--ConEdison Development, A Nationally Prominent Renewable Energy Developer, Assumes Responsibility for Alamo 3--

SAN ANTONIO – February 19, 2015: Alamo 3, the latest solar facility developed as part of a 400-MW solar project between CPS Energy and OCI Solar Energy, is now in commercial operation. The new photovoltaic solar installation provides 5.5-megawatts of renewable power to CPS Energy customers in the San Antonio area, enough to power approximately 1,300 homes for a year.

Consolidated Edison Development, a New York State-based developer and operator of large-scale renewable energy projects, assumed responsibility for the 5.5-megawatt farm earlier this month.

CPS Energy, through power purchase agreements with operators like ConEdison Development, has 134 megawatts of solar generation capacity – the most in Texas.

"The launch of Alamo 3 represents another milestone in renewable energy development for our customers. It also supports technologies that protect our environment and boost local economic development," said CPS Energy Executive Vice President Cris Eugster. "We look forward to a long partnership with ConEdison Development, which has a reputation as one of the country's most successful and reliable renewable developers."

"Through its growing commitment to renewable energy, CPS Energy is emerging as a role model for municipally owned utilities nationwide," said Mark Noyes, senior vice president and chief operating officer of ConEdison Development. "As our company steadily expands our national renewable portfolio, it is a privilege to help deliver clean and environmentally benign power supplies to the people of Greater San Antonio."

The solar facility will deliver electricity to CPS Energy under a 25-year power purchase agreement.
