Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, with reference to ADE's Electricity System Benefits of Heat Networks research paper, whether he is taking steps to reform planning arrangements to capture potential £1.2 billion annual savings in avoided generation capacity from the expansion of heat networks.

The Warm Homes Plan sets our strategy for upgrading buildings, including. the case for heat networks to decarbonise heat whilst reducing the cost of upgrading the grid. We estimate that heat network deployment will save £5-7 billion in avoided distribution network costs, even before flexibility is accounted for. ADE’s research adds to our understanding in this area.

Our Heat Network Zoning policy will ensure that heat networks are built where they are the lowest-cost low carbon option, whilst Regional Energy Strategic Plans will ensure a more strategic, joined-up approach to electrification at a distribution level.
