KEY TAKEAWAYS ON GRID STORAGE .. .. Power system operators have for decades included modest volumes of stored electricity in the mix of options for balancing supply and demand, provided the value of the stored electricity has been greater than the cost of paying for it. .. The value of stored electricity is not necessarily increased by the uptake of high proportions of renewable energy. .. Balancing supply and demand can be done without using stored power, which rules out paying for storage solutions at any cost, also on power systems supplied with electricity from a mix of variable and dispatchable renewable energy sources. .. Storing electricity is always more expensive than using the same electricity directly. The fundamen ...

Is electricity storage essential? Belief is a dangerous foundation for decision-making and beliefs about storage risk major investment errors
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
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
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
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
A glossary of terminology used in electricity supply, power system management and grid services
Batteries score in their ability to rapidly inject bursts of electricity into the grid, but demand for the service is not greater in countries furthest ahead in transitioning to renewable energy
