Ol Peaker Plant Em Wanem?

Ol 'peaker plants' em ol pawa jeneresen fasiliti we i save wok tasol long taim we i gat bikpela askim long pawa, ol i kolim 'peak demand'. Ol dispela plent i save wok inap long 2,000 aua long wanpela yia-sampela taim inap long 250 aua-na dispela i mekim ol i narakain tru long ol pawa plent we i save wok oltaim.

Ol wok bilong wanpela 'peaker plant' i stap long 'rapid response capabiliti'. Planti ol 'peakers' bilong nau i save yusim ol simpol -saiklon ges tabin we i save kukim ges, na wok wankain olsem ol jet ensin. Taim ol grid opereta i luksave olsem diman i go antap, ol dispela tabin i ken stat long kamapim pawa insait long 5 i go inap 15 minit.

Dispela wok i save wok long tripela step: wanpela kompresa i save pulim win i go insait long ensin na putim presa long en, ol fiul injekta i save miksim netsurel ges wantaim dispela presa win insait long ol rum bilong paia we tempereja i winim 2,000 digri F, na dispela hai-presa ges strim i save tanim ol 'turbine blades' we i save kirapim ol jenereta long kamapim pawa. Dispela simpol-saiklon disain i sakrifaisim gutpela wok bilong spit-thermodynamic efisiens i stap namel long 20% i go inap 42%, taim yumi skelim wantaim ol kombinesen-saiklon plent we inap long kamap 60% gutpela wok tasol i save kisim planti aua long kamapim ful autput.

Ol opereta bilong grid i save salim ol 'peakers' long gutpela rot. Long ol de, ol 'baseload' plent olsem nuklia, ston kol, o ol 'combined-cycle gas' fasiliti i save givim pawa oltaim. Tasol taim ol ea kondisen i save givim hevi long grid long taim bilong san, taim ol lektrik hita i ran ovataim long taim bilong kol, o taim diman i go antap long apinun taim ol manmeri i go bek long haus na opim ol masin, ol 'peakers' i pasim spes namel long saplai i stap na diman i go antap.

Yunaitet Stets i gat samting olsem 999 'peaker' plent long 2021, bihainim ol data bilong gavman. Ol dispela fasiliti i save kamapim 3.1% bilong pawa jeneresen long wanwan yia tasol ol i makim 19% bilong olgeta disain kapasiti-na dispela i soim klia olsem ol i save kamap wanwan taim. Planti i save kukim 'natural gas', tasol olpela haus i save yusim disel, fiul oil, o ol wara we i gat petrolium long en olsem bek-ap fiul.

Global peak pawa maket i bin kamap long $124.66 bilien long 2024 na ol i ting bai gro i go long $177.32 bilien long 2032, we i soim wanpela kompaun anuel grot reit bilong 4.32%. Dispela gro i no stret wantaim tingting bilong ol manmeri olsem 'renewable energy' bai daunim nid bilong ol 'peakers'. Tasol, yusim bilong ol i go antap long las faivpela yia.

Sapos yu kliagut long wanem taim ol 'peakers' i wok, dispela bai soim as na ol i stap yet olsem bikpela samting maski ol i no gat planti wok. Ol bikpela aua i save senis bihainim klaimet na sisen. Long ol ples we ples i no hat tumas, ol aua bilong apinun i save lukim bikpela askim bikos ol hauslain i save yusim ol lait, ol samting bilong haus, na ol samting bilong amamas wantaim. Ol hotpela klaimet i save kamap bikpela tru long apinun taim ol 'air conditioning' i bung wantaim ol wok bisnis we i wok yet. Ol kolpela klaimet i save kamap long moningtaim taim ol wok bilong hatim spes na ol wok bilong indastri i stat wantaim.

Ol dispela paten i no ol samting we yumi ken save long en long olgeta de. Ol bikpela weta i save kamapim ol bikpela askim. Winta storm long Texas long 2021 i soim dispela hevi taim ol konvensenel pawa sos i no wok gut na diman i winim mak we i stap, na dispela i mekim na planti pawa i pawa. Ol grid opereta i save redim ol 'peakers' stret long ol dispela bikpela taim we i save kamap sampela taim tasol long wanpela yia tasol i save kamapim hevi long grid stebiliti.

Ekonomik model i soim dispela samting. Bikos ol 'peaker' i no save wok planti taim, pawa ol i save kamapim i gat bikpela prais-planti taim $150 i go inap $198 long wan wan megawatt-aua bilong ol 'open-cycle gas turbines, taim yumi skelim wantaim liklik pe bilong 'baseload power'. Ol Peaker opereta i save kisim mani long rot bilong salim eneji long taim bilong operesen na pe bilong kapasiti bilong redi, na dispela i mekim bisnis i kamap gutpela maski ol i no yusim planti.

