The project is in its commercialisation (pre-procurement) phase, with grant funding secured for this stage. Karbon is supported by HNDC as commercialisation and technical adviser. ### The opportunity Karbon intends, in due course, to appoint a delivery partner, anticipated to be an Energy Services Company (ESCo), to transition heat generation from the existing gas-fired plant to a low-carbon solution. The solution is currently developed around large-scale water-source (river) heat pumps with thermal storage. The commercial and procurement structure is still being finalised, and this engagement will help inform it. This notice does not commence a procurement or call for competition. ### Scope of the soft market testing We welcome responses from organisations with capability across the design, build, financing and operation of district heat networks, including potential ESCo partners, EPC / DBOM contractors, and specialist sub-contractors. A Soft Market Testing Questionnaire is available on request and invites views on: - relevant experience and capability in comparable schemes; - appetite for delivery in a live, occupied, heritage-listed residential environment; - appropriate commercial and contracting structures, and parent company guarantee / security positions.
