Ekifo kya Gateway Energy Storage e San Diego kyayaka okumala ennaku musanvu ez’omuddiring’anwa mu May 2024. Battery emitwalo kkumi na ttaano. Ennaku musanvu ez’abazinya mwoto nga bayimiridde awo, nga tebasobola kukola kinene okuggyako okulinda n’okulaba ennimi z’omuliro nga zizina okuyita mu lithium 15 MWh. Abasooka okuddamu bwe baatuuka, tebaamanya oba baali bakolagana ne "enkola y'okutereka amaanyi ga bbaatule," "enkola y'okutereka amaanyi," oba "okuteeka bbaatule okutambula"-era okutabulwa okwo kwabafiiriza eddakiika ez'omuwendo okuzuula enkola ki ezikozesebwa.
Ebitongole bisatu eby’enjawulo byalaze nga biriko enteekateeka ssatu ez’enjawulo ez’okuddamu. Omu yagoberera ebiragiro bya NFPA 855 ku "enkola z'okutereka amaanyi ezitakyukakyuka." Ekirala kyajuliza amateeka g'ekitundu nga gagiyita "Enkola y'okutereka amaanyi ga bbaatule eya Tier 2" okusinziira ku busobozi bwayo 600+ kWh. Ebiwandiiko by'ekifo kino byennyini byakiwandiika nga "BESS" nga tebinnyonnyodde ekyo kye kyalimu okusukka bbaatule zennyini.
Kino tekyali kya makulu gokka. Yali kizibu kya bukuumi ekyamala essaawa 168 ekyabikkula okumenya okwali kudduka mu mulimu gwonna: tetusobola kukkiriziganya wadde ku bye twogerako.
Obuzibu si nti enkola z'okutereka amaanyi ga bbaatule mpya-lithium-ion grid storage ebadde eteekebwa mu nkola okumala emyaka egisukka mu kkumi. Kwe kuba nti ennyonyola zeeyongedde mangu okusinga tekinologiya yennyini. Buuza "enkola y'okutereka amaanyi ga bbaatule kye ki" eri abakwatibwako kkumi ab'enjawulo era ojja kufuna eby'okuddamu kkumi eby'enjawulo, nga buli kimu kissa essira ku bitundu eby'enjawulo, emitendera, oba emirimu. IEEE ekinnyonnyola mu ngeri emu. NFPA 855 endala. Enfuga z’ebitundu zikola ebika byazo. Abakola ebyuma bakozesa ebigambo eby’enjawulo. Mu mwaka gwa 2025, omukugu mu kukola pulojekiti mu Texas ayinza okuba ng’akozesa olulimi olw’enjawulo ddala okusinga omuduumizi w’abazinya mwoto mu California okunnyonnyola tekinologiya y’emu ddala.
Kino kikulu kubanga ennyonyola zisalawo buli kimu-okuva emitendera gy’obukuumi gye gikwata ku ngeri pulojekiti gye zikkirizibwamu, yinsuwa, n’okukkakkana, ssente mmeka ze zigula. Johnson County, Iowa bw’egabanya enkola mu ngeri ey’enjawulo okusinga New York State, abazikola boolekagana n’ekizibu ky’okulungamya ekiyinza okwongera emyezi ku biseera n’obukadde ku mbalirira. Ebitongole by’omutindo bwe bitasobola kukwatagana oba okussa essira ku bitundu bya bbaatule, okugatta enkola mu bujjuvu, oba okukozesa omukutu, omukutu gwonna ogw’okugaba ebintu gukutuka.
Enkyukakyuka eno si ya kimpowooze. Kiraga obutakkaanya obwa nnamaddala ku bisinga obukulu: BESS okusinga etegeezebwa kemiko ya bbaatule yaayo? Omusingi gw’obusobozi bwayo? Ensonga yaayo ey’okukozesa? Obukuumi bwayo? Abakwatibwako ab’enjawulo baddamu mu ngeri ya njawulo, era buli ky’okuddamu kikola obuwumbi n’obuwumbi mu nsimbi eziteekebwa mu bikozesebwa.
Lwaki Ennyonyola z’okutereka bbaatule zakubisibwamu mu kifo ky’okugatta
Tekinologiya ezisinga zisenga ku nnyonyola ez’omutindo nga bwe zikula. Emmotoka. Kompyuta za kompyuta. Ebikozesebwa mu kukola amasannyalaze g’enjuba. Naye enkola z’okutereka amaanyi ga bbaatule zakutuka ne zifuuka enkola ez’enjawulo ezitakka wansi wa 14 ez’enjawulo mu bitundu eby’enjawulo n’ebitongole ebivunaanyizibwa ku mutindo mu mwaka gwa 2024, okusinziira ku Pacific Northwest National Lab okwekenneenya amateeka g’ekitundu.
Okwawukana kuno kugoberera okusika omuguwa okusatu okukulu okuzimbibwa mu tekinologiya yennyini.
Kemiko okusinziira ku nkola.Ennyonyola ezimu zeesigamiziddwa ku bbaatule ky’ekoleddwa mu-lithium-ion, bbaatule ezikulukuta, sodium-sulphur. Abalala essira balitadde ku ky’ekola-okulungamya emirundi, okusenya ku ntikko, okugatta amasannyalaze agazzibwawo. Abakugu mu makolero bwe bakubaganya ebirowoozo ku nkola y’okutereka amaanyi ga bbaatule kye ki, okusika omuguwa kuno kuvaayo mangu: NFPA 855 eggumiza engeri z’obukuumi bw’omuliro eza kemiko ez’enjawulo. Omutindo gwa ISO gussa essira ku busobozi bw’emirimu. Tewali nkola zombi nkyamu, naye zigonjoola ebizibu eby’enjawulo, ekikutulakutula engeri enkola gye zisengekebwamu, okuteekebwawo, n’okulung’amibwa.
Ekipimo kya kWh 600 kyafuuka layini egabanya mu butanwa. Enfuga zaali zeetaaga engeri ennyangu ey’okwawula enkola z’amayumba-okupima okuva ku bikozesebwa-ekipimo, kale bangi baatwala akabonero ka NFPA aka kWh 600 ng’ekifo eky’okuwummulamu olw’ebyetaago by’obukuumi eby’ongera. Naye omuwendo guno gwasibuka mu kugezesa obukuumi bw’omuliro, so si ku njawulo yonna mu nkola mu ngeri tekinologiya gy’akola oba gy’aweerezaamu omukutu. Okusukka kWh 600, enkola zino zoolekedde ebyetaago by’okuziyiza omuliro mu bizimbe, ebiragiro by’okuziyiza omuliro, n’omutindo gw’okutendeka abakozi. Wansi w’omusingi ogwo, amateeka gawummulamu nnyo.
Kino kyaleetawo okukyusakyusa mu katale. Abamu ku bakola enkola za kWh 590 mu ngeri ey’enjawulo okwewala omutendera omukakali, ne bwe kiba nti enkola ennene yandikoze bulungi ebyetaago bya giridi. Abalala bagamba nti kemiko kikulu okusinga obusobozi-nti enkola ya lithium iron phosphate eya MWh emu erina akabi akatono okusinga okuteekebwamu kwa kWh 400 eza nickel manganese cobalt. Ebifo byombi birina omugaso, y’ensonga yennyini lwaki ennyonyola tezikwatagana.
