Objectives "The proposed solution method is to investigate the feasibility of heat extraction of community adjacent transmission cable head house(s), and to incorporate such heat extraction as part of the district heating solution design. The air temperature at the cable head house(s) is determined by the cable loading, which is usually at maximum during winter times, meaning that it is quite possible that there is enough heat to be recovered to keep the CoP of the ASHPs at high levels during winters and therefore keeping the electricity consumption at minimum. The heat recovery system could be installed at the most appropriate location inside the head house(s) to allow most efficient heat extraction. Identification of such locations is part of the feasibility study. The recovered heat could then be fed into a district heat network to provide heating for both space and water used by consumers.If successful, the proposed solution would be able to reduce the electricity demand by ASHPs in both summers and winters, therefore lowering the energy bills paid by consumers. This project proposes to perform a feasibility study to define the parameters required to enable this solution to be commercially viable, e.g., optimised equipment placement configuration in the transmission cable head house, ventilation shaft flow rate, primary heat pump output capacity, temperatures at various location of the heat loop, pipework costs, indicative system installation costs, etc.Data Quality Statement (DQS):The project will be delivered under the NIA framework in line with OFGEM, ENA and NGET internal policy. Data produced as part of this project will be subject to quality assurance to ensure that the information produced with each deliverable is accurate to the best of our knowledge and sources of information are appropriately documented. All deliverables and project outputs will be stored on our internal sharepoint platform ensuring access control, backup and version management. Deliverables will be shared with other network licensees through following channels:Closedown reports on the Smarter Networks Portal.Measurement Quality Statement (MQS): ‚ÄčThe methodology used in this project will be subject to suppliers own quality assurance regime. Quality assurance processes and the source of data, measurement processes and equipment as well as data processing will be clearly documented and verifiable. The measurements, designs and economic assessments will also be clearly documented in the relevant deliverables and final project report and will be made available for review.In line with the ENAs ENIP document, the risk rating is scored 6 = Low.TRL Steps = 2 (3 TRL steps)Cost = 1 (<¬£500,000)Suppliers = 1 (1 supplier)Data Assumption = 2 (Assumptions known but will be defined within project)" "The project is scoped into 2 phases. Phase 1: Feasibility study and scheme designProject inception and commencement meetingSite survey visitWorkshop 1: data collection & shortlist design optionsFeasibility study report for the projectWorkshop 2: design option confirmationRoyal Institute of British Architects (RIBA) Stage 3 design pack of the projectPhase 1 close out meetingPhase 2: Reference design for NGET specification integrationPhase 2 commencement meetingCollated package of RIBA Stage 3 reference design including heat recovery performance specification, generic layout, and schematic drawingsProject close-out meetingThe key aspects of each phase are:Core feasibility study (Phase1): Detailed analysis and feasibility study for the selected site in order to understand the heat recovery potential as well as how and to what extent the recovered heat can be integrated into a district heating solution that is commercially viable.Wider application & preparation for roll-out (Phase 2): Building on the learnings from Phase 1, an integrated reference design would be developed for heat recovery with both improvement in cable cooling and heat recovery. This aims to incorporate the design into NGETs design library, such that they could be easily adopted by NGET as part of the standard specifications for future projects to reduce overall build costs and to accelerate deployment.

Abstract With the need to decarbonise heat we need new and innovative ways of heat delivery that do not involve large infrastructure investment, high installation costs for consumers or high energy charges. The current solution is electrified heat via ASHPs[SA1
