What is being bought

Published requirement description

The London Borough of Tower Hamlets' current focus is exploring options for decarbonisation and expansion of the Barkantine Estate, to determine how the Heat Network can best deliver Tower Hamlets' existing and future customer energy needs, following an existing Private Finance Initiative (PFI) due to expire in October 2027.

This market engagement process is in advance of a future tender procedure to decarbonise, operate, and expand the existing Barkantine Heat Network. This will include financing, design, construction, provision of heat supply, customer relations, metering and billing, and operations and maintenance of the network. The existing district heat network has been in operation under a PFI agreement since August 2000, and serves a number of customers on the Isle of Dogs.

The Council are looking for a partner to support with evaluating options to decarbonise and expand the network, when the current management arrangements come to an end in October 2027. This includes options for utilising the existing energy centre or relocating to a new location.
