Nuclear Plant Restart Delayed to 2031
27 Mar
Summary
- Former nuclear plant's grid connection now slated for 2031.
- Restart aims to power Microsoft data centers with clean energy.
- Transmission upgrades are causing the unexpected four-year delay.
The PJM grid operator has informed Constellation Energy that the former Three Mile Island nuclear plant in Pennsylvania, being repurposed as the Crane Clean Energy Center, will likely not connect to the grid until 2031. This represents a four-year delay from the original schedule. Constellation is working diligently to have the plant ready to produce electricity by its initial goal of 2027. The company is actively engaged with PJM and transmission owners to accelerate the grid connection timeline.
This delay stems from necessary transmission upgrades identified by PJM. Constellation aims to overcome these hurdles to supply electricity to Microsoft's data centers. This endeavor marks a significant effort to restart a fully shut nuclear power plant, a feat not previously accomplished. The rising demand from tech companies and electrification initiatives is driving such efforts across the U.S.
