Title: ESTIMATING THE IMPACT OF WEATHER IN ELECTRICITY BILLS
Abstract:
A method for determining the impact of weather on electricity costs includes executing (21) at least one regression model to calculate (22, 23) regression coefficients for one or more regressor variables from a set of weather and energy usage data; and splitting (24) energy usage associated with weather from energy usage not associated with weather based on the regression coefficients and confidence intervals calculated for the one or more regression models, wherein the one or more regressor variables include temperature, heating degree days (HDDs), and cooling degree days (CDDs), HDDi = max{ Tb Ti, 0}, CDDi = max{ Ti Tb, 0}, Ti is an average temperature for day i, and Tb is a baseline temperature selected to separate an amount of energy used for heating and from an amount of energy used for cooling, and the energy usage not associated with weather is a total energy usage minus the energy usage associated with weather.
