Currently, electricity meters are procured, installed and maintained by SP PowerGrid Ltd (“SPPG”) for and on behalf of SP Power Assets ("SPPA"). SP Services Ltd (“SPS”) reads electricity meters and bills consumers buying electricity from SPS and provides the consumption data to electricity retailers and the market operator.

There are two types of electricity meters. Cumulative meters, which are manually read by SPS’ meter readers on a bi-monthly basis, and Advanced Metering Infrastructure (“AMI”) meters, which are remotely read using SPPA’s AMI system based on Wireless Smart Utility Network (“Wi-SUN”) technology.

To support the Government’s push for a singular network standard in Singapore for IoT sensors, Energy Market Authority (EMA) is working with other agencies to explore the feasibility of using NB-IoT network as the communication network for electricity AMI meters.
