Electricity bill validation is a “bottom-up” approach using the interval data directly from the meter to replicate each NMI’s monthly bill. We compare this to the retailer bill and investigate/rectify any variances directly to the retailer (on our client’s behalf). Each month a report is produced which includes any findings, but also trending energy usage or issues. Any variances found are investigated by us – such as unusual consumption, incorrect demand settings and power factor.
