About Ylem Energy Ltd

Our History

Ylem Energy Ltd is a leading independent power generation specialist, founded on its ability to generate energy from biogas fuels sourced from landfill and AD processes.

Over the past 25 years, we have developed and operated landfill gas-to-energy projects in the UK, Spain, Poland, Hungary, Lithuania, Morocco, Mexico and South Africa. Our team is committed to finding new and innovative solutions to manage gases efficiently in order to generate energy, reduce carbon emissions and meet relevant environmental requirements.

Whilst our business has historically focussed on producing electricity from biogas fuels, our enviable experience has led us to extend our capabilities to meet the needs of all types of gaseous-fuelled reciprocating generation and associated systems.

With such experience, coupled with our technical and commercial capabilities, following significant investment in research and development, we have further extended our offering to encompass advanced flexible generation systems that enable better balancing of the grid and lower our energy-intensive clients’ reliance on importing costly peak power. This benefits the clients and helps ease the energy network’s transition to decentralised generation.

Why Ylem?

Ylem Energy has a proven track record of delivering projects in many countries around the world and is experienced with the complexities of integrating standalone utilisation projects into the national grid of the host country and selling power in complex markets.

Since our inception in the early 1990s, we have amassed an enviable experience that has delivered hundreds of megawatts of installed capacity and tens of millions of hours’ operation.

From the initial site visit and outline design, through to successful completion, Ylem Energy has the skills and capacity to carry out detailed assessments and derive the optimum solution for projects.

We are also able to deal with all the statutory authorities to ensure that local planning and permitting is progressed. Ylem Energy will provide the necessary finance for the project, and manage the construction works through to a successful commissioning.

Once built the project will benefit from Ylem’s long term in-house operating regime, where our skills and knowledge of our operating staff will be utilised to deliver efficient and productive performance.

Funding Options

Ylem Energy has long tradition of self-financing projects, both at the initial capital stage and throughout the project life cycle in support of the operational service and support requirements. This flexible approach is important to ensure small- to medium-scale projects, typical of the type developed by Ylem Energy, can be financed quickly without third-party involvement which would slow the process and perhaps become a barrier to the development of certain projects.

Ylem Energy prefers to build, own and operate projects for the long term and, as such, our one-stop -shop solution benefits all concerned.

Where we operate

Ylem Energy has always looked beyond the United Kingdom in pursuit of countries that can host projects and benefit from our extensive skill and knowledge base which has been developed over many years of success operations within the UK. This approach has led to the development of gas-related projects in many countries.

The management team at Ylem Energy is proud of its long history of successful collaboration with partners around the globe. Currently we have operations in the following countries UK, South Africa and Mexico. One of the huge benefits from Ylem Energy’s overseas presence is the transfer of skills and the creation of key employment locally, wherever Ylem operates.

It is always our intention to create locally managed and resourced businesses wherever it has the opportunity to develop projects. Additional to this Ylem Energy provides other benefits locally through participation with, or the creation of, charitable trusts so that some of the financial benefits of the projects can be used locally to benefit the surrounding communities. This is most evident in South Africa where our charitable trust, set up in collaboration with our joint venture partners, is providing key funding to local schools in Johannesburg.
