Dushingiye kuri raporo y’Ishirahamwe ry’Igihugu ry’Inguvu Zishobora Gusubirwamwo (NREL), n’ibiciro vy’ubushobozi bw’ibice vy’amabateri bihoraho, uko ubushobozi bwose bw’uburyo bwo kubika inguvu bugenda burakura, ni ko n’ibindi biguzi bigenewe igice c’ubushobozi kimwekimwe cose bigabanuka. Ivyo bituma Uburyo bwo Kubika Inguvu za Bateri (BESS) bugira akamaro kanini mu bikorwa vyo kubika inguvu z’ubushobozi bunini-, nk’uko vyerekanwa mu ndome iri musi.
Igiciro c'ububiko bw'inguvu za bateri ya litiyumu -ion
Mu buryo bwihariye, igiciro co gukora, gushiramwo no gukoresha BESS (Battery Energy Storage Systems) ziri mu bikoresho vyerekanywe mu ndome iri musi.
BESS Igiciro c'Igiciro (Imbonerahamwe 2-4)
| BESS Imirongo | Igikoresho/ Uruzitiro | Ivy'umuyagankuba | Ishusho | Gucungera ubushuhe | Uburinzi bw'umuriro | PCS (Ihindura) | Utugingo ngengabuzima twa bateri |
|---|---|---|---|---|---|---|---|
| 50kW/isaha zibiri | 4.3% | 11.3% | 8.7% | 3.4% | - | 7.5% | 64.8% |
| 250kW/isaha zibiri | 1.5% | 5.2% | 5.6% | 2.4% | 2.3% | 7.0% | 76.0% |
| 2500 kW/isaha zibiri | 0.7% | 2.5% | 2.0% | 1.3% | 1.0% | 5.0% | 87.5% |
Dufashe nk’akarorero BESS iri mu bikoresho ifise ubushobozi bwa 250kW/2h, amabateri azoba ari hafi 76% vy’igiciro cose; igikoresho, umugenzuzi wo mu karere, umugenzuzi w’ubushuhe, uburinzi bw’umuriro, ugusangira amashanyarazi, n’ibindi bikoresho bijanye (amatara, intsinga, n’ibindi) bizoba bifise hafi 15,5%; kandi PCS izogira hafi 7%. Ariko rero, umuhinduzi w'uruzitiro-huye ntabwo ari muri iyo sisitemu iri hejuru.
Birashobora kubonwa ko, uhereye ku bijanye n’ibiciro vy’ibikoresho n’ivy’uguhingura, uko ubushobozi n’ububasha bw’uburyo bwo kubika inguvu biguma vyiyongera, igice c’ibiciro vy’uburyo bwo guhindura inguvu (PCS) n’ibindi bihimba vy’umuyagankuba n’imibumbe kizogabanuka bivanye n’ivyo, mu gihe igice c’ibiciro vy’amabateri kizoguma kigwira. Ku bw’ivyo, kugenzura igiciro c’amabateri bizogira ingaruka zikomeye ku kugabanya igiciro cose c’ibikoresho vyo kubika inguvu z’amabateri (BESS).
