Notes

  • Graph's data is taken from statistics available at Terna S.p.A. web site, especially "Historical data", "Production" and "General data".
  • Gross Domestic Consumption is the sum of the various inland gross productions (electric energy coming out from generators without deducting ancillary services consumptions) and net imports with foreign regions (+imports, -exports).
  • Hydro (natural) is the production minus energy originating from pumped water. Data before 2007 are estimated with good accuracy deducting 74% of pumping energy consumptions from overall hydro values (average efficiency rate of the process).

  • 2012 data are final values.
  • 2013 data are estimated on partial results recorded for january-june period in Terna's monthly reports. It should be noted that these reports provide net production data whereas in graph you see gross values. The detailed renewable production is showed in the specific graph.
    [ Update 23-01-2014 ] - Estimated data don't undergo significant changes after january-december results (provisional anyway), so graphs will be updated only when Terna will release final data (coming summer).
  • Light green dotted line represent the 2020 renewable production target (26,4% of GDC) as stated in National Renewable Energy Action Plans (NREAP; Piano di Azione Nazionale, PAN, in italian) set by European Directive 2009/28/EC.
    Green dotted line represent the 2020 renewable production target (35-38% of GDC, 37% in graph) as declared in Strategia Energetica Nazionale (SEN), an energy planning document presented by government on march 2013.
    European Directive requires that target (PAN) is computed with specific multi-year averages for wind and hydro whereas here actual production values are used. So reaching the target in graph doesn't mean reaching the formal target but it means we are close. You can find formal production values on GSE web site in the SIMERI section at "Quota Nazionale" entry.
