REPORT: Q3 Market Report Shows Strong Quarter of Deployment, but Signs Point to Long-Term Slowdown Risk

Dec 4 2025


 

WASHINGTON, D.C. DecemberÌý4, 2025 –ÌýThe Âé¶¹´«Ã½ Association (ACP) released itsÌýClean Power Quarterly Market ReportÌýtoday, showing U.S. clean energy developers deliveredÌýa strong third quarter, adding aÌýrecord 11.7 gigawatts (GW) of new utility-scale solar, wind, and energy storage capacity. That isÌýenoughÌýcapacityÌýtoÌýpowerÌýover 1.6 million homesÌý–ÌýrepresentingÌýa 14% jump overÌýthe same period a year ago. Battery storage aloneÌýsurpassedÌýitsÌýpreviousÌýQ3 record with 4.7ÌýGWÌýinstalled.ÌýThisÌýstrongÌýyear was expected given the strong momentum and policy tailwinds supporting the industry over theÌýlast severalÌýyears.ÌýDespite strong near-term numbers,Ìýthe report highlightsÌýhow lingering policy and regulatory uncertainty put the pace of future growth at risk.Ìý

“The third quarter’s record results mask an unstable policy environment that is threatening our ability to meet our future energy needs,â€� saidÌýACP CEO Jason Grumet. “The policy chaos at the federal level has seeped into every part of project timelines, stalling growth precisely when we need to meet demand and keep energy prices affordable for American families and businesses.â€�ÌýÌýÌý

Decline inÌýPowerÌýPurchaseÌýAgreements:ÌýSomethingÌýtoÌýWatchÌý

While Q3 posted record installations, the forward-looking indicators tell a more concerning story.ÌýPower purchase agreements (PPAs) fell 31% year-over-year, pushing the year-to-date totalÌýfor all offtake typesÌý38% belowÌýthe same pointÌýlastÌýyear.ÌýÌý

Despite robustÌýdemand for power,ÌýbuyersÌýlargely satÌýon the sidelinesÌýinÌýthe third quarter,Ìýwaiting for a clearer policy environment toÌýemergeÌýandÌýthe rules around tax credit eligibility for developing future projectsÌýto be set.ÌýTreasury’s long-awaited guidance on transferable tax credits and foreign-entity-of-concern rules only landed halfwayÌýthrough Q3,ÌýthisÌýcomplicatedÌýfinancing conversations and resultedÌýinÌývirtually noÌýnet pipeline growthÌý(<1 %), quarter-over-quarter.ÌýÌýÌý

“Demand from AI, data centers, and onshoring manufacturing is set to push U.S. electricity needs to all-time highs next year,â€� added Grumet. “With swift policy action, this demand can be met with domestic clean energy, supporting U.S. competitiveness in the race for these new technologies.â€�ÌýÌý

  • Total Clean Power Capacity Installed: Strongest Q3 on record.ÌýTotal clean power capacity installed in Q3Ìý2025ÌýatÌý11,695 MWÌýrepresentsÌýa 14% increase YOY. Of that capacity, land-based wind increased 131% over Q3 2024.Ìý
  • Pipeline Hits All-time HighÌýbutÌýGrowth Stalls: The clean power pipeline reached a new high of 186,185 MWÌýby the end of September, growing 9% YOY. However, the pipeline expanded a mere 1% from the first quarter ofÌý2025.ÌýÌý
  • 2025 On PaceÌýforÌýa Strong Year: YearÌýtoÌýdate,Ìý30.9 GW ofÌýcleanÌýenergyÌýpowerÌýgenerationÌýhas been connected to the grid, up 1ÌýGW from the current top year (2024) for clean energy installation.Ìý
  • Offtake AgreementsÌýinÌýDecline: Clean energy offtake announcements during the first three quarters of 2025 wereÌýdown 38%,Ìýcompared to theÌýsame period in 2024.Ìý
  • StatesÌýSet toÌýDouble Clean Energy Portfolios:ÌýEleven 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,ÌýTennesseeÌýand Virginia.ÌýÌý
  • Offshore Wind Faces Challenges: No capacity changes during Q3, but moving into the fourth quarter, the offshore wind pipeline will decline, afterÌýInvenergyÌýsubmittedÌýa petition to cancelÌýits OREC agreementÌýwith the New Jersey Board of Public UtilitiesÌýfor Leading Light Wind (2,400 MW).ÌýÌý
