Okutereka bbaatule za faamu y’enjuba kuyinza okuteekebwa mu nkola oba nga zisangibwa wamu n’ebifo ebiteekebwamu amasannyalaze g’enjuba oba ng’ebifo ebyetongodde okumpi n’ebizimbe by’amasannyalaze. Ekifo kisinziira ku kumpi n’okuyungibwa ku mudumu, engeri y’ettaka, n’okumanya oba pulojekiti egenderera okutumbula enkola y’okukola amasannyalaze g’enjuba oba okuwa obuweereza obwetongodde ku mudumu.
Enkola bbiri ez’okuteeka mu nkola ze zifuga akatale. Enkola ezisangibwa awamu ziteeka okutereka bbaatule za ffaamu z’enjuba butereevu mu bifo ebikola amasannyalaze, nga zikozesa enkola y’okufulumya ebiriraanyewo okukendeeza ku nsaasaanya y’okuyunga n’okusobozesa okukyusakyusa amaanyi mu ngeri ennungi. Ekifo kya Edwards Sanborn mu California kiwa ekyokulabirako ky’enkola eno nga kirimu amasannyalaze g’enjuba aga MW 875 nga gagatta wamu n’amasannyalaze ga MWh 3,300. Ebifo bya bbaatule ebyetongodde, okwawukana ku ekyo, bikola nga byetongodde okuva ku nsonda z’omulembe era biyungibwa butereevu ku mudumu (grid) awali empeereza y’okutebenkeza esinga okwetaagisa. New York yaggulawo ekifo kyayo ekisooka ekya gavumenti-ekyetongodde mu Franklin County mu 2023, nga kiraga obusobozi bw’ebikozesebwa eby’okutereka eby’enjawulo.
Ebyetaago by’okuyunga Grid Drive Okusalawo ku kifo
Okubeera okumpi n’ebikozesebwa mu kutambuza amasannyalaze kye kisalawo ebyenfuna bya pulojekiti ku kutereka bbaatule za faamu y’amasannyalaze g’enjuba. Okutereka bbaatule kyetaagisa okutuuka butereevu ku layini ssatu-okusaasaanya phase, ekisinga obulungi mu ffuuti 1,000 okusobola okuyungibwa okutali kwa ssente-. Ebanga erigenda ku siteegi entonotono likwata kyenkanyi-abakola emirimu batunuulira ebifo ebiri mu mayiro 2 okukendeeza ku nsaasaanya y’okuyungagana eyinza okutuuka ku doola 500,000 buli mayiro mu Bukiikakkono bw’obuvanjuba bwa Amerika ku bifo ebigabula amasannyalaze ebya kV 12-32.4.
Ebiziyiza obusobozi bwa grid byongera okubumba okuteekebwa mu nkola. Ennyiriri z’okuyunga abantu mu Amerika zaali zirina GW 2,600 ez’obusobozi obuteeseddwa ku nkomerero ya 2023, nga bbaatule zikola ebitundu 46% ku pulojekiti ezinoonya okuyungibwa ku mudumu gwa CAISO. Ebipimo by’obusobozi bw’okutambuza ebiriwo (ATC) biraga oba ebikozesebwa ebiriwo bisobola okusuza okutereka okupya awatali kulongoosa kwa ssente nnyingi. Ebiwandiiko ebikwata ku miwendo egy’oku mabbali mu kifo (LMP) biraga ebitundu eby’okusalawo kw’amasoboza we biwa ensimbi ezisinga obungi, kubanga enjawulo mu miwendo wakati w’ebiseera by’okusasula n’okufulumya zikwata butereevu ku magoba.
Abaddukanya emikutu gy’okusaasaanya (DNOs) bateekawo ebisaanyizo eby’ekikugu ebyawukana okusinziira ku buyinza. Amateeka ga California aga Limited Generation Profile kati galagira okukwasaganya enteekateeka ku pulojekiti z’okutereka amasannyalaze g’enjuba-plus-, okukendeeza ku butabeera mu ntebenkevu bwa giridi okuva ku by’amaguzi ebikyukakyuka ebweru w’eggwanga. Abakola pulojekiti balina okukuuma okusaba kwa G99 ku nkola ezisukka mu kW 3.68 buli mutendera, nga kuzingiramu okuweebwayo okw’ekikugu mu bujjuvu n’okunoonyereza ku ngeri enkosaamu okuyinza okwongera ku biseera okutuuka ku nnaku 20 ez’omulimu oba okusingawo.
