PROBLEM TO BE SOLVED: To provide an operation method for a steam system optimizing distribution of bleeding quantity of each turbine generator with a pressure necessary for apparatuses using the steam secured, and maximizing generation efficiency of a whole power generation system in steam generation facilities for power generation provided with a plurality of turbine generators. SOLUTION: In a steam supply and demand system comprising a plurality of bleeding-condensation type turbine generators generating electric power by using high pressure steam from a high pressure steam boiler, bleeding part of steam getting to a low pressure by the power generation, and using the remaining steam for further power generation, and steam pipe connecting the bleeding-condensation type turbine generators and a plurality of apparatuses using the low pressure steam, data of bleeding quantity from the bleeding-condensation type turbine generator, present use quantity and use quantity prediction value of each apparatus using steam are acquired, an optimal bleeding pressure value satisfying a necessary pressure value of each apparatus using steam is calculated by performing pipe network calculation of the steam pressure and flow rate based on the date, and the turbine generator is operated at the optimal bleeding pressure value.
