EDF Energy has signed a long-term power purchase agreement (PPA) for the 11MW of anaerobic digestion/waste-to-energy facilities in UK, with Tamar Energy, a renewable energy company.

Under the terms of the PPA, Tamar Energy will sell the power generated from the five anaerobic digestion plants which are located at Basingstoke, Hants; Holbeach, Lincs; Retford, Notts; Halstead, Essex and Hoddesdon, Herts, UK, to EDF Energy.

Tamar Energy chief executive Willie Heller said: "Agreeing the PPA with EDF Energy, the UK’s largest producer of low-carbon electricity, is a landmark commercial achievement for Tamar Energy, which has quickly grown to be the UK’s largest AD company.

The company has already started selling power from its Basingstoke and Holbeach anaerobic digestion plants to EDF Energy in December, as part of the new PPA while the other three facilities are planned to enter service in 2015.

EDF Energy business services director John Cockin said: "This PPA provides a flexible way to sell energy into the market, so Tamar Energy can achieve the best price for their power and benefit from the minimum income certainty provided by the Feed in Tariff.

"We’re delighted this innovative approach suits both parties and enables Tamar Energy to achieve financial close for its power stations. We’re pleased to be Tamar’s long term partner and to support the expanding anaerobic digestion market."
