KING'S LYNN HEAT NETWORK MAPPING STUDY

BOROUGH COUNCIL OF KING'S LYNN & WEST NORFOLK

BACKGROUND

d3associates was commissioned by the Council to undertake a Heat Mapping and Master Planning (HM&MP) study for the town of King’s Lynn to enable the Council to identify a potential low carbon heat network.

Initially, nine zones were identified within King’s Lynn, however, following advice from the Government’s Heat Network Delivery Unit, this was extended to the whole of the town, specifically incorporating 32 public sector buildings.

The prime aim of the study is to identify and categorise existing and future heating, cooling and power demands, assess the full range of potentially relevant low and zero carbon heat network supply technologies and explore potential energy centre locations and network routes

OUTCOME

To ensure the energy demand assessment was as accurate as possible, d3associates worked closely with the Council, using the latest information for existing and future development sites.

An extensive list of possible receptors was developed and their energy demand was established using actual data wherever available. Illustrative images were prepared to show the power, heat and cooling demands of identified zones and public buildings. In addition, images showing the locations of potential waste heat sources and significant constraints to developing a district heat network were also produced.

The potential waste heat sources were discussed alongside alternative low carbon energy sources and a short list prepared. The likely location of an energy centre was found adjacent to the River Great Ouse for the preferred solution, a water source heat pump.

Using Thermos modelling software, an initial network option was identified based on connecting the cluster of public buildings in the town centre, the college campus and the hospital.

The HM&MP report will be used as a basis for a Green Heat Network Fund (GHNF) application in order to undertake a thorough techno-economic feasibility study.
