I-Solar-Plus-Isitoreji Ibusa Igridi Yamandla Yesikhathi Esizayo

Umbiko omusha ovela eMnyangweni Wezamandla wase-US (DoE) uLawrence Berkeley National Laboratory ubonisa ukwanda okukhulu kwezindawo zokugcina i-solar-plus-storage emakethe yokuphehla ugesi yase-US.

Ngaphakathi kwe-United States, idatha evela ku-Lawrence Berkeley National Laboratory's energy market and policy team (EMP) ikhombisa ukuthi njengamanje kunezimboni zamandla ayingxube ezingama-469 ezisebenzayo e-United States.

Cishe u-61% wezitshalo eziyingxubevange, noma izikhungo ezingama-288, zingamaphrojekthi we-solar-plus-storage. Lezi zitshalo zimelela iningi lomthamo wokugcina amandla, ngo-7.8 GW kanye no-24.2 GWh wamandla asetshenziswe ezweni lonke. Ngo-2023, amaphrojekthi amasha angama-66 kwangu-80 bekuyizinhlelo ze-PV-plus-storage.

I-“Hybrid Power Plants: Status of Operating and Proposed Plants Edition 2024” ithatha idatha evela ku-US DoE's Energy Information Administration (EIA), kanye nemibiko yaminyaka yonke ngolayini bokuxhumana besizwe.

Ukwandiswa kwezindawo zokugcina i-solar-plus-storage kwathola umfutho ngo-2020, ekuqaleni kuqhutshwa amaphrojekthi amancane eMassachusetts. Lo mkhuba uthuthukiswe yi-California, Texas kanye neFlorida, lapho ukwethulwa kwezikhungo ezinkulu kukhulise kakhulu umthamo wonkana. Ngokuphawulekayo, iMassachusetts isingatha izindawo zokugcina zelanga ezingama-89 zezwe ezingama-288, ngasinye sinomthamo ongaphansi kuka-7 MW. Lokhu kufakwa kukhuthazwa uhlelo lwezwe lwe-SMART, oluthuthukisa ukugcinwa kwamandla ngezilinganiso ezinenzuzo ze-DC kuya ku-AC nokuhlanganiswa kwebhethri.

I-California ilandela njengezwe elinenombolo yesibili ephezulu yezindawo zokugcina ilanga nelanga, isamba esingu-72. Ngokungafani neMassachusetts, cishe ingxenye yalezi zikhungo zaseNtshonalanga idlula i-100 MW yomthamo welanga. I-Arizona ne-California zihamba phambili ngenani lezitshalo eziyingxube ezintsha ze-solar-plus-storage, ezinezindawo ezintsha eziyi-15 nezingu-16 eziza ku-inthanethi, ngokulandelana.

Ukusetshenziswa kwezitshalo kuyashintsha, kokubili jikelele futhi ngezinye izikhathi ngazinye. Kube nokuguquguquka kuzwelonke kusukela ekusebenziseni ngokuyinhloko isitoreji samandla ukulawulwa kwemvamisa kuya ekusetshenzisweni kakhulu kwe-arbitrage, okuhambisana nokuncishiswa okukhulayo kwezinsiza zelanga. Lokhu kubaluleke kakhulu ezitshalweni zamandla elanga lapho ukugcinwa kusiza ukuthwebula amandla okungenzeka ancishiswe ngenye indlela futhi kuzinzise iphrofayili yokukhiqiza yezinsiza zelanga.

