ELECTRICAL POWER CHARGE UNIT PRICE CHANGE SYSTEM BY MEASUREMENT OF QUANTITY DEMANDED

摘要

PROBLEM TO BE SOLVED: To restrain generation of facility investment and energy production more than necessary, in consideration of peak power demand by leveling the power demand. SOLUTION: This system is provided with a power user terminal, connected to a power supplier server via a network, a power demand measuring means for estimating the power demand based on the utility time of an apparatus on power user side, and a power charge unit price changing means which has an electrical charge unit price function with the power demand as a variable and calculates the power charge unit price, based on the measured power demand, and outputs the electrical charge unit price to the power user terminal.
