FAQ
Panon karakel so baterya ya kaukolan ko parad peak shaving?
Iparaan so kW na discharge na baterya ed katagey na paulit-ulit ya peak ed tagey na target ya kisame, tan iparis so kWh to ed sankabayagan ya tuloytuloy ya peak tan 15% anggad 20% ya reserba. Mas importante so power rating nen say kapasidad.
Kapigan so solar-only peak shaving ya onsaew?
Ag-itan ontalona no saray peak et nagawa kayari na iselek na banwa, legan na saray ebento na lurem, odino diad antikey iran panagputok ya mas maples nen say nayarian na PV. Ag-itan ontalona no say PV size et melag no ikompara ed spike, odino no say interval data et agto nakumpirma so overlap na solar production tan saray site peaks.
Sulit kasi so peak shaving no say tariff ko et anggapoy demand charge?
Aliwan on demand-charge economics labat. Balet say panag-imbantak et makabayar nin siansia diad panamegley na panaon-na-pangusar na arbitrage, solar self-consumption, tan backup value. Dakel ya utilities so mangaarum na demand charges ed C&I tariffs, kanian say tepet et mabetbet ya "kapigan," aliwan "no."
Antoy kabaleg na baterya so kaslakan ed C&I peak shaving project?
Maslak ed saray melag ya anggad kapegleyan ya komersyal ya proyekto et walad baetan na 100 kW / 200 kWh tan 500 kW / 1 MWh. Saray industrial site ya baleg so proseso da et nayarin mankaukolan na 1 anggad 5 MWh. Say suston kabaleg et manlalapud interval data, aliwan manlalapud saray totontonen.
Antoy pidumaan na peak shaving ed load shifting?
Say peak shaving et mamawas ed sankatageyan ya kW ya naala ed grid tan manpuntirya ed saray demand charges. Say load shifting et mangigalaw ed kWh ya konsumo ed baetan na saray panaon tan manpuntirya ed panaon-na-usar na enerhiya. Say sisteman maong ya indesinyo et mabetbet ya manggagawa ed saratan ya dua.