Engeri z’Ekifo Ekirabika
Minzaani y’ebyetaago by’ettaka n’obusobozi. Faamu y’amasannyalaze g’enjuba eya MW 1 mu bujjuvu yeetaaga yiika 5-7, ng’okutereka bbaatule kwongera ku busobozi bwa MW 200-400 ku buli MW 500 ez’amasannyalaze g’enjuba. Pulojekiti ez’omutindo gw’ebikozesebwa zeetaaga yiika 200+ okuteekebwamu amaanyi agasukka mu MW 20. Ab’obuyinza mu bitundu bakugira okubikka ebifo mu bujjuvu, nga bakkiriza ebitundu nga 60% ku yiika zonna okuteekebwa mu nkola ebipande n’ebyuma oluvannyuma lw’okubala ebizibu ebiddirira n’ebitundu ebikuuma.
Enkula y’ensi ekwata ku nsaasaanya y’okussaako n’obulungi bw’emirimu gy’okutereka bbaatule za faamu y’amasannyalaze g’enjuba. Ebiserengeto ebipapajjo oba ebitunudde mu bukiikaddyo-mpola (wansi wa diguli 5) bitereeza okulabika kw’enjuba ate nga byanguyira okuzimba. Obuserengeto obutono obw’ebuvanjuba oba obw’obugwanjuba busobola okutumbula okukwata amaanyi g’oku makya. Ebifo ebirina enjawulo ennene mu ddaala, ebiserengeto ebiwanvu ebitunudde mu bukiikakkono-, oba obusozi obuyiringisibwa byetaaga omulimu gw’ettaka ogulinnyisa embalirira ya pulojekiti. Ebintu ebiteekebwamu bbaatule byetaaga emisingi gya seminti egy’omutindo ogusobola okuwanirira yuniti za modula eza ffuuti 40- ezirimu obutoffaali bwa lithium-ion.
Okutebenkera kw’ettaka kuziyiza ebizimbe okulemererwa. Embeera y’ettaka erina okuwagira enkola z’okussaako awatali kusenza kususse. Okufulumya amazzi amalungi kikuuma obutakulugguka kw’ettaka obuyinza okwonoona emisingi oba okubooga ebyuma by’amasannyalaze. Ebitongole bya gavumenti eya wakati okukola maapu y’ebifo ebikulukutiramu amataba n’entobazzi-okuzimba mu bitundu by’amataba eby’emyaka 100 oba 500 kireeta okunoonyereza okulala okutuufu, ate ng’obukwakkulizo ku ntobazzi busobola okuyimiriza ddala pulojekiti.
Okukebera obutonde bw’ensi kuzuula eby’obugagga ebikuumibwa nga tebannaba kukulaakulanya. Ebifo ebika by’ebisolo ebiri mu katyabaga k’okusaanawo, ebifo eby’ebyafaayo, n’ebitundu by’obutonde ebikuumibwa bitondekawo ebitundu ebitaliimu. Ebifo ebiri mu ppaaka z’eggwanga, ebifo ebikuumirwamu obutonde, oba Ebitundu eby’Obulungi bw’Obutonde Obw’enjawulo byolekedde ebizibu ebiragirwa. Abawi b’amagezi ku butonde bw’ensi batuusa lipoota z’okwekenneenya mu wiiki 4-6, wadde ng’ebikozesebwa bya digito kati binyigiriza ekiseera kino okutuuka ku ddakiika okusobola okwekenneenya okusooka.
