While it may seem like an obvious choice for US states to include energy storage into their Renewable Portfolio Standard (RPS) commitments, in reality, standalone targets and mandates for energy storage procurement have been preferred.

Seeking ways to optimise the use of clean energy, California network operator CAISO (California Independent System Operator) is considering the introduction of a load-shifting product that would incentivise storing peak energy for later use.

The requirement of nine hours of energy storage duration at a project touted as a possible replacement for a new natural gas plant in California makes it tough for the newer technology to compete on cost, an analyst has said.

California’s grid operations will be supported by the ramping of an estimated 3,000MW of energy storage, when a solar eclipse expected across the Pacific North-West of the US will cause PV generation to dip.

Stem’s virtual power plants (VPPs) have been utilised to provide emergency demand response services in California during a major heatwave.

In the first of a two-part blog series on the energy storage response to the infamous Aliso Canyon gas leak in California, Energy-Storage.News sets the scene of how the California Energy Commission and chosen system suppliers got their heads around solving a mammoth power shortage with many, many batteries, in a race against time.

Another energy storage system project expedited to meet the resource adequacy requirements of a California utility following the Aliso Canyon gas leak has been completed, Powin Corporation has announced.

The utility has integrated battery energy storage systems into California’s electricity market CAISO for the first time.

Adobe is among the participants earning revenues from what is claimed to be an energy storage industry first – a trial rewarding California storage system users for conferring benefits to the grid.
