PTF, YEKDEM, distribution fees and reactive items should be monitored separately.
On invoices under eligible consumer and SKTT status, the active energy charge consists largely of PTF (market clearing price) and YEKDEM components. Multiplying the hourly consumption profile in the billing period by these prices determines the total amount. On the distribution company invoice, distribution fees, system usage fees and meter services appear as separate lines. Our SKTT and eligible consumer guide explains the impact of these items at contract renewal time.
Inductive and capacitive reactive energy, contracted power overruns and demand (peak demand) items are the lines where operational errors surface on the invoice. Without OSOS data, the reactive ratio can only be checked after the invoice is issued. Our reactive energy and reactive charge guide details compensation and penalty thresholds; invoice tracking should verify these items together with the OSOS profile.
Excel-based tracking may suffice for a single subscription; as the portfolio grows, software scales.
Category-based comparison — no competitor names; operational differences are summarised.
| Criterion | Manual process | With software (ENOPTIMAL) |
|---|---|---|
| Data source | PDF/Excel invoices, separate OSOS files | Invoice + OSOS + subscriber in one data model |
| Reconciliation time | Hours per subscription; delays at scale | Automatic matching; instant deviation list |
| Unit price checks | Manual maths; tariff table tracked separately | Line-item verification and difference report |
| Reactive / demand | Noticed after the invoice is issued | Advance warning from the OSOS profile |
| Reporting | Scattered files; hard to audit | Central verification report and archive |
A unit price deviation means the cost per kWh on the invoice differs from the expected value calculated with OSOS period consumption and the applicable tariff table. Deviations can hide in the total amount alone: consumption may look low while the unit price stays high. For accurate reconciliation, active energy, distribution, reactive and power items are checked separately. In bilateral or indexed contracts, the invoice line is cross-checked against the PTF+YEKDEM period average. ENOPTIMAL reports these checks automatically per subscription; the energy purchasing team sees, as a list, which invoice deviates in which item.
Distribution company and supplier invoices may have different period alignment; during reconciliation, the overlap between the invoice cut-off date and the OSOS data range must be verified. Events such as tariff group changes, contracted power revisions or temporary outages affect the unit price. Software-driven tracking links these events to the subscriber history; a manual process needs recalculation every period and the error risk grows.
In OSBs, industrial groups or multi-branch businesses, every facility has its own subscription number, tariff group and contracted power. When invoice tracking is split across Excel files, keeping it current becomes difficult; consistency is lost in audits and EİVER reports. When subscriber, meter, location and responsible unit are matched in a central inventory, invoice verification scales. Our OSOS consumption monitoring page explains how hourly data feeds invoice reconciliation. The industrial energy measurement guide offers a practical framework for submeter and OSOS infrastructure.
The ENOPTIMAL Consumption Management System combines invoice upload, OSOS integration, unit price verification and reactive alerts in one operations centre. Across a multi-subscription portfolio, verification status, deviation amount and period comparison are tracked in a single list. Used together with our contracted power guide for contracted power and peak load risk, invoice items align with operational decisions.
Industrial plants with high annual electricity consumption, organised industrial zones, retail chains and logistics networks, and public building portfolios benefit directly from invoice tracking. For subscribers with eligible consumer status, PTF and YEKDEM fluctuations affect the monthly budget; for those remaining on the distribution side, distribution fees, reactive and power overrun items should be monitored. When energy managers, finance and purchasing teams can look at the same verification report, dispute processes accelerate. Our article on the importance of energy management and tracking summarises the operational benefits of digital monitoring.

Frequently asked questions
Frequently asked questions about electricity invoice tracking, reconciliation and unit price checks.
It means verifying distribution and supply invoice items (consumption, unit price, PTF, YEKDEM, distribution fee, reactive) against system data and monitoring period deviations. Combined with OSOS hourly data and subscriber info, invoice errors and unit-price gaps are caught early.
Excel can work for a single low-volume subscriber; with many sites, free consumers or dozens of monthly invoices, manual work slows and error risk rises. Software auto-matches OSOS totals, tariff items and unit prices and reports mismatches per subscriber.
Invoice kWh and totals are compared with OSOS period totals and the active tariff table. PTF+YEKDEM, distribution and reactive items must be checked separately. Deviations report which item and period; bilateral contract vs tariff error is separated.
For free consumers and SKTT, energy cost largely depends on PTF and YEKDEM. Hourly consumption times market prices drive the total. A YEKDEM or PTF gap can move a large share of the monthly bill; reconciliation tracks these items separately.
Invoice, OSOS and contract data should live in a central inventory per subscriber and site. ENOPTIMAL lists uploads, verification status, unit-price gaps and reactive alerts for multi-subscriber portfolios. OIZs, industrial groups and multi-branch firms use one ops screen instead of scattered Excel.
The reactive line is compared with inductive/capacitive ratios from OSOS. Limit breach or bad compensation adds cost on the bill. Reactive monitoring is part of reconciliation; alerts fire before penalties.
