Briefings

A 2026 report by Ember estimates that only 3% of global data center capacity can shift electricity demand by 2030, leaving 87% for fixed cloud and AI services. Analysis of nine global markets shows peak demand reductions of 0.1% to 0.6% in the U.S., with Texas leading at 0.4%. The report identifies onsite generation and batteries as key solutions, noting non-firm interconnection rules could drive a 285 GWh U.S. battery market by 2035. Battery needs increase with more flexible data centers, potentially requiring 1.3 to 7 hours of storage depending on grid curtailment rules.

Key points

• Ember's 2026 research indicates only 3% of global data center capacity can shift electricity demand by 2030, with 87% remaining fixed for cloud and AI services.
• Load shifting reduces peak demand by 0.1% to 0.6% in nine global markets, with Texas contributing up to 0.4% reduction in the U.S.

Context

The report analyzes nine major global data center markets, finding that load shifting reduces peak demand by 0.1% to 0.6% by 2030. The Federal Energy Regulatory Commission directed grid operators to justify or revise rules for connecting large loads, following Department of Energy orders to accelerate connections. This context explains why flexible data centers are seen as a way to secure faster grid hookups and shield customers from new infrastructure costs.

Limitations

Analysis covers nine major global data center markets including Texas, California, and New York. Findings on peak demand reduction are based on modeled scenarios; actual outcomes may vary. Battery market projections assume half of forecasted data center load leverages flexibility and use batteries to cover curtailments. Storage duration needs range from 1.3 to 7 hours depending on grid curtailment rules and specific market implementation.
