Grattis Olidan, 110 år!

25 mars 1910 invigdes Olidans kraftverk i Trollhättan, då landets största vattenkraftverk.

Lars-Magnus Kihlström

Olidestationen i Trollhättefallen började byggas redan innan Kungliga Vattenfallsstyrelsen bildades 1909. Det första sprängskottet gick av i juni 1906, och kraftverket togs i reguljär drift i mars 1910. Det var då Sveriges största vattenkraftverk.

Video: Hur det startade för 110 år sedan

Olidestationen byggdes med tilloppstuber ingjutna i bergtunnlar under markytan. Något som var ovanligt på den tiden. Det fanns flera skäl till detta, men en av anledningarna var att man inte ville inverka på de vackra omgivningarna och den speciella naturen.

Kraftverkets första fyra aggregat togs i drift 1910 och byggarbetet fortsatte fram till 1914 då ytterligare fyra aggregat kunde börja användas. På grund av den stigande efterfrågan på el och ökad kapacitet tack vare regleringen av Göta älv byggdes sedan ytterligare fem aggregat. 1921 hade Olidan totalt tretton turbiner, varav tio fortfarande är i bruk medan de övriga tre monterats isär för att få tillgång till reservdelar. Det är dock sällan som fler än tre av dem producerar el samtidigt. Varje turbin har en effekt på 10 MW.
