Energy management system and energy management method

Abstract

To enable the time-shifting of cooling and heating demand in a manner that satisfies economic and operational requirements for businesses. [Solution] The system includes a communication unit 11 that communicates with a higher-level system that creates an energy plan for the region to which the target customer site belongs, a target setting unit 12 that sets a target value for creating adjustment capacity at the target customer site, a forecasting unit 13 that predicts the future electricity demand of the target customer site, a boundary condition setting unit 14 that sets boundary conditions for demand control from the load equipment specifications of the target customer site, an operation plan creation unit 15 that creates a demand control plan for the load equipment of the target customer site from the target value for adjustment capacity, the future electricity demand forecast, and the boundary conditions for demand control, and an input / output unit 16 that performs input and output with the target customer. The regional energy plan is created or modified by the higher-level system based on whether the demand control plan can be implemented.