Envairomen profail bilong ol 'peaker' diwai i gat bikpela salens. Taim ol i wok, ol 'peakers' i save rausim bikpela polusen long wan wan yunit bilong pawa winim ol narapela fosil fiul plent. EPA data i soim olsem taim ol 'peakers' total annual sulfur dioxide emitions i bin 96.8% daunbilo long ol non-peakers (bikos ol i no save wok planti taim), median peakers i bin rausim 1.6 taims moa salfa daioksait long wan wan yunit bilong pawa ol i kamapim.

Dispela bikpela 'emission rate' i kamap bikos planti 'peakers' i no gat gutpela 'emission control' teknoloji. Ol ikwipmen we ol i nidim long rausim ol doti i save givim bikpela pe na hevi we i no inap long helpim ol plent we i wok inap sampela handet aua tasol long wanpela yia. Olsem na, ol 'peakers' i save rausim ol kain kain mak bilong 'nitrogen oxides', 'sulfur dioxide', na ol liklik hap 'pollutants' we i save kamapim hevi long 'respiratory', 'cardiovascular issues', na bagarap long 'nervous system'.

Ol paten bilong ples i save mekim hevi bilong helt ikwiti i kamap bikpela moa. Statistikel analisis bilong Gavman Akauntebiliti Opis i painim olsem ol komyuniti we i no gat planti samting long bipo i save stap klostu long ol 'peaker plants'. Wanpela komyuniti we i gat 71% hevi long bipo ol i ting em bai stap 9% klostu long 'nearest peaker' winim wanpela komyuniti we i gat 40% hevi long bipo. Moa long wan milien pipel i stap insait long tripela mail long sampela bikpela ples, we i stap long ol taun we i gat planti manmeri i stap we polusen i save bagarapim ol lain we i no gat strong na i gat bikpela hevi long envairomen.

Ol bateri pek litiami wok long kamap olsem namba wan rot bilong senisim ol 'fossil fuel peakers', na dispela i senisim tru 'economics' bilong 'peak power'. Ol bateri eneji stoa sistem i ken mekim wankain grid-balansing wok olsem ol ges tabin na tu i gat sampela gutpela samting: taim bilong bekim ol samting ol i skelim long milisekon na i no long minit, zero on-sait emisen, na nogat fiul kos long taim bilong wok.

Kost kompetitivnes i kamap long wanpela 'tipping point'. Klin Eneji Kaunsil bilong Ostrelia i painimaut long 2021 olsem ol bateri i ken i stap 30% moa long ol nupela ges peaker plent. Analisis we i skelim ol kos we i wankain i soim olsem wanpela foapela-aua bateri sistem i stap klostu long $156 long wan wan kilowatt-yia na $234 bilong wanpela open-saiklon ges tabin. BloombergNEF risets i soim olsem ol lithium-ion bateri nau i no gat bikpela pe tumas winim ol ges peaking plent long planti hap bilong wol, wantaim wanpela global mak bilong $132/MWh long foapela-aua yutiliti-skel bateri skelim wantaim $173/MWh bilong ol ges peaking.

Ol 'real-world deployment i soim dispela senis. New York Power Authority i wok long senisim ol 'gas peakers' wantaim ol 'battery storage'. Long Ventura County, California, 142 Tesla Megapacks we i givim 100 MW i senisim wanpela ges peaker plent. Belgium i salim 40 Tesla Megapacks (50 MW) long senisim wanpela 'turbojet' jenereta. Pacific Gas & Electric i kisim tok orait long 300 MW bilong eneji stoa long senisim tripela netsurel ges peka plent-em i nambawan eksampel inap nau long ol bateri we i senisim fosil fiul jeneresen long Amerika.

Dispela teknoloji i wok gut tru long stretim hevi bilong "duck curve" long ol sola-hevi grid. Ol bateri i save sasim taim sola jeneresen i winim diman long biknait, na bihain ol i save lus long apinun taim sola autput i go daun tasol diman i go antap. Dispela paten i stret wantaim ol 'peaker operation' sediul bilong tripela o foapela aua long olgeta apinun.

Ol sistem bilong putim ol bateri i save bungim ol hevi bilong taim we ol 'gas peakers' i no save bungim. Wanpela 'gas turbine' wantaim 'fuel supply' inap long ran oltaim, tasol ol bateri i save pinis bihain long 'discharge period' bilong ol-planti taim tupela o foapela aua long ol 'utility-skel instolesen. Dispela tambu em i bikpela samting long taim bilong ol 'extended peak events' o ol 'multi-'de weta imejensi.

Tasol, ol lo bilong maket i wok long senis na i laikim longpela taim bilong putim ol samting. ISO New England i tingting long senisim wanpela kwalifaing kapasiti fremwok (we i nidim tupela-aua longpela taim) i go long wanpela gutpela lod-karim kapasiti fremwok we i gutpela long veliuim ol risos we i gat longpela taim-.

