Clean Energy Pipeline Grows to $328 Billion, with 184 GW Primed for Deployment

The American Clean Power Association (ACP) released its Q1 2025 Clean Power Quarterly Market Report, showing continued strong private sector investment in domestic energy production. U.S. developers installed 7.4 gigawatts (GW) of utility-scale solar, wind, and storage capacity in the first quarter, marking the second-strongest start to a year on record and demonstrating strong market-driven demand for reliable, affordable domestic energy resources. 

The industry's growth is particularly strong in Republican-leaning states, where domestic manufacturing and energy production has created nearly 650,000 direct and indirect jobs and generates $3.4 billion in annual tax revenue and payments to landowners in rural communities. 

“Clean power is shovel-ready at scale. With unprecedented demand growth for electricity, we must send consistent investment signals across the energy sector,” said ACP CEO Jason Grumet. “We have the technology, investment capital, and workforce required to build the $300+ billion of clean energy projects in our development pipeline. The greatest threat to a reliable energy system is an unreliable political system.”   

Key Highlights 

• Total Installed Capacity: U.S. clean power capacity reached 320+ GW in Q1 2025, enough to power nearly 80 million American homes. 

• Strong Q1 Installations: 7.4 GW of new capacity came online, making it the second-strongest Q1 on record. The 115 project phases that came online in Q1 total $10 billion of private investment into the U.S. energy infrastructure.  

• Record-Breaking Storage Growth: Battery storage capacity surpassed 30 GW nationwide, representing a 65% increase year-over-year, with Q1 2025 setting a new first-quarter record at 1,602 MW. 

• Robust Project Pipeline: The development pipeline grew 12% year-over-year to reach 184,418 MW, with storage and wind pipelines growing 57% and 24% respectively. This represents $328 billion in project investment if everything in the pipeline is built. (Projects under construction or in advance stages of development (pipeline) are typically fully permitted projects. The growth of the pipeline does not signal any advances in the volume of projects receiving permits.)   

• Technology Mix: Q1 additions included 4,459 MW of utility-scale solar, 1,602 MW of storage, and 1,327 MW of land-based wind. 

• Leading States:  

  • Eight of the top ten states for Q1 clean power additions voted Republican in the 2024 presidential election. 

  • Texas leads the nation in clean power, with a portfolio reaching 80+ GW—a 20% increase from Q1 2024—and ranks first in utility-scale solar (28 GW) and land-based wind (43 GW) capacity. 

  • Indiana quadrupled its energy storage capacity in just one quarter, while adding 435 MW of new solar capacity. 

Powering America's Economic Growth 

With utility-scale clean power now exceeding 320 GW nationwide—enough to power nearly 80 million American homes—the data shows how rapidly private companies are responding to increasing power demands from manufacturing expansion, data centers, and AI development. 

Texas, the nation's energy leader, saw its clean power portfolio grow more than 20% since Q1 2024 to surpass 80 GW. The massive investment into clean power in the Lone Star State generates $1.3 billion annually in local tax revenue and land-lease payments and helps fuel the 125,000 direct, indirect, and induced jobs created by the industry for Texans. 

Strengthening Grid Reliability 

Battery storage achieved its strongest Q1 on record with 1.6 GW installed, pushing total U.S. storage capacity above 30 GW—a 65% increase from Q1 2024. This rapid deployment of energy storage strengthens grid reliability, providing critical backup power for American businesses and homes.  

Growing Pipeline Signals Confidence 

The clean power development pipeline grew 12% year-over-year to reach 184 GW, signaling continued job creation and private investment across America. The year-over-year increase was driven primarily by storage and wind: the storage pipeline grew 57% year-over-year to near 50 GW, and the land-based wind pipeline increased by 24% to 28 GW. These market-driven investments reflect growing demand for reliable, affordable domestic energy from utilities and major American companies.
