Electric Power Transmission, Control & Distribution in the US: Market Size, Businesses & Forecast 2026

The Electric Power Transmission, Control & Distribution industry in the US manages the critical bulk transport and localized retail delivery of electrical energy from generation facilities to end consumers. Spurred by the rapid expansion of energy-intensive AI data centers and strategic manufacturing reshoring, the industry is transitioning from a multidecade era of flat electricity demand to a period of accelerated growth, with national 5-year load growth forecasts nearly doubling from 2.6% to 4.7% in 2023 filings (Federal Energy Regulatory Commission / Grid Strategies). This surge is driving substantial grid modernization investments, with annual investor-owned utility capital expenditures

What does the Electric Power Transmission, Control & Distribution in the US industry cover?

This industry comprises establishments primarily engaged in the operating of electric power transmission systems, controlling the routing of electricity across regional grids, and distributing power through localized networks to end-users. Transmission utilizes high-voltage lines (typically 110 kV or higher) to move bulk electricity over long distances, while distribution networks step down voltage at substations for retail customer delivery. The industry also encompasses grid control operations, balancing authorities, and the maintenance of physical substations, power poles, and smart meters.

• •Covers NAICS code 22112, which specifically isolates electric power transmission, control, and distribution from electricity generation.
• •Encompasses both high-voltage bulk transmission lines and local radial or interconnected distribution networks.
• •Includes the physical operations of substations, line maintenance, and grid balancing services managed by regional organizations.

Who operates in the industry and how is it structured?

The US electric grid is operated through a complex mix of private and public entities structured around regional reliability networks. Retail electricity delivery is dominated by large Investor-Owned Utilities (IOUs), which operate as regulated regional monopolies and serve approximately 62% of US electricity customers (University of Michigan STPP, 2026). The remaining customer base is served by publicly owned municipal utilities (POUs) and customer-owned rural electric cooperatives.

• •Investor-owned utilities (IOUs) serve approximately 62% of all US electricity customers as of 2024.
• •Publicly owned utilities (POUs) represent 55% of all individual utility companies despite serving only 13% of customers.
• •Bulk transmission flows are managed across regional seams by Independent System Operators (ISOs) and Regional Transmission Organizations (RTOs) like PJM Interconnection, MISO, and ERCOT.

What drives demand in the industry?

The principal driver of industry activity is the volume and peak capacity requirements of residential, commercial, and industrial electricity consumption. After decades of stagnant load growth averaging below 1% annually, demand is surging due to the explosive construction of artificial intelligence data centers, advanced semiconductor fabrication facilities, and domestic electric vehicle supply chain manufacturing. This rapid load expansion requires significant, immediate investments in both physical grid connections and interregional transfer capacity.

• •National 5-year electricity demand forecasts grew from a projected 2.6% to 4.7% in 2023 FERC filings, representing 38 GW of new expected peak demand.
• •Data center power consumption reached 176 TWh by 2023, representing 4.4% of total US electricity consumption, driven by high-density GPU acceleration (Lawrence Berkeley National Laboratory).
• •Industrial reshoring and clean energy manufacturing commitments in the US exceeded $481 billion between 2021 and late 2023.

Who are the notable companies in the industry?

Because transmission and distribution operate as natural monopolies within designated geographic service territories, companies do not compete directly for retail customers. Instead, they compete for regulatory capital allocation and rate-of-return approvals from state public utility commissions. Large, multi-state holding companies dominate the private-sector landscape, deploying billions in capital expenditure to expand their regulated asset bases.

• •Duke Energy Corporation operates major regulated transmission and distribution networks across multiple states including North Carolina, South Carolina, Florida, and Indiana.
• •Southern Company manages expansive utility networks across the Southeast, notably through its subsidiary Georgia Power, which is facing rapid load growth.
• •American Electric Power Company (AEP) operates one of the nation's largest transmission networks, spanning 40,000 miles across 11 states.
• •NextEra Energy, Inc. operates Florida Power & Light Company (FPL), the largest vertically integrated rate-regulated electric utility in the US.

What are the recent trends and outlook?

The industry is undergoing an unprecedented capital deployment cycle aimed at integrating remote utility-scale renewable generation and hardening infrastructure against extreme weather. Grid operators are increasingly deploying Grid-Enhancing Technologies (GETs), such as dynamic line ratings and advanced power flow controllers, to optimize existing pathways amid long interconnection queues. However, physical transmission line construction remains a bottleneck, with the US building only 55 miles of high-capacity lines (345 kV and above) in 2023.

• •Planned transmission expansion capital investments by major utilities increased to $15.1 billion for 2024, compared to $9.2 billion in 2022.
• •Annual investor-owned utility generation and grid capital expenditures increased 22% in inflation-adjusted terms in 2025 alone (Columbia University CGEP, 2026).
• •Regulators faced an unprecedented volume of rate increase requests from IOUs, totaling $18 billion in filings during 2025.

How is the industry regulated?

Operating companies are subject to overlapping federal and state regulatory frameworks that govern retail rates, safety standards, and regional grid planning. At the federal level, the Federal Energy Regulatory Commission (FERC) regulates interstate transmission rates and wholesale electricity markets, while state Public Utility Commissions (PUCs) set retail rates using cost-of-service models. Compliance is heavily driven by reliability standards enforced by the North American Electric Reliability Corporation (NERC) and new federal directives designed to streamline long-term transmission planning.

• •FERC Order 1920, issued in 2024, mandates that transmission operators engage in 20-year, long-term forward-looking transmission planning.
• •State Public Utility Commissions approved an average of 66% of the record-high utility rate increase requests filed in 2025.
• •Reliability and transfer capabilities are governed by NERC standards, which increasingly focus on interregional transfer capacity during extreme winter and summer weather events.
