two.1.4) Short description
Construction and fit-out of a Heat Transfer Station (up to 37 MW capacity) on an EfW site comprising District Heating pumps, construction of a 7.5 km heat transmission main and supply and installation of 2 no heat transfer interfaces in East Devon.
The project is to connect the existing and yet to be developed parts of the Cranbrook/Skypark and Monkerton heat networks to a low carbon heat source at Hill Barton Business Park. When completed the project will provide low carbon heat to some 12,000 homes from an Energy from Waste plant which is currently under development. The Cranbrook/Skypark and Monkerton networks are designed to supply 3,500 homes and 1.4m sq ft of commercial space and 4,600 homes and 800k sq ft of commercial space respectively. The connection project will enable the bulk supply of heat to both networks. The interconnector will also support the planned expansion of the Cranbrook new town to circa 8,000 homes through enabling the delivery of a Future Homes Standard and Future Buildings Standard compliant energy solution.
It is currently anticipated that the Project will be split into two Lots:
- Lot 1 - Design and Build/Construction Package

Bidders will be able to bid for one or more Lots but are not obliged in any way to bid for both.
