Technology Paper: Wind Power
 Wind Power
Technology Paper: Wind Power
 Background
 WIND TURBINES – structures that harness the energy from
the wind by converting its kinetic energy into mechanical
and electrical energy.
 Grouped into WIND FARMS, which are either onshore or
offshore.
 Largest on shore wind farm – Roscoe Wind Farm in Roscoe,
Texas
Technology Paper: Wind Power
 Two types of wind turbines:
1) HORIZONTAL AXIS WIND TURBINE (HAWT)
2) VERTICAL AXIS WIND TURBINE (HAWT)
Technology Paper: Wind Power
 A WIND TURBINE’S DESIGN:
•WINGS - like an airplane’s propeller
•WEATHER VANE at the shaft –
connected to the computer which
controls the velocity of blades
•GEARS LOCATED INSIDE THE SHAFT –
Big gears help increase the velocity
Of the blades
Technology Paper: Wind Power
 GREEN TECHNOLOGY
 no harmful emissions
 wind – a renewable resource
Technology Paper: Wind Power
 TRENDS
• ONSHORE WIND FARMS
Wind farms located inland,
usually in hilly or mountainous
Areas.
Technology Paper: Wind Power
 TRENDS
• OFFSHORE WIND FARMS
• FLOATING PLATFORM CONCEPT –
turbines are set on floating
platforms in waters that
bottom fixing is not
possible.

 Lightning measurement and impact
detection system
 Advanced sensor technologies
 Condition monitoring system (CMS)
 Fault Detection System (FDS)
SWOT Analysis
Strengths
•
•
•
•
Free, renewable resource
No harmful emissions
No need to purchase fuel
Minimal operating and
maintenance (O&M)
expenses
• Minimal land use
SWOT Analysis
Weaknesses
• High cost of initial investment
• Wind supply may be unreliable
and can only be used in support
of existing electric grids
• Can only be located in
uninhabited areas
• Can produce noise at
uncomfortable levels
SWOT Analysis
Opportunities
• Philippines’ location in the
monsoon belt results to
several potential wind farm
locations
• Expansion resulting from the
inclusion of the RE sector in
the Investment Priorities
Plan (IPP)
• Growth from development
of small-scale wind turbines
SWOT Analysis
Threats
• Government bureaucracy
• Limited available
technology for economical
energy storage
Applications
Ilocos Bangui Windmills
• Bangui Wind Farm is a wind
farm in Bangui, Ilocos Norte, Philippines.
The wind farm uses 20 units of 70-metre
(230 ft) high VestasV82 1.65 MW wind
turbines, arranged on a single row
stretching along a nine-kilometer
shoreline off Bangui Bay, facing the South
China Sea.
Applications
Mobile House

Cost Benefit Analysis
The planning of a wind farm
It’s never just one windmill.
Steps:
1. Set target power
requirement.
2. Canvas Turbine Costs.
3. Identify a geographical area
4. Negotiate Construction Bid.
5. Build.
Cost Benefit Analysis
So how much does it cost
exactly?
It depends.
Cost is typically
measured in
MEGAWATT.
Cost Benefit Analysis
For Example: Bangui Windmills
Therefore, the cost is
roughly $2.27M per
megawatt.
Cost Benefit Analysis
Maintenance Cost
•Less than investment
cost
•Estimated to be 2-3%
of total investment cost
annually
•Increases as Turbines
Age
•Developing new turbines
that last longer
Cost Benefit Analysis
For Example: Bangui Windmills
(cont..)
• Operated by Transco Laoag
• Estimated 21 year life
• Sells power to INEC for Php4.43 / kWh
under
Electricity Sales Agreement
• This price already includes both
maintenance and investment cost
• Consider this price versus Meralco’s
Rate of roughly Php6.67/kWh
Cost Benefit Analysis
What this costs could mean to you:
For example:
Use Macbook Pro 35
Hours a week.
30watts x 35hrs/wk x
52wks/yr
= 54,600 watts/hr or 54.6
kWh
Cost:
(Meralco)
54.6 kWh x 6.67 = Php364.18
(Wind)
54.6 kWh x 4.47 = Php244.06
Cost Benefit Analysis
Common Household Items Power Use
Annual Consumption in the
Philippines in 2011 was
54,400,000,000 kWh.
Cost Benefit Analysis
Benefits
• Estimated savings of .07
centavos for every kilowatthour produced against fossil
fuel power
• Will help an estimated
number of 70, 000
household
• Reduced CO2 emission by
56,788 of CO2 per year
• Reduced risk of respiratory
problem
Ethical Implications
Is Wind Power a Green Energy Source?
Impacts to the Ecosystem
• Could kill animals in flight
(e.g. eagles, bats,
migratory birds)
• Important concern in
biodiversity hotspots
Ethical Implications
Is Wind Power a Green Energy Source?
Impacts to Surrounding
Communities
• Sickness from noise
pollution
– insomnia
– headaches
• Devaluation of Lands
– Less people could tolerate
noise from wind turbines
Ethical Implications
Is Wind Power a Green Energy Source?
On Job Creation of the
Industry
Wind turbines are
manufactured in China
Maintenance of wind
turbines not labor intensive
Nation-Building
Implications
The benefit in investing on wind energy for the
environment is quite obvious.
Having this kind of renewable energy would definitely be
advantageous for the environment. But when a country,
the Philippines in this case, shifts to this new kind of
renewable technology, how would it affect growth of the
country?
•
Seeing that wind farms could only be put up in
strategic places in the country, these provinces
and other provinces surrounding it would have
more opportunities.
•
This will provide the local community will more
jobs and a means of livelihood.
•
Opening such wind farms to these provinces
will provide both white collar and blue collar
work opportunities.
