Products & Markets
Increasing prices of fossil fuels
Global warming
Political pressure on use of renewable energy
Increasing demand for electricity
Unused energy sources
Benefits of decentralised plants Satisfy own demands for electricty and process steam Take advantage of own energy sources like heat, biomass or waste Fuel from own industrial plant or the immediate vicinity avoid transport cost and logistic problems Independence of the national electricty grid
As a matter of fact the interest in such decentral power plants is increasing.
Decentralised plants

Christoph Frey
Products & Markets
Easy integration in the plant and the process
Operation with ordinary steam parameters / minimised peripheral equipment necessary
Pre-tested and ready-for-use for short erection and commissioning time
Low investment costs
High reliability
Simple operation which results in low personnel costs
Low operating costs
Design considers future duty changes Low revamp costs
Siemens pre-designed turbines in order to satisfy these criteria.

SST-110 (TWIN) example
Eccleshall Biomass Farming for energy is a proposal for a 2 megawatt power plant for the generation of electricity fuelled by energy crops. This is enough to run 2000 average households.
The main fuel, miscanthus (pictured) will be grown locally offering diversification opportunities and long term fuel supply contracts for up to 60 farms. A local Growers Group has already been established to co-ordinate fuel supply.Miscanthus is a non-invasive, sterile, perennial grass grown and harvested on local farms within a 25 mile radius of the plant.
The Biomass Power Plant is designed to ensure there will be no additional noise nuisance above existing background noise during 24 hour operation.
Emissions have been voluntarily set to a higher standard than the regulatory requirements for air quality. There will be no visible steam pump or odour emitted from the stack and performance will be monitored by Stafford Borough Council.
The plant saves 1 tonne per hour of CO2 which would be emitted generating electricity from fossil fuel.
