Energy infrastructure business YLEM Group has launched YLEM Power, a specialist operations and maintenance company designed to support gas-generation assets across the UK, including biogas, landfill gas, anaerobic digestion and combined heat and power facilities. The new business will provide 24/7 support to energy asset owners and investors and will combine more than 35 field-based engineers with independent expert consultancy and £1 million of strategic spare parts and equipment.
The launch represents a new corporate development within YLEM Group’s UK energy operations as the company expands its focus on specialist maintenance and operational support for gas-generation infrastructure. According to the Bioenergy Insight report published on 2 October 2026, YLEM Power will operate across a range of gas-generation technologies while also supporting peaking power plants that can respond quickly to periods of increased national grid demand.
The report does not identify an individual journalist by name, so the information is attributed to Bioenergy Insight rather than assigning an unverified author. A separate report by Tim McManan-Smith of The Energyst, published on 1 October 2026, also reported the launch of YLEM Power and described it as a specialist gas-engine O&M company supporting UK energy assets.
What is YLEM Power and what will it provide?
YLEM Power has been established as a dedicated O&M business within YLEM Group. Its role is to provide operational and maintenance support for gas-generation assets throughout the UK, with the company targeting energy asset owners and investors.
As reported by Bioenergy Insight, YLEM Power will provide 24/7 O&M support to facilities covering combined heat and power, biogas, landfill gas and anaerobic digestion. Anaerobic digestion facilities convert organic waste into renewable energy, making the new business particularly relevant to operators whose assets depend on reliable generation and maintenance arrangements.
The business will also support peaking power plants. These facilities can generate electricity rapidly to fill gaps created when other sources are unable to meet demand, particularly during spikes in national grid requirements.
The Energyst’s Tim McManan-Smith similarly reported that YLEM Power would provide critical 24/7 support across combined heat and power, biogas, landfill gas and anaerobic digestion facilities, while also supporting peaking power plants.
How does YLEM Power differ from traditional gas-engine maintenance?
A central feature of the new business is the breadth of its engineering support.
Rather than concentrating solely on individual gas engines, YLEM Power says its expertise extends across the complete generator set and wider generating plant. This includes engines, alternators, control systems, high-voltage and low-voltage systems and other balance-of-plant equipment.
According to Bioenergy Insight, YLEM Group believes this approach can reduce the requirement for asset owners to appoint several separate contractors for different parts of a generating facility. Instead, more maintenance and engineering issues can potentially be addressed through a single engineering team.
The Energyst report by Tim McManan-Smith also highlighted this wider scope, noting that YLEM Power’s teams will support the entire generator set and associated generating plant rather than focusing exclusively on the gas engine.
For operators of biogas and anaerobic digestion plants, this broader approach can be relevant because plant performance depends on multiple interconnected systems rather than the engine alone. Maintenance requirements can involve generation equipment, electrical systems, controls, and other plant components.
Why is YLEM Group using its own operating experience?
YLEM Group is not entering the O&M market solely as an external engineering provider. The company already owns and operates several gas-generation assets across the UK, including biogas and anaerobic digestion sites.
The group says this operating experience gives YLEM Power an understanding of the commercial consequences associated with asset availability, downtime, maintenance decisions and lifecycle costs.
According to Bioenergy Insight, YLEM Power intends to combine engineering expertise with operational data and commercial insight. The company says this can help asset owners understand how their facilities are performing, protect uptime and seek to maximise long-term asset value.
The issue is particularly relevant to anaerobic digestion and landfill gas operators, where feedstock and output can vary, and maintenance scheduling must be considered alongside operational requirements.
YLEM’s existing experience is also illustrated by its work with Angus Energy. In a YLEM Energy case study, the company said it secured a five-year O&M contract for two gas engines supporting Angus Energy’s Saltfleetby B site after diagnosing and remedying problems with compressor skids. The case study says the engines were important to site production and that YLEM Energy’s support included control-system upgrades.
That earlier experience provides context for YLEM Group’s decision to establish a dedicated O&M operation, although the new announcement concerns the broader YLEM Power business rather than a new contract with Angus Energy.
What resources will YLEM Power have?
YLEM Power will begin operations with more than 35 field-based engineers, alongside independent expert consultancy capabilities and £1 million of strategic spare parts and equipment.
The combination is intended to give the company an operational base from which to provide maintenance support across the UK.
The availability of strategically held parts is particularly relevant to maintenance operations because equipment downtime can affect the ability of generating assets to produce electricity when required. YLEM Group says its existing experience and resources mean it is already equipped with people, parts and technical expertise to serve the market and expand the business.
Ian Gadsby, Chief Executive Officer of YLEM Group, told Bioenergy Insight that the company’s experience and specialist engineering team across the UK provide the foundation to serve customers and scale YLEM Power.
What did Ian Gadsby say about the launch?
Ian Gadsby said the creation of YLEM Power follows more than 12 months of restructuring within YLEM Group.
As reported by Bioenergy Insight, Gadsby said the restructuring and launch were intended to provide greater clarity around the group’s service offering while creating opportunities for growth in the O&M sector.
Gadsby also pointed to the company’s existing engineering resources and its position as an owner and operator of gas-generation assets.
