Here’s information about the types of meters and metering options, if you intend to buy electricity from a retailer.
There are two types of electricity meters:
- Most residential premises today use cumulative meters to measure electricity consumption. SP Group sends meter readers to your premises to record your electricity usage from cumulative meters.
- Cumulative meters are read once every two months. On the month where your meter is not read, SP Group will estimate the month’s consumption based on a methodology approved by the Energy Market Authority.
- Advanced meters, also known as smart meters or Advanced Metering Infrastructure (AMI) meters, allow electricity consumption to be measured at half-hourly intervals.
- Consumers with advanced meters can view and download their half-hourly electricity usage on the SP Utilities mobile app.
- There are two types of AMI meters – single-phase and three-phase. The type of meter required for your premises depends on your premises’ voltage intake level. Residential consumers typically require single-phase AMI meters.
To empower households to use electricity more efficiently, advanced meters will be installed across Singapore over the next five years. SP Group will notify you in advance via mail when your advanced meter is scheduled to be installed at your premises.
You may wish to contact SP Group at email@example.com
or 1800-233-8000 to find out which type of meter is installed at your premises.
If you are eligible to switch to a retailer, the following metering options are available:
Load Profile Metering Option
Retain your existing meter
while signing up for a time of use plan. Your meter will continue to be read
once every two months. A load profile will be used to estimate your half-hourly
consumption for billing purposes. Learn more about the load profile in the section
Advanced Metering Option
Install an advanced meter* and be billed on based on your actual consumption on a half-hourly basis. A meter installation fee of $40 (before GST) may apply. Consumers who are on an advanced metering option can also view and download their half-hourly electricity usage when they sign up for an e-Services account.
*If you have an advanced
meter installed prior to switching to a retailer, you can choose to be billed based
on i) your actual half-hourly consumption or ii) a load profile at no
additional cost. Please check with your retailer for more details.
Do I Need an Advanced Meter?
You can continue to retain your existing meter, or install an advanced meter when switching to a retailer. Please check with your retailer on the cost, if any, of installing an advanced meter.
As at end September 2019,
about 290,000 advanced meters have been deployed at households across
Singapore. The remaining 1.1 million households will have advanced meters
installed by 2024. Learn more about this initiative.
EMA has developed a load profile of the average household in Singapore. This load profile can be applied to the monthly electricity consumption of a household to derive your estimated half-hourly electricity consumption for billing purposes. EMA will periodically update the load profile to ensure that it remains reflective of the average household’s consumption.
Based on EMA’s study, households exhibit similar consumption patterns. As such, having a Load Profile is suitable for all households regardless of dwelling types. On the other hand, having a Load Profile is not feasible for businesses as they have different consumption patterns depending on the nature of business.
Here is a diagram showing the load profile of an average household.
Business consumers who wish to switch to a retailer will need to install an advanced meter (also known as a smart meter).
The advanced meter will allow you to measure your electricity consumption on a half-hourly basis. A meter installation fee of $40 (before GST) may apply.
