US Renewable Energy Capacity Set for Record 62% Jump in 2026 as Solar and Batteries Dominate Grid Expansion
Published · 6 min read
The United States is adding 86 gigawatts of new power capacity in 2026, nearly double the previous year’s total, according to data from the Energy Information Administration. Solar, wind, and battery storage will account for 79 percent of all new generating capacity, while fossil fuel plants continue to retire.
The scale of this growth marks a turning point in American electricity generation. By year’s end, renewable energy capacity will surpass natural gas for the first time in history.
Solar Power Surges 60% in a Single Year
Developers plan to install 43.4 gigawatts of utility-scale solar capacity this year, up 60 percent from 2025. If completed on schedule, 2026 will mark the third consecutive year of record solar installations nationwide.
Texas leads the buildout with 40 percent of planned solar projects, representing about 17.4 gigawatts. Arizona and California each account for roughly 6 percent of new solar capacity.
The Tehuacana Creek 1 Solar facility in Texas exemplifies the new scale of development, bringing 837 megawatts of solar panels online alongside 418 megawatts of battery storage.
Solar electricity generation is forecast to jump from 290 terawatt-hours in 2025 to over 420 terawatt-hours by year’s end, a 45 percent increase in just 12 months. Over the past decade, solar has grown nearly eight-fold, making it the fastest-growing electricity source in US history.
Battery Storage Rises 57% to Enable Round-the-Clock Clean Power
Battery installations are keeping pace with solar growth. Utilities plan to add 24 gigawatts of energy storage in 2026, beating last year’s record by 57 percent.
This surge in storage capacity solves a critical challenge: batteries capture excess solar generation during the day and release it during evening peak demand. About 48 percent of current utility-scale storage is paired directly with solar arrays.
Three states dominate battery deployment. Texas accounts for 53 percent of planned storage with 12.9 gigawatts, followed by California with 14 percent and Arizona with 13 percent.
Major projects include the Lunis Creek Battery Energy Storage System in Texas at 621 megawatts and the Clear Fork Creek Solar and Battery Storage facility, also in Texas, at 600 megawatts.
Over the past five years, more than 40 gigawatts of battery storage has been added to the American grid. Battery costs have fallen roughly 20 percent annually over the past decade, making storage economically viable at scale.
Wind Power Returns After Slowdown
Wind energy is staging a comeback with 11.8 gigawatts planned for 2026, more than double the 5.5 gigawatts added last year. New Mexico, Texas, Illinois, and Wyoming will host almost 60 percent of new wind capacity.
Two delayed offshore projects are finally launching. Vineyard Wind 1 in Massachusetts brings 800 megawatts online, while Revolution Wind in Rhode Island adds 715 megawatts.
The most significant development is the 3,650-megawatt SunZia Wind project in New Mexico, which will become the largest onshore wind farm in the country when it begins operations this year.
Wind already provides 10.3 percent of total US electricity. Combined with solar, the two sources generated 15.7 percent more electricity than coal in 2025 and 8.7 percent more than nuclear plants.
Renewables Provide All Net New Capacity as Fossil Fuels Shrink
When plant retirements are factored in, fossil fuel capacity will decline by 4,211 megawatts in 2026 even as some new gas plants open. Renewables and battery storage account for essentially all net new capacity additions.
During 2025, renewable energy capacity grew by 55,809 megawatts, while fossil fuels and nuclear combined grew by just 773 megawatts. No new nuclear capacity is forecast for 2026.
By the end of this year, total renewable capacity is projected to reach 525,356 megawatts, surpassing natural gas at 514,213 megawatts. Renewables will represent 40 percent of all installed generating capacity, up from roughly 5 percent just a decade ago.
Economics Drive the Transformation
The renewable surge is powered by simple economics. More than 90 percent of new renewable projects globally now cost less than comparable fossil fuel plants.
Utility-scale solar electricity costs between $29 and $92 per megawatt-hour, while onshore wind ranges from $27 to $53. Natural gas costs $110 to $228 per megawatt-hour, and coal runs $69 to $169.
This cost advantage explains why renewable deployment continues despite political headwinds. Developers are racing to complete projects before federal tax credits potentially expire, but the underlying economics favor renewables with or without subsidies.
Rising Electricity Demand Creates Urgency
The nation faces its strongest four-year growth in electricity demand since 2000, driven primarily by data centers and artificial intelligence infrastructure. The EIA forecasts demand will rise 1 percent in 2026 and 3 percent in 2027.
This surge creates both challenge and opportunity. The grid must expand faster than ever before, but only renewables are being deployed at the necessary scale. Coal capacity is shrinking, gas additions are slow, and no new nuclear plants are under construction.
The electrification of transportation, heating, and industry is shifting energy consumption toward the grid just as clean electricity becomes the dominant new supply source.
Obstacles Remain Despite Momentum
Nearly 700 gigawatts of solar, wind, and storage projects sit in interconnection queues, waiting for grid upgrades and regulatory approvals. Permitting delays and supply chain issues slow deployment in some regions.
New sourcing rules targeting components from China, Russia, Iran, and North Korea will force manufacturers to diversify supply chains and potentially raise costs. Labor shortages in construction and electrical trades could also constrain installation speed.
Proposed elimination of clean energy tax credits could increase solar costs by 36 to 55 percent and onshore wind by 32 to 63 percent, though this would primarily affect projects starting after 2026.
Coal Plants Continue Closing Despite Political Support
Coal’s share of US electricity will fall from 17 percent in 2025 to 15 percent by 2027, continuing a long-term decline. Coal capacity dropped 4,397 megawatts in 2025, with further retirements expected.
Three-quarters of American coal plants are more than 40 years old, and only 14 percent are less than 20 years old. The aging fleet faces mounting maintenance costs that make plants uneconomical to operate.
No new coal plants are under development anywhere in the country. The fundamental economics of electricity generation have rendered coal uncompetitive against both natural gas and renewables.
What Comes Next
The transformation of America’s electricity system is accelerating beyond what political forces can reverse. The momentum from falling technology costs, improving efficiency, and market demand is driving deployment regardless of federal policy changes.
Battery storage will continue its rapid expansion, enabling higher penetration of solar and wind on the grid. As storage costs fall further, renewable portfolios will increasingly operate like traditional power plants, charging during abundant generation and discharging during peak demand.
The 86 gigawatts of new capacity planned for 2026 represents just one year of a multi-decade transformation. With solar the cheapest source of new electricity in most markets and batteries solving intermittency challenges, the path forward is clear.
The milestone of renewables surpassing natural gas in installed capacity will formalize what market forces have already determined: clean energy is not the future of American electricity. It is the present.
