Builders and energy plant homeowners plan to considerably improve utility-scale battery storage capability in the US over the subsequent three years, reaching 30 GW by the top of 2025, based mostly on the U.S. Energy Information Administration’s (EIA) newest Preliminary Month-to-month Electrical Generator Stock.
Builders and energy plant homeowners report working and deliberate capability additions, together with battery storage, to EIA via its electrical generator surveys. Battery storage capability in the US was negligible previous to 2020, when electrical energy storage capability started rising quickly. As of October 2022, 7.8 GW of utility-scale battery storage was working in the US; builders and energy plant operators count on to be utilizing 1.4 GW extra battery capability by the top of the 12 months. From 2023 to 2025, they count on so as to add one other 20.8 GW of battery storage capability.
The outstanding development in U.S. battery storage capability is outpacing even the early development of the nation’s utility-scale photo voltaic capability. U.S. photo voltaic capability started increasing in 2010 and grew from lower than 1 GW in 2010 to 13.7 GW in 2015. As compared, we count on battery storage to extend from 1.5 GW in 2020 to 30.0 GW in 2025. Very similar to solar energy, development in battery storage would change the U.S. electrical producing portfolio.
Battery storage provides stability to variable power sources corresponding to wind and photo voltaic. Wind and photo voltaic are each intermittent sources; they’ll solely present electrical energy when the wind is blowing or when sunshine is offered. Batteries remedy the intermittency drawback by storing further power produced by wind or photo voltaic turbines to be used later.
Greater than 75% of the 20.8 GW of utility-scale battery capability that homeowners and operators reported that they plan to put in from 2022 to 2025 is positioned in Texas (7.9 GW) and California (7.6 GW).
The big quantity of present and deliberate photo voltaic and wind capability in California and Texas current a rising want for battery storage. Extra utility-scale photo voltaic capability is positioned in California than in every other state, 16.8 GW, and builders count on so as to add one other 7.7 GW between 2023 and 2025. A complete of 10.5 GW of utility-scale photo voltaic capability is positioned in Texas; builders plan to put in one other 20.4 GW between 2023 and 2025. As well as, 37.2 GW of wind capability is positioned in Texas, greater than in every other state, and builders count on so as to add an extra 5.3 GW over the subsequent three years.
As extra battery capability turns into accessible to the U.S. grid, battery storage initiatives have gotten more and more bigger in capability. Earlier than 2020, the most important U.S. battery storage undertaking was 40 MW. The 250 MW Gateway Vitality Storage System in California, which started working in 2020, marked the start of large-scale battery storage set up. At current, the 409 MW Manatee Vitality Storage in Florida is the most important working battery storage undertaking within the nation. Builders have scheduled greater than 23 large-scale battery initiatives, starting from 250 MW to 650 MW, to be deployed by 2025.
