Profile

Grid role: Solar-plus-storage energy shifting and renewable firming: the battery stores solar energy generated during the day and delivers it to the grid when customers need it.
Context: Clean Power Alliance described High Desert as one of its first projects using battery technology: the battery stores solar energy generated during the day and delivers it to the grid when customer demand is highest. Goldman Sachs described the facility as its first internally built solar-plus-storage project.
Physical build: Ground-mounted 100 MW solar PV facility with 50 MW energy storage capacity, comprising 295,344 solar panels and 321 battery cubes. Ingeteam supplied 123 power stations rated at 3.28 MVA; each includes two solar PV inverters, one 3.3 MVA medium-voltage transformer, an auxiliary-services transformer, and a low-voltage panel.
