The Challenge
Temporary power for large event environments must remain reliable while responding to variable loads, changing site needs, and operational pressure to control fuel use. In low-load or intermittent-demand applications, traditional generators can continue consuming fuel and adding engine hours even when power demand is limited.
-
Reduce unnecessary generator runtime during low-load conditions
-
Limit fuel consumption and refueling needs across the event window
-
• Lower emissions without compromising power availability
-
Support operational visibility across multiple deployed units
The Solution
EBOSS® hybrid energy systems were deployed to pair energy storage with generator power, allowing the system to support site loads while reducing the amount of time the generator engine needed to run. This made the application well suited for the NASCAR environment, where average loads stayed low relative to the potential output of traditional generator equipment.
The Results
Across the reporting period, EBOSS® reduced generator runtime by 89.6% and fuel usage by 84.0% compared with the standard generator baseline. The monitored units consumed approximately 260.0 gallons of fuel versus an estimated 1,629.7 gallons from traditional generator operation, saving 1,369.7 gallons and an estimated $8,218.45 at $6.00 per gallon. EBOSS® also reduced CO2 output by approximately 30,751 lbs, or 14.0 metric tons, during the five-day event window.
Why EBOSS®?
-
Reduces engine runtime by allowing the generator to shut down or run less frequently when the battery system can carry the load
-
Improves fuel efficiency in variable or low-load applications where traditional generator operation can be inefficient
-
Supports more informed power management through performance data, telemetry, and measurable operating results.
For this deployment, EBOSS® produced 106.0 engine runtime hours compared with an estimated 1,020.2 hours from the standard generator baseline, avoiding 914.2 engine hours over the reporting window.
Why This Matters?
This application highlights where EBOSS® can create measurable value: temporary power environments with variable loads, tight operating windows, and a need to reduce fuel use without adding complexity in the field. The NASCAR results show that hybrid power can be especially effective when equipment is traditionally oversized for peak demand but spends much of the operating period at lower load levels.
-
Relevant to events, entertainment, construction, telecom, utilities, and rental fleet applications
-
Scalable across multi-unit deployments where fuel, runtime, and emissions savings compound quickly
-
Provides a performance-backed model for customers evaluating hybrid power as part of a more efficient temporary power strategy
Closing
EBOSS® helps teams rethink temporary power by reducing runtime, lowering fuel consumption, and supporting more efficient field operations. For applications where load demand changes throughout the day, ANA can help evaluate where hybrid power makes the most operational and financial sense.
