The external power supply for a diamond mine is selected by feasibility studies of all alternatives. The key governing factors of electric power supply engineering should be the characteristics of power sources and consumer in terms of reliable uninterrupted supply and safety of use. In this respect, the present authors substantiate the method for the determination of design values and load factors with regard to actual energy consumption modes in open pit diamond mines in the permafrost zone. For the RF Standard: Design Rules for Open Pit Diamond Mines in the Permafrost Zone (Power Supply) under development, the methods of accounting for specific energy consumption, energy demand factor, as well as average capacity and deviation from mean design load are recommended. The proposed procedures differ from the standard technical documentation now in force not in the structure but in the content. The newly offered average and maximum capacities, as well as coefficients of peak and shape of power system load curve are reflective of the actual picture of power consumption as they are obtained from processing of representative statistics on energy demand of various production processes and departments of diamond mines operating in the permafrost zone. The statistical method using two integral characteristics, namely, integral average load and general standard deviation, offers higher accuracy. This method provides an accurate value of the customer contract demand in the time of peak load in the electric power system. Furthermore, the method is advantageous for the maximum agreement of the calculated and actual load.
