## Summary

The Countess of Chester Hospital NHS Foundation Trust is in the planning stage of a procurement process for a deep geothermal heating solution. This initiative, set at their Chester location in the UK, falls under the 'works' industry category. The contracting authority is seeking to replace fossil fuel heating by drilling beyond 500 metres to harness geothermal energy. Suppliers are invited to engage in preliminary market engagement, with a key deadline for this phase set for 26th May 2026. The procurement initiation type is a tender, and engagement notices are already published, encouraging suppliers to participate.

This tender presents a significant opportunity for businesses specialising in geothermal energy projects and related services, such as drilling and engineering, to secure a long-term contract with a public health authority. Companies proficient in enhanced and advanced geothermal systems, energy-efficiency consultancy, and engineering design services are particularly well-suited. The procurement is open to SMEs, fostering competitive opportunities for smaller businesses to expand their market presence in the sustainable energy sector. As the project is above the procurement threshold, it promises substantial engagement and growth potential over the duration of the contract period, which is set to start in January 2027 and extend until the end of 2046.

## Notice

The Countess of Chester Hospital NHS Foundation Trust (The Contracting Authority) is seeking a suitably skilled supplier for a geothermal solution for heating the hospital, to displace fossil fuel heating. The successful Bidder is expected to take the project through a series of technical and project gateways so that an opportunity can be determined as efficiently as possible and then made bankable into an energy services proposal. The Contracting Authority's definition of a deep geothermal solution is defined as drilling beyond 500 metres below surface in order to harness higher temperatures. For deeper geothermal systems, technologies such as Enhanced Geothermal Systems (EGS) and Advanced Geothermal Systems (AGS) are utilised and are described as follows: EGS: involves improving the permeability of the rocks to create an artificial reservoir in geothermal settings where the subsurface temperatures are high but permeability is low. AGS: are deep, large circuits, with one or more wells drilled into hot rock with fluid circulating through a closed-loop system to bring heat to the surface. Drilling less than 500 metres is considered a shallow geothermal resource more commonly known as a ground source heat pump solution and for the avoidance of doubt, the Contracting Authority is not seeking proposals for this type of solution.
