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 (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. 

Cumulative Electricity Meter	Advanced Electricity Meter

Not applicable to households that continue to buy electricity at the regulated tariff rate.

Advanced electricity meters allow households to have ready access to their electricity consumption information at half-hourly intervals via the SP 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 1.58 million household accounts in Singapore can expect to have advanced electricity meters installed at their premises by 2026. 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. 

Yes, households that wish to have their advanced electricity meters installed ahead of their scheduled meter replacement date will need to pay a one-time meter installation fee (inclusive of prevailing GST). Details are available under Market Support Service Charges.

Cumulative meters that have reached the end of their lifespan would need to be replaced with advanced electricity meters.

Advanced electricity meter costs are recovered as part of providing grid infrastructure services, which are part of electricity rates charged to households.

With access to their electricity consumption via the SP App, households can take steps to manage their usage more efficiently and enjoy savings as a result.

SP Group's installation of advanced electricity meters does not affect households’ ability to buy electricity from a retailer of their choice.

There are currently no plans to replace the existing gas and water cumulative meters with advanced meters.
