Abstract Combining geothermal and fossil fuel energy into the so called "hybrid" cycle is compared with a state of the art double flash geothermal power cycle using resources which vary from 312°F to 598°F. It is demonstrated that a hybrid plant can compete thermodymically with the combines output from both a fossil fired and a geothermal plant operating separately. Economic comparison of the hybrid and double flash cycles is outlined, and results are presented that indicate the performance of marginal hydrothermal resources may be improved enough to compete with existing power cycle on a cost basis.
