One of the hidden costs of the transition to renewables is the cost of balancing the grid.
NESO are projecting a cost of £2667 million this financial year. Last year they originally estimated £3190 million, but this was overestimated and £864 million is being clawed back this year.

Taken over the two years as a whole, the total BSU0S charge averages £2960 million. That works out at £10.66/MWh.
NESO’s data shows how these costs have rocketed in the last decade.
[2024 and 2025 averaged together]
In April 2014, for instance, the charge was £1.84/MWh.
So since then, costs have risen by £8.82/MWh, equivalent to £2460 million a year.
