ENER-G expands CHP wastewater treatment and biogas team


ENER-G Combined Power has expanded its specialist CHP wastewater treatment and biogas team with the appointment of biofuels experts Martin Wager and Laurence Stephenson.

Martin joins ENER-G as Business Development Manager (Biofuels) from Cogenco. He has been involved in more than 40 CHP sewage treatment and biofuels generation projects over the past 12 years and has more than 30 years’ experience in the power generation and heat recovery industry, having started his career at East Midlands Electricity.

Laurence Stephenson joins the biogas CHP team as Sales Engineer from sister company ENER-G Natural Power, which specialises in landfill gas generation and bespoke anaerobic digestion (AD) projects.

ENER-G has manufactured, installed and operates in excess of 170 MW of biogas power generation, including wastewater CHP projects for South West Water, Severn Trent Water, Welsh Water, Wessex Water and United Utilities.

The company also designed and built a €2.6 million renewable energy centre at the Budapest wastewater treatment plant in Csepel – part of the Living Danube programme, which is one of Europe’s largest environmental investments.

Martin Wager said:

As water companies consider their AMP6 investment cycles, CHP from wastewater must be a priority. Such projects provide rapid pay back on investment – usually within 10 to 18 months. Considering that the lifespan of a typical CHP system is 10-15 years, this can provide a significant cash surplus, as well as improving environmental performance.

Water companies are eligible for feed in tariffs (FITs) on electricity generated from CHP engines and exported to the grid, while the heat can be used as part of the sewage digestion process. There is also potential for additional income via the Renewable Heat Incentive (RHI).

For the past 30 years ENER-G has been European market leader in small scale CHP (4 kWe to over 10 MWe). The UK company provides a complete package – from design and manufacture of CHP systems – to installation, commissioning and finance – through to maintenance and service via its national engineering team. It also supplies pre-treatment technology required to clean and dry biogas from digestion processes, such as effluent and AD.

ENER-G project manages and funds complete AD packages, or partners with AD specialists to provide digester gas generation technology and expertise for the back end of the process.
