The unit at the facility runs on a Government-backed contract under which Drax returns to consumers any profits it receives from market prices above a certain level.
But the company powered down generation at the unit as the energy crisis raised market rates for electricity in early 2022, according to Bloomberg.
If it had kept the unit running at full capacity, the company would have returned an estimated £639 million in profits to consumers, according to estimates by Bloomberg.
Not broken any rules
Three other units, from which Drax could keep all profits, were kept running at the time. There is no suggestion that Drax has broken any rules.
But Ed Davey, who was the Lib Dem energy secretary at the time of the contract negotiations, told the news organisation that Drax appeared to be “gaming the contract”.
If it was Ed who wrote the contract then the holes through which one could game would likely be pretty large.