Ebiwandiiko ebitali bikyuka okusinziira ku tekinologiya agenda akulaakulana.Emitendera egisinga ginnyonnyola okutereka bbaatule nga kwesigamiziddwa ku kuteebereza okw’omulembe gwa 2020-ku kufuga kwa lithium-ion, okumala essaawa bbiri-ku -nnya, n’emabega-mita-mita oba utility-okukozesebwa-scale. Naye bbaatule za sodium-ion zayingira mu kuteekebwa mu nkola mu by’obusuubuzi mu 2024. Battery ezikulukuta zituuka ku bbeeyi parity okumala ebbanga eddene. Tekinologiya wa solid-state alina emyaka etaano okuva ku minzaani y’ebikozesebwa. Ebitongole by’omutindo bitereeza ku nsengekera z’emyaka esatu-okutuuka ku etaano. Tekinologiya akulaakulana buli mwaka. Okuddirira okw’ennyonnyola kuleeta okusika omuguwa mu mateeka mu kiseera kyennyini ng’obuyiiya bwanguyira.
Ekitongole ekinoonyereza ku masannyalaze kino kyawandiika mu kwekenneenya kwabwe okwagwa mu 2024: 19% ku pulojekiti za bbaatule ezikola zafuna okukendeera kw’amagoba olw’okulwawo okutandika okukola n’ensonga z’okukola, nga nnyingi zaava ku nsalo ezitali zitegeerekeka mu kiseera ky’okukkiriza. Ekitongole kya New York State Energy Research & Development Authority bwe kyakola etteeka lyabwe ery’ekyokulabirako mu 2020, tebaasobola kuteebereza nti abakola mu 2025 bandiba nga bateeka enkola ez’omugatte nga zigatta kemiko za bbaatule ssatu ez’enjawulo mu kifo kimu okusobola okulongoosa enkola ez’enjawulo ez’okukozesa. Ennyonyola eziriwo kati tezikwata ku nsonga eno entuufu.
Omulimu gwa grid okusinziira ku by’obugagga ebirabika.Wano we kifunira ekizibu mu butuufu. Enkola y’okutereka bbaatule etegeezebwa kiki ky’eri oba ky’ekola? Okuteekebwawo kwa MW 100 / MWh 400 mu California kuyinza okuwa arbitrage y’amasoboza essaawa emu, okulungamya frequency eddako, n’empeereza y’okuyimirizaawo okutambuza essaawa eyokusatu-byona mu lunaku lumu olw’okukola. Nnyonyola ki ekola? Eyo eyassa essira ku mpeereza ya grid? Eyo eyesigamiziddwa ku bikwata ku bintu ebirabika? Oyo esibiddwa ku mutindo gw’okuyungibwa?
Lipoota ya NERC eya 2023 ku kulemererwa okutereka bbaatule yalaga okusika omuguwa kuno nnyo. Ensobi eya bulijjo-erongoosebwa bwe yaleetera obusobozi bwa bbaatule bwa MW 498 okugwa nga tebuvudde ku mutimbagano, bambega baalwana okugabanya oba okulemererwa kwali nsonga ya by’obugagga eby’omulembe, ekizibu ky’eby’obugagga ebyesigamiziddwa ku inverter-, oba enkola y’okutereka amaanyi obutakola bulungi. Obutategeeragana mu nnyonyola bwalwawo okwekenneenya emirandira era ne bukendeeza ku kussa mu nkola enkola z’okuziyiza mu makolero gonna.
Ekivaamu mu nkola: pulojekiti y'okutereka bbaatule mu kitundu kya MISO eyinza okuteekebwa mu kibinja kya "okutereka amaanyi" wansi w'enkola emu, "eky'obugagga ky'amasoboza ekisaasaanyizibwa" wansi w'endala, "eky'obugagga ekyesigamiziddwa ku inverter-" wansi w'ekyokusatu, ne "eky'obugagga ky'omulembe" wansi w'eky'okuna-mu kiseera kye kimu. Buli kugabanya kuleeta ebyetaago eby’ekikugu eby’enjawulo, ebiragiro bya yinsuwa eby’enjawulo, n’ebiragiro eby’enjawulo eby’emirimu.
Omuwendo Omutuufu-ensi yonna ogw'okutabulwa mu nnyonyola
Ebizibu by’ebigambo ebitaliimu bifuuka bya ddala bwe bikuba ebyenfuna bya pulojekiti. Okwekenenya kwa Ontario Grid okwa 2024 kwazuula nti obutategeeragana mu nnyonyola bwayongera wakati w’emyezi 8-12 ku biseera by’okuyungibwa ku pulojekiti za bbaatule, bw’ogeraageranya n’omulembe ogwa bulijjo, olw’enkaayana z’okugabanya mu mateeka.
Lowooza ku bibaawo ku mutendera gw’okugaba olukusa mu kitundu. Enkola ya Rangebank Battery Energy Storage System-Pulojekiti ya Shell Energy eya 200 MW / 400 MWh mu Victoria-bwe yayita mu kukkirizibwa, ab'obuyinza mu bitundu baalina okusalawo oba yalina ebisaanyizo nga "energy infrastructure," "industrial facility," oba "utility installation." Buli mutendera gwaleetawo obukwakkulizo obw’enjawulo mu kugabanya ebitundu, ebyetaago by’okudda emabega, n’enkola z’okwebuuza ku bantu. Pulojekiti eno ku nkomerero yatuuka ku buwanguzi, naye okukubaganya ebirowoozo okufaananako n’okunnyonnyola kusse pulojekiti ezitasobola kutambulira mu butakakasa.
Ebitongole ebizikiriza omuliro bye bisinga okutawaanya ekizibu kino. Ekibiina ky'ensi yonna ekigatta abakulira abazinya mwoto kyafulumya obulagirizi bw'okuddamu mu mbeera ez'amangu mu 2024 nga mu bukulu busuula emikono gyayo waggulu: "Salawo ekifo kye kyeyita, olwo osala-reference n'omutindo ogukozesebwa." Abasooka okuddamu balina okumanya mu sikonda ntono oba bakolagana n’embeera y’okudduka mu bbugumu eyeetaaga okukola emirimu egy’okwekuuma oba omuliro ogw’amasannyalaze ogwa bulijjo nga gulina enkola z’okuziyiza eza bulijjo. Abakozi abatuuka bwe basisinkana enkola eziwandiikiddwa wansi w'enkola ttaano ez'enjawulo ez'okutuuma amannya-"BESS," "ESS," "okutereka bbaatule," "bbaatule za grid-scale," "okutereka amaanyi agatali gakyukakyuka"-nti omugugu gw'okutegeera gukulu. Okubwatuka kwa McMicken mu Arizona kwasomesa essomo eryo mu 2019, kyokka abazinya mwoto bana ne basasula omuwendo.
Abawandiisi ba yinsuwa bassa omuwendo gw’obutategeeragana buno butereevu mu ssente z’omusaala. Okwekenenya kwa Amwins Group okwa 2024 ku yinsuwa y’okutereka bbaatule kwazuula nti okutegeera obulungi ennyonyola kukwatagana mu ngeri ey’ekifuulannenge n’ebisale bya yinsuwa. Pulojekiti ezirina ensengeka entegeerekeka, ezituufu mu nkola zonna ezifuga zifuna okusasulwa ku ssente entono ebitundu 15-20% okusinga pulojekiti ezifaanagana mu nkola ezikwatibwa mu zoni enzirugavu ezitegeeza. Ensonga: abawandiisi b’ebiwandiiko tebasobola kugerageranya bulungi bulabe ku by’obugagga bye batasobola kugabanyaamu buli kiseera.
