Electrical energy utilities more and more report utilizing batteries to maneuver electrical energy from durations of low costs to durations of excessive costs, a method generally known as arbitrage, in line with new detailed data we lately printed.
On the finish of 2023, electrical energy utilities in america reported working 575 batteries with a collective capability of 15,814 megawatts (MW). We count on U.S. battery capability will greater than triple, including 35,953 MW by the tip of 2028 primarily based on plans reported to us by utilities.
We lately printed an early launch of information from our EIA-860, Annual Electrical Generator Report, which incorporates new detailed data on battery storage purposes, together with data on use circumstances, generator configuration, and different particulars on the vitality capability of deliberate batteries.
Utilities now report that arbitrage is the first use case for 10,487 MW of battery capability, making it probably the most reported main use. In arbitrage, utilities cost batteries by shopping for electrical energy throughout low-cost durations after which promote that electrical energy when electrical energy costs improve.
Utilities may also make use of batteries to enhance grid reliability with providers that help the transmission of electrical energy, generally known as ancillary providers. One sort of ancillary service is frequency regulation, which is the most typical use case reported a minimum of as soon as for battery capability.
Most batteries are utilized in a number of methods and have been reported in prior information releases, however we lately started asking utilities to determine the first function of the battery. The early launch of the EIA-860 information is the primary time we’ve got printed this information ingredient.
