This presentation will provide a deep dive into findings from ACP’s Clean Power Annual Market Report | 2025, highlighting the factors that set 2025 apart from previous years and what they signal for the future of the industry.

California faces rising electricity prices, surging energy demand and ambitious clean energy goals. To stabilize costs and reliably power its economy, the state needs to be able to bring new clean power online quickly and efficiently.

Right now it’s difficult, costly and slow to add new power to the grid. Clean energy projects often wait years for investor-owned utilities to make equipment upgrades needed to accommodate the new power. The California Public Utilities Commission these delays affect nearly two-thirds of upgrades in two investor-owned utilities’ territories.

AB 2493 would require an independent auditor to assess the utilities’ progress in resolving the delays and would employ a mix of carrots and sticks to get utilities to prioritize the upgrades. It would prioritize upgrades where clean energy projects are waiting, speeding new power to the grid, saving money and making it easier for California to stay on top of rising demand.

Developers brought 18.6 gigawatts (GW) of new utility-scale solar, wind, and energy storage online in Q4 alone — pushing the 2025 annual total to more than 50 GW. That’s enough electricity to power more than 6.9 million homes.

These three technologies accounted for 90.5% of all new power capacity in 2025 and over 80% of capacity additions over the previous five years, according to ACP and the U.S. Energy Information Administration. These numbers were expected given the strong policy tailwinds of 2024, but future growth remains uncertain as federal policy chaos leads to investor hesitation.

Key Highlights

• Strongest Clean Power Year on Record: Total clean power capacity installed in 2025 reached 50,344 MW — a 3% increase over 2024 and the first-time annual deployment has surpassed 50 GW.
• Storage Surges: Energy storage installations were 41% higher than 2024 — the previous record year. The storage development pipeline continues to expand, growing 2% year-over-year.
• Medium-term Pipeline Outlook Increasingly Uncertain: The near-term pipeline rose to 187,514 MW. However, growth is slowing with only two GW added during the fourth quarter. A 27% year-over-year drop in PPA announcements is an early warning sign.
• Offshore Wind Under Pressure: No new offshore wind capacity came online in Q4, and the pipeline contracted following project cancellations, including Invenergy’s petition to terminate its OREC agreement for Leading Light Wind.
• Value Proposition for States: Nineteen states grew their clean power capacity by more than 20% in 2025, with Kentucky increasing its capacity by 188% to reach the Top 10 for 2025 solar installations. Increased adoption is set to continue: 35 states have more than 1 GW of clean power in the pipeline.

Key Highlights

• Strongest Clean Power Year on Record: Total clean power capacity installed in 2025 reached 50,344 MW — a 3% increase over 2024 and the first-time annual deployment has surpassed 50 GW.
• Storage Surges: Energy storage installations were 41% higher than 2024 — the previous record year. The storage development pipeline continues to expand, growing 2% year-over-year, signaling sustained long-term demand.
• Medium-term Pipeline Outlook Increasingly Uncertain: The near-term pipeline rose to 187,514 MW. However, growth is slowing with only two GW added during the fourth quarter. A 27% year-over-year drop in PPA announcements is an early warning sign for lower clean power deployments in 2028-2030.
• Offshore Wind Under Pressure: No new offshore wind capacity came online in Q4, and the pipeline contracted following project cancellations, including Invenergy’s petition to terminate its OREC agreement for Leading Light Wind. Continued federal and regulatory interference is creating additional headwinds for the sector.
• Value Proposition for States: Clean power is delivering low-cost power, jobs, and a boost to local economies across the U.S. — with projects operational in all 50 states. Nineteen states grew their clean power capacity by more than 20% in 2025, with Kentucky increasing its capacity by 188% to reach the Top 10 for 2025 solar installations. Increased adoption is set to continue: 35 states have more than 1 GW of clean power in the pipeline.

There is a growing mismatch between demand growth and new conventional generation that presents an immediate challenge to grid reliability and affordability across the PJM region. To evaluate system-wide impacts, ACP modeled PJM under two scenarios: aÌýbase case, where all generation resources are available, and a no clean power case, where noÌýnewÌýwind, solar, or storage projects are added beyond those already under construction or required by law.Ìý

Key Data Points:ÌýÌý

• Without new clean energy development, ACP estimates that ratepayers across nine PJM states would pay anÌýadditionalÌý$360 billionÌýover the next ten years, driven primarily by higher wholesale electricity prices.ÌýÌý
• The average residential household would seeÌý$3,000 to $8,500ÌýinÌýadditionalÌýelectricity costs over theÌýnextÌýdecade.ÌýÌýÌý
• In the “no new clean power” case, PJM becomes increasingly reliant on aging, higher-cost fossil fuel generation and imported electricity. Net power imports rise nearly 300% by 2035, increasing exposure to fuel price volatility and operating hours with extremely high electricity prices.Ìý