Enjegere z’okugaba ebintu nazo zikutukakutuka ku layini ezitegeeza. Abakola bbaatule bakola ebintu okutuukana n’omutindo ogw’enjawulo-UL 9540, IEC 62619, UN 38.3 ku ntambula. Naye ebiragiro bya pulojekiti bwe bijuliza "enkola z'okutereka amaanyi ga bbaatule" awatali kulambika nkola ki ey'ennyonnyola ekola, abakola ebintu boolekagana n'okulonda okutasoboka. "BESS" erimu enkola y'okukyusa amaanyi? Enkola y’okuddukanya amaanyi? Ebikozesebwa mu kuddukanya ebbugumu? Ennyonyola ez'enjawulo zigamba ebintu eby'enjawulo, ne ziwaliriza abakola oba okusukka-enkola za yinginiya okutuukiriza buli ntaputa esoboka oba mu kabi okugamba nti tebagoberera mateeka.
Ekizibu ky’okutandika okukola kiraga engeri ennyonyola gye zikubisaamu obuzibu bwa pulojekiti. Okwekenenya kwa NREL okwa 2024 ku nsaasaanya yazuula nti enkola z’okutereka bbaatule mu bujjuvu zeetaaga okusukkiridde ebitundu 15-25% okusobola okubala okuvunda n’okukakasa nti zikakasa omulimu. Naye "omutindo" gufuna okunnyonnyolwa mu ngeri ey'enjawulo okusinziira ku oba olongoosa ku:
Amaanyi agasinga obunene agafuluma (agapimiddwa mu MW) .
Obusobozi bw’amasoboza (obupimiddwa mu MWh) .
Obulung'amu bw'olugendo lw'okudda n'okudda- (%) .
Obulamu bw’enzirukanya (omuwendo gw’enzirukanya ezenkanankana mu bujjuvu) .
Obudde bw'okuddamu (milliseconds) .
Ebbanga ku maanyi agagereddwa (essaawa) .
Buli metric etegeeza enteekateeka y’enkola ey’enjawulo. Buli dizayini ekola maapu ku biti eby’enjawulo eby’ennyonnyola. Era buli mutendera guleeta amakubo ag’enjawulo ag’okulungamya. Ekivaamu: pulojekiti eziyinza okuteekebwa mu nkola mu myezi 18 ziwanvuwa okutuuka ku myezi 30, ate abakola batambulira mu bifo ebitegeeza (definitional labyrinths) ebitaliiko kakwate na nkola ya tekinologiya yennyini.
Engeri Abakwatibwako Enjawulo gye Bannyonnyola Ebikulu
Abazinya mwoto tebafaayo ku megawatt. Abaddukanya grid tebafaayo ku chemistry. Abawandiisi ba yinsuwa byombi babifaako naye nga bizitowa mu ngeri ya njawulo. Okumenya okw’ennyonnyola kulaga ebikulu eby’enjawulo ddala mu nkola yonna ey’okutereka bbaatule.
Ebitongole ebivunaanyizibwa ku mutindo bissa essira ku bipimo by’obukuumi.Ennyonyola ya NFPA 855 yeetoolodde okuziyiza okudduka okw’ebbugumu, ebyetaago by’okugabanyamu ebitundu, n’ebipimo by’okulwanyisa okubwatuka. Omutindo gugabanya enkola okusinziira ku busobozi bw’amasoboza gonna naddala kubanga metric eyo ekwatagana n’obuzibu bw’ebivaamu mu mbeera z’okulemererwa. Ekyuma ekidduka mu bbugumu ekya MWh 10 kifulumya amaanyi mangi mu musingi okusinga ekintu ekidduka ekya MWh 1, awatali kulowooza ku kiki enkola eno ky’ekola ku mudumu. Kino kikola amakulu agatuukiridde okuva mu ndowooza y’obukuumi bw’omuliro-era kireeta okusika omuguwa n’abakwatibwako abalowooza nti engeri z’emirimu zikulu okusinga okubalirira kw’okufulumya amaanyi mu mbeera embi ennyo-.
UL 9540 etwala enkoona ey’enjawulo katono, ng’etegeeza okutereka bbaatule okuyita mu kugezesa obukuumi ku ddaala ly’ebyuma-. Omutindo gufaayo ku buziyiza bw’okusaasaana kw’obutoffaali-okutuuka ku-module-okutuuka ku-ensengekera. Elagira enkola ezenjawulo ez’okugezesa okwekenneenya ebiwujjo ebidduka eby’ebbugumu. Abakola ebintu balina okulaga nti "enkola yaabwe ey'okutereka amaanyi ga bbaatule" esobola okubeeramu okulemererwa ku buli mutendera gw'okugatta. Ennyonyola eno ekwata BESS ng’enkola y’obukuumi ey’ensengeka y’ebifo ennyonyola gy’eva mu mpisa z’omulimu ezigezeseddwa okusinga okuva mu mitendera gy’obusobozi oba emirimu gya giridi.
Abaddukanya giridi bannyonnyola okusinziira ku kusindika.CAISO, ERCOT, MISO, PJM-buli Independent System Operator alina ennyonyola ez'enjawulo katono kubanga buli grid erina ebyetaago eby'enjawulo. Ekibuuzo ky’enkola y’okutereka amaanyi ga bbaatule kye ki kifuna okuddibwamu mu ngeri ey’enjawulo okusinziira ku mbeera ya giridi. Mu ERCOT, nga essira liri short-duration frequency response, okutereka bbaatule kufuna okunnyonnyolwa obusobozi bwayo okukuba oba okunyiga amaanyi mu sikonda nnya okuva ku kufuna signal. Enkola ezitasobola kutuukiriza budde obwo obw'okuddamu tezirina bisaanyizo bya "kutereka amaanyi agakola amangu" awatali kufaayo ku busobozi bwazo oba kemiko.
CAISO essira essa essira ku bbanga n’okukyukakyuka mu kusasula, ekiraga okusoomoozebwa kw’e California mu kukoona kw’enkoko. Ennyonyola zaabwe zaawula wakati w'okutereka "ekiseera ekitono-" (essaawa 2-4), "ekiseera eky'omu makkati-" (essaawa 4-8), ne "ekiseera ekiwanvu" (essaawa 8+), kubanga giridi yeetaaga ebikozesebwa eby'enjawulo ku biseera eby'enjawulo. Enkola ya 100 MW / 200 MWh (obudde bw’essaawa 2) ekola omulimu gwa giridi ogw’enjawulo mu musingi okusinga enkola ya 50 MW / 600 MWh (obudde bw’essaawa 12), wadde nga zombi ziyinza okukozesa kemiko ya bbaatule efaanagana.
Essira lino ery’emirimu likola amakulu mu nteekateeka ya grid naye lireeta okulumwa omutwe eri pulojekiti ezagala okuwa empeereza eziwera. Okuteekebwako kwe kumu okw'omubiri kuyinza okuba n'ebisaanyizo nga "okutereka amaanyi" ku nkola emu, "omuwa empeereza ez'okuyambako" ku ndala, ne "eky'obugagga ky'okutambuza" ku kyokusatu-okusinziira ku ngeri gye kisindikibwamu essaawa-okutuuka ku-essaawa.
Abakola pulojekiti bakulembeza ebyenfuna bya pulojekiti.Bannyonnyola okutereka bbaatule nga bakozesa kyonna ekifuula ensimbi okumpi. Singa abagaba amabanja baagala okulaba "okutereka amaanyi" nga kusengekeddwa ng'eby'obugagga eby'omulembe ebirina enkola z'enyingiza ezikakasibwa, ekyo ennyonyola kye ziggumiza mu biwandiiko by'ebbanja. Singa bamusigansimbi b'omusolo gw'omusolo beetaaga enkola ezigabanyizibwa mu biti nga "energy property" wansi w'ebiragiro bya IRS okusaba okukendeeza ku musolo gw'okusiga ensimbi, ennyonyola zikyuka okusinziira ku ekyo.
