The UK energy regulator Ofgem revealed on Monday that some power plants in the country may cease operations due to a gas shortage caused by the energy crisis, as per local media.

Citing the regulator, The Times reported that the UK could declare a gas supply emergency, which could cut off supplies to some gas-fired power plants, rendering them unable to generate electricity.

The state's declaration of emergency is likely to increase fears of blackouts because the UK relies on gas-fired power plants for most of its electricity supply, according to the newspaper.

Power plants will be fined if they fail to deliver as much energy as promised, according to the UK power industry rules.

Under power industry rules in the UK, the gas shortage should be addressed as soon as possible to avoid impacts on the safety of electricity and gas systems, as per the report.

The media outlet also warned that gas shortage should be addressed as soon as possible to avoid impacts on the safety of electricity and gas systems.

Ofgem said that the upcoming winter would be "more challenging than last year," as per the newspaper.

Because of the draconian sanctions imposed on Russia after February 24, the UK is currently facing a massive energy crisis.
