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.

• 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.

These quarterly programs keep members informed and engaged with ACP’s advocacy and work on behalf of our members and the clean power industry.

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.��

Early identification of potential issues (technical, environmental, contractual, or operational) is critical to minimizing risk and ensuring smooth project delivery.

A successful wind repower begins with a shared understanding of the project’s scope, constraints, and potential hazards. This includes legacy infrastructure, environmental considerations, and regulatory requirements. Proactive engagement during the planning phase allows teams to surface issues early, before contracting, and resolve ambiguities that could impact execution.

This document captures key lessons learned from repowering wind projects to help industry stakeholders anticipate risks, improve planning, and enhance safety outcomes. By identifying common hazards, regulatory complexities, and coordination gaps early in the process, teams can reduce incidents, streamline execution, and ensure compliance.

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.

In its analysis, ACP evaluated the impact of removing the five offshore wind projects from the system. The results were then translated into expected retail electricity rates across��15 states and Washington, D.C.��

Offshore wind plays a critical role shifting the “marginal unit” — the last and most expensive generator needed to meet demand — away from high-cost peaking plants toward more efficient and predictable��generation.��

Key findings��from the analysis��show that without these projects:����

• Wholesale electricity prices��would��rise significantly during evening peaks��and��winter hours –��including intense winter storms like Fern��

• Power systems would��rely more heavily on��non-renewable sources and leave customers more exposed to price��volatility��

• Grids would��lose access to low-cost, winter-peaking clean energy that helps stabilize prices during periods of high demand��

Key takeaways:

• Hundreds of thousands of people around the world live near and work in proximity to operating wind turbines with no ill health effects. More than 100 peer-reviewed scientific studies soundly discredit the claim that wind farms cause negative health impacts.
• The strongest epidemiological study suggests that there is not an association between noise from wind turbines and measures of psychological distress or mental health, nor is there evidence to link the noise to sleep disturbance or other physical health impacts.
• There is no scientific evidence to suggest that shadow flicker negatively affects human health. Several studies also conclude that shadow flicker from wind turbines does not pose a seizure risk.
• EMF levels measured at wind projects were four orders of magnitude lower than the levels known to cause harm to human health.

At the same time, wind energy delivers significant health benefits by reducing air pollution and lowering emissions tied to respiratory disease and premature mortality.
