in Mexico is projected to double by 2026 with
an emphasis on clean energy and natural gas.
Under the new policy, the Mexican
government has a 12-year goal for renewable energy production, and plans
were just announced for an additional
6.5 GW of installed wind capacity by
2018, totaling about 9 GW of capacity
and $14 billion in investments. Mexico
currently has 2.6 GW of wind capacity
installed from 31 wind farms in operation.
The Mexican Wind Energy Association said it expects 15 GW of wind capacity online between 2020 and 2022, and
wind could potentially provide 8 to 12
percent of the world’s electricity by 2020.
International companies have taken
note and are jumping in head frst to
do business. Iberdrola said it plans
to spend up to $5 billion in renewable and natural gas projects; Gamesa
wants to spend more than a billion
www.power-eng.com
dollars on new wind projects, supplier
development and a service center; and
Acciona says it will build three wind
farms with a potential capacity of
2,000 MW a year for $650 million.
Enrique Ochoa Reza, director of
CFE, said on Fox News Mexico has to
create a diverse energy mix in to increase energy security.
“We need to use wind, water, the
sun and geothermal energy to generate
electricity,” Ochoa Reza said. “Mexico
has a big potential in renewable energy
and its climate and geographical location make it a privileged country.”
According to the U.S. Energy Information Administration, Mexico is
a hotbed of wind development. The
Oaxaca I wind project recently came
online in 2014 and was followed by the
completion of La Venta III this year.
Those projects join the Oaxaca II, III
and IV wind projects that came online
in the frst half of 2012. The Mexican
unit of EDF completed the 164-MW Bii
Stinu Wind Project in 2014. Gamesa
in October turned over ownership of
a 74-MW wind plant to Grupo Mexico.
In Baja, the electricity from Sempra
International’s 156-MW Energía Sierra
Juarez (ESJ) wind development will be
exported to the U.S. over a new transmission line, EIA said. The 156-MW
frst phase of ESJ was scheduled for
completion in 2014. ESJ’s long-term
development plan includes additional
phases, with a potential total capacity
of more than 1.2 GW.
The development of wind energy, like
many other generating sources, is dependent on fnancial backing. The ExportImport Bank of the United States has
authorized $462 million to support U.S.
exports related to power generation projects, including $198 million to support
U.S. exports in renewable energy, according to the bank’s 2014 annual report.
The U.S. Department of Energy recently issued a presidential permit to a subsidiary of Sempra International for construction, operation, maintenance, and
connection of a 230,000-volt transmission line across the U.S.-Mexico border.
When completed, the transmission line
will supply electricity from a Mexican
wind farm to the California market. It
looks like Mexico’s probable wind boom
will help the U.S. as well!
Not only will a boost in Mexican
wind help the U.S. grid, it will beneft
U.S. manufacturers. The USCS said U.S.
equipment is considered top notch for
Mexican power generation projects.
“U.S. technology is highly valued as it
represents high quality and compliance
with the standards,” said Claudia Salgado, a commercial specialist with the
USCS. “The price is also important in
the Mexican market, and this is the reason why competition from other countries, especially Europe and Asia, is very
strong.”
Mexico is well known for its oil and
gas production, but wind and solar are
quickly climbing the ranks of installed
generating capacity in the country.
Now with the opening of the energy
market, wind installations are expected
to drastically increase within the next
decade.
While that means big business for
Mexico, even U.S. companies can fnd
some beneft to the change in the policy,
and that is good news for everyone.

GAS GENERATION
A Short History
of the Evolving Uses
of Natural Gas
BY TIM MISER, ASSOCIATE EDITOR
L
ike most people in the power
industry, we editors at Power Engineering magazine spend a lot
of time looking forward. It’s required if
we are to stay ahead of new projects and
emerging technologies (never mind editorial deadlines).
Now and then, though, it’s instructive
to look back on the industry in an attempt to maintain a sense of perspective.
A magazine like Power Engineering, which
has been in continuous publication since
the late 1800s, has an interesting history
on its own. Both Thomas Edison and
Nikola Tesla published within these covers. Perhaps as interesting, though, is the
history of natural gas generation itself.
Long before its use in power generation, natural gas had already demonstrated its utility. Its presence was known in
ancient times. Some scholars have speculated that the Oracle at Delphi, located on
Mount Parnassus in Greece circa 1000
B.C., owed its mystical reputation to natural gas that seeped through the rocks,
mentally affecting the Pythia and her
devotees, who used it as a kind of gateway
to altered consciousness. Natural gas was
also used more deliberately. As early as
500 or 600 B.C., the Chinese were transporting natural gas through bamboo
pipelines, burning it to desalinate sea water and render it drinkable. By 100 A.D.,
the Persians of modern-day Iran were
using natural gas in their homes. Many
centuries later in 1626, French explorers
observed Native Americans in New York
deliberately igniting natural gas seeps
around Lake Erie.
The first commercial use of natural gas
occurred in England, where in 1785 it
was produced from coal and used to light
12
houses and streets. Three decades later in
1816, the residents of Baltimore, Maryland did the same, becoming the first
city in the United States to harness the resource to illuminate their thoroughfares.
While in its early incarnation natural
gas was used almost exclusively for light,
in 1885 Robert Bunsen (of Bunsen burner renown) pioneered new ways to utilize
the thermal properties of natural gas. In
1904 natural gas was first used to provide
central heating and large-scale hot water
supplies in London. Once natural gas was
in common employ heating water, it was
not so great a leap to use it beneath boilers in the creation of steam for industrial
purposes. This paved the way for the use
of natural gas in the generation of electricity, and so evolved an industry that today heats oceans of bath water and acres
of casseroles, all while lighting our cities
and powering the information age.
Electricity generated using natural gas
turbines was first produced for public
use in 1939/1940 at a plant in Neuchâtel, Switzerland. The total output of the
turbine was 4 megawatts (MW). Before
this in 1937, Sun Oil had used a gas turbine to generate air and electricity for
private use at its chemical plant in Philadelphia. In 1945, a two-shaft reheat gas
turbine achieved a world record 10 MW
output, followed in 1948 by a combined
total output of 40 MW generated at the
world’s largest gas plant in Beznau, Switzerland. Clearly, Switzerland was a busy
place for emerging natural gas technologies in the 1940s.
In 1960, North America claimed its
piece of the pie when a power plant in
Port Mann, British Columbia became the
largest gas plant in the world, operating
with a 100 MW capacity. A year later in
1961, the first combined-cycle plant began operation in Korneuburg, Austria. It
generated 75 MW of electricity.
Since that time, generative capacities
have grown exponentially, and technologies have evolved dramatically. Today’s
combined-cycle plants operate with
greater efficiencies and lower emissions
than any other type of fossil plant, and it’s
realistic to expect these numbers to continue to evolve and improve. Natural gas
plants supply more than half the energy
consumed in residential and commercial
applications, and 41 percent of the energy
used by U.S. industries, all while producing half the carbon dioxide, a third the nitrogen oxides, and one percent the sulfur
oxides of the average coal-fired plant.
Admittedly, a brief anecdotal history
such as this will probably not directly
influence the technological or business
decisions of natural gas power plants in
the modern age. But perhaps the information is valuable anyway, if for no other
reason than the sense of satisfaction it
can bring us. Natural gas formed when
organic matter from untold millions of
prehistoric plants and animals was covered over by strata, decomposed, and
submitted to unimaginable heat and
pressure across the millennia. In this
way the solar energy that living matter
once absorbed from the sun was stored
as carbon beneath the ground. Quite
literally then, we now power our most
sophisticated computer systems and
communications networks on the historical light from a single star, or at the
very least on the backs of John Deeresized lizards and Cessna-scale dragonflies. We’ve come a long way baby!