ITC y'okutereka amaanyi yeetongodde ebitundu 30% mu tteeka erikendeeza ku bbeeyi y'ebintu yatonda ekiragiro ekipya eky'ennyonnyola: okulinnyisa ekitundu ky'ensimbi za pulojekiti ekituukagana n'ebisaanyizo nga "ekintu ekitereka amaanyi" okusinziira ku "balance of system" oba "interconnection." Buli component classification kikulu bwe kisalawo oba omuwendo ogwo gufuna 30% federal subsidy. Amangu ago, ennyonyola zifuuka ebikozesebwa mu by’ensimbi okusinga okufuuka ebikwata ku by’ekikugu.
Abakugu abakola mu bitundu ebitali bimu be basinga okusoomoozebwa. Kkampuni y’eggwanga ekola pulojekiti 20 mu masaza 10 esisinkana enkola 10 ez’enjawulo ez’ennyonnyola. Amasaza agamu gakozesa ebipimo by’obusobozi bw’amasoboza. Abalala bakozesa obusobozi bw’amasannyalaze. Abamu essira balitadde ku kemiko. Abalala bassa essira ku ngeri y’okukozesaamu. Enkola y’emu eya lithium iron phosphate eya 50 MW / 200 MWh eyinza okuteekebwa mu kibinja kya:
"Ekifo ekinene-ekitereka bbaatule" mu Oregon
"Enkola y'okutereka amaanyi mu mutendera gwa 2" mu Iowa
"Eby'omugaso-ekipimo BESS" mu Texas
"Ekifo ekinene eky'amasannyalaze" mu New York
"Okuteekawo okutereka amaanyi ku mutindo gwa Grid-" mu California
Buli nsengeka ejja n’ebyetaago eby’enjawulo eby’olukusa, obukuumi, n’okukola lipoota. Standardizing across this mess costs real money-omukubi omu omukulu yabalirira nti basaasaanya $500,000 buli mwaka just on regulatory navigation across definitional inconsistencies.
Enfuga z’ebitundu zitegeezebwa okusinziira ku kukosebwa kw’ekitundu.Amasaza ne munisipaali zisinga kufaayo ku kiki ekibaawo singa wabaawo ekikyamu mu luggya lwabwe. Ennyonyola zaabwe zissa essira ku kweraliikirira kw’obukuumi obw’ekifo-: amabanga ag’okudda emabega okuva ku layini z’ebintu, ekkomo ku maloboozi, okukosebwa okulabika, enkola z’okuddamu mu mbeera ez’amangu. Sikaani ya Pacific Northwest National Lab eya 2023 yazuula ebitundu 59 byokka mu ggwanga lyonna nga biriko amateeka amategeerekeka agakwata ku kutereka bbaatule-era obuyinza obwo 59 bwali butonze enkola 43 ez’enjawulo ez’ennyonnyola.
Ebitundu ebimu byewola enkola ya New York State’s Tier 1 / Tier 2 model, ekozesa 600 kWh threshold okuva mu NFPA 855. Ebirala byakola thresholds zaabwe: 200 kWh mu bifo ebimu, 1 MWh mu birala, 50 MWh mu birala. Enjawulo eraga embeera z’abantu ez’enjawulo-ebibuga ebingi byagala okulondoola okukakali ku mitendera gy’obusobozi egya wansi okusinga amagombolola g’omu byalo agalina ettaka eddene.
Naye eno y’ensonga entuufu: enfuga ezisinga zaawandiika ennyonyola zazo nga tezikwatagana na bitundu ebiriraanyewo. Omukubi w’ebizimbe ayagala okuzimba pulojekiti ya MW 100 ku layini y’ebintu wakati w’amasaza abiri ayinza okwolekagana n’ennyonnyola ezitakwatagana ddala ku buli ludda lwa layini eyo. Kino si kya kuteebereza-Arizona yakola ku mbeera eno yennyini mu 2023, nga pulojekiti ekwata ku bitundu bibiri yalina okwawulwamu ebifo bibiri eby’enjawulo-ebitegeezeddwa okusobola okumatiza amateeka g’ekitundu agakontana, wadde nga yali kifo kimu ekigatta okuva mu ndowooza y’emirimu.
Awali Ennyonyola z’okutereka bbaatule mu butuufu nga zikwatagana
Wadde nga waliwo okukutukakutuka, amaanyi g’akatale n’eby’okuyiga ebizibu-bisika okutuuka ku kukwatagana okutono mu bintu ebikulu ebitonotono.
Kemiko egenda efuuka etali ya maanyi nnyo mu nnyonyola.Emitendera egyasooka gyassa essira ku lithium-ion okusinziira ku flow okusinziira ku sodium-sulphur kubanga kemiko ez’enjawulo zaali zitegeeza ebikwata ku bulabe obw’enjawulo. Naye nga bbaatule za lithium iron phosphate bwe zaalaga engeri z’obukuumi ez’ekika ekya waggulu bw’ogeraageranya n’enkola za nickel manganese cobalt, era nga tekinologiya wa sodium-ion bwe yayingira mu mpeereza y’ebyobusuubuzi n’omulimu ogugeraageranyizibwa, amakolero gaakitegeera nti kemiko yokka tetegeeza biva mu bukuumi. Ennyonyola ez’omulembe zeeyongera okussa essira ku mpisa z’omulimu ezigezeseddwa-obuziyiza bw’okusaasaana okudduka okw’ebbugumu, obudde bw’okuddamu, obulamu bw’enzirukanya mu mbeera ezenjawulo-okusinga ekika kya bbaatule kyokka.
Omutindo gwa IEC ogw’okutereka amaanyi ogulongooseddwa, ogusuubirwa okumalirizibwa mu 2026, gulaga enkyukakyuka eno. Ebbago ly'ennyonnyola lijuliza "okutereka amaanyi g'amasannyalaze" ng'omutendera omugazi, olwo ne balambika ebyetaago by'omulimu ebitafaayo ku kemiko entongole. Kino kisobozesa tekinologiya omupya okubeera n’ebisaanyizo by’amakubo agateekebwawo mu mateeka nga tekyetaagisa bitongole bya mutindo kulongoosa buli kiseera enkalala z’ebika bya bbaatule ebikkirizibwa.
Ekipimo kya kWh 600 kikaluba ne kifuuka convention.Wadde nga yasibuka mu ngeri ya kimpowooze, omuwendo guno gufunye okutwalibwa okumala ne kiba nti okugulwanyisa kireeta ebizibu bingi okusinga okugukkiriza. Ebitundu ebisoba mu 75% ku bitundu bya Amerika ebirina amateeka agafuga okutereka bbaatule bikozesa enkyukakyuka ezimu ez’okuwummulamu kw’obusobozi bwa kWh 600 olw’obwetaavu obw’obukuumi obw’amaanyi. N’amawanga agaasooka okulonda emitendera egy’enjawulo gasenguka nga gagenda ku kWh 600 okukwatagana ne NFPA 855 n’ebitundu ebiriraanyewo. Abeetabye mu katale nabo bakyuse-abakola ebintu kati bawa kWh 590 ne kWh 610
models nga standard products, okumanya bino maapu eri ebika eby’enjawulo ebifuga.