He said YLEM Group can approach O&M decisions from the perspective of an asset owner because it owns and operates gas-generation facilities itself. The statement links engineering decisions with commercial consequences such as availability, downtime and operating costs.
The Energyst, in Tim McManan-Smith’s report, carried the same statement from Gadsby and similarly highlighted the group’s more than 12 months of restructuring, specialist engineers and plans to expand the O&M business.
How does YLEM Power fit into the wider YLEM Group?
YLEM Power will sit alongside other businesses within YLEM Group’s energy portfolio.
According to Bioenergy Insight, the portfolio includes Root-Power, a battery energy storage developer; Power Zero, a commercial solar energy specialist; and YLEM Energy, which will continue focusing on energy generation.
The structure places O&M alongside generation, solar and battery-storage activities, giving YLEM Group separate businesses operating across different parts of the energy infrastructure market.
The launch therefore represents more than the introduction of another maintenance service. It forms part of a wider restructuring of the group’s activities and creates a dedicated business focused on maintaining and operating gas-generation infrastructure.
What role could gas-generation assets play under Clean Power 2030?
YLEM Power’s launch comes against the backdrop of the UK’s planned transition towards a cleaner electricity system.
The UK Government’s Clean Power 2030 framework envisages a reduced role for unabated gas generation while retaining gas capacity as a strategic source of flexibility during the transition. Government material has stated that around 35GW of existing unabated gas reserve capacity is expected to be maintained while lower-carbon flexible technologies are developed.
The government’s response to its Capacity Market consultation stated that low-carbon flexible technologies, including carbon capture, usage and storage, hydrogen-to-power and long-duration electricity storage, are expected to expand. During that transition, around 35GW of unabated gas reserve capacity is to be maintained to protect security of supply.
A written statement published by the UK Parliament similarly said the Clean Power Action Plan envisaged continuing reliance on around 35GW of existing unabated gas until it can be replaced by lower-carbon alternatives providing the required flexibility. It also described a shift in the role of unabated gas from more regular generation towards strategic reserve use.
Against this backdrop, YLEM Group argues that reliable maintenance of gas-generation assets will remain relevant to the electricity system.
Why does YLEM Group see an opportunity in peaking power?
Peaking power is particularly relevant to the business because these facilities are designed to respond quickly when electricity demand rises, or other generation is insufficient.
According to Bioenergy Insight, YLEM Power will support peaking power plants that can rapidly generate electricity to cover gaps left by other energy sources during periods of increased national grid demand.
The role of flexible generation is also recognised in government policy. The UK Parliament’s published statement said the variable nature of renewable generation makes sufficient flexible capacity important to maintain electricity security, particularly when renewable output is low.
This provides the wider context for YLEM Power’s focus on asset availability and maintenance. If generating assets are intended to provide back-up during periods of system pressure, their ability to operate when called upon becomes an operational consideration.
Gadsby said YLEM Group expects peaking power plants to remain important to energy infrastructure and linked the company’s plans with the government’s Clean Power 2030 ambitions and the future stability of the national grid.
What does the launch mean for UK biogas and anaerobic digestion operators?
For the UK’s biogas and anaerobic digestion sector, the development introduces a dedicated O&M business with a focus extending across the wider generating plant.
The company’s proposed model brings together field engineering capacity, spare-parts resources and experience from operating gas-generation assets. According to Bioenergy Insight, YLEM Power’s objective is to help asset owners understand performance, protect uptime and manage long-term asset value.
For businesses operating renewable-energy generation from organic waste, the maintenance of generation equipment is one component of maintaining reliable output. YLEM Power’s approach covers the equipment surrounding the gas engine as well, including electrical and control systems.
The company’s launch therefore connects operational engineering with the commercial requirements of energy assets, while remaining part of a wider YLEM Group restructuring.
For organisations working across energy generation, maintenance and infrastructure, the operational issues raised by the launch also intersect with professional development in Power Systems and Maintenance, Oil and Gas, Environmental and Agriculture, and Management and Leadership, particularly where engineering reliability, energy assets, maintenance planning and operational decision-making overlap.
What did YLEM Group say about its long-term ambitions?
Gadsby said the group expects the new business to create opportunities within the O&M market and indicated that YLEM Power has been structured to scale.
As reported by Bioenergy Insight, Gadsby said the company already has the people, parts and expertise required to serve the market and expand its operations. He also said the group’s direct experience as an asset owner informs its understanding of the commercial consequences associated with operational decisions.
In a further statement reported by Bioenergy Insight, Gadsby said the company intends to help energy asset owners pursue long-term commercial success, particularly as peaking power plants continue to have a role in the UK’s energy infrastructure.
The Energyst’s Tim McManan-Smith also reported the company’s stated intention to use its existing UK engineering resources and expertise to serve and expand the O&M market.
The launch consequently places YLEM Power at the intersection of gas-engine maintenance, renewable gas generation, flexible power and wider energy infrastructure. Its immediate focus is operational: providing 24/7 maintenance support and engineering expertise to assets across the UK, while YLEM Group positions the business as part of its broader restructuring and growth strategy.