ifferent industries have developed their own definitions
of—and approaches to—
safety culture. Rather than learn from
one another and adopt the standards
and practices that produce the best results, for the most part, industries have
evolved their own unique strategies and
tools that they are comfortable with.
This trend may very well be related to
the drastically different safety performances found across industries and
evenbetween groups within the same
industry.
Take U.S. electric utilities, for example. Safety on the transmission side of
the business has made notable progress
over the past century. However, the
transmission industry still withstands
fatalities every year. No one would say
that people in transmission are cavalier
about their work or would minimize
the frequency and level of hazards they
face regularly. It cannot be ignored,
however, that it is not unusual for transmission companies to have fatalities, in
addition to serious accidents and injuries, in any given year.
What is striking about this stubborn
trend is the apparently limited crossover
of safety culture lessons learned from
right next door. Within the same utility
companies, transmission may be fairly
isolated from nuclear power plants
when it comes to safety culture. Admittedly, there are significant differences
in their operations and regulations; as
well, there are the unique challenges of
nuclear power. While you could focus
on the differences, transmission and
nuclear generation are interconnected
– literally - and if one side of the equation was accidentally killing workers
www.power-eng.com
frequently and practically never doing
so on the other side, one could be curious whether there were more learning
opportunities that could be adopted.
With their relentless focus on safety
culture and high standards for safety
behavior, U.S. nuclear power plants
consistently have the safest industrial
environments in the world. A look at
the Department of Labor accident, injury, and fatality statistics shows that
nuclear power plants are safer working environments than elementary
schools, and significantly safer than
transmission organizations and any
other industrial workplace. What has
nuclear power done to achieve and sustain these gains?
Although the nuclear power industry started making accident and injury
safety improvements many years ago,
they have increased and sustained
safety performance to stratospheric levels since it began its immersion in the
concept of nuclear safety culture. Focus
on culture came out of lessons learned
from the 2002 incident at the DavisBesse Nuclear Station.
In 2002, an NRC inspection found a
football-sized hole in the reactor containment vessel, which left only a thin
layer of stainless steel barrier. Although
it was caught before any consequences
occurred, the finding shocked the industry because inspectors had not
found the degradation in containment
until it had gotten as large as it did.
Moreover, this was at a station that had
received high ratings and was widely
considered a well-run plant.
Over the next two years, multiple
investigations and analyses revealed
issues pertaining to an organizational
culture that had an impact on safety.
The industry issued a significant operating experience report that required all
plants to conduct assessments on their
own safety cultures. Since then, safety
culture has taken on a life of its own to
the point where everyone from plant
workers to senior leaders across the
country are deeply committed to creating and maintaining a healthy safety
culture.
Prior to the Davis-Besse incident, the
industry didn’t focus on nuclear safety
culture, per se, although standards
around conservative decision-making
and nuclear professionalism may have
laid the groundwork. Why and how did
nuclear power plants embrace safety
culture? Because people have seen that
it works—by building strong organizations, engagement, transparency, safety
results—in addition to better plant performance. The “how” involves a significant focus on aspects of organizational
culture that ultimately impact safety.
Since the Davis-Besse incident, the
industry has institutionalized quality,
regular safety culture assessments, continuous oversight, and the reinforcement of safety culture behavior. The industry has defined safety culture as an
“organization’s values and behaviors as
modeled by its leaders and demonstrated by its members that serve to make
safety an over-riding priority.” At nuclear power plants, people are challenged
to consistently demonstrate commitment to safety through their decisionmaking, behavior and work execution.
Commercial nuclear power has
taught us that commitment to safety
culture is a major undertaking. But if it
saves a life, it would be worth it.

ON-SITE POWER
CHP: Energy

Economic analysis and design strategies
for cogeneration increase industrial
competitiveness

arge, energy-intensive commercial and industrial businesses face steep capital costs
and business risks when
investing their resources in
green/brownfield projects, equipment
upgrades or expansions to utility infrastructure facilities.
An on-site energy solution -- combined
heat and power (CHP), also known as
cogeneration or “cogen” -- enables industrial facilities to achieve greater energy independence, efficiency and reliability, reduced environmental impact, and lower,
more stable energy costs. The combined
benefits can increase an industrial company’s competitiveness.
CHP is more efficient because it requires less fuel to produce a given energy
output compared with traditional standalone steam generation and separate
grid electricity generation, and it avoids
transmission and distribution losses that
occur when electricity travels over utility
power lines.
The cogen plant increases reliability

because it can be designed to provide highquality electricity and thermal energy
independent of the power grid, decreasing the impact of outages and improving
power quality for sensitive equipment.
In fact, CHP is the only real alternative
for most industrial production sites to
achieve N+1 reliability both for electricity
and steam. Only facilities with very large
energy demands (greater than 50 MW)
typically have the leverage required for
the utility to provide electric power service from two independent sources.
CHP can save industrial facilities considerable money on their energy bills
thanks to its high efficiency and independence from increasing retail electric
prices; that being said, the project is sensitive to the delivered price of natural gas
because of higher usage to generate both

