Wazo huru: PPP's ya Tanesco na wamiliki wa nyumba Tanzania (133.2 gigawatts)

[Logikos]

Nishati ni muhimu sana katika Nchi na Tanzania kama nchi ya kitropiki imebarikiwa kuwe na Jua la kutosha ukiunganisha na vyanzo vingine vingi, vilevile kutokana na Vyanzo vya Maporomoko Nishati ya Jua inaweza ikaunganishwa na Maporomoko ya Maji ili kutengeneza battery ya kutunzia Nishati inayozalishwa (Pumped Hydro); Jinsi ya mfumo unavyofanya kazi nimeshauzungumzia kwenye Nyuzi nyingine.

Ila kwa ufupi ni kila nyumba kuwa connected na panels ambazo zitazalisha umeme na kuingizwa kwenye Grid; malipo kwa mzalishaji itakuwa ni kitu kinaitwa Net Metering ukizalisha zaidi Tanesco wanachukua ziada (inakupa credit) siku ukitumia umeme mwingi kuliko uzalishaji basi unakatwa kulingana na credit zako. Mfumo huu kwa mzalishaji utakuwa wa gharama ndogo sana sababu sasa hivi panels zimeshuka sana bei na nchi nyingi zinatoa ruzuku kwenye green energy; pia mfumo huu mtu hatakuwa na uhitaji wa battery.

Assumption:
Nyumba ina Panels Nne; Na Makadirio ya Kutoa 8kwh (Units Nane kwa Siku)

Kutokana na Sensa ya 2023

Tanzania ina makazi 14,152,803

Kwahio kama Nyumba hizo zitakuwa na panels nne kwa makadirio ya kuzalisha units Nane kwa siku; hivyo kuna uwezekano / capacity ya Watanzania / Wamiliki wa Nyumba kuwa wazalishaji wa Umeme na kuzalisha 113,222,424KW sawa na 113,222MW sawa na 113.2GW

Tunaongea kila siku watanzania binafsi kuingia UBIA na Serikali katika maendeleo na nadhani hakuna maendeleo kama ya kuhakikisha Nishati inapatikana na bila kutumia maeneo mahekari na mahekari ya kuweka solar panels.

Pia Tanesco itaendelea kuwa msambazaji wa kusambaza nishati inayozalisha na kukusanya kutoka kwa wazalishaji mbalimbali (so long as bei yao ni ndogo kuliko wanavyoweza kuzalisha wenyewe)

Tuanzie Tulipo, Tutumie Tulichonacho, Tufanye Tunachoweza​

Kama Umeme hautoshi tunajadili PPP ya Msambazaji ili Asambaze nini ?

Tuliambiwa umeme hautoshi ndio maana kukawa na Mgao, tunaambiwa hata Bwawa likiwa full Capacity (mara mbili ya uzalishaji wa sasa) bado bei hazitashuka sababu kuna mahitaji makubwa ya viwanda n.k. Sasa najiuliza hawa Adani na wengineo ambao eti wameleta ombi la kufanya usambazaji, wanasambaza...

This is too theoretical...
Na kama kw ndio unaita unit, then hauna uelewa wa hiki unachoeleza hapa.
Na kama definition ya pumped storage ndio hiyo uliyotoa, basi nakushauri ujikite kwenye ambayo una uelewa nayo...na nadhani power generation, transmission, distribution na storage sio miongoni mwa mambo hayo

 

[Logikos]

This is too theoretical...

Unajua kitu kinaitwa Direct to Grid

Na kama kw ndio unaita unit, then hauna uelewa wa hiki unachoeleza hapa.

Ukinunua Umeme wanauza kwa kitu gani kama sio Unit na Unit moja ni nini kama sio kwh; yaani wewe ukitoa 292/= unapewa kitu gani

Na kama definition ya pumped storage ndio hiyo uliyotoa, basi nakushauri ujikite kwenye ambayo una uelewa nayo..

Unadhani mabwawa (hydro electric power generetaion) yakiwa offpeak yanatumia nishati hio ku pump maji juu unadhani hicho kitu kinaitwa nini kama sio Pumped Storage Hydroelectric

.na nadhani power generation, transmission, distribution na storage sio miongoni mwa mambo hayo

nadhani asiyejua anachoongea ni wewe au unadhani hata wale watu walioongea na Makamba kuanza kuzalisha umeme wa Solar na kuwauzia Tanesco unadhani wakiwa wanazalisha nini kitatokea.... unadhani watakuwa wanaupakia kwenye matolori na kuupeleka Kidatu ?

