Porjus : en vision för industriell utveckling i övre Norrland

Sammanfattning: In the late 19th century it became possible to utilize electricity in lighting, industrial processes and for traction. To Sweden, which at that time was gradually being transformed from an overwhelmingly agrarian country into an industrialized nation, this was of great advantage because Sweden was a country well furnished with hydro-electric power, but almost completely lacking in other sources of energy. Beginning in the 1890's a number of privately-owned powerstations were built almost all over the country. During the early 20th century, the Swedish Government became increasingly involved in hydropower development. In 1906 the Government decided to make its debut as a power producer. A government bill proposing the building of a power station at Trollhättan was submitted to the Swedish Parliament, and Parliament approved this bill the same year. Two years later the State Power Board was formed, and in 19 10 Parliament approved plans to build a great power station at Porjus, on the Lule River in the north of Sweden. This power station is the main object of my study. The questions 1 shall try to give an answer to in my study are the following. Why did the State build a power station at Porjus? What happened to the industrial visions that initiated this project? On a more general level my dissertation intends to contribute to the understanding of the establishment of modem technological systems in Sweden. 1 shall try to achieve this by means of a model elaborated by Thomas P. Hughes, Professor of the History of Technology at the University of Pennsylvania. In Hughes' model technical systems are regarded as a part of a "socio-technical" or "technological" system. The core of the theory can be expressed in these words: "They are both socially constructed and society shaping." In my study, which consists of four parts, Part 1 is a study in which energy conditions in Sweden at the turn of the century are discussed in order to ascertain whether the prevailing sources of energy and power transmission methods are to be regarded as promotors of, or obstacles to a continued industrialisation. In Part 11 the following question is put in focus. Why did the State build one of its first big power stations in an area of wilderness in the north of Sweden? The answer to that question is given through a discussion in three steps. It starts with a discussion about why the Railway Board wanted to electrify the State railway. When the Railway Board made that decision they had intended to carry out the largescale trial electrification of a railway line in the western part of Sweden. In 1908 these plans were changed and the Railway Board decided to choose the Riksgräns Railway in the north of Sweden instead. The reasons for this change are discussed in a second step, and after that a discussion follows in which the choice of the Porjus Falls is explained. In Part 111 the dimensioning of the Porjussystem is discussed - i. e. the preliminary work that were needed to build the station, the power station, the transmission system and the locomotives. In the discussion problems connected with the locality of the Porjus Falls are emphasized. Part IV contains a discussion on the following theme. What happened with the industrial expectations which were once the main reason for the decision to build a power station at Porjus?
