Understanding how electricity storage can competitively add value to power system management is key to assessing if and where there is a market for it as the transition to renewable energy progresses. Storage can potentially increase the range of options for meeting any or all of four principal requirements for reliable supply: provision of bulk power to make up for deficits in the variable output of solar and wind; system services (frequency response, reserves, voltage support) to provide increased flexibility in power system operation; management of variability to reduce price peaks and thus the cost of matching supply and demand; and easement of congestion on the network to reduce curtailment of green power production and defer spending on grid expansion. ...

Is electricity storage essential? Belief is a dangerous foundation for decision-making and beliefs about storage risk major investment errors
Special report - Electricity Storage part 3/5: By relieving grid bottlenecks of surplus supply and providing bursts of power when needed, storage can add sufficient value to find routes to profitability, but they are limited
Special report - Electricity Storage part 4/5: No means of affordably storing large volumes of electricity in all geographies exists, but a robust grid, connected over a wide area, can deliver green energy reliability
Special report - Electricity Storage part 5/5: The uptake of renewable energy does not increase the need for storage capacity, but stored power can help grid operators flexibly operate power systems, provided it can pay its way
