UK's National Grid withdraws electricity system tightness warning for Wednesday

LONDON (Reuters) - Britain's National Grid has cancelled an electricity margin notice (EMN) for Wednesday evening after spare capacity increased.

National Grid is responsible for ensuring supply and demand are balanced in Britain's energy systems.

"We have enough generation to meet demand and continue to operate the system as normal," National Grid's Electricity System Operator said on Twitter.
