Nine Swedish energy researchers find that new nuclear power is not needed.

 The government has stated that “physics is heavier than politics” .
Unfortunately, on several occasions, misconceptions have been spread about
the physical capabilities of the power system.

It is not true that it costs 8 billion to regulate and balance wind power, or that new nuclear power is necessary for a stable electricity system, write nine energy researchers
from north to south. The need for new nuclear power. “New nuclear power
is necessary for a stable and reliable energy system, for both consumers
and businesses,” stated Finance Minister Elisabeth Svantesson (M) in
November 2023.

It goes without saying that a stable and reliable energy
system is needed. Svenska kraftnät has studied various alternatives in its
reports, the latest of which is “ Long-term Market Analysis 2024 ”. It
shows that a Swedish fossil-free power system with more than twice as much
consumption as today, and without nuclear power, can achieve reliability at
the same level as today.

The solution is called flexibility, where electric
cars, hydrogen storage and electricity trading contribute, among other
things. Nuclear power is important for stability today, as it contributes a
buffer in the form of rotational energy. This buffer ensures that balance
is maintained during the first seconds after, for example, a sudden stop in
another nuclear power plant. Nuclear power also helps to ensure that we get
an appropriate voltage on the power lines.

But this can also be arranged in
other ways. In the Nordic countries there is a system that activates
batteries, among other things, in seconds, so that stability is achieved
even with lower amounts of nuclear power. There is also a technological
development where Swedish industry is at the forefront. There is an
incredibly large export market, since the whole world will get more solar
and wind power when the existing fossil power plants are phased out. This
shift is happening now because solar and wind power have steadily fallen in
price and can be built quickly.
