Nsɛm a Wɔtaa Bisa
BESS betumi atew me anyinam ahoɔden ho ka so ahe ankasa?
Wɔn a wɔde di dwuma wɔ atrae no taa sie $500-1,200 afe biara denam bere-de-de arbitrage ne owia ankasa-de di dwuma yiyedi so. Aguadibea ahorow a wɔbɔ ka wɔ ahwehwɛde ho no hu $12,000-30,000 a wɔtew so afe biara denam ti nhwi a wɔbɔ no kɛse so. Nnwumayɛfoɔ a wɔde di dwuma wɔ gua a ɛsom boɔ -nya sika a wɔde sie $50,000-200,000+ a egyina adwumayɛbea kɛseɛ ne boɔ nhyehyɛeɛ so. Sikakorabea ankasa gyina wo utility no rate structure-time-of-use nsonsonoe, demand charge levels, ne net metering nhyehyeɛ na ɛkyerɛ boɔ a ɛbɛtumi agye.
Dɛn ne bere a wɔde tua ka ma BESS sika a wode asie?
Aguadi mu nneɛma a wɔde si hɔ no taa nya mfe 5-8 akatua bere a ne kɛse fata ma ahwehwɛde ho ka a wɔhwɛ so ne owia ahoɔden a wɔde yɛ adwuma yiye.

Sɛ wode 30% federal Investment Tax Credit no ka ho a, ɛtew payback so mfe 3-5 wɔ afã horow no nyinaa mu.
So ntease wɔ BESS mu sɛ minni solar panels a?
Wɔ atrae a wɔde di dwuma a wonni owia ahoɔden fam no, BESS sikasɛm gyina bere-a-de di dwuma dodow trɛw so koraa. Sɛ wo utility no gye $0.12/kWh off-peak ne $0.30/kWh wɔ-peak a, arbitrage hokwan ahorow wɔ hɔ. Sɛ wowɔ flat rates anaasɛ peak differentials kakraa bi ($0.15 vs $0.18), storage mfa sika biara a wɔtew so mma gye sɛ woakyerɛw wo din wɔ utility nhyehyɛe ahorow a wotua grid services ho ka (demand response, frequency regulation). Wɔn a wɔde di dwuma wɔ aguadi mu no bu BESS a owia ahoɔden nnim no bem denam ahwehwɛde ho ka a wɔhwɛ so nkutoo so sɛ ɛka boro $10/kW ɔsram biara a. Demand shaving value stream no nhia ahoɔden a wɔyɛ no foforo-batere a ɛregyae bere a wo facility no peak simma 15 no ara kwa.
Ɔkwan bɛn so na batere a ɛsɛe ne ɛka a wɔbɔ wɔ nsakrae ho no nya sika a wɔde sie bere tenten-?
Lithium iron phosphate batere a ɛyɛ papa no kura tumi 80-85% wɔ mfeɛ 10 a wɔde di sakre da biara da akyi, a egyina mprempren degradation curves so. Wei kyerɛ sɛ nhyehyɛeɛ a ne kɛseɛ de $1,000 bosome biara sikakorabea bɛma mfitiaseɛ no de $800-850 bosome biara sikakorabea ma wɔ afe 10.

So BESS nhyehyɛe ahorow betumi de wɔn ho ahyɛ nhyehyɛe ahorow a ɛma wonya sika foforo mu?
Yiw, na saa "stacked value streams" yi ma BESS sikasɛm kɔ so kɛse. Frequency regulation nhyehyɛe ahorow tua $5-15/kW afe biara ma nhyehyɛe ahorow a ɛyɛ wɔn ade wɔ grid frequency nsakrae ho. Nhyehyɛe ahorow a wɔyɛ de bua ahwehwɛde ahorow no tua $100-500 afe biara wɔ nhyehyɛe ahorow a wɔde tra atrae ho ne $5,000-20,000 ma aguadidan ahorow a wɔde si hɔ. Virtual Power Plant a wɔaboaboa ano no kyerɛw batere a ɛwɔ atrae mu wɔ ntam a wɔde di dwuma a wɔhwɛ so a wonya sika ɔsram biara. Tumi gua so kyɛfa a wonya wɔ gua akɛse a wɔahyehyɛ (PJM, CAISO, ERCOT) mu no ma wonya sika kɛse. Ade titiriw no: hwɛ hu sɛ wo BESS vendor ne installer no hyehyɛ nhyehyɛe ahorow ma program no fata na wɔde software nkabom ne utility platforms ma.
So asiane ahorow bi wɔ hɔ a ɛbɛma sikasɛm asesa bere a mahyɛ BESS awie no?
Utility rate nhyehyɛe ahorow no dannan ampa, na eyi de adwenem naayɛ ba. Bere-de-de di dwuma peak windows shift-California utilities ayɛ nsakrae wɔ peak periods mprɛnsa fi 2019. Ɛtɔ da bi a, demand charge structures sesa-tumidi kakraa bi a wɔtew per-kW charges so bere a ɛma ahoɔden dodow kɔ soro. Net metering nhyehyɛe ahorow hyia amammui mu nhyɛso a ɛkɔ so. Nanso, nsakraeɛ dodoɔ no ara wɔ rate mu no ba nkakrankakra wɔ bosome 12-24 amanneɛbɔ mu, na ɛma kwan ma wɔyɛ nsakraeɛ wɔ adwumayɛ mu.
