Korkia advances Chilean storage pipeline across two projects for 1.55 GWh

A 750 MWh standalone battery energy storage system (BESS) dubbed the Beltrán project, located in the Valparaiso region, has reached ready-to-build (RTB) status. The standalone system, situated close to the La Pólvora substation, is being developed by Korkia in partnership with Solar Ray.

Korkia also confirmed progress on its Mellizas hybrid project, a 218 MW solar power plant with a co-located 800 MWh BESS. Mellizas has received environmental approval, enabling the company to proceed to the next phases of development.

Developed along with its Chilean development partner Ciudad Luz, Mellizas will cover approximately 300 hectares, with Korkia claiming it will be “one of the largest solar PV developments in Pemuco in the Ñuble region.”

“These milestones reflect the tangible progress we are making in Chile, advancing projects through key development and de-risking stages. Mellizas and Beltran also demonstrate the strategic role that energy storage will play in building a more flexible and resilient energy system and enabling the continued growth of renewable energy in the country,” said Rodrigo Ackermann, vice president LatAm​ at Korkia.

In August 2026, Korkia and joint venture partner Semecon sold their 125 MW Kukonkyla BESS project in Finland to Enlight Renewable Energy.  It was also granted a grid permit for 550 MW project in Romania.

Korkia’s renewable energy pipeline spans 15 GW of mature utility-scale solar, wind and BESS assets, with a further 9 GW progressing through early-stage development in Europe, North America, and South America.

Earlier this year, Solar Ray received environmental approval for its 150 MW / 750 MWh Paicavi BESS.
