In the fast-paced environment of the Permian Basin, water transfer operations depend on steady, reliable power to keep product moving through the pipeline. Aggreko initially designed and installed a dual-generator solution for the customers, two natural gas units, which provided redundancy and dependable energy for nearly a year.

The configuration was effective, meeting operational needs and maintaining uptime across demanding field conditions. However, as energy storage technology evolved, Aggreko identified a new opportunity: to enhance the system’s efficiency, reduce emissions, and streamline operation, without compromising reliability.

Through continuous monitoring and collaboration with the customer, Aggreko recognized this site as an ideal candidate for a hybrid power upgrade. This project would become the company’s first-ever natural gas and battery energy storage application, marking a new milestone in innovation for temporary power systems in oil and gas.

Aggreko implemented a 350 kW natural gas generator integrated with a 500 kW / 250 kWh battery energy storage system (BESS), a first-of-its-kind configuration within the company and the sector.

In this design, the generator charges the battery, and the battery powers the site’s 30-amp metering station and pump operations. The generator operates automatically twice per day for about one hour, maintaining ideal load levels and extending its service life. During all other hours, the battery delivers smooth, continuous power, eliminating unnecessary runtime and minimizing fuel consumption. This hybrid approach reduced generator runtime and fuel costs by approximately 96%.

If for any reason the battery’s charge drops or the system requires additional load support, the generator automatically takes over, ensuring uninterrupted power delivery. This hybridized design not only sustains performance but also introduces a subtle boost in reliability, combining stored energy with proven natural gas generation for round-the-clock dependability.

By operating fully on propane, the system can deliver approximately 50% total emission reductions versus using a traditional diesel unit. Because the generator runs for only a few hours each day, the customer also benefits from lower air permitting requirements, fewer maintenance intervals, and extended equipment lifespan.

The entire system is integrated with Aggreko Remote Monitoring (ARM), providing 24/7 visibility into equipment performance. Through ARM, Aggreko’s operations team can track system health, monitor pipeline pressure, and send remote start signals when product movement is required. This level of oversight ensures proactive issue detection, faster response times, and maximum uptime, all key contributors to the site’s enhanced reliability.

The hybrid system has proven to be a powerful evolution of the original setup, delivering measurable improvements in performance, sustainability, and operational efficiency.

By transitioning from a dual-generator design to a generator-plus-battery configuration, the customer maintained the same dependable power supply while achieving:

• 96% reduction in generator runtime and 96% savings in fuel costs, achieved by shifting from a dual-generator setup to a hybrid generator-and-battery system
• Reduced air permitting costs, thanks to limited generator runtime
• Enhanced reliability, through battery backup, automatic transfer, and continuous monitoring
• Fuel savings, with propane operation and fewer generator hours
• Greater operational insight, enabled by 24/7 remote monitoring

This project not only met the site’s demanding power needs but also set a precedent for innovation within Aggreko and the oil and gas industry at large.

As the company’s first natural gas and battery hybrid deployment, it demonstrates how Aggreko continues to push boundaries, blending proven generation technology with modern energy storage to deliver cleaner, smarter, and more reliable power for critical field operations.
