Warning on electricity capacity

Generator closures and breakdowns have led National Grid to warn that its capacity to supply electricity this winter will be at a 7-year low.

Spare electricity capacity, which ran at about 5% over the winter months last year, would be nearer 4% this year – three years ago the margin was 17%.

National Grid’s 2014/15 Winter Outlook report, is based on similar demand to last winter but a fall in supply. Since 2012, 15 power plants have been closed or partially closed. The company says it has contingency plans in place to manage supply, including paying big firms to switch off on cold winter evenings.