steam and electricity, albeit at higher efficiency.
Because less fuel is burned to produce each unit of energy output, CHP also reduces air pollution and greenhouse
gas emissions, which may free up or create environmental
emissions credits for the host to be used elsewhere or sold
to the market. As a state-of-the-art, sustainable energy alternative, cogeneration can also contribute to branding as
a green enterprise.
When job creation is an important advantage to the
community in which the plant operates, a CHP project
further differentiates the company as a good corporate citizen. Most cogeneration projects increase staff and enhance
plant operators’ careers because they are taking control
over their energy production rather than simply buying
from the grid. Third-party CHP projects have been successfully implemented in both closed-shop and open-shop labor environments. From an economic standpoint, job creation also enables the company to leverage investment tax
credits, production tax credits, and tax abatements.
Moreover, partnering with a third-party on-site energy
provider, who designs, builds, owns and/or provides O&M
services for a customized, private cogen plant allows the
“host” to reduce the capital investment and operating risks
associated with a self-build CHP project while reaping all
of these benefits.
While CHP offers many potential advantages that
add up to increase an industrial company’s competitiveness, not every site is an ideal candidate. Here are
insights for effective economic analysis and decision
making, as well as fundamental design strategies to
optimize the benefits.
THE ECONOMIC ANALYSIS:
FROM “10,000 FEET”
First, it is important to understand the current utility environment of a potential CHP project. It may
run counter to expectations, but most local utilities
operating in today’s relatively deregulated utility market are not opposed to customers implementing CHP.
A screening assessment to analyze the value of a CHP
project can be performed with basic thermal and electric
loads and billing data, as well as a simple understanding of
current energy delivery operations.
As part of the economic analysis, a potential host company will want to compare current utility costs with project
costs after implementation of a CHP plant. Remember to
base the analysis on the appropriate tariff structure, which
may differ from the current structure; in fact, if a company
brings more power generation on site, it may be eligible for
a different rate structure, including deductions based on

benefit both partners on a CHP project.
While there are several infrastructure
funds that have a relatively low cost of
capital, they also have a relatively narrow
risk appetite. As a result, they are attracted to investing in CHP projects, but they
prefer partnering arrangements that limit
their development, construction and operational risks.
There are opportunities in CHP projects to improve the steam balance of a
site. If, for example, the site is replacing
existing electric chillers with steam absorption chillers, then it enhances the
economic case for cogen. When electric
chillers are at the end of their useful life,
instead of replacement in kind, it may be
the time to switch to steam absorption

self-generation during on-peak hours,
i.e., reduced consumption from the utility when the utility system is experiencing its highest demand. So it can prove to
be enlightening to reach out to the company’s utility account representative with
questions about potential rate structures
under CHP. The answers may provide
additional economic justification for a
cogen project.
The dollar value of reliability is another key factor in the analysis. Just as an
outage can be quantified as production
dollars lost -- often, into the millions depending on the length of the outage -- the
dollar value of cost avoidance should be
part of the analysis to get a true picture
of the potential magnitude of the benefits
of cogen.
Similarly, the security of the investment in a new CHP plant -- that is, site
and product life cycle and market stability -- are of great importance in the highlevel economic analysis of a cogeneration
project, whether it is a self-build project
or a partnership with a third-party provider. Specifically, the economic analysis
must consider whether or not the operation of the site and the product life cycle
will be consistent with the project financing term, i.e. the value proposition of a
CHP plant at an industrial plant with a
ten-year life expectancy must include the
cost to pay off such a CHP plant in ten
years.
When a partnership with a third-party
provider is on the table for discussion,
the host’s and the provider’s risk-adjusted
costs of capital are typically very close, so
there is very little difference between selffinancing or financing through a third
party. However, the key factor is their
respective hurdle rates for discretionary
projects. Where the typical industrial
company today is looking for a two- to
three-year payback on savings from capital projects, third-party energy services
providers are looking for a six- to eightyear payback on most projects, so they
have some leverage that can financially

Sample utility forecasts for CHP assessment
In fact, one of the key economic decisions for each party to a self-build or
partnership project is this: what level of
risk are you willing to assume in terms of
capital cost risk, performance guarantees,
O&M costs and energy prices, and what
level of risk do you want a third-party onsite energy services provider to assume?
The spreading of that risk among the
parties is one of the crucial factors that
determines the final costs and contract
structure of a third-party provider CHP
project.
THE “DEEP DIVE”
If the initial high-level economic analysis of a potential CHP project is positive,
an in-depth analysis examines a number
of key issues, including the opportunities for CHP to improve the operation of
the site, “hidden” costs, commodity price
variability, and contractual obligations.
chillers because the plant will be generating cost-effective “fuel” for them.
Certain “hidden” costs/factors should
be included in the analysis. For example,
the costs of management oversight will
inevitably change when heat and power
are generated on site rather than being
purchased from utilities.
Other factors include:
• Impact of host credit on ability to finance project
• Accounting treatment of project
ownership: depreciation, etc.
• Development costs, interest during
construction, and initial working
capital cost
• Residual value and/or any asset retirement obligations
• End of term or early termination provisions
• LD’s for non-performance
• Scheduled or unscheduled major
www.power-eng.com
maintenance or equipment replacement
• Casualty losses: insurable or noninsurable
• Commodity usage and price risk
• Inflation risk
• Change-in-law risk
• Assignment provisions
There are also many peripheral costs
that must be carefully assessed, including
the costs to bring in utility gas if there is
not currently a adequately sized gas line
to the plant.
Key cost factors also include the longevity or viability of the site and product, annual operating costs, and financing arrangements. For example, a swing
production site may be the first to go, but
on the other hand, a marginal site that
increases its operating efficiency and reduces costs may move up in the corporate
hierarchy accordingly.
Commodity price variability is also a
key consideration in the analysis. Forecast information is available from the Energy Information Administration, a part
of the Department of Energy, or from a
number of energy consulting firms.
Just as the economic analysis must
consider whether or not the operation
of the site and the product life cycle will
be consistent with the project financing
term, the analysis must also weigh the
impacts of the contractual obligations
during peak production periods and during downturns. It may not be possible to
predict when the business cycle is going
to go up or down, but it is important to
generate reasonable estimates of the site’s
energy requirements at peak production
and during a period of market downturn
-- over the 10- to 15-year life-cycle of the
CHP project -- and plan for how the company will meet its contractual obligations
to the project in both scenarios.
WHERE IS THE
TIPPING POINT?
Is there a tipping point for a CHP project based on scale? For some third-party
www.power-eng.com
providers, electric power generation of
4-5MW is marginal; however, this number is trending downward as the cost of
capital drops because it does not require
quite as much throughput to pay the debt
service for that capital. Today, even projects generating 2-3MW can be attractive
for a third-party developer to partner
with a potential host.
Fundamentally, the tipping point
analysis requires that the potential host
monetize or put specific values on all of
the components above, and then determine whether CHP represents a rational

