YEAR CHARACTERIZATION
Electricity consumption in 2009 was 49.9
TWh, which is 1.4% lower, or 1.8% corrected
for the effect of temperature and the
number of working days, than the preceding
year (the first fall since 1981). Consumption
at the regulated tariff fell to 82% of the
total.
Peak power demand on the public grid
occurred on 12 January and amounted to
9,217 MW, which is 100 MW above the
previous all-time record set in December
2007.
Hydroelectric energy capability was 23%
below ordinary levels, but hydroelectric
generation was 23% up on the preceding year
and supplied 14% of consumption. Thermoelectric generation was similar to the preceding year, accounting for 48% of consumption.
Special status generation (PRE) grew 25% and
accounted for 29% of consumption, 15% of
which originated from wind power, where
capacity was boosted by 700 MW.
The import balance was the lowest since
2003, accounting for 9% of consumption.
The highlights in the development of the
national transmission grid were: the con-
struction of the Falagueira-Estremoz line and
the opening of Estremoz substation - significant enhancements to improve service
quality in inland areas of the Alto Alentejo
region, the opening of Tábua substation - to
handle PRE generation, and also the operational start-up of Lagoaça substation (Freixo
de Espada à Cinta) - the first step in significantly increasing exchange capacity with the
Spanish national grid, which is to be
achieved with the completion of the new 400
kV interconnection in this zone. The autotransformation capacities of the Falagueira
and Ferreira do Alentejo substations were
also strengthened with a new unit installed
in each. At Falagueira, this new unit played
a role in increasing the renewable energy
handling capacity of the Beira Interior axis,
and at the Ferreira do Alentejo substation it
helped to raise the interconnection capacity
with Spain. The operational start-up of Lares
combined cycle power station (2x435 MW),
which is connected to the grid through
a double 400 kV line between the power
station and Lavos substation, was also
relevant.
In terms of quality of service the national
grid continued to perform well. The Equivalent Interruption Time was 0.42 minutes (the
best value ever).
