The Siemens scope of supply for the biomass-fired plant encompasses an SST-800 steam turbine-generator. In addition to design, engineering and production Siemens will also install the turbine-generator. The plant will eventually be fired with a wide range of harvested wood and wood waste totalling around 400 000 tonnes per year.
6 May 2010 – Siemens Energy has received an order from Aker Solutions to supply a steam turbine-generator for what will be the largest biomass-fired CHP plant in the UK.
As the EPC contractor, Aker Solutions will design and build the power plant adjacent to the Tullis Russell paper mill in Scotland under contract to the RWE npower renewables, the UK subsidiary of RWE Innogy.
Following the start of commercial operation scheduled for late 2012, the power plant with a capacity of 50 MW will provide an efficient, low-carbon supply of power and process steam to the paper mill.
