The demand for gas from the Spanish industrial sector increased slightly during the year, but with an overall result of little relevance: the positive rate (2.1%) is below the growth of the Spanish economy as a whole. This evolution benefited from a recovery in cogeneration during the second half of the year as a result of the new legislation that regulates the production of electricity with this technology. The said legislation outlines a more realistic scenario than before by allowing, for example, payment for all the electricity produced (not only the electricity sent to the grid), dumping all the production on the grid and considering the costs of the primary energy used for cogeneration. At the end of 2007, the power installed in cogeneration exceeded 6000 MW. And if consideration is given to the production of electricity in cogeneration with gas, as occurred in 2005 and 2006, in 2007, natural gas was the energy most widely used as a primary source for the production of electricity in Spain (see the table on the National electricity balance by energy sources in the chapter titled "Energy in Spain" on page X).

At present, the natural gas sales corresponding to the industrial sector in Spain represent half the total.
