Working together

An Oklahoma water infrastructure provider needed reliable power to move produced water from oil and gas wells across the state. Because some of its remote locations were not expected to receive permanent utility power, the customer depended on temporary diesel generation to support ongoing water-transfer and saltwater-disposal operations.

The customer was previously powering each of its sites with a dedicated diesel generator. At these sites, the generators operated 24 hours a day, even when power demand was relatively low. Although this approach provided the reliability the oilfield required, the customer needed an engineered energy solution that could maintain uninterrupted power while reducing generator runtime, fuel consumption and associated emissions.

Aggreko engineered a hybrid power solution for two remote oilfield sites. Each package paired a 110 kW Tier 4 Final diesel generator with a 120 kWh battery energy storage system (BESS).

Primary power for the customer’s application was supplied by the battery, while the generator operated only when the BESS needed to recharge. This allowed the sites to maintain dependable 24/7 power without running diesel generators around the clock.

Aggreko Remote Monitoring (ARM) provided visibility into equipment performance, system operation and generator runtime. This gave the customer ongoing insight into each hybrid package and helped demonstrate how battery storage could reliably support remote oilfield operations.

At the converted sites, generator runtime fell from 24 hours a day to approximately three hours each day, a reduction of about 87.5%.

Reducing generator runtime by approximately 21 hours per day significantly lowered fuel consumption, refueling needs, engine wear and maintenance requirements while maintaining uninterrupted power.

By significantly reducing generator runtime and fuel consumption while maintaining dependable energy, the hybrid system delivered measurable operational and financial value and established a reliable, scalable model for additional oilfield sites.
