In 2013, net electricity generation by the Division amounted to 61,022 million kWh, a decrease of 4.6% compared with 2012. The change was reflected in a sharp reduction in conventional thermal generation in Italy, which contracted by 7,085 million kWh (-14.6%), attributable to the decline in demand for electricity and the increasing weight of renewables in the national energy mix, partially offset by the difference in the contribution of the Marcinelle plant in Belgium, which is operated under a tolling agreement and entered service in the 2nd Quarter of 2012.

In these conditions, the improvement in water availability boosted hydroelectric generation, which expanded by 3,937 million kWh.

Enel Open Data

Gross thermal generation in 2013 totaled 46,009 million kWh, a decrease of 7,140 million kWh (-13.4%) compared with 2012. The decrease was seen across all the major fuel types and was essentially connected with the decline in weight of conventional thermal generation in the Italian fuel mix, in an environment of falling demand for electricity as a result of the recession in Italy.

More specifically, the decline in gas generation was due to the reduction in the use of that fuel in combined-cycle plants, while the decrease in generation from coal is attributable to the reduction in the use of certain units of the Brindisi Sud plant and technical stoppages for maintenance at the Torrevaldaliga Nord plant.
