THE POWER SUPPLY AND THE ROLE OF NUCLEAR POWER IN SWEDEN.

The power supply
Almost all electric power in Sweden is now produced in hydro power and nuclear 
power stations. Nominal capacity for each of the two types of energy is 63 TWh per 
year. Oil and coal-fired back pressure units (for co-generation of electricity and heat 
for district heating) have a nominal capacity of 5 TWh per year. Oil-fired units solely 
for power production, and gas turbines are used only in extreme peak hours. Coal or 
gas are not used solely for power production in Sweden.
The power consumption in Sweden 1985 was inclusive losses 130 TWh (i.e. total 
137 TWh minus export 7 TWh). For the third year in a row, the growth in electricity 
consumption was close to 10%. The predicted growth is lower for the coming years.

The power situation in Sweden can be characterized in the following way:
- The annual power consumption is 16,000 kWh a head. Sweden has the fourth
highest value in the world after Norway, Canada and Iceland.
- The annual nuclear power production of 7,600 kWh a head, is by far the largest
in the world.
- Oil consumption has halved during a ten year period, while electricity
consumption has risen by a factor 1.7.
- Consumer prices for electricity are among the lowest in the world.

Nuclear power production
The expansion of hydro power from start to 63 TWh a year took 100 years. Nuclear 
power started in 1965, and 20 years later the capacity is 63 TWh a year. The first 
nuclear power unit started operation in 1972. Thirteen years later, in 1985, nuclear 
units number 11 and 12 began operation. There are no plans for building more 
nuclear units.

Nine of the reactors are BWRs, all delivered by ASEA-ATOM, Sweden. The other
three reactors are PWRs and were delivered by Westinghouse, U.S.

Almost all the turbines were delivered by ASEA STAL. Sweden.
