Men de verkar faktiskt ha en del vattenkraft i byggfas nu.

Jag kollade bara en av de som var angivna i byggfas som skulle stå klar 2025, men idag verkar den anses bli klar först 2028. Jag kollade inget fler projekt.
Sen tänker jag att de där 1% avser produktion som matas in i landets elnät, att det troligen finns många gånger mer som försörjer enskilda hus eller smärre klungor av hus.

Sedan 60-talet har Sverige injicerat 70 Gkr i Tanzania (Palme var verklig kompis med Nyerere, för er som minns). Så nu är det landet väl förberett att ta tag i sina bekymmer. Eller?

på ett väldigt ytligt plan säger studien att under en del årtionden gav det svenska biståndet viktiga bidrag till att minska fattigdomen i Tanzania, under andra årtionden sågs inga sådana resultat, och ibland är det osäkert vilka resultaten var med avseende på fattigdom.

Vi byggde vattenkraft...men det gick ju sådärA ajn82 skrev:
The Rufiji Basin Survey initially had a focus on water usage AND electrification
At independence from Great Britain (1961) the Tanzanian government wished for development of electricity generation AND management of water resources (mainly for irrigation of agricultural land) and looked for another country as partner in development.
However, as Swedish development assistance and engineers entered the focus on single purpose hydropower – ignoring agriculture. As a consequence, the British dominance in the power sector was replaced by Swedish dominance with the disadvantage that earlier knowledge produced by British colonial officers was disregarded.
Why do you think this happened? Why did the Swedish engineers and development assistance focus on power production only?
At independence, Tanzania wanted to get rid of British influence and thus invited Sweden to plan the construction of a national electricity supply system, supported by the world bank. Tanzanian politicians decided on focussing on electrification amongst others because this is an indicator for the development of a country. This decision introduced the "Big Dam Era" from the 1960s to the 1990s. In 1990, 95 % of the electricity generation in Tanzania came from hydropower plants.
Sweden, at this time, had already an experienced hydropower industry (in this case represented by Sweco) that started to look for international projects. Sweco succeeded with a major hydropower export. Anyhow, there was little understanding of the local conditions. Dams were planned with a height of 15 meters from crest to foundation but without regarding the multipurpose usage of the rivers feeding the reservoirs.
The Rufiji River lies comletely in Tanzania and is additionally fed by the Great Ruaha River. The amount of water transported by these rivers made them interesting for hydropower exploration. Where the Great Ruaha River adds to the Rufiji River the Mtera Basin was planned. The Mtera dam was constructed from 1975 to 1979 and is the biggest hydroelectric dam built in Tanzania. Downstream, the Kidatu dam was built in two phases in 1975 and 1980.
The typical hydroelectric power station is built with a reservoir at the top of a mountain or hill. Tubes go down as deep as economically feasible to fed the turbines and then the water is led into a river bed. To the right, you can see a picture showing the Kidatu hydropower plant in the year 2000. Obviously, nearly no water is available for power production.
Problems which can be Identified From a Sociotechnical Perspective
Mtera basin at minimum shore level
Diesel generators have to back-up the national grid
The single usage for hydropower production that Mtera and Kidatu dams were built for, caused severe problems. Official warnings were sent to SWECO and the SIDA but anyhow the construction went on – unchanged. The Swedish technoscience paradigm transferred to Tanzania states that the construction of largescale hydropower plants were understood as important progress for Tanzania. The state considered the initialization of a national electricity grid as “greater benefit” for the nation. The local inhabitants and indigenous people of the affected regions were made “invisible” by the state. The massai were not taken into account when calculating the area of the river that was used - only their kettle - because the massai were meant to move to villages. The exploitation of the territory that was done in times of colonialism went on even when independence came.
This quote from a letter by a Swedish engineer working for Sweco, regarding the construction of the Mtera dam, was sent to the Swedish development agency in 1972:
“With its almost complete draw-down and consequent wide muddy shoreline, Mtera reservoir will be of little or no use for fisheries, for settlement or for watering animals, stock or game. Except very occasionally when full, the dam will not even be attractive to look at. Altogether therefore Mtera dam seems justified only to justify the development of Kidatu to its full 200 MW capacity: altogether Mtera dam will be wasteful of water resources and wasteful of good fertile land, 600 km2. – an area the size of Bahi swamp and just as wasteful. Large as it is Mtera dam will not even contain the largest floods which is experienced every 5-6 years. Some alternative to Mtera must be found even if it is more expensive
The main objective of Swedish Development Assistance was to export Swedish hydropower construction technology: In 1955, a pamphlet postulated that Sweden wants to help Tanzania. It was not hidden, however, that Swedish taxes were used to pay Swedish companies for constructing hydropower plants in Tanzania.

kräftgången med den svenska kärnkraftens dunkelflaute fortsätter – sedan andra halvan av maj har vi bara haft en halv reaktors produktion söder om Mälardalen (ena turbinen i Ringhals 4)
ikväll stängde man ner även den andra turbinen i Ringhals 4 och vi inleder därmed juli månad med minst tio dagar med noll kärnkraft söder om Mälardalen
turligt nog kom i alla fall Forsmark 2 tillbaka dygnet innan efter sin revision och lär vara uppe på sin nominella uteffekt på torsdag eftermiddag – därefter producerar alla tre reaktorerna i Forsmark för fullt igen
i år är Oskarshamn 3 är helt borta i minst 4.5 månader, Ringhals 3 är helt borta minst fyra månader och Ringhals 4 är borta med hel eller halv effekt i nästan fem månader
som bekant hävdas det att kärnkraften levererar året runt med bara kortare avbrott under sommaren...
under tiden har i alla fall elproduktionen från sol och vind i de södra elområdena SE3 och SE4 snittat 2.15 GW under maj och juni – eller snarare cirka 2.55 GW om vi inkluderar lokalt konsumerad el från egna solpaneler (produktionsfördelning: 57% vind, 43% sol)
