In a report in The Times, we read that Energy bills set to rise after ship anchor severs power cables. Four of the eight interconnector cables between the UK and France are now unavailable until at least February. Coupled with an early cold snap, this makes the country’s energy safety margin very small indeed. In fact, with a number of French nuclear reactors being down at present, the chances are that we could not rely on our nearest neighbours to keep the lights on at times of peak demand.
Solar farms, of course, are contributing a few percent of total generation during the sunny weather, but will make no contribution at all to meeting peak evening demand. Wind farms will behave as they always do: generate electricity when the wind is blowing but not on demand. As The Times suggests, some mothballed coal-fired stations may need to be brought back on line this winter.
