Ababhidi bomjikelezo wokuqala abakhethiwe ukuthi baqhubekele esigabeni sesibili bathola izimemo zokuhambisa iziphakamiso zobuchwepheshe ezinemininingwane nokusekelwa okuphelele kobunjiniyela.
Le ndlela yesiteji yehlisa umthwalo wokuhlola kuyilapho iqinisekisa ukuthi iziphakamiso zokugcina zifaka imininingwane ephelele yezobuchwepheshe. Ukuthengwa kwe-Massachusetts's 1,500 MW BESS ngo-2025 kwasebenzisa lesi sakhiwo, kwazisa abakhethiwe oyedwa ezinyangeni ezintathu ngemuva kokuthunyelwa kokuqala futhi kwavumela ezinye izinyanga ezintathu ngeziphakamiso ezinemininingwane emizuliswaneni emibili.
Amanye Amamodeli Wokuhlangana
Akuwona wonke amaphrojekthi adinga ama-RFP asemthethweni. Amaphrojekthi amancane noma lawo anezidingo ezithile zobuchwepheshe angase azuze ekuzibandakanyeni ngokuqondile nomkhiqizi. Le ndlela isebenza uma uhlonze abakhiqizi abathize amakhono abo obuchwepheshe noma ubukhona bendawo buhambisana nezidingo zephrojekthi.
Ukusebenzelana okuqondile nakho kufanela amaphrojekthi adinga izikhathi ezisheshayo zokwenziwa. Ama-RFP asemthethweni engeza izinyanga ezi-3 kuya kwezingu-6 ezinhlelweni zokuthenga, okungenzeka kungamukeleki-ekulandeleni intuthuko esheshayo noma amaphrojekthi angena esikhundleni anezinsuku zokugcina eziqinile.
Amafulegi Abomvu Ngesikhathi Sokuhlanganyela Umkhiqizi
Izibopho Zokulethwa Ezingacacile
Abakhiqizi abahloniphekile bahlinzeka ngezikhathi ezithile zokuhola ngedethi ecacile yengqophamlando. Qaphela abakhiqizi abanikeza izithembiso zokulethwa "ngokushesha ngangokunokwenzeka" ngaphandle kwamashejuli okukhiqiza anemininingwane. Ukubambezeleka kwezisetshenziswa kumela imbangela eyinhloko yokushelela kweshejuli yephrojekthi ye-BESS.
Cela amadokhumenti amandla okukhiqiza abonisa izindawo zokukhiqiza ezitholakalayo. Abakhiqizi abakhulu bagcina izincwadi zoku-oda izinyanga eziyi-12 kuye kweziyi-18 ziphumile, futhi iphrojekthi yakho kufanele ibe nokuma okucacile kulo mugqa. Ngaphandle kokwabiwa kwamandla okubhaliwe, izithembiso zokulethwa azikho ukwethembeka.
Ukusekela Okulinganiselwe Kwezobuchwepheshe
Abakhiqizi kufanele banikeze izinsiza zobunjiniyela ukuze basekele ukuthuthukiswa kwephrojekthi. Lokhu kubandakanya ukubamba iqhaza ezimpendulweni zocwaningo lokuxhumanisa, ukubuyekeza imiklamo kagesi yesayithi, nokusiza ekulungiseleleni izilungiselelo zesistimu. Abakhiqizi abanikeza izingcaphuno zamanani kuphela ngaphandle kokusebenzelana kobuchwepheshe kungenzeka bantula ukujula kobuchwepheshe obudingekayo ukuze kwenziwe ngempumelelo iphrojekthi.
Ukwesekwa kwezobuchwepheshe kuba semqoka kakhulu ngesikhathi sesigaba sokugunyazwa. Abakhiqizi kufanele bazibophezele-ekusekeleni kusayithi phakathi nokuqaliswa kwesistimu, banikeze ukuqeqeshwa kwezisebenzi zokusebenza, futhi banikeze izindlela ezicacile zokukhuphuka zezinkinga zobuchwepheshe. Lezi zibopho kufanele zivele ezinkontilekeni, hhayi nje izithembiso zomlomo.
Imininingwane Yesiqinisekiso Enganele
Izakhiwo zewaranti zamaphrojekthi we-BESS ziyahlukahluka kakhulu kubo bonke abakhiqizi futhi zinomthelela oqondile wezomnotho wephrojekthi. Iziqinisekiso ezijwayelekile ziqinisekisa u-70% kuya ku-80% umthamo osele ngemva kweminyaka eyi-10, kodwa izimo ezixhunywe kulezi ziqinisekiso zibaluleke kakhulu.
Hlola ukukhishwa kwewaranti ngokucophelela. Abanye abakhiqizi bawacima amawaranti uma amasistimu edlula izibalo zomjikelezo wonyaka othile noma esebenza ngaphandle kwamazinga okushisa achaziwe. Ezinye zinikeza-iziqinisekiso ezisuselwe ekusebenzeni (akalwa ngo-MWh wamandla ajikelezisiwe) aqondana kangcono nokusetshenziswa kwesistimu kwangempela. Le mininingwane inquma ukuthi iziqinisekiso zinikeza ukuvikeleka okunengqondo noma zikhona ngokwezinjongo zokumaketha.
imibuzo ejwayelekile ukubuzwa
Ingabe insiza{0}}ikala amaphrojekthi we-BESS kusenesikhathi kangakanani ukuvikela abahlinzeki bempahla?
