Demand turn-up has been “killed before it got going”, an industry member told New Power after the results of National Grid’s fixed tender for the service were announced.
In the tender, 138.6MW of fixed volume was accepted from tenders totalling 262.2MW. But that meant the system operator (SO) had procured just half the volume it had announced. The SO has to balance the cost of calling on demand turn-up against that of other actions, such as constraining wind power, which may be cheaper.
