The future of nuclear financing: A turning point for investment in clean energy

In the face of escalating climate challenges and the pressing need to achieve net zero emissions, nuclear energy is witnessing a resurgence in interest as a critical component of the global energy mix. To meet the International Atomic Energy Agency's (IAEA) high case projections for nuclear capacity by 2050, a substantial increase in investment is required. This blog explores the evolving landscape of nuclear financing and the potential turning points that could make nuclear projects more attractive to investors.

The need for enhanced nuclear investment
According to the IAEA, investments in nuclear energy stand at around US $50 billion annually. However, to meet future capacity goals, this figure needs to increase to at least US $125 billion per year. Tripling existing nuclear capacity could require over US $150 billion annually, necessitating that nuclear projects demonstrate bankability by effectively managing financial risks. Construction and investment costs account for a large proportion of the expenses, making it crucial to mitigate risks associated with cost overruns and delays.

Challenges in financing nuclear projects
Financing nuclear projects has traditionally been challenging due to:

• High capital costs: With construction and investment costs on some projects forming two-thirds to 75% of the total cost per megawatt-hour, nuclear projects are highly sensitive to fluctuations in capital costs and construction schedules. Cost overruns and project delays have been seen on many recent large-scale nuclear projects, creating an apprehensive investment environment.
• Environmental and public perception issues: many commercial bank policies historically rejected nuclear financing on this basis.
• Policymaker hesitancy: there has been a lack of continuous government commitment to the development of large scale nuclear in some countries, which introduces uncertainty for investors and financiers. Development cost for nuclear projects tend to be significantly lower in countries where there is consistent policy for nuclear. 

Changing dynamics in nuclear financing
The landscape is, however, shifting. There are several factors converging which could potentially transform nuclear financing:

1. Growing imperative for carbon neutrality: The urgency of achieving net zero goals is pushing nuclear energy to the fore. Reports from the Intergovernmental Panel on Climate Change emphasise nuclear energy’s role in all scenarios that achieve carbon-neutrality by 2050.
2. Geopolitical and energy security concerns: Recent geopolitical shifts have renewed focus on energy security. Countries like Germany, who are opposed to nuclear as part of their energy mix, are reconsidering.
3. Grid resilience: Closure of aging nuclear fleet and other baseload power has created a renewed focus on grid resilience. 
4. Evolving power demand: Increasing electrification and the growth of AI and data centres have significantly influenced power demand, leading investors to explore nuclear's role in providing low-carbon solutions via onsite small modular nuclear reactors (SMRs) and other advanced nuclear technologies.
5. Corporate and collaborative investment models: new, collaborative models and public-private partnerships are being used in some cases to share risk distribution, enhancing nuclear project feasibility. 

Innovative financing mechanisms to support nuclear development include:

1. Government involvement: Extensive government financing, export credit agencies, and multilateral institutions play crucial roles by offering funding and risk mitigation.
2. Regulatory reforms: Recent reforms, like the 2024 European Market Reform, introduce stable revenue mechanisms, such as Contracts for Difference (CfDs), which mitigate revenue risk.
3. RAB Model: The Regulated Asset Base (RAB) approach, being trialled for projects like Sizewell C, shares construction and operational risks between investors and consumers, enhancing project viability.

The road ahead
As the global community strives for sustainable energy solutions, nuclear energy stands as a promising avenue. By leveraging government support and innovative financial models, the nuclear sector has the potential to secure the necessary investment and play a pivotal role in the transition to a low-carbon future.

Conclusion
Nuclear energy is at a critical juncture. While challenges remain, the blend of technological advancement, greater clarity governmental support, and innovative financing provides a promising pathway for nuclear projects as a key part of the global low-carbon energy mix. As we progress, these developments could redefine how nuclear energy positions itself as a cornerstone of global clean energy initiatives.
