EIA Projects Record U.S. Solar Capacity in 2026 as Texas Drives Renewable Buildout
New federal data show 86 gigawatts of generating capacity expected nationwide, with solar comprising more than half and Texas anchoring the country’s largest planned expansion.
The U.S. Energy Information Administration’s March 2026 Short-Term Energy Outlook projects that domestic power developers will bring 86 gigawatts of new utility-scale generating capacity online this year — a figure that, if realized, would represent the highest single-year total in the nation’s history. Solar photovoltaic installations account for 51 percent of planned additions, followed by battery energy storage at 28 percent and wind at 14 percent. Within that national picture, Texas stands out as the dominant contributor: the state accounts for approximately 40 percent of planned utility-scale solar additions and 53 percent of planned battery storage capacity for 2026, reinforcing its position as the leading U.S. market for grid-scale renewables deployment.
The scale of anticipated additions reflects converging forces that have been building for several years. Equipment costs continue to fall — battery storage is now priced at roughly $117 per kilowatt-hour, less than a third of 2023 levels — making large solar-plus-storage configurations economically viable without relying primarily on federal subsidies. The EIA expects utility-scale solar generation to increase by 21 percent in both 2026 and 2027, driving the combined share of wind and solar in the U.S. generation mix from approximately 18 percent in 2025 to 21 percent by 2027. The renewable energy expansion is occurring against a backdrop of notable federal policy headwinds, including the rollback of clean energy tax credits and new restrictions on supply chains, yet industry analysts broadly agree that the underlying economics are sufficiently compelling to sustain near-term buildout momentum. The American Clean Power Association noted that 2025 set a record for energy storage additions, establishing a trajectory that 2026 activity appears poised to extend.
Within the Electric Reliability Council of Texas, the fastest-growing generation source is solar, which the EIA forecasts will expand by 92 percent between 2024 and 2026. The ERCOT grid entered 2026 with approximately 13.9 gigawatts of commercially operational battery energy storage — a figure that led the nation, surpassing California for the first time — and developers plan to add another 12.9 gigawatts of battery capacity through the balance of the year. This infrastructure expansion is being driven in part by rising electricity demand from data centers and heavy industry, with the EIA projecting ERCOT load growth of approximately 21 percent between 2024 and 2026. Beyond Texas, the 3,500-megawatt SunZia Wind project in New Mexico, currently one of the largest onshore wind facilities under construction in the Western Hemisphere, is targeting commercial operations in 2026, with transmission infrastructure that will connect southwestern renewable resources to broader regional load centers. The Tehuacana Creek 1 Solar and Battery Energy Storage System in Texas — an 837-megawatt solar facility with an additional 418 megawatts of storage — is expected to be the single largest solar project to reach commercial operation this year.
Developments of this scale and complexity typically create sustained demand for a range of engineering and operational disciplines. Large-scale solar and storage projects require electrical and civil engineers with interconnection and balance-of-plant experience, along with construction project managers capable of coordinating multi-phase, multi-hundred-megawatt builds. The integration of substantial battery storage capacity into grid operations — particularly within a deregulated market like ERCOT — may increase demand for power systems engineers, energy trading specialists, and grid operations professionals who understand the dispatch economics of paired solar-storage assets. As transmission infrastructure expands to accommodate new generation, project development roles requiring familiarity with permitting, environmental review, and Federal Energy Regulatory Commission interconnection procedures are likely to be in demand across developer, utility, and independent power producer organizations. The increasing reliance on software and digital tools for grid management may also draw on professionals at the intersection of energy operations and technology integration.
Industry participants and regulatory observers will be tracking several indicators over the coming months. The pace of interconnection queue processing by ERCOT and other regional transmission organizations will influence whether 2026 additions match planned figures, as interconnection timelines have historically been a limiting factor in solar buildout. The SunZia Wind project’s commercial operation schedule will be closely watched as a signal for large-scale western wind development viability. Battery storage performance during peak summer demand periods — particularly in Texas, where grid stress events have drawn national attention in recent years — will inform both regulatory policy and future investment decisions. Additionally, the trajectory of data center power purchase agreements is expected to continue influencing siting and capacity decisions for developers across the Southwest and Plains states.
