Tanzania hakuna blackouts kwa miaka mingi sana sasa Tanesco walisha upgrade system zao kuondoa potential blackouts

World Bank report says otherwise. Anyway, labda 2019 mme improve quality ya stima so I will give you guys the benefit of doubt for now. Hapo SGR yenu ikianza kufanya kazi ... Baada ya kama miezi sita Hadi mwaka mmoja baadae tutajua mbivu na mbichi.

Bandari ya Mombasa imeongeza faida kutoka $380m Hadi $450m mwaka jana... Hio ni sector moja Tu ya logistics hatujaongelea impact yake Kwa Uchumi... Yani last week nilifurahia kusoma vile meli ilifika Msa na contena kama 6,000 na kama bado hawajamaliza kushukisha mizigo yote, tayari ilikua contena zilishoshukishwa zishafikishwa Nairobi wakati meli bado iko bandarini!!!
Gharama ya uendeshaji SGR nyingi huenda Kwa maintenance, fuel ... Hii ni gharama ambayo Sana Sana itabaki constant au kupanda kwa kiasi kidogo Sana .... Wakati Kwa upande mwengine revenue ya mizigo huongezeka exponentially Yani baada ya miezi sita ya Kwanza revenue iliongezeka mara dufu, baada ya miezi sita miengine revenue ikapanda mara 2.5 Yani inazidi kuongezeka kila baada ya miezi sita... Sahii ni mwaka mmoja na nusu tangu tuanze kubeba mizigo.... Kadri mizigo zaidi inazidi kubebwa na SGR revenue itazidi kupanda wakati gharama ya kusafirisha itaendelea kubaki Kwa range ile ile ...
BTW hata nyinyi mtapatwa na changamoto hio hio hapo mwanzo mwanzo, mtafikiria mmetengeneza faida alafu baada ya kulipa watu mishahara. TANESCO watabisha mlango na kudai hela Yao ya stima ...mwishowe mtajikuta na loss ..... Itabidi muendelee kuongeza mizigo zaidi Hadi ule wakati itakua mnabeba kama 60% ya mizigo yote inayoshuka bandarini.... Jambo ambalo haliwezi kufanyika mwaka wa Kwanza... Labda JPM aamuru TRA isilipe TANESCO gharama ya umeme ndo mtatengeneza instant profit!!!
BTW naona Yepi Merkezi ako bussy akieka milingoti ya stima lakini sijaskia mkianzisha project ya ku stabilize umeme Tz na kupunguza blackouts ... Chungeni msiwe kama Ethiopia, umeme wanao kwa wingi kuwashinda lakini bado electric train hukwama Kwa masaa njiani sababu stima zimepotea... Kwahivyo badala ya kuangalia ya huku Kenya ambayo tayari inafanya kazi, chunga sije ukajisahau kwamba mna yenu ya kutafakari Kwa hio yenu ambayo haijaanza kufanya kazi.

hii maneno ya umeme ni very tricky.Single tracked, one blackout and the whole system is clogged up.I foresee ALLOT of problems judging by how our utility companies are run.. DELAYS GALORE. Afadhali diesel.

Hakutakua na shida kwa sababu zita-switch to diesel mode boss...

Electric trains overhead mains draw power from multiple sources through a dedicated line in the event of power failure in one place the other sources will still be able to supply also locomotives do have onboard power sources should the situation get worse. Being a single track is not a problem there is an additional line running parallel to the main line for the case of Dar Moro the distance is 190km but over 300km of SGR rail track is being built accommodating the parallel tracks as well.

tlThat's the ideal situation..how things should be.Our situation is different. A trip on one source overloads the others causing the whole grid to collapse.
300-205 leaves you with only 95 km for the extra lanes at the marshaling yard, workshop, stations(mind you your trains are 2km long).There will be very few passing loops in my view.Tell me how a train stores AC current.. is that even posible
 
Have you came across of a term diesel-electric? the redundancy to accommodate the third word environment is already considered my dear friend, just look at the tender documents...

Hiyo system ya kizamani sana tz haiko siku hizi umeme ukikatika sehemu moja bado sehemu nyingine zinawaka Tanesco walishafanyia kazi hiyo kitambo ndio maana hakuna blackouts in tz anymore

Kazi ya stations na sustations za umeme inaendelea na mkandarasi mwingine siyo yapi. Kuna kituo kinajengwa kila baada ya kms 50. Kama huwa unaziangalia vizuri monthly progress videos za yapi, huwa kuna vituo vinaonekana upande wa kulia wa reli.

Kama umakini ukiwepo ni ngumu kutokea blackout coz umeme wa SGR utakuwa na special grid yake. SGR haitatumia umeme wa gridi ya taifa. Pia kuna kituo cha ku-step up\down umeme after every 50 km.

Hahaha.. hauju kile unachosema. Hakuna treni dual mode, hata kama iko, hamtazinunua. Stima zikifail, line yote hakuna mzigo itasonga. Ethiopia wamewaonesha example of how poor power delivery na production ina haribu the whole operation. Atleast 1 advantage of diesel is reliability. Only 1 delay in kenya sgr services in 2 years.
Theoretically, very little share of Dar port cargo will go onto SGR simply because Dar cargo is majority and will stay, its too hard for Uganda to receive the cargo(long route and bottle neck at lake Victoria), Rwanda and Burundi are tiny markets. Already cargo on only Kenya SGR is more than what Dar receives since Dar port is a third of Mombasa port. Hii profit ya Tanzania SGR itatoka wapi?

Yes I have, burning diesel to produce electricity. Kenya's train are diesel electric.
Not sure if you've tendered, last I checked you'd only invited bids.

Can you please stop PR..ing. Our institution/workforce are fckd up. We are mediocre and that's a reality that we should work.Case study, ethiopia.. our peers.
 
SGR line yenu sio electrified ndio maana diesel-electric train zenu zinafanya kazi kwa diesel mode only. You will need to upgrade your entire infrastructure, PS Macharia alishawapatia cost estimates ya ku-electrify Hio mChina wenu.

Sisi tulishaona hayo yote ndio maana tumeagaza vichwa ambavyo ni relevant to our environment, kama Ethiopia walikosea, tumewasoma pia...

Tanesco wanatumia grid loop na network looping system siku hizi hakuna overloads za ku cause blackout anymore as in the past

Zipo na zinaitwa electro diesel locomotives

Soma tuu hayo maelezo ya locomotives with duo power ujielimishe kdg uache ubishi

Diesel-electric locomotives sio dual mode but a diesel generator with electric traction motors for turning the wheels. What you mean is electro-diesel locomotives which are expensive and not widely used. Mpaka saa hii sijaona mpango yoyote ya ku unua locomotives ya TZ SGR na ati mnataka kuanza operatios November..., sioni kama zitakua hybrid locomotives.
Reasons for Kenya to use diesel first
1. Cheap to begin, no power lines to construct saa hii.
2. Kenya haina base load power reserves big enough to sustain reliable SGR trains. Maybe by 2025.
3. Diesel trains bado zitafanya kazi on electrified paths, so upgrades zinaeza fanywa pole pole.
4. Easier to do double stacking
5. Reliable and power grid issues independent. Kaxi haisimami the whole route
