Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential impact of zonal electricity pricing on (a) households and (b) businesses in Sussex.

The previous government consulted on various options to reform the electricity market and the government has committed to making a decision by the middle of 2025. We are developing further analysis to determine the impact of zonal or reformed national pricing on different consumers, geographical locations and businesses, working closely with the Department for Business and Trade.

The fundamental quantitative analysis will include scenario modelling of the electricity system to understand the wide-reaching impacts of market reforms. This will produce estimates of changes in the total electricity system cost and distributional consequences for consumer bills. This analysis will inform the final decision on market reform in mid-2025.
