Saudi Arabian Grid Code May 2024

In order to properly account for the flow of electricity through the Transmission System, it is imperative that suitable and accurate metering and recording facilities are provided at all Connection Points on the Grid. This chapter, therefore, deals with metering and recording requirements for Participants and clarifies on their obligations relating to such installations. It also sets the minimum technical, design and operational criteria to be complied with by Users relating to metering and data collection Equipment and installations. 7.1.2 The provisions of this chapter are specifically applicable to issues relating to the following: (i) supply, installation, and maintenance of Metering Equipment (Main as well as Check) and their testing and calibration; (ii) collection, storage, and communication of metering data; and (iii) competencies and standards of performance of Participants relating to metering. Objective The objective is to set out the responsibilities of the Participants relating to measuring and recording of Active and Reactive Power flows and Energy imports into or exports out of the Grid and also to specify the terms and conditions that will govern the metering and recording Equipment and systems employed for the above purpose. Metering Responsibility 7.3.1 The TSP shall be responsible for managing and collecting metering information and shall ensure that all points identified as Metering Points in the relevant Connection Agreement have proper metering facilities. 7.3.2 The User shall be responsible to provide Meters and the associated Equipment and facilities at the Connection Point and offer these for installing and sealing by the TSP along with proofs of certification in respect of Meters and the CTs and VTs by an accredited laboratory as set out in (7.3.4) below. Chapter 7 - Metering Code The Saudi Arabian Grid Code Updated Version: May 2024 7.3.3 The User shall also be responsible to demonstrate that its Metering Equipment meets all the technical requirements and standards set forth in this chapter. 7.3.4 Prior to making them available to the TSP for installing and sealing, the Users shall submit the Meters for certification to an independent laboratory accredited for such purposes by the Saudi Accreditation Center. 7.3.5 The TSP shall ensure that installation, Commissioning, maintenance, auditing, and testing of Metering Equipment and allied systems are done in accordance with the standards as specified in the relevant Connection Agreement. 7.3.6 Notwithstanding (7.3.2 to 7.3.4) above, once installed, all Main Meters shall be owned and operated by the TSP. 7.3.7 The User shall also provide to the TSP all the information that the TSP will reasonably require to perform its metering duties properly. Metering Equipment The Metering Equipment at the Connection Point shall consist of: (i) Meters; (ii) Instrument Transformers; (iii) Lightning Protection; and (iv) All other interconnecting electric/telecommunication cables, wires, and associated devices, etc. Metering Point 7.5.1 The Metering Point shall be at the Connection Point on the Transmission System, as specified in the relevant Connection Agreement. 7.5.2 The Actual Metering Point may differ from the Connection Point, if agreed by the TSP and the User. The accuracy requirements of the Metering Code then shall apply to the Actual Metering Point. 7.5.3 Where the Actual Metering Point and the Connection Point do not coincide, then, where necessary, compensation for Power transformer and/or line losses shall be provided. The compensation may be applied locally within the Metering Equipment or remotely. In both cases, however, compensation factors and the justification for them must be recorded.
