Wnet = 15,000 kW and the exergetic efficiency is which is very high compared to any alternative power conversion cycle for similar heating fluid conditions. Operating conditions of the above New Zealand resource are as follows: Steam inlet temperature ('C) : 187 Steam flow rate (t/h) : 476.46 Brine inlet temperature ('C) : 187 Brine flow rate (t/h) : 1392.6 Geothermal fluid outlet temperature ('C) : 85 Plant net power (MW) : 90 Dead state temperature ('C) : 14 Use of a back pressure steam turbine Another approach for the higher enthalpy two-phase heat source is the use of a back pressure steam turbine which generates extra power from excess steam not required for the vaporizer of the Organic Rankine Cycle. Part of the preheating of the organic fluid is now done with low pressure steam exiting the back pressure steam turbine (Figure 10). Figure 10 The gap between the steam and the preheating line of the organic fluid could be filled even more efficiently by a multi-stage (two or more) back pressure steam turbine, with extraction of steam between the stages, but the decision on the number of stages is based on the consideration of the trade off in the process optimization between higher efficiency and the complication (and cost) of the system. A system based on the above cycle is now operating in the 20 MW Amatitlan geothermal power plant in Guatemala. (Figure 11). Figure 11 Figure 12 Geothermal Combined Cycle For high enthalpy fluids with very high steam content a solution is the geothermal combined cycle configuration where the steam flows through the back pressure turbine to the vaporizer, while the separated brine is used for preheating or in a separated Organic Rankine Cycle (Figure 13). Figure 13 This configuration is used in the 30 MW Puna plant in Hawaii (Figure 14), as well as in the following plants: 125 MW Upper Mahiao geothermal power plant in the Philippines (Fugure 15), 100 MW Mokai 1 and II geothermal power plants in New Zealand.
