2026-06-23
To meet the project’s steady 500 kW load requirement, Ruisu employs a dual-unit parallel operation mode under normal loaded conditions, with both units running in synchrony and sharing the load evenly to deliver a stable 500 kW of power, thereby ensuring the continuous operation of the grouting unit and its associated equipment.

On the “life-or-death line” of infrastructure projects, time is never just money—it is cost, it is safety, and it is the absolute threshold determining the success or failure of the project.
In a time‑critical tunnel project in Shandong, a seemingly simple power‑supply issue once brought the entire operation to a standstill. The project’s core grouting unit required a stable 500 kW of power, with each continuous work cycle lasting 6–7 hours. If the power was interrupted for more than 15 minutes, the underground slurry would solidify instantly, jamming the drill bit and damaging the equipment—resulting not only in direct losses amounting to millions but also causing irreversible delays to the project schedule.
When all conventional power‑supply solutions on site were effectively ruled out by practical constraints, the Ruisu mobile energy‑storage unit provided a viable answer to the project’s power‑supply challenges while ensuring compliance with safety standards.
Triple Deadlock: The Conventional Power Supply Scheme Has Completely Failed Across the Board
The tunnel project is under an extremely tight schedule, and grouting operations—critical to advancing the work—could trigger a cascade of delays if postponed. However, three major on-site power‑supply challenges have compounded one another, leaving even the most conventional solutions in a dead end.
External power supply: Approvals take a long time, and distant water cannot quench immediate thirst.
Initially, the project planned to supply power via a cable routed from the transformer substation on the opposite side—a standard and straightforward approach. However, practical constraints rendered this option unfeasible. Laying the cable would require occupying public roads, necessitating road closures for construction. Obtaining approval for such closures involves coordinating with multiple agencies, including traffic authorities, road administration, and urban management, and completing the entire process can take at least several dozen days.
Diesel Power Generation: Environmental Red Line—Any Violation Triggers a Complete Work Stoppage
As a long-standing mainstay of engineering power supply, the diesel generator has now encountered two major red flags in this project. On the one hand, costs remain stubbornly high: equipment rental, fuel consumption, and labor expenses for operations and maintenance all add up, and prolonged use would significantly drive up the project’s overall cost. On the other hand, there are insurmountable environmental and public‑health constraints.
Zero-tolerance baseline: A 15-minute power outage can result in irreversible losses on the order of millions.
Even more challenging than the difficulty of securing power supply is the project’s nearly exacting requirement for stable electricity delivery. According to on-site measurements, the total load during steady‑state operations reaches 500 kW, representing a typical high‑power, continuous‑use scenario. Moreover, the core construction equipment—the grouting unit—can operate continuously for 6 to 7 hours per shift, and any power interruption is strictly prohibited throughout the entire process, with zero tolerance for failure.
Field‑site data show that if the power supply is interrupted and equipment remains offline for more than 15 minutes, the underground grouting slurry will rapidly solidify, directly jamming the downhole drill bit. This not only results in the complete destruction of equipment worth hundreds of thousands of yuan but also necessitates large‑scale rework, severely delaying the overall project schedule and inflicting irreparable financial losses and reputational damage. Consequently, an uninterrupted, highly stable, and zero‑fluctuation power supply has become an essential, non‑negotiable prerequisite for this project’s construction.
Ruisu Breaks the Impasse: Building an Ironclad Defense for Uninterrupted Power Supply
Faced with the complete failure of conventional solutions, Ruishu Intelligence leveraged its deep expertise in energy storage and extensive experience in engineering power supply to tailor a 1,078 kWh mobile energy‑storage vehicle–based power solution for this project, comprehensively overcoming all power‑supply challenges.
To meet the project’s steady 500 kW load requirement, Ruisu employs two 1,078 kWh mobile energy storage units operating in a parallel‑connected, normally loaded configuration. The two units run in synchrony with balanced load distribution, delivering a stable 500 kW of power and fully satisfying the continuous operational needs of the grouting unit and its associated equipment.
To completely eliminate the risk of power outages, Ruisu has additionally deployed two identical units as load‑bearing backup systems, thereby establishing a “ Primary + Backup + Emergency A triple‑redundancy power supply system. At its core, all equipment supports seamless hot‑swapping, ensuring zero fluctuations and zero interruptions in power delivery—whether during routine unit rotation and maintenance or when switching to backup under sudden failures—truly enabling “power on while swapping.”
This solution perfectly meets the grouting equipment’s requirement for continuous operation over 6–7 hours per shift, fundamentally breaking the “a 15‑minute power outage equals disaster” curse and establishing the project’s most robust power‑supply safeguard.
A Triumph Over Tradition: Green Power Solutions Redefine Engineering Power Supply Standards
Compared with conventional grid‑connected and diesel‑powered solutions, the Ruisu mobile energy storage vehicle system offers unparalleled comprehensive advantages, making it the only optimal solution that simultaneously meets the four critical benchmarks of project timelines, environmental protection, public welfare, and safety.
1. Zero pollution, zero noise—meeting both environmental and public‑health standards.
The energy‑storage vehicle is fully electric, producing zero exhaust emissions and completely eliminating environmental pollution. Its operating noise remains below 75 decibels, ensuring it does not disturb nearby residents and easily meeting all environmental and public‑health regulations.
2. Flexible and agile—ready to use right away, helping you reclaim precious time.
The equipment features an integrated, mobile, vehicle-mounted design that enables quick disassembly and assembly, flexible relocation, and agile deployment—eliminating the need for cumbersome approval processes and complex infrastructure. The project’s plan was finalized on the same day, the equipment was delivered to site the following day, and commissioning and startup were completed within 24 hours, saving the project dozens of precious days.
3. High-power, long-duration power supply with multiple layers of redundancy for foolproof reliability.
A single 1,078 kWh high-capacity energy storage unit can sustain a 500 kW load for more than two hours, while dual units operating in parallel can meet the 6–7 hour continuous operation requirements of grouting equipment. Coupled with redundant backup units, this configuration ensures an unwavering power supply under any unforeseen circumstances.
Fully compatible across all scenarios, meeting diverse power requirements for various engineering applications.
Ruisu’s intelligent mobile energy storage solution can meet the electricity needs of construction projects across the entire project lifecycle and in all operational scenarios.
• Project Pre-Phase: When the municipal power grid is not yet connected, construction power will be provided throughout the entire project.
• Pile foundation construction: Ensure the continuous operation of heavy machinery.
• Linear projects: Field projects such as highways and pipelines can be relocated at any time to keep pace with construction progress.
• Project Department Living Quarters: Meet the round-the-clock electricity demands of office operations, lighting, air conditioning, cafeterias, and other facilities.
• Emergency Backup: In the event of a mains power failure, it serves as a backup power source, ensuring uninterrupted operation of critical loads.
