Hojum Hydroelectric Power Station
Hojum Power Station (alt. ''Håjum Power Station'') is the second hydroelectric power station in Trollhättan, the first one being the older Olidan Power Station. While the first two turbines were taken into service in 1938, a third one was built and started in 1992. The first two are rated at 50 MW, while the third is rated at 70 MW. The station is mainly located underground in a large mountain hall. This design was chosen because of the political instability in Europe at the time, which later led to the second world war. The relatively small building above ground was drawn by the Swedish architect An architect is a person who plans, designs, and oversees the construction of buildings.

Hydroelectric Power
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Trollhättan
Trollhättan () is the 23rd-largest city in Sweden, the seat of Trollhättan Municipality, Västra Götaland County. It is situated by Göta älv, near the lake Vänern, and has a population of approximately 50,000 in the city proper. It is located 75 km (46 mi) north of Sweden's second-largest city, Gothenburg. History Trollhättan was granted city rights (which today have no legal effect) in 1916 at which time it had about 15,000 inhabitants, now grown to 59,058. Trollhättan was founded on the river Göta älv, at the Trollhättan Falls. The site was first mentioned in literature from 1413. Trollhättan had a strategic significance on the road between Västergötland and Norway. It was also of a commercial and political significance for shipping to and from Vänern. Utilization of the river falls was the first important business activity in the area. From the Middle Ages milling and sawing operations have been conducted where the city center is now located.

Olidan Power Station
Olidan Power Station () is a hydroelectric power station located in Trollhättan, Sweden. First opened in 1910, it was the first large scale attempt at generating electricity from water in Sweden. The construction of Olidan led to the founding of the ''Kungliga Vattenfallsstyrelsen'' (Royal Waterfall Board), which later became Vattenfall. While the first four turbines were put into service in 1910, construction continued, and another four were put into operation by 1914. Due to increasing demand, as well as increasing capacity due to the regulation of Göta älv The (; "River of (the) Geats") is a river that drains lake Vänern into the Kattegat, at the city of Gothenburg, on the western coast of Sweden. It was formed at the end of the last glaciation, as an outflow channel from the Baltic Ice Lake to ..., another five were then built. By 1921, Olidan carried a total of 13 turbines. 10 of these are still functioning, while the other three were cannibalized for parts. Howeve ...

Architect
An architect is a person who plans, designs, and oversees the construction of buildings. To practice architecture means to provide services in connection with the design of buildings and the space within the site surrounding the buildings that have human occupancy or use as their principal purpose. Etymologically, the term architect derives from the Latin , which derives from the Greek (''-'', chief + , builder), i.e., chief builder. The professional requirements for architects vary from location to location. An architect's decisions affect public safety, and thus the architect must undergo specialised training consisting of advanced education and a ''practicum'' (or internship) for practical experience to earn a Occupational licensing, license to practice architecture. Practical, technical, and academic requirements for becoming an architect vary by jurisdiction though the formal study of architecture in academic institutions has played a pivotal role in the development of the p ...

Vattenfall
Vattenfall is a Swedish multinational corporation, multinational electrical power industry, power company owned by the List of government enterprises of Sweden, Swedish state. Beyond Sweden, the company generates power in Denmark, Finland, Germany, the Netherlands, and the United Kingdom. The company's name is Swedish for "waterfall", and is an abbreviation of its original name, Royal Waterfall Board (''Kungliga Vattenfallsstyrelsen''). History Vattenfall (then called ''Kungliga Vattenfallsstyrelsen'' or Royal Waterfall Board) was founded in 1909 as a state-owned enterprise in Sweden. From its founding until the mid-1970s, Vattenfall's business was largely restricted to Sweden, with a focus on hydroelectric power generation. Only in 1974 did the company begin to build nuclear reactors in Sweden (the Ringhals Nuclear Power Plant, Ringhals 1 and 2 reactors), eventually owning seven of Sweden's 12 reactors. In 1992, Vattenfall was reformed as the Aktiebolag, joint-stock company Vat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
