North American Electric Reliability
Corporation (NERC)
NERC’s mission is to ensure the reliability of the North
American Bulk Power System (BPS)
Reliability - A reliable bulk power system is able to meet
the electricity needs of end-use customers even when
unexpected equipment failures or other factors reduce the
amount of available electricity
Bulk Power System – NERC defines the bulk power system
as electric power generation facilities combined with the
high-voltage transmission system
NERC Responsibilities
• Develop reliability standards with stakeholder input –
Annual compliance report, regional audit report, vegetation
management report
• Monitor bulk power system status in real time
• Assess bulk power reliability and adequacy – long-term 10
year assessment report, summer and winter assessment reports
• Analyze system events (e.g., multi-state outages) – issue
lessons learned
• Coordinate physical cyber security needs
• Train and certify system operators
• Enforce reliability standard compliance – assessing
penalties
FERC, NERC Initiate Review of Electric
Industry Recovery and Restoration Plans
News Release: September 30, 2014
The Federal Energy Regulatory Commission (FERC), working with the
North American Electric Reliability Corporation (NERC) and the
Regional Entities, has initiated a joint staff review to assess and verify
the electric utility industry’s bulk power system recovery and restoration
planning, and to test the efficacy of the relevant Reliability Standards in
achieving and maintaining reliability. Staff selected a sample of
registered entities with bulk power system significance to participate in
the voluntary review.
Effective system recovery and restoration plans are essential to a quick
and orderly recovery from reliability events caused by weather, bulk
power system disturbances or possible cyber/physical attacks. The
objective of the review is to support registered entities in ensuring
reliable restoration of the bulk power system following a reliability
event. The review is not a compliance and enforcement initiative.
But There is Only So Much You Can
Do to Prevent Outages

Board Permits (Contd.)
Generating Certificates
Iowa Code Chapter 476A requires that
Certificate of Public Convenience, Use, and
Necessity (CPCN) may be required for
• Any plant (or combination of plants at a
single site) with total generating capacity
of 25 MW or more (GCU Dockets)
• Waivers can be issued for any plant if the
Board finds that the public interest would
not be adversely affected
12
Generating Certificate Process (Contd.)
Main decision criteria:
Whether the proposed facility will promote
adequate and reliable electric service
Whether the proposed facility will be consistent
with environmental policies, considering
• The available technologies and
• The economics of any alternatives
13
Advance Ratemaking – Decision
Criteria
• Board has to make two findings before utility
can receive advance ratemaking principles:
- Utility has in effect a Board approved
energy efficiency plan.
- Utility must demonstrate that the facility is
“reasonable” as compared to other
resources.
14
Creation of Midcontinent Independent
System Operator (MISO) &
Organization of MISO States (OMS)
• FERC approved MISO as an RTO in 2001 (non-profit)
• Had the effect of accelerating regional transmission
planning efforts
• MISO has an elaborate stakeholder process
• Regulatory Sector is one of the nine sectors which
Advise the MISO Board
• Midwest state regulators through OMS participate in
MISO processes -- provide leader ship and guidance
• Regulators are now a part of interconnection-wide
planning process
• OMS also represents states’ interests before FERC

IOWA ACTED EARLY AND OFTEN TO ADOPT POLICIES TO
ENCOURAGE RENEWABLE ENERGY
– Alternate Energy Production Law (1983, as amended) (Iowa Code
§ 476.41 et. seq.)
• Requires IOUs to interconnect with and purchase from AEPs at avoided cost
• Includes net metering option (500 kW individual capacity limit)
• Includes an RPS of sorts (105 MW combined obligation)
– Advanced Ratemaking Principles (2001, as amended) (Iowa Code
§ 476.53)
• Applies to new/significantly altered 200+ MW baseload generating facilities
and utility-owned or purchased renewable energy generation
• Approval in advance of the ratemaking principles that will apply when
generation goes into base rates
• E.g., jurisdictional allocation, accounting for environmental credits/wholesale
revenues, depreciation, ROE, cancellation cost recovery
Iowa Action on Renewable Energy
– Renewable Electric Generation Law (2011) (Iowa Code
§ 476.53A)
• Specifically states that the State’s intent is to encourage
development of renewable electric power generation, to
encourage the use of renewable power to meet local electric
needs and to develop transmission capacity to export Iowagenerated wind power
– IUB Rules for Interconnection of Distributed Generation
(2010) (199 Iowa Admin. Code Ch. 45, as amended)
• Some expedited review possible
• Differing levels of review, depending upon size of the facility

