Electricity metering is a complex process that requires the collaboration of various entities to ensure accurate measurement and efficient energy management. Understanding the roles and responsibilities of these entities is crucial for maintaining compliance and facilitating the smooth functioning of the electricity market. In this article, we will explore in detail the key roles in electricity metering, including Financially Responsible Market Participants (FRMPs), Metering Coordinators (MCs), Metering Providers (MPs), and Metering Data Providers (MDPs), as outlined in Chapter 7 of the National Electricity Rules (NER), Version 203.

Financially Responsible Market Participants (FRMPs):
Financially Responsible Market Participants have the financial responsibility for a connection point in the electricity market. Their obligations include establishing metering installations and ensuring compliance with regulatory requirements. According to Clause 7.2.1(a) of the NER, FRMPs must appoint a Metering Coordinator and ensure that the connection point has a registered metering installation. “Except as otherwise specified… the financially responsible Market Participant must ensure that… a Metering Coordinator is appointed… and the connection point has a metering installation registered with AEMO.” (NER, Version 203, Clause 7.2.1(a))

Metering Coordinators (MCs):
Metering Coordinators play a pivotal role in the provision, installation, maintenance, and security of metering installations. They are responsible for collecting metering data, processing it, and delivering it to the metering database and other relevant parties. MCs also manage access to and ensure the security of the metering installation. The appointment of a Metering Coordinator is essential to comply with the regulatory requirements.

According to the NER, “For the term of its appointment… the Metering Coordinator is the person responsible for the provision, installation, and maintenance of a metering installation… collection of metering data… and managing access to and the security of the metering installation.” (NER, Version 203, Clause 7.3.1(a))

Metering Providers (MPs):
Metering Providers are appointed by Metering Coordinators to handle the provision, installation, maintenance, and testing of metering installations. They play a critical role in ensuring that metering installations comply with regulatory requirements and perform accurate measurements. MPs are responsible for maintaining and servicing the metering equipment and ensuring its proper functioning.

As per the NER, “The Metering Coordinator… must appoint a Metering Provider… for the provision, installation, and maintenance of the metering installation…” (NER, Version 203, Clause 7.3.2(a))

Metering Data Providers (MDPs):
Metering Data Providers are responsible for providing metering data services. They collect, process, and retain metering data in the metering data services database and deliver it to the metering database and other relevant parties. MDPs play a crucial role in ensuring the accuracy and availability of metering data for market participants, regulators, and consumers.

The NER states, “The Metering Coordinator… must appoint a Metering Data Provider to provide metering data services…” (NER, Version 203, Clause 7.3.2(d))


Electricity metering relies on the coordinated efforts of Financially Responsible Market Participants, Metering Coordinators, Metering Providers, and Metering Data Providers. Each of these roles has specific functions and responsibilities that contribute to accurate metering, data collection, and maintenance of metering installations. By understanding the roles and their interplay, stakeholders can actively participate in a well-functioning electricity market that promotes transparency, accountability, and efficient energy management.
