The power grid must be expanded at a faster rate here and now, according to Vattenfall's CEO Anna Borg.
Otherwise, the risk is that investments will end up somewhere else, she says.
The government's goal is to have two new large-scale nuclear reactors in place by 2035.
The goal has been described as "reasonable but challenging" by the government's own nuclear coordinator.
A description that Vattenfall's CEO Anna Borg agrees with, as long as the state takes on part of the risk.
Two reactors by the mid-2030s, and more reactors eventually, I think is extremely important for the Swedish energy system, she says.
However, she believes that it is not being invested in at a "sufficient rate" here and now.
If we cannot achieve an expansion in the near future, and meet the increased demand from Swedish industry, then the risk is that some of the investments will end up somewhere else, she says.
In that case, Sweden would not have any need in the future for the system that is currently being invested in, according to Borg.
It must come both now and later, and I don't feel that the pressure is on yet. There are many projects that can deliver. Some are being built, but it would need to go much faster, she says.
According to Anna Borg, it is important to complement the investment in nuclear power with wind power, both at sea and on land.
Wind power has the ability to deliver earlier, simply because these projects have come further and because it takes less time to build, so you need to do both parts, she says.
