Finning UK & Ireland has marked a significant milestone by completing an overhaul on two combined heat and power (CHP) gensets at Shropshire Energy UK's anaerobic digestion facility located near Ely, Cambridgeshire. This state-of-the-art 3 MW facility is dedicated to transforming energy crops and vegetable byproducts into biogas, which in turn fuels three onsite CHP units. These units are essential for generating low-carbon electricity and heat for 48 climate-controlled mushroom growing tunnels, while any excess power is efficiently exported to the national grid.

Fred Clark, the managing director of Shropshire Energy UK, reflected on the relationship with Finning, noting that the engines had previously undergone a rebuild in 2021. This initial work had breathed new life into the units, which have since accumulated over 90,000 operational hours.

Given the critical nature of the facility's energy systems, which rely heavily on biogas production, maintaining dependable power generation equipment is paramount. Clark emphasized the importance of Finning's technical expertise and responsiveness, highlighting their ability to manage complex overhaul projects effectively, ensuring the facility operates at full capacity.

Daniel Newman Smith, customer account manager at Finning UK & Ireland, elaborated on the recent overhaul, which is part of their long-term commitment to supporting Shropshire Energy's CHP gensets. The E60 overhaul—a routine maintenance procedure carried out between major rebuilds—was executed in situ, allowing the engines to remain in their containers during the process.

Over a three-week period for each engine, worn components such as pistons, liners, big-end bearings, cylinder heads, filters, and spark plugs were replaced with genuine parts. This careful attention to detail not only rejuvenates the units but also optimizes oil consumption, extending their operational lifespan.

Moreover, Finning's support for Shropshire Energy does not end with the overhaul. The company has implemented a flexible service contract that encompasses monthly site visits, preventive maintenance, and management of third-party alternators. All servicing is performed by factory-trained engineers using authentic parts, with each intervention backed by a 12-month warranty, ensuring sustained efficiency and reliability for the facility’s energy demands.