economic decision under the various
market scenarios. Finally, developing a series of operating scenarios for
evaluation, whether it is a Monte Carlo
analysis or another, determines the
percentage of time that a CHP plant
will generate positive financials versus
the percentage of time that it will not
-- if it is a 90/10 proposition, then most
companies will agree that the project
has reached the tipping point.
In the process, the company can
compare the costs of capital and the
value of the risks for a self-build project versus the cost of a third-party provider. The cost of capital is not typically the deciding factor -- the deciding
factor is a comparison of the hurdle
rate for internal projects versus that for
a third-party provider.
Industrial companies tend to look at
the implied cost of capital in a thirdparty provider’s solution and compare
it to their own internal costs of capital
instead of comparing it to their own
internal hurdle rate.
A third-party provider’s hurdle rate
is always going to be higher than the
costs of capital because it has a number of risk premiums -- for construction, operating and performance risks
-- and profit built into its costs.
In fact, there are few energy projects
that will ever have a return that is high
enough to meet a discretionary hurdle
rate for an industrial plant. Maybe the
real question is “What is the cost of the
status quo?”
This speaks to the importance of
identifying the right metrics for the
analysis when considering a third-party provider: look at the savings rather
than internal rate of return (IRR). It
is almost automatic for a company to
calculate the IRR, especially if one has
never before partnered with a thirdparty provider. Remember that it will
be the provider that makes the capital
investment, so IRR is the provider’s
economic issue, not the host’s.

EQUIPMENT SELECTION:
“BIG” OR “SMALL”?
ASSESSING A
POTENTIAL PARTNER
Equipment selection becomes the
rational result of the economic analysis -- the tipping point and analysis of
long-term needs -- and then selecting
the equipment that generates the most
savings for the site. Big equipment
provides the site with a lot of reserve,
while small equipment provides high
utilization; selection must be appropriate for the character of the plant.
Moreover, it is important to choose
equipment that can be upgraded easily
and will age well with the plant.
Changes in environmental regulation or a significant change in the
customer’s operating system can have
an effect on the viability of CHP as a
site’s energy solution. In addition to
improved energy supply economics
and operating availability, CHP projects create benefits for hosts focused
on CO2 emissions reductions due to
higher efficiency and lower overall
emissions.
With changes in environmental regulations, one of the nice features of CHP
is it creates additional value streams because of its energy efficiency.
Finally, if taking the route of a partnership with a third-party energy provider,
be certain that the partner aligns its interests with yours.
One characteristic to consider is transparency; do you want to partner with a
company that is going to offer an opensource, non-proprietary solution or do
you want a partner that will provide a
“black-box” solution and you wait at the
end of the pipe and wire for services?
Also, consider whether you want a
partner with a long-term “ownership”
perspective, or one that will be focused
on taking the front end risk and then
“flip the house” to an equity player.
Once the project is up and running,
make sure that a project is appropriately
managed to be technically and commercially optimized,
This includes future expansion or contraction with changing energy demands,
future operational changes due to changing market commodity pricing/availability, and incorporation of potential enhancements such as additional services,
demands, feedstocks, etc. available onsite or at neighboring facilities.

THE COAL ASH RULE:
How the EPA’s
Recent Ruling Will
Affect the Way
Plants M
Manage
BY TIM MISER,
ASSOCIATE EDITOR
L
CCRs
ast December, the Environmental Protection Agency
(EPA) published its final
ruling for the regulation of
coal combustion residuals
(CCRs). Commonly referred to as the
“coal ash rule”, the new policies have
largely been met with acceptance, even
relief, with many industry representatives calling the ruling a fair compromise.
The final CCR ruling follows six years of
debate about how best to handle a potentially perilous situation.
22
THE BACKSTORY
In the early morning hours of Dec. 22,
2008, a structurally deficient dike containing an 84-acre unlined surface impoundment at the Tennessee Valley Authority’s (TVA) Kingston Fossil Plant near
Harriman, Tenn. gave way, spilling 1.1
billion gallons of coal ash slurry into the
Emory and Clinch rivers. The accident
was the largest fly ash disaster in United
States history, larger in volume than the
1989 Exxon Valdez or 2010 Deepwater
Horizon oil spills. It flooded 300 acres
of land with up to six feet of solid waste
sludge, toppling trees, damaging or destroying dozens of homes, but injuring
no one. The disaster destroyed power,
water, gas, and rail lines, and killed large
numbers of fish and other wildlife.
The cleanup effort topped $1 billion,
and the Tennessee Department of Environment and Conservation saddled the
TVA with a $11.5 million fine. The TVA
was also required to monitor wildlife
damages for 30 years following the accident. To date, the TVA has spent $40
million studying the effects of the coal
ash release on the river and surrounding
environment. Additionally, the TVA contributed $43 million to Roane County
where the disaster occurred, and bought
180 properties and 960 acres that were
devastated by the accident.

