Definition
Electricity, in legal contexts, is a commercially and industrially harnessed natural force — the controlled movement of charged particles through conductors — treated by law variously as a commodity, a utility service, a regulated product, and a subject of tortious harm. Law does not define electricity by its physics but by the legal relationships its generation, transmission, distribution, sale, and misuse create.
Four overlapping legal characterizations appear across the corpus:
1. Electricity as property or commodity. Courts and legislatures have long debated whether electricity is a "good" subject to property law, theft statutes, and commercial codes, or whether it is a service incapable of traditional ownership. The resolution varies by context: electricity is treated as property for purposes of theft and eminent domain, but UCC "goods" classification has been contested.
2. Electricity as a utility service. The dominant legal treatment. Electricity delivered through a grid is subject to pervasive federal and state regulation of rates, access, reliability, and market structure. The legal status of electricity as a regulated utility service is the framework within which most rights and obligations arise.
3. Electricity as a source of liability. Negligent handling, failure to maintain lines, and wrongful disconnection generate tort claims against utilities. The inherently dangerous character of electricity has led courts to impose strict or heightened-duty liability in some jurisdictions.
4. Electricity as a subject of tax and incentive law. Generation, sale, and consumption of electricity are points of taxation, and the transition to renewable sources has generated a substantial body of credit and incentive law at both federal and state levels.
Common Language
Modern common usage (Wiktionary): A phenomenon caused by the distribution and movement of charged subatomic particles and their interaction with the electromagnetic field; also, the supply of electrical power to a building or device.
Historical common usage (Webster's 1913): A power in nature exhibiting itself through circuit movement, polarity, attraction and repulsion, and chemical decompositions — understood as a fundamental physical force rather than a deliverable commodity.
The gap matters for researchers. Common usage treats electricity as a natural phenomenon or a household amenity. Legal usage treats it as a regulated commercial service with a specific delivery infrastructure, a set of federal and state regulatory regimes, defined market participants, and elaborate liability rules. The ordinary speaker who says the electricity "belongs" to the utility, or that a neighbor "stole" electricity, invokes concepts that have precise and sometimes counterintuitive legal content.
Recognized Forms
/SUBTYPES
Legal materials distinguish electricity primarily by its position in the supply chain and the regulatory regime that applies:
- Generated electricity: Subject to licensing, environmental permitting, and wholesale market rules (FERC jurisdiction under the Federal Power Act for interstate sales).
- Transmitted electricity: The high-voltage movement of power across the grid; subject to open-access tariff requirements and reliability standards (NERC, under FERC oversight).
- Distributed electricity: Local delivery to end users; primarily state public utility commission jurisdiction over rates and service obligations.
- Retail electricity: The sale to residential, commercial, and industrial customers; restructured in some states to allow competitive retail markets, monopoly in others.
- Renewable electricity: Generation from qualifying sources (solar, wind, hydro, geothermal); subject to distinct incentive structures, renewable portfolio standards, and tax credit regimes.
Why It Matters in Research
The central research trap is jurisdictional fragmentation. Federal jurisdiction (FERC) governs wholesale sales and interstate transmission; state public utility commissions govern retail rates and distribution. The boundary between these two has been actively litigated and has shifted over time, particularly following electricity market restructuring in the 1990s and 2000s. A researcher treating federal and state electricity law as a unified body will misread the sources.
Historical legal sources predate modern grid architecture entirely. Bouvier's entry reflects the late-nineteenth-century moment when electricity was a new industrial force, not yet the subject of the comprehensive regulatory edifice built after 1920 (Federal Water Power Act) and especially after 1935 (Federal Power Act, Public Utility Holding Company Act). Anderson's entry, routing readers to LIGHTNING, TELEGRAPH, and TELEPHONE, confirms that early legal treatment was organized around specific applications rather than electricity as a unified regulatory subject. Neither source is useful for understanding modern utility regulation, FERC market structure, or renewable energy law.
The "commodity vs. service" classification question has direct downstream consequences: it determines whether the UCC applies to an electricity supply contract, which theft statute governs unauthorized diversion, and how damages are calculated in commercial disputes. Researchers should not assume that a jurisdiction's answer in one context transfers to another.
Tax researchers face a rapidly changing landscape. Federal incentives for renewable electricity generation and electric vehicle charging have been substantially revised by the Inflation Reduction Act of 2022. Historical tax sources are of limited use for current law but remain relevant for understanding legacy credit structures and prior-period disputes.
Historical Dictionary Support
Bouvier's Law Dictionary offers the most substantive historical treatment, defining electricity as "a natural force utilized mainly for the production of heat, light, and power" and noting the "great increase in the use of this force and its application to the purposes of everyday life." This framing is historically significant: it captures electricity at the threshold moment when law was beginning to construct the regulatory and liability frameworks that would govern it for the next century. Bouvier signals awareness that existing legal categories were straining to accommodate the new technology but does not resolve the classification questions that courts would work through over subsequent decades.
Anderson's Dictionary of Law offers almost nothing: the entry consists entirely of cross-references to LIGHTNING, TELEGRAPH, and TELEPHONE. This tells the researcher something important — in Anderson's era, electricity had no unified legal identity. It was understood through its applications, not as a commodity or service in its own right. The modern unified regulatory treatment of "electricity" as a subject of law is a twentieth-century construction invisible to Anderson.
Neither historical dictionary anticipates the regulatory state that now governs electricity. Neither addresses FERC, public utility commissions, wholesale markets, open-access transmission, or renewable portfolio standards. Researchers using these sources for historical context will find them useful for the pre-regulatory period and for early tort and property questions; they are not a guide to the contemporary corpus.
Jurisdictional Note
Federal law (Federal Power Act, FERC regulations) governs wholesale electricity sales and interstate transmission. State public utility commissions govern retail rates, distribution, and service territory. Approximately half the states have restructured their retail electricity markets to allow competition; the remainder maintain traditional regulated monopoly structures. Researchers must identify which layer of the regulatory structure governs the transaction or dispute at issue before selecting applicable sources.
