  • Note: All variance percentages shown refer to the same period in the previous year.
  • (1) Allocation of production units according to primary fuel.
  • (2) Rolling year: cumulative value in the last 365 days, or 366 days in leap years.
  • (3) Pure pumped storage + mixed pumped storage estimate.
  • (4) Includes operation in open cycle mode.
  • (5) Includes biogas, biomass, marine energy and geothermal. The values of increase and rolling year include waste up until 31 December 2014.
  • (6) The increment and rolling year values include waste up to December 31, 2014.
  • (7) Generation included in other renewables and cogeneration on 12/31/2014.
  • (8) Positive value: incoming energy; negative value: outgoing energy.
  • (9) Positive value: import balance; negative value: export balance
  • (10) After factoring in the influence of seasonal and working patterns
  • (11) Includes hydro, wind, solar photovoltaic, solar thermal, other renewables and renewable waste.
  • (12) Percentage of probability of exceeding the index value.
