Constellation Energy (CEG) is turning its nuclear fleet into something rare in the power business. It has locked in decades of demand ahead of time. On its latest earnings call, the company said most of its generation output is now contracted through 2050 and beyond. For a sector where revenue usually swings with volatile wholesale prices, that kind of visibility is almost unheard of. It also comes at a time when artificial intelligence is driving the steepest jump in electricity demand in a generation.
The second quarter showed the strategy in motion. Constellation signed 920 megawatts of new long-term nuclear power agreements. These contracts run 15 to 20 years and start delivering power between 2029 and 2032. Among them is a 176-megawatt Walmart (WMT) deal, split across two 15-year contracts, that will help fund an expansion at the Dresden plant in Illinois. These sit on top of earlier 20-year agreements with Microsoft (MSFT) and Meta (META), tying some of the world’s largest firms to Constellation’s output well into the 2040s.
