Siemens Energy Service has been awarded a new order by PDM Widnes in Cheshire, United Kingdom (UK), for the performance upgrade of two small-scale steam turbines which power the company's carbon-neutral biomass combustion plants. The new contract with Siemens is focused on upgrades which will improve plant performance and enable PDM to qualify for Government CHP (combined heat and power) incentives. The contract is part of a larger plant modernization project. Commissioning is expected by the end of December 2012.
