Visiting the Electricity Transmission Site from Lauffen to Frankfurt am Main: Historical Site Guide

Date: 04/07/2025

Introduction

The Lauffen–Frankfurt electricity transmission site marks a defining moment in the evolution of electrical engineering and the modern power grid. Originating from the International Electrotechnical Exhibition of 1891, this site commemorates the world’s first successful long-distance, high-power transmission of three-phase alternating current (AC) over approximately 175 kilometers. This pioneering achievement resolved the “War of Currents,” proving the superiority of AC over direct current (DC) for long-distance transmission and laying the foundation for today’s interconnected electrical networks. Visitors to Frankfurt and the surrounding areas can explore this history through commemorative plaques, museum exhibits, and preserved infrastructure in Lauffen am Neckar (Deutsches Museum, ETHW, Wikipedia).

Historical Context and Purpose of the Exhibition

The International Electrotechnical Exhibition of 1891, held in Frankfurt am Main, was a turning point in the development of electrical power systems. Organized by Leopold Sonnemann and the Electro-Technical Society of Frankfurt, the exhibition aimed to resolve the ongoing debate surrounding the most effective electrical transmission system for the city—DC, single-phase AC, or three-phase AC. At a time when Frankfurt was searching for a central power solution, the exhibition’s demonstration of long-distance three-phase AC transmission proved the commercial viability of this technology, paving the way for the modern electrical grid (en-academic.com).

Technical Details of the Lauffen–Frankfurt Transmission

The landmark experiment transmitted electricity from a hydroelectric plant in Lauffen am Neckar to Frankfurt, covering approximately 175 kilometers. The system operated at 15,000 volts (15 kV) and 25 Hz, delivering around 220 kW of power with over 75% efficiency—a remarkable feat for the late 19th century. Key contributors included Oskar von Miller (project leader), Michael Dolivo-Dobrowolsky (AEG), and Charles Eugene Lancelot Brown (MFO). The transmission line was built using bare copper wires, supported by oil-filled insulators along the railway, requiring extensive collaboration among regional authorities (ETHW, radiomuseum.org).

Exhibition Highlights and Visitor Experience

From May 16 to October 19, 1891, the exhibition occupied the grounds of the former Western Railway Stations in central Frankfurt. Visitors entered through a grand arch inscribed with “Power Transmission Lauffen–Frankfurt 175 km,” illuminated by 1,000 electric bulbs. Inside, the demonstration included the lighting of 1,000 incandescent lamps and a 100-horsepower three-phase motor operating an artificial waterfall, symbolizing the conversion and application of electrical energy (Wikipedia, Deutsches Museum). Over 1.2 million visitors attended, underlining the public’s fascination with this technological breakthrough.

Technological and Cultural Significance

The exhibition conclusively ended the “War of Currents,” establishing three-phase AC as the preferred method for long-distance power transmission (Edison Tech Center). Prior to this, DC systems—championed by Thomas Edison—were limited to short distances. The Lauffen–Frankfurt demonstration proved that AC could supply cities from distant generation sites, enabling centralized, large-scale power distribution. This milestone laid the groundwork for today’s global electrical grids. Following the event, the Lauffen plant began supplying electricity to Heilbronn, making it the world’s first city with three-phase AC power (en-academic.com).

Culturally, the exhibition marked Frankfurt’s emergence as a center of industrial innovation during the second industrial revolution. Companies such as Hartmann & Braun and W Lahmeyer & Co. established a lasting presence in the city, cementing its role in the history of electrification.

Legacy and Historical Sites

Deutsches Museum, Munich

The Deutsches Museum in Munich preserves key artifacts, photographs, and models from the Lauffen–Frankfurt experiment. Exhibits include the original transformer station (1900), dioramas, and commemorative plaques. The museum’s Electric Power exhibition offers a deep dive into the technical achievements of the era (Deutsches Museum Digital).

Frankfurt am Main

Although the original exhibition grounds have been redeveloped, commemorative plaques in the Bahnhofsviertel and Gallusviertel districts mark the location and significance of the 1891 event (ETHW). The city’s museums, including the Museum für Kommunikation and Historisches Museum Frankfurt, occasionally feature related exhibits.

Lauffen am Neckar

Lauffen am Neckar honors its role as the starting point of the transmission with preserved sections of the original hydroelectric plant and infrastructure. The local utility company ZEAG recognizes the town’s pioneering legacy (everything.explained.today).
