Saudi Arabian Grid Code May 2024

Introduction 4.2.1.1 This section deals with Demand forecasting for operational purposes, and lays down the procedures to be followed and data to be supplied by Users to the TSP to enable the TSP to forecast Demand on the Transmission System for the period ranging from five (5) years ahead down to real time operation. 4.2.1.2 This section also deals with the provision of data on Demand Control in the Operational Planning Phase, the Programming Phase, Control Phase, and the Post Control Phase. 4.2.1.3 The TSP shall be responsible for developing Demand Forecasts for the Operational Planning Phase after taking into account the Demand Forecasts supplied by Distribution Entities and Directly-connected Customers. Chapter 4 - Operating Code The Saudi Arabian Grid Code Updated Version: May 2024 4.2.1.4 In the Programming Phase and Control Phase, the TSP shall develop its own Demand Forecasts after taking into account, information to be furnished by Distribution Entities, Directly-connected Customers, and Generators. 4.2.2 Definitions 4.2.2.1 In this section, a reference to Year 0 shall mean the current calendar year, Year 1 shall mean the next calendar year, Year 2 shall mean the calendar year after Year 1, and so forth. 4.2.2.2 A reference to data being supplied on an hourly basis shall refer to it being supplied for each period of 60 minutes ending on the hour. 4.2.2.3 Reactive Power Demand shall include the series reactive losses of the User System bus but exclude any network susceptance and any reactive compensation on that System. The TSP shall obtain the lumped network susceptance and details of the reactive compensation from the data supplied by the User as provided in Chapter 3: Planning Code. 4.2.3 Objectives The objectives of this section are to specify: (i) the requirements for Grid Users to provide Demand and Generating Plant output data to the TSP to enable it to plan and maintain sufficient level of Generation Capacity and Operating Margin in the System to meet Demand; and (ii) the factors which the TSP will consider when forecasting Demand during the Operational Programming and Control Phases.
