E.ON, one of the main natural gas suppliers in Romania, has provided detailed explanations for its millions of customers across the country on how their gas bill is calculated. Although the meter measures gas in cubic meters, the final cost is expressed in kilowatt-hours (kWh), making it easier to compare prices between different energy sources.
E.ON reports that since Romania aligned with European standards in July 2008, the kWh billing system has become mandatory for all participants in the natural gas market. According to what was presented by E.ON representatives, the conversion from cubic meters to kWh is based on the PCS coefficient – Higher Calorific Value. This indicator measures the total amount of heat released by the complete combustion of a cubic meter of gas, its values usually varying between 9.7 and 11.5 kWh/mc, depending on the chemical composition of the gas.
To ensure the accuracy of the conversion, the PCS values are determined daily in the metrology laboratories of TRANSGAZ, depending on the gas entry area into the national network. The averaged data are then transmitted to the suppliers, and E.ON integrates this information into the customers' bill. Within the bill, consumers can consult the "Meter data" table, where the applied PCS value is displayed, thus contributing to better transparency of energy consumption.

This billing method brings multiple advantages. By expressing consumption in kWh, an easy comparison is made with other types of energy, such as electricity or solid fuels, all of which are evaluated in the same unit of measurement. The system also allows monitoring of both the quantity and quality of the gas supplied. In the event of problems such as a drop in pressure or a different colored flame, consumers can promptly report these discrepancies to the supplier, who undertakes to intervene quickly.
E.ON remains committed to innovation and transparency in the services offered to its customers. The implementation of the kWh conversion system not only improves the clarity of billing, but also helps to accurately assess the costs associated with different heating solutions. This measure contributes to increasing customer confidence in natural gas services, ensuring that each bill reflects the real energy consumption, calculated based on daily verified values.
In conclusion, the explanations provided by E.ON highlight the importance of the conversion from cubic meters to kilowatt-hours. This process, based on the PCS coefficient, represents an essential step in modernizing the billing system and ensuring a high level of transparency for all natural gas consumers in Romania.