Among the many environmental advocates that became involved in the aftermath of the incident, Greenpeace called
for legal action, requesting a criminal investigation into the TVA’s culpability for
the accident. Local landowners also sued
the TVA for $165 million.
In the wake of the disaster, Congress
held hearings on the accident, and the
House of Representatives passed a bill
that established minimum requirements
for coal ash handling and stripped the
EPA of its regulatory power. For its part,
The EPA proposed new rules that would
regulate coal ash and classify it as a hazardous material.
Notwithstanding the magnitude of the
event and the legal circus that ensued,
coal ash remained largely unregulated for
years following the disaster, as the EPA
delayed issuing a final ruling under intense political pressure from companies
in coal-related industries.
But all this changed in the final weeks
of last year, when in a bid to establish
safeguards against groundwater contamination and air pollution, and to protect
communities from impoundment failures, the EPA announced the first national regulations for the safe handling and
disposal of coal ash.
THE RULING
With the publication of its final rule
under subtitle D (the solid waste provision) of the Resource Conservation and
Recovery Act, the EPA has attempted
to strike a balance between polarized
arguments on both sides of the issue.
While some environmental conservation
groups argued that CCRs should be classified as hazardous materials because of
their arsenic and mercury content, many
power industry representatives countered
that coal ash has beneficial uses and
should only be regulated as solid waste
akin to household trash.
Many in the coal-fired power industry
www.power-eng.com
worried that the EPA would outlaw surface impoundments altogether or designate CCRs as hazardous waste. Ultimately though, the agency omitted to
undertake either action, opting instead
for a more measured approach.
The EPA’s final ruling looks like this:
Structural Integrity
To reduce the risk of “catastrophic failure”, coal-fired power producers must
meet certain “structural integrity requirements and design criteria” for their
surface impoundments. Owners must
periodically conduct assessments that
measure structural stability, minimum
safety factors, and potential for hazards
in the event of an impoundment failure.
They must also inspect impoundments
weekly and monitor unit instrumentation monthly, in addition to developing emergency plans for impoundment
breaches.
Groundwater Purity
Power producers must also meet requirements for “groundwater monitoring
and corrective actions” that include the
installation of monitoring wells, analysis
of water samples for hazardous contents,
and mitigation of contamination caused
by units that do not meet established
standards.
Impoundment Location
The placement of impoundments is
disallowed below the uppermost aquifer,
in wetlands, and in seismic impact zones
or areas that are otherwise unstable. This
standard is retroactive and also applies
to existing landfills and impoundments.
If owners cannot demonstrate that their
facilities conform to these requirements,
they must shut down their impoundments.
Liner Design
To prevent CCR contaminants from
leaching into the ground, all new landfills, surface impoundments, and lateral
expansions must include a composite liner that meets prescribed design criteria.
New landfills must also utilize leachate
collection and removal systems designed
to remove excess leachate from the tops
of liners. Existing unlined landfills may
continue to operate as before.
Operating Criteria
Power producers must address the
day-to-day operations of CCR units by
establishing criteria to prevent negative
impacts on public health and the environment. These criteria must include
standards for air quality, water discharge,
flood control, windborne dust, and
leachate creation. They must also control water run-on and run-off in order
to minimize erosion and protect against
pollution of surface waters.
Record Keeping and Notifications
Plant owners must maintain operating records that demonstrate compliance
with prescribed standards. In an effort to
increase transparency and inform and
engage citizens, facilities must maintain
a publicly available website that includes
information regarding compliance with
groundwater standards, plant corrective
actions, plans for fugitive dust control,
and facility closures.
Inactive Units
To prevent structural failure, inactive
units which no longer receive waste, but
which still contain water or CCRs must
be completely dewatered and covered
within three years to avoid further regulation under the rule.
THE FUTURE OF
COAL ASH HANDLING
Though the EPA’s new coal ash regulations are more moderate than some
feared, they will still prove costly for the
industry. “[The ruling] will make states
and utility companies vulnerable to new
regulatory costs and expensive litigation,” said Sen. Jim Inhofe, R-Okla., and
Rep. Shelley Capito, R-W.Va. in a joint
statement.
But the new ruling will also open up
market opportunities for companies
involved in the transport of CCRs from
their post-boiler origination to their

“As facilities review their technical

decisions. When they do this, there is a
tendency to convert facilities from wet to

greatly minimizes the amount of future
risk that would otherwise exist when operating wet systems that utilize surface
impoundments, because the potential for
structural breaches and leaching can be
entirely circumvented. Removing water
from the equation increases predictability down the road.”
Allen-Sherman-Hoff
Allen-Sherman-Hoff, a division of Diamond Power International, offers bottom
ash handling systems that allow power
plants to continue to transport CCRs in a
wet stream. “Fly ash systems will almost
universally be converted to dry handling,” says Tom Moskal, general manager. “This is especially true considering
the Effluent Limitation Guidelines (ELG)
due to come out later this year. But there
will continue to be a whole host of solutions for moving bottom ash. I believe
that relatively few plants will convert to
totally dry systems, mostly because of
the expense associated with modifying
and excavating the bottom of the boiler
and its foundation.” Moskal believes that
submerged chain conveyors offer a good
wet-dry solution to bottom ash handling.
Like McDonough, he sees the promise
that remote dewatering systems offer
plants who seek a retrofitted solution.
Allen-Sherman-Hoff offers its Remote
Submerged Chain Conveyor (RSCC) as
a solution that transports the vast bulk
of both large and fine particles up an inclined dewatering path which uses gravity to drain away liquid. The system results
in coal ash with a water content of 20 to
30 percent by weight, which is retained
liquid mostly captured by the capillary
action inherent in porous substances like

bottom ash.
But this is not to imply that all CCR
systems will eliminate surface impoundments. “I know of one Midwestern utility that is keeping its ponds,” says Moskal.
Bergemann’s activity is on the elimination of surface impoundments. Ron
Grabowski, business development manager for the company, says some plants
have already begun to retrofit existing
Beumer’s pipe conveyor system entirely
encloses the coal ash, preventing cross
contamination with the environment.

“But instead of serving as the gross separation device, the pond will serve only to
contain the water that has already passed
through the RSCC. The pond, then, will
not be removing the bulk of the coal ash.
Rather, it will do the final job of settling
out the very fine particles over time. This
combined approach minimizes the burden placed on the ponds. They don’t fill
up as quickly as they otherwise would, so
they can be used for many more years.”
Moskal is skeptical that ponds will
represent a majority solution, however.
“Because of the new monitoring requirements imposed on power producers by
the EPA’s ruling, my guess is that more
ponds will be closed than kept open.”
Clyde Bergemann
Currently the main focus of Clyde

bottom ash systems with newer technologies.
“We supplied a client with our DRYCON state-of-the-art bottom ash handling system, which is completely dry,”
says Grabowski. “This system has already
saved the plant over $1 million a year in
operational costs compared to the original wet bottom ash system. We also offer
a very unique technology called ASHCON which redirects bottom ash slurry
away from ash ponds for dewatering and
storage. Systems like these help plants
meet the CCR regulations, as well as the
anticipated ELG requirements. “
Beumer
Beumer considers the EPA’s new ruling, as well as its allowance for surface
impoundments, to be good for the industry, but nonetheless focuses its development efforts on dry coal ash handling
and landfill disposal. The company does
not offer wet or wet-dry hybrid systems
for CCR delivery and storage. Rather, it
designs conveyor systems for everything
from airport luggage terminals to bulk
material transport systems, like those required for coal ash handling.
“The company’s major contribution to
the coal ash handling process is its pipe
conveyor system,” says Brian Giese, vice
president of conveying and loading sales.
“Our system is comprised of a conveyor
that can be rolled into a pipe shape during operation, entirely enclosing the coal
ash in order to protect the material from
the environment, and the environment
from the material.” This is accomplished
by a conveyor that begins and ends as a
standard three-idler trough conveyor, but
which is rolled into its round shape while
in transit via three additional idlers. The
conveyor is rated for 1200 tons per hour,
and can make horizontal and vertical
curves to follow the terrain of a specific
site. A single run can reach greater than
six miles.
The German Beumer has also partnered with Eurosilo in the Netherlands to
build automated conveyance and storage
systems for CCR handling. This allows
plants to store their CCRs in such a way
as to desynchronize the conveyance process from the pickup and disposal process. Normally a conveyor must operate
the entire time that ash is being trucked
away. If the conveyor stops, the trucking
to landfills must also stop. The automated
storage system decouples these two processes, so that previously-conveyed ash
can be stored and automatically retrieved
at a later time, when waiting trucks can
transport it to the landfill. Trucks can
be loaded even when the conveyor belts
are not actually operating. This allows
for simpler scheduling at plants, because
it normalizes employee shifts and overtime.

