Colorado Integrated Solar Project

The Colorado Integrated Solar Project is a hybrid CSP/coal plant approach using parabolic-trough solar technology. A parabolic trough solar field provides thermal energy to produce supplemental steam for power generation at Xcel Energy's Cameo Station's Unit 2 (approximately 2MWe equivalent) in order to decrease the overall consumption of coal, reduce emissions from the plant, improve plant efficiency, and test the commercial viability of concentrating solar integration.
