Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what assessment they have made of the proposal in the report by Greenpeace and Stonehaven, Power Shift, published in March, to move gas-fired power stations into a Regulated Asset Base strategic reserve.

This government has been clear that the answers to the challenges around energy security, affordability and sustainability point in the same direction – clean energy.

Under current market frameworks, technologies with the lowest marginal cost dispatch first. Unabated gas generators have high marginal costs so generally dispatch last.

By 2030 unabated gas will account for less than 5% of total generation. As low‑carbon technologies are deployed at scale, gas will increasingly shift to a reserve role in the system, meaning it will set electricity prices less often over time, reducing consumers’ exposure to volatile fossil fuel prices.

As the role of unabated gas diminishes, we continue to work with NESO and Ofgem to explore how market and system arrangements can evolve to minimise its impact on consumer bills, including considering the potential benefits and risks of alternative market reforms.
