Lately, I've been focusing on the top utility stocks in the power sector and found that nuclear energy is definitely worth paying attention to. As AI data centers, electric vehicles, and urbanization drive a surge in demand for clean electricity, traditional energy sources are falling behind.

I noticed that two companies' performances in this wave are quite interesting—Constellation Energy and Ameren. The former is the largest nuclear power operator in the U.S., with a capacity factor of 94.8% for its nuclear fleet, which is a strong indicator. They generate 10% of the United States' carbon-free electricity, which is no small figure. The latter has relatively smaller nuclear assets (Callaway Nuclear Station accounts for 24% of its capacity), but is more aggressive in deploying next-generation nuclear technology and energy storage, planning to add 1,500MW of nuclear capacity by 2040.

From a financial perspective, Constellation's ROE is as high as 21.61%, clearly showing strength. However, over the past three months, Ameren's stock price has increased by 5.7%, outperforming Constellation's 1.9%, and its dividend yield of 2.82% is also more attractive. Both are representatives among top utility stocks, but their styles are completely different—one is a nuclear giant, the other a multi-energy portfolio.

Honestly, considering current valuation, Ameren's performance appears more balanced. Although both are actively expanding, Ameren is more aggressive in infrastructure investment (planning to invest $26.3 billion from 2025 to 2029), which is a good signal for long-term holders. Of course, the utility sector itself is defensive, and both companies are worth watching.

Recently, I’ve also been tracking energy-related assets on Gate. If you're interested in investment opportunities in power and clean energy, you can check out the relevant sectors on Gate. The story of nuclear energy is just beginning.
