Names of living persons are not normally used in citations. Exceptions to this are cases where the person's name is linked to the achievement itself (e.g. the Lempel-Ziv algorithm, Maxwell's Equations, etc.) or where the person's name is so widely recognizeable to the general public that it makes sense to use it. When used, the names should be the names of the engineers, scientists, or technologists who actually made the achievement, rather than managers or executives. For more information and suggestions about writing milestone citations, please visit Helpful Hints on Citations, Plaque Locations. The original Rheinfelden plant was an outstanding achievement in Europe's early large-scale generation of hydroelectric power. It was important for its 17,000 horsepower (12,500 kilowatt) output, for pioneering three-phase alternating current later adopted around the world, and using 50-Hertz frequency which afterwards became standard in most countries. Gradually, Rheinfelden entered into joint operation with other stations, from which the interconnected network of continental Europe evolved. German text: Will be submitted as soon as the final English wording is determined. In what IEEE section(s) will the milestone plaque(s) reside? Please specify the IEEE Organizational Unit(s) which have agreed to sponsor the Milestone, and supply name and contact information for the senior officer from those OU(s). Sponsorship has three aspects: 1) Payment for the cost of the plaque(s), 2) Arranging the dedication ceremony, and 3) agreeing to monitor the plaque and to let IEEE History Center staff know in case the plaque needs to be moved, is no longer secure, etc. Number 3 must be done by the IEEE Section(s) in which the plaque(s) is located, but aspects 1 and 2 can be done by any IEEE Organizational Unit, and they need not be the same one. Please note: your email address and contact information will be masked on the website for privacy reasons. Only IEEE History Center Staff will be able to view the email address.

Please include coordinates in decimal format rather than degrees. What is the intended site(s) of the milestone plaque(s) relation to the achievement? The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque. Also, please Describe briefly the intended site(s) of the milestone plaque(s). (e.g. Is it corporate buildings? Historic Site? Residential? Are there other historical markers already at the site?) Are the original buildings extant? Please provide the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. How is the intended plaque site protected/secured, and in what ways is it accessible to the public? If visitors to the plaque site will need to go through security, or make an appointment, please give details as well as the contact information visitors will need in order to arrange to visit the plaque. Who is the present owner of the site(s)? In the space below, please describe in detail: the historic significance of the achievement, its importance to the evolution of electrical and computer engineering and science, its importance to regional/national/international development, its benefits to humanity, the ways the achievement was a significant advance rather than an incremental improvement of existing technology. The material submitted here will constitute the main descriptive article on the ETHW website for readers to learn about the milestone. Space is unlimited, and detail is encouraged. Most milestones require 1000 to 1500 words of support, however there is no word limit. The article should be readable by a wide audience that includes practicing engineers, scholars of history, and the general public. Some examples of the text of good milestone articles are First Radio Astronomical Observations Using Very Long Baseline Interferometry] and G3_Facsimile International Standardization of G3 Facsimile (Do not worry about the formatting of the page, IEEE History Center Staff will do that afterwards.) What is the historical significance of the work (its technological, scientific, or social importance)? The old hydro-power station Rheinfelden is a pearl from the early stages of real electric power supply in Europe. The power plant stands for the beginnings of large-scale generation of electricity from hydropower, including the transmission to consumer centers. The power company adopted the name “Rheinfelden Power Generation and Transmission Company” and thus expressed the dual role of the enterprise. The plant was commissioned in 1898. Thanks to an innovative design it became possible to derive a legendary 17’000 horse power in electrical form from the River Rhine and to transmit this via high-voltage lines to consumer centers. Three years earlier, the very first large-scale hydropower station in the world had been completed. In North America courageous engineers had succeeded in tapping the power of the giant Niagara Falls. From 1895 hydraulic turbines extracted from the water complex the power of 15’000 hp, to be converted into electric power by generators and transported via transmission lines to nearby cities. The two large-scale power plants are milestones in a development process reflecting the dawn of modern electric power supply. What current type or current system and what frequency should best be applied, was by no means clear. At that time, there was still a system conflict concerning the struggle to decide on the best current system and the best suitable alternation number (later called “frequency”) of the current. The planning engineers and manufacturers of the electrical equipment for Rheinfelden decided, after thorough investigations, for “three-phase alternating current” with 50 periods per second, the “50-Hz rotary current”. It was a decision that was to give the power station a high technical prominence and exemplary role, right up to the present. Thanks to step-by-step improvements and partial retrofits, the electric output − originally 12’500 Kilowatt − was ultimately increased to 25’000 kW. Two of the original three-phase ac generators were providing reliable service until decommissioning in 2011. A few years after commissioning, the Rheinfelden hydropower plant was interconnected for operation with other power stations on both sides of the German-Swiss border and became the nucleus of today’s interconnected network of Europe. This is the second particularity for which the Rheinfelden power plant can claim for being the very first district power station of the world with trans-border operation. What obstacles (technical, political, geographic) needed to be overcome? At that time a future oriented and courageous decision had to be made • out of the jungle of different frequency proposals for alternating current (tendencies: rather high for electric lighting and distribution, rather low for power purposes and transmission), • forward to a best appropriate number of phases ( 1, 2 or 3 ) • away with the use of various current systems (dependent on lighting or power, distribution or transmission) and focus on general system • for well accepting the offered new type of energy, called electricity, for public supply and variety of applications What features set this work apart from similar achievements? When the Rheinfelden power plant was being prepared, no ideal examples existed to help decide which basic current system and what number of cycles should best be used (it was the time of “war of the currents” and “war of the frequencies”). Comparable predecessors had most diverse characteristics in this respect: For instance, the large-scale power transmission experiment Lauffen-Frankfurt in 1891 operated with the brand-new three-phase alternating current (ac) system but with 40 cycles, by 1895 Niagara Falls went into operation with two-phase ac and 25 cycles, in certain regions of Europe 42 cycles had been established, only some sporadic new plants went into operation with 50 cycles. Most of the new power stations of that time were equipped with single-phase or two-phase ac generators, until about 1897. With the decision for three-phase ac with 50 cycles the Rheinfelden power plant set new standards and launched the triumphant progress “of the right current system”, suitable for both lighting and power purposes.
