Renewables generated half of GB’s power in Q2

Renewable energy accounted for more than half of total electricity generation in the second quarter of the year.

Latest data showed solar also hit a new record of 8TWh of power during the period, contributing to the total 53% green power share.

Montel said wind remained Great Britain’s largest source of electricity generation, producing 18.9TWh during the quarter, up 7% compared with Q2 2025 and accounting for around 55% of all renewable generation.

“The generation mix continued to shift towards lower-carbon sources, with renewable generation accounting for more than half of total output,” said Phil Hewitt, director at Montel.

Fossil fuels contributed 23% of electricity generation followed by nuclear (13%).
