EPRI Announces Solar Thermal Hybrid Demonstration Projects

LCG, December 4, 2009--The Electric Power Research Institute (EPRI) yesterday announced plans for two solar thermal hybrid projects that will demonstrate how solar energy can be integrated into existing power stations to reduce carbon emissions.

Solar energy will be concentrated and used to generate steam for use in a steam turbine for power generation. The solar energy will reduce fossil fuel necessary for power generation during the day. The solar thermal hybrid approach provides for a cost-effective, reliable, dispatchable power generation facility that includes the use of solar energy. Moreover, the hybrid solution offers the potential to reduce carbon emissions per unit electricity generated from existing power stations.

One demonstration project will be at the Escalante Generating Station, a 245-MW coal-fired station in Prewitt, New Mexico that is owned by Tri-State Generation and Transmission Association, Inc. The other project will occur at the Chuck Lenzie Generating Station, a 1,102-MW gas-fired facility located near Las Vegas and owned by
NV Energy.

EPRI, the plant owners and operators, and other participants have formed collaboratives to develop and provide data from these solar projects to the industry and public. The collaboratives will support the hosts in selecting the integration design, and conduct independent plant performance monitoring, evaluation and economic assessments of their planned projects.

Both Nevada and New Mexico have Renewable Portfolio Standards.
