Colorado Integrated Solar Project
Xcel Energy’s first Innovative Clean Technology project is a concentrating solar plant integrated with a conventional coal-fired power plant. Located at our Cameo Generating Station near Palisade, Colo., the project is the world’s first known demonstration of the hybrid solar-coal approach using parabolic-trough solar technology. The system is concentrating solar energy that provides heat to produce supplemental steam for power generation at Cameo Station's Unit 2 and promises to:
- decrease the overall consumption of coal,
- reduce emissions from the plant,
- improve plant efficiency,
- test commercial viability of concentrating solar integration, and
- increase the opportunity for cost-effective renewable power generation.
