Highjoule(HJ Group) Secures Contract for Centralised Procurement of Microgrid Equipment at Engineering Group Headquarters

Recently, Highjoule(HJ Group) emerged victorious amidst fierce market competition, successfully securing the contract for the centralised procurement of microgrid-related equipment at a prominent engineering group’s headquarters. This tender outcome has been formally published on relevant procurement platforms, signifying renewed high recognition from clients for the company’s comprehensive capabilities in new energy microgrids and integrated photovoltaic-storage solutions.

I. Usuli wa Mradi: Kuhudumia Usalama wa Nishati katika Mikoa ya Plateau, Kusaidia Maendeleo ya Kijani na Kaboni ya Chini

Kwa maendeleo endelevu ya mkakati wa kitaifa wa 'kaboni mbili' na maendeleo ya kasi ya mifumo mipya ya nishati na nguvu mpya, mifumo ya gridi ndogo inazidi kuonyesha jukumu lake muhimu katika kuhakikisha usalama wa nishati katika maeneo ya mbali na mazingira magumu. Ikiwa karibu na Tibet kwa urefu wa takriban mita 4,500, eneo hili la mradi linaonyesha mazingira ya kawaida ya mwinuko wa juu, baridi, oksijeni kidogo, na mionzi ya juu ya violet. Hii inaleta mahitaji makubwa sana kuhusu uaminifu, unyumbulifu, na ufanisi wa uwekaji wa vifaa vya umeme.

Mradi uliotolewa unashughulikia kimsingi mahitaji ya uhandisi na usambazaji wa umeme wa viwandani katika maeneo ya nyanda za juu. Unatumia suluhisho la gridi ndogo ya kuhifadhi nishati ya photovoltaic iliyojumuishwa inayochanganya vyombo vya PV vinavyoweza kukunjwa na makabati ya kuhifadhi nishati. Kwa kuratibu uzalishaji mbadala na kanuni za uhifadhi wa nishati, mfumo huo unaboresha kwa kiasi kikubwa ufanisi wa matumizi ya nishati huku ukipunguza utegemezi wa mafuta ya asili ya visukuku, na hivyo kutoa usaidizi thabiti kwa usambazaji endelevu na thabiti wa nishati katika maeneo ya nyanda za juu.

II. Muhimu wa Suluhisho la Mradi: PV inayoweza kukunjwa + Hifadhi ya Nishati, Imeundwa Maalum kwa Ajili ya Urefu wa Juu - Usakinishaji Rahisi, Upana Unaonyumbulika, Uendeshaji Uthabiti

Addressing extreme conditions at 4,500 metres altitude—including low atmospheric pressure, sub-zero temperatures (winter lows reaching -30°C), intense solar radiation, and significant diurnal temperature fluctuations—Highjoule(HJ Group) conducted specialised high-altitude environmental verification and system derating during the design phase. This ensures core equipment maintains efficient heat dissipation and stable operation in thin air conditions.

• Hutumia vyombo vya moduli na vinavyoweza kupanuka vya photovoltaic vinavyokunjwa. Wakati wa usafirishaji, ujazo wake hubanwa hadi theluthi moja ya mifumo ya kawaida, na hivyo kupunguza kwa kiasi kikubwa changamoto za vifaa vya urefu mrefu. Ufungaji wa ndani ya jengo unahitaji tu kuinua, kufungua, na kuunganisha nyaya; katika hali ya kawaida, mfumo mmoja unaweza kutumwa na wafanyakazi wawili ndani ya saa nne.
• Ili kuzoea mazingira ya uwanda wa juu, mfumo wa kuhifadhi nishati hutumia betri za fosfeti ya chuma ya lithiamu zenye viwango vya joto pana, zinazokamilishwa na mikakati ya usimamizi wa joto yenye akili. Hii huwezesha kuchaji na kutoa chaji ya kawaida ndani ya kiwango cha joto cha -30°C hadi +55°
• Muundo wa mfumo hutumia violesura sanifu na usanifu wa moduli. Upanuzi wa siku zijazo ili kukidhi mahitaji yaliyoongezeka ya umeme unaweza kupatikana kwa urahisi kwa kuongeza vitengo vya fotovoltaiki au makabati ya kuhifadhi nishati bila kurekebisha mfumo uliopo, na kuwezesha upanuzi wa uwezo wa 'kuziba na kucheza' bila juhudi nyingi.

III. Kushinda Changamoto za Uwasilishaji wa Milima ya Juu Kupitia Utaalamu wa Kitaalamu

Mradi huu ulikabiliwa na changamoto kuu tatu:

• Mazingira ya mwinuko wa juu hulazimisha mahitaji magumu juu ya uaminifu wa vifaa: msongamano mdogo wa hewa hupunguza ufanisi wa utengano wa joto, na kusababisha ulinzi wa joto au kuzima kwa vipengele vya kielektroniki vya umeme;
• Hali ya usafiri na usakinishaji huwasilisha ugumu mkubwa: vifaa vikubwa vya mradi na umbali mrefu wa usafiri huweka mahitaji makali juu ya uadilifu wa kimuundo wa vyombo vya volti vya mwanga vinavyoweza kukunjwa, ulinzi wa usafiri, na usahihi wakati wa kupelekwa na kusakinishwa ndani ya eneo husika;
• Ratiba finyu na dirisha fupi la uwasilishaji: Mradi ulihitaji kukamilika ndani ya muda uliobanwa, na hivyo kuhitaji usimamizi ulioratibiwa wa uzalishaji wa vifaa, vifaa, usakinishaji wa ndani ya eneo husika, na uagizaji wa mfumo - kujaribu uwezo kamili wa usimamizi wa mradi wa kampuni.

In response, Highjoule(HJ Group) proactively implemented high-altitude simulation testing, reinforced structural transport solutions, and pre-integration commissioning. A dedicated high-altitude technical service team was deployed to achieve ‘delivery in one go, success in one attempt’.

IV. Client Recognition: Validation of Highjoule(HJ Group)’s Comprehensive Capabilities

During this competitive negotiation process, Highjoule(HJ Group) distinguished itself through:

• Suluhisho za gridi ndogo za kuhifadhi fotovoltaiki zilizokomaa na za kuaminika
• Uzoefu mkubwa katika kutekeleza miradi mipya ya kuhifadhi nishati na nishati
• Udhibiti kamili wa ubora na mifumo ya huduma baada ya mauzo
• Utaalamu wa kina wa kiufundi katika hali za matumizi ya oksijeni ya chini na ya mwinuko wa juu

Ultimately distinguishing itself among multiple suppliers, Highjoule(HJ Group) secured the recommended shortlist and won the bid. This outcome fully reflects the client’s high recognition of the Group’s technical prowess, product reliability, and project delivery capabilities.