Ebbanga kwe kugatta obusobozi nga ekisiki ekitegeeza.Okukimanya nti enkola ya MW 100 / MWh 200 (essaawa 2) ekola ku byetaago by’omukutu eby’enjawulo mu musingi okusinga enkola ya MW 50 / MWh 600 (essaawa 12) kivuga enkola empya ez’ennyonnyola ezikola ku busobozi bw’amasannyalaze n’amasoboza. Ebiwandiiko bya California ebikwata ku nteekateeka y’omukutu gwa 2024 bigabanya mu bulambulukufu okutereka okusinziira ku bbandi z’obudde, era ISO endala nazo zigoberera. Ennyonyola eno ey’ebitundu bibiri-ekwata bulungi omuwendo gwennyini ogwa giridi n’engeri z’emirimu.
Ekiragiro kya FERC 841 ku kwetaba mu kutereka amaanyi mu butale bwa wholesale kyasindiikiriza enkulaakulana eno. Nga yeetaaga ISOs okukola enkola z'okwetabamu ezikwata ku bbanga, ekiragiro kyalagira bulungi nti ennyonyola za "energy storage resource" ziyingizaamu byombi obusobozi bw'amasannyalaze (MW) n'obusobozi bw'amasoboza (MWh) ng'ebipimo eby'enjawulo. Kati, abakola bwe bawaayo okusaba kw'okuyungibwa, balina okulaga ebipimo byombi, era ISOs zizigabanya okusinziira ku ekyo.
Ensonga y’okukozesa kwe kwawukana ku nnyonyola y’eby’obugagga.Okweyongera, emitendera gyawula wakati w’ekyo enkola y’okutereka bbaatule-li(ebikwata ku by’obugagga ebirabika) okusinziira ku kiki kye-kola(empeereza ya grid eweereddwa). Kino kisobozesa okuteekebwako kwe kumu okuba n’ennyonnyola y’eby’obugagga ennywevu ate nga kiwa empeereza eziwera omulundi gumu. Obutangaavu bw’ennyonnyola buyamba ku buli kimu okuva ku kuwandiika yinsuwa okutuuka ku ndagaano z’okuyungagana okutuuka ku kugabanya emisolo.
Omuze guno gulaga mu ngeri endagaano z’okuyunga abantu gye zitegekeddwamu. Endagaano za PPA ez'omulembe kati zitera okwawula ebitundu bya "Ennyonyola y'Eby'obugagga" (nga biraga obusobozi, kemiko, engeri z'okuddamu, n'okukakasa obukuumi) okuva mu bitundu "Ennyonyola y'Empeereza" (ebiraga ebikwata ku kusalawo kw'amasoboza, okugaba obusobozi, empeereza ez'okuyambako, n'emikutu emirala egy'enyingiza). Enkola y’emu ey’omubiri esobola okukyuka wakati w’embeera z’okukozesa awatali kuleeta kuddamu kugabanya mu ngeri ya nnyonyola, ekirongoosa okukyukakyuka kw’emirimu.
Ennyonyola Framework Battery Storage Mubutuufu Yetaaga
Amakolero tegajja kukwatagana ku nnyonyola emu ey’ensi yonna-teknologiya aweereza emirimu mingi egy’enjawulo mu mbeera nnyingi ez’enjawulo. Naye tusobola okuteekawo enkola y’ennyonnyola ey’emitendera mingi-ematiza ebyetaago by’abakwatibwako eby’enjawulo awatali kumenya katale. Okutegeera enkola y’okutereka amaanyi ga bbaatule kye ki kyetaagisa okukkiriza endowooza zino eziwera ezikkirizibwa ate nga tukola ensonga ezikwatagana ku mpuliziganya.
Layer 1: Ebikwata ku by’obugagga ebirabika.Buli nkola y’okutereka bbaatule erina okunnyonnyolwa n’ensengeka y’ebipimo eby’ekikugu ebituufu ebitegeeza ky’eri, nga tebyesigamye ku kiki ky’ekola:
Obusobozi bw’amasoboza bwonna awamu (MWh oba kWh) .
Amaanyi agasinga obunene agatasalako (MW oba kW) .
Obudde bw’okufulumya ku maanyi agagereddwa (essaawa) .
Ekika kya kemiko wa bbaatule (lithium-ion [lambika sub-ekika], okutambula, sodium-ion, n'ebirala)
Satifikeeti z’obukuumi (UL 9540, UL 9540A, IEC 62619, n’ebirala)
Ensengeka ey’omubiri (erimu konteyina, ekizimbe-ekissibwa, wansi w’ettaka, n’ebirala)
Ebipimo bino birina okukozesa yuniti ezikwatagana n’omutindo gw’okupima mu bitundu byonna. Omukugu bw'annyonnyola "enkola y'okutereka bbaatule ya lithium iron phosphate eya MW 50 / MWh ng'erina satifikeeti ya UL 9540," omuntu yenna mu mulimu guno-omuduumizi w'omuliro, omuddukanya emikutu, omuwandiisi wa yinsuwa, oba omugabi w'ebyuma-amanyi bulungi ekyo kye kitegeeza mu mubiri.
Omutendera 2: Ebipimo by’okugabanya mu mateeka.Ebifuga bisobola okukozesa enkola zaabyo ez’emitendera waggulu w’ennyonnyola y’omubiri ey’omusingi:
Omutendera gw’obukuumi (okusinziira ku mitendera gy’obusobozi bw’amasoboza:<600 kWh, 600 kWh to 20 MWh, >MWh 20) .
Ekika ky'okuyungibwa (okusaasaanya-okuyungibwa<20 MW, transmission-connected >MW 20) .
Okugabanya ebifo (emabega-mita-, mu maaso-ya-mita, eyeetongodde)
Naye bino ebibikka ku mateeka birina okujuliza ebiragiro bye bimu ebikulu ebirabika okuva mu Layer 1. Kino kisobozesa obuyinza okukuuma okufuga okutuufu okw’ekitundu ku byetaago by’olukusa n’obukuumi nga bwe bakakasa nti abakola pulojekiti basobola okuwuliziganya ebiragiro mu lulimi olw’awamu okuyita mu layini z’amasaza.
Omutendera 3: Ennyonyola z’empeereza y’emirimu.Engeri enkola gye yeetabamu mu butale efuna okunnyonnyolwa okwawukana ku by’obugagga ebirabika:
Enkola z’enyingiza ezisookerwako (okusalawo kw’amasoboza, obusobozi, okulungamya emirundi n’ebirala) .
Ebifaananyi by’emirimu (obudde bw’okuddamu, omuwendo gwa ramp, obudde obutono obw’okudduka) .
Okukyukakyuka mu kusindika (ISO-okufugibwa, okwetegekera, okugatta)
Ebikozesebwa mu kwetabamu (akatale ka wholesale, endagaano z’amawanga gombi, emabega-the-mita optimization)
Layering eno esobozesa okuteekebwako okw’omubiri kwe kumu okuwa empeereza eziwera omulundi gumu awatali kutabulwa kwa nnyonyola. Enkola ya 100 MW / 400 MWh ekuuma ennyonyola yaayo ey’omubiri nga yeetaba mu butale bw’okulungamya emirundi (Layer 3) ng’eky’obugagga ekiyungiddwa ku kutambuza- (Layer 2) nga kigoberera ebyetaago by’obukuumi eby’omutendera ogw’okubiri (era Layer 2).
