EIA: 99%+ of new US capacity in 2026 will be solar, wind + storage
Solar, wind, and batteries are set to supply virtually all net new US generating capacity in 2026, according to the latest EIA data.
New U.S. electric generating capacity expected to reach a record high
U.S. power plant developers and operators plan to add 86 gigawatts (GW) of new utility-scale electric generating capacity to the U.S. power grid in 2026 in our latest Preliminary Monthly
Solar Integration: Solar Energy and Storage Basics
Short-term storage that lasts just a few minutes will ensure a solar plant operates smoothly during output fluctuations due to passing clouds, while longer-term
Solar, storage to lead record 86 GW of US capacity in 2026
Solar and battery storage are set to account for 79% of 86 GW of new utility-scale capacity planned in the United States in 2026, marking the largest annual increase in more than two decades
Wind and solar need storage diversity, not just capacity
The storage challenge behind variable renewables In practice, energy storage is often oversimplified as a tool for “capacity compensation”—the idea that merely increasing the scale of storage can bridge
Wind and solar need storage diversity, not just capacity
In 2024, the world added 585 GW of new renewable energy capacity, an all-time high, with wind and solar accounting for 96.6% of the total.
U.S. Grid Energy Storage Factsheet
Energy storage boosts electric grid reliability and lowers costs, 47 as storage technologies become more efficient and economically viable. One study found
Average and Marginal Capacity Credit Values of Renewable
Across technologies, capacity credits of solar PV most clearly follow downward trends over time, reflecting the significant rise in solar PV generation share in the projected future of the U.S. grid.
Why doesn''t solar power generation store energy?
Energy storage remains one of the most significant challenges in solar power generation. Unlike fossil fuels, solar energy is intermittent, reliant on
Solar-Plus-Storage: Fastest, Cheapest Way To Meet
Many utilities have embraced gas, or promoted restarting closed coal or nuclear plants, but that overlooks the cheapest and fastest-to-build
