The 2026 Q2 Clean Power Market Report showcases steady development in the solar and storage sectors, while the pipeline for wind projects has slowed due to ongoing federal pushbacks and delays.

The quarter marked the strongest second quarter and first half of a year on record for clean energy deployments, demonstrating that companies and utilities continue to recognize the value of clean energy as a fast, affordable power source, even in an unstable policy environment.

Report Highlights:

• New Mexico led the nation in new clean power capacity additions, adding 3.6 GW to the grid from Pattern Energy’s SunZia project and ending Texas’ two-and-a-half-year streak as the top state.
• Battery storage surpassed 50 GW of installed capacity nationwide and now stands at nearly 53 GW.
• The clean power pipeline reached a record 205 GW, up 20 GW (11%) year-over-year.
• Clean power procurement totaled 14.5 GW, up 23% year over year, with power purchase agreement announcements reaching an all-time first-half record.
• Despite the sector’s strong performance, federal permitting and review delays continue to threaten future development, particularly for land-based wind projects, contributing to a 4% decline in the land-based wind pipeline.

The difference is clear:

• Faster to build: Clean power projects spent an average of less than a year in development last year, while gas turbines spent two to three years in advanced development and construction.
• Faster to connect: Due to its robust project pipeline, clean power projects take six months to two years to connect to the grid, whereas unplanned gas generators can take an average of five to seven years.

Clean energy is keeping our country’s grid stronger and less reliant on slower, costlier sources of energy. To quickly and affordably meet future energy needs, we need to leverage the speed and low cost of clean energy projects.

Across the areas most affected by the heatwave, wind and solar generation increased during the highest-demand hours compared to the days before and after the event, providing electricity when it was needed most. Markets with higher levels of clean energy experienced substantially lower wholesale electricity prices, while regions with relatively little clean generation experienced the highest prices despite having tens of gigawatts of clean energy waiting to connect to the grid.

To quantify the value of additional clean energy, ACP modeled a scenario in which advanced utility-scale solar, wind, offshore wind, and battery storage projects — totaling 74 GW — currently awaiting interconnection in MISO, PJM, NYISO, and ISO New England had already been operating.

The results were clear:

• More than $170 million in wholesale electricity cost savings during the July heatwave, thanks to clean power.
• Lower reliance on expensive gas, coal, and oil peaking generation.
• Improved system reliability, including avoiding modeled reliability shortfalls during the highest-demand hours.
• Lower wholesale electricity prices across every modeled region.

Extreme weather events are becoming more frequent, and electricity demand continues to rise. This analysis demonstrates that expanding clean power is not simply an emissions strategy — it is a reliability and affordability strategy. Bringing shovel-ready clean energy projects online faster would reduce consumer costs, strengthen grid reliability, and lessen dependence on the most expensive generating resources when Americans need electricity the most.
