Indigo Energy Facility

North Palm Springs, CA

The Indigo Energy Facility is a 136-megawatt (MW), natural gas, simple-cycle electric peaking generating station. Located in North Palm Springs, CA in an area dominated by wind turbines, Indigo was the third facility to be licensed under the California Energy Commission’s emergency siting process instituted to expedite electricity plants that could be online by September 30, 2001. Indigo was sited, licensed and constructed within just six months to answer California’s urgent need for electricity during peak periods.

Indigo utilizes a combination of fast-start capability and rapid ramp rates to meet California’s growing peaking requirements especially during the sunset ramp hours. Using clean-burning natural gas, the plant employs water injection NOx control technology to reduce emissions. Indigo’s site was chosen for its proximity and access to existing natural gas and electric transmission lines. In order to avoid impacting the local infrastructure, the zero-discharge facility draws and purifies any water it requires from its on-site well.

DGC Management, LLC is the Asset Manager providing asset management services; and DGC Operations, LLC serves as the Operator providing O&M services for Indigo. The facility is powered by three General Electric (GE) LM6000 PC Sprint combustion turbines generators, which employ Best Available Control Technology to limit emissions and noise.
