Prime Minister Rishi Sunak announced plans to construct new gas-fired power plants in the UK.
This move aims to bolster the nation’s energy security but faces criticism for potentially hindering the country’s net-zero emissions target.
The new plants are intended to replace aging infrastructure scheduled for retirement. However, the government hasn’t included carbon capture technology in the plans, sparking concerns from environmental groups. Opponents argue this could jeopardize the UK’s legally mandated goal of achieving net-zero carbon emissions by 2050.
Sunak, writing in the Daily Telegraph, defended the decision, highlighting the need for reliable backup power on days with low wind or solar generation. He portrayed these plants as an “insurance policy” for energy security while pursuing the net-zero transition.
Energy Security Secretary Claire Coutinho is expected to elaborate on these plans in a speech at Chatham House in London, marking a significant step in a comprehensive review of the UK’s energy market.
Here’s a rewritten version of the passage that maintains its length and structure:
Environmental groups have voiced concerns about the new gas plants. The Green Alliance think tank argues it directly contradicts the government’s ambitious goal of achieving zero-carbon electricity by 2035. The Energy and Climate Intelligence Unit expressed fears that declining North Sea gas production would leave the UK increasingly reliant on foreign gas sources.
The opposition Labour Party took aim at the ruling Conservative government, accusing them of locking the UK into another decade of high energy bills. Labour acknowledged the need to replace retiring gas-fired plants but criticized the Conservatives’ overall energy strategy.

Ed Miliband, Labour’s Shadow Energy Secretary, pointed out the government’s shortcomings:
“The reason the Conservatives can’t deliver lower bills and the energy security we need is because they consistently fail when it comes to building a clean energy future.” He further criticized the Conservatives for “clinging to the illogical ban on onshore wind, mishandling offshore wind auctions, and falling short on energy efficiency measures.”
This initiative prioritizes energy security and independence from foreign sources, particularly in light of recent geopolitical tensions.
The government maintains these plants will guarantee energy security, stabilize future electricity prices, and ultimately free the UK from dependence on foreign leaders like Russia’s President Putin. Sunak emphasizes this point, stating “A nation reliant on dictators for energy can never be truly safe.”
However, the plan isn’t without its critics. Environmental concerns remain, as these new plants will emit greenhouse gasses. The government acknowledges the future lies in renewable energy but argues it’s not yet dependable enough.
Therefore, the strategy involves replacing retiring gas plants with newer ones designed for a partially decarbonized grid. These plants will operate for short periods to fill gaps when renewable sources fall short. The government expects private investors to spearhead construction.
Looking towards the future, the government plans to modify legislation to ensure these plants can be retrofitted for cleaner technologies like hydrogen fuel or carbon capture and storage.
The government insists its plan aligns with the recommendations of the Climate Change Committee (CCC), the UK’s independent advisor on climate issues. The CCC previously stated that a “limited amount” of gas-fired generation, without carbon capture technology, could still be compatible with a decarbonized power system. Their estimate suggests this might only constitute around 2% of the UK’s annual electricity production.
