EMA (Electricity Meter Analyzer) is a program that helps you determine the accuracy of power bills received from your electricity retailer, it does this by analysing each half hour interval by time of day and the power type (peak, off peak, shoulder and controlled load) then applying the rate for each of the types to come up with what it believes is a total cost for the power used. Before EMA can do this, you need to obtain the NEM12data to import from your retailer which they must provide by law when asked by you. It is essential that it is made clear to them that the file they provide is the same as that received by the retailer via their electricity distributor or network provider and you must set options that EMA uses to customize data entry requirements based on your tariff power types. EMA will only convert data to it's standard format using the NEM12 data file, the format of this file is governed by a national standard which ALL electricity distributors must adhere to. If the file you receive is not to this standard, import will fail and you will not be able to produce a bill comparison. As well as the cost for the power used, EMA will also calculate the meter charge, any off peak concession, government rebates and other discounts or charges for the read cycle. EMA also shows usage, costing and weather data along with solar generation in graphs making it easy to see your daily usage in half hour intervals, you can also compare days for the same period for the previous year(s).