Amateeka g'okukwatagana kwa cross-layer.Enkola ekola singa layers zikwatagana mu ngeri entegeerekeka. Emisingi emikulu:
Layer 1 specs zirina okuba nga zipimibwa era nga zikakasibwa okuyita mu standardized testing protocols
Ensengeka za Layer 2 zirina okujuliza parameters za Layer 1 nga zikozesa thresholds ezikwatagana
Ennyonyola z’emirimu gya Layer 3 zirina okuba nga zituukirizibwa mu by’ekikugu nga ziweereddwa engeri za Layer 1
Enkyukakyuka ku layeri yonna tezirina kwetaagisa kuddamu kunnyonnyola layeri ndala okuggyako nga obusobozi obw’omubiri bukyuse ddala
Enkola eno efaananako engeri amakolero g’amasimu gye gakwatamu okugabanya spektrum-olina bbandi za frequency ya leediyo ezirabika (Layer 1), ensengeka z’amateeka olw’enkozesa ez’enjawulo (Layer 2), n’okussa mu nkola empeereza ezenjawulo (Layer 3), byonna bikwatagana mu ngeri ekwatagana naye nga bitegeezebwa mu ngeri ey’enjawulo.
Lwaki Okufuna Ennyonyola Entuufu Kikulu Mu Emyaka Ekkumi Egijja
Obusobozi bw’okutereka bbaatule mu nsi yonna busuubirwa okutuuka ku 500 GW / 1,400 GWh mu mwaka gwa 2030, okuva ku nga 50 GW / 130 GWh ezaateekebwa mu nkola ku nkomerero ya 2024. Okukula okwo okw’emirundi 10 kubaawo mu myaka mukaaga gyokka. Singa okugabanyaamu ennyonyola kugenda mu maaso ku miwendo egy’akaseera kano, okusika omuguwa kw’amateeka kwokka kuyinza okukendeeza ku kuteekebwa mu nkola emyezi 12-18 buli pulojekiti-okufuula tekinologiya akyusa ekirooto eky’ekirooto eky’ebitongole.
Emigabo gisukka ebiseera bya pulojekiti. Okutereka bbaatule kye kikulu mu kuggyamu kaboni mu giridi. Buli megawatt ezizzibwa obuggya ekendeezebwa kubanga okutereka tekusobola kuteekebwa mu nkola mangu kimala ekiikirira ekyuma ekikola amafuta g’ebintu ebikadde ekisigala nga kikola. California yakendeeza ku MWh obukadde 2.6 ez’amasannyalaze agazzibwawo mu 2023 olw’obutatereka bumala-ekyo kimala okukola amasannyalaze mu maka 350,000 okumala omwaka mulamba. Ebimu ku kukendeeza okwo biraga obuzibu bw’okutambuza, naye okulwawo kw’ebiragiro ebitegeeza kulemesa pulojekiti z’okutereka okujja ku mutimbagano amangu ekimala okusobola okunyiga amaanyi amayonjo agasukkiridde.
Okulongoosa mu by’okwerinda nakyo kisinziira ku kutegeera obulungi ennyonyola. EPRI bwe yeetegereza ebibaawo mu kulemererwa okuzuula emirandira n’okukola enkola z’okukendeeza, ennyonyola ezitakwatagana mu pulojekiti zonna zifuula okutegeera enkola kumpi obutasoboka. Okulemererwa kwava ku kemiko wa bbaatule, omutindo gw’okugatta enkola, enkola y’emirimu, oba ensonga z’obutonde? Tosobola kuddamu kibuuzo ekyo singa 19% ku pulojekiti zikozesa enkola ez’enjawulo ez’ennyonnyola ezissa essira ku bipimo eby’enjawulo. Ennyonyola entegeerekeka, ezikwatagana zisobozesa okukung’aanya ebikwata ku bantu obulungi, ekisobozesa okwekenneenya obulungi obukuumi, ekitaasa obulamu.
Okuvuganya okugenda mu maaso wakati w’abakola bbaatule mu Amerika ne China kwongera obwangu. China ekola ebitundu 70% ku busobozi bw’okutereka bbaatule mu nsi yonna era efunye omutindo ku nnyonyola ezissa essira ku kulongoosa mu makolero n’okuziteeka mu nkola amangu. Singa abakola eby’okukola mu Amerika bamala emyezi emirala 12-18 nga batambulira mu buzibu bw’okulungamya obw’ennyonnyola bw’ogeraageranya n’abavuganya mu China abayingira mu butale bw’amawanga ag’okusatu, ekyo kilwawo kweyongera mu mbeera y’okuvuganya ey’olubeerera. Amawanga amalala okwettanira emitendera egy’ennyonnyola y’Abachina kubanga gisobozesa okutuukiriza pulojekiti mu bwangu kyandiyongedde okukutulakutula enkola y’okugaba ebintu mu nsi yonna.
Ensaasaanya y’ensimbi scale n’ennyonyola entegeerekeka. Ebisale bya yinsuwa, ebiragiro by’amabanja, n’okuzzaayo emigabo byonna emiwendo mu butakakasa mu mateeka. Okwekenenya okwakolebwa mu 2024 okwakolebwa Gresham House, omuddukanya eby’obugagga by’okutereka bbaatule mu Bungereza, kwazuula nti okutegeera okutegeerekeka mu ndagaano n’okukakasa kukwatagana n’obubonero 60-80 obusingako ku bigambo by’ensimbi. Mu buwumbi bwa ddoola 150 mu nsimbi eziteekeddwa mu kutereka bbaatule ezisuubirwa okutuuka mu 2030, enjawulo eyo ewera obukadde bwa ddoola 900 okutuuka ku kawumbi ka ddoola kamu n’obukadde 200 mu nsaasaanya ya kapito ey’okwongerako-ssente eziyinza okusasula GW ez’enjawulo 3-5 ez’okuteekebwa mu nkola singa enkola z’okulungamya zikwatagana.
Tekinologiya agenda mu maaso mangu okusinga ennyonyola bwe zisobola okutambula. Battery za sodium-ion zatuuka ku kuteekebwa mu nkola mu by’obusuubuzi mu 2024. Battery za solid-state ziweza emyaka 3-5 okuva ku minzaani y’ebikozesebwa. Battery z’empewo ez’ekyuma-ziyinza okukuba obutale mu mwaka gwa 2028. Enkola za hybrid ezigatta kemiko eziwera mu kifo kimu zaatandika dda okukola. Singa ebitongole ebivunaanyizibwa ku mutindo birinda buli tekinologiya omupya okuteekawo ebyafaayo by’emyaka mingi nga tebinnaba kulongoosa nnyonyola, okuddirira kw’okulungamya kujja kugoberera obuyiiya enkalakkalira emyaka 5-10. Ekyo tekiyinza kunywerera.
Ekyetaagisa si nnyonyola emu eya bonna, wabula enkola ekwatagana n’enjawulo entuufu ate nga eteekawo ensonga ezikwatagana. Abazinya mwoto balina okusigala nga bassa essira ku bipimo by’obukuumi. Abaddukanya emikutu gya yintaneeti balina okusigala nga essira balitadde ku busobozi bw’emirimu. Naye buli muntu alina okujuliza ensengeka z’ebintu ze zimu ezisibukamu ng’annyonnyola ensengekera ki ddala. Ekyo kisoboka. Ekyo kituukirizibwa. Era ekyo kyetaagisa nnyo enkyukakyuka y’amasoboza okugenda mu maaso ku sipiidi okutebenkera kw’embeera y’obudde kwe kwetaagisa.
Ebibuuzo Ebitera Okubuuzibwa
Lwaki ennyonyola z’enkola y’okutereka amaanyi ga bbaatule zaawukana nnyo mu bitundu?
