Saudi Arabian Grid Code May 2024

Grid Planning Studies 3.3.6.1 The TSP shall conduct Grid planning studies periodically or on as required basis to ensure the economic, safe, reliable, and stable functioning of the Transmission System, specifically for the following: (i) preparation of the Transmission forecast statement for next five years; (ii) preparation of Transmission development plans; (iii) evaluation of Grid reinforcement/extension projects; (iv) evaluation of any proposed User Development submitted to the TSP in accordance with an application for a new, or modification of an existing, Connection; (v) to assess the impact on the Transmission System or on any User System of any Demand Forecast or any proposed addition or change of Equipment or facilities in the Transmission System or the User System and to identify remedial measures to eliminate the deficiencies in the Transmission System or the User System; (vi) to assess the behavior of the Transmission System during normal and contingency conditions; (vii) to assess the System behavior during the electromechanical or electromagnetic transients induced by disturbances or switching operations; and Chapter 3 - Planning Code The Saudi Arabian Grid Code Updated Version: May 2024 (viii) any other planning assessment that may be required in the future to ensure adequate Transmission Capacity. 3.3.6.2 The Grid planning studies may include studies (as the situation or case may demand) such as load flow studies, short-circuit studies, transient Stability studies, steady state Stability studies, voltage Stability studies, electromagnetic transient studies, and Reliability studies, etc. 3.3.6.3 For Inverter-Based Resource facilities, the SCR at its Connection Point should be > 3.0. If the SCR is < 3.0, the User shall conduct a detailed electromagnetic transient study to evaluate the PPM or BESS connection and verify its compliance and its stable operation. Chapter 3 - Planning Code The Saudi Arabian Grid Code Updated Version: May 2024 APPENDIX A3.1: Standard Planning Data A3.1.1 Historical Energy and Demand A3.1.1.1 Each User directly connected to the TSP System shall provide to the TSP its actual monthly Energy and Demand consumption at each Connection Point for the immediate past year. A3.1.1.2 The User shall also provide the TSP with actual hourly load profiles for a TSP-specified weekday, weekend, and holiday for each season of the year. A3.1.2 Energy and Demand Forecast A3.1.2.1 The User shall provide to the TSP its Energy and Demand Forecasts at each Connection Point for the current year and the five (5) succeeding years. Where the User System is connected to the Grid at more than one Connection Points, the Demand Data to be provided by the User shall also include the Coincident Peak Active Power Demand. A3.1.2.2 The Forecast Data for the first year shall include monthly Energy and Demand Forecasts, while for the remaining years shall include only the annual Energy and Demand forecasts. A3.1.2.3 The User shall also provide to the TSP forecast hourly load profiles for a TSP-specified weekday, weekend, and holiday for each season of the year. A3.1.2.4 The User shall provide the net values of Energy and Demand Forecast for its System at each Connection Point after any deductions to reflect the output of any Embedded/Captive Generating Units/Station. Such deductions shall be stated separately in the Forecast Data. A3.1.2.5 Generators shall submit to the TSP their expected Demand to be served by each Generating Unit/Station. Forecast Data for Embedded/Captive Generating Units/Stations shall be submitted through the Distribution Entities, if applicable. A3.1.2.6 In order to avoid duplication of Forecast Data, each User shall indicate the Energy and Demand requirements that it shall meet under a contract. Where the User shall meet only a portion of the Energy and Demand requirements, it shall indicate in the Fo
