The document provides an overview of Enel SpA's 2008 results and 2009-2013 plan. In 2008, Enel saw increases in revenues, EBITDA, EBIT, and net income compared to 2007, despite challenging market conditions. Enel aims to strengthen its financial stability and reduce net debt through measures such as asset disposals, a rights issue, optimized capex, and an improved dividend policy in order to maintain its A-/A2 credit rating.
