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.
Shifting solar power for several hours using flow batteries will quickly become economically viable if the energy storage systems are also allowed to provide other services, such as grid-balancing, one maker of the devices has claimed.
The output of a 16MW solar farm in Puerto Rico will be tied to an Aquion ‘saltwater’ battery, in one of the few current trials of moving solar power produced in the daytime to be used at night.