Ebilowoozebwako mu kulungamya n’okugabanya ebitundu
Okukkiriza okuzibuwalirwa kwawukana okusinziira ku buyinza. Ettaka lirina okuteekebwa mu zooni okukola pulojekiti ez’omutindo gw’amasannyalaze agazzibwawo oba ez’omugaso-, nga ensengeka z’ebyobulimi ze zisalawo obusobozi. Ettaka lya Bungereza "erisinga obulungi era erisinga okukola ebintu bingi" n'ettaka ly'ebyobulimi erya Scotland "ery'omugaso ennyo" byolekedde okuziyiza enkulaakulana, wadde ng'okunyigirizibwa kw'ebbula oluusi kuwaliriza okukyukakyuka. Enteekateeka ya California eya Opt-In Certification erongoosa okukkirizibwa, eragira okwekenneenya obutonde bw’ensi okumala ennaku 270 okuggyako ng’enkyukakyuka ennene ziyongedde ku biseera.
Okubeera okumpi n‟ekitundu kubumba okukkirizibwa kwa pulojekiti. Ebintu ebifuuwa empewo mu kifo we batereka bbaatule bikola amaloboozi ageetaagisa okuziyiza amaloboozi okumpi n’ebifo omubeera abantu. Endowooza y’abantu eyawukana wakati w’abawagizi b’enkyukakyuka y’obudde n’abawagizi b’okukuuma ebifo. Abakulaakulanya balina okukwatagana n’ebitundu mu ngeri ey’obwegendereza, kubanga abavuganya mu kitundu basobola okuggya pulojekiti ku luguudo mu nkola z’okukkiriza. Olukiiko lw’ekibuga York lwagaana ekyuma kya bbaatule za yuniti 104 mu December wa 2024 nga bagamba nti waliwo okweraliikirira obukuumi bw’omuliro n’omusipi omubisi wadde nga kigasa obutonde bw’ensi.
Enkola z’okuzimba ze zilagira omutindo gw’eby’ekikugu. Ennyingo 690, 705, 706, ne 710 mu tteeka ly’amasannyalaze mu ggwanga (NEC) zifuga enjuba-plus-okutereka enkolagana. Breakers ne disconnects zeetaaga 125% oversizing okusinziira ku maximum inverter output, ate renewable source output tesobola kusukka 120% ku main service panel bus ratings ku load-side connections. California yazza obuggya etteeka lyayo erikwata ku muliro mu March 2025 okussaamu omutindo gwa NFPA 855 (2023 edition), nga kikakatako okugoberera mu January 2026.
Obukuumi n’okwetegekera embeera ez’amangu
Lithium-ion thermal runaway eraga akabi akasookerwako mu nkola z’okutereka bbaatule za faamu z’enjuba. Obutoffaali obubuguma ennyo buleeta ensengekera z’amazzi agakulukuta (cascading reactions) nga bufulumya ggaasi za haidrojeni ne methane eziyinza okukuma omuliro oba okubwatuka. Ekifo kino ekya Moss Landing kyakwata omuliro mu 2022 ate nate mu January wa 2025, ne kisengula abatuuze 1,200 okumala essaawa 24. Amakolero gakyuse ne gagenda mu bidomola ebiziyiza omuliro ebya modulo nga biriko amabanga agatali ga bulabe ag’okwawula, ne kikendeeza ku bulabe bw’okusaasaana wakati wa yuniti za bbaatule.
Okuziyiza omuliro kusoomooza abasooka okuddamu. Omuliro gwa lithium-ion gwokya nnyo, guziyiza enkola eza bulijjo ez’okuzikiza, era gusobola okuddamu okukwata oluvannyuma lw’ennaku. Ebiragiro eby’amangu bigamba nti ebifo eby’okwekutula ku ffuuti 330-ebifo ebinene eby’obusuubuzi, okuteeka abadduukirize waggulu w’empewo n’okulinnya. Ebyuma ebissa ebyezo-ebikuuma obutwa obufuluma. Pulofeesa wa Cornell Max Zhang assa essira ku kukwasaganya emirimu nga tegunnabaawo: "Kikulu okuleeta ekitongole ekizikiriza omuliro mu bwangu, ku mmeeri. Kubanga akabenje bwe kamala okubaawo, tebeeyisa ng'omuliro ogwa bulijjo."
