The demand for electrical energy on the Spanish peninsula was 20,432 GWh in the month of November, representing a drop of 6.2% with respect to the same month last year. This drop in demand was influenced mainly by the unusually mild temperatures registered during November. After factoring in the effects of seasonal and working patterns, the adjusted demand showed a fall of 3.6%.

In the first eleven months of the year, demand reached 228,954 GWh, 4.8% less than in the same period in 2008. Factoring in the effects of seasonal and working patterns, the adjusted demand showed a fall of 4.8% during the period.
