NEW YORK - Maryland picked NRG Energy Inc's Bluewater Wind subsidiary as one of three companies to supply power from renewable sources, NRG said Tuesday.

NRG Bluewater will provide up to 55 megawatts of wind generation under a power purchase agreement, which will help the state meet its renewable portfolio standard.

In 2008, Maryland Governor Martin OMalley more than doubled the state's renewable portfolio standard to require utilities to buy 20 percent of their power from clean energy sources by 2022, the company said in a release.

NRG Bluewater said it expected to get the power purchase agreement later this month from the University of Maryland.

Separately, NRG Bluewater also has a 25-year, 200 MW power purchase agreement with Pepco's Delmarva Power & Light Co utility.
