Amandla elanga adudula iningi lemikhumbi yamalahle yaseTexas esele ungaxhunyiwe ku-inthanethi: IEEFA

Ukwanda kwenani le-solar entsha kukulungele ukusunduza imikhumbi eminingi ephehlwa ngamalahle e-Texas ukuthi ithathe umhlalaphansi eminyakeni embalwa ezayo, ngokombiko we-Institute for Energy Economics and Financial Analysis (IEEFA).

Ucwaningo luchaza ukuba sengozini okwandayo kwezitshalo zamalahle kuyo yonke imakethe yokuphehla ugesi ephethwe yi-Electricity Reliability Council of Texas (ERCOT), indawo ehlanganisa iningi lesifunda.Ibona ngaphezulu kwama-70% esizukulwane esibaswa ngamalahle emini kwa-ERCOT sisengozini ngo-2022.

Ngokusho kwe-IEEFA, isizukulwane esisebenza ngomoya sibeke isiteji sokukhuphuka kwe-solar-scale-scale, empeleni siletha i-punch eyodwa-two emikhumbi yamalahle engaphansi kwezitshalo ezingu-11 futhi izoba yishumi ngo-Okthoba.

“Ukuphehlwa kwamandla kagesi ngamalahle e-Texas, ngenxa yomoya ohlanzekile, ongenawo izindleko zikaphethiloli kule minyaka eyishumi edlule, sekuzohlaselwa igagasi lesibili lokuncintisana okuvela ezintweni ezivuselelekayo njengoba amandla elanga esikalini esikalini ezama ukuthola isabelo esibalulekile semakethe. eminyakeni embalwa ezayo,” kusho uDennis Wamsted, umhlaziyi we-IEEFA nombhali oholayo walo mbiko.

Wengeze ngokuthi nakuba amandla elanga afakiwe e-US akhule cishe ngo-4,000% kule minyaka eyishumi edlule, izinga lokukhula kwawo kuyo yonke i-ERCOT liye lashesha nakakhulu, amandla afakiwe akhuphuka esuka ku-15MW ngo-2010 kuya ku-2,281MW ekupheleni kuka-2019. , ukwanda ngo-15,107%.Umthamo ofakiwe we-ERCOT ungakhuphuka ngenani eliqhathanisekayo kulo nyaka, ngokuqagela kwamanje okukhombisa ukuphakama kwelanga okungu-5.8GW ekupheleni kuka-2020.

Umbiko uphetha ngokuthi ukuqoqwa kokusetshenziswa kwamandla elanga kuzoshintsha ngendlela engenakuhlehliswa imakethe yansuku zonke futhi kuqhube izitshalo eziningi zamalahle zingaxhunyiwe ku-inthanethi ngo-2025.

“NgoJuni, ngokwesibonelo, ukuphehlwa kukagesi welanga kuhlinzeke ngo-4-5% wesidingo sikagesi wasemini izikhathi eziningi,” kusho umbiko.“Uma kubhekwa izindleko zayo eziphansi futhi uma kubhekwa imodeli yebhizinisi lamandla kuphela egridi yaseTexas, ekhokhela ugesi okhiqizwayo esikhundleni somthamo wokuphehla nje, amandla elanga ayakhula – futhi azoqhubeka nokuzuza – isabelo semakethe.Lokhu kuzoza ngezindleko zesizukulwane esibiza kakhulu, okungenzeka ukuthi sishiswe ngamalahle, esizoxhaswa ekuxubeni kwesizukulwane se-ERCOT ngenani eliqhathanisekayo. "

Umbiko ugcizelela ukubaluleka kokukhuphuka kobuchwepheshe bokugcinwa kwebhethri, obuthuthukayo ngokushesha futhi obamukelwa inani elikhulayo lezinsiza kanye nabakhiqizi bamandla abazimele.

Ukushicilelwa kwalo mbiko kuza ngesonto ngemuva kokuthi umthuthukisi welanga nesitoreji i-8minute Solar Energy ememezele ukuphothulwa kwephrojekthi yakhe yokuqala yesilinganiso sokusetshenziswa kwelanga eTexas.Ipulazi lelanga laseHolstein elingu-280MWdc/200MWdc, elakhiwe eduze kweDuke Energy Renewables, liphawula “ingqophamlando ebalulekile” imizuzu engu-8, kusho inkampani.

Imizuzu engu-8 njengamanje inamanye amaphrojekthi amane asekugcineni kwentuthuko esifundazweni i-Lone Star, emele amandla acishe abe ngu-1GW.U-Tom Buttgenbach, umongameli kanye ne-CEO ye-8minute, uthe inkampani iletha ubuchwepheshe bayo bokuthuthukisa i-solar kanye nesitoreji ukuze "benze imodeli entsha yamandla e-Texas".
