Regulation and Administration of Communications, Electric, Gas, and Other Utilities (NAICS 926130)

A Histometrics industry primer for public-market and private investors.

---

1. Overview

NAICS 926130 is not an industry you can buy. The North American Industry Classification System (NAICS, the U.S. government's standard code for industries) uses it for the government side of utility markets — the federal and state bodies that license, inspect, rate-set, and write the rules for electric power, natural gas, water, sewerage, and communications providers. NAICS files it under Sector 92, Public Administration. Every "establishment" in the code is a public body: the Federal Energy Regulatory Commission (FERC), the Federal Communications Commission (FCC), and the roughly 50 state public utility commissions (PUCs), also called public service commissions (PSCs).[1][14]

So why would an investor read a primer on a government function? Because these agencies write the economics of some of the largest, most widely owned assets in the country. A regulated electric, gas, or water utility earns essentially the return a commission allows it to earn on the capital it invests. A telecom carrier's spectrum, fees, and merger approvals run through the FCC. An interstate gas pipeline's tariffs are set at FERC. The regulator is the single biggest swing factor in whether a utility investment compounds steadily or stalls. Understanding the regulator is how you underwrite the regulated.

There is no direct stake to take in a regulatory commission — it is government, largely funded by the industries it oversees. Exposure is always indirect: public investors buy the regulated utilities, communications carriers, tower and fiber owners, and water companies these agencies govern (equities and bonds); private investors reach the same cash flows through infrastructure funds, project finance, private utility acquisitions, and utility-related debt. Sections 4 and 10 lay out those routes.

2. What it is, and what it excludes

In scope. Per the Census Bureau definition, 926130 comprises government establishments primarily engaged in the administration, regulation, licensing, and inspection of utilities — communications, electric power (including fossil, nuclear, solar, water, and wind), gas, water supply, and sewerage.[1][2] Concretely, that covers:

• Federal energy and communications regulators — FERC (interstate wholesale electricity, interstate gas pipelines, hydropower licenses, liquefied natural gas [LNG] terminals) and the FCC (spectrum, interstate and international communications, broadband).[6][8]
• State public utility / public service commissions — the bodies that set retail rates and service rules for investor-owned electric, gas, water, and (residually) telephone utilities in each state.[14]
• Nuclear safety regulation of power reactors, whose licensing-and-inspection function fits the code's "electric power (including … nuclear)" language — carried out federally by the Nuclear Regulatory Commission (NRC).[1][11]
• Administration of irrigation and public utility districts.[2]

What it is NOT (adjacent codes to keep straight). The distinction that matters most: this code is the referee, not the player.

• The utilities themselves sit in Sector 22 (Utilities) — electric power generation/transmission/distribution (2211), natural gas distribution (2212), water, sewer, and steam (2213). Government establishments that operate utilities are classified there too, not here.
• Telecom and internet carriers are in Sector 517 (Telecommunications); lessors of telecommunications structures (e.g., towers) fall in NAICS 531190.
• 926110 — Administration of General Economic Programs; 926120 — Regulation of Transportation Programs; 926140 — Regulation of Agricultural Marketing; 926150 — Regulation of Miscellaneous Commercial Sectors. Utility regulation is deliberately carved into its own 926130.[2]
• Environmental regulation of air, water, and waste (the Environmental Protection Agency, EPA) sits in 924110, not here — even though environmental rules bear heavily on power plants and water systems.

