Electric Storage Systems (ESS) are gaining ground in the Mexican electricity market 🚀🔋. As of June 2025, there are 206 MWh and 95 MW of usable capacity 📈, mainly distributed across the states of Baja California Sur (117 MWh), Quintana Roo (25 MWh), and Sonora (24 MWh).
What are the largest projects currently underway in Mexico? The main ones are:
La Toba (80 MWh) ☀️
Plan Sonora (24 MWh) 💡
The Mexican market is at a turning point where the combination of regulation, grid conditions, and costs makes ESS an attractive market in Mexico 🌍.
📜 Regulation
RES/113/2024 mandates that new intermittent renewable energy plant capacity must include at least 30% additional electrical storage capacity.
♻️ Supply Chains
Lazard's 2025 LCOE+ shows a reduction in the average Levelized Cost of Energy Storage (LCOS) of $233/MWh*, representing a 21% year-over-year decrease. This is due to a rebound in BESS manufacturing capacity and technological advancements in LFP batteries.
⚡The Future
The significant investment in BESS is progressively expanding towards peak shaving, more so in the National Interconnected System (SIN) than in isolated regions. With progress in regulation and price reductions, the future looks bright for the Mexican market.
