Since 1 April 2021, participants who have an accredited shared ground loop system (SGL) or a ground source heat pump, can modify the capacity of their installation through the commissioning of additional ground source heat pumps; utilising their existing ground loop. For information on the eligibility criteria that must be met, please see Chapter 5 of our Guidance.
Following consultation, on the 21 February 2022 the Secretary of State was given the power to set new budget caps for SGL modified capacity (MC) applications in 2022/2023 and 2023/2024 on a sectoral basis; one covering ‘domestic’ applications and another covering ‘other’ applications.
To further control expenditure a shared ground loop MC budget cap of £4 million has been introduced for ‘domestic’ applications and £1 million for applications from ‘other’ sectors for 2022/2023.
The new budget allocation for plans to modify capacity in FY22/23 has been published by the Department for Business, Energy and Industrial Strategy (BEIS).
As part of our administration of the scheme Ofgem publish regular budget updates, to assist participants who have submitted a plan to modify capacity or are thinking about submitting one; to understand possible budget take up and allocation. The tables below display the status of the budget information for FY 21/22 (now closed to new applications) and 22/23.
Please note that the information in the tables below are not ‘live’ tables; they are a point in time data extract for the modified capacity portfolio. Due to the nature of the portfolio, plans are constantly being submitted and removed from the queue; therefore, the headroom available will change accordingly. We aim to update the tables on weekly basis on a Friday. They will therefore be representative of the portfolio up to midday on the Wednesday before.
The figures in the tables below are for information only and should not be used for the purpose of making any commercial decisions.
|Estimated total modified capacity allocated (based on plans received)||10,434,565|
|Estimated total modified capacity commitment (based on plans approved)||10,428,438|
|Remaining budget available (based on plans received)||4,565,435|
|Budget||FY22/23 (£) Domestic||FY22/23 (£) Other|
|Estimated total modified capacity allocated (based on plans received)||17,840||2,950,502|
|Estimated total modified capacity commitment (based on plans approved)||5,947||814,123|
|Remaining budget available (based on plans received)||3,982,160||185,877|
Note - The budgets for FY22/23 cover total potential expenditure calculated on the expected additional modified capacity notified following all modifications. The budgets for FY21/22 covered the total potential expenditure calculated on the total capacity of installations following all modifications.
