This firm was organised in 1934 to develop the hydroelectric resources of the river Enns. Ownership of the firm is divided between the Government, who owns one third of the share capital, and investors from the private sector. The Government share is entrusted to the Staatlische Elektrizitätswirtschafts Gesellschaft.

The firm presently operates or is constructing four hydroelectric power stations, while others are projected.

Wasserkraftwerk Großraming – Initial planning of for the Großraming power station dates from 1926, but construction did not begin before 1934. It was substantially complete in late 1939 and began power production early in 1940. The length of the dam is 13.1 kilometers, with an average height of 23.5 meters. Three turbo-generators are installed, generating an average annual production of 244 million kilowatt-hours.

Wasserkraftwerk Ternberg – Located fifteen kilometers upstream from the town of Steyr the Ternberg hydroelectric station was intended to supply the factories of the city of Linz. Construction began in the spring of 1935, and was complete in mid 1941. The length of the dam is 7.8 meters, with an average eight of 15 metres. Two turbo-generators are installed, generating an average annual production of 168 million kilowatt hours.

This enterprise was organised in 1921 by the State of Baden to generate and distribute electricity from the Murgtalwerke hydro-electric generating station. The Murgtalwerke is fed by waters gathered by Murgtalsperre and Schwarzenbachtalsperre dams, and fed through a system of tunnels and pipes, and includes two turbine houses, each with a rated capacity of 44 megawatts, and a low-pressure pump house used primarily to store water within the system during off-peak demand. Construction of the system commenced in 1912 and was completed in 1926.

This enterprise was founded in 1924 to harness the waters of the Montafon valley to generate electricity. Construction of the reservoir of Vermuntsee commenced in 1926, and to date, four hydro-electric generating stations have been constructed together with the reservoirs, piping and tunnel systems that carry the waters of the valley through successive stations.

Vermuntwerk – a high pressure storage power station located at the end of the Valley of Montafon in Partenen, part of the Vorarlberger municipality Gaschurn. Construction of the reservoir commenced in 1926 and in 1930 the first four turbines, each of 22 Megawatts capacity, were brought on line. In 1939 a fifth unit of 40 Megawatts generating capacity was installed, raising the total generating capacity to 128 Megawatts, making this one of the largest hydro-electric generating stations in the nation.

Obervermuntwerk – a high pressure storage power station located upstream from the Vermuntwerk and drawing its water from the Silvretta-Stausee via a three-kilometre pipeline. Construction of the reservoir commenced in 1934 and in 1939 its two turbines, each of 18 Megawatts capacity, were brought on line.

Rodundwerk – located in the municipality of Vandans, this station draws its water from the Latschau reservoir, construction of which commenced in 1935 and in 1939 its two turbines, each of 40 Megawatts capacity, were brought on line.

Latschauwerk – this station utilizes the waters from the Latschau reservoir to power two turbines each of 4.5 Megawatts capacity. Construction of the station began in 1936 and it went on line early in 1941.

It is projected that at least four additional generating stations could be constructed at locations throughout the valley, and construction of the Lünersee reservoir and power station has begun, and is expected to complete some time in 1945.

This enterprise was founded in March 1894 as the municipal electricity supplier for the city of Hamburg and its surrounding districts. Half the shares were held by the city and the remaining shares were in the hands of Schuckert und Compagnie. The Fernheizwerk Hamburg GmbH coordinated the supply of steam generated by the enterprise’s power stations, and this combination provided powerful support for the firm’s growth over the next decades. In 1921 the enterprise was among the first to construct a cogeneration facility for the production of electricity and steam from industrial wastes.

The firm operates the following power stations:

Thermal power station Hammerbrook – completed 1896 – 25 MW installed capacity

This enterprise was founded in 1898 by the Elektrizitäts-AG vormals W. Lahmeyer und Compagnie and the Deutsche Gesellschaft für elektrische Unternehmungen to supply electricity to the city of Essen. In 1902 a consortium led by industrialists August Thyssen and Hugo Stinnes, backed by the Deutschen Bank, the Dresdner Bank and the Disconto-Gesellschaft took control of the enterprise and began a programme of expansion to serve the growing industrial area of the Ruhr Valley. In the subsequent years the enterprise absorbed a number of electric power companies, coal mines, and related firms, constructed great hydroelectric generating stations, built a network of power transmission lines and grew to be one of the largest electric utilities operating in Western Germany.

