Example Offshore Wind Park Layout Slide 2
Offshore Wind Works By the Numbers 9 countries with completed offshore wind parks 16 wind parks under-construction (during Q1 & Q2 2010) 43 completed offshore wind parks 830 wind turbines installed (by year-end of 2009) 1991 year of first offshore wind installation 2396 MW of total installed capacity (as of June 2010) 3972 MW of capacity under-construction (during Q1 & Q2 2010) 34000 MW of capacity awarded in UK “ Round 3” Slide 3
Offshore Wind Market – Europe European Market Projection 2009 EWEA Report “ Oceans of Opport unit y” over 100 GW planned Oceans of opportunity • Europe’ s offshore wind potent ial is enormous and able to power Europe seven times over. • Huge developer interest Over 100 GW of offshore wind proj ects are already in various stages of planning. If realized, these proj ects would produce 10% of the European Union’ s electricity. Repeating the onshore success • EWEA has a target of 40 GW of offshore wind by 2020, an average annual market growth of 28% . The EU market for onshore wind grew an average 32% per year from 1992-2004. Source: EWEA Slide 4

Offshore Wind Market – United States U.S. Offshore Wind U.S. Offshore Wind Projects (Ocean) Industry Highlights • U.S . Department of Energy (DOE) report 20% Wind Project State Size in MW Energy by 2030 included 54 GW offshore t o accomplish that goal. Cape Wind MA 468 • DOE recently announced A National Vision and Call to Hull Municipal MA 15 Action for creating a U.S . offshore wind industry. Rhode Island RI 379 • $100M allocated to offshore wind research and test facilities through the American Reinvestment and New York Power Authority NY 700 Recovery Act. • RI and NJ completed competitive processes for New Jersey BPU NJ 1050 proposed proj ects. Bluewater Wind DE 450 • A DE utility has signed a ratified Power Purchase Agreement (PPAs) with a developer. PPAs have been S outhern Company GA 10 signed in MA and RI as well. W.E.S .T. TX 300 NJ passed t he Offshore Wind Economic Development • Act , providing for energy certificates, tax credit s, and TOTAL 3372 financial incentives “ …we are est ablishing a program t o aut horize…t he leasing • S ignificant interest in t he Great Lakes, including competively-bid RFPs for a pilot project in OH and of federal wat ers for proj ect s t o generat e elect ricit y from wind …t his will open t he door t o maj or invest ment s in utility-scale project in NY . offshore clean energy …t here is enormous int erest in wind First federal lease signed for proj ect in MA , under • proj ect s off t he coast s of New Jersey and Delaware, and preliminary leasing process. t oday’ s announcement will enable t hese proj ect s t o move Federal leasing process initiated off of DE and • forward.” anticipated to begin near-t erm for proj ects off the President Barack Obama, April 22, 2009 coast of MD and VA .
