US solar and ~~global~~ energy storage ~~and solar~~ expansion continues

The United States ~~continues its~~ is seeing rapid expansion in ~~utility-scale~~ solar and battery storage, ~~with capacity projected to reach nearly 65 GW~~ driven by ~~the end of 2026. In California, Wellhead Electric Company has completed the Stanton Battery Energy Storage System (SBES), a 275.2 MWh facility designed to capture excess renewable~~ rising energy ~~and displace over 40,000 metric tons of carbon dioxide annually. Domestic storage growth reached significant milestones in~~ demands from expanding data centers. In the first half of 2026, ~~with total installations hitting 30.8 GWh. This included~~ solar and storage technologies accounted for 70% of all new capacity added. Preliminary estimates from the U.S. Energy Information Administration (EIA) suggest developers plan to add a record ~~20.2 GWh~~ 86 GW of new large-scale generation capacity in to the ~~second quarter alone. Utility-scale capacity has nearly doubled from 88 GWh~~ grid in 2026, with solar projected to ~~165 GWh during~~ represent 51% of those additions. Between January 2025 and July 2026, renewables and battery storage expanded by 88.7 GW, significantly outpacing the 2.6 GW growth seen in fossil fuels and nuclear power. In the first 18 seven months of ~~the current administration, driven~~ 2026, renewable-generated electricity grew by ~~efforts to strengthen grid reliability and meet rising demand. Consequently, the Solar Energy Industries Association (SEIA) and Benchmark Mineral Intelligence have~~ nearly 11%, accounting for more than 29% of total U.S. electrical generation. This growth was led by utility-scale solar, which increased ~~their 2030 forecast~~ by ~~11.5%, now projecting~~ 22.0%. During this period, coal-generated electricity fell by 10.2%. The energy storage system (ESS) market reached a ~~total~~ record 18.9 GWh of ~~683 GWh. During~~ energy capacity deployments in the second quarter of ~~2026, the U.S.~~ 2026. While power capacity saw a ~~45%~~ slight year-over-year ~~increase in clean power additions, bringing cumulative~~ decrease, total energy capacity ~~to nearly 388 GW. Solar and~~ rose by 16% as the market shifted toward longer-duration battery systems. The average storage ~~together accounted for 70% of new electrical capacity. Solar capacity has now reached a major milestone, nearing 300 GW, which is sufficient~~ duration increased from 2.8 hours to ~~power more than 50 million American households. In Q2 2026, the solar industry installed 11.4 GWdc of new capacity, with~~ 3.5 hours. This trend is supported by utility-scale installations ~~accounting for 9.6 GWdc. While the commercial sector grew by 11%,~~ and a 48% jump in residential energy capacity. Analysts project annual ESS installations ~~saw declines. Additionally, offshore wind projects including Revolution Wind, South Fork Wind, and Block Island Wind are contributing 704 MW of electricity to~~ could grow by more than 50% over the grid. Recent reports indicate that solar currently supplies nearly 9% of total U.S. electricity generation. Developers have been accelerating projects to meet federal tax credit eligibility deadlines. New next five years as data ~~from the U.S.~~ centers seek rapid power solutions to bypass long lead times for new power plants and transmission lines.
