Case Study: Mobile BESS Reduce Fuel Costs at Data Center Construction Site
Challenge:
A data center construction project in Nevada, supported by United Rentals, turned to POWR2’s POWRBANK mobile battery energy storage systems (BESS) to reduce fuel consumption, lower emissions, and improve overall efficiency for jobsite office power.
Solution:
United Rentals deployed two POWRBANK XPRO 90kVA/120kW/400V mobile battery energy storage systems, paired with a 180kVA diesel generator, to power the office trailer at the data center construction jobsite.
Results:
With two POWRBANK XPRO mobile BESS deployed alongside a diesel generator, the customer was able to cut generator runtime from 24/7 operation to just 3 hours per day for battery recharging.
Over the course of one month, the setup delivered significant operational and financial benefits:
- Generator runtime reduced by 87.5%
- Monthly fuel savings of 3,528 gallons
- Fuel costs cut by over 87%, saving $13,759 in fuel costs alone in just one month
- Service costs reduced by 88%
- Carbon emissions reduced by approximately 88%
- Net savings of $13,013 per month, even after accounting for BESS rental
“Customer feedback has been very positive. We’ve deployed similar setups at two additional data center sites in the area, all with equally successful outcomes. Some of these rentals have been in place for 6–7 months, and our latest is on a 2-year rental term […]
We believe these systems will continue to gain traction, especially on larger, long-term jobsites.”
– Cory Sample, Branch Manager, United Rentals
Conclusion: Mobile BESS for Data Center Construction Projects
Integrating a battery energy storage system helped United Rentals provide a dependable and efficient power solution for their customer’s data center construction project. The customer benefitted from reduced fuel consumption and maintenance costs, demonstrating the real-world advantages of battery energy storage on large-scale jobsites.
