Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Business and Organization | Business and Organization Powell Industries, Inc. (we, us, our, Powell or the Company) was incorporated in the state of Delaware in 2004 as a successor to a Nevada company incorporated in 1968. The Nevada company was the successor to a company founded by William E. Powell in 1947, which merged into the Company in 1977. Our major subsidiaries, all of which are wholly owned, include Powell Electrical Systems, Inc.; Powell (UK) Limited; Powell Canada Inc.; and Powell Industries International, B.V. We develop, design, manufacture and service custom-engineered equipment and systems which (1) distribute, control and monitor the flow of electrical energy and (2) provide protection to motors, transformers and other electrically powered equipment. Our principal products include integrated power control room substations (PCRs®), custom-engineered modules, electrical houses (E-Houses), traditional and arc-resistant distribution switchgear and control gear, medium-voltage circuit breakers, monitoring and control communications systems, motor control centers, switches and bus duct systems. These products are designed for application voltages ranging from 480 volts to 38,000 volts. Our products are used in the oil and gas markets, onshore and offshore production, liquefied natural gas (LNG) facilities and terminals, pipeline, refineries and petrochemical plants. Additionally, we manufacture products for the electric utility, light rail traction power as well as mining and metals, pulp and paper and other municipal, commercial and other industrial markets. Our product scope includes designs tested to meet both United States (U.S.) and international standards, under both the American National Standards Institute (ANSI) and International Electrotechnical Commission (IEC). We assist customers by providing field service inspection, installation, commissioning, modification, and repair services, as well as spare parts, retrofit and retrofill components for existing systems, and replacement circuit breakers for obsolete switchgear no longer produced by the original manufacturer. We seek to establish long-term relationships with the end users of our systems as well as design and construction engineering firms contracted by those end users. We believe that our culture of safety and focus on customer satisfaction, along with our financial strength, allow us to continue to capitalize on opportunities in the industries we serve.
