In the oil and gas exploration and development sector, reliable power supply is a critical enabler for the smooth execution of drilling operations. As the electrification of drilling rigs continues to advance, the characteristics of high‑power load concentration and severe transient fluctuations are increasingly exposing the limitations of conventional power‑supply systems. As a manufacturer with end‑to‑end capabilities across the entire value chain of charging and energy‑storage equipment, Ruisu Intelligent Technology has precisely identified the industry’s key power‑supply challenges and developed a specialized mobile energy‑storage power solution for drilling platforms. By delivering a green, efficient energy‑supply model, this solution addresses longstanding bottlenecks in power provision, providing robust support for the high‑quality development of the oil and gas extraction industry.
Gain insights into industry pain points and pinpoint core needs.
The electrification of oil drilling rigs has been underway for several decades, and electric‑driven rigs have become the industry’s mainstream equipment. However, the high‑power, high‑density electrical loads encountered during drilling operations—particularly the thousands of kilowatts of transient load fluctuations in shale‑oil drilling—place extremely demanding requirements on the power supply system. Current mainstream solutions—such as gas‑fired generation, diesel‑fired generation, and high‑voltage grid supply—each suffer from significant drawbacks: obtaining approval for high‑voltage overhead lines can take up to two months, construction typically exceeds 30 days, and the cost of building a 10‑kV transmission line exceeds RMB 180,000 per kilometer; diesel‑generated electricity costs as much as RMB 2.50 per kWh, while gas‑fired generation still incurs costs of around RMB 1.80 per kWh, and associated‑gas‑fired generation is subject to unstable gas production, making reliable power supply difficult to ensure. Moreover, conventional power‑generation methods produce substantial amounts of carbon dioxide and other pollutants, running counter to the nation’s green development strategy.
Based on actual electricity consumption data, the energy‑consumption requirements of different drill‑rig models follow clear benchmarks: the Model 50 rig averages 325,000 kWh per month, with a peak daily demand of 29,000 kWh; the Model 70 rig averages 401,000 kWh per month, with a peak daily demand of 35,000 kWh. The high energy costs and complex operating conditions urgently call for a green, cost‑effective, and highly flexible power‑supply solution.
Innovative solutions unlock a new paradigm in power supply.
Addressing the industry’s key pain points in power supply, Ruisu Intelligence leverages its manufacturing advantages across the entire value chain, Establish a fully closed-loop mobile energy storage and power supply system integrating charging, energy storage, discharging, and transfer, leveraging its core attributes of flexible deployment, efficient operation, and environmental sustainability to upgrade and iteratively enhance the power supply system of drilling platforms.
This plan deploys three mobile charge‑and‑discharge vehicles, each with a capacity of 4 MWh, operating in a cyclic charge‑swap mode: one vehicle charges in the charging bay and, once fully charged, is transferred to the discharging bay for discharge, alternating with the vehicle already stationed there; the remaining two vehicles charge directly in the discharging bay, thereby ensuring the continuous cycling of charging and discharging operations.
After the initial installation, uninterrupted on-site operation can be ensured simply by transferring the remaining battery modules. The battery modules are easily relocated using a tow tractor, and the recharging process is efficient and fully controllable: each transfer and operational cycle takes no more than one hour, and a two-hour charge restores the batteries to full capacity. With four to five recharging cycles per day, the system can meet the drilling rig’s electricity needs around the clock. Compared with conventional power‑supply solutions, this energy‑storage system keeps the cost per kilowatt-hour below RMB 1.47 (including revenue from potential‑energy recovery) and supports shared, reusable deployment across multiple well sites. A single unit can serve an average of three wells annually, delivering power‑supply efficiency that is three times higher than diesel‑generator systems.
Cutting-edge core technologies lay a solid foundation for safety and efficiency.
Leveraging its end-to-end manufacturing capabilities, Ruisu integrates multiple proprietary core technologies into its solution designs, striking a balance between system security and operational practicality. Its key technological advantages are as follows:
Winch Potential Energy Recovery Technology (Supercapacitor Technology)
By employing a supercapacitor energy storage system, the waste potential energy generated by the up-and-down motion of drill rods during drilling can be converted into electrical energy and stored, achieving an energy‑saving effect of 10% and reducing monthly electricity consumption by 40,100 kWh. At the same time, this system lowers the operation and maintenance costs of braking units and resistors, while also mitigating the heat‑related impacts on the electrical control room. The supercapacitor boasts a fast‑charge/rapid‑discharge capability of one million cycles and can deliver 98% of its stored energy across a full temperature range of –20°C to 45°C. Strong current‑withstand capability , Physical energy storage poses no risk of explosion and exhibits excellent safety performance.
Fully Autonomous 3S System
It encompasses a PCS (power conversion system) optimized for mobile energy storage applications, a standard three‑level architecture BMS (battery management system), and an intelligent EMS (energy management system). The PCS employs a three‑level topology, achieving a peak efficiency of 99% and an IP65 protection rating, enabling derating‑free operation at ambient temperatures up to 45°C. The entire BMS lineup incorporates balancing technology, effectively extending battery life in harsh environments. The EMS supports both local and cloud‑based control modes, with a rich set of built-in application strategies that enable precise energy scheduling.
High-Security Protection System
The battery module employs aerogel insulation technology, achieving an IP67 protection rating and passing UL 9540A certification. It is equipped with a pack‑level automatic fire suppression system using perfluorohexanone, coupled with multi‑dimensional detection sensors for H₂, CO, temperature, and smoke, enabling clustered, directional spray and secondary re‑ignition suppression. The liquid‑cooling system integrates intelligently with the BMS to enable precise temperature control, effectively mitigating thermal runaway risks, with a fire‑resistance duration exceeding two hours.
Backed by the strength of the entire industry chain, we are jointly building a new ecosystem for the energy transition.
Driving industry transformation through technological innovation and empowering energy development with green solutions, Ruisu’s mobile energy storage system for drilling rigs effectively addresses the challenges of conventional power‑supply models—such as cost, environmental impact, and reliability—while showcasing the robust capabilities of a full‑chain manufacturer. Looking ahead, Ruisu will continue to deepen its expertise in the energy‑storage sector, striving to deliver smarter, more efficient, and greener power‑supply solutions for the oil and gas exploration industry, and working hand in hand with industry partners to usher in a new chapter of sustainable energy development.
