Minn. storage law may put pressure on gas-fired peakers

By Ethan Howland, American Public Power Association

Under an omnibus energy and jobs bill that was signed into law on May 31 utilities must assess how energy storage could meet generation and capacity needs as well as provide ancillary services. The bill includes several additional provisions aimed at jump starting energy storage in the state. When seeking to build power plants or power lines, utilities must show that energy storage cannot more cost effectively meet customer demand.

study released by the National Renewable Energy Laboratory in June found that a “substantial portion” of peaking capacity in the United States could be replaced by energy storage facilities. The capacity of the national peaking power fleet is about 261 GW and about 150 GW of that capacity is likely to retire over the next 20 years, NREL estimated. That could lead to the potential for about 28 GW of 4-hour battery storage that could serve as peaking capacity, NREL said. Read more here.
