LONDON, Jan 26 (Reuters) - Britain's plan to close coal-fired power plants by 2025 has come under scrutiny from engineers who warned on Tuesday it could contribute to electricity supply shortages.
Under a business as usual scenario, the country's electricity supplies "can only be secured by granting an extension to existing coal-fired power stations," a report by the Institution of Mechanical Engineers said.
In a bid to meet its carbon emission targets, the government announced plans in November to close polluting coal-fired power plants and replace them with gas plants by 2025.
Coal plants provided more than a quarter of Britain's electricity in the first nine months of 2015, government data showed, and experts warn that new plants are not being built fast enough to compensate for the planned closures.
According to the report from the engineers institute, if the coal plant closures are combined with the shuttering of ageing nuclear plants there could be a supply gap of 40-55 percent, based on current typical supply.
"If we get to 2023/4 and the lights are flickering then of course you would expect the government to step in and say plants can stay open," said Peter Atherton, energy analyst at investment bank Jefferies.
The report said Britain would need to build about 30 new gas plants in less than 10 years to plug the gap, and that looks unrealistic given current weak electricity prices.