Ownership mix. The code itself is 100% government — no shares, no private owners, no profit motive inside it. The operating market it regulates has a mixed ownership structure. In reported U.S. retail electricity sales, investor-owned utilities (IOUs) accounted for about 57%, public and federal entities 16%, electric cooperatives 13%, and other providers 15% in the cited year.[25] Water is more fragmented and more government-dominated: Essential Utilities' filings describe roughly 50,000 U.S. community water systems, about 81% serving fewer than 3,300 customers, with most systems — and much of the population served — government-owned.[31]

3. How big it is

Ground-truth caveat first. Histometrics has no ingested federal business-statistics metrics for NAICS 926130 — and that absence is itself the story, not a data gap to paper over. The Census Bureau's County Business Patterns and the Economic Census, the usual sources for establishment counts, payroll, and receipts, exclude Sector 92 (Public Administration) because these are government bodies, not businesses.[3] The Small Business Administration's size standards likewise do not apply — there are no "small businesses" in this code. Even where public-administration units do appear in labor data, the Bureau of Labor Statistics (BLS) notes that public-administration classifications are verified less frequently than most private establishments.[4] So the standard business-statistics picture of 926130 is essentially blank by design, and missing data is not zero — any figure claiming otherwise should be treated with suspicion.

What can be measured comes from agency budgets and government-employment counts, not business surveys. Assembled agency by agency (each figure cited), the workforce is on the order of tens of thousands of people nationwide:

(FTE = full-time equivalent staff.) Across the states, the trade group NARUC (National Association of Regulatory Utility Commissioners) represents all 50 states plus the District of Columbia, Puerto Rico, and the Virgin Islands.[15] S&P Global's regulatory-research unit tracks 54 commissions with 216 commissioner seats, of which roughly 210 were filled in 2025.[14]

Perspective. The headcount here is small; the dollars it governs are enormous. For scale, the U.S. system these bodies oversee produced about 4,178 billion kilowatt-hours of utility-scale electricity and recorded about 3,861 billion kilowatt-hours of retail sales in 2023.[25] A single mid-size state commission of a few hundred staff sets the returns on tens of billions of dollars of utility assets — the most leveraged headcount in the utility value chain.

4. The investable universe

Direct plays: none. You cannot buy FERC, the FCC, the NRC, or a state PUC. This is the cleanest example in the Histometrics series of a code with zero investable entities inside it. The names below are adjacent proxies — the regulated companies whose economics these agencies define. (Tickers and valuation belong to this section, not the prose above; scale is illustrative and moves daily.)

Company disclosures confirm the regulated exposure of NextEra, Duke, Exelon, American Water, Southern, AEP, Dominion, and American Tower.[32][33][34][35][36][37][38][39] Which regulator matters depends on the asset: Florida PSC and FERC for NextEra; the Georgia/Alabama/Mississippi commissions plus FERC for Southern; the Virginia SCC plus FERC for Dominion; a dozen-plus state PUCs plus FERC for AEP; the California PUC plus FERC for Sempra/PG&E; state PUCs for American Water; FERC tariffs for interstate pipelines (Kinder Morgan, Williams); and the FCC for Verizon, AT&T, and T-Mobile.

Major non-investable owners. A large share of U.S. utility service is delivered by entities outside both 926130 and the stock market: municipal utilities (city-owned power/water), public power authorities (e.g., the Tennessee Valley Authority), and rural electric cooperatives (member-owned). These are regulated more lightly or self-governed and cannot be bought as equities — though their bonds trade.

Major private-market owners and platforms include:

• Berkshire Hathaway Energy, a subsidiary of Berkshire Hathaway, holding regulated utilities, gas pipelines, transmission, and renewables.[40]
• LS Power, a private owner/developer of generation and transmission assets.[41]
• Stonepeak, invested across broadband, fiber, wireless infrastructure, generation, and transmission.[42]
• Brookfield infrastructure funds, including a minority investment in Duke Energy Florida and U.S. fiber assets.[43]
• BlackRock's Global Infrastructure Partners (GIP), which invests across power, renewables, digital infrastructure, and water — and in 2026 led, with EQT, a consortium acquiring merchant/renewable generator AES.[44]

5. How the money works

This code has two money stories: how the agencies fund themselves, and how their decisions mint (or destroy) returns for the regulated companies — the part investors care about.

