CPS Energy awards EPC contract to RES for its 5 MW solar project in Texas

Renewable Energy Systems (RES), has been selected by CPS Energy to construct an innovative solar and energy storage project to be located at 9800 W. Commerce in San Antonio, Texas. RES was selected through a competitive request for proposal (RFP) and has been awarded the engineering, procurement, construction, and maintenance of the facilities. Construction will begin in October 2018 with commercial operation in May 2019.

The CPS Energy solar and energy storage systems consist of 5 MWAC of distributed solar capacity co-located with a 10 MW/10 MWh RESolve lithium-ion Battery Energy Storage System (BESS). This project takes an innovative approach in combining distributed solar generation with strategically sized and configured electrochemical energy storage, with both technologies interconnected at distribution voltage on a common feeder. Once operational, the system will allow for peak mid-day solar production to be stored and injected onto the grid in late afternoon and early evening, resulting in reduced reliance of fossil fuel generators to meet peak demand during these periods. This represents a scalable approach to meeting peak system electrical demand with lower emissions and increased flexibility.