Cleaning
Practices
F
or power plants burning
anything other than natural gas, boiler cleaning
is an important part of
keeping the plant working efficiently.
Over time, boilers will build up ash
that will form slag deposits on the
boiler. Slag acts as an insulation that
protects the tube from the heat of the
boiler, creating a need to use more fuel
to reach the same temperature and produce the same output as a clean boiler.
Cleaning slag deposits inside a boiler
can increase boiler efficiency between
30
1 percent and 4 percent. Clean boilers
can also reduce emissions produced by
a power plant because less fuel is required to produce the same amount of
power.
While the importance of boiler
cleaning is clear, power plant operators have many options when it comes
to techniques used to clear slag and
ash buildup. Cleaning practices vary
from offline cleaning, which requires
a planned outage, to online cleaning
that can occur while the plant is still
operating. Methods can use everything from sound waves to dynamite.
ACOUSTIC CLEANING
One option for boiler cleaning is an
acoustic cleaning system, which can
knock ash off boiler tubes or selective catalytic reduction systems with
acoustic energy without risking damage or fatigue to the units. While this
can be done by using acoustic horns
that can be retrofitted onto boilers,
Advanced Acoustic Technologies LLC
uses a technique that is engineered
specifically for a plant.
“Unlike the horn suppliers, our
acoustic devices are part of an engineered, integrated system where the
frequency produced by the acoustic
device is determined by 3D element
modeling,” AAT co-founder Robert
van Dam said. The process is similar
to flow modeling, except the company
looks at the acoustic aspects of how
sound waves behave in an enclosure.
The company’s WaveMaster Acoustic Cleaning systems provide continuous, online, volume cleaning with soot
blowers used in a remedial role, van
Dam said. The company uses acoustic
www.power-eng.com
modeling to determine the natural
frequency of the flue gas and decide
the proper frequency for the custom
system as well as where it needs to be
placed in the boiler.
“Our acoustic cleaners are designed
to be operated continuously if that is
required for the application,” van Dam
said. “There’s no erosion. It’s online,
so it’s running when the boiler is running, and by being specific with the
frequency and the location we can
place the acoustic effective area where

we want it. We’re not just cleaning what
is directly in front of our device. We’re
cleaning a volume because the acoustic
cleaner is in resonance with flue gas.”
Acoustic cleaning works especially
well on dry and dusty deposits, van
Dam said. The company works with
areas where ash is below the fusion
point, such as horizontal tube banks
in a utility boiler. The technology is
not as effective in superheaters or other other areas where the ash is likely

partially molten.
According to van Dam, the company
has seen excellent results on a wide variety of fuels, including Powder River
Basin, pet-coke, bituminous and subbituminous coals. The fully-optimized
sound field can penetrate throughout
several tube banks with the application of only one or two acoustic cleaners. Van Dam said the system is used to
clean the entire convection pass at Tennessee Valley Authority’s 1,300-MW
Cumberland plant, which is 67 rows of
tubes, with two acoustic devices.
WATER LANCES
Another method for cleaning slag
from a boiler is using high-pressure
water jets. Thompson Industrial Services uses high-volume, specialized
hydroblasting equipment, with pumps
that can send up to1,200 gallons per
minute through the hoses. The company also uses remote-controlled robotic
cleaning systems and other automated
tools to clean boilers.
Thompson
Senior
Business
Development Manager Carl Wise said
the company is able to use water lances
for both online and offline cleaning, although whether online cleaning is possible may depend on the specific boiler.
“You have to do online cleaning from
strategic positions because you have to be
very careful spraying the water directly
into the boiler while it’s operating,” he
said. “It’s an extremely critical process.”
Whether cleaning can be done while
the boiler is online depends on the
particular boiler. Although the company routinely cleans boilers without
having to shut them
down, Wise said it may
not be possible in every
situation.
Online cleaning has
multiple advantages when
it is possible, however.
“If you take a boiler
completely down, it takes
a lot of time to bring it
back up,” Thompson Senior Sales Representative
Jim Walker said. “It saves
the utility time and money to have that boiler up
and running when we do
our deslagging.”
Because of the highvolume pumps, Wise
said the company is able
to clean farther distances with their lances and
can be more effective
because the lance can go
out more than 40 feet on either side of
the lance.
Thompson also performs many other
types of cleaning for power plants, including hot ash removal and using a process involving dry foam to remove combustible dust, which can create a safety
hazard on the external part of the boiler.

put all of it in a pickup truck and clean
any boiler,” he said.
Explosives also have an advantage
in areas where plants are concerned
about water use, he added.
“Water is really scarce out west, and
this is another reason explosives are
being used predominately in the western plants,” he said. “They can’t afford
to waste a drop of water, and by using
dynamite they’re able to save their water and clean their boiler at the same
time.”

GENERATOR SETS
Comparing
NATURAL GAS
and DIESEL
Generator Sets
Do the Old Rules Still Apply?
O
BY RAFAEL R. ACOSTA, HIPOWER SYSTEMS
nly a few years ago, traditional logic for generator sets (gensets) held
that diesel meant reliable and inexpensive

but also noisy, loud and messy. Natural
gas meant expensive and temperamental but also quieter and cleaner. Today,
thanks to the development of new technologies in engines, enclosures and other
components, the differences between diesel and natural gas generators is no longer
so clearly defined.
Additionally, many firms follow conventional logic in their comparisons of
these two fuel types and fail to give sufficient weight to the operating realities of
their particular applications. In this article, we’ll take a look at both new developments and long-standing considerations
that impact generator selection by fuel
type in the power generation industry.
THE ENGINE EQUATION
Traditionally, the viewpoint has been
that diesel engines provide response,
power and longevity, while natural

