Tsvagiridzo nyowani kubva kuCornwall Insight inowana grid-scale solar mapurazi ari kubhadhara 10-20% yemutengo wekupa ma frequency ekuwedzera masevhisi kuNational Electricity Market, kunyangwe parizvino ari kugadzira inenge 3% yesimba muhurongwa.
Hazvisi nyore kuva girini.Mapurojekiti ezuvavari pasi penjodzi dzakawanda dzekudzoka pakudyara - FCAS pakati pavo.
Kudzora, kunonoka kwekubatanidza, kurasikirwa kwezvinhu, isina kukwana magetsi ekufambisa system, iyo inoenderera Federal simba-policy vacuum - runyorwa rwekufunga uye vangango kanganisa kubva kuzasi kwekuvandudza kwezuva kuri kuramba kuchiwedzera.Kuverengera kutsva nevaongorori vemagetsi Cornwall Insight ikozvino vanoona kuti mapurazi ezuva ari kukwira zvisingaite mutengo uri kukura wekupa frequency control ancillary services (FCAS) muNational Electricity Market (NEM).
Cornwall Insight inoshuma kuti mapurazi ezuva anobhadhara pakati pe10% ne20% yemitengo yakazara yeFCAS mumwedzi chero wakapihwa, apo panguva ino vanogadzira chete 3% yesimba rinogadzirwa muNEM.Tichienzanisa, mapurazi emhepo akapa chimwe chikamu che9% chesimba muNEM mukati megore rezvemari 2019-20 (FY20), uye mubhadharo wavo wakawedzerwa weFCAS wakabhadhara wakasvika pa10% yemitengo yese yemutemo.
Iyo "causer pay" inoreva kuti ingani chero jenareta inotsauka kubva kune yavo mutsara werampu mwero kuti isangane navo inotevera simba rekutumira tarisiro yenguva yega yega yekutumira.
"Kutariswa kutsva kwezvekushandisa patsva imhosva iyo mitengo yepamusoro yeFCAS inoisa kune pundutso yemapurojekiti emagetsi emagetsi azvino uye emangwana," anodaro Ben Cerini, Principal Consultant kuCornwall Insight Australia.
Tsvagiridzo yekambani iyi yakaona kuti FCAS inokonzeresa inobhadhara mari yegridi-scale solar jenareta inosvika $2,368 per megawatt gore rega, kana kutenderedza $1.55/MWh, kunyangwe izvi zvichisiyana mumatunhu eNEM, nemapurazi ezuva reQueensland ane akanyanya kukonzera anobhadhara zvinhu muFY20 kupfuura izvo. inozvarwa mune dzimwe nyika.
Cerini anoti, "Kubva 2018, mutemo weFCAS mutengo wachinja pakati pemadhora gumi- $40 miriyoni pakota.Q2 ye2020 yaive chikamu chidiki nekuenzanisa nguva pfupi yadarika, pamadhora gumi nemashanu nemakumi matatu ekupedzisira pasati yadarika madhora makumi matatu neshanu pakota. "
Kuzvidya mwoyo kwekuparadzana kunotora dambudziko rayo
Kuendesa FCAS kunobvumira iyo yeAustralia Energy Market Operator (AEMO) kugadzirisa kutsauka muchizvarwa kana mutoro.Vaya vakanyanya kupa mari yepamusoro yeFCAS yeQ1 gore rino yaiva zviitiko zvitatu zvisingatarisirwi "kuparadzanisa": apo mitsetse yakawanda yekufambisa kumaodzanyemba kweNSW yakagumburwa semugumisiro wekupisa kwemasango, kuparadzanisa kuchamhembe kubva kumatunhu ekumaodzanyemba kweNEM musi wa4 Ndira;kupatsanura kunodhura zvakanyanya, apo South Australia neVictoria dzakagara pachitsuwa kwemazuva 18 zvichitevera dutu rakamisa tambo dzekufambisa musi wa31 Ndira;uye kupatsanurwa kweSouth Australia nekumadokero kweVictoria's Mortlake Power Station kubva kuNEM musi wa 2 Kurume.
Kana iyo NEM ichishanda seyakabatana sisitimu FCAS inogona kutorwa kubva mukati megedhi yese, ichibvumira AEMO kufona kune zvakachipa zvinopihwa kubva kune vanopa senge majenareta, mabhatiri uye zvinotakura.Munguva yezviitiko zvekuparadzana, FCAS inofanirwa kutorwa munharaunda, uye mune yekuparadzaniswa kwemazuva gumi nemasere kweSA neVictoria, yakazadzikiswa nekuwedzera kupihwa kubva kuchizvarwa chinopfutirwa gasi.
Nekuda kweizvozvo, NEM system inodhura muQ1 yaive $310 miriyoni, iyo rekodhi $277 miriyoni yakashongedzwa kusvika kuFCAS inodiwa kuchengetedza kuchengetedzwa kwegridi mumamiriro ezvinhu aya anoshamisa.
Kudzokera kune yakajairwa sisitimu inodhura madhora mazana matanhatu emamiriyoni emadhora muQ2, iyo FCAS yakaita madhora makumi mana nemashanu emamiriyoni, "zvainyanya kukonzerwa nekushaikwa kwezviitiko zvekupatsanura masimba makuru", akadaro AEMO muQ2020 yayo.Quarterly Energy Dynamicsreport.
Hukuru-mwero solar inobatsira kudzikiswa kwemitengo yemagetsi
Panguva imwecheteyo, Q2 2020 yakaona avhareji yedunhu rekutengesa magetsi nzvimbo mitengo ichisvika pamazinga avo akaderera kubvira 2015;uye 48-68% yakaderera pane zvavaive muQ2 2019. AEMO yakaronga zvinhu zvakakonzera kuderedzwa kwemutengo wekutengesa sezvizvi: "yakaderera gasi nemitengo yemarasha, kurerutswa kwezvipingamupinyi zvemarasha paMount Piper, kuwedzera kwemvura (uye kubuda kwehydro), uye zvitsva. renewable supply”.
Grid-scale variable renewable energy kubuda (mhepo uye solar) yakawedzera ne454 MW muQ2 2020, ichiverengera 13% yemusanganiswa wekupa, kubva pa10% muQ2 2019.
Yakaderera-inodhura renewable simba rinongowedzera mupiro waro mukudzikisa mutengo wesimba rekutengesa;uye dandemutande rakaparadzirwa uye rakasimbiswa rekufambisa kwakabatana, pamwe chete nemitemo yakadzokororwa inotonga kubatanidza bhatiri muNEM, inobata kiyi yekuve nechokwadi chekuwana kukwikwidza kwemitengo yeFCAS sezvinodiwa.
Zvichakadaro, Cerini anoti vanogadzira uye vanoisa mari vari kutarisisa chero njodzi yakawedzera kumitengo yeprojekiti: "Sezvo mitengo yezvitoro zvadzikira, nguva dzekutenga magetsi dzakapfupika, uye kurasikirwa kwezvinhu zvachinja," anotsanangura kudaro.
Cornwall Insight yakaratidza chinangwa chayo chekupa FCAS mutengo wekufanotaura kutanga munaGunyana 2020, kunyangwe mhando dzezviitiko zvakakonzera kuti FCAS iwedzere muQ1 yakaoma kufunga.
Zvakangodaro, Cerini anoti, "zvikwereti zveFCAS zvave padanho rekushingairira."
