Renewables replacing coal.
On Wednesday, the Public Utilities Commission of Nevada approved NV Energy’s Integrated Resource Plan, which would add 1,190 megawatts of solar renewable energy projects to the state, as well as an additional 590 megawatts of energy storage capacity.
The Arrow Canyon Solar Project, a 200-megawatt solar photovoltaic project with a 75-megawatt battery storage system, is set to be located 20 miles northeast of Las Vegas on the Moapa Band of Paiutes Indian Reservation. A second project — the Southern Bighorn Solar & Storage Center, is a 300-megawatt solar array with a 135-megawatt Li-Ion battery energy storage system — is set to be built on the Moapa River Indian Reservation about 30 miles north of Las Vegas. And the Gemini Solar and Battery Storage Project, a 690-megawatt solar photovoltaic array with a 380-megawatt AC battery storage system, is set to be built on about 7,100 acres of federally owned land 25 miles northeast of Las Vegas.
These projects will replace the generation that NV Energy used to get from its partial ownership - 255 MW - of the recently closed Navajo power plant. NV still has partial ownership - 260MW - of the Valmy coal plant in Northern Nevada. Both units at Valmy will be closed by 2025.
Going forward, renewables in Nevada will also increasingly replace Natural Gas generation. NG generation in NV paeked in 2015 and has already begun a slow decline. Expect that decline to accelerate.