operating mini-grids, a new generation of
generator enclosures is increasing choice
and reducing or eliminating some of the challenges with diesel. Photo courtesy: HIPOWER
Systems
gas engines are more environmentally
friendly. Although the environmental
argument for natural gas still holds true,
diesel is no longer the clear winner in
terms of power and response. Sparkignited (natural gas) industrial engine
manufacturers can now optimize the
RPM of these engines to make their transient response similar to that of diesel.
Manufacturers are also producing natural gas units that can meet the 10-second
startup requirement for backup systems
that is traditionally associated with diesel
engines, alone.
Use of gear-on-gear powertrains or
two-pole alternators (as opposed to traditional four-pole alternators) has increased
the overall performance and power of
www.power-eng.com
natural gas engines, as well. Manufacturers have also incorporated stronger, more
resilient engine parts, such as hardened
valves and seats, to boost performance
and increase reliability.
In the area of energy density, there is
no doubt that diesel has greater peak energy density than natural gas-by a factor
of more than of three (generally 129btu
versus 37btu). Even here, there are mitigating factors that may tip the scales in
favor of natural gas.
Density is impacted by both engine
and fuel conditions. A poorly maintained
diesel engine, or one running sludgy fuel
from a fuel tank filled with particulates,
likely will outperform a natural gas engine, but it will not perform at its peak.
Even more significantly, diesel engines
have a sweet spot of 50-70% of load, with
80% being the recommended maximum
for long-term prime operation. Running
them under a lighter load for long periods
of time results in wet stacking, a condition that sends unburned fuel and soot
into the exhaust system.
Operators that run engines under light
loads often employ load banks to consume the excess energy. This approach
reduces wet stacking but can waste a
considerable amount of fuel. As an alternative, those operators could instead
choose natural-gas-powered generators,
which burn hotter than diesel engines.
These engines are less likely to experience problems with unburned fuel, even
if they are run at a lighter-than-optimal
load.
BUILT TO LAST
Regarding longevity, diesel engines
still tend to have longer lives, on average,
than natural gas engines. However, many
of the new technologies mentioned
above not only enhance performance in
natural gas engines; they also increase engine resilience and longevity.
In short, companies that plan to keep
their engines operating at peak condition
will still likely enjoy the greatest longevity
from a diesel engine. If they allow it to
fall prey to the operating challenges discussed in the previous section, longevity
will suffer-in extreme cases, potentially
cutting engine life in half.
For firms that use generators only for
backup power, a natural gas engine may
provide nearly the same effective life,
given how infrequently it is used. Other
considerations such as continuity of fuel
source also come into play, perhaps outweighing diesel’s benefits of performance
and engine life.
COST COMPARISON
It’s a common misconception that industrial diesel engines are considerably
less expensive than comparable natural
gas models. Below 150kW, natural gas
engines are actually more cost effective,
even without factoring in the fuel differential.
For applications where more kW are
required, power producers can create parallel configurations of smaller engines to
provide them with the cumulative kW
needed for the operation. Parallel systems have the advantage of supporting
load sharing and management, making them one of the most cost-effective
and environmentally friendly options,
in terms of fuel use, for variable load
applications such as mini-grids. Add to
this savings the reliability and scalability
of parallel systems where they replace a
single, larger diesel generator (such as for
backup power) and the benefits of such a
solution are considerable.
For the past two years, natural gas
genset suppliers have also been touting
fuel prices as cost benefit. While the fall
in natural gas prices is certainly making
them a more attractive option, plummeting oil prices are having a similar effect
on diesel generator fuel. We won’t make
a prediction here, because the outcome of
fuel prices is anyone’s guess.
SAVING THE PLANET
One of the big advantages of natural

gas, of course, is that it burns more cleanly than diesel. This comparison is exacerbated for any of the operating conditions
mentioned in the previous section, where
wasted fuel increases soot and dangerous
emissions.
In addition, shortened engine life from
wet stacking, light loads, inadequate
maintenance and other common diesel

monitoring must be verified through reporting, and if operators allow engines to
fall outside acceptable ranges with poor

should consider all of these factors before
they make an engine choice.

BI-FUEL IS NOT

if you would like more information.
For the purposes of this article, the
point is that bi-fuel solutions do not
work both ways, and due to differences between the fuel types and the
respective ignition systems (compression versus spark-ignited), we do not
anticipate they ever will. As a result, if
you want the option of burning diesel in any percentage, along with the
flexibility to burn a large amount of

problem, not only for the environment,
but also for regulatory compliance with

One of new technologies beginning to

technology, diesel engines can run up to
75 percent natural gas, with the gas being
introduced through the air intake.

They can come equipped with bifuel add-ons, or operators can add
them at a later date.
FUEL SUPPLY
AND STORAGE
Fuel handling is another area
where diesel gensets and natural
gas generators are not converging.
As with other criteria, the benefit
of one over another often depend
upon the situation and need.
For example, it is widely promoted that natural gas delivered from a
pipeline can run a generator indefinitely in the case of a disaster. This
is true in most situations, but there
are caveats. It’s fairly evident that
any natural disaster that disrupts
the earth, such as an earthquake,
can cause supply disruption.
Of greater surprise to many enterprises, weather-related events
such as hurricanes and tornadoes
can cause damage to buildings that
disrupts their natural gas lines.
This in turn can impact gas pressure in the surrounding area or
even force a utility to shut the gas
supply off.
Any power provider considering
a natural gas genset as a backup
power supply to keep utility offices
running in the event of storm or
for other reasons should be aware
of these possibilities.
For diesel, fuel availability is limited only by delivery frequency. If
diesel trucks can service a site, then
fuel supply is no problem.
However, in remote locations
that use generators for backup or
prime power, weather can factor
into fuel delivery, as well.
Additionally, diesel fuel can become contaminated with water,
particulates and algae over time.
(Ultra-low-sulfur diesel fuel is

conditions,
driven
by an abundance of
natural gas fuel, recent
advances in gas turbine technologies
and more efficient combined-cycle
component operation, have placed
enormous demands on critical valves
within thermal generation systems.
Seeking to align their technical and
commercial goals, market leaders are
challenging traditional mindsets by
performing new, objective analyses of
valve lifecycles and product costs to
determine the most judicious strategies for keeping their power plants operating at optimal efficiency.
Corporations that had focused solely on large-ticket critical components
– turbines, generators, heat recovery
steam generators (HRSGs), boiler feed
water pumps (BFWPs), etc. – are now
turning toward a more inclusive approach that takes into account generation components, such as valves,
once considered non-critical to daily
operations. In the face of ever-evolving
electrical dispatch requirements, these
components are taking on renewed
importance as they move from monthly or biannual service duty to a daily
cycle.
This article focuses on two of these
now-critical components, small bore
40
vent valves and drain valves, reporting
research findings that repairing these
valves is more prudent and economical
than replacing them.
Why focus on vent and drain valves?
Modern advance frame combinedcycle power facilities operate in a dispatch environment where cold starts,
accelerated ramp rates and low load
conditions are the norm and where
Balance of Plant (BOP) equipment accounts for more than half of all forced
outages. Analysis by Pentair Valves &
Controls revealed that valves are a significant contributing factor in forced
outages, primarily based on their application numbers and the severity of
their service applications. As we segregated the valves based on their duty
service as it relates to cycling activity,
we found that small to medium bore
equipment drain and vent valves with
higher duty cycles exhibit a critical
component profile not previously associated with these former commodity, or buy-out, valves.
Pentair proceeded to review valve
products designed for combined-cycle power facilities in these small to
medium bore drain and vent applications. Applications were selected for
their severe duty cycles (temperature
and flow), directly related to cycling of
the combustion turbine/heat recovery
steam generator, and their strict boiler
and piping code design requirements.
Our project objective, beyond continuous product improvement, was to evaluate the products’ overall contribution
to the customer’s corporate strategy