Umbiko we-EMP uhlanganisa izifundo zezibonelo zezitshalo zamandla ezingazodwana, okuhlanganisa i-Blythe Solar II kanye ne-Meyersdale Windpower, nedatha yokusebenza enemininingwane eboniswe kumagrafu angezansi. I-Blythe Solar II, imboni yelanga engu-131 MW (AC) ene-115 MW/528 MWh yokugcina, yengeze indawo yokugcina ngo-2021 engqalasizinda yayo yelanga ka-2016. Isikhungo sijikelezisa amabhethri aso ngaphansi kokukodwa ngosuku, siqondanise lokhu namahora aphezulu elanga kanye nesidingo sakusihlwa sokuxazululwa kwamandla okufana nentengo ye-CAISO ye-wholesale kanye nokushintshwa kwelanga. Kodwa-ke, i-EIA ibala ukulawulwa kwemvamisa njengomsebenzi oyinhloko wesitshalo, kanye ne-arbitrage njengokwesibili.

I-Meyersdale Windpower, indawo yomoya engu-30 MW enebhethri engu-18 MW/12.1 MWh engezwe ngo-2015, isebenza ngendlela ehlukile kune-Blythe. Ibhethri layo lijikeleza ngokwesilinganiso izikhathi eziyisithupha ngosuku, futhi kufika izikhathi eziyishumi nambili ngaphansi kwezimo ezithile. I-EIA ihlonza ukulawulwa kwamafrikhwensi njengomsebenzi oyinhloko nowodwa webhethri le-Meyersdale, oqondana nokuhamba kwayo njalo ngamabhayisikili.

Ukuqhubekela phambili, umthamo uhlanzekile futhi uhambisana nesitoreji.

E-California, imakethe ye-solar esikalini esisetshenziswayo isiguquke ngempumelelo yaba imakethe ye-solar-plus-storage, cishe wonke amaphrojekthi amasha anezinhlelo ezixubile. Umkhakha we-PV wezindawo zokuhlala nawo uyakhula, ngenani lokunamathiselwe kwisitoreji esingu-60%.

Umbiko uthe imigqa kazwelonke yokuxhumana ibheke kumodeli yesikhungo samandla ayingxube yaseCalifornia. Njengamanje, u-47% womthamo wesikhathi esizayo uhlelelwe njengezitshalo eziyingxube, kanti u-92% uyindawo yokugcina amandla elanga nelanga. Engqikithini engu-2.5 TW emgqeni, ama-2 TW okucushwa kwelanga nesitoreji, kungaba okuzimele noma okuxubile, okubonisa ikusasa elibuswa yibo lobu buchwepheshe.

Izitayela zamanani esikhathi esizayo zesitoreji samandla, ezibone ukwehla okukhulu futhi okulindeleke ukuthi ziqhubeke, zishayela lokhu kuthunyelwa komugqa wokuxhuma. Ngo-2024, ukutshalwa kwezimali ku-solar kulindeleke ukuthi kudlule ama-dollar ayizigidi eziyizinkulungwane ezingama-500, okuqinisekisa ukukhula kwezindawo zokugcina i-solar-plus-storage ngezindleko eziphansi ze-hardware kanye nokusebenza okuthuthukisiwe kwemojula yelanga.

Kodwa-ke, esikhathini esifushane, amanani entengo yezindawo zokugcina i-solar-plus-yenyuka kancane.

Ithimba le-EMP lihlaziye idatha yentengo evela ezivumelwaneni zokuthenga amandla elanga kanye nesitoreji eziyi-105, ezimele u-13 GW welanga kanye no-7.8 GW/30.9 GWh wendawo yokugcina amandla. Intengo yezinhlelo ezihlanganisiwe inyukile kusukela ngo-2020, ngokwengxenye ngenxa yamandla okugcina amabhethri aphezulu, aqhutshwa yizindleko zamahora engeziwe okugcina i-lithium. Nakuba ukuhluka kokusetshenziswa kwebhethri kwenza ukuhlaziya kube nzima, ukwehla kwamandla emali e-supply chain nakho kube nomthelela ekwenyukeni kwentengo.

Naphezu kwalezi zindleko ezikhulayo, inani elikhulayo lamaphrojekthi amasha okugcina amandla abonisa ukuthi imakethe ihlala iqinile, amandla aqhubeka nokukhula.
