The UK government plans to provide voluntary long-term fixed-price agreements to electricity producers who are not currently part of the Contracts for Difference scheme, aiming to address rising electricity costs.
The Wholesale Contract for Difference (WCfD) initiative will allow renewable energy producers to accept a predetermined price for the electricity they generate in return for relinquishing future wholesale income.
The program is set to be introduced later this year, with an allocation process expected to take place in 2027.
According to the energy department DESNZ, this approach will “reduce the portion of electricity affected by gas price fluctuations and incentivize generators to transition to fixed contracts that are not tied to unpredictable gas prices.”
It is estimated that approximately 30% of the UK’s renewable energy resources may qualify for the WCfD, allowing those under the previous Renewables Obligation scheme to trade their wholesale revenues for a fixed price CfD.
Additionally, London will increase the Electricity Generators Levy (EGL) from the current 45% to 55% to "ensure a greater share of the extraordinary revenues generated during gas price surges is available to the government for supporting businesses and households impacted by the Middle East conflict on the cost of living."
UK Energy Secretary Ed Miliband stated: “As we endure the second fossil fuel crisis in less than five years, it’s clear that the age of fossil fuel security has ended, and we must usher in the era of clean energy security.
"This is why we are intensifying our efforts on clean energy, to provide our nation with energy security and permanently lower bills.”
UK Prime Minister Kier Starmer remarked: “We must break free from the fossil fuel cycle – this will stabilize energy costs and relieve family budgets.
“When global gas prices soar, residents here shouldn’t bear the financial burden. Our objective is straightforward: alleviate immediate pressures on household expenses while developing a domestic energy system that shields families from global uncertainties in the future.”
UK Chancellor Rachel Reeves noted: “Diligent British families and businesses should not suffer from global gas price fluctuations while electricity generators enjoy significant profits.
“By transitioning generators to the competitive rates guaranteed through wholesale Contracts for Difference and raising the EGL to 55%, we will help sever the connection between high gas costs and elevated electricity prices, providing households and businesses with better protection against potential energy crises.”
