Context

NESO, the government-owned operator of Britain's electricity network, published its winter outlook alongside an independent report into its practices. National Gas published a separate gas winter outlook.

The Eversheds Sutherland investigation was commissioned after whistle-blower allegations about record keeping and operational decisions. It did not substantiate them but raised governance and cultural concerns.
