## Summary

The NHS Wales Shared Services Partnership - Procurement Services, hosted by Velindre University NHS Trust, has completed the procurement process for the "Combined Heat and Power (CHP) Upgrade Works" as part of the Cardiff and Vale University Health Board's infrastructure. Based in Cardiff, the contract involves a major service upgrade to existing CHP systems that have been operational for over 16 years, having run for more than 90,000 hours. This direct award contract was granted to Clarke Energy, the Original Equipment Manufacturer (OEM), due to their extensive expertise in maintaining the system. The procurement was conducted under a direct award method for technical reasons, and the contract has been signed with Clarke Energy as of 9th December 2025, with a value of £672,000 gross. The work is expected to run from 10th December 2025 to 31st March 2026, specifically within the region of UKL22, United Kingdom.

This procurement presents significant opportunities for businesses involved in utility services, particularly those dealing with high-level maintenance and upgrades of specialised equipment. Companies similar to Clarke Energy, which possess expertise in energy systems, can find opportunities for growth by forming collaborative partnerships or delivering specialised maintenance services. The tender demonstrates the importance of having specialised knowledge and experience in the maintenance and improvement of energy systems, catering predominantly to providers able to work with complex systems requiring an in-depth understanding of technical and operational challenges. While the direct award limits competition, it underscores the significant role that established relationships and proven expertise play in winning such tenders.

## Notice

Cardiff and Vale University Health Board (CAVUHB) has had a contract in place for the last 16 years for a Combined Heat and Power (CHP) system. Recently a new maintenance contract has been put in place with the Original Equipment Manufacturer (OEM) as they are the only provider who can undertake works due to the specialised nature of the requirement. Both of the CHP's have now exceeded a run time of 90,000 hours and therefore a major service upgrade is required. As no overhaul has been undertaken in the previous 16 years, the risk of plant failure is increasing until these works are complete. It is proposed to upgrade one of the two CHP's at present and then run the second CHP on a decreased operating load to reduce the risk of plant failure. These works have been awarded to the OEM, Clarke Energy Limited.

### Procurement Information

Clarke Energy implemented the CHP system in 2008 and have since provided all associated maintenance for the system. Due to the complexity of the system and the fact that the CHP's have now run for over 90,000 hours, greatly increasing the risk of plant failure, only the OEM can perform the upgrades due to the relevant experience and knowledge they have gained on implementing and maintaining this system in the past 16 years.
