摘要

PPROBLEM TO BE SOLVED: To suppress a power demand at a power demand peak time, by quickly and automatically notifying arrival at the power demand peak time and an electrical energy consumption suppressing request to a customer so as to voluntarily suppress power consumption on the customer side. PSOLUTION: An automatic meter-reading system 10 is constituted of: an automatic meter-reading apparatus 100, including a consumption management means 110 for registering meter-reading value data in a consumption history database 125; a consumption calculation means 111 for calculating total electrical energy consumption of each customer in each fixed time; a peak monitoring means 112 for determining whether the total electric energy consumption reaches electric energy with the predetermined vertical width of power suppliable amount, for each fixed time, and a peak notification means 113 for sending a peak time notification to each smart meter, when the total electric energy consumption reaches the electrical energy with the predetermined vertical width of the power suppliable amount; and a smart meter 200, including a meter-reading value data transfer means 210 for generating the measured electrical energy consumption as a meter-reading value data and sending the meter-reading value data to the automatic meter-reading apparatus, and a notice receiving time means 211 for receiving the peak time notification from the automatic meter-reading apparatus and outputting the received peak time notification.
