Storage of electricity is not essential for reliability of supply on a power system with significant volumes of fluctuating renewable energy. Just as with coal, gas and nuclear power, reliability of supply from renewable energy can be secured from a range of generating options and from sophisticated management of both supply and demand. Grid stability is not reliant on storing electricity for later use. ...
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 2/5: Filling in for wind and solar over days of calm and cloudy weather is not a task storage can perform, even if it was a power system requirement
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
