NUCLEAR INDICATORS

The installed power of nuclear energy corresponded to 5.7% of the total installed capacity of the Group in 2020. The production of electricity from nuclear energy has accounted for 14.9% of total production (not including steam generation) and revenues of nuclear energy production are equivalent to 2.6% of the Group's total revenues in 2020.

(*) Nota Iberdrola joint value calculated on the WANO UA7 (24 months) indicators of nuclear power plants weighted by Iberdrola share power and ownership. Indicator does not take into account the Sta. María de Garoña NPP which was not included on WANO indicators during 2013.

(**) Nota Iberdrola joint value calculated on the events notified by nuclear power plants weighted by Iberdrola share power and ownership. Notified events according to the Safety Instructions IS-10 of the Nuclear Safety Council.

(***) Nota Max. and Min. Values for Iberdrola nuclear fleet for the Effective Dose for the Critical Group. Year value corresponds to the accumulated one until December (12 consecutive months). Each value is calculated taking into account actual releases and the impact of these over an ideal individual with the worst conditions in terms of exposure pathways (the sum of the worst case for every pathway), which represents very conservatively to the most exposed individual of the local community.
Unit I and unit II of Almaraz are considered separately since 2013 to increase the accuracy of the indicator. This consideration modify retrospectively the indicator.

(****) Nota Iberdrola joint value calculated on the WANO CRE indicators of nuclear power plants weighted by Iberdrola share power and ownership and considering its fuel cycle. Indicator does not take into account the Sta. Mª de Garoña NPP which it is not included in WANO indicators since 2013.

(*****) Nota Iberdrola joint value calculated on the amount of generated waste of low and medium activity and packed in each plant weighted by Iberdrola share power and ownership.

(*******) Nota Iberdrola joint value calculated on the amount of initial U of each element in the fuel pool at each plant weighted by Iberdrola share power and ownership.

(*******) Nota Iberdrola joint value calculated on the amount of initial U of each element discharged annually in the fuel pool at each plant weighted by Iberdrola share power and ownership.

(********) Nota Spent Fuel from Maine Yankee, Yankee Rowe and Connecticut Yankee is considered in this indicator. These spent fuel elements are stored in one ISFSI per site, waiting for USA Federal Government to remove it.
