Scotland faces energy paradox as grid limits force wind farm shutdowns

Scotland has emerged as a significant renewable energy producer, generating a record 38.5 terawatt hours of renewable electricity in 2025. With a renewable generating capacity of 17.9 GW, the nation achieved net electricity exports of 20.8 TWh, valued at approximately £1.7 billion by the Scottish Government.

However, infrastructure limitations have created an economic paradox. A study by the Resolution Foundation reveals that the Seagreen offshore wind farm, Scotland's largest, was inactive for 71% of its potential operating hours during 2024. Due to a lack of high-voltage cable capacity to transport electricity to southern England, the national grid frequently orders operators to shut down production to prevent overloads—a process known as curtailment.

Under current regulations, operators receive compensation for these forced shutdowns. In 2024, Seagreen received £65 million in compensation, funded through system charges on consumer energy bills. This situation results in a cycle where taxpayers fund renewable infrastructure, pay for its inactivity, and subsequently pay for fossil fuel plants to meet demand when wind production is halted.
