Abengoa Solar to build first solar thermal installation integrated with a coal plant

The demonstration project is intended to increase power plant efficiency while lowering carbon emissions and is the first time that solar energy will be used to increase the efficiency and lower the emissions of a coal power plant in the United States.

Abengoa Solar has been selected by Xcel Energy, Colorado’s largest electric utility company, to build a demonstration parabolic trough concentrating solar power CSP plant at its Cameo coal plant near Grand Junction, Colorado (US). The project is the first to integrate an industrial solar installation into a conventional electrical power plant.

Construction is expected to start within a month and the plant is expected to be operational by the end of the year. The project, awarded to Abengoa Solar by Xcel, is the first project under an Innovative Clean Technology program that has been approved for Xcel Energy by the Colorado Public Utilities Commission.

The goal of the project is to prove that the heat produced by a solar facility can increase the efficiency of a conventional power plant while also lowering carbon dioxide emissions. Successful integration of this technology may enable future large-scale applications of this technology into other power plants.

"We continue to move forward in developing ways to help us reduce our impact on the environment," said David Wilks, President of Energy Supply for Xcel Energy. "If this demonstration works, we may be able to implement this type of technological advance in other coal-fired power plants to help further reduce carbon dioxide emissions in Colorado and possibly other areas of our service territory."

This four thermal megawatt solar installation will use state-of-the-art parabolic trough collectors developed by Abengoa Solar.

Ken May, Director of Abengoa Solar IST, emphasized the high potential of large-scale applications of the industrial solar installation technology: "Proper use of the solar thermal energy produced at these facilities can improve plant efficiency while lowering carbon dioxide emissions. The successful integration of solar and coal technologies will encourage more widespread use throughout the utility sector."
