​CH Energy Group Divests Shirley Wind Farm

CH Energy Group, Inc. (NYSE: CHG) subsidiary Central Hudson Enterprises Corporation has sold the 20MW Shirley Wind Farm facility in Glenmore, Wisconsin,
to DEGS Wind I, LLC, a subsidiary of Duke Energy Corporation. The closing took place on August 11, 2011. The wind project was first acquired by CH
Energy Group in 2009.

“This divestiture is consistent with CH Energy Group’s strategy,” said Chairman of the Board, President and C.E.O. Steven V. Lant. “Proceeds available
to CH Energy Group from this sale are anticipated to repay approximately $20 million in outstanding CH Energy Group debt and repurchase common stock,”
he said.

“After including the financial effect of the early debt retirement, this transaction is expected to result in a modest gain,” Lant added.

Morrison & Foerster served as legal counsel and Marathon Capital as financial advisor to
CH Energy Group.
