Case study in Järbo : An investigation of the prerequisites for restart of a discontinued, smallscale hydropower plant (English)
Abstract [sv]

Utsikterna att kunna genomföra en återstart av de två små vattenkraftverk som behandlas i denna rapport år goda. Förutsättningarna är gynnsamma i så måtto att planerna för återstarten ligger väl i linje med praxis som etablerats genom avgöranden i de högre rättsliga instanserna gällande liknande fall. Ägaren planerar att driva verksamheten i stort sett så som den ursprungligen bedrevs, vilket visat sig betydelsefullt för att få återupptag av nedlagd vattenkraftverksamhet godkänt Dessa kraftverk är små, väldigt små. Detta betyder att investeringskostnaderna måste minimeras om det skall finns någon chans att uppnå en acceptabel återbetalningstid för investeringen. Några kostnader kan inte påverkas alls, till exempel anslutningen till elnätet. Vissa, såsom de för nya tuber, intagsgaller, samt kabel och utrustning till kraftverken, kan påverkas i någon mån genom att omsorgsfullt välja leverantörerna av utrustningen, samt välja de mest kostnadseffektiva (ofta liktydigt med de enklaste men ändå fungerande) lösningarna. Några få komponenter, såsom generatorn, kan gå att få tag på som begagnade, vilket hjälper till att hålla nere kostnaderna. Slutligen bör inte de pengar som finns att spara på att göra så mycket som möjligt av arbetet själv underskattas.

Abstract [en]

The prospects of achieving a restart of the two small hydropower plants studied in this report are good. The basic conditions are favourable in the sense that the plans for a restart are well in line with accepted procedures such as established by decisions in the highest courts regarding similar cases. The owner plans to run the operation in essentially the same way it was originally run, a circumstance which has proven to be important when seeking to get restart of discontinued hydropower activities approved. These power plants are small, very small. This means that investment costs has to be minimized if there is to be any chance of achieving an acceptable pay-off time for the investment. Some can't be affected at all, such as the cost for getting connected to the power network. Some, such as those of new tubes, intake bars and electrical wiring and equipment for the plants, can be affected to some extent by carefully choosing the suppliers of the equipment and choosing the most cost-efficient (in most cases synonymous with the simplest but yet functional) solutions. A few components, such as the generator, can possibly be obtained as used equipment, which helps keeping the costs down. Lastly, the potential of saving money by doing as much as possible of the work yourself should not be underestimated.
