New eco-friendly power op­tions with lithium-ion home stor­age bat­tery sys­tem

DEMM Engineering & Manufacturing - - ELECTRICAL TECHNOLOGY -

Pana­sonic New Zealand has launched its first Lithi­u­mion home stor­age bat­tery – a clever sys­tem that can sense and store ex­cess clean so­lar en­ergy to power house­holds in the evening once the so­lar sys­tem has stopped pro­duc­ing, says the com­pany, but also al­lows a util­ity or sys­tem in­te­gra­tor to link to­gether bat­tery sys­tems at var­i­ous lo­ca­tions to form a vir­tual power plant. This can help shift peak loads and can have fi­nan­cial ad­van­tages for both the util­ity as well as the home owner.

This smart bat­tery sys­tem pro­vides a revo­lu­tion­ary and en­vi­ron­men­tally re­spon­si­ble so­lu­tion to use so­lar en­ergy on de­mand, prom­ises Pana­sonic. New Zealand al­ready has more than 8,000 homes with so­lar pan­els and this tech­nol­ogy gives owner’s free­dom to choose their en­ergy source, man­age their en­ergy use and costs, in ad­di­tion to pro­vid­ing an ex­tra layer of crit­i­cal en­ergy se­cu­rity dur­ing power out­ages.

Pana­sonic’s Home Stor­age Bat­tery sys­tem also of­fers a unique so­lu­tion for New Zealand en­ergy dis­trib­u­tors. The bat­ter­ies can be re­motely con­trolled by an ag­gre­gated ser­vice provider, in­clud­ing util­i­ties and en­ergy com­mu­ni­ties, to re­duce grid in­fra­struc­ture ex­penses and bet­ter man­age en­ergy us­age at peak times. This fea­ture will help sta­bilise the grid by re­duc­ing so­lar sys­tem ex­port dur­ing low de­mand times and sup­ply it dur­ing peak times, such as in the evening. Many stake­hold­ers and in­ter­ested par­ties such as Trans­power are in­ves­ti­gat­ing tech­nolo­gies to help them bet­ter man­age ex­ist­ing in­fra­struc­ture and Pana­sonic are per­fectly placed to help with this easy to in­stall and scal­able so­lu­tion.

Pana­sonic New Zealand’s Man­ag­ing Di­rec­tor Ste­wart Fowler is ex­cited by the growth and use of so­lar power sys­tems in New Zealand and is proud to be at the cut­ting edge of the ex­cit­ing new tech­nol­ogy of home stor­age bat­tery sys­tems, which is widely re­garded as the miss­ing link to truly ful­fil the po­ten­tial of so­lar power sys­tems.

“For the thou­sands of Ki­wis who al­ready gen­er­ate their own so­lar power this is a dream come true, so we’re in­cred­i­bly ex­cited to bring this so­lu­tion to New Zealand. We want to en­cour­age Ki­wis to take con­trol over their power. The Pana­sonic Home Stor­age Bat­tery Sys­tem in con­junc­tion with a so­lar power sys­tem could help an av­er­age New Zealand house­hold to re­duce their power pur­chase by up to 60 per­cent. We be­lieve this is the way for­ward for sus­tain­able en­ergy con­sump­tion.

“This sys­tem isn’t lim­ited to those who have so­lar pan­els. Con­sumers can use it to take ad­van­tage of favourable power prices dur­ing off-peak times or as an emer­gency power source for crit­i­cal ap­pli­ances. En­ergy providers can use it to meet fluc­tu­at­ing en­ergy de­mands by us­ing our smart de­mand re­sponse so­lu­tions, with­out hav­ing to in­vest in fur­ther in­fra­struc­ture,” says Fowler.

Pana­sonic is a world lead­ing lithium-ion bat­tery man­u­fac­turer and for the past 40 years has been in­vest­ing heav­ily in re­search and cre­at­ing in­no­va­tive bat­ter­ies that pro­vide a sta­ble power sup­ply that is re­li­able, high qual­ity, high per­for­mance and safe in ex­treme con­di­tions.

The slim home stor­age bat­tery sys­tem looks sim­i­lar to a heat pump out­door unit and is a low-main­te­nance, stand­alone unit that can be in­stalled in­side or out­side the home. Though this bat­tery is de­signed for the res­i­den­tial mar­ket there are also ma­jor ben­e­fits for power re­tail­ers and en­ergy dis­trib­u­tors.

Th­ese util­i­ties can re­duce de­mand on their re­sources dur­ing peak times and pro­vide sav­ings to the con­sumer, along with pro­vid­ing backup to run crit­i­cal equip­ment dur­ing a blackout.

En­ergy dis­trib­u­tors can use this as a cost ef­fec­tive al­ter­na­tive to in­creas­ing grid in­fra­struc­ture for scale-abil­ity in meet­ing f luc­tu­at­ing en­ergy de­mands, such as a cold win­ter’s day when all house­holds are run­ning heaters and elec­tric­ity de­mand is too high for the grid.

“In­clud­ing the home stor­age bat­tery sys­tem into new home build­ing costs just makes sense for our fu­ture,” says Fowler.
