UK solar generation record falls amidst bright skies

National Grid’s ESO confirmed the news in a tweet, before confirming later that solar was providing more than a quarter (26%) of the country’s total power output at the time.The solar record is the latest in a spring of landmark achievements for the UK’s power system. Last week the UK celebrated going a whole week without coal generation for the first time since the Industrial Revolution, aided by substantial wind generation. Leonie Greene, director of advocacy and new markets at the Solar Trade Association, said that solar’s ability to meet big portions of electricity demand when skies are bright and temperatures mild was impossible to argue with.
