Key summary

At the IAEA–United States Regional Workshop on Scaling SMR Deployment, held by the Office of Atoms for Peace (OAEP) on November 3, Mr. Neal Mann and Mr. Nicolas Stauff from Argonne National Laboratory (ANL), supported by the U.S. Department of Energy, presented the results of a macroeconomic simulation model. The model projects that global electricity demand will increase by 25-50% by 2050. The proportion of nuclear energy worldwide is expected to grow significantly, potentially up to 6 times, to meet this demand, particularly in Asia and Europe. The study used three types of modeling tools: GCAM, AEF, and IMPLAN, considering variables such as the growth of data centers, reactor costs, and policy goals. The analysis indicates that while solar and wind energy will grow, coal consumption will decrease significantly. Nuclear energy in the United States could increase by up to 33% or decrease to 12%, depending on economic conditions.

Business Insight — Publisher’s Perspective

The ANL study's projection of a significant global increase in nuclear power capacity by 2050, driven largely by rising demand from data centers and heavy industry in Asia, suggests that businesses in Thailand involved in energy infrastructure or related manufacturing may need to monitor long-term shifts in the regional energy mix. While the report indicates coal consumption will decline sharply, it also notes that real-time grid stability during extreme weather might require higher backup capacity from fossil fuels or nuclear sources than initially modeled; this could mean that Thai manufacturers relying on stable power supplies should consider potential volatility in future energy sourcing strategies. The mention of heavy industry growth in Asia implies that export-oriented businesses in Thailand serving these sectors might face evolving requirements for low-carbon energy solutions, though the study does not guarantee specific regulatory changes or immediate market entry barriers. Companies distributing industrial equipment or components related to nuclear or alternative energy systems could see potential opportunities, but any such moves would depend on how global and regional policies adapt to the predicted six-fold increase in nuclear power share without assuming that current regulations will automatically facilitate this transition.
