## Summary

The Department for Energy Security and Net Zero (DESNZ) is commissioning the development of a primary National Zoning Model (NZM) under its Heat Network Zoning Framework, starting from December 2024 until April 2026. This project, titled "CON_7063 National Zoning Model - Primary Model Development," falls under the industry category of software programming and consultancy services (CPV code 72200000), with additional focus on research and development (CPV code 73000000). The procurement process is at the award stage, having been completed through a selective method, specifically a call-off from a framework agreement. The awarded contract, valued at GBP 641,145.53, was announced on 9th December 2024, with Environmental Resources Management Limited appointed as the supplier. This model will utilise various national and local datasets to optimise heat network zones.

This tender offers significant growth opportunities for businesses specialising in software development, data analysis, and energy consultancy. Companies with expertise in programming languages such as Clojure, and those capable of handling large datasets to model and optimise heating solutions, are well-suited to compete for such projects. Businesses in the energy sector can leverage this project to enhance their portfolio on national and international stages, particularly given the wide geographic scope of the model’s application, which includes the United Kingdom and other regions. Participation in this project could pave the way for further collaboration with DESNZ and other governmental bodies focused on decarbonisation and energy efficiency.

## Notice

1.1. The Department for Energy Security and Net Zero (DESNZ) is using Lot 3.1 from its Heat Network Zoning Framework to commission a primary National Zoning Model (NZM) developer from December 2024 until March 2026. 1.2. Model developers are required to further develop the NZM which has been built in collaboration with a range of organisations over the last 2-3 years. The model supports the identification of heat network zones (HNZs) in a standardised, consistent, efficient, and cost-effective manner. It produces maps and datasets describing the location and scale of indicative heat network zones. The indicative zones produced will be geographical areas where heat networks are expected to be the lowest cost technology to decarbonise heat used in buildings. 1.3. The model uses multiple national and local data sets to build up a granular building-by-building understanding of the likely heating demand, heat supply opportunities and routing constraints within each area. It then applies a range of national and local assumptions used widely across the industry to understand where heat networks are likely to meet the lowest cost, low carbon test outlined above. It uses a set of algorithms to perform calculations and optimise solutions at scale which would otherwise take months to generate manually. 1.4. The model is developed primarily in Clojure, at present DESNZ anticipate this shall remain the case for the duration of the contract. The codebase will be shared with all suppliers on Lot 3.1 from its Heat Network Zoning Framework under existing confidentiality clauses.
