This paper presents an empirical analysis on the residential demand for electricity. This analysis has been performed using aggregate panel data at the province level for 47 Spanish provinces for the period from 2000 to 2008. The purpose of this empirical analysis has been to highlight some of the characteristics of the Spanish residential electricity demand. Particular attention has been paid to the influence of price, income, and weather conditions on electricity demand. The estimated short and long-run own price elasticities are, as expected, negative, but lower than 1. Furthermore, weather variables have a significant impact on electricity demand.
