Short term operating reserve (STOR)

At certain times of the day we may need access to sources of extra power to help manage actual demand on the system being greater than forecast or unforeseen generation unavailability.

A STOR provider must be able to:

  • offer a minimum of 3 MW of generation or steady demand reduction. This can be aggregated from more than one site; and
  • sustain this response for a minimum of two hours.

Providers should be able to respond to an instruction from us within a maximum of 240 minutes, although response times within 20 minutes are preferable.
 

Providing STOR alongside other balancing services

It is not possible to provide other services at the same time as providing STOR.

Outside of STOR contracted availability windows, it is possible to provide other services, as long as doing so does not interfere with your ability to deliver STOR.
