Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what estimate her Department has made of the potential increase in (a) green levies, (b) market balancing and transmission costs and (c) other non-commodity costs that will be required to meet the 2035 target to decarbonise the electricity system; what assumptions her Department has made in making these estimates; and if she will make a statement.

The Department has produced a range of whole economy costs estimates to support decisions about energy transition and produces value for money assessments as part of every major decision. Minimising cost to consumers is at the heart of our strategy to deliver a reliable and decarbonised electricity system by 2035. The best way of protecting households and businesses is by lowering the costs of the energy we consume and reducing the volumes used. This means increasing energy efficiency and building out a low-cost, low-carbon energy system which reduces our reliance on fossil fuels.
