Batteries just broke another record in the US

Summary

US battery storage capacity reached a record 20.2 gigawatt-hours in the second quarter of 2026, driven primarily by large-scale utility projects. While utility-scale growth remains robust, residential installations are experiencing a decline following the expiration of specific tax credits in 2025.

Key Takeaways

1. Battery installations hit a new record in the US in the second quarter of 2026.
2. In the behind-the-meter category, data centers led the way, making up about three-quarters of new batteries in the commercial sector.
3. Home installations are projected to drop by 16% in 2026 compared with last year, according to the report.

Credibility & Bias Reasoning

Credibility assessment: The reporting relies on named industry experts and joint findings from reputable market intelligence organizations. Factual claims include specific capacity figures, percentages, and market timelines. Minor projections regarding domestic supply chains remain speculative but are grounded in stated policy and manufacturing dynamics.

Bias assessment: Industry-Focused Reporting. The article maintains a neutral, informative tone focused on market growth and policy impacts. It presents both the record-breaking utility-scale growth and the decline in residential installations without editorializing. The perspective is strictly analytical, reflecting industry data rather than political advocacy.

Note: Findings are based on trade group reports and analyst assessments, with long-range manufacturing timelines remaining subject to trade and policy shifts.
