A residential battery storage system in New York State could soon earn on the order of $190 per year, when aggregated with other systems participating in the state’s wholesale capacity market. Storage system owners in other parts of the country may wait much longer.
Three regional grid operators and two utilities have joined the DOE partnership, alongside renewables developers and trade groups, to pursue faster, simpler, and fairer interconnection of renewables and storage, on both the transmission and distribution grids.
A new partnership that engages grid operators, utilities, clean energy developers, regulators, and DOE’s national laboratories aims to lower costs and reduce wait times for utility scale solar projects connecting to the grid.
“Climate change is one of the most destabilizing forces of our time, exacerbating other national security concerns and posing serious readiness challenges,” said Secretary of the Navy Carlos Del Toro, in announcing the target.
Higher natural gas prices call for more near-term solar, said Georgia’s solar trade group in testimony on Georgia Power’s proposed resource plan, adding that a utility cap on rooftop solar should be lifted. Two other groups challenged the utility’s modeling choices.
As Western and Southeastern utilities process 194 GW of solar interconnection requests, we asked 20 of them about the final cost studies they completed last year, which would permit projects to move forward. Then we turned to Berkeley Lab analyses for more insights.
For 24 states whose governors support climate action, reaching 100% renewable electricity by 2035 would cost less than a “no new policy” scenario, the Union of Concerned Scientists found.
“Given our climate crisis, state utility commissions must act with urgency and prioritize innovation in the way utilities are regulated,” says the Sunrun policy team in a paper. Noting great progress by Hawaii and Vermont, they also call for state regulators to “rethink” how utilities make money.
“It’s time for ISO-New England to get out of the way” of renewables, said Senator Markey. He and Senators Warren and Sanders have asked federal energy regulators to end an anti-renewables rule in New England formally known as the “minimum offer price rule.”
NREL’s final report on the future of storage, drawing from a series of six in-depth studies, presents “key learnings” from across those studies.
