Utilities: Batteries Are Most Generally Used for Arbitrage & Grid Stability

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 referred to as arbitrage, in accordance with new detailed info 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 top of 2028 based mostly 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 info on battery storage purposes, together with info on use instances, generator configuration, and different particulars on the power 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 can even make use of batteries to enhance grid reliability with providers that assist the transmission of electrical energy, referred to as ancillary providers. One kind of ancillary service is frequency regulation, which is the commonest use case reported no less than 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 goal of the battery. The early launch of the EIA-860 information is the primary time now we have printed this information aspect.