Ol bateri i ken kisim mani long rot bilong planti grid sevis: 'frequency regulation' (em i nambawan rot bilong kisim mani), 'energy arbitrage' (baim pawa taim em i no gat bikpela pe, salim taim em i dia tumas), na 'capacity payments'. Risets i soim olsem 'frequency regulation' i save givim bikpela hap bilong ekonomik riten, tasol dispela gutpela samting i ken go daun taim moa stoa i go insait long maket na kompetisen bilong ol dispela sevis i go antap.

Bateri bagarap i makim wanpela bikpela wari long wok. Ol 'lithium-ion cells i save pinis long taim bilong 'charge-discharge cycles, na i mas mekim bikpela tumas taim ol i putim long en long holim wok bilong en insait long 10-15 yia laipspan.

Dispela liklik 'cycling rate' i stret long 'lithium-ion' teknoloji, long wanem, ol bateri i save mekim 5,000+ 'cycles' pastaim long ol i bagarap nogut tru.

Tingting bilong 'peaker' bilong bipo i wok long senis. Long bipo, ol dispela plent i save go antap long 100% lod hariap tru, ran long taim bilong bikpela wok, na bihain ol i pasim. Bikpela senis long 'renewable energy' i kamapim wanpela nupela kategori: 'load-bihainim pawa plent.

Load-ol plent i wok long ol kain kain hap lod long longpela aua, na ol i save stretim autput bilong en long skelim ol 'renewable intermittency'. Ol i no bekim ol 'dely demand peaks' we ol i ken save long en, ol i save kompensetim ol 'minit-to-minit senis long win na sola jeneresen. Dispela wok i nidim hariap bekim, bikpela fleksibiliti, na planti taim zero-minit stat kapasiti. Sampela fasiliti nau i save bungim ol 'gas turbine' wantaim ol 'battery storage-bateri i save givim kwik bekim taim ol 'turbine' i wok long stat, na bihain 'turbine' i save kisim ples bilong ol longpela taim.

Planti rot i wok long kamap long kamapim gutpela 'peaking capacity'. Ol ges tabin we i gat haidrojen- i makim wanpela rot. Mitsubishi Power i kamapim ol hevi-diuti tabin we inap long 30% haidrojen ko-firing tude, wantaim ful haidrojen konvesen inap long bihain taim. Ol dispela 'turbines' inap long daunim CO2 emisen long 65% taim yumi skelim wantaim ol 'traditional coal plants' na tu holim strong 'rapid response capability' we i bikpela samting long mekim wok i go antap. Tupela projek bilong Not Amerika we i yusim ol dispela 'turbines' long ol bikpela wok bilong en bai kamap long wok bisnis insait long tupela o foapela yia bihain.

Ol 'hybrid' sistem we i bungim ol 'renewable' wantaim 'storage' i givim narapela rot bilong stretim hevi. Arizona Pablik Sevis i bin kisim kontrak long 65 MW bilong sola pawa wantaim 50 MW, 135 MWh lithium-ion bateri benk we i save givim pawa long taim bilong bikpela diman long 3:00 i go inap 8:00 PM. Florida i plen long wokim 409-megawatt Manatee sistem we wanpela sola plent i stap klostu bai sasim, na dispela bai senisim tupela olpela ges yunit.

Ol 'virtual power plant' (VPP) i save bungim ol eneji risos long rup-sola antap long rup, bateri stoa, smat temostat, lektrik vehikel saja-na operetim ol wantaim. Risets bilong Brattle Grup i soim olsem ol VPP inap long givim wankain kapasiti olsem ol 'peaker plant' long liklik pe na ol 'emissions'. Ol 'demand response' program, we ol yusa i save daunim konsumsen long taim bilong 'peak period' na kisim kompensesen, i save givim narapela rot long 'supply-side peaking capacity.

Bateri stoa i winim kompetisen bilong kisim nupela peaking kapasiti long ol stet we i gat strongpela klinpela eneji polisi. 2050 'carbon-neutral grid mandate' bilong California i bin rausim ol nupela 'gas peaker' plent long kisim tok orait bilong ol reguletori.

Dispela senis i bungim ol narapela narapela spit long olgeta rijen. Ol kantri we i gat planti liklik ges na ol polisi bilong klaimet we i no strong tumas i wok long laikim ol 'gas peakers'. Ol plen bilong Florida long bungim ol risos i gat nupela ges-paia pawa olsem wanpela grid-balansing tul. Tasol, maski i no gat presa bilong polisi, prais bilong 'lithium-ion' i wok long pundaun na dispela i mekim ol bateri i kamap gutpela long planti maket.
