ACCIONA Energía doubles its commitment to energy storage in Chile with a new 1GWh battery

.

Spanish Investment in Chile

The Spanish company will build a new 196MW/980MWh BESS system at its El Romero photovoltaic plant in Atacama. This project, which will be operational by the end of 2027, strengthens the stability of the Chilean electricity grid and the integration of renewable energy in the country.

The renewable energy company ACCIONA Energía has announced a new strategic investment in Chile with the construction of a battery energy storage system (BESS) of 1GWhThe project, located in the desert of AtacamaThis will double the company's planned storage capacity in the country, consolidating its position in the Latin American energy market and reinforcing the stability of the local electricity grid.

This new installation will be integrated into the photovoltaic plant The rosemary (246MWp), one of the company's main plants in the region. With a capacity of 196MW/980MWhThe system will be able to supply 196 MW of clean energy continuously for five hours, a key factor in managing the intermittency of renewable energy sources. This infrastructure is scheduled to be commissioned by the end of 2027.

Doubling storage capacity for the Chilean network

This announcement comes in addition to the 1GWh storage project that ACCIONA Energía It already has construction underway at its solar complex. Malgarida (238MWp). With the combination of both initiatives, the company positions itself as a key player in the development of large-scale storage solutions, essential for the energy transition of ChileThe objective of these projects is twofold: on the one hand, optimize the management of renewable energy generated and, on the other hand, improve supply stability and security of the national electricity system.

The commitment to BESS technology allows the energy produced during peak solar radiation hours to be stored and injected into the grid when demand is higher or photovoltaic production decreases, thus guaranteeing a constant and reliable flow of clean electricity.

A consolidated portfolio in the Chilean energy market

With these two major storage projects, ACCIONA Energía accelerates its expansion in Chile, where it already operates an asset portfolio that totals 922MW of installed capacityIts diversified portfolio includes three wind farms —Punta Palmeras (45MW), San Gabriel (183MW) and Tolpán Sur (84MW)— and four photovoltaic plants: El Romero (246MWp), Malgarida (238MWp), Usya (64MWp) and Almeyda (62MWp). This strong presence underlines the importance of the Chilean market in the company's global growth strategy.

Key points and frequently asked questions about energy storage in Chile

How does this project affect Spanish companies with interests in Chile?

For Spanish companies that operate or export to ChileGreater stability in the electrical grid translates into a operational risk reduction and greater security of energy supply. Furthermore, it strengthens the image of Chile as a mature market for investment in clean technologies, opening up opportunities for the Spanish value chain in the renewables and engineering sector.

What impact does battery storage have on the renewable energy sector?

BESS storage is a critical technology that solves the main challenge of renewable energy: the intermittenceIt allows you to store surplus production from off-peak hours for use during peak consumption, which maximizes the profitability of solar and wind power plants and facilitates a greater penetration of clean energy into the energy mix without compromising the stability of the system.

Why is Chile a strategic market for this type of energy investment?

Chile It combines exceptional natural conditions, such as high solar radiation in the desert of Atacamawith a stable regulatory framework and a strong government commitment to decarbonization. This combination makes it a magnet for foreign investment in clean energy projects and cutting-edge technologies such as large-scale storage.
