• The percentage comparison of total AMI amount consumption and total amount trend

  The percentage comparison of total AMI amount consumption of current year and last year will be shown on the indicator dashboard. The monthly power consumption trend for the two years next to the dashboard to directly compare whether the total consumption has increased or decreased.

Figure 7 The percentage comparison of total AMI amount consumption and total amount trend

• Comparison of average total consumption in the same area/industry

The users could check their own total consumption and the average power consumption in the same area or industry. And it would provide different contents via different scenarios to guide users to change their energy consumption behaviors.

Figure 8 Comparison of average total consumption in the same area/industry

• Setting Daily Power Limit

  Provide users with the ability to set the upper limit of daily electricity consumption. When the electricity consumption exceeds the self-set degree, the user will be notified by email.

Figure 9 Self-defined amount consumption upper limit and abnormality notification

• Carbon Emission

  According to whether the amount consumption exceeds the “ average total consumption in the same area “ or “ Self-defined amount consumption upper limit “, the icons of carbon emission and trees are provided to strengthen the connection between amount consumption and energy saving.
