The project’s defining technical feature involves deploying up to 106 battery containers comprising a 90 MW / 450 MWh battery energy storage system. This BESS configuration addresses solar intermittency by enabling energy dispatch during peak demand periods and nighttime hours when generation ceases. The storage capacity positions Loma Verde among the largest integrated solar-plus-storage projects in the central Chilean zone, responding to grid flexibility requirements as variable renewable penetration increases across the Sistema Eléctrico Nacional.
Generated power will connect to the SEN through a 1.028-kilometer 66 kV transmission line terminating at the Litoral Central substation. The project includes construction of a 33/66 kV step-up substation with 110 MVA electrical capacity. Construction duration is projected at 14 months with operational start planned for 2027, contingent on environmental authorization from the SEA. The admission phase currently underway will determine whether additional studies or mitigation measures are necessary before advancing through the review process.
The Valparaíso Region project aligns with Chile’s accelerating deployment of utility-scale storage paired with renewable generation, a strategy gaining prominence as the country pursues decarbonization commitments. The integration of storage systems at this scale reflects broader sectoral trends across Latin America, where Chile leads in renewable capacity additions and storage pilot implementations. Operational details including employment generation and specific closure plans have not been disclosed in public environmental filings submitted to date.
