Provided is a thermal energy network system including: a first thermal station that stores first thermal energy using a first heat source and supplies the first thermal energy to a first demand source used for residence or commerce; and a second thermal station that stores second thermal energy using a second heat source and supplies the second thermal energy to a second demand source used for industry, wherein the first thermal station and the second thermal station manage a base load of a thermal energy network, and the first thermal energy and the second thermal energy are transferred between the first thermal station and the second thermal station as needed. Thus, each of the first thermal station and the second thermal station can supply necessary thermal energy to each of the first demand source and the second demand source, and bidirectional thermal energy movement between the first thermal station and the second thermal station can be performed so that thermal energy availability can be improved.
