Working together

Construction at a remote Utah gas plant depended on uninterrupted power 24 hours a day, seven days a week. The customer had been relying on generator power to support the site, but the cost of keeping generators running continuously was adding up quickly. High fuel consumption, frequent refueling, ongoing maintenance, and the logistics of supporting equipment at a remote location were driving operating costs higher.

As construction progressed and electrical demand increased, the customer needed a more efficient and scalable approach. The system had to maintain continuous power, respond to fluctuating loads and expand alongside the project without requiring every generator to operate around the clock.

Aggreko engineered a hybrid system combining four Tier 4 Final generators with approximately 1 MW of battery energy storage and temporary electrical distribution.

Each battery energy storage system (BESS) was paired with a primary charging generator and a backup standby unit for extra redundancy. Every generator pair was also linked to a dedicated fuel tank, as well as a diesel exhaust fluid (DEF) tank to support Tier 4 Final operation.

The generators supplied peak demand and recharged the batteries, while the primary power for the site was supplied by the BESS. This allowed the system to maintain uninterrupted 24/7 power without requiring the generators to run continuously.

Aggreko Remote Monitoring (ARM) and Aggreko Connect provided ongoing visibility into equipment performance, generator utilization, and system operation. The modular design also allowed Aggreko to expand the package as construction demands increased.

The hybrid package maintained uninterrupted power around the clock while limiting generator operation to approximately three to four hours per day during the reported period.

Using battery power during lower and variable load periods produced significant fuel savings by eliminating unnecessary generator runtime. The reduced operating hours also lowered refueling requirements and helped limit generator wear and routine service needs without compromising site reliability.

The scalable system provided the dependable power needed to keep construction moving while delivering a more efficient approach than continuous generator operation.
