History and Development

Constellation Energy became an independent public company in 2022 following a spin-off from Exelon Corporation, which separated its power-generation business from regulated utility operations.

The separation allowed the company to focus exclusively on electricity generation and energy supply, particularly through its portfolio of carbon-free energy assets.

After the spin-off, Constellation strengthened its position in nuclear energy while expanding investments in renewable generation and emerging clean-energy technologies.

Today, Constellation Energy operates a large clean-energy fleet and focuses on supplying carbon-free electricity while developing new technologies related to energy storage, hydrogen, and decarbonization.
