  • STOR Tender 35 Results

    This file gives the results for the 35th tender round. Providers submit their prices for availability and utilisation during these tenders. We consider the value and costs of each submitted tender, and compare these with the economic costs of procuring the same volume of reserve from alternative sources. In addition, we may also consider a number of other factors, including the historic reliability and geographical location of a unit or site.
