· Repower the company’s Mandalay facility in Oxnard with 262 MW of newer, more flexible and efficient natural gas generation under a 20-year PPA with SCE
· Install 178 MW of “preferred resources” that include both demand response and energy efficiency products to be deployed under long-term contracts at sites across Southern California
· Develop a two megawatt-hour battery energy storage system
The repowering of Mandalay is designed to ensure continued reliability and to help integrate renewable energy into the grid and will also involve the removal the two large steam units at the site, enhancing the coastal viewshed. The repowered Mandalay units are expected to come online in 2020.
The Mandalay repowering project complements NRG’s 600 MW Carlsbad Energy Center, in which NRG will remove the five steam units at its existing site in Carlsbad, California and replace them with smaller, flexible, fast start peaking units.
The Carlsbad Energy Center is expected to help integrate renewables into the grid, eliminate once-through cooling, and result in a reduced environmental and visual profile. The Carlsbad Energy Center is expected to come online in late 2017, and is awaiting CPUC approval of a 20 year PPA with SDG&E.
These contracts follow a string of successful projects that have helped bring more renewable power to California through solar and wind generation backed up by new flexible gas generation. NRG, individually or through its unit NRG Yield, Inc., owns the 720 MW Marsh Landing, 550 MW El Segundo and 500 MW Walnut Creek power plants that all have fast start capabilities, allowing them to come online quickly when renewable power decreases.
In addition, NRG Yield owns the nation’s largest wind farm, located in California. Through both NRG and NRG Yield, the companies provide more than a thousand megawatts of solar to the state from numerous large and small solar arrays, including the world’s largest concentrated solar thermal project.
NRG has transformed Levi’s Stadium in Santa Clara into a solar generator that can power a season of NFL home games. The company also operates the eVgo network which has completed installation on more than 85 DC fast chargers to support California’s 100,000 electric vehicles and is retrofitting eVgo electric vehicle charging sites to be compatible with the new DC fast charger standard being used by the BMW i3, Chevrolet Spark and Volkswagen eGolf. DC fast chargers can charge most electric vehicles to 80 percent of full charge in 30 minutes or less.