Enkola z'okuddukanya bbaatule (BMS) ziwa obukuumi obusookerwako okuyita mu kulondoola ku ddaala ly'obutoffaali okuziyiza embeera z'okukola ezisukkiridde-. Enkola z’okuddukanya amaanyi (EMS) zeekenneenya ebikwata ku bantu okuzuula obuzibu nga bukyali. Bombi balina okugoberera omutindo gw’obukuumi ogw’emirimu ogwa IEC 61508. Ebisenge bya kabineti ebisengekeddwamu nga biriko ebiziyiza ebbugumu birimu okulemererwa ate nga bikuuma ebbugumu erisinga obulungi erya diguli 20-23. Okulondoola okw’omulembe kuteeka mu nkola kkamera za infrared ne sensa z’ebbugumu okusobola okuzuula akabi mu kiseera ekituufu.
Ekibiina kya California ekya 2024 State Battery Storage Safety Collaborative kikwasaganya okulondoola kw’ebitongole ebingi-nga kiyita mu CARB, CEC, CPUC, CAL FIRE, n’empeereza ez’amangu. Ekiragiro kya CPUC ekya General Order 167-C kati kikwata ku ndabirira ya bbaatule n’emirimu, okukakasa nti enteekateeka z’okukola mu mbeera ez’amangu zituuka mu bitongole ebizikiriza omuliro mu kitundu. Pulojekiti ezikolebwa ku mutindo gwa grid zirina okussa mu nkola okugoberera NFPA 855, okulondoola omutindo gw’empewo n’amazzi obutasalako, n’okutendeka abasooka okuddamu okugenda mu maaso. Pulojekiti y’amasannyalaze amayonjo eya Darden eyayisibwa mu 2025 ng’erina amasannyalaze g’enjuba aga MW 1,150 n’okutereka amasannyalaze ga MWh 4,600, eraga ekyokulabirako ky’omutindo guno ogwongezeddwayo.
Enkyukakyuka mu katale n’ebyenfuna bya pulojekiti
Okukendeeza ku nsaasaanya kwayanguyiza okuteeka mu nkola eby’okutereka bbaatule za ffaamu ez’amasannyalaze g’enjuba. Ensaasaanya y’amasannyalaze g’enjuba ku mutendera gwa Utility-yakendeera ebitundu 90% mu myaka kkumi egiyise okusinziira ku Ørsted, ate ssente z’okutereka bbaatule zakendedde emirundi 2-3x okuva ku mitendera gya 2020 ng’okukendeera okulala okusuubirwa okutuuka mu 2050. Etteeka erikendeeza ku bbeeyi y’ebintu (IRA) lyaleeta okukendeeza ku musolo gw’okusiga ensimbi ku kutereka ebintu okwetongodde mu August 2022, nga edda byali bya kutereka bbaatule byokka ensengekera z’enjuba. Enkyukakyuka eno mu nkola yaleetawo okusaba kw’okuyungibwa kw’amasannyalaze g’enjuba, okutereka, n’empewo okuva IRA lwe yayisibwa.
Okuyingiza ensimbi kubaawo nga bayita mu mikutu mingi. Energy arbitrage ekwata enjawulo z’emiwendo-bbaatule ezisasula mu biseera eby’obwetaavu obutono-nga zikola enjuba nnyingi n’okufulumya mu biseera by’obwetaavu obw’oku ntikko akawungeezi ng’emiwendo girinnya okuva ku -£70 okutuuka ku +£200 buli MWh mu butale bwa Bungereza. Empeereza za grid ziwa ensimbi eziyingira mu kulungamya frequency, nga abaddukanya basasula bbaatule okubuffer supply-demand fluctuations okukuuma 50 Hz stability. Obutale bw’obusobozi buliyirira okutereka olw’okulaba ng’ebitereke by’amasannyalaze ebimala ku ntikko biweebwa mu buwangwa amakolero g’amafuta g’ebintu ebikadde.