Ennyonyola zaawukana kubanga abakwatibwako ab’enjawulo bakulembeza ensonga ez’enjawulo eza tekinologiya. Abakungu mu by’okwerinda mu muliro essira balitadde ku miwendo gy’obusobozi bw’amasannyalaze n’obulabe bw’okudduka okuva mu bbugumu. Abaddukanya emikutu gya yintaneeti essira balitadde ku masannyalaze agafuluma n’ebiseera by’okuddamu. Ebitundu ebifuga bifaayo ku site-specific impacts nga setbacks n'amaloboozi. Okuva okutereka bbaatule bwe kuweereza emirimu mingi mu bitundu ebifuga ebingi, buli kitundu kyakola ennyonyola ezirongooseddwa olw’ebibaluma ebitongole awatali kukwasaganya okuyita ku nsalo. Omusingi gwa kWh 600 gwava mu kugezesa obukuumi bw’omuliro mu NFPA 855 naye ne gufuuka omutindo ogwa de facto obuyinza obulala gwe bwakwata-wadde nga si gwonna. Ekitongole kya Pacific Northwest National Lab kyazuula obuyinza bwa Amerika 59 nga bulina amateeka agafuga okutereka bbaatule nga bakozesa enkola 43 ez’enjawulo ezitegeeza okutuuka mu 2023.
Enkyukakyuka mu nnyonyola ekosa etya ssente za pulojekiti n’ebiseera?
Obutategeeragana mu nnyonyola bwongera emyezi 8-12 ku biseera bya pulojekiti ebya bulijjo okusinziira ku kwekenneenya kwa Ontario Grid okwa 2024, okusinga okuyita mu nkola z’olukusa ezigaziyiziddwa n’enkaayana z’okugabanya mu mateeka. Pulojekiti ezikwatibwa mu zooni enzirugavu ezitegeerekeka zisasula ssente za yinsuwa ezisingako ebitundu 15-20% okusinga pulojekiti ezisengekeddwa mu ngeri etegeerekeka obulungi-buli data ya Amwins Group. Abakola emirimu mu masaza agatali gamu bateebereza nti buli mwaka basaasaanya ddoola 500,000 nga batambulira mu nnyonyola ezitakwatagana. Ebisale ebigatta okuyita mu nkola yonna ey'omuwendo-abakola ebintu tebasobola kussa mutindo gwa bintu nga "enkola y'okutereka amaanyi ga bbaatule" etegeeza ebintu eby'enjawulo mu butale obw'enjawulo, ekiwaliriza oba yinginiya okusukkiridde okutuukiriza enzivuunula zonna ezisoboka oba dizayini ezenjawulo ez'akatale ezisaddaaka ebyenfuna by'omutindo.
Biki ebibaddewo mu byokwerinda ebivudde ku nnyonyola ezitategeerekeka ku kutereka bbaatule?
Omuliro ogwakwata Gateway Energy Storage mu San Diego (May 2024) gwalaga okutabulwa okw’ennyonnyola ng’ebitongole ebiddamu bituuse n’ebiragiro ebikontana nga byesigamiziddwa ku nteekateeka ez’enjawulo ez’okugabanya. Okubwatuka kwa McMicken mu Arizona (April 2019) okwalumya abazinya mwoto bana kwabaddewo ekitundu kubanga abaduumizi b’ebibaddewo baalwana okuzuula enkola ki ez’okuddamu ezikwata ku kifo kino. Okwekenenya kwa NERC okwa 2023 okw’olugendo lwa MW 498 olwava ku nsobi eya bulijjo-eyalongoosebwa kwazuula nti bambega mu kusooka tebaasobola kukkiriziganya oba okugigabanya ng’okulemererwa kw’eby’obugagga by’omulembe, ensonga y’eby’obugagga eyesigamiziddwa ku inverter-, oba enkola y’okutereka amaanyi obutakola bulungi-okulwawo okwekenneenya ebikolo ebivaako n’okussa mu nkola ebikolwa eby’okuziyiza. Ebintu bino tebyabaddewoolw'okubawa okutabulwa okw’ennyonnyola, naye okutabulwa kwakaluubiriza okuddamu okw’amangu n’okwekenneenya oluvannyuma -ebibaddewo.
Ennyonyola z’ensi yonna ezikwata ku kutereka bbaatule zirina omutindo okusinga ennyonyola za Amerika?
Si kya maanyi nnyo. Omutindo gwa IEC guwa enkola z’ensi yonna, naye okussa mu nkola kwawukana okusinziira ku nsi. Amawanga ga Bulaaya gajuliza emitendera gya EN egyawukana katono ku bikwata ku IEC. China erina omutindo gwayo ogwa GB/T ogw’okutereka amaanyi ogussa essira ku kussa mu nkola amangu n’okulinnyisa amakolero. Australia yakola emitendera gya AS/NZS egy’enjawulo ku mpisa zaabwe ez’omukutu. Bbanka y’ensi yonna yategeeza mu ndagiriro yaayo eya 2021 eya PPP ku kutereka bbaatule nti obutakwatagana mu nnyonyola bukiikirira ekiziyiza kinene eri ensimbi za pulojekiti mu nsi ezikyakula, ng’obutaba na bigambo bituufu ekizibuwalira okwekenneenya akabi n’okuwandiika yinsuwa. Amakolero geetaaga enkola ez’emitendera mingi ezisikiriza enjawulo mu bitundu ate nga zikuuma emisingi egy’ekikugu egy’awamu-egifaananako n’okuddukanya spectrum y’amasimu.
Obugezi obukozesebwa n’okukula kw’emigugu okuva mu bifo ebitereka amawulire binaakyusa engeri okutereka bbaatule gye kunnyonnyolwamu?
Yee, mu ngeri ey’amaanyi. Ebifo eby’amawulire ebyetaagisa okwesigika 24/7 n’amaanyi amangi bye bivuga obwetaavu bw’okutereka okumala ebbanga eddene-(essaawa 8-12 okusinziira ku mutindo gw’essaawa 2{8}}4 oguliwo kati) n’enkola ez’omugatte ezigatta kemiko za bbaatule eziwera ezirongooseddwa mu mbeera ez’enjawulo ez’okukozesa. Ebifo ebitendeka AI naddala byetaaga bbaatule zombi ez’amaanyi amangi-ez’ekiseera ekitono-okutereeza frequency n’enkola ez’ekiseera ekiwanvu okusobola okutereka amaanyi. Kino kisika ennyonyola okutuuka ku nsengeka ez’ebitundu ebingi ezikwata obusobozi bw’amaanyi (MW), obusobozi bw’amasoboza (MWh), n’obudde (essaawa) ng’ebipimo eby’enjawulo okusinga okuggya ebbanga okuva mu bibiri ebirala. Abaddukanya emikutu gya giridi batandise okugabanya okutereka okusinziira ku "duration bands" okusinga okutwala enkola zonna nga zenkanankana mu nkola awatali kulowooza ku bbanga lye zisobola okufulumya ku maanyi agagereddwa.
Kiki ekituuka ku pulojekiti eziriwo kati singa ennyonyola zikyuka nnyo?
Pulojekiti eziriwo zitera okufuna jjajja wansi w’ennyonnyola ezikozesebwa nga bafunye olukusa n’endagaano z’okuyunga. Naye enkyukakyuka mu nkola, okwongera ku busobozi, oba enkyukakyuka mu mbeera y’okukozesa kiyinza okuleeta okuddamu okugabanya wansi w’omutindo omupya. Kino kireeta okusika omuguwa wakati w’okutumbula omuwendo gw’eby’obugagga nga tuyita mu mirimu egy’enjawulo okusinziira ku kwewala okuddamu okugabanya mu ngeri ey’ennyonnyola ebiyinza okussaawo ebyetaago ebipya. Ennyonyola gye zikoma okukyuka awatali nteekateeka za nkyukakyuka zitegeerekeka, akabi k’okuteeka ssente mu kugoberera amateeka okusibikira gye kukoma. Endagaano za pulojekiti ezitunudde mu maaso kati zirimu obuwaayiro bwa "daptive definitions" obulaga engeri eby'obugagga gye binaasengekebwamu singa omutindo gukulaakulana-mu bukulu mu biseera eby'omu maaso-okukakasa endagaano z'enkyukakyuka mu nnyonyola ate nga zikuuma okugoberera amateeka agaliwo kati.
