The Department of Energy announced December 17 $20 million in new funding for two to four projects to integrate concentrating solar power systems with fossil fuel power plants. The hybrid systems leverage the infrastructure of fossil fuel plants, helping to reduce the cost of solar electricity and bring CSP plants online more quickly. Currently, between 11 and 21 GW could be built and integrated into existing plants in the country, enough to power between 3 and 6 million homes.
