Notes

  • Graph's data is taken from statistics available at Terna S.p.A. web site, especially "Historical data", "Production" and "General data".
  • 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).

  • Other Renewables entry represent the sum of sources other than Hydro.
  • These are gross productions, that is electric energy coming out from generators without deducting ancillary services consumptions.
  • 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.
    [ 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).
