1. Technology Paper: Wind Power Group 4: Mon Arguelles Francis Estolano MumtyQuevedo Randy Prado Shine Villanueva Julienne Yee Shiela Zara

2. Wind Power Technology Paper: Wind Power

3. 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

4. Two types of wind turbines: • HORIZONTAL AXIS WIND TURBINE (HAWT) 2) VERTICAL AXIS WIND TURBINE (HAWT) Technology Paper: Wind Power

5. 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

6. GREEN TECHNOLOGY • no harmful emissions • wind – a renewable resource Technology Paper: Wind Power

7. TRENDS • ONSHORE WIND FARMS Wind farms located inland, usually in hilly or mountainous Areas. Technology Paper: Wind Power

8. TRENDS • OFFSHORE WIND FARMS • FLOATING PLATFORM CONCEPT – turbines are set on floating platforms in waters that bottom fixing is not possible. Technology Paper: Wind Power

9. 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) Technology Paper: Wind Power

10. 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. 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

12. 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

13. SWOT Analysis Threats • Government bureaucracy • Limited available technology for economical energy storage

14. Ilocos Bangui Windmills Applications • Bangui Wind Farm is a wind farm in Bangui, IlocosNorte, 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.

16. 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.

17. Cost Benefit Analysis So how much does it cost exactly? It depends. Cost is typically measured in MEGAWATT.

18. Cost Benefit Analysis For Example: Bangui Windmills Therefore, the cost is roughly $2.27M per megawatt.

19. Cost Benefit Analysis • Less than investment • cost • Estimated to be 2-3% • of total investment cost annually • Increases as Turbines • Age • Developing new turbines that last longer Maintenance Cost

20. 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

21. 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

22. Cost Benefit Analysis Annual Consumption in the Philippines in 2011 was 54,400,000,000 kWh. Common Household Items Power Use

23. Cost Benefit Analysis Benefits • 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

24. Is Wind Power a Green Energy Source? Ethical Implications Impacts to the Ecosystem • Could kill animals in flight (e.g. eagles, bats, migratory birds) • Important concern in biodiversity hotspots

25. Is Wind Power a Green Energy Source? Ethical Implications Impacts to Surrounding Communities • Sickness from noise pollution • insomnia • headaches • Devaluation of Lands • Less people could tolerate noise from wind turbines

26. Is Wind Power a Green Energy Source? Ethical Implications On Job Creation of the Industry Wind turbines are manufactured in China Maintenance of wind turbines not labor intensive

27. 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? 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.
