Electrification of Slovak towns and villages progressed very slowly due to the
bad economic situation between the two wars. According to statistics, there
were 167 towns and villages electrified in 1922. As of 1928 there were of 7 %
of settlements electrified. By the end of 1939 electrification level in
Slovakia reached only 27 %. After the end of the World War II (in 1946) the
total of 40.2 % of settlements in Slovakia were electrified.
The total electricity consumption in Slovakia in 1940 amounted to 509 000 MWh
with the peak of 137 MW that represent specific consumption of 143.8 kWh per
year per capita. In the first years after the war, during the reconstruction of
war damages, there was a slump in electricity consumption. However, as soon as
in 1950 the total consumption in Slovakia was about 1 million MWh due to an
extensive industry development programme.
The dynamic growth of large-intake electricity consumers went on in 60’s, when
industrial development was focused on manufacturing industry that reduced
year-to-year rise of electricity consumption by the large consumers.
Retail electricity consumption dynamically increased in parallel with
completion of the Slovak territory electrification and with start of housing
estate construction. There was a year-to-year rise of retail electricity
consumption of 10 % till 1975.

The total electricity generation in Slovakia in 1945 amounted to 310 GWh, out
of which 169 GWh were generated by SE, national company, and 141 GWh in
industrial power plants. In spite of the generation facilities construction,
the transmission system uneven balance in Slovakia continued, and electricity
had to be transmitted from Bohemia as well as imported from abroad. Electricity
generation significantly increased only after the large generation facilities
were built up (Novaky, Vojany 1, Vojany 2 thermal power plants, Bohunice
nuclear power plants).
