To satisfy both the metrological and accuracy required from the buying and selling of electricity, the invention provides a system that comprehensively provides real-time billing of electricity (and other commodities) to both the customer and the retailer. This is done through the combination of a metering unit, a communications unit, a WAN and an algorithm to continually calculate the billing figure in 'real-time'. The combination of these elements is set out in the attached drawing. The algorithm to create the bill is unique to this invention. The way this system has been created is unique to this invention. The invention can also sub-meter individual electrical circuits. Using the abovementioned 'system, individual circuits can show what amount they will cost the 'end-user'. The algorithm that is used to calculate the 'live bill', is unique to this invention. It uses the 'tariff to calculate the rate but its 'apportionment' mechanics is unique and makes the apportionment accurate, and accounts for 'load factor' 'kva' 'line loss' and a range of other factors that are used to calculate the 'overall bill. |
