Sweden to Build New Nuclear Power Plants for the First time in 50 Years
varberg, Sweden – In a landmark decision signaling a meaningful shift in energy policy, Sweden will begin construction of new nuclear power facilities, the first in 50 years. The declaration came during a press conference at the Ringhals nuclear power plant yesterday, August 21, 2025, with Prime Minister Ulf Kristersson at the helm.
Vattenfall‘s Investment in Small Modular Reactors
The initiative follows an announcement earlier in the day by Vattenfall, Sweden’s state-owned energy company, detailing plans to invest in small modular reactors (SMRs). The project aims to generate 1,500 megawatts of power, with potential for expansion to 2,500 megawatts. All of you who are a little geeky interested in energy know that it corresponds to two large conventional nuclear power plants,
stated Prime Minister Kristersson.
The Swedish government is contributing financially to the project, demonstrating a long-term commitment to nuclear energy. Industry partners are also expected to participate as co-owners. Kristersson emphasized this is a ancient chance
for Sweden’s energy future.
Vattenfall is evaluating proposals from two leading technology providers: American firm GE Vernova and British company Rolls-Royce. The company will choose between constructing five reactors from GE Vernova or three from Rolls-Royce. Anna Borg, Vattenfall’s CEO, explained that these are light water reactors, a well-established technology.A reactor from Rolls-Royce produces about as much electricity as the first reactor in Oskarshamn did,
she noted.
Did You Know? Sweden previously phased out nuclear power following a 1980 referendum, but public opinion has shifted in recent years due to concerns about energy security and climate change.
Political Support and National significance
The decision has garnered broad political support. Jimmie Åkesson, leader of the Sweden Democrats, hailed the move as a big step to restore stability and planability in the system.
Energy Minister Ebba Busch (KD) described it as the next major step in the history of Swedish nuclear power
and a key element in the global race for nuclear power.
Simona Mohamsson also characterized the day as historic.
Sweden’s commitment to ambitious climate goals was a central theme. Mohamsson stated, If we are to continue to be a leading country in the climate change, we must secure investments in fossil-free and supply-proof energy production.
Finance Minister Elisabeth Svantesson (M) underscored the importance of nuclear power to Sweden’s economic strength, stating, We are a nuclear country, it has been an important part of building Sweden rich and strong and will continue to be.
Projected Capacity and technology
| Component | Details |
|---|---|
| Total Projected Capacity | 1,500 – 2,500 Megawatts |
| Reactor Type | Small Modular Reactors (SMRs) – Light Water Reactors |
| Potential Suppliers | GE Vernova (USA), Rolls-Royce (UK) |
| Reactor Options | 5 x GE Vernova or 3 x Rolls-Royce |
Pro Tip: SMRs offer advantages over traditional large-scale nuclear plants, including reduced construction time, lower upfront costs, and enhanced safety features.
The Future of Swedish Energy
This investment represents a significant reversal of Sweden’s previous nuclear phase-out policy.The decision reflects a growing recognition of nuclear energy’s role in achieving climate neutrality and ensuring a stable energy supply. The move also aligns with a broader European trend toward reconsidering nuclear power considering energy security concerns exacerbated by geopolitical events. According to the World nuclear Association, nuclear energy currently provides approximately 30% of Sweden’s electricity [[1]].
What impact will this investment have on Sweden’s carbon footprint,and how will it influence energy policy in neighboring countries? Will the adoption of SMR technology accelerate globally as an inevitable result of Sweden’s commitment?
Background on Swedish Energy Policy
Sweden has long been a leader in renewable energy,with a significant portion of its electricity generated from hydropower and wind power. However, concerns about grid stability and the intermittency of renewable sources have prompted a reevaluation of nuclear power. The decision to invest in SMRs is a pragmatic response to these challenges, offering a reliable and low-carbon energy source. the country’s energy market is also heavily influenced by its membership in the Nordic power market, Nord pool, which connects Sweden, Norway, Denmark, and Finland.
Frequently Asked Questions about Sweden’s Nuclear Investment
- what are Small Modular Reactors (SMRs)? SMRs are nuclear reactors that are smaller in size and can be manufactured in factories and transported to the site for installation, reducing construction time and costs.
- Why is Sweden building new nuclear power plants now? Sweden is responding to the need for a stable, fossil-free energy supply and to meet its ambitious climate goals.
- Who are the key players in this project? Vattenfall is the primary investor, with GE Vernova and rolls-Royce as potential technology suppliers.
- How much electricity will these new reactors generate? The project aims to generate between 1,500 and 2,500 megawatts of power.
- what is the timeline for completion? while a specific timeline hasn’t been announced, construction is expected to begin in the near future, with the first reactors potentially operational within the next decade.
