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, TexasSlide4

Technology Paper: Wind Power

Two

types of wind turbines

:

HORIZONTAL AXIS WIND TURBINE (HAWT)2) VERTICAL AXIS WIND TURBINE (HAWT)Slide5

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 velocityOf the bladesSlide6

TRENDS

ONSHORE WIND FARMS

Wind farms located inland,

usually in hilly or mountainous

Areas.Slide8

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.Slide9

SWOT Analysis

Strengths

Free, renewable resource

No harmful emissions

No need to purchase fuel

Minimal operating and maintenance (O&M) expenses

Minimal land useSlide11

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 levelsSlide12

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 turbinesSlide13

SWOT Analysis

Threats

Government bureaucracy

Limited available technology for economical energy storageSlide14

Applications

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.

Cost Benefit Analysis

The planning of a wind farm

It’s never just one windmill.

Steps:

Set target power requirement.

Canvas Turbine Costs.

Identify a geographical area

Negotiate Construction Bid.

Build.Slide17

Cost Benefit Analysis

So how much does it cost exactly?

It depends.

Cost is typically

measured in MEGAWATT.Slide18

Cost Benefit Analysis

For Example: Bangui Windmills

Therefore, the cost is roughly $2.27M per megawatt.Slide19

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 longerSlide20

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/kWhSlide21

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 = Php244.06Slide22

Cost Benefit Analysis

Common Household Items Power Use

Annual Consumption in the Philippines in 2011 was 54,400,000,000 kWh.Slide23

Cost Benefit Analysis

Estimated savings of .07 centavos for every kilowatt-hour 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

BenefitsSlide24

Ethical Implications

Is

Wind Power a

Green Energy Source?

Impacts to the Ecosystem

C

ould kill animals in flight (e.g. eagles, bats, migratory birds)

Important concern in biodiversity hotspotsSlide25

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 turbinesSlide26

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 intensiveSlide27

Nation-Building Implications

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.

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?Slide28
