Offshore Wind Market – Europe

• 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%

• f 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.

• U.S

. Department of Energy (DOE) report 20% Wind Energy by 2030 included 54 GW offshore t o accomplish that goal.

• DOE recently announced A National Vision and Call to

Action for creating a U.S . offshore wind industry.

• $100M allocated to offshore wind research and test

facilities through the American Reinvestment and Recovery Act.

• RI and NJ completed competitive processes for

proposed proj ects.

• A DE utility has signed a ratified Power Purchase

Agreement (PPAs) with a developer. PPAs have been signed in MA and RI as well.

• NJ passed t he Offshore Wind Economic Development

Act, providing for energy certificates, tax credit s, and financial incentives

• S

ignificant interest in t he Great Lakes, including competively-bid RFPs for a pilot project in OH and utility-scale project in NY.

• First federal lease signed for proj ect in MA, under

preliminary leasing process.

• Federal leasing process initiated off of DE and

anticipated to begin near-t erm for proj ects off the coast of MD and VA.
