The demand for electrical energy on the Spanish peninsula in December, after having factored in the seasonal and working patterns, dropped 3.1% with respect to the same month last year. Gross demand for the whole month of December is foreseen to reach 21,163 GWh, 3.2% lower than in the same month of 2011. These percentages are lower than those recorded in the initial preliminary report due to the mild temperatures experienced in the last half of this month.

In 2012 as a whole, working with up-to-date data and having factored in the seasonal and working patterns, consumption will be 1.9% below that registered in 2011. The forecasted gross demand for electrical energy in this period will reach 251,699 GWh, 1.4% less than the same period last year.
