Background

WIND TURBINESstructures 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 farmRoscoe Wind Farm in Roscoe,

Texas

Two types of wind turbines:

1) HORIZONTAL AXIS WIND TURBINE (HAWT)

2) VERTICAL AXIS WIND TURBINE (HAWT)

SWOT Analysis

Strengths

Free, renewable resource

No harmful emissions

No need to purchase fuel

Minimal operating and

maintenance (O&M)

expenses

Minimal land use


11/28

SWOT Analysis

Weaknesses

High cost of initial investment

Wind supply may be unreliableand can only be used in supportof existing electric grids

Can only be located in

uninhabited areas Can produce noise at

uncomfortable levels


12/28

SWOT Analysis

Opportunities Philippines location in the

monsoon belt results to

several potential wind farmlocations

Expansion resulting from theinclusion of the RE sector in

the Investment PrioritiesPlan (IPP)

Growth from developmentof small-scale wind turbines

SWOT Analysis

Threats

Government bureaucracy

Limited available

technology for economical

energy storage

Applications

Bangui Wind Farmis 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-kilometershoreline off Bangui Bay, facing the South

China Sea.

Cost Benefit Analysis

The planning of a wind farm

Its never just one windmill.

Steps:

1. Set target powerrequirement.

2. Canvas Turbine Costs.

3. Identify a geographical area4. Negotiate Construction Bid.

5. Build.


17/28


So how much does it cost

exactly?

It depends.

Cost is typically

measured in

MEGAWATT.


18/28


For Example: Bangui Windmills

Therefore, the cost isroughly $2.27M per

megawatt.


19/28


Maintenance Cost

Less than investmentcost

Estimated to be 2-3%of total investment costannually

Increases as TurbinesAge

Developing new turbinethat last longer


20/28


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 Meralcos

Rate of roughly Php6.67/kWh


21/28


What this costs could mean to you:For example:

Use Macbook Pro 35Hours a week.

30watts x 35hrs/wk x52wks/yr

= 54,600 watts/hr or 54.6kWh

Cost: (Meralco)54.6 kWh x 6.67 = Php364.18

(Wind)54.6 kWh x 4.47 = Php244.06

Cost Benefit AnalysisCommon Household Items Power Use

Annual Consumption in the

Philippines in 2011 was

54,400,000,000 kWh.


23/28


Estimated savings of .07centavos for every kilowatt-

hour produced against fossilfuel power

Will help an estimatednumber of 70, 000

household Reduced CO2 emission by

56,788 of CO2 per year

Reduced risk of respiratory

problem

Ethical ImplicationsIs Wind Power a Green Energy Source?

Impacts to the Ecosystem

Could kill animals in flight(e.g. eagles, bats,

migratory birds)

Important concern inbiodiversity hotspots


25/28


Impacts to Surrounding

Communities

Sickness from noisepollution

insomnia

headaches

Devaluation of Lands

Less people could tolerate

noise from wind turbines


26/28


On Job Creation of the

Industry

Wind turbines are

manufactured in China

Maintenance of windturbines not labor intensive

27/28

Nation-Building

Implications

Seeing that wind farms could only be put up instrategic 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.

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?
