Pension funds, private equity and BlackRock-scale asset managers are taking America's monopoly utilities private — faster than ever, right as the AI boom guarantees their growth. Here's the map, the rate record, and what it has meant where it already happened.
Six states have a major electric utility owned outright by investment funds. Signed deals would add two more — and put both of New Mexico's biggest utilities under private capital at once.
Also in the picture: minority stakes — Blackstone owns 19.9% of Indiana's NIPSCO ($2.16B), GIC bought 19.9% of Duke Energy Indiana, Brookfield holds a stake in FirstEnergy's transmission arm. And New Mexico's largest gas utility sold to private-equity firm Bernhard Capital — closed August 12, 2026. Berkshire Hathaway's utilities (PacifiCorp, NV Energy) are private too, but under a strategic owner rather than a fund — a different animal, not mapped here.
Same measure for every utility: what an average home actually paid per kilowatt-hour, from federal filings. The gray dashed line is the U.S. average; the violet mark is the buyout.
The honest read: fund ownership hasn't meant one universal outcome. Puget — the longest experiment — went from costing half the U.S. average in the 1990s to crossing above it in 2025, with regulators approving back-to-back multiyear increases (+8.7% in 2023, +12% in 2025, +6.3% in 2026). Cleco, bought with $125M in customer credits attached, has tracked the national pace almost exactly. El Paso Electric is still below the national pace — its big increase landed in 2026, after this data ends.
And the control cases cut both ways: Minnesota Power's rates climbed 79% in the decade before its 2025 sale, and PNM's rose right at the national pace under public ownership. A 258-page George Mason University study of these same cases, written for Minnesota's Citizens Utility Board, lands on a sharp conclusion: what protects ratepayers is not who owns the utility but whether regulators enforce conditions — and whether the costs of serving giant new customers stay off household bills.
Average residential price, read the way the grid bills you — the dials alternate direction like the real instrument, and the register carries the exact digits. Disk speed is editorial: it tracks each line's climb since 2019, not live load. From the module's Instrument Shop.
A regulated utility earns a government-set profit on everything it builds. For decades, flat demand made that a sleepy business. The AI boom changed the math: data centers mean massive new construction — and every dollar of it earns the owner's return, approved by regulators, paid on monthly bills. Infrastructure funds noticed. The GMU study's first finding says it plainly: private capital now enters utilities for growth.
Analysts attribute ~63% of the 2025–26 jump — about $9.3 billion — to projected data-center growth. It reached bills fast: D.C.-area Pepco customers saw ~$21/month more starting June 2025. That's the cost story without any buyout — now layer the ownership question on top of it.
Blackstone's $11.5B deal for TXNM Energy — parent of PNM and Texas's TNMP — came with a move regulators had never blessed: Blackstone bought $400 million of TXNM stock at signing, before any approval.
July 2, 2026: New Mexico regulators ruled it illegal — and ordered it unwound at shareholder expense.
Hearing examiners recommended maximum penalties for "deliberate disregard" of the approval requirement. The acquisition case is frozen until the companies prove compliance — roughly September 2026 — pushing any decision deep into 2027 territory. Watchdogs point to Blackstone's NIPSCO stake as the template: buy in, then expand. New Mexico is the first state to make a fund walk one back.

Two buyouts in the 2000s, two in the 2010s — then $57B of deals in 24 months, plus a wave of minority stakes. The buyers changed too: from Macquarie's niche funds to BlackRock, Blackstone and sovereign wealth.
Cleco tracked the U.S. average; Puget nearly doubled it. The difference wasn't the owner's nationality or fee structure — it was what regulators approved, and what conditions they enforced. Ownership is the setup; enforcement is the outcome.
Funds are buying guaranteed returns on a construction boom. The GMU study's central ratepayer warning: the fight that matters is whether data-center infrastructure costs stay on data centers. That's the same firewall fight as El Paso's — now national.
Delisting ends SEC quarterly disclosure. What's left is what state commissions demand — which makes the NMPRC's July order, and conditions like Minnesota's rate freeze, the whole ballgame.
How we measured. Each series is total residential revenue ÷ residential kilowatt-hours sold from EIA Form 861 (2025 = early release), the same all-in measure used in File No. 1 — credits, fuel and riders included; delivery-only rows excluded from volumes. The U.S. line computed this way matches EIA's published averages within 0.04¢ in every overlapping year. Buyout-window changes compare the last full pre-buyout year to 2025 (Puget 2008→2025; Cleco 2015→2025; EPE 2019→2025), against the U.S. average over identical windows. One caution the source study stresses: rates rise for many reasons — fuel, storms, mandates, inflation — so trajectory is evidence, not verdict.
