Constellation Energy runs a 55-gigawatt portfolio of nuclear, gas, geothermal, hydro, wind and solar plants, supplying electricity and natural gas to commercial and retail customers across the US.
Constellation Energy operates the kind of infrastructure that makes security a first-order engineering problem rather than a compliance afterthought. The company is the largest producer of clean, low-carbon and reliable energy in the United States and the largest private-sector power producer in the world, with an integrated portfolio of nuclear, natural gas, geothermal, hydroelectric, wind and solar facilities. Total generating capacity stands at 55 gigawatts - enough, on its own framing, to power roughly 27 million homes. Headquartered in Baltimore, Maryland, Constellation supplies electricity and natural gas through commercial and retail energy businesses across the United States.
The threat model follows the asset base. Nuclear power generation, grid reliability, and a mix of hydro, wind and solar mean the technical surface spans generation control, operational technology, and the commercial systems that move energy to customers. Domains in active scope include nuclear license renewal, clean-energy innovation, and the ongoing integration of a portfolio expanded by the combination with Calpine. Constellation's stated commitments - nuclear preservation, engagement in public policy, and dependable energy for a growing economy - place it squarely in critical infrastructure work where availability and integrity are non-negotiable.
Roles here touch an operating fleet, not a slide deck: the technical domains range across nuclear, natural gas, geothermal, hydroelectric, wind and solar generation, plus the grid-reliability and clean-energy innovation work that ties them together. For security practitioners, that means the environment is a hybrid of generation, energy supply, and utility-scale operations, with the physical and cyber systems tightly coupled.
