The temperature of the geothermal source temperature should be higher than 150°C excluding the binary cycles which can operate at a geothermal source temperature of 95°C.

so theres binary cycle thingies that take lower temperature heat..

maybe can top this up a little?

The excess heat temperature ranges from 15 to 45 °C..
