Claim:
1. A computer implemented method for controlling energy supply, the method comprising: identifying a first amount of energy to be used by at least one energy consuming device; identifying a second amount of energy stored in an energy storage; identifying an operation time period for operating the at least one energy consuming device; if the first amount of energy is greater than the second amount of energy, calculating a third amount of energy to request energy supply from an energy supplier to the energy storage based on the first amount of energy and the second amount of energy; if the first amount of energy is greater than the second amount of energy in the operation time period, searching for a time period which an energy cost is lower than in the operation time period, based on time-specific energy costs; and transmitting an energy supply request message to the energy supplier, wherein the energy supply request message comprises information related to the third amount of energy and the partial time period included in the searched time period.
