150 MW BESS project in Chile receives environmental approval

The Chilean Metropolitan Region Environmental Assessment Commission has approved the Environmental Impact Declaration (DIA) for the 150 MW / 750 MWh Paicaví battery energy storage project, marking a new milestone for Korkia Solar Ray, a joint development company between Korkia and Solar Ray.

BESS Paicaví is a utility-scale battery energy storage system designed to enhance the efficiency and flexibility of the power system by storing electricity during periods of surplus generation and dispatching it back to the grid when needed. Located in La Pintana in the Santiago Metropolitan Region, the project will be developed near CGE Transmisión’s Mariscal Substation, the planned point of interconnection.

Following environmental approval, Korkia Solar Ray will continue advancing the project toward construction readiness, including final technical and interconnection-related steps.

Scaling battery storage to address grid constraints

As renewable capacity expands in Chile, transmission constraints have led to increasing curtailment of solar and wind generation. To address this, the country is rapidly scaling up battery storage.

As of mid-2025, approximately 1.7 GW of storage was connected to the grid (1 GW operational and 0.7 GW in testing), with a further 4.8 GW under construction or declared, according to Revista Nueva Minería & Energía (October 2025). Chile’s 2 GW storage target for 2030 is expected to be reached well ahead of schedule, underscoring the pace of market development.

Advancing a growing renewable and storage portfolio in Chile

Korkia entered the Chilean market in 2023 through partnerships with Ciudad Luz and Solar Ray, strengthening its position in Latin America’s rapidly expanding renewable sector. 

With Solar Ray, Korkia is advancing 800 MW of late-phase projects, including the Terrazas project in northern Chile (280 MW solar PV supported by a 1.24 GWh BESS), two standalone BESS projects and one solar project with co-located storage.

The partnership with Ciudad Luz includes 650 MW of late-phase projects, among them two hybrid solar and BESS developments combining generation and four-hour storage solutions to enhance grid flexibility and dispatchability.

Continued momentum across Korkia’s international portfolio

In early 2026, Korkia has also announced additional milestones across its international portfolio, including one of Finland’s first renewable energy hybrid projects reaching ready-to-build status and two solar projects securing Power Plant Approval in Alberta, Canada. Additionally, Korkia has announced the sale of two fully permitted solar PV projects, as well as the sale of a 10.7 MW portfolio of solar PV assets in Northern Italy.
