Grid Rules Need To Boost Battery Storage’s Stacked Values
California’s energy storage value ‘significantly’ boosted by stacking benefits, study says
Andy Colthorpe, 13 September 2017 (Energy Storage News)
“The value of a front-of-meter battery energy storage system in California could be doubled or even trebled, by adding more than one revenue stream to the project…[System designers and operators should widen their focus from single use applications, according to the] Brattle Group report, ‘Stacked benefits: Comprehensively valuing battery storage in California’…Modelling a large-scale energy storage system in California…[Brattle found] it could cost between US$200 and US$500/kW-year to deploy a 1kW / 4kWh battery…[But the benefits, when stacked, could be from US$280 annually to] US$328/kW-year. The biggest values are to be found in three areas: avoided capacity cost, frequency regulation and in energy price arbitrage…” click here for more
