Quick Summary

The cost of balancing Great Britain's power grid has reached nearly £50 million per day, with wind farms being turned off due to transmission bottlenecks. On Wednesday alone, the grid operator paid £47.9 million, including £1.6 million for one half-hour period, to manage supply and demand issues. These costs are among the highest since early 2022 and reflect growing concerns over insufficient infrastructure upgrades to support new renewable energy projects.

Story summary

The cost of balancing Great Britain’s power grid reached nearly £50 million a day in late October 2026. This surge occurred after wind farms were turned off due to transmission bottlenecks across the country. On Wednesday alone, £47.9m was spent, with one half-hour period costing £1.6m, some of the highest recorded since the early months of the Ukraine crisis in 2022.

These expenses follow a series of emergency measures by the National Energy System Operator (Neso), including seeking last-resort assistance from France to send power supplies on specific days. The cumulative costs for September hit £505m, marking the highest monthly cost ever recorded, and are projected to reach £3.2bn over the next year.

The escalating expenses highlight growing concerns about the pace of Great Britain’s £150 billion power networks upgrade failing to keep up with new renewable energy projects being integrated into the grid. On Wednesday, wind farms and hydropower plants capable of generating nearly 9 gigawatts were paid not to produce electricity, enough capacity to power more than 8 million typical households.

The cost of balancing Great Britain’s power grid has soared to near-record highs of almost £50m a day after windfarms were turned off because of bottlenecks in transmitting power around the country. asserted
windfarms → balance → country
The grid operator paid £47.9m on Wednesday to turn windfarms off in areas with an oversupply of electricity and turn gas plants on in areas where supplies were tight. asserted
supplies → pay → areas
The costs, which are levied on to household energy bills, included a £1.6m payment for one half-hour period, and were some of the highest recorded since the early months of the Ukraine crisis in 2022. asserted
