Dewatering is a critical part of keeping mine sites safe, productive, and operational. Traditionally powered by diesel generators, these systems often run inefficiently, burning excess fuel and requiring frequent maintenance. Hybrid generators are changing that.
By combining diesel power with battery energy, hybrid generators offer a more efficient, reliable, and environmentally friendly way to keep water moving. In this article, we explore the key benefits of hybrid generators in mine dewatering and why more operations are making the switch.
One of the most immediate benefits of hybrid generators is the reduction in carbon emissions. By running the diesel engine only when necessary, hybrid systems consume significantly less fuel than traditional generators. This not only lowers CO₂ output but also reduces the release of other harmful pollutants such as NOx and particulate matter.
For mining operations with ESG commitments or compliance targets, hybrid generators provide a practical way to cut emissions, reduce environmental impact, and demonstrate sustainable practices—all without compromising performance.
Hybrid systems are designed to adapt to variable loads in real time. Instead of relying solely on a diesel engine running at constant speed, hybrid generators use a combination of diesel and battery power to match actual demand. When the Battery Energy Storage System reaches its healthy state of charge, it can fully power the dewatering pump while the generator stays in an idle state.
Additionally, generators are often oversized to handle peak loads or to account for high load starting. The result is long stretches of inefficient operation. During low load periods, the diesel generator prime movers experience the phenomenon known as glazing, which reduces the life of the system and causes more maintenance issues.
Hybrid generators offer a perfectly suited solution to this problem by ensuring that the generator is always running at optimal capacity. They also ensure that any unused energy is stored in the Battery Energy Storage System until it’s to power the dewatering pump by itself. The result is a smoother, more efficient operation that delivers power when and where it’s needed.
Because hybrid systems combine battery storage with traditional diesel engines, the generator doesn’t need to run continuously. This directly translates to longer intervals between servicing, less frequent oil and filter changes, and reduced wear on critical components like injectors, belts, and cooling systems.
Moreover, hybrid generators avoid the problems caused by light loading. This is when diesel engines run for extended periods at low capacity, leading to issues like glazing. Hybrid systems eliminate the problem by ensuring the generator is always running within optimal operating conditions. The result is better engine health over the long term.
First and foremost, hybrid systems significantly reduce diesel consumption. By intelligently sharing the load between battery storage and the diesel engine, fuel is only used when necessary. This lower fuel usage also reduces the site’s dependence on diesel deliveries, which is an expensive and logistically complex task in remote mining regions.
Maintenance costs are also reduced. With fewer running hours on the diesel engine, there’s less wear and tear, fewer component failures, and longer gaps between servicing. Hybrid systems often allow for extended service intervals, which cuts down on labour, parts, and downtime.
Our GENVAR-BLUE™ hybrid generators are fully compatible with automated pump controls and telemetry platforms commonly used on mine sites. This allows the generator to respond dynamically to changing site conditions, such as automatically starting or stopping based on water levels, pump demand, or time schedules. It also enables real-time optimisation of performance, fuel usage, and battery cycling without the need for constant operator input.
Allied Pumps’ hybrid generators can also be paired with our proprietary NODEM remote monitoring system. NODEM provides 24/7 access to performance data, system status, fuel levels, and fault alerts, all from a central dashboard. The system supports predictive maintenance features by tracking usage patterns, identifying trends, and alerting maintenance teams before a failure occurs. This helps prevent unplanned downtime and extend equipment life.
The GENVAR-BLUE™ hybrid generator is Allied Pumps’ next-generation solution for efficient and low-emission dewatering on mine sites. At the heart of the GENVAR-BLUE™ is a Battery Energy Storage System (BESS) integrated with a solar panel to generate and store clean energy. This setup reduces reliance on diesel, cuts fuel consumption, and dramatically lowers carbon emissions.
Our GENVAR-BLUE™ can also be trailer mounted, making transport and relocation across rugged terrain simple and efficient. Whether you’re moving between pits or shifting dewatering locations, the generator can be repositioned quickly with minimal setup time.
With a power output range of 60–300 kVA and a nominal voltage of up to 690V, the GENVAR-BLUE™ can be fitted with pump headworks to create a fully integrated dewatering solution. Don’t hesitate to contact us to learn more about the benefits of our hybrid generators and dewatering trailers.
