Meter reader takes reading on the “Next Reading Date” indicated on your bill every month. If meter reader is unable to take meter reading, CEM will estimate the electricity consumption of the month based on the average consumption of the past 12 months and issue an estimated bill in accordance with number 3 of Article 19 of Decree-law No. 43/91/M.
The front of the bill and envelope are in blue color, and “Estimated Bill” is printed on the bill’s header and the front of the envelop. In addition, an “E” is indicated next to the meter reading on back of the bill for identification.
The electricity amount during estimated period will be automatically recalculated after actual reading is taken. If you would like to have estimated bill adjusted, you can schedule a meter reading appointment with us or submit self-reading before the “Payment Due Date”. In addition, CEM only accepts estimated reading/self-reading for 3 consecutive months. Power supply may be suspended if actual reading cannot be taken for more than 3 consecutive months.
After actual reading has been taken, CEM will first refund all the collected estimated amount and recalculate the amount during the estimation period and current month based on the two latest actual readings and total consumption days, including demand, consumption, tariff clause adjustment and government tax. Lastly, all the government subsidies (if applicable) of the affected month(s) and previous payment(s) will be deducted to calculate the adjusted bill amount.
As shown in the example below, the bill has been estimated for the past two months and adjusted after the actual reading is taken this month.
No, you will not be double charged. CEM will first refund all the previous estimated amount and recalculate the amount based on the actual electricity consumption during the estimation period and current month. All electricity subsidies will also be adjusted accordingly.
