Development & Funding Partner to develop the Birkenhead Heat Network
Authority: Wirral Borough Council (Local council)·On behalf of: CARBON TRUST ADVISORY LIMITED
What is being bought
Published requirement descriptionThe project comprises development of a new heat network serving a mix of buildings including new build residential, existing residential, new build commercial and existing commercial.
The project forms an integral part of Birkenhead 2040 Regeneration Framework; one of the biggest brownfield redevelopment sites in the UK. This regeneration of Birkenhead will take place across nine areas providing 21,000 new homes and almost 1,000,000 square metres of employment space over the next 20 years.
The area to be served by the network has been identified as a 'priority district heating zone' in Wirral's Local Plan. It will make a significant contribution to reducing the carbon impact of new / existing development in the Borough and provide opportunities to residents and businesses for lower cost heating.
The project is well-aligned with regional policy objectives and initiatives. It also fits into the Government's introduction of 'heat network zoning', which, through implementation, will mandate certain types of buildings in identified urban areas such as Birkenhead to connect to district heating within a prescribed timeframe.
It is envisaged that, once heat networking zoning is in place, the Birkenhead Heat Network could benefit from zoning 'incumbency' rules - meaning that nearby eligible buildings will be mandated to connect, further securing demand.
The Council and Development Partner will enter into a Development Agreement under which the Development Partner will further develop its proposals for the heat network.
The Development Agreement sets out a number of requirements which the project must meet in order to proceed into an approvals gateway process. If the project proceeds beyond the development period (i.e. is "approved" as part of the approvals gateway process), the Council and Development Partner will become shareholders in the ESCo, albeit that the Council's shareholding will be limited to a "Golden Share".
The ESCo will be the supplier of heat to a number of public and private sector bodies (including the Council) under separate heat connection and supply agreements. The Council will not be investing in the project. The Golden Share will simply allow the Council to exercise control in relation to a limited number of reserved matters including carbon intensity, reporting and tariffs. The ESCo will be required to source all capital funding for the project. The ESCo partner will be appointed in perpetuity.
The revenue derived over the first 40 years of the network is estimated to be in the region of £200 million (excluding VAT) / £240 million (including VAT) - £250 million (excluding VAT) / £300 million (including VAT). This includes all phases and connected buildings in the core scheme and allowing for further expansion with the wider geographic area. The estimated value cannot be guaranteed.
As part of the operation and expansion of the project, a range of customers in the Birkenhead area may seek to use the heat network, including a mix of public sector and private sector entities. It is intended that this project will be available to those other entities. Those entities may include:
Sixth form colleges
Central government departments (responsible for local offices)
Higher education organisations
NHS Primary Care bodies
Pursuant to Section 51 of the Procurement Act 2023, the Council must allow a minimum of eight working days, starting the day this contract award notice is published and the award of the contract.
- How the procedure runs: This Competitive Flexible Procedure will be conducted in five (5) stages. The stages consist of: Stage 1: Conditions of Participation Stage 1 commenced with the issuing of this Tender Notice and the publication of the Invitation to Tender (ITT). The ITT includes a Procurement Specific Questionnaire ("PSQ") at Appendix D: Procurement Specific Questionnaire which all Suppliers are required to complete and return in accordance with the Procurement Timetable and instructions within the ITT. Wirral Council will undertake a review of the completed PSQ with reference to any information held on the Central Digital Platform. Responses to the Conditions of Participation will be assessed in accordance with Appendix D: Procurement Specific Questionnaire. Further details of this are set out in Section 13 (Conditions of Participation) of the ITT. The assessment of these responses will identify up to three Suppliers to be invited to participate in Stage 2. The process for identifying the three Suppliers is set out in paragraphs 13.13 and 13.14 of the ITT, together with minimum score requirements in 13.12. Stage 2: Interim Tender Response Phase (incorporating initial dialogue meetings) Suppliers shortlisted at Stage 1 will be invited to an initial meeting. The anticipated agenda for the initial meeting is as follows: (a) introduce the Promoter's Officers and commercial, legal and technical advisors; (b) meet the Supplier's Team; and (c) to discuss/answer questions on the core elements of the scheme. Following the initial meeting, Suppliers will be required to submit an Interim Tender Response in accordance with the instructions set out in the ITT. The Interim Tender Response shall consist of a detailed mark-up of the Contract Documentation and a commentary table explaining the rationale of the mark-up. Interim Tender Responses will not be formally evaluated but verbal feedback will be provided to Suppliers during dialogue meetings. Stage 3: Dialogue Meetings It is expected that there will be two dialogue meetings with each Supplier. The purpose of the dialogue meetings is to discuss Suppliers' comments and proposed amendments to the draft Contractual Documentation. Further detail on the agenda for the dialogue meetings is set out in paragraph 7.3 of the ITT. If required, a third dialogue meeting may be held with each Supplier. Wirral Council may refine the award criteria in the ITT during or following dialogue meetings with Suppliers. If Wirral Council refines the award criteria, it will notify all Suppliers to any changes made to the award criteria when issuing the Invitation to Submit Final Tenders (ISFT). Stage 4: Invitation to Submit a Final Tender Response Suppliers will be required to submit their Final Tender Response in accordance with the instructions set out in the ISFT. Suppliers must respond to all of the Technical, Commercial and Social Value questions set out in Appendix B: Award Criteria of the ITT. Suppliers' Final Tender Responses will be evaluated in accordance with the assessment methodology set out in Appendix C: Assessment Methodology of the ITT. Wirral Council will conduct an assessment of all Final Tender Responses in order to identify the Supplier which has submitted the Most Advantageous Tender. Stage 5: Preferred Supplier Stage Following conclusion of Stage 4, the Promoter will provide an assessment summary to all Suppliers that submitted Final Tender Responses to: inform them whether they have been successful in the Procurement; provide an explanation of the assessment of the Supplier's tender against the relevant award criteria, in accordance with the requirements of the Act; where different to the Supplier concerned, provide information in respect of the Most Advantageous Tender submitted, including details of the assessment of this tender against the relevant award criteria and the Supplier's name; and engage in further discussions with the Supplier who the Promoter considers to have the Most Advantageous Tender (the "Preferred Supplier") in order to finalise the Contractual Documentation, in accordance with the limitations set out in the Act. Notwithstanding the above, Suppliers should note that any further discussions held with the Preferred Supplier will be solely for the purpose of finalising the Contractual Documentation based on their Final Tender Response and will not be an opportunity for further negotiation.
