Dune Plus Solar-Battery in Chile Hits Financial Close

• Generadora Metropolitana seals non-recourse funding for Dune Plus, a Chilean solar-plus-storage hybrid marrying PV and multi-hour batteries to beat curtailment, shift peaks, and stabilize the grid.

Generadora Metropolitana closed non-recourse financing for its Dune Plus solar-plus-storage project in Chile’s Antofagasta region, launching procurement and construction. The hybrid couples PV on single-axis trackers with a multi-hour lithium-ion battery and grid-forming inverters. An energy management system will optimize arbitrage and ancillary services while co-location cuts losses and capex.

The deal backs a template Chile needs as northern solar is curtailed at midday but prices rise at dusk and in central load centers. Batteries shift surplus to peaks, bolster grid stability, ease congestion, and displace gas peakers. Financial close secures long-lead gear, enables staged energization, and embeds environmental safeguards.
