This paper proposes an optimal calculation method for calculating economical ESS usage in the situation where multiple customers use a single common ESS facility together. The ESS usage of each customer is calculated using the capacity and electricity rates of each customer. However, as the number of customers increases, the ESS usage becomes very inefficient because the calculation of the nth order matrix is performed. Therefore, in this paper, a method that can be calculated by converting a 3-D matrix into a 2-D matrix is proposed when the number of customers is three or more. In this method, since ESS usage is determined by the power rates of the two customers initially calculated, the order of the calculated customers must be calculated in the order of the customer's contract capacity. This algorithm has the advantage of being calculated as a 2-D matrix even if the number of customers increases.
