The Challenge
Temporary wastewater treatment sites are often deployed in tight, fast-moving environments where utilities infrastructure is limited,ted and consistent power is essential to keep treatment operations running smoothly. In this case, the power system supported a temporary site that included catering and support tent infrastructure, along with the equipment required to maintain treatment continuity.
Because treatment systems cycle based on water conditions, filtration stages, and operational needs, the site experienced highly variable load demand. These fluctuations can make diesel-only generation inefficient, increasing fuel consumption, runtime, and maintenance while producing unnecessary noise and emissions.
For this project, MTD needed stable power delivery for a 480V / 277V system, while reducing fuel consumption and minimizing operational impact.
The Solution
ANA supplied its EBOSS 70-45 hybrid power solution, with Aggreko serving as the dealer partner responsible for deployment and integration. EBOSS combines traditional generation with battery energy storage, allowing the system to respond dynamically to changing load conditions.
The hybrid configuration enabled:
- Smooth handling of rapid load changes
- Stable voltage and frequency for critical treatment operations
- Reduced generator runtime by shifting peak demand support to stored energy
- Significantly improved efficiency compared to diesel-only generation
The compact footprint of the EBOSS unit also proved critical, allowing the system to fit within the site’s tight spatial constraints without sacrificing performance.
Performance Profile
- Peak load: ~220 kW
- Average load: ~80–120 kW
- Operating environment: highly variable, cycling demand
"The compact footprint of the ANA unit was especially important given the tight space constraints on site. It was rewarding to work side by side with ANA to help ensure the system functioned in a more sustainable way." -
Don Gray, Events Sector Leader - Aggreko
The Results
The ANA EBOSS hybrid system, delivered in close collaboration with Aggreko, produced measurable gains across fuel efficiency, runtime reduction, maintenance requirements, emissions reduction, and power quality.
- Fuel consumption dropped from a modeled 1,389 gallons to 139 gallons - saving 1,250 gallons and more than $7,500 in fuel costs.
- Engine runtime decreased from a modeled 604 hours to just 48 hours, a 92% reduction that helped extend equipment life.
- No oil changes were required, as runtime remained well below the 500-hour service interval.
- The system eliminated 28,071 pounds of CO₂ emissions, comparable to removing multiple passenger vehicles from the road over the same period.
- Power quality improved significantly, supporting pumps, controls, and instrumentation without the low-load instability common in diesel-only systems.
Why This Matters
This project illustrates the power of partnership. By aligning ANA’s hybrid technology with Aggreko’s field expertise, the team delivered a solution that met the realities of temporary wastewater treatment—highly variable loads, limited space, and the need for continuous, reliable operation.
For wastewater treatment applications where uptime and power quality are non-negotiable, hybrid power offers a practical path to improved efficiency, lower emissions, and reduced operational strain, without compromising performance.
Conclusion
ANA’s EBOSS hybrid power solution, delivered in collaboration with Aggreko, provided MTD with stable, high-performance power for temporary wastewater treatment operations. The system handled fluctuating load demands with ease while significantly reducing fuel consumption, generator runtime, and environmental impact—demonstrating how hybrid power and strong partnerships can redefine what’s possible in temporary infrastructure.