Naomba pitia makala ya Direct to Grid Solar System alafu urudi tuendelee...

 

[Logikos]

This is too theoretical...

Narudia tena Soma Net Metering; Direct to Grid na Pumped Storage Hydroelectricity.., na kuhusu hii kitu kuwa theory ? Angalia baadhi ya nchi ambazo tayari wana policies kuhusu hiki kitu

Net Metering - energypedia.

 

[Logikos]

ujikite kwenye ambayo una uelewa nayo...na nadhani power generation, transmission, distribution na storage sio miongoni mwa mambo hayo

Mkuu Mtaalamu wa Umeme generation, transmission na distribution...; nikupe ushauri wa bure dunia ya leo kila information ipo waziwazi hii sio rocket science; pili theory za umeme as we know it hazijabadilika tangia enzi za kina Faraday na vile unavyozalisha umeme kwa kutumia dynamo ya baiskeli basics zake hazina tofauti na turbines huko kwenye Power generation...

Kwahio kwa wanasiasa na walamba asali kufanya haya mambo yaonekane complicated ndio sababu kuu ya watu kudanganywa na kuumizwa sababu hawafuatilii au wanadhani hii ni rocket science (ingawa hata rocket science is not that hard to follow)..., Sababu mimi sio kuku hainifanyi kushindwa kutambua Viza....

WE jamaa, haya mambo kwa ninavyoona unayaongelea itoshe kusema HAUNA uelewa nayo kabisa...siwezi kujadiliana na wewe hii mada.
Niliposema mwanzoni kuwa kuiita kW kuwa ndio Unit, badala ya kWh, ilitosha kuonyesha kuwa hata hizo hesabu zako haziwezi kuwa sawa.
Mambo ya Pumped storage mimi nayaishi hapa nilipo, na hiyo theoretical explanation unayotoa hata haipaint the real picture.
Kutengeneza Grid yenye mchanganyiko wa aina tofauti za Sources sio kazi nyepesi...kumbuka unakuwa na vyanzo vinavyozalisha AC, vingine DC, na vingine in a form of stored energy (be it chemical or otherwise). Kuhamornize haya yote sio lelemama....mnashindwa kuendesha grid hii yenye aina ya source zisizozidi 2, alafu ndio uweze kuendesha a multisource grid, some of which will have to kick in and out ghafla....
Narudia, ongelea unachofahamu...kwenye hili hujui kitu

WE jamaa, haya mambo kwa ninavyoona unayaongelea itoshe kusema HAUNA uelewa nayo kabisa...siwezi kujadiliana na wewe hii mada.

Okay kujadiliana au kutokujadiliana hio ni choice yako, sababu sikukuita wewe ndio ulikuja na mambo ya theoretical kwamba sio practical mimi ninajibu hio sasa kwamba kama ni theory which means haijafanyika popote okay.., nikakupa mifano ya direct to grid na net metering jambo ambalo linafanyika wala sio geni

Mambo ya Pumped storage mimi nayaishi hapa nilipo, na hiyo theoretical explanation unayotoa hata haipaint the real picture.

Pumped Hydro haina ugumu wowote katika kuelewa wala usitake ku complicate mambo... kwahio Hydro (denoting liquid / water) ikiwa pumped kwa kutumia pump ni kwamba unatunza Potential Energy yale maji yakirudi chini (the more the Height the better) yanakuwa na enegy ya kuweza kuzungusha tena turbines (hence working as a battery) na sababu Bwawa na maji yapo this is a very efficient battery (kuna watu wanajaribu kutumia Heavy weights; rolling trains (vyote hivyo not as effective kama maji) lakini Pumped Hydro Electric Storage imekuwa ikitumika tangu enzi na enzi...; sasa ukianza kuniambia mambo ya real picture wakati hata wewe ukijenga ghorofa lenye swimming pool mbili ukatumia mwaka mzima kuchukua maji chini kuyapeleka juu utakuwa umestore potential energy ambayo inaweza kutumika baadae

Kutengeneza Grid yenye mchanganyiko wa aina tofauti za Sources sio kazi nyepesi...

ooh kumbe sio kwamba haiwezekani ila sio nyepesi ? Mimi nilidhani ni theory ambayo haina practical application ?

kumbuka unakuwa na vyanzo vinavyozalisha AC, vingine DC, na vingine in a form of stored energy (be it chemical or otherwise).

