US electrical energies turn to batteries to shift power from low-price to high-price periods

Electric utilities in the U.S. are significantly turning to batteries to shift power from durations of low prices to highpriced ones, according to an analysis from the U.S. Energy Details Administration.

The strategy, described as arbitrage, involves utilities charging batteries by purchasing electricity during inexpensive durations and then offering that electricity when electrical energy prices boost. Arbitrage is now the main use case for 10,487 MW of battery capacity in the U.S., the EIA stated.

Energy storage innovations like batteries enable electric energies to keep power for later usage, handle supply and demand in genuine time, and assist avoid blackouts, among other usage cases.

Utilities are likewise utilizing batteries to boost electric-grid dependability, the analysis discovered. Other circumstances of battery usage include handling excess wind and solar energy on the grid.

Electric utilities in the U.S. were running 575 batteries, showing a total capability of 15,814 MW, at the end of 2023-- a figure that the EIA anticipates will more than triple by the end of 2028, with another 35,953 MW of battery storage contributed to the grid.

In California, for instance, battery storage on the grid has increase drastically after the state experienced rolling blackouts throughout a heat wave in 2020. In 2022, batteries accounted for 2.4% of generation during the evening hours of another heat wave, the California Independent System Operator reported.
