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 compatibility of his Clean Power 2030 target with current grid capacity constraints.
Answered by Michael Shanks - Minister of State (Department for Energy Security and Net Zero)
The Clean Power Action Plan set out the actions needed to deliver the Clean Power target, including the generation assets required and the network projects needed to transport homegrown power to homes and business across the country. This was based on advice from the National Energy System Operator that is informed by its analysis of current and expected future grid capacity constraints.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, what proportion of funding in the consolidated low income household energy efficiency scheme will be allocated to (a) private sector homes and (b) social housing properties.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
The Government’s Warm Homes Plan includes £5 billion targeted investment for home upgrades for low-income and fuel poor households. This will initially be delivered via the Warm Homes: Social Housing Fund (WH:SHF) and the Warm Homes: Local Grant (WH:LG), which support social housing tenants and low-income homeowners respectively. The WH:SHF has been allocated up to an extra £295 million for 2026/27, in addition to the £1.3billion previously committed. £500 million has been allocated for the WH:LG.
From 2027/28 onwards the Government intends to integrate these schemes into a single low-income capital scheme, shifting towards area-based delivery. The Government will say more about the evolution of our low-income schemes in Spring 2026.

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 recommendations 11 and 12 of the Nuclear Regulatory Review on the level playing field provisions in the EU-UK Trade and Cooperation Agreement.
Answered by Michael Shanks - Minister of State (Department for Energy Security and Net Zero)
We will present a full government response and implementation plan by end of February 2026, taking account of our national security considerations, and planning, environmental and court processes. The Review acknowledges that when reviewing the recommendations in detail and in considering implementation, we may conclude that some recommended outcomes could be better achieved by alternative means, or that delivery timescales must necessarily be adjusted.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, what recent estimate his Department has made of the proportion of curtailment costs borne by domestic consumers.
Answered by Michael Shanks - Minister of State (Department for Energy Security and Net Zero)
Data relating to curtailment caused by constraints including costs is provided in the National Energy System Operator (NESO) Annual Balancing Report at this link: neso.energy/document/362561/download. Constraint costs, as with other interventions taken by NESO to balance the electricity system, are recovered from consumers through Balancing Service Use of System Charges. Both domestic and non-domestic consumers pay these balancing costs, in proportion to their energy consumption. Although the most energy intensive industries receive additional support with these costs.
The current extent of grid constraints reflects years of underinvestment, with new network infrastructure development having lagged the expansion of new generation. We are already taking action to reduce constraints with the biggest upgrade to Great Britain’s electricity network in decades.
Asked by: Connor Naismith (Labour - Crewe and Nantwich)
Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, what assessment his Department has made of the potential impact of introducing zonal electricity pricing on (a) consumer energy bills in regions with high renewable generation, such as those with significant offshore wind capacity, (b) the cost to the public purse of constraint payments to wind generators and (c) future private-sector investment in energy infrastructure in areas of high demand, including the South East.
Answered by Michael Shanks - Minister of State (Department for Energy Security and Net Zero)
In July 2025, we announced that we would not be implementing zonal pricing as part of the Review of Electricity Market Arrangements (REMA) and had decided instead to retain a single Great Britain wide wholesale electricity market. We plan to set out the potential impact of zonal pricing − with respect to areas such as consumers, generators and investment, including South East England – in the REMA Cost Benefit Analysis (CBA), which will be published later this year.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, how often gas-fired power stations were used to replace curtailed renewable generation in 2025.
Answered by Michael Shanks - Minister of State (Department for Energy Security and Net Zero)
The Department does not hold the requested information. It is owned by NESO and published on the Elexon data portal.
Asked by: Perran Moon (Labour - Camborne and Redruth)
Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, how much funding within the consolidated low income household energy efficiency scheme will be ringfenced for community level low carbon heat technologies, including (a) Shared Ground Loops and (b) heat networks.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
The Government’s Warm Homes Plan includes £5 billion targeted investment for home upgrades for low-income and fuel poor households. As part of this offer, from 2027/28 the Government intends to integrate the Warm Homes: Social Housing Fund and Warm Homes: Local Grant into a single low-income capital scheme, which will shift toward area-based delivery. The Government will say more about the evolution of our low-income schemes this Spring, including the scope of funded technologies.
In addition to any forthcoming funding from these schemes the Government is investing £1.1bn in low-carbon heat networks over this Parliament, and accelerating their rollout through Heat Network Zoning. We have also taken action to strengthen consumer protection through appointing Ofgem as the Heat Network regulator.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, what measures are in place to limit curtailment costs during the period before new grid infrastructure becomes operational.
Answered by Michael Shanks - Minister of State (Department for Energy Security and Net Zero)
The Government, the National Energy System Operator (NESO) and the Office of Gas and Electricity Markets (Ofgem) are pursuing measures which will reduce constraint costs in the short term. These include making best use of the existing network, deploying smart grid technologies and taking measures to reduce the amount of time networks need to be out of service for essential new build and maintenance. NESO is also progressing other technical measures at pace via the Constraints Collaboration Project. We intend to announce further measures in the Reformed National Pricing (RNP) Deliver Plan which will be published shortly.
