I am interested in some remarks regarding power generation from low-temperature resources, yet no up-to-date papers are available. Had you any information - I would be grateful for sharing.
Chena Hot Springs Resort uses two 200kW Organic Rankine Cycle (ORC) geothermal energy power plants to generate energy, the first in Alaska. The resort moved the diesel generators used in the past to a backup role since July 2006, and it is successful in reducing the cost from 30 cents/kWh to 5 cents/kWh. The resort owners have plans to increase the powerplant's work output from 200 kW to 1MW. An increase to 730 kilowatts was accomplished.
Chena appears to be the lowest temperature geothermal generator, with the Rankine cycle operating at only about 75 C. It is small, but replaces its diesel generator in this remote community. Waste heat is also used for green houses.
