BETHESDA, Md. , June 4, 2015 (GLOBE NEWSWIRE) -- TerraForm Power, Inc. (Nasdaq:TERP), an owner and operator of clean energy power plants, today announced the acquisition of 23 MW of operating distributed solar power plants from a wholly owned subsidiary of Integrys Energy Group, Inc. , a leading energy holding company focused on regulated energy delivery in the United States . The full nameplate capacity on these 48 projects is 34 MW, with TerraForm Power's net ownership position representing 23 MW.

The solar projects are located throughout Arizona , California , Connecticut , Massachusetts , New Jersey and Pennsylvania .