Amakolero gayinza gatya okugenda mu maaso n’okukwatagana obulungi mu nnyonyola?
Ekkubo erigenda mu maaso lirimu kaweefube ssatu akwatagana: (1) Ebitongole by’omutindo nga NFPA, IEEE, ne IEC okukwasaganya ku nsonga enkulu ez’omubiri ezikola omusingi ogw’awamu ate nga zikkiriza okubikka kw’ebiragiro ku nkola ezenjawulo; (2) Ebibiina by’abasuubuzi nga American Clean Power and Energy Storage Association ebitumbula okwettanira ebigambo ebituufu mu ngeri ey’obwannakyewa mu kkampuni zonna eza mmemba; ne (3) Obulagirizi bwa Federo okuyita mu DOE ne FERC okuteekawo enkola z’ennyonnyola ezisinga okwettanirwa ku pulojekiti ezifuna ensimbi za gavumenti eya wakati oba okwetaba mu butale wakati w’amasaza. Amateeka ag’ekyokulabirako ku mutendera gw’amasaza gayamba-Etteeka ly’ekyokulabirako erya New York erya 2020 lyayisibwa amawanga agatali gamu era ne litondawo waakiri okukwatagana kw’ebitundu. Naye okukwatagana okusembayo kwetaagisa abeetabye mu katale okulonda ennyonyola ezituukiridde ne bwe kiba nti amateeka tegaziragira, kubanga emigaso gy’emirimu egy’empuliziganya entegeerekeka gisinga enkizo yonna ey’ekiseera ekitono- okuva mu kusalawo okw’ennyonnyola.
Emitendera egiddako: Okutambulira mu buzibu bw’ennyonnyola obuliwo kati
Ennyonyola z'okutereka bbaatule zijja kusigala nga zikulaakulana-ekyo kikakasiddwa. Tekinologiya agenda mu maaso mangu nnyo nga enkola z'okulungamya teziyinza "kukwata" mu bujjuvu mu ngeri yonna ey'olubeerera. Naye abakola pulojekiti, abaddukanya, n’abakwatibwako tebeetaaga bumu bwa nnyonyola obutuukiridde okusobola okukulaakulana. Beetaaga obukodyo obw’omugaso okukola mu buzibu obuliwo kati ate nga banyigiriza okutuuka ku kukwatagana okutono. Eky'okuddamu ku "enkola y'okutereka amaanyi ga bbaatule kye ki" kiyinza okwawukana okusinziira ku mbeera, naye enkyukakyuka eyo esobola okuddukanyizibwa okusinga okuggyibwawo.
Ku bazimba:Zimba pulojekiti ng'okozesa enkola ya multi-layer specification ne bwe kiba nti abalungamya tebakyetaaga. Wandiika ebikwata ku by’obugagga ebirabika (Layer 1) ebitaliiko kugabanya mu mateeka (Layer 2) n’empeereza z’emirimu (Layer 3). Kino kifuula okukkiriza emboozi okutegeerekeka obulungi, kikendeeza ku butategeeragana n’abagaba ebyuma, era kiteeka pulojekiti mu kifo okukyusaamu singa ennyonyola zikyuka. Kozesa ennyonyola esinga okubeera enkakali okukozesebwa nga obutategeeragana buliwo-kigula ssente nnyingi mu maaso naye kyewala okuddamu okukyusa singa okutaputa kunywezebwa.
Ku bitundu ebifuga:Nga tonnaba kukola mateeka mapya agakwata ku kutereka bbaatule, kwataganya n’amasaza agaliraanyewo era weetegereze ennyonyola ki ebitundu ebiriraanyewo bye byassaawo. Okwewola enkola eziteereddwawo-ne ezitatuukiridde-kukuba okutondawo ennyonyola empya ddala eyongera okukutula obutale. Obulagirizi bwa NASEO obwa August 2024 ku nkola ya gavumenti ey’okutereka amaanyi buwa ebikozesebwa ebirungi ennyo. Naye ne bw’okozesa ebikozesebwa bino, laga emitendera egy’ebweru gy’ojuliza (NFPA 855, UL 9540, n’ebirala) okusinga okukola olulimi olulung’amya olukwatagana.
Ku bitongole ebivunaanyizibwa ku mutindo:Yanguya okukwasaganya mu IEEE, NFPA, IEC, ne ISO ku nnyonyola za parameter ez’omubiri ezikulu. Amakolero gasobola okusikiriza enjawulo mu byetaago by’obukuumi, enkola z’okugezesa, n’omutindo gw’emirimu kasita tukkiriziganya ku nsonga enkulu ng’engeri y’okupima obusobozi, amaanyi, ebbanga, n’obudde bw’okuddamu. Okufulumya ebifo ebisalako ebiraga engeri emitendera egy'enjawulo gye gikwataganamu-nga NFPA 855 ejuliza "enkola y'okutereka amaanyi agatali gakyukakyuka" ne IEC 62619 eyogera ku "obutoffaali obw'okubiri okukozesebwa mu makolero," okulambulula oba bannyonnyola ekintu kye kimu.
Omuliro gwa Gateway gwayaka okumala ennaku musanvu, kyokka eby’okuyiga ebivudde mu mbeera eyo bikyasaasaana nga biyita mu mulimu guno. Buli pulojekiti eyita mu kukkiriza eyigiriza abalungamya ekintu ekipya ku nnyonyola ki ezikola n’ezo ezireeta okusika omuguwa. Buli yinsuwa esaba erongoosa enkola z’okuwandiika. Buli nkaayana z’okuyunga abantu zisika abaddukanya emidumu okunnyonnyola enkola zaabwe ez’okugabanya. Okutabulwa kw'ennyonnyola tekujja kubula mu kiro kimu, naye kukyuka mpola okuva mu kavuyo okudda mu kavuyo akakola-si mutindo ogutuukiridde, naye kirungi ekimala okuleka tekinologiya okulinnya ku sipiidi gye twetaaga.
Okutereka bbaatule kusobola okuwa obusobozi emikutu egy’omulembe gye gyetaaga okugatta amasannyalaze agazzibwawo, okukuuma obwesigwa okuyita mu mbeera y’obudde embi, n’okuwagira okussa amasannyalaze ku mutendera. Naye singa tusobola okukkaanya obulungi ku bye twogerako okusobola okubiteeka mu nkola amangu okusinga bureaucracy bw’esobola okugikendeeza ku sipiidi. Ennyonyola zijja kusigala nga zikyukakyuka. Ekyo kirungi. Ekikulu kwe kuba nti zikulaakulana okutuuka ku kukwatagana mu kifo ky’okwongera okukutukakutuka.
Enkyukakyuka y’amasoboza tekyetaagisa bigambo bituukiridde. Kyetaaga ebigambo ebirungi ebimala okutambuza pulojekiti okuyita mu payipu z’okukkiriza mu myezi 18 mu kifo kya 36. Ekirungi ekimala okuleka obutale bwa yinsuwa okukola obulungi. Kirungi nnyo nti abazinya mwoto bamanyi kye baddamu nga bafunye essimu. Ekyo kituukirizibwa. Tutuukayo. Era buli mwezi ogw'enkulaakulana ey'okunnyonnyola yeegatta mu gigawatt-essaawa z'okutereka eziteekeddwa we kisinga okwetaagisa.