THE STUDY
We selected Pentair’s 1.5” 1700#-4500# Yarway Welbond
High-Pressure Globe valve for evaluation. This valve’s design is consistent with our previous Six Sigma forced outage
research findings. It exhibits a high profile of widespread
application in the global power generation market for HRSG
drain and vent applications. It also boasts a long tradition
in power generation service applications in general, and it
is refurbishable, often fitted with an automated operator for
cyclic duty.
Our objective was to independently review and analyze
the average actual repair cycle cost associated with this
valve, operated within a specific thermal cycling duty for an
HRSG vent and drain application. In our study, these valves
were located predominantly in automated vent applications
for the HRSG, while larger bore Pentair (4”-6”) valves were
applied to the HRSG drain applications, primarily based on
individual HRSG module design criteria. Each of the combined-cycle units utilized in the study exceeded 250 MW in
total generation capacity, were of advance frame combustion
turbine design, were equipped with a triple-drum HRSG,
had been automated specifically for cycling duty, and were
operating in the North American power generation market.
These units see multiple fast starts and cold starts, and varying daily load-range conditions, and operate within a generation grid where renewable energy is present. As our study
progressed, it became apparent that certain valve repair and
manufacturing impact similarities among this valve design
class grouping could be identified and then extrapolated to
the larger (4”-6”) Pentair valves not included in our study.
This case study provides insight into the typical costs associated with the average lifecycle of a repairable Yarway
Welbond 1.5”, 1700#-4500# pressure class valve operating
in standard steam service application. The specific product
utilized for this detailed cost analysis was the Yarway Welbond 1.5”, F-22 material, 1700# pressure class valve, operating in the HRSG automated vent service for power generation application. Both hard and soft costs related to these
valves’ lifecycles will be determined. These severe service
duty valves do require periodic inspection and maintenance
as part of normal operations.

COST SUMMARY
Example A reflects the hard costs
associated with a typical Yarway Welbond valve repair after routine periods
of operational service. Scope of repair
consists of the valve disassembly/reassembly, the use of Yarway specialized
tooling for the refurbishment of the
valve seat, lapping of valve disc assembly (if required) and valve stem packing
replacement.
*Yarway Welbond 1.5”, 1700# pressure class valve tooling (packing and
backseat removal part #5617B) consists
of a mandrel with reusable cutters sized
specifically for the valve being refurbished. This tool can be obtained from
the OEM (suggested list price is $2,700
each). Tooling cost will be applied to
each valve refurbishment cost cycle in
the Repair vs. Replace analysis table.
*Insulation costs are not calculated
in the repair summary, since the valve
remains in position, and packing may
be accessed without disturbing the existing valve body insulation.
Typical 2.5 hours to inspect and repair using the proper valve tool kit.
Example B reflects the hard costs
of a typical Yarway Welbond valve replacement after routine operational
service. Scope of replacement consists
of insulation removal, valve removal,
valve replacement, weld procedure,
NDE procedure, and insulating the
valve body and adjacent piping.
*Equipment cost has been excluded
from this cost exercise, since it may
vary significantly by location, company and corporate accounting practices.

Although more difficult to quantify,
soft costs must be accounted for in the
Repair vs. Replace decision process. In
recent years, site operational responsibilities and global stewardship in the industry have increased the traditional list
of soft costs associated with performing
routine valve maintenance tasks. The
following activities impact the realized
cost of the replacement valve project
considerably, but have minimal impact
on the actual project cost.
Inventory Control: Valve manufacturer, size, material, pressure rating,
configuration, quantity, etc. all must
be updated and recorded in warehouse
inventory control and workforce management software programs each time
a valve is replaced in a process system.
Welding: Prior to the physical practice of welding the replacement valve
into the process system, you must validate and record the welder’s qualifications, confirm that the weld procedure
is correct for the valve and connecting
piping material, and process application. Local, regional, state and national
governing codes directly and indirectly
associated with the welding process
may translate into additional cost burdens for this activity. Individual underwriters’ requirements for further
historical record retention of the “valve
replacement event” can prove to be an
unexpected/hidden overhead cost.
Nondestructive Examination (NDE):
Minimum code requirements are visual

Environmental: Environmental activities and related costs will deviate
significantly based on project location

to the carbon footprint taxes associated
with the manufacturing process of the

• Data generated through this study
indicate that every repairable
small bore valve functioning in
these duty cycles routinely will
provide significant savings over
their entire service lifecycle, in
comparison to a valve designed
to be discarded after each and every service cycle. Given that each
combined-cycle unit in operation
today utilizes a minimum of 50
1.5”-2.0” valves within this pressure class, functioning in steam
vent, steam vent blocking and
drain applications, annual valve
savings could exceed $261,000.
• In addition to the economic benefits, repairing vs. replacing valves
is consistent with corporations’
commitment to environmental
stewardship. Our industry has
depended in the past, and shall
depend well into the foreseeable
future, on renewable resources at
all levels of the power generation
market spectrum. Whether we define a renewable resource at the
macro level of a source like wind
or solar electrical production, or
at the micro level of a repairable,
recyclable plant component, our
primary objectives remain the
same: industry sustainability and
profitability. All successful corporate strategies today and for future
global power generation markets
will be required to address the
question of product sustainability. Competition for everything
from raw goods in manufacturing
to end-users in developed generation markets will have a profound
impact on our daily operations.
Phrases such as “going green”
and “environmentally friendly”
have been replaced by phrases
like “cost-effective manufacturing environment” and “long-term
fixed O&M costs.” Reducing the
steps in any manufacturing or repair process cycle will ultimately
reduce the process cycle cost. The
marriage of good business processes and strong quality control
measures with consistent repair
practices will result in best-inclass methodologies. Recycling
or the refurbishment of most resources utilized in our industry
today by definition reduces the
total process cycle and is part of
a cost-effective, sustainable business model.
Repairing valves is a viable option for combined cycles or coal-fired
plants. Pentair’s Yarway Welbond repairable valves are a cost-effective and
responsible solution for today’s power
plant operators.
