Abstract
An energy supply system operates to supply heat energies, such as cooling water, steam, heating water, etc. to a community, and the system has a function for predicting a future energy demand of the community and to correct it. In a system having an energy plant to store energy and an energy supply pipeline network for connecting the energy plant to the community, the system includes an energy demand plan making section for predicting an energy demand of the community on the basis of past cases of energy supply and for formulating an energy demand plan with respect to time, and an energy demand variation detecting section for determining a variation of the energy demand from the energy demand plan by using a personnel flow measured value measured by personnel flow measuring apparatuses provided at paths to or positions of the community as a parameter. The variation of the future energy demand of the community is predicted and energy which accomodates the determined variation can be prepared.
