Under plans announced on Nov. 18, the United Kingdom will close its coal fired plants by 2025 and become the world’s first major economy to move away from coal as its primary power source.

To replace the energy produced by burning coal, the United Kingdom will turn to nuclear power and natural gas plants to complement intermittent renewable energy, Secretary of State for Energy and Climate Change Amber Rudd said.

"It cannot be satisfactory for an advanced economy like the UK to be relying on polluting, carbon-intensive 50-year-old coal-fired power stations," she said at the Institution of Civil Engineers.

Reuters reported that about a third of Britain's electricity came from coal-fired plants last year but many of the 12 still operating are old and due to close during the next decade under tightening European Union environmental standards.

Rudd said the government would begin a consultation next spring setting out proposals to close by 2025 all coal-fired power stations which are "unabated" - plants not equipped to capture and store their carbon emissions - and restrict their usage from 2023.

British power producer Drax announced in September it would halt investment in the country's only coal power station carbon capture and storage (CCS) project when it is completed.

A spokesman for the Department of Energy and Climate Change said details would need to be ironed out after consultation with industry.
Drax Group, operator of one of Europe's largest coal and biomass-fired power plants, could see the remaining coal units close two years earlier if the government sticks to the 2025 closure date, analysts at Jefferies said.

German utility E.ON operates a 2 gigawatt (GW) coal-fired plant in Nottinghamshire, England, which is fitted with pollution-reducing technology that means it could still be running in 2025 under current legislation.

“We firmly believe that coal-fired power stations which meet rightly rigorous UK and European standards should remain an important part of the UK’s energy mix,” a spokesman for E.ON UK said.

Rudd said the government is committed to meeting a legally binding target to cut carbon dioxide emissions by 2050 to 80 percent below 1990 levels.

“One of the greatest and most cost-effective contributions we can make to emission reductions in electricity is by replacing coal-fired power stations with gas,” Rudd said.

Gas plants emit almost half the amount of carbon dioxide per megawatt of power generated as coal plants.

World leaders gathered in Paris for U.N. negotiations to seek an accord to curb greenhouse gas emissions where some campaigners criticized the new emphasis on burning gas instead.

The government on Wednesday committed to hold three more auctions offering support for renewable power generation but did not set out how much funding would be available.
