Electric Source by Segment
Breaks down the sources of electricity generation, offering insight into the company’s energy mix, sustainability efforts, and potential regulatory impacts.Duke’s fleet mix is clearly shifting: coal’s role has become smaller and more volatile while natural gas volumes have grown and spiked in summer quarters, nuclear remains a stable baseload pillar, and renewables—though still a small slice—are steadily rising. Management’s $103B plan (including 5 GW gas and ~4.5 GW batteries) formalizes this transition and underpins the company’s earnings growth case, but amplifies execution, financing and fuel‑price exposure and timing risk tied to data‑center load ramp-ups.
