In the context of the allelectric kitchen pilot project implemented by State Grid Hunan Power Co., Ltd., the architecture of the kitchen energy efficiency supervision platform is introduced. Relying on the all around data collected during the construction and operation of the project, the costs of the kitchens are analyzed and calculated, and the economics of electrified kitchen and traditional kitchen are compared. The environmental and social benefits brought by the implementation of the project are analyzed, and energy efficiency analysis is carried out. It’s concluded that electrified kitchen is superior to traditional kitchen in all aspects, indicating that all electric kitchen is a future development trend and can be gradually promoted.
