• Utility-scale battery vitality storage methods have been rising rapidly as a supply of electrical energy capability in the USA lately. Within the first seven months of 2024, operators added 5 gigawatts (GW) of capability to the U.S. electrical energy grid, in response to knowledge in our July 2024 electrical generator stock. In 2010, solely 4 megawatts (MW) of utility-scale battery vitality storage was added in the USA. In July 2024, greater than 20.7 GW of battery vitality storage capability was obtainable in the USA.
• Battery vitality storage methods present electrical energy to the ability grid and provide a spread of providers to assist electrical energy grids. Amongst these providers are balancing provide and demand, shifting electrical energy from durations of low costs to durations of excessive costs (a technique generally known as arbitrage), and permitting electrical energy from renewable sources, reminiscent of wind and photo voltaic, to be saved till wanted as an alternative of curbing these sources at occasions after they produce extra electrical energy than is consumed.
• Vitality storage methods usually are not main electrical energy sources, that means the expertise doesn’t create electrical energy from a gas or pure useful resource. As a substitute, they retailer electrical energy that has already been created from an electrical energy generator or the electrical energy grid, which makes vitality storage methods secondary sources of electrical energy. Vitality storage methods use extra electrical energy for charging than they supply when supplying electrical energy to the electrical energy grid. Secondary sources of electrical energy reminiscent of batteries are included in our Annual Electrical Generator Report and in our preliminary month-to-month electrical generator stock knowledge as a result of they supply the capability to satisfy load despite the fact that vitality storage methods don’t generate electrical energy immediately.
• Most U.S. utility-scale battery vitality storage methods use lithium-ion batteries.
• Our knowledge assortment defines small-scale batteries as having lower than 1 MW of energy capability. Small-scale battery knowledge are reported individually from utility-scale battery methods.
• Different forms of vitality storage methods embody pumped-storage hydroelectricity, flywheels, and compressed air. Extra detailed details about how batteries and these different methods work is obtainable on our Vitality Defined web page about vitality storage for electrical energy technology.