In 1906 it acquired the AG für Gas und Elektrizität (Köln) and the Bergisches Elektrizitätswerk (Solingen). These acquisitions were followed in 1909 by the Süddeutsche Eisenbahn-Gesellschaft (Darmstadt) and by the firm of Johann Wülfing und Sohn (Lennep) in 1911. The Niedersächsische Kraftwerke was absorbed in 1920, and the Lechwerke in 1923. That same year the enterprise acquired its original founder, the Elektrizitäts-AG vormals W. Lahmeyer und Compagnie. Purchase of the Rheinische AG für Braunkohlenbergbau und Brikettfabrikation (Köln) and the Koblenzer Elektrizitätswerk und Verkehrs AG (Koblenz) was consumated in 1932.

The company was founded in 1909 by Allgemeinen Elektrizitäts-Gesellschaft through their finance company Finanzierungsgesellschaft Gesellschaft für elektrische Unternehmungen (Gesfürel) . Shareholders were the Silesian provincial administration and some cities and municipalities of the coverage area and later the Elektrowerke AG. From 1909 it built a power grid to serve Middle Silesia, including the thermal power plants at Kraftborn, Tschechnitz and Mölke. In 1922 the concern took a majority holding in Niederschlesischen Elektrizitäts und Kleinbahn AG in Waldenburg, thus entering the business of local railways and supplying power to Lower Silesia. In 1927 an agreement was reached with Elektrowerke AG to enter into regional power-sharing arrangements, thus increasing the availability of power within its service area.

This concern was organised in 1922 as the municipal electrical supplier for the city of Wels in Upper Austria; the city holds one half of the shares in the enterprise with the remainder held by a consortium of banks. It operates several thermal power plants in the city and its immediate area, supplying not only electricity but also natural gas, a business undertaken by a subsidiary company, Welser Erdgas AG. Natural gas is used to power several of the thermal power plants operated by the concern.

This concern was founded in May 1884 by the Deutschen Edison-Gesellschaft to operate the concession of supplying the city of Berlin with electricity. In 1887 the management of the firm was taken over by the Allgemeine Elektricitäts-Gesellschaft; for a time, commencing in 1915, the assets of the firm were taken over by the Berlin municipal authorities, but in 1923 control of the citys electricity supply was returned to private hands and the firm adopted its present corporate style In 1934 the firm merged with the competing Berliner Kraft und Licht AG, which supplied electricity to the citys growing suburbs. At the present time the firm supplies not only light but gas, heat and water services with the area of Greater Berlin, and employs more than seven thousand, seven hundred workers.

Its thermal power plants include those at Berlin-Reuter, Berlin-Lichterfelde, Berlin-Charlottenburg, Berlin-Wilmersdorf, Berliin-Rudow, Berlin-Moabit, Berlin-Mitte, Berlin-Marzhan and Berlin-Buch.

This great utility concern was founded in 1855 on the strength of a concession granted by Duke Leopold Friedrich of Anhalt-Dessau, to build a gas plant in Dessau and supply the town with town gas for street lighting. The entrepreneur Hans Victor von Unruh and the Dessau banker Louis Nulandt were the driving forces behind the company, which was capitalised at half-a-million thalers, a very large sum for that time. The first gasworks in Dessau was completed in 1856, and the concern rapidly expanded to construct gasworks gas works in several dozen cities of home and abroad, including Mönchengladbach, Magdeburg, Frankfurt an der Oder, Mülheim am Ruhr, Potsdam, Warsaw, and Lvov. In 1859 Wilhelm Oechelhäuser emerged as the sole general director of the concern, which continued to expand its networks of gas supply across the nation. In 1871 the concern established the Centralwerkstatt Dessau, where new equipment, such as coin-operated gas meters and gas-consuming appliances such as lamps, stoves and engines were designed and manufactured. In 1921 the Centralwerkstatt merged with the Carl Bamberg Werkstätten für Präzisionsmechanik in Friedenau.

In 1883 the concern entered the field of electricity generation and distribution, obtaining a concession to erect Germany's second electricity-generation plant in Dessau. By the time of the Great War the generation of electricity absorbed much of its concern, and in 1915 concern took the lead in establishing the Elektrizitätswerk Sachsen-Anhalt in Halle, which marked the concerns entry into the great mid-German energy market. It remains one of the largest companies in Germany with a leading position in the gas and electricity markets and a dense network of investments. It employs more than sixty-thousand workers in its mines, works and distribution networks.

This major electric utility concern was established in 1923 with an initial capital of 10 million Reichsmarks, provided in part by the provincial administrations of Westphalia, Hesse and Lower Saxony and the remainder by a consortium of banks and the Allgemeine Elektricitäts-Gesellschaft. The concern is a major electricity supplier in the northern Rhine Valley and the Westphalian plain, having acquired by numerous smaller electricity supply firms as well as the municipal supply systems of major cities in the region.

Among the principal generating stations operated by the concern are:

Großkraftwerk Hannover – constructed between 1922 and 1924 and acquired in 1928; Present generation capacity 160 Megawatts
