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 a methodology approved by the Energy Market Authority.

Advanced electricity meters allow electricity consumption to be measured at half-hourly intervals and you can track your consumption via the SP Utilities mobile 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.

Advanced electricity meters allow households to have ready access to their electricity consumption information at half-hourly intervals via the SP Utilities mobile app. Households can then monitor their consumption habits and take action to reduce their consumption and be more energy efficient.

Both cumulative and advanced electricity meters require about the same amount of power to operate.

The deployment of the advanced electricity meters will depend on a variety of factors including the age of existing meters, development plans in the area and meter deployment efficiency.

All 1.4 million household accounts in Singapore can expect to have advanced electricity meters installed at their premises by 2024. This timeline takes into account the time and effort required to schedule the meter replacement for every household and when existing meters reach their end of life.
