Zelestra has energized its Aurora battery energy storage system in Chile, combining 1 GWh of storage capacity with 220 MWdc of solar generation in the Tarapacá region. The project completed its first nighttime discharge in May 2026, ten months after securing $282 million in financing, marking one of the fastest construction timelines for gigawatt-hour scale […]
The Madrid-based engineering consultancy has established itself as a leading technical advisor for battery storage projects in strategic markets including Chile, Australia, and the United States. The firm’s accumulated experience across more than 150 GWh positions it to capitalize on accelerating BESS deployment as quality assurance becomes increasingly critical to project bankability. Enertis Applus+ has
Canadian independent power producer Innergex has brought online its second battery installation at the San Andrés solar facility in Chile’s Atacama region, doubling the site’s storage capacity to 77 MW/385 MWh. The newly operational San Andrés II system marks the completion of a phased expansion strategy that positions the company to capitalize on Chile’s volatile
Two major standalone battery energy storage projects have advanced through Chile’s environmental review process, representing combined investment of $556 million and signaling continued grid-scale storage deployment despite mounting regulatory uncertainty under the incoming Kast administration. The Águila Mora and Black BESS projects total 650 MW of capacity and would add critical flexibility to Chile’s renewable-heavy
Chile’s energy storage buildout has accelerated beyond initial projections, with 38 battery systems totaling 4,597 MW and 18,780 MWh now under construction alongside 2,119 MW in testing phases. The momentum positions the country to exceed its original 2030 storage target of 2,000 MW by early 2026 and approach its 6,000 MW goal for 2050 within
Brazil’s state energy planning agency EPE projects the country could deploy 7 GW of battery storage and 3 GW of demand response capacity by 2035, contingent on regulatory progress and stable legal frameworks. The projections form part of the National Interconnected System’s capacity planning amid mounting grid flexibility challenges, with short-term flexibility requirements expected to
A 66 kV transmission system paired with battery energy storage infrastructure has entered Chile’s environmental impact assessment process in the O’Higgins region, targeting a 30-year operational timeline with grid injection capabilities. The project’s location in Marchigüe commune positions new storage capacity in central Chile’s evolving energy infrastructure landscape, with construction scheduled across a multi-phase timeline.
Sonnedix has secured three long-term power purchase agreements with Copec EMOAC to underpin its Sonnedix Librillo battery storage project in Chile’s Antofagasta region, marking a structural shift toward contracted storage assets in the country’s electricity market. The 643.8 MWh facility positions battery capacity as infrastructure critical to grid operations as renewable integration accelerates. Sonnedix closed
Brazil’s anticipated energy storage auction faces mounting uncertainty as the Ministry of Mines and Energy and national grid regulator Aneel struggle to finalize critical framework rules. Industry executives warn that unless a ministerial directive is published within 15 days of mid-April 2026, the auction becomes non-viable this year, with political distractions including elections and the
