Glan Clwyd Hospital in Denbighshire, Wales is the district general hospital for the central area of North Wales. Built in 1980, it is situated in rural surroundings at Bodelwyddan, a small community that lies four miles south of Rhyl. The hospital serves a population of approximately 195,000. Demonstrating its expertise during a competitive tender process, YLEM proved it had the know-how to restore the hospital’s aging engines and re-establish a reliable heat and power source on site.


Inefficient CHP units were causing uncertainty with power supply

The hospital site, which lacks robust remote communications, was reliant on an aged plant including a couple of obsolete Dorman engines (since acquisition by Perkins) housed in the main hospital energy centre and an MAN engine located in a separate building. These engines were not being routinely maintained and hospital staff had to contend with a maintenance provider who tended to patch up failures rather than address the root causes, and kept no detailed service records. Therefore, the Hospital tendered for a new maintenance provider to deliver O&M service support to the site but had no allocated budget for any capital expenditure.

YLEM provided a full engine overhaul to get the Dorman engines back into a good working condition.

This was followed by comprehensive operations and maintenance (O&M) service support for all engines on site, including weekly housekeeping visits and remote monitoring. The initial overhaul costs were covered by YLEM investment with the cost to the hospital spread over the O&M contract term to mitigate the challenge of upfront capital expenditure.

We provide meticulous inspections, testing, and proactive maintenance with real time monitoring to help pre-empt any issues.

YLEM covered all of the upfront costs
Glan Clwyd can rely on YLEM’s experienced engineers for technical support and guidance.

A complete overhaul was completed to ensure the hospital had a reliable power source.


The hospital now has a single provider to support both the Dorman and MAN engines, which are running well and delivering reliable heat and power to the hospital.

  • Real time monitoring

    Potential issues are caught early due to good housekeeping, weekly, 24/7 support and the ability to diagnose and fix alarms or failures remotely.

  • Impeccable customer service

    YLEM has significantly improved the customer experience and has successfully rebuilt the hospital’s trust in its O&M provider. The staff at Glan Clwyd are confident that YLEM’s experienced engineers will provide them with technical support and guidance on other wider balance-of-plant systems on the site.
