UNeil Etter, umqhubi wegumbi lokulawula eSiteshini Sokukhiqiza sika-H. Wilson Sundt sikaTucson Power.
I-Tucson Power ithe inamandla anele okuhlangabezana nokuphakama kwesidingo okulindelekile nokugcina ama-air conditioner ekhala kuleli hlobo.
Kodwa ngokushintsha kwezitshalo ezisebenzisa amalahle kuya ezinsizeni zelanga nezomoya, amazinga okushisa asehlobo aphakeme kakhulu kanye nemakethe yamandla eqinile entshonalanga, izinhlelo zokugwema ukucima ziya ngokuya ziba nzima, kusho i-TEP kanye nezinye izikhungo zemisebenzi ngesonto eledlule.
Ngokusho kocwaningo olusha oluxhaswe yi-TEP kanye nezinye izinsiza zaseNingizimu-ntshonalanga, ngo-2025, uma yonke imisebenzi yamandla avuselelekayo ehleliwe eNingizimu-ntshonalanga ingaqedwa ngesikhathi, ngeke ikwazi ukuhlangabezana nesidingo sikagesi esikhulayo.
Emhlanganweni wokulungiselela ihlobo waminyaka yonke we-Arizona Corporation Commission ngesonto eledlule, izikhulu ezivela ku-TEP kanye nozakwabo basemakhaya i-UniSource Energy Services bathi banamandla okukhiqiza anele ukuhlangabezana nesidingo esikhulu sasehlobo okulindeleke ukuthi sidlule amazinga ka-2021.
“Sine-energy eyanele futhi sizizwa sikulungele kahle ukushisa kwasehlobo kanye nesidingo esikhulu samandla,” kusho okhulumela i-TEP uJoe Barrios. “Kodwa-ke, sizoqapha isimo sezulu eduze kanye nemakethe yethu yamandla yesifunda, sinezinhlelo zokubhekana nezimo uma kwenzeka kuba nesimo esiphuthumayo.”
I-Arizona Public Service, inkampani kagesi enkulu kunazo zonke esifundazweni, iSalt River Project ezibusayo kanye ne-Arizona Electric Cooperative, enika amandla ama-cooperative kagesi asemakhaya esifundazweni, nayo itshele abalawuli ukuthi banamandla anele okuhlangabezana nesidingo sasehlobo esilindelekile.
Ukuthembeka kwasehlobo kube yinto ekhathazayo kakhulu kusukela ngo-Agasti 2020, lapho ukushoda kukagesi ngesikhathi sokushisa okungokomlando eNtshonalanga kwashukumisela opharetha besistimu yokudlulisa ugesi eCalifornia ukuthi baqalise ukucima ugesi ukuze bagweme ukuwa kohlelo lonke.
I-Arizona ikwazile ukugwema ukungasebenzi kahle ngokwengxenye ngezinhlelo zokuphendula isidingo kanye nemizamo yokuvikela amakhasimende, kodwa abakhokhi bentela besifundazwe bathwala izindleko zokwenyuka kwamanani kagesi wesifunda ngesikhathi senhlekelele.
Kuyo yonke indawo, ukuhlela izinsiza kuye kwaba nzima kakhulu ngenxa yokushisa okukhulu kwehlobo kanye nesomiso, imikhawulo ekungenisweni kukagesi eCalifornia, izintambo zokuhlinzeka kanye nezinye izinto ezithinta amaphrojekthi elanga kanye nezindawo zokugcina, kusho uLee Alter, umqondisi wokuhlela izinsiza ze-TEP kanye ne-UES, etshela abalawuli.
Ngokusekelwe esidingweni esibonisa amazinga okushisa asehlobo ajwayelekile, inkampani izongena ehlobo inesilinganiso esiphelele sokugcina (esikhiqiza okungaphezu kwesidingo esibikezelwe) esingu-16%, kusho u-Alter.
Uchwepheshe uDarrell Neil usebenza kwelinye lamahholo eSiteshi Sikagesi i-H. Wilson Sundt eTucson, esinezinjini ezinhlanu kweziyi-10 ze-TEP ezishintshanayo.
Imingcele egciniwe inikeza izinsizakusebenza isivikelo ngokumelene nesidingo esiphezulu kunalokho obekulindelwe ngenxa yesimo sezulu esibi kakhulu kanye nokuphazamiseka kokuhlinzekwa, njengokuvalwa kwezitshalo zikagesi okungahleliwe noma umonakalo womlilo wasendle ezintambo zokudlulisa ugesi.
IBhodi Yokuxhumanisa Amandla Kagesi YaseNtshonalanga ithe kudingeka isilinganiso sonyaka esigciniwe esingamaphesenti ayi-16 ukuze kulondolozwe izinsiza ezanele ogwadule oluseningizimu-ntshonalanga, okuhlanganisa ne-Arizona, kuze kube ngu-2021.
I-Arizona Public Service Co. ilindele ukuthi isidingo esiphezulu sizokwenyuka cishe ngamaphesenti ama-4 siye kuma-megawatts angu-7,881, futhi ihlela ukugcina isilinganiso esigciniwe esingamaphesenti angaba ngu-15.
