SST-040 looks a good candidate : 300kW from 1MW
http://www.energy.siemens.com/hq/en/power-generation/steam-turbines/sst-040.htm
The newly developed predesigned steam turbine SST-040 is a generator drive
specially designed for the 75-300 kW power range. This favorably priced turbine
features a simple, extremely compact design, short start-up times and a high
degree of operational reliability.
Application area of the SST-040:
* Waste-heat recovery e.g. behind gas engines and biogas engines
* Small CHP plants
* Decentralized solar facilities
Inlet pressure 2 up to 40 bar (a)
Inlet temperature dry saturated steam up to 400 °C