DG Issues
• Many small providers wanting to sell to the
system– solar/wind/biomass
• Is on way to being significant contributor
• Interconnection issues – safety and
synchronization
• Variable load/delivery
• Is net metering causing improper crosssubsidization (Are utilities able to recover
cost of facilities involved)?
NOI on Distributed Generation
Docket No. NOI-2014-0001
– Grew out of EEP proceedings – debate whether utilities should have
incentive-based renewable energy programs.
– Initiated January 7, 2014, in recognition of the response to increasing
interest in Solar PV, CHP, biomass, and other forms of distributed
generation.
– Purpose to consider the technical and policy issues associated with
potential widespread use of DG. Goal to determine extent of interest,
existence of opportunities and barriers, existence and extent of consumer
protection, safety and/or interconnection issues, and IUB’s role in dealing
with any such issues.
– Working definition: Generation fueled by renewable or fossil-fuel
sources built in order to serve load located at or near the generator
and capable of delivering power to a utility’s distribution system.
– So far, two rounds of comments on questions presented by the IUB.
Eagle Point Solar Decision
• Eagle Point Solar installed PV solar panels on a Dubuque
city-owned building.
• Eagle Point Solar would finance, install, own, operate, and
maintain the solar system.
• PV generated energy will be sold to Dubuque, on a cents-perkWh basis through a third party agreement.
• The solar energy remained “behind” Interstate Power and
Light’s (IPL) meters. The building would continue to remain
connected to the electric grid and purchase some energy from
IPL to satisfy some of the electric energy needs of the
building.
• Alliant claimed the agreement violated Alliant’s exclusive
service territory rights.
• The Board agreed with Alliant and issued an order in 2012.
Eagle Point Solar Decision (Contd.)
•
•
•
A Polk County District Court Judge reversed the
ruling a year later.
On July 11, 2014 the Iowa Supreme Court held
that the “behind the meter” direct sale of
electricity generated from solar arrays and using
a power purchase agreement that sold the
electricity on a cents-per-kWh basis did not
automatically render the seller a “public utility.”
SZ Enterprises, LLC, d/b/a Eagle Point Solar v.
Iowa Utilities Board, ___ N.W.2d. ____ (July 11,
2014)
EPA’s Proposed 111(d) Regulations
For Existing Power Plants
• Iowa Department of Natural Resources is responsible
for Iowa’s environmental regulation.
• Board has authority over some environmental
activities by utilities. For example, Utilities’ Emission
Plan and Budget (Iowa Code Section 476.6(21)).
• Proposed 111(d) regulations affecting existing power
plants are different - These rules could have significant
adverse effects on the reliability and cost of providing
electric service.
• Also, the EPA specifically invited public utility
commissions to engage with the EPA in the
development of the proposed rules.
EPA’s Proposed 111(d) Regulations
Board Actions to Date
• Iowa Utilities Board sent comments to EPA in December 2013 on
how the regulations should be drafted.
• IUB is interested in that the final 111(d) rules are written and
implemented such that they do not:
•
•
create disruptions in the provision of electric service and;
create significant, unnecessary increases in the cost of electric service
• IUB is working jointly on comments with IDNR and Iowa Economic
Development Authority (IEDA).
• IUB is an active participant in IDNR’s 111(d) collaborative process,
and will be actively involved in the development of Iowa’s
compliance plan after the rules are final.
MISO/OMS Resource Adequacy
Survey
• MISO and OMS initiated a resource adequacy survey in
summer of 2013.
• Surveyed Load Serving Entities (LSEs) to gain better
understanding of Long-Term Resource Plans.
• Survey:
• Was a first-of-its-kind collaborative effort for MISO, LSEs and
OMS
• Sought information about all existing and future resources
• Updated demand forecasts including projected Demand Side
Management Programs
• Asked respondents to identify confidence factors for a better
understanding of certainty on LSE side
• Sought longer-term information (10 years out)
Survey Results
June 4, 2014 survey update shows:
• For MISO Resource Zone 3 (Iowa and parts of IL and MN)
• 2016 resources equal 10.1 GW
• 2016 resource requirements equal 10.6 GW
• Projected shortfall equals 0.5 GW
• For MISO North and Central Region
• 2016 resources equal 110.1 GW
•
•
•
•
2016 resource requirements equal 112.4 GW
Projected shortfall equals 2.3 GW
A shortfall figure means increased probability of a loss of load event
A 2.3 GW shortfall means approximately a .2 day/year probability of
a loss of load event, which is higher than .1 day/year industry
standard
(A projected shortfall means MISO would have to import power – not loss
of service)
Survey Future - MISO Proposal
• MISO proposes:
• continuing the survey in 2014-15 (and
potentially beyond).
• matching the survey process with the work
MISO performs as part of the Long Term
Reliability Assessment (LTRA).
• OMS will vote in October whether it continues
to serve as a survey partner
Transmission - Multi-Value Projects
(MVP Projects)
• Main purpose is to integrate growing wind power into the upper
Midwest transmission system
• Roughly 500 miles of new 345,000 volt electric transmission
circuit in Iowa alone
• 17 projects in all, four in Iowa requiring IUB approval in Iowa
• In Iowa as much as possible will be built on existing transmission
rights-of-way – often double-circuited with existing 161 kV
• Will reinforce electric transmission capacity and reliability overall
by looping the system as well as integrating wind power
Transmission - Multi-Value Projects
MVP 3 - MEC/ITC joint ownership
• MEC will construct approx. 120 miles of 345 kV line, rebuild existing 161
kV, build two new substation modify one substation – in service date is
end 2016.
• ITC will construct 145 miles in Iowa and 75 miles in MN.
• Board issued franchise for MEC’s portion of MVP 3 on August 19 for
O’Brien, Clay, Palo Alto, Kossuth, Humboldt and Webster counties
(Docket Nos. E-22106, E-22103, E-22107, E-22105, E-22104 E-22108)
• ITC has filed franchise petitions for projects in Kossuth, Winnebago,
ands Worth counties (E-22116, E-22140, E-22142, and E-22141).