California ne Texas ze zisinga okuyisibwa mu Amerika. Amasaza gano gaali gakola ebitundu 82% ku busobozi bwa bbaatule obwa GW 14.3 obwali busuubirwa okugattibwa mu 2024, nga California etuuse ku MW ezisukka mu 13,300 omugatte ku nkomerero y’omwaka-(20% ku bwetaavu obw’oku ntikko). Pulojekiti za CAISO zeetaaga GW 165.1 ez’omulembe omupya omuli GW 58 ez’okutereka omwaka 2045 we gunaatuukira okusobola okutuukiriza ebiruubirirwa by’amasannyalaze agazzibwawo 100% mu katale. Akatale ka bbaatule ku mutindo gwa grid- mu nsi yonna kagenda kutuuka ku buwumbi bwa ddoola 31.2 omwaka 2029 we gunaatuukira okusinziira ku basenserezi b’amakolero.
Okulonda Enkola y’okuteeka mu nkola
Co-located configurations excel awali okutumbula enkozesa y’enjuba kikulu. Okubeera okumpi n’okukola amasannyalaze kikendeeza ku nsaasaanya y’amasannyalaze mu kiseera ky’okucaajinga emisana-Ebiwandiiko bya CAISO biraga nti bbaatule ezisangibwa co-zifuna amagoba mangi okuva mu arbitrage olw’ebbeeyi y’emisana okukka okumpi ne faamu z’amasannyalaze g’enjuba. Enkola ezisangibwa awamu ziwa amaanyi mangi n’obuweereza obuyambi obutono buli MW bw’ogeraageranya n’ebifo ebyetongodde. Pulojekiti ya Eleven Mile Solar mu Arizona eraga enkola eno ng’erina amasannyalaze g’enjuba aga MW 300 n’okutereka amasannyalaze ga MWh 1,200 nga gawa enzirukanya y’okufulumya amazzi mu ssaawa nnya-buli lunaku.
Ebifo ebiyimiriddewo bitereeza empeereza y’okutebenkeza omukutu. Texas yateeka enkola zino okukola ku mbeera ez’amangu eza February 2024, n’eyongera ku bungi bw’okutereka kumpi GW emu. Battery eziyimiridde zituusa obuweereza obuyambi obusingawo nga ziyita mu biseera eby’okuddamu amangu ekisobozesa okulungamya frequency eya subsecond. Bazuula awali omugotteko gwa emikutu oba okwesigamizibwa kwe kulaga obutuufu bw’ebikozesebwa ebiweereddwayo nga tebirina budde bwa kukola. California eddukanya ebifo bisatu ebyetongodde mu ssaza lyonna omuli n’okuteekebwa mu Franklin County.
Okwagala pulojekiti ya Hybrid kweyongedde mu bitundu. CAISO ne non-ISO Western interconnections ziteesa ku bitundu 98% ne 81% ku busobozi bw’enjuba mu nsengeka z’omugatte, nga zonna awamu 571 GW ez’obusobozi bw’enjuba ez’omugatte mu nnyiriri za Amerika. Okugatta omulembe n’okutereka okusangibwa awamu kyongera omuwendo gw’akatale n’okukyukakyuka naddala mu bitundu ebiyingira ennyo ebizzibwa obuggya. Battery ezisinga mu CAISO zikola n’obudde bwa ssaawa 4-nga zituukira ddala ku arbitrage mu lunaku, wadde nga enkola eziwangaala ennyo zigenda zivaayo olw’obwetaavu bw’okutereka mu sizoni.
Okulowooza ku mbeera y’obudde n’ebifo
Omutindo gw’eby’obugagga by’enjuba gukwata ku busobozi bwa pulojekiti. Ekitundu ky’eddungu lya Mojave kifuna ebimu ku bitangaala by’enjuba ebisinga obuwanvu ku ttaka-mu Amerika, ekisobozesa ebifo nga Edwards Sanborn okutumbula omulembe. Naye, ebbugumu erisukkiridde lireeta okusoomoozebwa-ebbugumu eriwangaala liyinza okukendeeza ku mutindo gwa panel n’okwanguyiza okukaddiwa kwa bbaatule. Embeera y’obudde ennungi bbalansiza obusannyalazo obw’amaanyi n’ebbugumu ery’ekigero olw’obuwangaazi bw’ebyuma.
