Purchase Report

Industry Summary

The 81,842 Electrical contractor firms in the US provide electrical installation, repair, and maintenance work. They handle wiring, lighting, networking, fire and safety equipment, and energy management systems, among other tasks. Much of the work is installation and repair of residential electrical wiring. Contractors must buy materials and then install them according to code in homes and other buildings.

Liability for Damages

Oftentimes builders or general contractors will try to cut corners, directing ECs to take shortcuts that violate code.

Demand Dependent on Construction Activity

Contractors can market new services such as design work during periods of low demand, but new construction ultimately drives the industry.


Recent Developments

Oct 9, 2025 - OpenAI, Partners to Spend $1 Trillion on Data Centers
  • In September, OpenAI announced $1 trillion in investments for building out data centers to power increasing global demand for its ChatGPT generative AI chatbot, according to The Wall Street Journal. OpenAI estimates it will need 20 gigawatts of computing power as the number of weekly global ChatGPT users has climbed to more than 700 million. At a cost of $50 billion per gigawatt, OpenAI, and its partners Oracle and Japan-based Softbank, will need to spend at least $1 trillion for computing infrastructure. In addition to a Central Park-sized computing warehouse complex under construction near Abilene, Texas, OpenAI is building a similar site in New Mexico with Oracle. Other, smaller complexes will be in Austin, Texas, and Lordstown, Ohio. Another site in an as-yet-unnamed location in the Midwest is also in the works.
  • New single-family home sales rose 20.5% month-over-month and 15.4% year-over-year in August 2025, according to the US Census Bureau. August’s new home sales reached 800,000 units, the highest number since January 2022. However, some economists told Reuters that the August new home sales numbers are probably inflated and may be revised downward later this year. Other housing bellwether metrics, including builder sentiment and job growth, don’t suggest a sudden surge in new home sales. However, falling interest rates could revitalize the sluggish housing market. The Federal Reserve cut its benchmark overnight interest rate from 4.25% to 4.0% on September 18 amid a tepid labor market, and the central bank is expected to announce more cuts before the end of the year.
  • Demand for building design services rose slightly in August from the prior month, but design demand remained in negative territory, according to a September report by the American Institute of Architects (AIA). The AIA’s Architecture Billing Index (ABI) rose to 47.2 compared to July’s reading of 46.2. Any reading of 50 or more indicates growth in architectural billings. The score for new project inquiries dropped to 50.3 in August from 53.4 in July, and the index for the value of new design contracts decreased from 47.9 to 47.2. August marked the 18th consecutive month of decline for new design contracts, the longest slump in the 15 years the AIA has collected data. However, the AIA’s Chief Economist, Kermit Baker said, "While business conditions remained soft at architecture firms nationally, there are signs that the downturn may be bottoming out. Inquiries for new projects have increased four straight months, and billings both at firms with a multifamily or commercial/industrial specialization are beginning to stabilize."
  • Renewable energy sources accounted for 91% of the 15 gigawatts (GW) of new electricity generation capacity that came online in the first five months of 2025, according to the Federal Energy Regulatory Commission (FERC) and reporting by Utility Dive. At 11.5 GW, solar held the largest share of new capacity additions, followed by wind (2.3 GW) and gas (1.3 GW). However, gas still accounts for the largest share of total electricity generation with 43%, followed by coal (15%), wind (11.8%), solar (11%), and nuclear (7.7%). Despite the Trump administration's favoring oil and gas and rescinding tax credits for renewables development and production, rising demand for electricity is expected to boost renewables. According to FERC, among 133 GW of “high probability” additions projected to be operational by 2028, 84% will come from solar and wind, and 15% from gas.
