Q1 2026 U.S. On-Site Battery Storage Opportunities

Key Takeaways

• Utility rate increases show no signs of easing. Utilities are investing heavily to meet projected AI load growth, with transmission and distribution capital expenditure (CapEx) plans potentially adding $1.2 trillion from 2025–2029. PJM’s capacity auction cleared again at the $333/MW-day ceiling, and wholesale prices exceeded $4,000/MWh during Winter Storm Fern.
• Illinois emerges as a top-tier battery market. The Clean and Reliable Grid Affordability (CRGA) bill sets a 3,000 MW storage target by 2030 with rebates of $250–300/kWh that can cover roughly half of project costs, on top of 30–40% federal investment tax credits. Ameren grid charges have risen nearly 20% annually since 2020, and ComEd’s proposed $15 billion in infrastructure spending will likely push commercial and industrial (C&I) charges higher.
• New state programs are launching across the Northeast and Midwest. New Jersey is expected to issue solicitations for 850–1,550 MW of battery capacity in 2026. Maryland is accelerating procurement of 800 MW of grid-scale batteries and 150 MW of distributed systems on C&I sites. Massachusetts’ new siting law mandates 12-month permit decisions, removing a key bottleneck.
• Developer competition is intensifying for strategic sites. Strong battery revenues in the NYC area are driving above-market lease offers for sites under 0.5 acres. National Grid’s smart grid reform is creating similar competition for upstate New York properties near strategic substations. In New Jersey and Maryland, developers are paying premium lease rates to secure site control ahead of upcoming RFPs.