Okuyingira kw’amasannyalaze agazzibwawo mu bitundu kukosa omuwendo gw’okutereka. Ebitundu ebirina eby’obugagga ebizzibwawo ebikyukakyuka bifuna emigaso mingi okuva mu buffering ya bbaatule ekigonza enkyukakyuka mu mulembe. Professor Max Zhang annyonnyola nti: "N'okutereka bbaatule, okusinga osobola okufuula omulembe ogukyukakyuka mu mulembe oguteeberezebwa ennyo ng'okola nga buffer." Ebizinga nga Hawaii byesigamye nnyo ku kutereka amasannyalaze g’enjuba-plus- okusinziira ku ngeri endala ezikozesebwa mu mafuta g’ebintu ebikadde-ekifo kya Mililani Solar kiwa enkola ya O’ahu esooka ey’okukozesa-scale combined system n’obusobozi bwa MW 39.
Engeri z’okuyungagana zaawukana mu bitundu. Western Interconnection esobola okutuuka ku bitundu 33% okuyingira kw’empewo n’enjuba awatali kutereka kwongerako okusinziira ku kunoonyereza okwakolebwa mu 2013, wadde ng’ekiseera kya California eky’okuggya kaboni mu ngeri ey’amaanyi kyetaagisa okuteekebwa mu nkola amangu okutereka. Buyindi eyinza okussaamu GW 160 ez’empewo n’enjuba (22% okuyingira) nga tezirina byetaago by’okutereka, naye ebiruubirirwa by’ensi yonna eby’okukyusa amaanyi byanguya ebiseera by’okugatwala.
Enkozesa y’ettaka n’okukosa abantu
Okuddamu okukozesa ettaka ly’ebyobulimi kireeta okusika omuguwa. Ettaka ly’ennimiro erya Prime lyolekedde okuziyiza enkulaakulana, ate ettaka ery’oku mabbali eritasaana kulimibwa lisikiriza pulojekiti z’amasannyalaze g’enjuba. Pulojekiti ya Darden Clean Energy ekozesa yiika 9,500 mu maserengeta ga Fresno County nga tekyawagira kukola bya bulimi. Enkola za agrivoltaic zisobozesa okulima ebirime wansi w’ebipande ebigulumivu, ne kisobozesa okukozesa ettaka emirundi ebiri ekikuuma ensimbi eziyingira mu bulimi ate nga kyongera ku nsimbi eziyingira mu masannyalaze.
Ebyenfuna bya bannannyini ttaka bivuga okwetabamu. Liizi z’ettaka ly’enjuba ziyingiza pawundi 800-1,200 buli yiika buli mwaka mu Bungereza, nga ziwa ssente ezitakyukakyuka nga tezikwata ku makungula g’ebirime agakoseddwa embeera y’obudde-. Pulojekiti z’Amerika zituusa amagoba agafaananako bwe gatyo-Ørsted’s Eleven Mile Solar egaba obukadde bwa ddoola 5.6 mu nsasula ya bannannyini ttaka buli mwaka n’emisolo ku bintu. Endagaano za liizi ez’ekiseera ekiwanvu (emyaka 20-40) zeetaaga bannannyini ttaka okweyama okugaziyizibwa, wadde ng’okutebenkera kw’enyingiza kusikiriza abo aboolekedde okukoma ku ddembe ly’amazzi oba ettaka eritali lya bibala.
Ebyetaago by’emikisa gy’abantu b’omukitundu byongera okukkirizibwa. California’s Opt-In Certification eragira okuteeka ssente mu ggwanga-pulojekiti ya Darden yeeyama obukadde bwa ddoola bubiri mu myaka kkumi nga kuliko ddoola 320,000 eri Centro La Familia Advocacy Services. Pulojekiti zitondawo emirimu 2,000+ egy’okuzimba egy’omusaala- egy’omusaala mu biseera by’okuzimba eby’emyaka 1.5-3. Abazimba essira balitadde ku kukuuma ebifo ebibeera abantu n’okubiggyawo mu bujjuvu nga baddamu okukozesa amasannyalaze g’enjuba n’okuzzaawo ettaka nga liizi ziweddeko.
