Lawyers to investigate claims of GB power grid cover-up over blackout risk

Operator brings in independent legal firm to look into whistleblower allegations relating to June heatwave

Great Britain’s grid operator has brought in independent investigators to look into accusations that its staff were involved in a cover-up over the power system being at a greater risk of blackouts during the heatwave.

The government-owned energy system operator will face the scrutiny of an external legal firm after a whistleblower claimed that control room staff were warned against leaving a paper trail relating to efforts to stabilise the power system during record high temperatures in late June.
