Electrical generation, transmission, and distribution

Overview

Electricity is generated at power plants and moves through a grid of substations, power lines, and distribution transformers before it reaches consumers. In the United States, the entire grid consists of more than 7,300 power plants, nearly 160,000 miles of high-voltage power lines, and millions of low-voltage power lines and distribution transformers connecting about 145 million customers.

Oregon OSHA’s Division 2/RR rules – which apply to general industry and construction employers – cover the operation and maintenance of electric power generation, control, transformation, transmission, and distribution lines and equipment. Construction work includes the erection of new electric transmission and distribution lines and equipment.
