Inhlolovo ibonisa ukuthi ku-National Electricity Market (NEM), esebenzela ingxenye enkulu ye-Australia, amasistimu okugcina amabhethri adlala indima ebalulekile ekuhlinzekeni I-Frequency Controlled Ancillary Services (FCAS) kugridi ye-NEM.
Lokho ngokombiko wenhlolovo yekota eshicilelwe yi-Australian Energy Market Operator (AEMO). Uhlelo lwakamuva lwe-Australian Energy Market Operator's (AEMO) lwekota ye-Energy Dynamics Report luhlanganisa isikhathi sikaJanuwari 1 kuya kuMashi 31, 2022, olugqamisa intuthuko, izibalo namathrendi athinta i-Australia's National Electricity Market (NEM).
Ngokokuqala ngqa, ukugcinwa kwebhethri kwaba nesabelo esikhulu kunazo zonke sezinsizakalo zokulawula imvamisa ezinikeziwe, ngesabelo semakethe esingamaphesenti angu-31 kuzo zonke izimakethe eziyisishiyagalombili ezihlukene ezihambisana nokulawula imvamisa (i-FCAS) e-Australia. Amandla aphehlwa ngamalahle namandla aphehlwa ngamanzi kubambene endaweni yesibili ngo-21% lilinye.
Ngekota yokuqala yalo nyaka, imali engenayo ephelele yezinhlelo zokugcina amandla ebhethri e-Australia's National Electricity Market (NEM) ilinganiselwa cishe ku-A$12 million (US$8.3 million), okuwukunyuka kwama-200 uma kuqhathaniswa ne-A$10 million engxenyeni yokuqala ka-2021. amaRandi ayizigidi zase-Australia. Nakuba lokhu kwehlile uma kuqhathaniswa nemali engenayo ngemva kwekota yokuqala yonyaka odlule, ukuqhathaniswa kwekota efanayo unyaka ngamunye kungenzeka kube okufanelekile ngenxa yenkathi yamaphethini wokufunwa kukagesi.
Ngasikhathi sinye, izindleko zokuhlinzeka ngokulawulwa kwemvamisa zehle zaba cishe izigidi ezingama-A $43, cishe ingxenye eyodwa kwezintathu yezindleko ezirekhodwe engxenyeni yesibili, yesithathu neyesine ka-2021, futhi cishe zifana nezindleko ezirekhodwe kwikota yokuqala ka-2021 efanayo. Kodwa-ke, ukwehla kwakungenxa yokuthuthukiswa kwesistimu yokudlulisela yase-Queensland, okubangele amanani aphezulu e-Frequency Control Ancillary Services (FCAS) ngesikhathi sokuphazamiseka kombuso okuhleliwe ezingxenyeni ezintathu zokuqala.
I-Australian Energy Market Operator (AEMO) iveza ukuthi nakuba isitoreji samandla ebhethri sibambe indawo ephezulu emakethe ye-Frequency Controlled Ancillary Ancillary Services (FCAS), eminye imithombo emisha ngokuqhathaniswa yokulawulwa kwamafrikhwensi njengokuphendula kwesidingo kanye nezitshalo zamandla abonakalayo (VPPs) nazo seziqala ukudla. isabelo esihlinzekwa ukuphehlwa kwamandla okujwayelekile.
Amasistimu okugcina amandla ebhethri awasetshenziselwa ukugcina ugesi kuphela kodwa nasekuphehleni ugesi.
Mhlawumbe into enkulu ethathwe embonini yokugcina amandla ukuthi ingxenye yemali engenayo evela ku-Frequency Controlled Ancillary Services (FCAS) empeleni yehla ngesikhathi esifanayo nenzuzo evela ezimakethe zamandla.
I-Frequency Controlled Ancillary Services (FCAS) ibe yinkampani ekhiqiza imali ephezulu kakhulu yezinhlelo zokugcina amabhethri eminyakeni embalwa edlule, kuyilapho izinhlelo zokusebenza zamandla njenge-arbitrage zisalele emuva kakhulu. Ngokuka-Ben Cerini, umeluleki wabaphathi wefemu yocwaningo lwemakethe yamandla i-Cornwall Insight Australia, cishe u-80% kuya ku-90% wemali engenayo yezinhlelo zokugcina amabhethri ivela kumasevisi okulawula i-frequency ancillary services (FCAS), futhi cishe u-10% kuya ku-20% uvela ekuhwebeni kwamandla.
