Mexico Greenlights 1,488 MW of Battery Storage for Private Sector, Eyes New Round

Mexico has greenlit private developers to build 1,488 MW of battery energy storage (BESS) and is preparing a new allocation round for January, according to Energía Estratégica. It is one of the clearest signals yet that storage has moved from a marginal complement to a central component of system operations.

The decision comes as regulators seek to firm up Mexico's growing solar and wind generation, whose variability demands dispatchable backup during peak hours. Industry voices have described 2026 as the year battery storage takes off in Mexico, with new regulatory provisions defining how batteries integrate into the National Electric System, as reported by Mining México.

For developers, a confirmed allocation is the condition that unlocks project financing. The combination of solar, wind, and batteries is emerging as the new technical standard for reducing curtailment and capturing the value of clean capacity already installed. The January round will test how fast this segment can scale.

The next challenge is execution: connecting these projects to a transmission grid that also requires investment. The Watt will track the terms of the upcoming round and the first projects entering construction.
