With the formal establishment of Westinghouse Electric Company in 1886, the nascent enterprise immediately confronted the entrenched interests of direct current (DC) proponents, most notably Thomas Edison and the companies bearing his name. This struggle, often dramatized as the "War of the Currents," was a fundamental challenge to Westinghouse's market strategy and the broader electrification of America. The company positioned itself as the leading advocate for alternating current (AC), emphasizing its superior efficiency for long-distance power transmission and its adaptability for diverse applications. AC's key advantage lay in its ability to easily transform voltage, allowing for efficient transmission at high voltages over significant distances and then stepping down the voltage for safe, local distribution. In contrast, DC systems suffered from severe voltage drop over distance, requiring numerous, closely spaced generating stations to serve even moderate areas. Westinghouse's early operations focused intensely on developing and refining AC generators, transformers, and motors, aiming to build a complete and reliable system that could demonstrably outperform DC alternatives. Initial customers included utilities and municipalities seeking more expansive and economical lighting and power distribution solutions beyond the limited reach of existing DC grids, which primarily served dense urban centers.
The first significant product offerings from Westinghouse included AC generators and incandescent lamps, which were crucial for establishing a foothold in the competitive lighting market. The company quickly moved to demonstrate the practical advantages of its AC system through early installations. In 1886, Westinghouse installed one of the nation's earliest commercial AC systems in Buffalo, New York, followed swiftly by installations in other cities like Great Barrington, Massachusetts, and Greensburg, Pennsylvania. The Great Barrington system, for instance, employed a 500-volt primary circuit and a 100-volt secondary circuit to illuminate local businesses and homes, concretely demonstrating the viability of voltage transformation and distributed AC power. These early projects, while modest in scale compared to later undertakings, served as vital proofs-of-concept for AC's reliability and efficiency. To compete directly in the critical incandescent lighting segment and bypass Edison's patents, which primarily covered the high-resistance carbon filament and the vacuum bulb, the company also introduced the "stopper" lamp. This improved incandescent bulb design featured a unique threaded brass base that sealed the bulb, allowing the glass bulb to be manufactured separately from the filament and base assembly, thereby providing a complete and legally distinct lighting solution.
Funding for Westinghouse Electric was initially sourced from George Westinghouse's personal wealth and the capital generated by his other successful companies, primarily Westinghouse Air Brake. However, the rapid expansion inherent in pioneering a new electrical system required significant further investment. The company conducted several funding rounds in its early years, attracting investors who were convinced by the technical merits of AC and Westinghouse's entrepreneurial vision. Financial challenges were a constant companion during this period, particularly as the company invested heavily in research, development, the establishment of manufacturing facilities, and the acquisition of critical patents. A pivotal strategic move was the acquisition of Nikola Tesla’s patents for polyphase AC motors and power transmission in 1888. This agreement, which reportedly involved an initial payment of $25,000, a royalty of $2.50 per horsepower of motors sold, and later a buyout of all remaining royalty rights for $216,600, provided Westinghouse with intellectual property that was essential for developing a comprehensive and robust AC system. Tesla's polyphase system, particularly his induction motor, was revolutionary because it offered greater efficiency and smoother operation compared to single-phase AC or DC motors, making AC truly viable for heavy industrial power applications beyond mere lighting.
Building the team was another critical aspect of the founding phase, as Westinghouse recognized the need for exceptional engineering talent. George Westinghouse surrounded himself with a cadre of brilliant engineers and scientists, including William Stanley Jr., whose refinement of the practical, efficient shunt-wound transformer in 1886 was fundamental to AC's commercial viability. Other key figures included Benjamin Garver Lamme, who made significant contributions to AC generator design; Charles F. Scott, who further refined AC generator and motor designs; and Oliver B. Shallenberger, who developed crucial AC metering and instrumentation. These individuals, working under Westinghouse’s direction, fostered an engineering-driven culture focused on relentless innovation and practical application. The company also established its primary manufacturing facilities in East Pittsburgh, Pennsylvania, which rapidly grew into a sprawling complex dedicated to producing electrical machinery. By the early 1890s, this site was employing thousands and became a hub for integrated research, development, and large-scale manufacturing, characteristic of Westinghouse's industrial strategy and its commitment to vertical integration.
Major milestones quickly followed, underscoring AC's growing acceptance. The company secured a highly coveted contract in 1889 to illuminate the World's Columbian Exposition in Chicago in 1893. This project, which involved installing twelve 1,000-horsepower two-phase AC generators and powering approximately 92,000 incandescent lamps across the vast fairgrounds, was a highly visible undertaking that showcased the capabilities of AC power to a global audience. Westinghouse significantly underbid its competitor, General Electric (formed from the merger of Edison General Electric and Thomson-Houston), offering to light the entire exposition for a fraction of GE's original bid. This contract was a significant public relations victory, demonstrating AC's safety, efficiency, and aesthetic appeal on an unprecedented scale, and effectively dispelling much of the negative propaganda—including sensational demonstrations of electrocution—spread by DC proponents like Edison, who had vehemently argued against AC's public use. The success at the Exposition proved instrumental in shifting both public and professional opinion towards AC as the superior system for widespread electrification.
The culmination of Westinghouse’s early efforts to achieve initial product-market fit came with the bid and subsequent contract award for the Niagara Falls hydroelectric project in 1893. This monumental undertaking involved harnessing the immense power of the falls to generate electricity for transmission to Buffalo, New York, over 20 miles away. An international commission, initially considering various power transmission methods, ultimately favored electricity, and Westinghouse’s polyphase AC generators and transmission system were chosen over competing DC alternatives, marking a decisive victory in the War of the Currents. The scale of the project was immense, with initial plans for five 5,000-horsepower, two-phase AC generators (later standardized to three-phase). This project, which commenced power delivery to Buffalo in 1896, was a watershed moment, demonstrating AC's capability for large-scale power generation and long-distance, high-voltage transmission (initially at 22,000 volts, 25 cycles). It solidified Westinghouse Electric Company’s position as a leading force in the electrical industry, effectively signaling the inevitable triumph of alternating current as the standard for electrification. The success at Niagara Falls provided undeniable validation for the company's core technology and business model, ushering in an era of unprecedented growth and diversification in the coming decades, and profoundly impacting industrial development across Western New York.
