The Metering Code (MC)

The Metering Code (MC) is divided into three distinct parts, each addressing different aspects of metering within the power system. Here's a more detailed breakdown of each part:

1. General Conditions:

• This section outlines the fundamental rules and conditions that apply to the entire Metering Code.
• It provides the framework for the implementation and enforcement of the metering standards and procedures detailed in the subsequent parts.
• General Conditions ensure consistency and compliance across all metering activities governed by the Code.

2. Grid Metering Code (GMC)

• This part focuses on the requirements for metering at the Participant’s Connection Points on the Transmission or Distribution Network.
• It caters to the Commercial Metering System, which is essential for the accurate measurement and accounting of energy and power exchanges.
• The GMC covers two main scenarios:
  • (i) Energy and Power Entering or Exiting the Transmission Network: - This involves the metering of energy and power that either enter or exit the high-voltage transmission network. - Accurate metering at these points is crucial for grid management, energy trading, and regulatory compliance.
  • (ii)Energy and Power Entering or Exiting the Distribution Network at Participant’s Connection Point: - This involves metering at points where the distribution network interfaces with participants, such as large consumers or distributed generation units. - Ensures precise measurement of energy transactions between the distribution network and its connected participants.

3. Distribution Metering Code (DMC)

• This part specifies the technical and operational criteria for metering within the Distribution System.
• It includes detailed procedures that must be followed by the Distributor to provide reliable and accurate metering services to customers.
• The DMC covers the following key aspects:
  • Technical Requirements: Outlines the technical specifications for metering equipment and installations, ensuring they meet industry standards and regulatory requirements.
  • Operational Procedures: Details the processes and protocols for meter installation, maintenance, calibration, and data collection.
  • Customer Metering: Focuses on metering for customers of the Distribution System, ensuring that all customers, except participants, are accurately metered for energy and power consumption.
  • Energy and Power Interchange:
    • Covers the measurement of energy and power that enter or exit the Distribution Network at any Customer’s Connection Point, excluding participants.
    • Ensures fair and transparent billing and energy accounting for all customers.
