Proving Real-World Performance of Hybrid Generators
Field-Tested with DPR Construction
Introduction
Rental companies and contractors alike are looking for cleaner, more efficient, and more versatile ways to power their jobsites. To evaluate how hybrid generator systems perform under real jobsite conditions, ANA partnered with DPR Construction, one of the nation’s leading general contractors, for a year-long field test.
The results show that the EBOSS® 25-25 Hybrid Energy System offers clear and measurable benefits in fuel savings, emissions reduction, and operational uptime, making it a strong fit for both rental applications and long-duration construction deployments.
Field Test Overview
Comparing Three Temporary Power Systems on a Live DPR Jobsite
The pilot was conducted at a 24/7 guard shack on an active DPR jobsite in the Southwestern U.S. Over the course of a year, three different power systems were deployed, monitored, and evaluated:
- A 20 kW diesel generator paired with a 30 kVA / 90 kWh battery energy storage system (BESS)
- A 60 kVA hybrid unit with a 75 kWh Lithium Iron Phosphate battery
- ANA’s EBOSS® 25-25 Hybrid Generator, which combines a 20 kVA engine and a 15 kWh Lithium Titanium Oxide (LTO) battery
Performance was measured across key metrics: runtime, fuel consumption, carbon output, and system complexity.
Performance Results
EBOSS® Outperformed in Fuel Efficiency, Emissions, and Uptime
| Metric | Diesel Gen + BESS | Competitive Hybrid | ANA EBOSS® Hybrid |
|---|---|---|---|
| Generator Run Time Reduction | 81% | 78% | 91% |
| Fuel Burn Reduction | 65% | 14% | 83% |
| Estimated CO₂ Avoided (MT) | 246.81 | 155.79 | 314.73 |
| Yearly Cost Savings | N/A | N/A | $15,000 |
| Oil Changes Saved | N/A | N/A | 15 |
EBOSS® delivered the strongest performance in every category. Emissions reduction from the EBOSS® unit is equivalent to taking 11 cars off the road or powering 5 homes for a year.
What Makes EBOSS® a Smart Hybrid Power Choice
Key Features of the EBOSS® Hybrid Generator
Several design and engineering advantages contributed to the EBOSS® system’s performance:
- Single-trailer configuration reduced delivery and setup time
- Fast-charging LTO battery (under 45 minutes) kept downtime to a minimum
- Remote monitoring capabilities supported proactive service and planning
- Compact, lightweight footprint improved mobility and fleet flexibility
In contrast, the other systems required more space, more setup, and longer charging times — limiting their rental and jobsite versatility, required more setup time, used more fuel, or involved bulkier equipment. The diesel + BESS option required separate trailers and hookups, while the 60 kVA hybrid had a heavier footprint and longer battery charge time.
Industry Collaboration and Insights
Field-Tested by DPR for Real-World Validation
Partnering with DPR Construction allowed ANA to validate hybrid system performance under continuous jobsite demands. The EBOSS® system alone helped avoid over 15,000 engine hours, contributing to a total CO₂ emissions reduction of 70% across all systems tested.
“We saw benefits from all of the solutions piloted. In our experience, the most favorable solution appears to be the ANA EBOSS®,” shared one project leader at DPR.
Conclusion
A Proven Hybrid Power Solution for Rental and Construction Markets
With a track record of fuel efficiency, lower emissions, and simplified deployment, the EBOSS® 25-25 Hybrid Generator stands out as a dependable solution for rental companies and contractors working toward sustainability goals without sacrificing performance.
