  • Decreased profitability in the electricity sector can largely be attributed to the lower hydraulicity of the hydroelectric plant in Calabria, the lack of the essential requirements previuosly recognized in the thermoelectric plant in Monfalcone (carbon and fuel oil), as well as the deconsolidation of the economic results in terms of the gross operating margin of the San Filippo del Mela plant in Sicily (fuel oil) which exited the perimeter regulated by Tolling Agreement contracts with Edipower.