Kodwa-ke, kwikota yokuqala ka-2022, i-Australian Energy Market Operator (AEMO) ithole ukuthi ingxenye yesamba semali engenayo ethathwe izinhlelo zokugcinwa kwamabhethri emakethe yamandla yeqe yaya ku-49% isuka ku-24% kwikota yokuqala ka-2021.
Amaphrojekthi amasha amaningana amakhulu okugcina amandla aqhubekisele lokhu kukhula kwesabelo, njengebhethri Enkulu ye-Victorian engu-300MW/450MWh esebenza e-Victoria kanye nesistimu yokugcina ibhethri engu-50MW/75MWh Wallgrove e-Sydney, NSW.
I-Australian Energy Market Operator (AEMO) iphawule ukuthi inani le-arbitrage enesisindo somthamo likhuphuke lisuka ku-A$18/MWh laya ku-A$95/MWh uma liqhathaniswa nekota yokuqala ka-2021.
Lokhu kugqugquzelwe kakhulu ukusebenza kwesiteshi sikagesi sase-Queensland, i-Wivenhoe, esithole imali eyengeziwe ngenxa yokuntengantenga kwenani likagesi kuhulumeni ngekota yokuqala ka-2021. Lesi sikhungo sibone ukwanda ngo-551% kokusetshenziswa kuqhathaniswa nekota yokuqala ka-2021 futhi sikwazile ukukhiqiza imali ngezinye izikhathi engaphezu kuka-A$300/MW. Izinsuku ezintathu nje zokuguquguquka kwamanani entengo kuzuze lesi sikhungo u-74% wemali engenayo yekota.
Abashayeli bezimakethe eziyisisekelo basho ukukhula okuqinile kumthamo wokugcina amandla e-Australia. Isikhungo sokuqala sezwe esisha esidonsa amanzi eminyakeni engaba ngu-40 siyakhiwa, futhi kungenzeka kulandele izinsiza ezengeziwe zikagesi ezimpontshwa. Kodwa-ke, imakethe yemboni yokugcina amandla ebhethri kulindeleke ukuthi ikhule ngokushesha.
Ibhethriuhlelo lokugcina amandla oluzothatha indawo yezindawo zokuphehla amandla kagesi ngamalahle ku-NSW lugunyaziwe.
I-Australian Energy Market Operator (AEMO) ithe nakuba manje sekuno-611MW wezinhlelo zokugcina amabhethri ezisebenza e-Australia's National Electricity Market (NEM), kukhona u-26,790MW wamaphrojekthi okugcina amabhethri ahlongozwayo.
Enye yalezi iphrojekthi ye-Eraring yokugcina ibhethri e-NSW, iphrojekthi yokugcina ibhethri engu-700MW/2,800MWh ehlongozwa umthengisi omkhulu wamandla odidiyelwe kanye nejeneretha ye-Origin Energy.
Le phrojekthi izokwakhiwa endaweni yesikhungo sikagesi esisebenza ngamalahle se-Origin Energy sika-2,880MW, inkampani enethemba lokuthi izoyeka ukusebenza ngo-2025. Iqhaza layo ekuhlanganiseni kwamandla endawo izothathelwa indawo indawo yokugcina amandla ebhethri kanye nesikhungo samandla esibonakalayo esihlanganisiwe esingu-2GW, esihlanganisa indawo ekhona ye-Origin yokuphehla ugesi oshisayo.
I-Origin Energy iveza ukuthi esakhiweni semakethe esithuthukayo se-Australia's National Electricity Market (NEM), izimboni zamandla kagesi ngamalahle zithathelwa indawo izinto ezivuselelekayo, izinhlelo zokugcina amandla kanye nobunye ubuchwepheshe besimanje.
Le nkampani isimemezele ukuthi uMnyango Wezokuhlela Nezemvelo kahulumeni we-NSW ugunyaze izinhlelo zephrojekthi yawo yokugcina amandla ebhethri, okuwenza ube mkhulu kunawo wonke e-Australia.
