In oilfield drilling operations, “unstable power supply,” “power outages causing work stoppages,” and “soaring costs” have long been the three major challenges plaguing the field—deep‑well drilling equipment can consume more than 20,000 kWh of electricity per day, while conventional power‑supply solutions are either constrained by grid coverage or face skyrocketing fuel‑generated electricity costs. Today, Ruisu Intelligent’s “2 MW/4 MWh Mobile Energy Storage and Charging System” offers a breakthrough solution: three units operate in a cyclical manner, ensuring that drilling equipment can run at full load. It can also generate an annual profit of 6.93 million, with a rapid payback period of just 1.75 years, making it a new option for green power supply in oilfields.
Why do oilfield drilling operations require mobile storage and refueling systems? Three major pain points addressed in one go.
The unique characteristics of oilfield drilling operations have long posed a dilemma in power supply planning: either rely on a distant grid, which can lead to immediate shutdowns in the event of line failures, or use diesel generators—resulting in electricity costs exceeding RMB 1.8 per kilowatt-hour and facing stringent environmental emission regulations. The introduction of Ruishu’s intelligent mobile energy storage and charging system precisely addresses the core needs of oilfield environments:
Addressing the “power supply gap” issue
• Employing a “two discharging units plus one charging unit” cycling mode, each energy‑storage vehicle has a capacity of 4 MWh (4,000 kWh). Three units rotate in a seamless energy‑replenishment cycle, supported by an efficient battery‑swap process that takes 0.5 hours for transfer and another 0.5 hour for operation, ensuring 24‑hour uninterrupted power supply. The average daily discharge reaches a steady 21,000 kWh, fully meeting the daily electricity demand of a large oil‑drilling platform.
Reduce the pressure of “electricity costs”
• The charging end can be connected to a photovoltaic power plant, a wind farm, or the grid, with a combined charging cost of just RMB 0.6 per kWh. At the discharge end, using the oilfield’s standard tariff of RMB 1.6 per kWh, each kilowatt-hour yields a net profit of RMB 1. Over a year, assuming 330 operating days, the pure discharge‑side profit amounts to RMB 6.93 million—significantly lower than the cost of diesel‑generated power.
Compatible with “Mobile Work” scenarios
• The entire system is housed in a 20-foot container (dimensions: 6,058 × 2,438 × 2,896 mm) and can be easily transported to various drilling platforms when coupled with a tractor unit and trailer. The battery compartment features an integrated liquid‑cooling thermal management system and a perfluorohexanone fire‑suppression system, ensuring stable operation across an ambient temperature range of −30°C to 50°C and accommodating the complex field conditions typical of oilfield environments.
Deconstructing the system core: From hardware to workflows, every step is engineered for “stable power supply.”
Enabling 24-hour continuous operation hinges on Ruishu Intelligence’s meticulous system design—spanning everything from battery selection to charge‑discharge logic, with the entire solution engineered around “high reliability” and “high cost‑effectiveness.”
beginning Initial deployment
Discharge platform: Install two discharge chambers, connect battery chambers No. 1 and No. 2 to their respective PCS (power conversion systems), and, once started, supply power to the drilling equipment; battery chamber No. 3 is connected to… #PCS Connected, in standby mode.
Automatic switching
When the charge level of battery compartment #1 falls below the threshold, 3 #PCS Immediately connect to the grid, with the three PCS units sharing the load equally until Unit 1’s battery module is fully discharged, at which point the system shuts down and the load automatically transfers to Units 2 and 3.
Transfer charging
The removed No. 1 battery module is transported to the charging bay via trailer (transit and handling take only one hour), and once connected to a photovoltaic system or grid power, it can be fully charged in two hours.
Cyclic substitution
The fully charged battery module No. 1 is transferred back to the discharge platform, awaiting replacement by the next low‑state‑of‑charge module, thereby enabling a continuous “one charging, two discharging” cycle.
Under this operating mode, the system can deliver an average of 21,000 kWh per day, fully meeting the baseline power demand of large oil drilling platforms (which typically consume 20,000–120,000 kWh daily) and reliably handling peak load conditions.
A clear economic analysis: payback in 1.75 years—even oilfield power supply can “make a profit.”
For oilfield customers, “ease of use” is only part of the equation—“cost-effectiveness” matters even more. Taking the initial investment and operational returns of the Ruishu Intelligent Mobile Charging and Storage System as an example, let’s lay out a clear, transparent economic analysis:
Initial investment: Total outlay approximately RMB 12.18 million, with hardware and vehicles procured in a single phase.
Operating income: annual profit of 6.93 million, with a payback period of just 1.75 years.
• Core Earnings Discharge price: 1.6 yuan/kWh – Charging cost: 0.6 yuan/kWh = Net profit per kWh: 1 yuan
• Average daily profit : 21,000 degrees × 1 yuan/degree = 21,000 yuan
• Annual profit : 21,000 yuan × 330 days (annual operating days) = 6,930,000 yuan (6.93 million)
• Payback period : 12.15 million ÷ 6.93 million/year ≈ 1.75 years
Compared with conventional diesel‑powered generation, which costs RMB 1.8–2.2 per kWh, this system not only reduces electricity expenses but also generates profits through the price differential. Over the long term, it aligns with the national “dual carbon” policy and supports the oilfield’s transition to a greener operation.
Oilfield power supply enters the “mobile energy storage era”
As oilfield drilling advances toward greater depths and increased environmental sustainability, traditional power‑supply solutions can no longer meet evolving demands. Ruisu Intelligent’s 2 MW/4 MWh mobile energy storage and charging system offers three key advantages—“24‑hour continuous power supply,” “a payback period of 1.75 years,” and “flexible adaptation to field operating conditions”—providing oilfields with a groundbreaking new power‑supply option.
If your oilfield is grappling with unreliable power supply and soaring costs, consider this mobile energy storage and charging system—it ensures uninterrupted drilling operations, delivers tangible economic benefits, and supports a green transition.
