UK power supply squeeze eases as grid lifts warning

The grid had said late on Monday that it needed another 600 megawatts of capacity to maintain its safety cushion of spare generation between 0800 and 1700 GMT on Tuesday.

But in a note on the power market's Balancing Mechanism website it said the warning was cancelled.

Power prices in the traded market on Monday hit their highest levels since market reforms in 2001 as a series of outages at power stations forced the grid to warn that it was struggling to hold the safety cushion.
