There are almost two million electricity customers in the household category in Croatia. Reading the meter monthly, or once in two months would add additional cost to the distribution system operator, which would increase the overall price of electricity. To avoid that, advance payment is applied, i.e. each customer’s monthly consumption is estimated in the period before next calculation, which is defined by General requirements for electricity supply as the standard service for all customers.

Monthly monetary obligation, i.e. “advance payment” represents an invoice for agreed electricity consumed in a calculation period, with a due date on 15th of the next month.

In case of ownership changes, in a 30-day period from the change you should contact HEP ODS in order to change the port (the metering point) information and notify RWE Energija.
