The primary avenue by which industry works with the Department of Defense (DoD) to address national security concerns about potential wind projects, both on- and offshore, is through the DoD Military Aviation and Installation Assurance Siting Clearinghouse (“Clearinghouse”).

This fact sheet provides background on ensuring offshore wind projects are compatible with military readiness.

Delivered quarterly, the Wind Energy Monitor from the American Clean Power Association (ACP) and Wood Mackenzie Power & Renewables provides the clean power industry with exclusive insights through comprehensive research. This Q4 2025 release includes Q3 2025 in review, plus a 5-year look-ahead outlining expected capacity buildout, costs, supply chain, policy, and investment. 

 Report Highlights 

• Amid a challenging market environment, the report shows that the US is on track to add 46 GW of new wind capacity from 2025 to 2029, with total projected volumes unchanged quarter-on-quarter from previous forecasts. 
• Timing has shifted, as 2026 and 2027 will deliver significant gains, at 10.7 GW and 12.7 GW, respectively, as more assets advance through the development pipeline.
• The market has shown progress with 3.8 GW queued for Q4 2025—representing 52% of the year’s total expected capacity. This back-loaded installation pattern is consistent with typical project-commissioning timelines. 

US turbine order intake has rebounded to pre-One Big Beautiful Bill Act (OBBBA) levels quarter-over-quarter, supported by 2+ GW of firm commitments in Q3, the biggest intake in the region in the last 9 months and a 79% quarter-over-quarter increase. However, true visibility remains limited as OEMs increasingly withhold project details and much qualifying “start-of-construction” activity occurs through off-site component manufacturing. 

The report also includes key quarterly trends and analysis on impactful market regulation, policy, system prices, and supply chain across all segments. The report provides industry professionals with actionable and intelligent insights to better inform business decisions.

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.

ACP partnered with leading developers, legal experts, and market innovators to explore the state of play and introduce a new standardized ITC transfer agreement form. 

The new Tax Credit Transfer Agreement (TCTA) form is designed to standardize the legal documentation for these transactions, aiming to lower barriers to entry, reduce transaction costs, and shorten deal timelines, especially for first-time buyers and smaller sellers.

Key details about the TCTA form and the transferability market:

• The market for buying and selling clean-energy tax credits is growing fast: Tax credit transfers have scaled dramatically — from under $10 billion in 2023 to an estimated $40 billion in 2025 across various technologies like solar, wind, manufacturing, storage, and nuclear.
• ACP and industry partners have introduced the new Tax Credit Transfer Agreement (TCTA) to make deals more accessible to a broader range of market participants:  Tax credit buyers and sellers will have a common starting place to transact transfer deals. ACP’s goal in creating the form with its industry partners is to make the form broadly available and widely used similar to the ubiquitous ISDA framework for derivative transactions.
• This is just the first step — more standardized tools are coming: Experts expect similar templates for other credits like 45Y production tax credits and 45X manufacturing incentives further expanding the pool of potential tax equity investors. As these tools roll out, buying and selling credits should become easier, helping clean energy scale more quickly.  

A consistent, tested, and accepted template provides the confidence and guidance these new participants need to transact.

 At the same time, leading indicators point to emerging headwinds. Power purchase agreements (PPAs) fell 31% year-over-year, pushing the year-to-date total for all offtake types 38% below the same point last year. Looking further ahead, the policy and regulatory environment has changed. Projects are facing heightened regulatory burdens and policy uncertainty, putting the future trajectory of clean power project deployments at risk. 

Key Highlights

• Total Clean Power Capacity Installed: Strongest Q3 on record. Total clean power capacity installed in Q3 2025 at 11,695 MW represents a 14% increase YOY. Of that capacity, land-based wind increased 131% over Q3 2024. 

• Pipeline Hits All-time High but Growth Stalls: The clean power pipeline reached a new high of 186,185 MW by the end of September, growing 9% YOY. However, the pipeline expanded a mere 1% from the first quarter of 2025.  

• 2025 On Pace for Biggest Year Ever: Year to date, 30.9 GW of clean energy power generation has been connected to the grid, up 1 GW from the current top year (2024) for clean energy installation, putting 2025 on track to be the strongest year on record.  

• Offtake Agreements in Decline: Clean energy offtake announcements during the first three quarters of 2025 were down 38%, compared to the same period in 2024. 

• States Set to Double Clean Energy Portfolios: Eleven states have enough capacity in their pipelines to more than double their operational portfolios: Alabama, Arizona, Delaware, Kentucky, Maryland, Massachusetts, Michigan, New Jersey, New York, Tennessee and Virginia.  

• Offshore Wind Faces Challenges: No capacity changes during Q3, but moving into the fourth quarter, the offshore wind pipeline will decline, after Invenergy submitted a petition to cancel its OREC agreement with the New Jersey Board of Public Utilities for Leading Light Wind (2,400 MW).

In a letter to Speaker Mike Johnson and Democratic Minority Leader Hakeem Jeffries, the organizations voiced strong support for the SPEED Act (H.R. 4776) — legislation that would streamline reviews, reduce delays, and provide greater certainty for energy infrastructure investment. The coalition emphasizes that clearer, durable permitting rules are essential for delivering reliable and affordable power to families and businesses. 

The Q2 U.S. wind market installed 593 megawatts (MW), down 60% compared to Q2 2024. But installations through the first nine months of 2025 are projected to outpace 2024 by 18%, reaching a total of 3.49 gigawatts (GW), according to the latest quarterly analysis from Wood Mackenzie and the American Clean Power Association (ACP).

Despite the slowdown in Q2, activity is projected to pick up, with 51% of forecasted capacity to come online in Q4, rounding out the annual 2025 total to 7.7 GW.

The post-OBBBA US onshore wind market outlook increased by 3.6% (2.4 GW) for onshore wind new builds quarter-on-quarter, as developers focus on bringing projects to commercial operation before the tax credit expiration deadline. The quarterly report projects a total of 5.9 GW of offshore wind capacity to come online by 2029, with 2026 and 2027 accounting for the bulk of activity.