Ebibuuzo Ebitera Okubuuzibwa
Okutereka bbaatule kuyinza okugattibwa ku faamu z’amasannyalaze g’enjuba eziriwo?
Okuddaabiriza bbaatule kisobozesa okugatta okutereka amaanyi mu bifo ebikola amasannyalaze g’enjuba. Rosamond Central Solar eya California yatandika okukola mu 2021, nga oluvannyuma yayongerwako enkola ya bbaatule ya MW 147 okutereka n’okukyusa omulembe. Pulojekiti z’okuddamu okulongoosa zeewala ssente ezisaasaanyizibwa mu kuyungibwa ku nkolagana nga zikozesa okuyungibwa kw’omukutu oguliwo, wadde ng’ekifo n’okukwatagana kw’ebyuma byetaaga okwekenneenya. Emigaso gya co-location gituukirira awatali kuddamu kuzimba biteekebwa byonna.
Lukusa ki olwetaagisa okuteeka mu nkola okutereka bbaatule za ffaamu z’amasannyalaze g’enjuba?
Enkola z’okuyunga giridi (G98, G99, oba G100) ziteekawo olukusa lw’okuyunga okuva mu Baddukanya Emikutu gy’Okusaasaanya. Olukusa lw’okuzimba lukakasa okugoberera enkola z’amasannyalaze eza munisipaali n’ennyingo za NEC. Olukusa lw’obutonde lukwata ku kukuuma enzizi, okulowooza ku bika ebiri mu katyabaga k’okusaanawo, n’omutindo gw’empewo/amazzi. Olukusa lwa Fire Marshal lukakasa nti NFPA 855 etuukana omuli enkola z’okufuuwa amazzi, empewo, n’okuyingira mu mbeera ez’amangu. Olukusa lw’okugabanya zoni kukakasa enkozesa y’ettaka ekwatagana n’enkulaakulana y’amasannyalaze agazzibwawo.
Abakola bapima batya obusobozi bwa grid ku pulojekiti z’okutereka?
Ebipimo by’obusobozi bw’okutambuza ebiriwo (ATC) bye bisalawo obungi bw’emikutu gy’okutambuza amaanyi bwe giyinza okwesigika nga gikuuma emigabo gy’obukuumi. Abakola ebyuma byekenneenya ebikwata ku siteegi omuli emitendera gya vvulovumenti, omugugu oguliwo, n’ebyetaago by’okulongoosa. Data y’ennyiriri z’okuyungibwa (interconnection queue data) eraga pulojekiti ezivuganya nga zinoonya okuyingira ku mudumu gwe gumu. Okunoonyereza ku kutambula kw’amasannyalaze model system impacts wansi w’embeera ez’enjawulo ez’emirimu. Abaddukanya emikutu gy’empuliziganya bawa amawulire agakwata ku busobozi, wadde ng’obutali bukakafu bubaawo nga pulojekiti eziri mu nnyiriri zigenda mu maaso oba nga ziggyibwawo ekikosa obusobozi obwennyini obuliwo.
Kiki ekituuka ku nkola z’okutereka bbaatule ku nkomerero y’obulamu?
Battery za lithium-ion zisigaza obusobozi bwa 70-80% oluvannyuma lw’emyaka 10-15 nga zikola ku ggirita. Okukozesa okw’okubiri kwongera ku bulamu obw’omugaso nga bayita mu kuzzaawo ekigendererwa mu mirimu egitasaba nnyo. Enkola z’okuddamu okukola ebintu zizzaawo lithium, cobalt, nickel, n’ebintu ebirala eby’omuwendo, wadde ng’ebizimbe bikyali tebikulaakulana okusinziira ku nkula y’okuteekebwa mu nkola. Ebiragiro ebikwata ku butonde bw’ensi byeyongera okulagira enteekateeka z’okutwala-back n’enkola entuufu ey’okusuula.
