1. A display apparatus which displays a usage status of power supplied from a grid, comprising:
- a display, anda controller configured to control the display to display a first image indicating a coordinate space expressed by a first coordinate axis and a second coordinate axis crossing each other, whereinthe first coordinate axis is a coordinate axis for specifying a magnitude of a first power amount supplied from the grid in a first period,the second coordinate axis is a coordinate axis for specifying a magnitude of a second power amount supplied from the grid in a second period different from the first period,the first power amount corresponds to a basic rate for receiving a power supply service,the second power amount corresponds to a metered rate for receiving the power supply service,the controller is further configured to display a second image with the first image, the second image indicating the first and second power amount at a current time in the said coordinate space, andwherein the controller controls power consumption of a load in accordance with the displayed usage status of power supplied from the grid.

Abstract
In the present invention, in a coordinate plane that receives an expression according to a first axis indicating a parameter that impacts a basic rate and a second axis indicating a parameter that impacts a metered power rate, a display unit (230) displays an image indicating coordinates indicating the use state of power received from a grid.
