36、ment Data,棄風(fēng)數(shù)據(jù),BPA,As of March 30, 2010, total cumulative capacity of wind that has been limited is 2900 MW.,ERCOT,In 2009, curtailed on average around 500 to 2,000 MW daily, max amount approximately 3,900 MW. ERCOT curtailed about 16% of wind generation in 2009.,Midwest ISO,In 2009, around 1,100 in
