Global energy storage deployments are forecast to increase 45% year on year in 2026, according to energy-storage.news, citing BloombergNEF. The research house also projects that the market will maintain sustained, rapid growth over the coming decade and reach 3.1 TW of cumulative capacity by 2036.

Why It Matters

For battery buyers serving energy storage systems, a 45% annual deployment increase signals sustained demand for cells, battery packs and related materials. The forecast also points to a larger long-term addressable market, potentially affecting how suppliers allocate production capacity and how buyers should structure procurement arrangements.

Scale does not automatically translate into lower prices or faster delivery. Buyers should assess whether suppliers can support rising volumes while maintaining consistent specifications, quality controls and traceability. Rapid market expansion may also increase competition for qualified cell production lines and suitable pack components, making capacity reservations, lead-time commitments and supplier diversification more important.

Qualification will be a central procurement issue. As deployments expand, buyers need confidence that incoming cells and packs match approved electrical, mechanical and safety requirements. Contracts should therefore address lot consistency, documentation, warranty responsibilities and remedies for supply interruptions. The 3.1 TW cumulative capacity projection by 2036 further supports the case for long-term capacity planning rather than short-term, spot-based purchasing alone.

Implications for Buyers

Suppliers should be asked to provide:

• What production capacity is available for the buyer’s required cell or pack specification, and what lead times should be expected through the forecast growth period?
• How will quality assurance, batch traceability and product consistency be maintained as production volumes increase?
• What capacity-reservation, volume-commitment and supply-continuity terms can the supplier offer across the buyer’s planned procurement cycle?
