Siemens Energy has received an order from Aker Solutions to supply a steam turbine-generator for currently the biggest biomass-fired combined heat and power plant in the UK. Aker Solutions is a global provider of engineering, procurement, construction and commissioning services to the natural resources and energy markets. 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 power 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 megawatts will provide an efficient, low-carbon supply of power and process steam to the paper mill.

The Siemens scope of supply for the biomass-fired power plant encompasses an SST-800 steam turbine-generator. In addition to design, engineering and production Siemens will also install the turbine-generator.

The biomass-fired power plant will eventually be fired with a wide range of harvested wood and wood waste totaling approximately 400,000 tons per year.