A) The agencies: cost-recovery, not profit. The striking feature of U.S. utility regulation is that the regulators are largely paid for by the regulated. FERC recovers 100% of its appropriation through annual charges and filing fees on the pipelines and power markets it oversees, depositing the money to the Treasury as a direct offset — net cost to the taxpayer is essentially zero.[5] The FCC has been funded 100% by regulatory fees on license holders since 2009.[8] The NRC recovers roughly 90–100% of its budget from nuclear licensees.[13] State commissions run on assessments levied on the utilities in their state. Practically, the industry pays for its own oversight — which is why agency budgets track workload, not tax politics.

B) The regulated companies: rate base × allowed return. This is where investor dollars are made, and it is the mechanism this whole code administers. A traditional regulated utility earns money like this:[16]

1. It invests capital — poles, wires, pipes, substations, meters, treatment plants, power plants. The depreciated value of that prudently-invested capital is its rate base.
2. In a rate case, the commission sets a revenue requirement covering the utility's operating and maintenance costs, depreciation, and taxes, plus an allowed return on equity (ROE) — the profit rate the utility may earn on the equity portion of that rate base. In 2024–25, U.S. commissions authorized electric-utility ROEs averaging roughly 9.5–9.7%.[21]
3. Rates (customer bills) are then set to collect that requirement.

So a utility's earnings grow chiefly by growing rate base — investing more capital the commission agrees customers should pay for. U.S. electric and gas utility capital spending was projected around $215 billion in 2025, up sharply from about $173 billion in 2024,[22] and S&P Global forecasts near $1.3 trillion cumulatively over 2026–2030;[23] the Edison Electric Institute (EEI, the IOU trade group) counts more than $1.1 trillion planned by investor-owned utilities alone across 2025–2029.[24] Each of those dollars only earns a return if a regulator in this code approves its recovery. That is the crux: the commission converts capital spending into shareholder return — or refuses to.

For the investor, the numbers to watch are therefore regulatory: the authorized ROE, the equity layer allowed in the capital structure, how much of proposed capex the commission approves, whether costs are recovered promptly (via trackers and forward-looking "future test years") or lag for years, and the regulatory lag / earned-vs-allowed gap — how far below the allowed ROE a utility actually earns. A "constructive" commission can be worth a full valuation multiple versus a hostile one.

Different mechanics next door. Not everything in the adjacent universe is a rate-base network. Merchant generators earn from wholesale energy, capacity, ancillary services, and power purchase agreements (PPAs), with more exposure to fuel prices, weather, congestion, and market prices; regional transmission organizations (RTOs) and independent system operators (ISOs) run many of those wholesale markets under FERC.[6] Communications carriers earn subscription revenue; tower and fiber owners earn recurring lease revenue — watched via subscribers, average revenue per user (ARPU), churn, tenancy, and utilization. Water and wastewater cash flow turns on customer connections, approved rates, usage, compliance spending, and system acquisitions. In every case the regulator's ruling — not a purely competitive market — sets the ceiling on returns.

6. What drives demand

"Demand" here means demand for regulatory activity — how busy and consequential these agencies become — driven by the same forces reshaping energy and communications.

Reported facts. The U.S. Department of Energy (DOE) reported that data-center electricity use rose from 58 terawatt-hours (TWh) in 2014 to 176 TWh in 2023, and could reach 325–580 TWh by 2028 — about 4.4% of U.S. electricity in 2023, rising to a projected 6.7%–12% share by 2028.[26] The U.S. Energy Information Administration (EIA) forecasts U.S. electricity load growth of 1.9% in 2026 and 2.5% in 2027, driven partly by data centers and industrial demand.[27] After roughly two flat decades, that is a step-change that forces new generation, transmission, and interconnection decisions through FERC and the states.

