recorded in the probability zone, which is not taken into account when calculating electric power provision (2–3%). Such a period when minimum flows reoccur
comprises around 50 years.
In Romania, in the last two years (2011 and 2012), the low amounts of precipitations entailed a decrease in hydropower by 4 and 5 TWh, respectively, compared
to an average hydrological year, which led to a loss of 1200 million EUROS in the
hydroelectric sector (Table 15.7). The tributary flows on national rivers, which produce electric power, are lower by 40–60%, than the flows estimated for a normal
hydrological year.
Globally, 2.1 million GWh are produced annually, which represents between 16
and 18% of the global electricity consumption. The exploitable potential is 6–7%
higher. Within an average hydrological year, Romania produces 17.33 TWh, which
means 35% of the consumption. The potential in the domain is almost double [47].
In the drought period of the year 2011–2012, Hidroelectrica S.A. produced only
13 TWh.

For a correct understanding of the phrase “normal hydrological year”, it is necessary
to review several hydrological terms accepted by the international forums and by the
specialized institutions in Romania [14, 50–52, 54]. A hydrological year represents
