Gas Generation System Services

A comprehensive range of operation and maintenance services for all types of gaseous-fuelled, reciprocating CHP systems, generators and associated electrical infrastructure

Having operated gaseous-fuelled reciprocating generation systems since the early 1990s, we have gained an enviable amount of operational experience into just what is required in order to maintain the highest levels of reliability - even with the use of exotic gaseous fuels derived from sources such as anaerobic digestion and landfill - which can often present challenging conditions for engines. 

Our team of experienced engineers offer the following services:

Operation and maintenance

Operation, servicing and fault-finding for generating plant. This can be done via a competitively-priced long- or short-term contract, or simple ad-hoc basis.


24-Hour Call-Out Service

Offering round-the-clock service and support, our dedicated team of engineers are at hand to ensure your system’s integrity throughout the year

A complete service for generation systems

Generator refurbishment

Covering every aspect of a generator, we can work on-site or out-of-frame, providing full engineering and alternator overhauls. 

We approach this with a full project management service that includes the decommissioning and recommissioning process – including on-site lifting and haulage. In certain circumstances, we can also offer a swing unit to reduce downtime from the normal ten-weeks to less than one week.

Control systems

We can replace unsupported control systems -  or those with prohibitive OEM licence fees - with our own system that enables us to offer our clients a much more cost-effective solution, whilst retaining full control and management of the generation system.

Our intelligent, state-of-the-art remote generator management system minimises downtime and maximises operating benefits through trend monitoring, automatic resetting of minor trips and telemetry links to on-call engineers. Enhanced management of engine availability is undertaken on a daily basis, all year round.

Spare parts and service exchange

We have developed an extensive range of spare parts and service-exchange components. These include OEM, Non-OEM and also technically-advanced products that Ylem Energy has developed over many years of operation in arduous conditions, in conjunction with specialist partners. We have enviable experience in working with the major manufacturers such as Caterpillar, Perkins, MAN, MWM, and Jenbacher – along with smaller systems where required.

Electrical work

Our team is NICEIC-accredited and offers all services related to electrical systems. This includes:

  • Low-voltage electrical inspection and maintenance for energy centres and power generation facilities.
  • High-voltage transformer inspection and oil analysis, including annual inspection and testing as required
  • High-voltage switching to 11kV
