Data Required by the TSP for Operational Demand Forecasting 4.2.4.1 Each User shall supply data to the TSP in relation to that User’s Demand and Active Energy relating to various operational phases as stated in the relevant parts of this section. Figure 4.1 highlights timescales involved with each Phase. Chapter 4 - Operating Code The Saudi Arabian Grid Code Updated Version: May 2024 Figure 4.1. Description and time flow of various operational planning phases Operational Planning Phase (i) Distribution Entities and Directly-connected Customers provide forecast of Active Demand and Energy for the next 5 years to the TSP. (ii) The TSP develops 5-year Demand Forecast Programming Phase (i) Each first day of business week, Distribution Entities and Directly-connected Customers provide to the TSP, MW profile, on hourly and Connection Point basis, of Demand Control for the next 8 weeks (ii) The TSP develops 8-weeks Demand Forecast Control Phase (i) Distribution Entities and Directly-connected Customers provide to the TSP Demand changes, on hourly and Connection Point basis. (ii) The TSP develops day-ahead Demand Forecast Post-Control Phase Distribution Entities and Directly-connected Customers provide to TSP, on hourly and Connection Point basis, the actual Demand Control carried out. End Year 0 Start of Year1 By End March 8 weeks ahead of Schedule Day Day ahead of Schedule Day Subsequent Day Schedule Day Chapter 4 - Operating Code The Saudi Arabian Grid Code Updated Version: May 2024 4.2.4.2 Operational Planning Phase (Year 1 to Year 5) (i) No later than 31 January each year, the TSP shall notify each User in writing of the following (for the current year and for each of the succeeding five (5) calendar years: (a) the date and time of its expected annual peak Demand at Annual Maximum Demand Conditions; and (b) the date and time of its expected annual minimum Demand at Average Conditions. (ii) By end of March each year, every User, as further elaborated below, shall provide to the TSP in writing, the forecast information listed below for the current year and each of the succeeding five (5) calendar years: (a) for each Distribution Entity (summed over all Connection Points) and for each Directly-connected Customers (at the Connection Point), the hourly forecast profile of Active Power Demand for the day of that User’s Maximum Demand and for the specified day of the annual peak Demand of the TSP, both at their respective Annual Maximum Demand Conditions; (b) for each Distribution Entity (summed over all Connection Points) and for each Directly-connected Customer (at the Connection Point) the annual Active Energy requirements for Average Conditions segregated into different usage categories such as, residential, commercial, Government, industrial, agriculture, street lighting, hospitals, etc., wherever practicable; (c) for each Distribution Entity (summed over all Connection Points) and Directly-connected Customer (at the Connection Point) the hourly forecast profile of Active Demand for the specified day of the minimum Demand of the TSP at Average Conditions; (d) individual Connection Point Demand (Active Power) and Power Factor at Annual Maximum Demand Conditions for the annual peak hour at the Connection Point and at the specified hour of the annual peak of the TSP Demand; and Chapter 4 - Operating Code The Saudi Arabian Grid Code Updated Version: May 2024 (e) individual Connection Point Demand (Active Power ) and Power Factor at Average Conditions at the specified hour of the annual minimum Demand of the TSP. (iii) If the Busbar at a Connection Point is expected to be operated in separate sections, separate sets of Forecast Data for each section shall be provided to the TSP. (iv) The TSP will use the information supplied to it in preparing Forecast Demand information for the next five years and for use in its operational planning. 4.2.4.3 Programming Phase (1 to 8 weeks ahead of the Schedule Day) For 1 to 8 weeks ahead of the Schedule Day, each Distribution Entity and Directly-connected Customer shall supply to the TSP, in writing, by 10:00 hours each first day of business week, hourly MW profiles of the amount and duration of their proposed use of Demand Control which may result in a Demand change of five (5) MW or more on an hourly and Connection Point basis. 4.2.4.4 Control Phase Each Distribution Entity and Directly-connected Customer shall inform the TSP of any Demand Control which may result in a Demand change of five (5) MW or more averaged over any hour on any Connection Point which is planned after 10:00 hours, and of any changes to the planned Demand Control notified to the TSP prior to 10:00 hours as soon as possible after the formulation of the new plans. 4.2.4.5 Post-Control Phase Each Distribution Entity and Directly-connected Customer shall supply to the TSP in writing by 10:00 hours each day Active and Reactive Power data in terms of MW profiles for the previous calendar day of the amount and duration of actual Demand reduction achieved from the use of Demand Control of five (5) MW or more (averaged over any hour on any Connection Point), on an hourly and Connection Point basis.
