CPS Energy Forges Ahead with Western Ranch Solar Project
LCG, June 24, 2009--CPS Energy announced Monday that it executed a 20-year power purchase agreement (PPA) with Tessera Solar for the electricity generated from the 27-MW, Western Ranch Solar Project to be constructed in western Texas. The project will employ the SunCatcher power system designed and manufactured by Stirling Energy Systems (SES), an affiliate of Tessera Solar.
The SunCatcher power system consists of a parabolic dish of mirrors - spanning 40 feet across - that reflects the energy of the sun onto a receiver called a power conversion unit (PCU). The solar energy heats hydrogen gas in tubes in the PCU, and the gas passes through a heat exchanger to run a four-cylinder Stirling engine, which drives a generator to produce power.
The project will include 1,080 SunCatcher dishes, which have recently been redesigned to lower costs and ease maintenance. Construction on the project is scheduled to begin next summer, with the first units planned to commence operations by the end of 2010. The project generating capacity can be increased to 130 MW.
CPS Energy provides electric service to approximately 695,000 electric customers in and around San Antonio. Western Ranch Solar represents a big step by CPS Energy towards its commitment to develop 100 MW of solar resources and to meet 20 percent of its customers? peak electrical demand by 2020.
