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. Project Background: Serving Energy Security in Plateau Regions, Supporting Green and Low-Carbon Development

With the continuous advancement of the national ‘dual carbon’ strategy and the accelerated development of new energy and novel power systems, microgrid systems are increasingly demonstrating their vital role in ensuring energy security in remote areas and complex environments. Located in the vicinity of Tibet at an altitude of approximately 4,500 metres, this project site presents a typical high-altitude, cold, low-oxygen, and high-ultraviolet radiation environment. This poses exceptionally high demands on the reliability, adaptability, and deployment efficiency of electrical equipment.

The awarded project primarily addresses engineering and industrial power supply needs in plateau regions. It employs an integrated photovoltaic-storage microgrid solution combining foldable PV containers with energy storage cabinets. By coordinating renewable generation with energy storage regulation, the system significantly enhances energy utilisation efficiency while reducing reliance on traditional fossil fuels, thereby providing robust support for sustainable and stable energy supply in plateau areas.

II. Project Solution Highlights: Foldable PV + Energy Storage, Specially Designed for High Altitude – Convenient Installation, Flexible Scaling, Stable Operation

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.

• Deploys modular, expandable folding photovoltaic containers. During transport, its volume is compressed to one-third that of conventional systems, significantly reducing the challenges of long-distance high-altitude logistics. On-site installation requires only hoisting, unfolding, and wiring; under normal circumstances, a single system can be deployed by two personnel within four hours.
• To deeply adapt to the plateau environment, the energy storage system employs wide-temperature-range lithium iron phosphate batteries, complemented by intelligent thermal management strategies. This enables normal charging and discharging within the temperature range of -30°C to +55°
• The system design employs standardised interfaces and a modular architecture. Future expansion to accommodate increased electricity demand can be achieved flexibly by adding photovoltaic units or energy storage cabinets without modifying the existing system, enabling effortless ‘plug-and-play’ capacity expansion.

III. Overcoming High-Altitude Delivery Challenges Through Professional Expertise

This project confronted three core challenges:

• High-altitude environments impose stringent demands on equipment reliability: reduced air density diminishes heat dissipation efficiency, potentially triggering thermal protection or shutdowns in power electronic components;
• Transport and installation conditions present extreme complexity: the project’s large-scale equipment and extended transport distances impose rigorous requirements on the structural integrity of foldable photovoltaic containers, transport protection, and precision during on-site deployment and installation;
• Tight schedule and short delivery window: The project required completion within a compressed timeline, necessitating coordinated management of equipment production, logistics, on-site installation, and system commissioning – testing the company’s comprehensive project management capabilities.

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:

• Mature and reliable integrated photovoltaic-storage microgrid solutions
• Extensive experience in implementing new energy and energy storage projects
• Comprehensive quality control and after-sales service systems
• Deep technical expertise in high-altitude, low-oxygen application scenarios

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.

V. Continued Dedication to the Photovoltaic-Storage Microgrid Sector

This successful bid represents not only a significant breakthrough for Highjoule(HJ Group) in the high-altitude renewable energy microgrid sector but also another achievement in the Group’s sustained focus on photovoltaic, energy storage, and system integration operations. Moving forward, the Group will leverage this project to further accumulate experience in high-altitude and complex environmental projects, continuously optimise products and solutions, and persistently deliver safer, more efficient, and more reliable new energy system services to clients.

Highjoule(HJ Group) will strictly adhere to project requirements, advance implementation to high standards, ensure equipment quality and delivery schedules, and create a high-calibre microgrid demonstration project for the client. This endeavour contributes to China’s new energy and green infrastructure development.
