Invoice reconciliation and unit cost control
In industrial plants, distribution and supply invoices arrive separately; PTF, YEKDEM, distribution fees and reactive items feed directly into production cost. Invoice reconciliation cross-checks the OSOS period total against the kWh line; unit price deviations show in which item they arise. In factories with eligible consumer status, the hourly profile feeds the energy purchasing strategy. Our electricity invoice tracking page explains the reconciliation process step by step. Energy managers and finance work from the same verification report to speed up dispute processes.
Submeter and process-level consumption measurement links invoices to production line costs. It becomes visible which shift or line has a rising unit energy cost. The industrial energy measurement guide offers a practical framework for OSOS and submeter infrastructure.
EİVER, energy audits and ISO 50001
Industrial facilities covered by the Energy Efficiency Law must commission energy audits at set intervals and report improvement actions. Continuous OSOS and submeter data provide audit input; the consumption inventory stays current. The ISO 50001 energy management system requires the same data flow for measurement plans, energy performance indicators and management reviews. The EİVER 2026 obligations guide summarises the legal framework; our ISO 50001 guide walks through certification.
TOE (tonne of oil equivalent) reporting expresses corporate energy consumption in a single language. Our TOE calculator compares different energy carriers and feeds audit and carbon reporting.
The ENOPTIMAL industrial solution
The ENOPTIMAL Consumption Management System combines OSOS integration, invoice reconciliation, reactive alerts and a multi-subscription portfolio in a single operations centre. The factory energy manager tracks shift-based consumption, peak load risk and invoice verification status in the same list. When production planning and energy cost are aligned, unit product cost comes under control.
