Nuclear energy is becoming a more important source of reliable, clean power as countries strive to meet rising demand while cutting emissions. At the COP28 conference, the U.S., France, Japan, and the U.K. committed to tripling global nuclear capacity by 2050. This growing focus has positioned Cameco and Constellation as key players in different parts of the nuclear energy market. Investors are now looking for long-term opportunities in the sector, especially with recent market pullbacks.
Cameco: Uranium Miner with Cost Advantages
Cameco operates high-grade uranium mines in the Athabasca Basin in Canada, a region known for rich deposits. The company controls the McArthur River and Cigar Lake mines, which are among the lowest-cost producers in the world. These mines have life-of-mine cash operating costs of $21.72 and $23.94 per pound of uranium, respectively. This efficiency allows Cameco to generate a significant amount of uranium while minimizing environmental impact.
As countries seek to reduce reliance on Russian uranium, Canada and the U.S. need secure suppliers. Cameco serves both, avoiding the political and regulatory risks seen in uranium-rich regions such as Kazakhstan and Niger. This stability is a major advantage in a market that often faces volatility.
In addition to its uranium production, Cameco holds a 49% stake in Westinghouse Electric Company, a leading nuclear reactor builder. Westinghouse’s technology is used in half of the world’s operating reactors. With the U.S. Department of Energy backing $17.5 billion in loans for up to 10 Westinghouse AP1000 reactors, Cameco benefits from growth in reactor construction. On July 31, the company, along with Brookfield Renewable Partners, announced that Westinghouse had filed a draft registration statement for a potential IPO. This move could allow Cameco to raise capital and reduce debt while showing the market the potential value of its nuclear infrastructure assets.
Cameco also has long-term agreements to supply about 28 million pounds of uranium annually through 2030. This gives the company strong visibility into future revenue and production. With the stock down 31% from its 52-week high, investors are seeing it as a possible buying opportunity as the nuclear industry gains momentum.
Constellation: Top U.S. Nuclear Power Operator
Constellation Energy is the largest nuclear power operator in the United States. The company runs 14 nuclear generating stations with a total of 22 gigawatts of nuclear capacity. This accounts for around 10% of the country’s clean, carbon-free electricity supply. As energy demand grows, Constellation plays a crucial role in meeting the need for stable, reliable power.
The company’s high efficiency is one of its strongest assets. Last year, it achieved a nuclear capacity factor of 94.7%, meaning its reactors produced close to maximum output most of the time. This efficiency allows the company to generate steady revenue and ensure power is available during peak demand periods, when electricity prices often surge.
Constellation’s large nuclear footprint has attracted major tech companies. Microsoft, Meta Platforms, and CyrusOne have all signed long-term power purchase agreements with the company. On June 23, Constellation announced a new PPA with Walmart, marking the first such agreement for a major U.S. retailer. These partnerships highlight the growing demand for clean energy from large corporations.
In addition to these agreements, the company is investing in upgrades to its existing power plants to increase output. These improvements should enhance its position in the market as the push for carbon-free energy continues.
The U.S. Department of Energy has taken steps to support the development of next-generation nuclear technologies, including streamlined permitting and faster testing. These reforms are expected to speed up the commercial deployment of innovative reactor designs. Companies like Constellation and Cameco are well-positioned to benefit from this shift, as their operations align with the long-term goals of reducing emissions and ensuring a consistent power supply.
Investors are also taking note of the long-term potential of the nuclear energy sector. Recent price declines in Cameco’s stock, for instance, have sparked interest among those looking for undervalued opportunities in a market poised for growth. For companies like Constellation, partnerships with major tech firms signal a broader acceptance of nuclear energy as a key component of sustainable energy strategies.
With global commitments to expand nuclear capacity and a clear trend toward cleaner energy sources, the sector is expected to see steady investment and innovation over the next few decades. Cameco’s strong position in uranium production and its stake in Westinghouse provide exposure to both the raw materials and the infrastructure needed for new reactors. Meanwhile, Constellation’s expertise in operating efficient nuclear plants makes it a vital player in the U.S. energy landscape.
The nuclear energy industry is at an inflection point, driven by the need for low-carbon energy solutions and the push for energy security. As governments and businesses continue to invest in nuclear power, companies like Cameco and Constellation are likely to play a central role in shaping the future of the sector.
