Operators across the United States are pursuing power uprates at existing nuclear facilities to increase electricity generation. Recent federal funding and long-term corporate purchase agreements are driving multibillion-dollar investments to extract additional capacity from operating reactors.

These equipment upgrades allow plants to meet surging electricity demand from data centers and artificial intelligence expansion. While uprates provide a faster and less expensive alternative to constructing new facilities, the total potential capacity gains cover only a fraction of projected grid growth.

Upgrades could bring more clean power to the grid, but there's only so much room to grow.

In this age of rising electricity demand, people are trying to squeeze every last bit of power out of every power plant possible.

Over the past few weeks, there's been big news about nuclear power plants trying to do just that. Constellation, the largest nuclear operator in the US, announced plans to add nearly a gigawatt of new capacity across 11 existing nuclear reactors at six plants. And on October 5, the Department of Energy awarded a $4.2 billion loan to Vistra for previously announced upgrades at three plants.
