00:01Britain's Electricity Network operator says supplies are expected to remain secure throughout
00:05the winter, despite concerns raised by engineers. The National Energy System operator says the
00:11system is prepared for the challenges ahead, although some days could be tighter for supply.
00:16It says notices asking for power stations to make extra electricity available would
00:20be routine and would not mean power cuts were expected.
00:24The reassurance follows an independent investigation which found high levels of stress among control
00:29room staff concerned about keeping supply matched to demand. The investigation did not substantiate
00:35whistleblower's allegations but identified significant cultural, governance and control issues.
