CoP3 defines the BSC's minimum Metering System requirements for measuring and recording electricity transfers at Defined Metering Points where the rated circuit capacity does not exceed 10MVA.

This Code of Practice Four (CoP4) relates to the requirements for the Calibration, sample Calibration, Commissioning of Metering Equipment and the maintaining of associated records with respect to the above for Settlement purposes. It defines the minimum requirements that participants must meet.

This Code of Practice states the practices that shall be employed, and the facilities that shall be provided for the measurement and recording of the quantities required for Settlement purposes. This Code of Practice specifically applies to the Metering Equipment to be installed on each circuit where the Maximum Demand of the electricity being transferred does not exceed 1MW.

This Code of Practice states the practices that shall be employed, and the facilities that shall be provided for the measurement and recording of the quantities required for Settlement purposes. This Code of Practice specifically applies to Direct Connected Metering Equipment to be installed for the metering of energy imports via low voltage circuits fused at 100 AMPS or less per phase.

4.20

This Code of Practice states the practices that shall be employed, and the facilities that shall be provided for the measurement, recording and collection of the quantities required for Settlement purposes. This Code of Practice specifically applies to Metering and Data Collection Systems (MDCS) to be installed for the metering of energy imports via low voltage circuits fused at 100 AMPS or less per phase.

3.10

This Code of Practice states the practices that shall be employed and the facilities that shall be provided for the measurement and recording of the quantities required for Settlement purposes. This Code of Practice specifically applies to directly connected and transformer operated Metering Equipment to be installed for the metering of import active energy via low voltage circuits for non-half hourly settlement purposes.

This Code of Practice only applies to whole current and current transformer operated Metering Equipment for Import and Export Active Energy measured in kWh. No provision is made for the measurement of Reactive or Apparent Energy or any Maximum Demand.

This Code of Practice defines the minimum requirements for the metering of energy via low voltage circuits for Settlement purposes. This Code of Practice specifically applies to metering of energy via low voltage circuits for Settlement purposes. Metering Equipment compliant with this Code of Practice can be traded either Half Hourly where the Metering Systems are not 100kW Metering Systems (Measurement Class E, F or G) or Non-Half Hourly.
