STOR

Reserve Power

STOR and the Capacity Mechanism is a National Grid scheme that offers to purchase reserve power from generators during periods of peak demand. This presents an exciting investment opportunity for businesses, landowners and investors.

Why do we need STOR?

Our grid is under increasing pressure to meet power demands during peak times. This pressure is only going to increase as 7GW of the UK’s existing coal generation was closed this year and a further 12GW is expected to close by 2025. National Grid uses reserve power during peak times to meet the spikes in demand and this reserve power is purchased via STOR contracts with a range of small to large private generators.

How does it work?

STOR is a contracted balancing service whereby the Service Provider delivers a contracted level of power, within pre-agreed parameters, when instructed by National Grid. The requirement for STOR varies depending on the time of day, week and year.
