This tightens available supply, requires higher-cost generation to meet demand, and heightens risks to grid reliability. The heatwave clearly demonstrated which systems perform best under pressure—those with a diverse mix of power plants.

Key Takeaways:Ìý

• Overall, clean energy saved the grid more than $114 million during the 3-day heatwave. Wholesale electricity markets with significant wind, solar, and energy storage representation saw lower electricity prices than those without.
• Regions with high clean power penetration kept electricity prices low during the heatwave. When the heatwave hit, more expensive thermal units and imported electricity were required.
• If clean powerÌýhadn’tÌýbeen online,Ìýall ofÌýERCOT’s thermal capability would have been needed and may not have been enough to meet electricity demand.

Delivered quarterly, the US Energy Storage Monitor from the 91´«Ã½ Association (ACP) and Wood Mackenzie Power & Renewables provides the clean power industry with exclusive insights through comprehensive research on energy storage markets, deployments, policies, regulations and financing in the United States.

The U.S. energy storage market installed a record 3.3 gigawatts (GW)/8.4 gigawatt-hours (GWh) of battery energy storage systems in Q1 2026, surpassing the previous Q1 record by 54% with utility, commercial, and residential installations all hitting new highs, according to the latest U.S. Energy Storage Monitor report.

Utility-scale activity dominated, with more than 2.3 GW/6.8 GWh installed in Q1 2026. Q1 growth was largely driven by 2025 project delays as developers focused on meeting tax incentive eligibility deadlines for pipeline projects in the second half of 2025. Texas, California and Arizona continued to top the charts, but new markets with vertically integrated utilities also gained traction, particularly in Michigan and Georgia.

Battery energy storage system installations are projected to reach 200 GW/655 GWh of cumulative installed energy storage capacity by 2031, driven mainly by the utility sector, which will make up 85% of installations between 2026 and 2031.

Report Highlights:

• The U.S. installed 3.3 GW/8.4 GWh of battery energy storage systems across all sectors in Q1 2026, surpassing the previous Q1 record by 54%
• 2.3 GW/6.8 GWh of utility-scale capacity was installed in Q1
• Residential segment installed a record 1.3 GWh in Q1 2026
• The U.S. energy storage market is poised to grow by 275% in cumulative installed capacity over the next six years

The report also includesÌýkey 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 Q1 2026 Clean Power Market ReportÌýshowcasesÌýsteady development in the solar and storage sectors, while the pipeline for wind projects has slowed, due to ongoing federalÌýpushbackÌýand delays.ÌýÌý

The pipeline for clean power projects rose by 6% compared to Q1 2025, driven primarily by a 13% growth in the solar pipeline and 8% growth in the battery storage pipeline. In contrast, the pipeline for land-based wind has stagnated, and offshore wind has plummeted by 35%. Early-and-mid-stage land-based wind projects have struggled to secure approvals from federal regulators, and offshore wind continues to weatherÌýpermittingÌýroadblocks and uncertainty.Ìý

Report HighlightsÌý

• Capacity Continues to Climb:ÌýCumulative clean power capacity hit 370 GW in Q1 2026, enough to powerÌýnearly 80Ìýmillion homes.ÌýÌýÌý
• Pipeline in Flux:ÌýThe pipeline for clean power projects rose by 6% compared to Q1 2025, driven primarily by a 13% growth in the solar pipeline and 8% growth in the battery storage pipeline.ÌýDue to ongoing federal delays, the pipeline for land-based wind has stagnated, and offshore wind has plummeted by 35%.
• Solar Shines:ÌýMore than 3.6 GW of utility-scale solar capacity began operations in the first quarter, pushing cumulative operating capacity to 161.1 GW, enough to power 590,000 homes.
• A Slow Quarter for Capacity Installations:ÌýYear-over-year, overall clean energy quarterly capacity installations were down by 17%, compared to the 7,695 MW of capacity energized in Q1 2025. Q1 installations also fell by 66% compared to Q4 2025, which canÌýgenerally beÌýexpected as first quarters are typically much slower than fourth quarters.
• Delays Add Up:ÌýOver 6.4 GW of clean power capacity initially expected to become operational during Q1 were delayed, adding to the 53 GW backlog of delayed projects. Project developers often attribute project delays to lengthy permitting schemes, backlogged interconnection queues, and fluctuating prices for key project equipment.Ìý
• Texas Continues to Dominate:ÌýWith over 96.4 GW of clean power projects in operations, Texas is on the verge of becoming the first state to cross the 100 GW threshold. Texas is home to 26% of online capacity in the U.S. and has more operational capacity than the next four states combined.Ìý

The post America Builds Power: The State of Clean Energy Manufacturing 2026 appeared first on ACP.

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.Ìý

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:Ìý 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:ÌýExperts 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.ÌýÌý

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