South West Water achieves OFWAT leakage performance levelSouth West Water has joined forces with NewEnCo to install the UK's first revolutionary combined heat and power (CHP) Turbec turbine unit to run on biogas at Kilmington sewage treatment works.
The new state of the art CHP unit was commissioned in May and produces heat required for the treatment process and for the site offices as well as more than enough green electricity to operate the works.  South West Water achieves OFWAT leakage performance level The turbine has produced 132,000 kWh of electricity in just two months - that's enough to supply 105 homes and any surplus electricity is sold back to the national grid. Biogas is a by product of the sewage treatment process and recognised by the Government as a clean renewable energy source. It is produced from sludge which is settled out of waste water during the treatment process and after further heat treatment it releases biogas used to generate energy. The processed sludge can then be used on agricultural land as fertilizer. The new unit upgraded and replaced redundant equipment. It is supplied, monitored and maintained by NewEnCo and can be remotely controlled via the internet to ensure maximum performance. This energy is completely clean and renewable and saves South West Water over £30,000 a year on electricity costs. South West Water buys the green energy from NewEnCo at a discounted rate and sells the Renewable Obligation Certificates to energy suppliers in order for them to meet their renewable energy targets set by the Government. This is the first gas turbine CHP unit in the UK and probably the world to be run successfully on biogas and other companies have now adopted this method of green energy generation. Due to the success of this project South West Water will be installing another CHP unit at Totnes sewage treatment works in October. "The company is committed to using renewable energy wherever possible," said Alan Burgess, South West Water's Energy Manager. "This advance in new technology will protect the environment while encouraging other companies to adopt cleaner more cost effective energy generation methods". - END - For further information please contact Dina Chandler, Communications Officer on 01392 443021.
