Data defining sequential events in the utility system is obtained, each event identified by three coordinate values: hour of day, recorded temperature, and resource usage. A three-dimensional topological surface is generated from the coordinate value, by plotting the resource usage against the hour and temperature in a three-dimensional space. A polynomial equation having calculated coefficients and a highest degree of six for each variable is generated to define the topological surface, wherein the polynomial equation expresses the resource usage as a tenth-degree polynomial function of hour of day and temperature. A future load on components of the system at a particular temperature and hour of day is determined by applying the coefficients to the coordinate values for the particular temperature and hour, and modifying the functionality of components of the electrical utility system based on the determined future load. ## Claims ### Claim 1 A method for weather adjustment of an electrical utility system, comprising: obtaining data defining a plurality of sequential events in the electrical utility system, each event identified by three coordinate values, the three coordinate values being hour of day, recorded temperature, and resource usage of the electrical utility system;
