TheDesert Sunlight Solar Farm is a 550-megawatt (MWAC) fixed-tiltphotovoltaic power station approximately 6 miles (9.7 km) north ofDesert Center,California,United States, in theMojave Desert[1]. It was made by the USthin-film manufacturerFirst Solar but now has split ownership betweenNextEra Energy Resources,Clearway Energy, andCalifornia Public Employee's Retirement System (CalPERS)[2][3][4]. It has the same 550-MW installed capacity as theTopaz Solar Farm in the Carrizo Plain region of Central California, making both of them tied for the secondlargest completed solar plants by installed capacity as of fall 2015.[5][6]

Project details

[edit]

The project was built on over 6 square miles (16 km2) ofcreosote bush-dominated desert habitat nearDesert Center next toJoshua Tree National Park.[7] Construction began in September 2011 and final completion was in January 2015.[6][8]

The battery storage station was completed in 2022

The Desert Sunlight Solar Farm was expanded withbattery energy storage systems (BESS) in 2022 and 2024. Desert Sunlight Battery Energy Storage System, also known as Sunlight Storage I, was the first phase of BESS that added 230 MW of 4-hour storage to the facility[9] and became operational in 2022[10]. Sunlight Storage II added an additional 300 MW of 4-hour storage the facility[11] and became operational in 2024[12]. The combined total of the two storage facilities is 530 MW of 4-hour storage, or 2,120MWh. Both storage facilities were built within the fence line of the original solar facility and therefore caused minimal new environmental impacts.[11]
