A season to be proud of.

We pushed the boundaries over land and sea, and couldn't have done it without your support. Thank you, Gooners ❤️

Standing on the brink of history.

[National Energy System Operator @neso_energy]

Britain’s electricity system recorded its lowest ever transmission demand today: 12.62GW between 13:00–13:30.

Sunny weather, high solar generation and the bank holiday weekend all contributed to the lower level seen on the network. ☀️

The system operated securely throughout.

WE NEVER GIVE UP ✊

ANOTHER BIG STEP.

🧵 Record-breaking day for Great Britain's electricity system! ⚡

1/ On 22 April, we hit a new zero-carbon record, with zero-carbon sources providing 98.8% of our electricity.

On 25 March at 1:30pm, wind generated 23,880MW of electricity to set a new maximum wind generation record.

🥇At the time, wind was providing 60% of Great Britain’s electricity, that’s enough to power over 23 million homes.
