> Enel’s net domestic electricity generation fell by 7.3% in 2006. This decrease
in production is primarily related to thermal power generation;
> electricity purchases fell by 7.8% in 2006. This decrease is related to lower imports
and smaller sales on the regulated market;
> sales to wholesalers fell by 13.2% from the previous year. The decrease is
substantially attributable to the decrease in volumes sold on the Power Exchange
and to the Single Buyer, partially offset by an increase in sales to resellers.
As for overall sales to the final consumer, Enel’s market share for 2006 came to
45.1% (about 47.8% for 2005). In particular:
>sales on the regulated market fell by 7.2% for 2006, primarily the result of market
liberalization, which, however, gave rise to an increase of 20.5% in sales on the
free market;
> electricity transported on Enel’s distribution network for 2006 increased by 1.6%.
Excluding from the 2005 figures the additions made during the periods in question
for electricity that was physically transported in previous periods but commercially
recognized in 2005 (some 1.5 billion kWh), this rise came to about 2.2%.
