Kafukufuku watsopano wochokera ku Cornwall Insight apeza kuti mafamu a solar-scale a grid akulipira 10-20% yamtengo wopereka chithandizo pafupipafupi ku National Electricity Market, ngakhale pakali pano akupanga pafupifupi 3% ya mphamvu mu dongosolo.
Sikophweka kukhala wobiriwira.Ntchito za dzuwaali paziwopsezo zambiri kuti abwerere pazachuma - FCAS pakati pawo.
Kuchepetsa, kuchedwetsa kulumikizidwa, kutayika kwapang'onopang'ono, kuperewera kwa njira yotumizira magetsi, Federal Energy-policy vacuum yomwe ikupitilira - mndandanda wamalingaliro ndi zomwe zingasokoneze zomwe wopanga ma solar akukulira.Kuwerengera kwatsopano kochitidwa ndi akatswiri amagetsi a Cornwall Insight tsopano apeza kuti mafamu oyendera dzuwa akunyamula mopanda malire mtengo womwe ukukula wopereka ma frequency control ancillary services (FCAS) mu National Electricity Market (NEM).
Cornwall Insight ikuti minda yoyendera dzuwa imalipira pakati pa 10% ndi 20% yamitengo yonse ya FCAS mwezi uliwonse, pomwe pakadali pano amangotulutsa pafupifupi 3% yamagetsi opangidwa mu NEM.Poyerekeza, mafamu amphepo adapereka mphamvu zokwana 9% mu NEM mchaka chandalama cha 2019-20 (FY20), ndipo omwe adalipira FCAS adafika pafupifupi 10% yamitengo yonse.
"Zomwe zimalipira" zimatanthawuza kuchuluka kwa jenereta iliyonse yomwe imapatuka panjira yake kuti ikwaniritse cholinga chawo chotumizira mphamvu nthawi iliyonse yotumiza.
"Kuganizira kwatsopano pazantchito zongowonjezwdwa ndi udindo womwe mitengo yamitengo ya FCAS imadzetsa phindu la mapulojekiti amphamvu omwe angawonjezeke mtsogolo," akutero Ben Cerini, Principal Consultant ku Cornwall Insight Australia.
Kafukufuku wa kampaniyo adapeza kuti woyambitsa FCAS amalipira ndalama zama jenereta a solar a grid-scale ndi pafupifupi $2,368 per megawati chaka chilichonse, kapena pafupifupi $1.55/MWh, ngakhale izi zimasiyana m'magawo onse a NEM, ndi minda ya dzuwa ya Queensland yokhala ndi zoyambitsa zambiri mu FY20 kuposa zomwe kubadwa m'mayiko ena.
Cerini akuti, "Kuyambira 2018, malamulo a FCAS asintha pakati pa $ 10- $ 40 miliyoni kotala.Q2 ya 2020 inali kotala yaying'ono poyerekezera posachedwapa, pa $ 15 miliyoni ndi magawo atatu omaliza asanakwane $ 35 miliyoni kotala.
Nkhawa zopatukana zimafika poipa
Kutumiza kwa FCAS kumalola Australian Energy Market Operator (AEMO) kuti azitha kuyendetsa zopatuka pakupanga kapena katundu.Zomwe zimathandizira kwambiri pamtengo wapamwamba kwambiri wa FCAS wa Q1 chaka chino zinali zochitika zitatu zosayembekezereka "zopatukana": pamene mizere yambiri yopatsirana kum'mwera kwa NSW inagwedezeka chifukwa cha moto wa nkhalango, kulekanitsa kumpoto kuchokera kumadera akumwera kwa NEM pa 4 January;kulekanitsa kokwera mtengo kwambiri, pamene South Australia ndi Victoria anaikidwa pachilumba kwa masiku 18 kutsatira mkuntho umene unayimitsa njira zotumizira mauthenga pa 31 January;ndi kulekanitsidwa kwa South Australia ndi kumadzulo kwa Victoria's Mortlake Power Station kuchokera ku NEM pa 2 March.
NEM imagwira ntchito ngati njira yolumikizira FCAS imatha kuchotsedwa mu gridi yonse, kulola AEMO kuyimbira zotsika mtengo kuchokera kwa othandizira monga ma jenereta, mabatire ndi katundu.Pazochitika zolekanitsa, FCAS iyenera kukhala yochokera kwanuko, ndipo pankhani ya kulekanitsidwa kwa masiku 18 kwa SA ndi Victoria, idakwaniritsidwa ndi kuchuluka kwamagetsi opangidwa ndi gasi.
Zotsatira zake, mtengo wamakina a NEM mu Q1 unali $310 miliyoni, pomwe ndalama zokwana $277 miliyoni zidakokedwa mpaka FCAS yofunikira kuti chitetezo cha grid chikhale chovuta kwambiri.
Kubwerera ku dongosolo lodziwika bwino kumawononga $ 63 miliyoni mu Q2, pomwe FCAS idapanga $ 45 miliyoni, "zidachitika makamaka chifukwa cha kusowa kwa zochitika zazikulu zolekanitsa magetsi", idatero AEMO mu Q2 2020 yake.Quarterly Energy Dynamicslipoti.
Ma solar akuluakulu amathandizira kuchepetsa mtengo wamagetsi wamba
Nthawi yomweyo, Q2 2020 idawona mitengo yamagetsi yamagawo onse ikufika pamiyezo yotsika kwambiri kuyambira 2015;ndi 48-68% kutsika kuposa momwe zinaliri mu Q2 2019. AEMO inatchula zinthu zomwe zathandizira kuchepetsa mitengo yamtengo wapatali monga: "kutsika mtengo wa gasi ndi malasha, kuchepetsa mavuto a malasha pa Mount Piper, kuchuluka kwa mvula (ndi kutulutsa madzi), ndi zatsopano. zongowonjezera”.
Kutulutsa kwamagetsi osinthika amtundu wa gridi (mphepo ndi solar) kudakwera ndi 454 MW mu Q2 2020, kuwerengera 13% ya zosakaniza, kuchokera pa 10% mu Q2 2019.
Mphamvu zongowonjezedwanso zotsika mtengo zidzangowonjezera zomwe zikuthandizira kuchepetsa mitengo yamagetsi yogulitsa;ndi ukonde wogawidwa ndi kulimbikitsidwa wotumizirana maulumikizidwe, pamodzi ndi malamulo okonzedwanso olamulira kulumikizidwa kwa batri mu NEM, ali ndi chinsinsi chotsimikizira mwayi wopezeka ku FCAS yamitengo yopikisana ngati pakufunika.
Pakalipano, Cerini akuti opanga ndi osunga ndalama akuyang'anitsitsa zoopsa zilizonse zomwe zingawononge ndalama za polojekiti: "Pamene mitengo yamtengo wapatali yatsika, nthawi yogula mphamvu yogula mphamvu yafupika, ndipo zinthu zowonongeka zasintha," akufotokoza.
Cornwall Insight yalengeza cholinga chake chopereka kulosera kwamitengo ya FCAS kuyambira Seputembara 2020, ngakhale mitundu yazomwe zidapangitsa kuti FCAS ichuluke mu Q1 ndizovuta kuziyembekezera.
Komabe, Cerini akuti, "Ngongole za FCAS tsopano zakhazikika pazoyenera kuchita."