Hivi hata sasa hivi as we currently go tuna vyanzo vya aina ngapi ? Hivi unajua hata Direct to Grid inakuwa na inverter ambayo inabadilisha DC kwenda kwenye AC kabla ya kuingiza kwenye GRID ? Huwezi kuweka DC kwenye GRID, pia hizo smart invetors zinakuwa zinasoma GRID kukiwa na cutoff automatically na yenye inajizima ili isiweze kuleta madhara wakati wati wanafanya service.... Soma hapo chini.....

Smart inverters are an emerging technology that can help integrate solar energy and other distributed energy resources (DERs) into the electric grid.

Like traditional inverters, smart inverters convert the direct current output of solar panels into the alternating current that can be used by consumers in their homes and businesses. Smart inverters go beyond this basic function to provide grid support functions, such as voltage regulation, frequency support, and ride-through capabilities.

As the number of DERs on the grid increases, the need for additional inverter functionality has grown.

Kuhamornize haya yote sio lelemama....

Okay not impossible ila unasema its not easy ? Okay by the way mikataba tuliyoingia na watu wazalishe umeme wa solar utaingizwa vipi kweny GRID

mnashindwa kuendesha grid hii yenye aina ya source zisizozidi 2, alafu ndio uweze kuendesha a multisource grid, some of which will have to kick in and out ghafla....
Narudia, ongelea unachofahamu...kwenye hili hujui kitu

Unazidi kujicontradict tuna source za umeme ambazo hazidi mbili ?; Okay ngoja nikupe hilo kwahio kumbe issue sio impossible ni kwamba sisi hatuwezi kufanya ? (Kwa taarifa yako inawezekena sababu sio sisi tutakaofanya bali ni vifaa ambavyo kwa sasa vipo vinavyoweza kusomana...) na kama kweli hatuwezi na tunataka kuingia UBIA na watu wenye uwezo huoni kwamba will be great to tap in more than 100 gigawatts za umeme ambazo zinapotea kutokana na solar daily ???? without even using extra land ambayo haitumiki kwa sasa ?

The Drakensberg Pumped Storage Scheme is an energy storage facility built in the South African provinces of Free State and KwaZulu-Natal starting in 1974 and completed by 1981.[2]

Four dams are involved in the scheme; the Driekloof Dam (joined to the Sterkfontein Dam), the Kilburn Dam, the Woodstock Dam and the Driel Barrage. Electricity generation equipment is located between Driekloof Dam and Kilburn Dam.[3] Since the Driekloof Dam/Sterkfontein Dam also forms part of the Tugela-Vaal Water Project some of the water pumped to Driekloof Dam might end up flowing to the Vaal Dam and not be available for return to the Kilburn Dam. The Woodstock Dam and Driel Barrage are used to supply this additional water to Kilburn Dam when required.

The scheme provides for up to 27.6 gigawatt-hours (99 TJ) of electricity storage in the form of 27,000,000 cubic metres (950,000,000 cu ft) of water. The water is pumped to Driekloof during times of low national power consumption (generally over weekends) and released back into Kilburn through four 250 megawatts (340,000 hp) turbine generators in times of high electricity demand.[1]

Niliposema mwanzoni kuwa kuiita kW kuwa ndio Unit, badala ya kWh, ilitosha kuonyesha kuwa hata hizo hesabu zako haziwezi kuwa sawa.

Terms Used:

• KWp: maximum power ambayo Panel inaweza kuzalisha.
• KWh: Nishati ambayo device inatumia kwa muktadha huu saa moja.

Assumptions:
Kupata Nishati itakayozalishwa na paneli inategemea mambo mengi kama vile mwanga wa jua, idadi ya masaa ya jua na ufanisi wa paneli. Hivyo jibu litakalopatina haliwezi kuwa sawa kwa kila panel au kila sehemu ndio maana tunachukulia average. Moja ya panel yenye ufanisi duniani Aiko ina power ya 620Wp, na ufanisi wa 24%. Kama hio ndio the best kuna nyingine zinachezea chini ya hapo

Ni Kiasi gani cha Nishati (Units) ambacho Paneli inaweza kuzalisha kwa Siku
Tukichukulia nchi ya kitropiki kama Tanzania tunaweza kusema tuna kama masaa 12 ya jua na kwa kutumia panel ya AIKO yenye 620p na ufanisi wa 24% tunaweza kusema kwamba tunaweza kupata 3.8 kWh kwa Siku

Lakini huenda kuna sehemu ambazo hazina jua sana na huenda kukawa na masaa ya jua kama sita au zaidi kidogo, hapo kwa kutumia panel hio hio huenda tukapata 2.5kWh kwa siku.

