Utility Invoice Auditing

Energy bills are intricate. Utility companies must follow hundreds of pages of billings, tariffs, and evolving rate structures to calculate an invoice. Implementation errors are common even though these rates are regulated by relevant Public Service Commissions. Furthermore, electing energy supply from a third-party supplier increases the chances of billing errors. As a result, supplier and utility invoices in often contain substantial errors worthy of billing refunds. NuEnergen are experts in modelling utility tariffs and third-party supply rates – let us help ensure accurate billing.