U-Ort uthe kunzima ukuthola imithombo yamandla eyengeziwe eyanele, njengezinkontileka ezihleliwe zokudluliselwa kwamandla esikhathini esizayo, ukuze kwandiswe imingcele yokugcina amandla phakathi kwezimakethe zamandla eziqinile eNtshonalanga.
“Esikhathini esidlule, kwakunomthamo owanele esifundeni kangangokuthi uma ufuna okwengeziwe, ubuyothenga okwengeziwe, kodwa imakethe isiqine kakhulu,” kusho u-Alter ekomitini lezinkampani.
U-Alter uphinde waveza ukukhathazeka okukhulayo kokuthi isomiso esihlala isikhathi eside eMfuleni iColorado singamisa ukukhiqizwa kukagesi ngamanzi eGlen Canyon Dam noma eHoover Dam, kuyilapho opharetha wegridi yaseCalifornia eqhubeka nenqubomgomo eyamukelwe ngonyaka odlule yokunciphisa ugesi ophuthumayo ukuthunyelwa kwamanye amazwe kukagesi.
UBarrios uthe i-TEP ne-UES azithembeli emadamini oMfula iColorado ukuze zithole amandla kagesi, kodwa ukulahlekelwa yilezo zinsiza kuzosho ukuthi amandla kagesi aphansi atholakala esifundeni futhi kukhuphule ukushoda kanye namanani.
Okuhle kakhulu, i-TEP ngesonto eledlule iqale ukuhlanganyela eMakethe ye-Western Energy Imbalance, imakethe kagesi ethengiswa ngobuningi ngesikhathi sangempela yezinsizakusebenza ezingaba ngu-20 eziphethwe yi-California Independent System Operator.
Nakuba ingangezi amandla okukhiqiza ugesi, imakethe izosiza i-TEP ukulinganisela izinsiza ezihlala njalo njengelanga nomoya, ivimbele ukungazinzi kwegridi futhi ithuthukise ukuthembeka kohlelo, kusho u-Alter.
I-Tucson Power kanye nezinye izikhungo zikagesi zitshele abalawuli bakahulumeni ngesonto eledlule ukuthi izinhlelo zokugwema ukucima kukagesi ziya ngokuya ziba nzima phakathi kokushintsha kwezitshalo ezisebenzisa amalahle ziye ezinsizeni zelanga nezomoya, amazinga okushisa ehlobo aphakeme kakhulu kanye nemakethe yamandla yasentshonalanga eqinile.
Ecaphuna ucwaningo lwakamuva lwe-Environmental + Energy Economics (E3), u-Alter uthe i-TEP kanye nezinye izikhungo zikagesi zaseNingizimu-ntshonalanga zibhekene nezinselelo ezinkulu ekuhlangabezaneni nesidingo esikhulu sikagesi njengoba zishintsha kusukela ekukhiqizweni kwamalahle eminyakeni ezayo.
“Ukukhula kwemithwalo kanye nokususwa kwezinsiza kudala isidingo esibalulekile nesiphuthumayo sezinsiza ezintsha eNingizimu-ntshonalanga,” kusho i-E3, umbiko oqashwe yi-TEP, i-Arizona Public Service, i-Salt River Project, i-Arizona Electric Cooperative, i-El Paso Power write.. kanye ne-New Mexico Public Service Corporation.
“Ukugcina ukuthembeka kwesifunda kuzoncika ekutheni izinsizakusebenza zingangeza yini izinsizakusebenza ezintsha ngokushesha ngokwanele ukuze kuhlangatshezwane nalesi sidingo esikhulayo futhi kudingeke isivinini esingakaze sibonwe sentuthuko esifundeni,” kuphetha ucwaningo.
Kuyo yonke indawo, izikhungo zikagesi zizobhekana nokushoda kwesizukulwane esingaba ngu-4 GW ngo-2025, njengoba izinsizakusebenza nezitshalo ezikhona njengamanje zithuthukiswa. I-1 GW noma i-1,000 MW yamandla elanga afakiwe anele ukunika amandla amakhaya angaba ngu-200,000 kuya ku-250,000 esifundeni se-TEP.
I-Southwest Utilities ilungiselela isidingo esikhulu, ithembisa ukwengeza cishe ama-gigawatts ama-5 kagesi omusha, kanye nezinhlelo zokwengeza amanye ama-gigawatts angu-14.4 ngo-2025, kusho umbiko.
Kodwa umbiko we-E3 uthe noma yikuphi ukubambezeleka ezinhlelweni zokwakha zale nkampani kungaholela ekushodeni kukagesi esikhathini esizayo, okungase kukhulise izingozi zokuthembeka kohlelo iminyaka eyishumi noma ngaphezulu.
