Concessionaire sought for Granton Waterfront heat network

A plan of a proposed heat network in the Granton Waterfront of Edinburgh.

The deadline to bid to deliver the heat network is 19th June 2023.

The City of Edinburgh Council is tendering for a supplier to deliver a new low carbon heat network serving new and existing buildings in the Granton Waterfront of Edinburgh under a concession model. The concessionaire will be responsible for designing, building, financing, operating, and maintaining the heat network. 

The Granton Waterfront development is planned to deliver around 3,500 homes along with a primary school, a medical centre, and over 9,000 sqm of commercial space, with the first properties set to complete in September 2025. The heat network is planned to provide cost-competitive low carbon heat to these new properties along with existing properties owned by the Council and its partners, representing a total annual heat demand of circa 25,000 MWh.

The proposed technical solution for the heat network is a wastewater source heat pump utilising heat from sewers, with a ground-mounted solar PV array helping meet the system’s electricity requirements. The network is expected to extended to around seven kilometres. The estimated total value of the works in question is £200 million.

The successful tenderer will initially be appointed to work with the Council over period of circa eight months under a pre-development contract before a final business case for the project is made. Subject to final business case approval, the Council will then enter into a concession agreement with the successful tenderer.

Interested parties are requested to submit proposals by 19th June 2023. Further information can be found here.
