Can we meet this goal?
• Land-based wind energy has grown at a 30% annual growth rate over the past five years
• Achieving 54 GW by 2030, would require offshore to grow at a 23% annual growth rate (avg. 3,375 MW/year) assuming 2,000 MWs are installed by 2014

Wind resource and proximity to load
• Close proximity to large and growing load centers along eastern seaboard
• Lack of high wind, land-based sites in Northeast
• Strong correlation between production and peak loads

State and federal policies resulting in higher fossil fuel
costs
• RGGI – 10 states signed MOU– First auction in September
• National cap and trade legislation likely in 2009
• Debate shifting from causes of global climate change to solutions

Growing state RPS requirements
• Delaware 20% by 2019• Maryland 20% by 2022• New Jersey 22.5% by 2021• Pennsylvania 18% by 2020/2021– Over 20 million MWh’s by 2020 in DE, MD, NJ,
and PA combined• New York 24% by 2013• Rhode Island 16% by 2020

Offshore wind park development• Identify site– Wind resource ≥ to 18 mph– Moderate water depths & suitable sea floor
conditions– Minimal conflicts over ocean use– Compatibility with other environmental goals– Access to electric transmission– Ports available for construction and O&M

Offshore wind park development continued
• Engage the public early and often– Identify all stakeholders– Educate, educate, educate– Honest and transparent communication– Visualizations play a critical role

What’s needed to advance offshore wind energy in the
U.S.• Federal policies– Short Term - stable production incentive (PTC)– Mid Term - national RPS and transmission legislation– Long Term - effective carbon regulation
• Continued refinement of technology• Fair lease and operating fees for a
nascent industry