Amaphrojekthi wensiza-avikela abahlinzeki bezinto zokusebenza izinyanga eziyi-12 kuya kweziyi-18 ngaphambi kwedethi yokulethwa edingekayo, ukubalwa kwezikhathi ezihamba phambili zokukhiqiza zamaviki angu-12 kuya kwangu-16 kanye nemijikelezo yokuthenga enwetshiwe yebhalansi ende{6}ehamba phambili{6}ye{7}yezingxenye zesistimu. Ama-Transformer awodwa angase adinge izinyanga ezingama-32 kuye kwezingama-36 kusukela eku-odweni kuye ekulethweni ngokuya ngedatha yemboni yango-2023, nakuba amabhethri ngokwawo enezikhathi ezibikezelwayo.
Ngingakwazi ukubandakanya abakhiqizi ngaphambi kokuqeda izifundo zokuxhumanisa?
Yebo, ukusebenzelana komkhiqizi kokuqala kunengqondo uma usunokulawula isayithi kanye nemiphumela yokuqala yocwaningo lokuxhumanisa. Abakhiqizi banikeza okokufaka kobuchwepheshe okubalulekile phakathi nenqubo yokuxhumanisa, okusiza ukuthuthukisa ukulungiselelwa kwesistimu ngokusekelwe kuzithiyo zokuxhuma kugridi. Kodwa-ke, gwema izibopho ezisemthethweni zokuthengwa kwempahla kuze kube yilapho kutholakala khona ukuxhumeka okuqinisekile ngokuphusile.
Kwenzekani uma ngixhumana nabakhiqizi kusenesikhathi kakhulu ekuthuthukisweni kwephrojekthi?
Ukusebenzelana komkhiqizi ngaphambi kwesikhathi kusaphaza izinsiza nhlangothi zombili. Ngaphandle kwezidingo eziqinile zobuchwepheshe, idatha yesayithi, noma imiphumela yocwaningo lokuxhumanisa, abakhiqizi banganikeza kuphela ulwazi olujwayelekile okungenzeka lungasebenzi kuphrojekthi yakho yangempela. Linda uze uqedele ukuhlaziya ukuthi kungenzeka yini isayithi futhi ube nemiphumela yocwaningo lokuxhumanisa lokuqala ngaphambi kokuqala izingxoxo zomkhiqizi.
Ingabe abakhiqizi bakhokhisa imali yeziphakamiso zobuchwepheshe kanye nokwesekwa kobunjiniyela?
Abakhiqizi abaningi bahlinzeka ngeziphakamiso zokuqala zobuchwepheshe kanye nokusekelwa okuyisisekelo kobunjiniyela njengengxenye yenqubo yabo yokuthengisa ejwayelekile. Kodwa-ke, umsebenzi wobunjiniyela owenziwe ngokwezifiso onemininingwane (ofana nokumodela okuphelele okushisayo noma izifundo zokuhlanganisa okukhethekile) ungathola izinkokhelo. Thola ukuthi usekelo lobunjiniyela lufakiwe yini noma lukhokhiswa ngokwehlukana phakathi nezingxoxo zokuqala ukuze ugweme ukungezwani.
Ukuqhubekela Phambili Ngephrojekthi Yakho ye-BESS
Abakhiqizi obakhethayo baba ozakwethu-besikhathi eside phakathi nokuthuthukiswa kwephrojekthi, ukwakhiwa, nokusebenza. Khetha isikhathi esinikeza abakhiqizi isaziso esanele ngenkathi uqinisekisa ukuthi unolwazi olwanele ukuze wenze izinqumo ezihlakaniphile. Kumaphrojekthi amaningi, le ndawo emnandi yenzeka ezinyangeni eziyi-12 kuya kweziyi-18 ngaphambi kokusebenza kwezentengiso lapho imininingwane yobuchwepheshe isiphelele kakhulu kodwa ukuguquguquka okwanele kusasele kubakhiqizi ukuthi banikele ngeziphakamiso eziphusile zokuthuthukisa.
Landelela inqubekelaphambili yakho yokuxhumana, umugqa wesikhathi wokuxhasa ngezimali, neshejuli yokwakha ngokumelene nezidingo zesikhathi sokuhola komkhiqizi. Dala ingqophamlando yangaphakathi yokusebenzelana komkhiqizi ehlanganisa ubunkimbinkimbi nesikali esikhethekile sephrojekthi yakho. Amaphrojekthi aqondanisa ngokuhlelekile isikhathi sokusebenzisana komkhiqizi nokulungela kwezobuchwepheshe nezohwebo athola imiphumela engcono ngokuqhubekayo kunalawo asheshisa ukuthengwa kwempahla noma abambezele izinqumo zemishini kuze kube yilapho ingcindezi yesikhathi iphoqelela ukuyekethisa.
