2 August 2010 – Pratt & Whitney Power Systems company Turboden is to supply a 5 MWe geothermal Organic Rankine Cycle (ORC) turbogenerator unit to the German utility SWM – Stadtwerke München – for use in its district heating network.
The geothermal plant is based on a two-pressure level cycle, fed with geothermal fluid at 140 °C and cooled by air condensers.
The plant will provide the existing district heating network, which is already fed by a 600 kWe Turboden biomass unit, with an additional 4 MW of thermal energy.
‘This 5 MWe geothermal plant is going to be an important benchmark for both Turboden and the European geothermal industry,’ said Paolo Bertuzzi, general manager of Turboden.
‘We are already having other negotiations in Europe and in other markets thanks to the support of Pratt& Whitney Power Systems.’
Start-up for the new plant is scheduled for the last quarter of 2011.