Other drivers:

• The capital super-cycle. Record utility capex (Section 5) means record rate-case volume and bigger dockets — every major investment eventually lands on a commission's desk.[22]
• Electrification of transport, buildings, and industry, plus manufacturing reshoring and new industrial loads.
• The energy transition. Renewables, storage, and transmission have swamped generator interconnection queues at FERC and grid operators — a backlog that is itself a regulatory bottleneck investors watch closely.
• Broadband and spectrum. Federal broadband subsidies and the fight over 5G/6G and satellite spectrum keep the FCC's docket full and directly affect carrier economics.
• Water quality and aging pipes. Drinking-water standards, wastewater treatment, drought resilience, and pipe replacement.
• Safety shocks. Wildfires linked to power lines and gas-pipeline explosions trigger new oversight, cost disallowances, and liability.
• Affordability politics. Rising customer bills draw legislative and public pressure that flows straight into commission decisions on how much utilities may charge and earn.

Forward-looking judgment. The strongest near-term opportunity is likely in transmission, distribution, grid modernization, and selected regulated utilities. Demand growth should help asset owners — but the benefit depends on permitting, interconnection, customer affordability, and regulators' willingness to approve recovery.

7. Regulation (the product itself)

For most industries, regulation is a constraint. Here it is the output.

Key structural features:

• Federal statutes. The Federal Power Act and Natural Gas Act give FERC authority over interstate power and gas;[6] the Communications Act underpins the FCC;[8] the Atomic Energy Act and the Nuclear Energy Innovation and Modernization Act (NEIMA) govern the NRC.[13]
• The federal–state split is the defining feature. FERC regulates interstate wholesale transactions, transmission, and pipelines; state commissions regulate retail rates, local distribution, and the siting of most in-state infrastructure. The seam between them — transmission cost allocation, how state clean-energy policy interacts with federal markets — is a perpetual battleground, and jurisdictional overlap makes approval timelines a material investment variable.[28]
• Commissioner selection. Most state commissioners are appointed by the governor or legislature, but in 11 states they are elected by voters — a fact with real investment consequences, because elected commissions can be more responsive to bill-payer anger and less predictable on ROE.[14] Federal commissioners (FERC, FCC, NRC) are presidentially appointed and Senate-confirmed, with fixed terms and party-balance limits, so their composition is sensitive to the political cycle.
• Regulatory models vary by state. Some keep vertically integrated, cost-of-service utilities; others restructured in the late 1990s–2000s into competitive wholesale markets and retail choice; a growing number are experimenting with performance-based regulation (linking allowed returns to outcomes rather than pure spending).

---

8. Competitive dynamics and consolidation

There is no "competition" among regulators — each is a legal monopoly over its territory. But the landscape moves.

Electric and gas distribution networks are usually local natural monopolies, because duplicating pipes and wires is uneconomic. Competition is stronger in power generation, wholesale markets, broadband, wireless service, tower leasing, and infrastructure development. Barriers to entry are steep: rights-of-way and permitting, spectrum and network density, grid interconnection, environmental and safety approvals, heavy capital needs, reliability obligations, and entrenched service territories.

• Consolidation of the regulated increases regulatory complexity. As holding companies acquire across state lines, one corporate parent answers to a dozen commissions plus FERC, and every deal needs multi-jurisdiction, public-interest review — often conditioned on ratepayer benefits.[28] Recent transactions show the pattern: Brookfield agreed in August 2025 to buy a 19.7% minority interest in Duke Energy Florida for $6 billion (Duke keeps control and operations);[43] American Water and Essential Utilities announced an all-stock merger in October 2025 to form a leading regulated water/wastewater utility serving more than 4.7 million connections, targeting a close around early 2027 subject to state approvals;[35][45] and a GIP/EQT-led consortium agreed to acquire AES in a deal valued at about $33.4 billion including debt, approved by AES stockholders in mid-2026.[44]
• Regional grid operators (RTOs/ISOs) sit alongside this code — FERC-regulated but not part of 926130 — and their expansion shifts authority upward toward the federal level.
• Federal–state tension intensifies with the energy transition, as national goals (transmission, interconnection reform) collide with state control over siting and resource choices.
• Capacity and capture. A chronic concern is that agencies are under-staffed for the workload (interconnection backlogs are the poster child), alongside the perennial worry of regulatory capture — commissions growing too close to the utilities they oversee. Both feed how sophisticated investors handicap a state's "regulatory quality."

