Estimation Methodology:
If actual data for the last months of the reporting period isn’t available at the time of reporting, follow this approach:
Step-by-Step Estimation Rule:
Use actual monthly data for all available months in the reporting year.
Calculate the monthly average from the available months.
Multiply that average by the number of missing months to estimate those periods.
Add the estimated consumption to the actual year-to-date total.
If your invoice shows data in cubic meters (Nm³). You need to convert this into kilowatt-hours (kWh) for consistent reporting. If your invoice shows Nm³, than use the below formula:
kWh = Nm³ × 𝑥
Note that the value of 𝑥 is dependent on which region you operate in:
EU-based operations: Use 10.55
UK-based operations: Use 10.89
US-based operations (metric): Use 9.81
US-based operations (imperial): Convert from Therms
(1 Therm = 29.3 kWh)Serbia-based operations: Use 9.50
India-based operations: Use 10.56
