BEIS heat network zoning: modelling tool
According to the UK Government Department for Business, Energy and Industrial Strategy (BEIS), approximately 2% of the UK’s heat demand is currently supplied by heat networks, also known as district heating. The UK Government estimates a rise in the demand to 18% by 2050 with government support.
To accelerate the roll-out of heat networks, central and local government are collaborating with industry and local stakeholders to identify and designate areas as heat network zones, where low carbon heat can be provided at the lowest possible cost. Through designation and greater demand surety, BEIS anticipates that increased consumer and investor confidence in heat networks will lead to larger uptake and faster delivery.
In support of this policy, BEIS launched a pilot programme in England in January 2022 to develop, test, and refine different approaches to heat network zoning.
28 towns and cities across England participate in the pilot. Ramboll is leading the pilot in Bristol, Kingston-Upon-Hull and the London Borough of Barking and Dagenham.
In parallel and with support from Ramboll, BEIS is developing a modelling tool to provide an automated way of initial zone identification.
The project is split into two key stages (see diagram). In the first phase, the methodology and modelling tool will identify potential zones within each of the pilot cities using national datasets. Ramboll will then use a localised version of the tool to refine the results further.
Afterwards, Ramboll will conduct a techno-economic assessment of the proposed zones to establish the costs and benefits of large-scale heat network deployment. Establishing a robust data-driven evidence base is key to the successful rollout of heat network zone identification, which BEIS intends to deploy nationwide by 2025.
District heating for 1 million people
The 160 km transmission network supplying heat to Greater Copenhagen - heat for 1 million people - is one of the most sophisticated district heating systems in the world. It improves energy efficiency while reducing costs and environmental impact.
Meta: surplus heat to district heating
A Ramboll-designed energy centre is redistributing surplus heat from Meta’s data centre in Odense, Denmark, to the city’s district heating network. It's the largest Danish heat pump installation utilising surplus heat from a data centre.
Taarnby: city of smart solutions
The energy facility in Taarnby near Copenhagen, Denmark, is the world's first to combine district cooling and heating with wastewater, ground source cooling and a cold-water storage tank, resulting in cost-effective low-carbon energy for the district it serves.
