American Clean Power Report Shows 6.4 GW Of New Clean Power Added In Q1 2026 As Solar And Storage Continue To Lead Growth

The American Clean Power Association (ACP) has released its Q1 2026 Clean Power Quarterly Market Report, providing an overview of the current state of the United States clean energy sector and highlighting both continued progress and emerging challenges across solar, wind, and energy storage markets. The report shows that while solar and battery storage continue to expand steadily, the wind sector is experiencing slower growth due to regulatory delays and policy uncertainty.

During the first quarter of 2026, developers brought 6.4 gigawatts of new utility-scale solar, wind, and energy storage capacity online across the United States. This expansion has pushed the country’s total installed clean power capacity to more than 370 gigawatts, which is enough electricity to supply nearly 80 million homes.

The figures reflect the growing role of renewable energy in meeting rising electricity demand, driven by factors such as population growth, electrification, and increased industrial and digital energy use.The report also highlights a shift in the development pipeline for future projects. Overall, the clean power pipeline increased by 6 percent compared to Q1 2025, with solar energy and battery storage leading the expansion.

The solar pipeline grew by 13 percent, while the battery storage pipeline increased by 8 percent, indicating strong investor interest and continued project development in these segments. In contrast, the wind sector has faced growing challenges. The pipeline for land-based wind projects has largely stagnated, while offshore wind development has declined significantly, falling by 35 percent.According to the report, these challenges are largely driven by regulatory and permitting constraints.

Many early- and mid-stage wind projects are experiencing delays in securing federal approvals, while offshore wind developments continue to face uncertainty related to permitting processes and policy direction. These issues have contributed to slower project advancement and have added pressure to the overall clean energy development timeline.Commenting on the findings, ACP Chief Policy Officer JC Sandberg emphasized the importance of accelerating clean energy deployment to meet rising electricity demand and control energy costs.

He noted that clean energy projects remain among the fastest sources of new generation capacity and play a key role in supporting affordability and energy reliability. At the same time, he pointed to regulatory delays as a significant barrier preventing wind projects from moving forward, despite their potential to supply large amounts of low-cost electricity.The report’s Q1 2026 data also provides a breakdown of technology-specific performance.

Utility-scale solar performed strongly during the quarter, with more than 3.6 gigawatts of new solar capacity coming online. This brought total installed solar capacity in the United States to 161.1 gigawatts, which is sufficient to power approximately 590,000 homes. Solar continues to be one of the fastest-growing sources of new electricity generation in the country due to its relatively fast deployment timelines and declining costs.

However, the overall pace of clean energy installations showed some short-term decline. Year-over-year, total quarterly installations fell by 17 percent compared to Q1 2025. There was also a sharper decline when compared to Q4 2025, with installations down by 66 percent. The report notes that such quarterly fluctuations are not unusual, as first quarters typically see slower activity following strong year-end project completions in the previous quarter.

At the same time, project delays remain a significant concern for the industry. More than 6.4 gigawatts of clean energy capacity that was originally expected to come online in Q1 2026 was delayed. This has contributed to a broader backlog of approximately 53 gigawatts of postponed projects across the country. Developers have attributed these delays to several factors, including lengthy permitting procedures, congestion in interconnection queues, and volatility in equipment pricing.

These constraints continue to slow the pace at which new clean energy projects can be completed and connected to the grid.Despite these challenges, regional trends show strong concentration of clean energy development in certain states, particularly Texas. The state continues to lead the nation in installed clean power capacity, with more than 96.4 gigawatts of operational projects.

Texas is now approaching the 100-gigawatt milestone and accounts for roughly 26 percent of all clean power capacity in the United States. Its total installed capacity exceeds that of the next four leading states combined, highlighting its dominant role in the country’s renewable energy landscape.Overall, the Q1 2026 report presents a mixed picture of the US clean energy sector.

While solar and storage continue to expand rapidly and support growing electricity demand, structural challenges in permitting and regulatory processes are slowing wind development and contributing to project delays. As electricity consumption continues to rise nationwide, the ability to streamline approvals and accelerate deployment will play a critical role in determining how effectively the clean energy sector can scale to meet future demand.
