Balancing costs are projected to rise out to 2030, according to a new report from the system operator.
In its first Annual Balancing Cost Report, National Grid ESO said overall balancing costs in 2023/24 are £2.4bn compared £4.1bn in the previous year, partly due to lower wholesale energy prices and implementation of ESO initiatives.

Although wholesale prices have been a major driver of balancing costs in recent years, constraint costs are also rising due to significant changes to the GB generation mix, with up to 80 GW connecting by 2030 in its most ambitious decarbonisation scenario.
“Key decisions that will impact balancing costs include those considered in REMA, and those in Network Development, Connections, and new markets to aid balancing,” it said.