“Nakuba le ngozi ingase ibonakale ikude ngaphansi kwezimo ezivamile, ukuphazamiseka kochungechunge lokuhlinzekwa kwempahla, ukuntuleka kwezinto zokwakha kanye nezimakethe zabasebenzi eziqinile kuthinte isikhathi samaphrojekthi ezweni lonke,” kusho ucwaningo.
Ngo-2021, i-TEP yengeze ama-megawatt angu-449 emithombo yomoya neyelanga, okwenza inkampani ikwazi ukuhlinzeka cishe ngo-30% kagesi wayo ovela emithonjeni evuselelekayo.
Ngokusho kocwaningo olusha oluxhaswe yi-TEP kanye nezinye izinsiza zaseNingizimu-ntshonalanga, ngo-2025, uma yonke imisebenzi yamandla avuselelekayo ehleliwe eNingizimu-ntshonalanga ingaqedwa ngesikhathi, ngeke ikwazi ukuhlangabezana nesidingo sikagesi esikhulayo.
I-TEP inomklamo welanga osakhiwayo, iphrojekthi yelanga yeRaptor Ridge PV engu-15 MW eduze ne-East Valencia Road kanye ne-Interstate 10, okulindeleke ukuthi iqale ukusebenza kamuva kulo nyaka, ixhaswe uhlelo lokubhalisela amakhasimende lwelanga iGoSolar Home.
Ekuqaleni kuka-Ephreli, i-TEP yamemezela isicelo esiphelele seziphakamiso zamandla avuselelekayo kanye nezinsizakusebenza kahle kwamandla ezingafika ku-250 megawatts, okuhlanganisa ilanga nomoya, kanye nohlelo lokuphendula isidingo ukunciphisa ukusetshenziswa ngezikhathi zesidingo esikhulu. I-TEP iphinde ifune izinsizakusebenza "ezinamandla aqinile" ezingafika ku-300MW, okuhlanganisa nezinhlelo zokugcina amandla ezihlinzeka okungenani amahora amane ngosuku ehlobo, noma izinhlelo zokuphendula isidingo.
I-UES ikhiphe amathenda ezinsizakusebenza zamandla avuselelekayo kanye nokusebenza kahle kwamandla afinyelela ku-170 MW kanye nezinsizakusebenza zamandla ezinkampani ezifinyelela ku-150 MW.
I-TEP kanye ne-UES balindele ukuthi umthombo omusha ube ususebenza kangcono ngoMeyi 2024, kodwa kungakedluli uMeyi 2025.
Isitezi sejenereyitha ye-turbine eSiteshini Sikagesi i-H. Wilson Sundt ku-3950 E. Irvington Road ngo-2017.
Phakathi nokuphela kwesikhathi kwezitshalo zikagesi ezisebenzisa amalahle, i-TEP idinga ukuthatha isinyathelo ngokushesha, okuhlanganisa nokuvalwa okuhleliwe ngoJuni kwe-Unit 1 engu-170-megawatt eSan Juan Power Station enyakatho-ntshonalanga yeNew Mexico.
UBarrios uthe ukugcina amandla okukhiqiza anele bekulokhu kuyinkinga, kodwa i-TEP yenza kangcono kunabanye omakhelwane bayo besifunda.
Ukhulume nge-New Mexico Public Service Corporation, eyatshela abalawuli ukuthi ayinayo imali yokugcina amandla ngoJulayi noma ngo-Agasti.
I-New Mexico Public Service yanquma ngoFebhuwari ukugcina enye iyunithi yokukhiqiza amalahle esele eSan Juan isebenza kuze kube uSepthemba, izinyanga ezintathu ngemva kosuku lwayo lomhlalaphansi oluhleliwe, ukuze kwandiswe isilinganiso sayo sokugcina sasehlobo.
I-TEP iphinde isebenze ohlelweni lokuphendula isidingo lapho amakhasimende evumela izinsizakusebenza ukuthi zinciphise ukusetshenziswa kukagesi ngezikhathi ezimatasa ukuze kugwenywe ukushoda, kusho uBarrios.
UBarrios uthe le nkampani manje ingasebenzisana namakhasimende ezentengiselwano nawezimboni ukuze inciphise ngokushesha isidingo ngama-megawatts angu-40, futhi kukhona uhlelo olusha lokuhlola oluvumela abanye abahlali basefulethini ukuthi bathole isikweletu sebhili sekota esingu-$10 ukuze banciphise isidingo. Ukusetshenziswa kwabo kwesifudumezi samanzi kusukela phezulu.
Le nkampani iphinde ibambisane neTucson Water emkhankasweni omusha othi “Beat the Peak” ukunxusa amakhasimende ukuthi anciphise ukusetshenziswa kwamandla ngezikhathi ezimatasa, okuvame ukuba phakathi kuka-3 no-7 ntambama ehlobo, kusho uBarrios.
Umkhankaso uzohlanganisa okuthunyelwe ezinkundleni zokuxhumana kanye namavidiyo okumema amakhasimende ukuthi ahlole izinhlelo zamanani kanye nezinketho zokusebenzisa kahle amandla ukusiza ekunciphiseni ukusetshenziswa kwamahora aphezulu, esho.
