Short Term Operating Reserve (STOR) is a National Grid service that can use your standby power system to provide additional power generation during periods of peak demand, allowing generator owners to reduce their total cost of ownership, or generate an extra income from new and existing hardware.
Payments can be made using an availability (£/MW/h) or utilisation (£/MWh) structure, giving you maximum flexibility when choosing how to best utilise your existing power generation systems. Typical terms (which can be tailored) provide the National Grid with run times of up to two hours per call, plus response time. Calls typically last around one hour and amount to approximately 50–60 hours of running per year.
For standby diesel generators, STOR is the largest incremental revenue opportunity, with the lowest relative impact on generator run hours and the lowest exposure to fuel price risk of any premium energy activity.
