The facility will process about 66,000 tonnes of unavoidable food waste per year, while producing energy to power 6,000 homes.
Tamar Energy is planning to develop a network of up to 40 plants in the UK by 2019.
Imtech said that it was selected to deliver this project due to its track record of effective Engineering, procurement and construction delivery of renewable energy projects in the waste and water sectors.
Tamar Energy construction and operations director Tony Wilson said, "The ex-power station site is exceptionally complex, with numerous challenges, including a flood plain location, ecological considerations, high pressure gas main through the centre of the site, adjacent 400kVa high voltage overhead power lines, in ground power lines and an adjacent historic asbestos landfill."
