If demand ends up being greater than forecast, or there is unforeseen generation unavailability, extra sources of power may be needed to manage the system. One form of reserve that is used to manage this is Short Term Operating Reserve (STOR), which runs from 20 mins - 4 hours after a frequency event occurs. These tender results show the outcome of the associated tender round for every STOR year available in that tender round. > ** Please Note:** This datafeed is **no longer being updated** as we are now procuring STOR via daily auctions.
