The 10.6MW solar project located at the Somerset solar farm in the Bexar County, Texas is using 44,280 single-axis tracking photovoltaic panels and will produce enough emission free electricity to power around 1,600 homes, according to the company.

The two partners under the New Energy Economy project have already developed two solar projects with a total generating capacity of 20MW at the Centennial Solar Farms 1 & 2 located in south Bexar County at the San Antonio Water System Dos Rios Water Recycling Center.

CPS Energy executive vice president and chief sustainability officer Cris Eugster said solar energy will be guaranteed when it is needed the most during the summer.

"So, this project further diversifies our energy portfolio and strengthens peak demand generation," Eugster added.

SunEdison was responsible for the financing and construction aspects of the projects and will operate and maintain the systems hereafter. Citi financed all the 30MW projects developed under the New Energy Economy.

CPS Energy, under a 25-year power purchase agreement, will buy all the electricity generated at the solar farms from SunEdison at fixed energy rates.
