Overview

Nuclear Power Generation covers electricity produced from nuclear fission — large baseload reactors providing carbon-free, around-the-clock power. At ~$35B it is a consolidated segment operated by a few large utilities and IPPs (Constellation, Vistra, Duke, Southern), supplying roughly a fifth of U.S. electricity and the largest source of carbon-free generation.

After years of pressure, nuclear is enjoying a renaissance: data-center and AI demand for firm clean power has driven hyperscalers to sign nuclear PPAs (and even restart retired plants), license extensions are keeping reactors running longer, and small modular reactors (SMRs) promise new build. It is consolidated, capital-intensive, and strategically central to firm, carbon-free power.