9. Risks (from the investor's seat)

Because you invest around this code rather than in it, the risks are the ways regulatory decisions and physical events can impair the regulated companies:

• Adverse rate outcomes. A low authorized ROE, a thin equity layer, or disallowed capital costs cut earnings directly — the number-one risk in regulated-utility investing.
• Regulatory lag. Slow dockets and historical test years let costs run ahead of recovery, so utilities earn well below their allowed return.
• Affordability & political risk. Bill backlash — and, in 11 states, directly elected commissioners — makes outcomes less predictable and occasionally punitive.
• Federal-appointment swings. Changes in FERC/FCC/NRC composition can reverse policy on transmission, mergers, spectrum, or market rules within a single administration.
• Construction & financing risk. Transmission, nuclear, generation, water, and broadband projects face cost overruns and long permitting timelines; heavy capital needs make debt costs, equity issuance, and credit ratings pivotal.
• Catastrophe & cost-disallowance. Wildfires, storms, floods, drought, and contamination can lead commissions to deny recovery of billions in costs (a live risk for several Western and California utilities), and can create large liabilities. Cyberattacks add to the tail.
• Commodity & market risk. Merchant power and gas businesses stay exposed to fuel prices, weather, congestion, and wholesale prices; communications assets can face obsolescence and price competition.
• Agency capacity. Interconnection and permitting backlogs — plus hiring freezes or budget fights at the agencies themselves — delay the projects that drive rate-base growth.
• Private-market risk. Direct infrastructure investments are illiquid, highly negotiated, and often leveraged.

Note the asymmetry: the same regulatory power that caps returns also guarantees them. A constructive commission gives regulated utilities unusually stable, bond-like cash flows — which is precisely why they attract conservative and income investors.

10. How to invest, and the outlook

You can't own the regulator — you own what it regulates. Practical routes:

• Public equities. Regulated electric, gas, and water utilities (Section 4); communications carriers under the FCC; interstate pipeline companies under FERC. Typically lower-beta, dividend-paying stocks whose appeal is stability, not growth spurts. Separate regulated from unregulated earnings, wires-and-pipes from commodity generation, approved capital from speculative plans, and constructive regulation from contested cases.
• Utility bonds. Investment-grade debt of regulated utilities, backed by commission-set rates — a core fixed-income holding.
• Sector funds / ETFs. Broad utility-sector index funds bundle dozens of regulated names for exposure without single-state regulatory bets.
• Private markets. Infrastructure, energy-transition, and digital-infrastructure funds buy regulated utilities, transmission, pipelines, contracted renewables, towers, and fiber outright — plus project finance, private credit, co-investments, and municipal utility revenue bonds for the non-investor-owned slice.

The operating metrics that matter across these routes are the same ones the commissions drive: rate-base growth, allowed ROE, regulatory lag, load growth, outage performance, fuel-cost recovery, water-system compliance, non-revenue water, subscriber growth, ARPU, churn, and tower/fiber utilization. Valuation multiples, dividend yields, and share prices belong in this company-selection step — not in the definition of 926130.

Near-term outlook. The central tension for the next several years is straightforward: unprecedented capital needs meeting the willingness of regulators to fund them. Data-center and AI load growth, electrification, grid modernization, and transmission buildout point to a multi-year rate-base expansion — bullish for regulated companies if commissions in this code grant timely, adequate cost recovery. Working against that, rising customer bills are colliding with affordability politics that can pressure allowed returns downward. The code itself will never become a standalone investable sector — it is government administration, not corporate production. But its importance should only rise. The most attractive adjacent opportunities look like regulated networks, transmission, selected water platforms, and communications infrastructure; merchant generation and private utility acquisitions may offer higher growth with greater market, construction, regulatory, and financing risk. The single most useful question when underwriting any of them stays the same: what will its commission let it earn?
