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.

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: a��base case, where all generation resources are available, and a no clean power case, where no��new��wind, solar, or storage projects are added beyond those already under construction or required by law.��

Key Data Points:����

• Without new clean energy development, ACP estimates that ratepayers across nine PJM states would pay an��additional��$360 billion��over the next ten years, driven primarily by higher wholesale electricity prices.����
• The average residential household would see��$3,000 to $8,500��in��additional��electricity costs over the��next��decade.������
• 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.��

It can provide best practices for companies as they develop worker safety plans and for workers as they get up to speed with industry safety best practices. It is intended to serve as a straightforward resource for clean energy workers and companies to familiarize themselves with key worker health and safety topics and share additional resources. Company policies would provide additional detail on these specific topics.

Key Considerations:

Why Farmland Is Sometimes Used for Solar

• Farmers may lease land for solar to create long‑term, stable supplemental income that strengthens farm financial resilience.
• Farmland’s flat, cleared terrain reduces grading and site‑prep costs, making it operationally efficient for solar siting.
  Projects sited on or near agricultural land can help minimize conflicts with sensitive resources (e.g., wildlife habitat, cultural sites).
• Brownfields, rooftops, and parking lots are also viable but come with higher costs, size limitations, additional permits, or liability risks, making them insufficient alone to meet national solar demand.

Solar as Part of a Long Tradition of Energy Production on Farms

• U.S. farmers already dedicate 40 million acres to corn for ethanol each year.
• Combined land use of corn‑for‑ethanol plus solar still totals under 6% of contiguous U.S. farmland.
• Solar provides 30–100× more energy per acre than corn grown for ethanol.

How Much Farmland Solar Actually Uses

• In 36 states, utility‑scale solar occupies less than 0.1% of prime farmland.
• In 12 states, solar occupies less than 0.01% of prime farmland.
• Nationally, the state average is just 0.07% of prime farmland used by solar.
• Only two states exceed 0.25% of prime farmland used for solar: California – 0.33% and Rhode Island – 0.31%
• Across 95% of counties with solar, it occupies less than 0.25% of total farmland.

Future Land Needs for Solar

• Even in the most land‑intensive 2050 scenarios modeled by DOE, about 10.3 million acres would be needed for new solar development.
• If all of this were placed on farmland (a scenario the fact sheet calls “highly unlikely”), it would affect less than 1.2% of existing U.S. farmland.

The Harris amendment injects permit uncertainty, and creates a pathway for fully permitted projects to be canceled even after the Act’s passage, during a time of skyrocketing energy demand and increasing energy prices.
