AUSTRIA (at)
Among other factors, peak demand is significantly influenced by climatic conditions since high power
demand is expected during winter months (December/January). Usually a decline in temperature of
1 degree seems to lead to an increase of the peak demand in the range of 50 MW to 100 MW depending
on various other factors (season, level of temperature, etc.)
The main part of the “foreseeable not available capacity” (Table 4.1) is the reduced capacity of run
of river plants, caused by smaller water flow of rivers in the winter season or too much water in case
of flooding. An additional part is less power capacity in consequence of an increased heat or steam
production in cogeneration units or to increase imports. Sources for the data in table 4.1 are based on
UCTE publications.
GERMANy (de)
When evaluating generation programmes it is assumed that a certain amount of the generating
capacity is not available during the period of maximum peak demand due to low hydro output during
the winter period, devoted capacities to heat production in CHP stations or a discontinuous supply of
wind power stations. Furthermore a reserve has to be provided for the case of shutdowns and demand
variations due to the economic situation or caused by the weather.

Table 4.1: Foreseeable, not available capacity is associated to hydro power plants stations, since
their effective capacity is heavily dependent on hydrology, and to the irregular capacity contributions
of electricity production from RES. Peak demand data does not include the one corresponding to
autoproducers’ self-consumption.

Export and import prognosis should be taken as an estimate as power exchange depends on the future
market situation and on decisions taken in several countries. It is assumed that net import will turn into
slight net export due to assumed investments in Finland.
New sea cables between Finland and Sweden (Fenno-Skan 2) and between Finland and Estonia (Estlink)
are taken into account in the scenario.
LITHUANIA (lt)
During the peak load in the energy system, the capacities of small hydro power plants, wind power,
other renewable and to some extent of the autoproducers are not taken into consideration.
LUXEMBOURG (lu)
Luxembourg is still a net importing country for electricity, as it is also for all other energy sources.
