The Kaplan Turbine -- a Hydropower Innovation Celebrates its 100th Birthday: Great-Grandson of the Inventor Visits Voith in Heidenheim - Viktor Kaplan was closely associated with Voith; the company made study and research visits possible for him

- Continuous development of the Kaplan technology in terms of ecology and economy

HEIDENHEIM, Germany, Sept. 4, 2013 /PRNewswire/ -- History unites: on 7 August 1913, Viktor Kaplan registered the patent for the Kaplan turbine in Austria. And 100 years later his great-grandson Roland Athenstaedt with two of his sons returns to a workplace vital for the development of the Kaplan turbine: Voith in Heidenheim. Last week, the three Athenstaedts visited Voith in order to get am impression of the place where the history and the future of hydropower merge.

"My children are currently looking at forms of renewable energy at school. I therefore thought it would be a good idea to explain hydropower to them and show them the company where their great-great-grandfather had carried out active research," says Roland Athenstaedt. The 46-year-old engineer is fascinated by the sustainable character of hydropower plants, which often last across generations and supply eco-friendly electricity. During a tour through the turbine production and the global test and development center "Brunnenmuehle" in Heidenheim, Roland Athenstaedt and his children gained an insight into one of the world's leading production sites for hydropower components. Here, Kaplan turbines are still being designed and produced.

Viktor Kaplan and Voith
The history of the Kaplan turbine is closely associated with the development of the company Voith. Viktor Kaplan visited the company for the first time during a study trip in 1912. A number of study and research visits in Heidenheim followed over the next few years. There he made frequent use of the company's former test laboratory in Hermaringen near Heidenheim. The contact between the former Voith CEO Walther Voith and Viktor Kaplan gradually intensified. They became friends, which is documented by the many letters exchanged between them. Regarding the development of the Kaplan turbine, Viktor Kaplan once called Walther Voith the "discoverer of my invention." Later, during the 1920s, Kaplan granted Voith the option to utilize the US patents of his turbine, if he received half of the license earnings.

Voith promoted and still promotes the application of Kaplan turbines
In 1922 Voith began with the production of Kaplan turbines and manufactured two units for the power station of the Steyrermuhl paper mill in Upper Austria. The business with Kaplan's invention rapidly increased, and in 1928 Voith built four machine sets for the power plant Rheinkraftwerk Ryburg-Schworstadt with Kaplan turbines in record dimensions. Each of them had a diameter of seven meters. At that time they were the largest Kaplan runners in the world. 

During the last decades, Voith became one of the most important manufacturers of Kaplan turbines. In the U.S., Voith's York, Pennsylvania facility is supplying two Kaplan turbines for the expansion of the nearby Holtwood Hydroelectric Plant on the Susquehanna River, scheduled to go on line this year. The two 65 MW, 7.15 meter units are helping to double the over 100 year old plant's capacity. This is just one of the numerous hydropower modernization projects which Voith carries out all over the world.

In addition, more and more energy suppliers use innovative Kaplan turbines for their plants: so-called fish-friendly Kaplan turbines are particularly popular in the United States. Since the invention of the Kaplan turbine, energy companies have purchased nearly 10,000 units for their power stations. Worldwide, Kaplan turbines with a capacity of approximately 200 GW are installed. This corresponds to the output of about 200 large coal-fired power stations.

The Importance of Hydropower
Hydropower is the largest, oldest and also most reliable form of renewable energy generation. Worldwide it makes an indispensable contribution to stable power supplies and hence to economic and social development - in industrial countries and also in rapidly growing regions. At the same time, hydropower significantly contributes to climate-protecting energy generation. Voith has been a leading supplier of this technology since the early beginning of hydropower utilization, and continuously develops and improves this technology.

About the Company
Voith sets standards in the markets energy, oil & gas, paper, raw materials and transportation & automotive. Founded in 1867, Voith employs more than 42,000 people, generates € 5.7 billion in sales, operates in about 50 countries around the world and is today one of the biggest family-owned companies in Europe.
