Britain has chosen to keep its newest operating nuclear plant running two decades longer, giving Sizewell B a path to generate electricity until 2055. Official EDF figures put the station at 1,198 megawatts, or about 1.2 gigawatts, and the plant currently supplies roughly 3% of the country\u2019s electricity needs.<\/p>\n\n\n\n

This is not a vote for nuclear power over renewables. It is closer to an insurance policy for a grid trying to reach at least 95% low-carbon generation by 2030 while building wind farms, solar projects, storage<\/a>, and power lines at the same time.<\/p>\n\n\n\n

A 20-year lifeline<\/h2>\n\n\n\n

Sizewell B began generating in 1995 and had been expected to close in 2035. Under the heads of terms signed by the government and EDF, the energy group plans to fund a refurbishment worth about $1.07 billion using the European Central Bank\u2019s reference exchange rate for July 8, 2026.<\/p>\n\n\n\n

The upgrades will be spread across planned outages over the next 15 years, reducing the need for one long shutdown. EDF says the extension could add about 180 terawatt-hours of electricity<\/a> and retain roughly 900 skilled jobs in Suffolk, while Ed Miliband, who was Energy Secretary when the deal was announced, called nuclear power \u201cvital for our energy security.\u201d<\/p>\n\n\n\n

How the price guarantee works<\/h2>\n\n\n\n

The proposed deal uses a 20-year Contract for Difference<\/a> beginning in 2035. Its strike price is roughly $94 per megawatt-hour in 2025 prices, while Centrica will support the investment through its 20% ownership stake in the station.<\/p>\n\n\n\n

The contract sets a reference price for Sizewell B\u2019s electricity. When the wholesale market price falls below that level, the Low Carbon Contracts Company pays the generator the difference, but when the market rises above it, the generator pays the excess back.<\/p>\n\n\n\n

The UK extends the operational lifespan of its last nuclear plant by 20 years to secure a steady low-carbon energy transition.<\/figcaption><\/figure>\n\n\n\n

There is an important catch. The long-form contract has not yet been completed, and the life extension still requires regulatory approvals, so this is a major milestone rather than the final legal word.<\/p>\n\n\n\n

Britain\u2019s nuclear handoff<\/h2>\n\n\n\n

Timing explains why Britain is extending an older plant while also building new reactors. Hartlepool and Heysham 1 are currently expected to generate until March 2028, while Heysham 2 and Torness are forecast to continue until 2030.<\/p>\n\n\n\n

EDF is organizing Hinkley Point C<\/a> around its first reactor starting in 2030. Sizewell C and the first Rolls-Royce small modular reactors at Wylfa are expected to add new capacity during the 2030s, but that schedule leaves little room for another major construction delay.<\/p>\n\n\n\n

Sizewell B therefore acts as a bridge across a fragile transition. It cannot replace every retiring reactor, but keeping 1.2 gigawatts online gives grid planners more breathing room and reduces pressure to fill a shortfall with imported electricity or additional gas-fired generation.<\/p>\n\n\n\n
