Constellation Energy Corporation (NASDAQ:CEG) is one of the utility stocks riding the 2026 “Reliability Shock.”

On April 21, 2026, Reuters reported that Constellation Energy Corporation (NASDAQ:CEG) is pursuing 1 gigawatt of nuclear uprates over the next decade, including 135 megawatts at the Braidwood and Byron Clean Energy Centers in Illinois. Reuters said the company is also prioritizing long-term contracts with hyperscalers to power AI data centers, a useful fit for a market where new firm electricity supply is becoming harder to secure quickly.

That follows a March 31 update in which Constellation said it planned $3.9 billion in capital spending and raised its share buyback authorization to $5 billion as it prepared for growing clean-power demand. Reuters also noted that Constellation had secured more than 5,650 megawatts of long-term clean-energy agreements, and agreements with Meta to keep an Illinois reactor operating for 20 years and with Microsoft to restart a reactor at the former Three Mile Island site in Pennsylvania.

The reliability angle is not frictionless, which actually sharpens the story. On April 6, Reuters reported that delays in transmission projects could slow the planned Three Mile Island restart, underscoring how AI-driven power demand is colliding with grid bottlenecks.

Constellation Energy Corporation (NASDAQ:CEG) is a Baltimore-based energy company with the largest nuclear fleet in the United States, as well as natural gas, geothermal, and other power assets.
