Apr 15, 2026 - Why Is Britain Turning Off Its Own Wind Farms?



Scottish wind farms generate nearly half of Great Britain`s wind power, but in 2025, turbines there were paid £350 million to switch off. At the same time, Britain spent over a billion pounds firing up gas to replace it. The total bill: £1.35 billion. And it`s passed directly onto consumers in their energy bills.
Why are Britain`s wind farms are being turned off, how does this energy issue affect electricity bills and why is it getting worse? This is the story of grid constraints. What they are, why they happen, and why solving them is one of the most urgent challenges on the path to clean power.
In this documentary, we examine the infrastructure and market constraints behind Great Britain`s wind curtailment problem: the transmission bottlenecks between Scotland and England that cap how much clean power can flow south; the B4 and B6 grid boundaries where constraints are most severe; the role of the National Energy System Operator (NESO) in managing the grid in real time; and why gas still dominates over batteries when constraints hit.
We also look at the three routes available to fix the problem and why none of them are straightforward.
This is why Great Britain pays to turn off the wind - and what it would actually take to stop.
