American households served by investor-owned utilities now pay 17.8 cents per kilowatt-hour — 23% more than the 14.5 cents at public utilities and 26% more than the 14.1 cents at co-ops. The premium is not new, but it is accelerating. Since 2020, investor-owned prices rose 34%, public prices rose 19%, and general inflation ran 24%. The shareholder model did not merely track the energy crisis — it amplified it. The gap opened almost entirely during the 2020-2023 energy price spike. Investor-owned utilities jacked prices 25% during that window; public utilities and co-ops managed 11%. Before and after the spike, both ownership types rose at roughly the same pace. The crisis functioned as a ratchet: prices went up together, but investor-owned prices never came back down to the prior spread. After adjusting for inflation, investor-owned prices rose 7.9% in real terms. Public and co-op prices actually fell 4.3%. The geographic spread is dramatic. Maine, Washington, California, New Jersey, and New York show the widest gap between investor-owned and nonprofit price growth. New York State Electric & Gas leads the pack with a 97% price increase since 2020 — nearly doubling bills in five years. San Diego Gas & Electric (+79%), Southern California Edison (+73%), and Central Maine Power (+69%) are close behind. In only 10 states did nonprofit prices rise as fast or faster than investor-owned ones. Structural advantages for public utilities are real: no income tax, tax-exempt borrowing, and access to cheap federal hydropower. These factors explain part of the level difference. They do not explain why the gap widened after 2020. The widening is a behavioral story — how different ownership structures respond to cost shocks. Investor-owned utilities operate under a regulated-return model that incentivizes capital spending (earning a return on what they build) and creates institutional pressure to pass input costs through quickly and completely. The distribution data sharpens the picture. Among investor-owned utility customers, 67% pay 12-20 cents per kWh, and 11% pay 30 cents or more. Among co-op customers, 52% pay under 14 cents. Among public utility customers, 61% pay under 14 cents, with a notable bump at the high end driven by LADWP and Long Island Power Authority, which together account for 13% of public-utility homes. Co-ops have the lowest per-kWh prices but the highest monthly bills ($159 average), because their customers — typically rural — consume more power. The EIA data captures what homes actually paid divided by kilowatt-hours consumed, not the rate-case mechanics behind pricing. That distinction matters: the data shows outcomes, not intent. But outcomes are what hit household budgets, and the outcome is clear. Investor-owned utilities extracted more value per unit of electricity during the crisis and kept the spread afterward. The 39-of-48-states pattern — investor-owned charging more within the same state — controls for the cheap-hydro objection. This is not just geography; it is ownership structure producing different price outcomes from the same wholesale market. If retail suppliers serving homes on investor-owned lines are included, the price increase since 2020 climbs to 36%. The deregulated retail layer adds another intermediary capturing margin. Every link in the chain between generation and the meter is an opportunity for extraction, and investor-owned structures have more links.
