Spanish independent power producer Grenergy Renovables has signed a 15-year, 1 TWh-per-year night-time power purchase agreement backed by its 3.5 GWh Elena battery energy storage system in Chile, the largest volume PPA the company has signed and one of the biggest battery-backed offtake deals ever inked in the Americas. Announced June 30 and reported by Energy-Storage.News on July 1, supply is scheduled to begin between July and October 2026.
Elena BESS Anchors The Oasis De Atacama Complex
Located in the Antofagasta region of northern Chile, Elena is part of Grenergy's Oasis de Atacama solar-plus-storage platform, which co-locates BESS and solar PV at multi-gigawatt scale. Elena currently spans 3.5 GWh across 624 battery containers and 6,240 battery units, with plans to double capacity to 7 GWh. Grenergy says the full Oasis de Atacama complex is on track for 2.1 GW of solar paired with 14 GWh of storage under its 2028 strategic roadmap. The project was inaugurated in June with Chile's President José Antonio Kast Rist and Energy Minister Ximena Rincón in attendance.
Nighttime Dispatch, 15-Year Contract
The 1 TWh annual supply is delivered at night, monetising cheap midday solar generation charged into the batteries and dispatched into the evening peak. Grenergy has previously ordered 2,600 MWh of BESS equipment from BYD for a separate Central Oasis complex in Chile, and in May sold three solar-plus-storage projects (including Victor Jara and the two Quillagua phases) to ContourGlobal — repositioning around Elena and Oasis de Atacama as its flagship LATAM asset.
Chile Emerges As A Utility-Scale BESS Powerhouse
Elena's 3.5 GWh figure eclipses the BESS portion of the 2024 Edwards & Sanborn solar-plus-storage project in California (3,287 MWh), making it the largest single battery plant in the Americas. Chile has become a favoured destination for dispatchable renewables thanks to Atacama's world-class solar resource and a wholesale market that pays a premium for evening supply.
