1 WIGTON WINDFARM LIMITED Climate Change Adaptation and Disaster Risk Reduction (CCADRR) Project Public Awareness Campaign and Celebration of World Meteorological DayMeteorological Day 2012 March 23, 2012 Presenter: Michelle Chin Lenn Project Manager

2 AGENDA Experiences of Wigton Windfarm since its inception Role and possible future for alternative energy sources in the island s energy mix

3 JAMAICAN ENERGY SCENARIO Liberalised Generation Market Monopoly on Transmission and Distribution Heavy Reliance on Imported Fossil Fuels High exposure to price volatility ~94% - Oil Based Electricity Generation Electricity Grid 859 MW installed 64.3 MW Renewables (Wind & Hydro) 7.4% Renewables by installed capacity

4 JAMAICAN ENERGY SCENARIO Wind is 2.7% of annual electricity generation Hydro is 3.4% of annual electricity generation From MW total installed From 22.4 MW total installed 3 wind farms 7 Hydro Plants Munro Less than 5 MW each Wigton I & Wigton II

6 FRAMEWORK FOR RENEWABLES Policy Targets: 1995 Energy Policy followed by National Energy Policy: Diversification of fuels Development of renewable energy resources Increase Jamaica's renewable energy use from ~6.1% in 2009 by MWh to 11% by % by % by % by 2030 now revised to 30% Current Renewable Energy Pricing Framework: Avoided cost + up to 15% premium i.e. up to US cents/ kwh for energy without capacity

7 Petroleum Imports decreasing Down 33% since 2006 Main factor bauxite down due to energy costs Data Source: Ministry of Energy and Mining 2011

9 BENEFITS OF RENEWABLE ENERGY Environmentally friendly generation No dust fly ash nitrous and sulphur oxides (acid rain) greenhouse gases Energy Diversification and Security Reduce expenditure on imported fuel Saves foreign exchange Change from unpredictable fuel pricing to regular, predictable capital repayment for the country and consumer Training and development in new industry

10 Is Jamaica on Track for meeting Renewable Energy Targets?

11 IDENTIFIED RENEWABLE ENERGY PROJECTS Type Entity Size (MW) Projected MWh Location Wind JPS ,990 52,560 Munro Wind Wigton III & IV ,072 78,840 Manchester Wind CAEL 24 63,072 Manchester WtE PCJ ,000 Riverton WtE PCJ ,000 Retirement Hydro JPS ,500 Maggotty Hydro PCJ , ,360 Various Biomass Ministry/PCJ ,000 Duckenfield Biomass Ministry/PCJ ,350 Frome Total WtE Waste to Energy Up to MW Up to 1,169,682MWh

12 1,169,682 MWh from RE represents 28.3% of 2010 Electricity Generation Significant RE potential Exceeds 20% target for 2030 if all projects implemented But many technologies are new to Jamaica eg. WtE versus wind where there is capacity and experience Thus Wigton could play a vital role in implementing additional wind projects eg. Wigton III North Wigton, Wigton IV at Munro

13 EG. RECENT WIND PROJECTS POTENTIAL BENEFITS FOR JAMAICA WIND FARM CAPACITY (MW) PROJECTED OUTPUT (GWh/ yr) BARRELS OF OIL AVOIDED (Bbl/ yr) BARRELS OF OIL FOREIGN EXCHANGE SAVINGS $90/ bbl) (US$) GHG EMISSIONS AVOIDED (tonnes CO 2 ) POTENTIAL CARBON CREDITS REVENUE(@ min. 5.5 / CER) (US) Wigton I Wigton II ,000 2,879,979 45, , ,826 2,504,329 39, ,437 JPS Wind , ,388 6,575 46,073 Annual Benefit ,463 5,801,696 91, ,412

14 WIND ENERGY Radiation from the sun heats up various sections of the earth at different rates and at varying times This differential heating gives rise to differential pressure in the atmosphere Hot air rises and cool air rushes into its place resulting in wind When the wind hits the rotor of a wind turbine some of the wind energy is converted into blade rotation, after which the wind speed drops behind the rotor (hub + blades) The wind turbine transforms this rotation into electrical energy

15 WIND ENERGY DEVELOPMENTS On-shore vs Off-shore Wind Projects: % Cost Breakdown Off-shore Civil and Electrical costs higher than onshore Planning & Development Electrical & Grid Connection Civil/ Foundations Wind Turbines ~US$ 2.5 M/ MW On shore ~US$ 5.0 M/ MW Off shore

16 WIND COSTS Fuel cost to the consumer alone exceeds Wigton s wind energy sale price therefore it is a myth that wind energy costs the consumers more. For 2010, fuel costs = US cents/ kwh Which is higher than: Wigton I price US$ cents/ kwh Wigton II price US$ cents/ kwh JPS Castalia 2011 study & MEM 2011 paper recommended wind price US$ 15 cents/ kwh

32 Wigton should continue to be a market player to play a strategic role in achieving Energy Policy Goals 2,3,4,5 Goal 2: Jamaica has a modernized and expanded energy infrastructure that enhances energy generation capacity and ensures that energy supplies are safely, reliably, and affordably transported..on a sustainable basis Goal 3: Jamaica realizes it energy resource potential through the development of renewable energy sources and enhances its international competitiveness, energy security whilst reducing its carbon footprint Goal 4: Jamaica s energy supply is secure and sufficient to support long-term economic and social development and environmental sustainability Goal 5: Jamaica has a well-defined and established governance, institutional, legal and regulatory framework for the energy sector, that facilitates stakeholder involvement and engagement

33 TARGETED WIND SITES North of Wigton (Newlands) Munro Great Valley Wind speed map at 70 m elevation

34 CONCLUSION Wigton has built human and infrastructural capacity Excellent Operational Record Poised to make contribution with development of at least another 2 wind farms With proper renewable tariffs, projects can be implemented and renewable energy targets met