Kwahio kutokana na vitu tofauti tofauti, ufanisi wa panel, energy efficiency masaa ya jua, ndio maana it is widely estimated kwamba panel moja ya solar inaweza kutoa 2kWh kwa siku

Kwenye Mfano wangu nimesema kama nyumba ina panels nne basi itaweza kutoa 8units kwa Siku

Nikichukulia Makazi yaliyopo kutokana na Sensa iliyofanyika.....
Tanzania ina makazi 14,152,803

Kwahio kama Nyumba hizo zitakuwa na panels nne kwa makadirio ya kuzalisha units Nane kwa siku; hivyo kuna uwezekano / capacity ya Watanzania / Wamiliki wa Nyumba kuwa wazalishaji wa Umeme na kuzalisha 113,222,424KW sawa na 113,222MW sawa na 113.2GW

Nadhani tudeal na usambazaji wa umeme uliopo kwanza

 

[Logikos]

Nadhani tudeal na usambazaji wa umeme uliopo kwanza

Huo umeme umeshindwa kusambazwa vipi ? Kwamba tuna excess inayozalishwa ambayo imeshindwa kusambazwa ?

Tumeambiwa kwa kudanganywa kwamba umeme hautashuka hata tukimaliza Bwawa na Ku Double Capacity eti sababu matumizi yatakuwa yameongezeka (hivyo tutakuwa hatuna surplus)

Kwa wewe kusema hivi nadhani ushalishwa matango pori kwamba tunahitaji usambazaji hivyo kina ADANI wanahitajika...

Kama Umeme hautoshi tunajadili PPP ya Msambazaji ili Asambaze nini ?

Tuliambiwa umeme hautoshi ndio maana kukawa na Mgao, tunaambiwa hata Bwawa likiwa full Capacity (mara mbili ya uzalishaji wa sasa) bado bei hazitashuka sababu kuna mahitaji makubwa ya viwanda n.k. Sasa najiuliza hawa Adani na wengineo ambao eti wameleta ombi la kufanya usambazaji, wanasambaza...

UWEZEKANO WA 'REVERSE REDUNDANCY'...

Nyumba zenye kufua Umeme na kisha kuwa ni zinazojaza upya pumzi ya umeme kwenye 'gridi' ni uwezekano; na ndiyo, tayari hili linafanyika huku na kule Duniani... Inategemeana na Mazingira ya Eneo na Uwezo wake wa Kisuluhu... Lakini Je, si ni bora kuwa na chanzo kimoja na mtandao wake na halafu ukajumuishia yote ndani yake, consolidating investments, masuala yote ya kiuhandisi na ufundi na utawala?​

Kutengeneza Grid yenye mchanganyiko wa aina tofauti za Sources sio kazi nyepesi...kumbuka unakuwa na vyanzo vinavyozalisha AC, vingine DC, na vingine in a form of stored energy (be it chemical or otherwise). Kuhamornize haya yote sio lelemama....mnashindwa kuendesha grid hii yenye aina ya source zisizozidi 2, alafu ndio uweze kuendesha a multisource grid, some of which will have to kick in and out ghafla....

HII NI KWELI

Kwa hivyo ikiwa linawekwa shauri la 'Taasisi' ya watu binafsi, wenyekujiweza khasa, ifue umeme na kuiuzia TANESCO, hili linatengeneza hesabu fulani inayoweza kuwa na tija na manufaa ya 'kiuchumi mpana' na maendeleo ya mfumo wa usambazaji wa nishati ya umeme...

... ? ... "njia kuu za uchumi kutomilikiwa na watu wachache binafsi"... ?

Haya ni masuala yanayofungua kopo la chakula kilichochacha na minyoo mingi ndani yake... Masoko na Monopoli; TANESCO bado si 'Taasisi Huria'--inamengi ndani yake ambayo ni mvutano wa ndani kwa ndani kuhusiana na maslahi ya kweli ya Taifa na Usalama Kinishati wa Nchi-Dola...​
