What is the difference between a cumulative and an advanced electricity meter?
Most residential premises today use cumulative meters to measure electricity consumption. Cumulative meters are read once every two months when SP Group sends a meter reader to your premises to record your electricity usage. On the month when your meter is not read, SP Group will estimate the month's consumption based on the methodology approved by EMA.
Advanced electricity meters allow electricity consumption to be measured at half-hourly intervals and you can track your consumption via the SP app. With these meters, you will also have the option* to be billed based on your actual consumption, instead of estimated consumption, on alternate months.
*Not applicable to households that continue to buy electricity at the regulated tariff rate.
