In the present paper authors presented the way to improve the effectiveness of operation of a geothermal power plant. The procedure is based on a replacement of a single loop cycle with a multi loop cycles as well as on combination of a power plant system with a heat distribution network which supplies thermal energy to recipients. As a result of that conversion the systems of geothermal heat and power plants have been developed. The fundamental objective in these systems is production of electricity. The remaining, unused part of energy, is directed to the central heating recipients. In the paper presented have been the benefits stemming from the replacement of geothermal power plant with a heat and power plant and replacement of a single loop cycle with a multi-loop cycle system. In particular sections of the paper presented also will be assumptions for the particular cycles, values of characteristic parameters of cycles, the calculation algorithm, results of calculations together with their graphical interpretation and final conclusions.
