Technical FAQs 4

What is energy storage?

Energy storage is the capture of energy produced at one time for use at a later time. Without adequate energy storage, maintaining an electric grid’s stability requires equating electricity supply and demand at every moment.

What happens when the grid requires power?

When the grid requires power, the cars are released and move downhill to drive the electric motors for converting the potential energy back into electricity.

Can electrical energy storage solve the supply-demand balance problem?

As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system, Electrical energy storage (EES) technologies are increasingly required to address the supply-demand balance challenge over a wide range of timescales.

How does energy storage affect electricity prices?

Energy storage creates private (profit) and social (consumer surplus, total welfare, carbon emissions) returns. Storage generates revenue by arbitraging inter-temporal electricity price differences. If storage is small, its production does not affect prices.
