Mutambi mutsva ari kutora nhanho mumusika weCalifornia magetsi wakachajiswa.Pinda lithium-ion simba rekuchengetedza.
Nyika yakaona shanduko iyi ichiuya makore apfuura, asi kukurumidza kwanga kuchikwira kubva muzhizha ra2019, apo maCalifornia regulators uye zvishandiso zvinotanga.kufanotaura kuperevedza kweawa yepamusoro munaGunyana 2020.
Vatongi vacho vakaona kuti "nguva yepamusoro ye[kudiwa kwemagetsi] mugore inoitika nguva dzose munaGunyana… mukati meawa inopera 17 (zvichienderana nePST kana 6:00 pm PDT).Pakazosvika 2022, nhamba yepamusoro inochinja kusvika paawa inopera 18. "
Sezvatinoona muchati (uye yakacherechedzwa nemabhokisi machena anotsanangurwa se "uncontracted imports"), kune maawa matatu kusvika mana apo vatongi vanofanotaura kuperevedza.
Muna 2020, kushomeka uku kwakasvika zviuru zvitanhatu MWh kwemaawa matatu.Muna 2021, vatongi vakawedzera awa uye vakawedzera huwandu hwekushomeka mukati meimwe neimwe yeawa hwindo, zvichiunza kushomeka kwese ku14,400 MWh.Nhamba iyoyo yakawedzera zvakare muna 2021 kusvika 15,400 MWh ye "simba rakashaikwa" kwemaawa mana.
Kugadzirisa kushomeka (uye kubhadharira gwenya remagetsi enyukireya rava kuda kuvhara), California nguva pfupi yadarika yakafunga kudaroprocure11.5 GW yesimba rakachena rinowanikwa resource kukwana ne 2026. Izvozvo zvinomiririra simba rekukurumidza, nhamba iyo yakawanda yemagetsi ekuchengetedza magetsi inofanira kuchengetedza kwemaawa mashoma mana.
Kutenga uku kunoda imwe muzana yesimba rakachena kuti riwanikwe sekuchengetedza kwenguva refu, kwemaawa angangoita gumi.Izvo zvinogona kududzira kune inodarika 60 GWh yekuchengetedza simba rakachena yakawedzerwa kune grid muhafu yegumi inotevera.
Ndiko kuwanda kwesimba rekuchengetedza mune ramangwana reCalifornia.Asi sezvo masayendisiti emamiriro ekunze ari kuwedzera kuridza aramu pamusoro pemoto wakakonzerwa nekusanaya kwemvura muCalifornia, pfungwa iri kuwedzera yekukurumidzira iripo.
Neraki, zviuru zviviri zveMW yesimba rekuchengetedza simba iri kuuya online naNyamavhuvhu 1, maererano neCalifornia Public Utility Commission.Yakawanda yeiyi simba ichave nemaawa mana ebhatiri simba rakagara kumashure kwayo, ingangoita 8,000 MWh yakazara.
Setarisiro yezvipi izvo chiyero chinopihwa, isu tiri kuwana yedu yekutanga kuona kuburikidza neCalifornia ISO Supply machati.
Musi waChikunguru 9 na6:30 PM, grid hombe yeCalifornia yakataura kuti kuchengetedza kwesimba kwakapinza 999 MW yesimba panguva ye "flex chiitiko" apo kudzimwa kwemagetsi kungave kwakaitika neimwe nzira.
Ziva nguva dzekuchaja bhatiri, pano futi.Sezvo simba rezuva rezuva reCalifornia richikura, kuchengetedza kwesimba kunowedzera kugadzirisa magetsi akachipa kusvika padanho rekuchengetedza simba rinogona kuita nguva yemanheru.
Mumwe wemienzaniso yekutanga yechiitiko chikuru chekuchaja chakaitika munaChikunguru 14 na9:15 AM, uye yakaunzwa kwatiri neCalifornia energy data geek.Joe Deely.Hezvino zvazvaitaridza:
Ongororo yekudzokororwa kwemitengo yemagetsi panguva iyoyo inogona kutipa chiratidzo chekuti sei mabhatiri aya akasarudzwa kuchaja panguva ino.
Mabhatiri maviri epasi rose e-lithium ion akabatsira kune aya masimba, uye akatsigira grid panguva yechiitiko cheflex.
Yekutanga ndeye LS Power's230MW lithium ion simba rekuchengetedza nzvimbo, iyo yakarongwa kuti iwedzere kubva pa230MWh kusvika pa690MWh nezhizha rino, uye kuwedzera humwe huwandu pane imwe nguva inotevera.Ichi chirimwa, kwechinguva zvakadaro, chimwe chepasi rose che lithium ion grid akabatana mabhatiri.
Nzvimbo yechipiri ndeye Moss Landing's300 MW / 1,200 MWh nzvimbo- zvakare, imwe yehukuru munyika yose ikozvino - iyo yakabatana negridi muna December 2020. Iyi nzvimbo inogona kuwedzera nokukurumidza kusvika 1.5 GW / 6 GWh.
Tose ngatibatisisei, nekuti - kwete kure zvakanyanya mune ramangwana - tichaona 1.21 GW… Doc Brown's flux capacitor sarudzo.
