Emissions Reduction Calculator

Understanding the emissions reductions and fuel cost savings of utilizing a BESS in Hybrid Mode is a critical part of the energy transition. While exact figures vary by use case, in general terms, generator runtime savings can be up to 80%, and fuel savings can be up to 50% in Hybrid Mode compared to the Generator-Only scenario. The reduction in CO2 emissions directly corresponds to the reduction in fuel consumption. 

To estimate CO2 emissions reductions, the amount of fuel saved in Hybrid Mode is multiplied by the appropriate coefficient for the given fuel type, as found on the EIA Carbon Dioxide Emissions Coefficients list. As shown on the list, each gallon of diesel fuel consumed produces 22.5 pounds of CO2.  A 56-kW generator consumes 3.5 gallons of fuel per hour at 75% load. Operating over a 4-hour period, this generator produces 315 pounds of CO2. Switching to Hybrid Mode and reducing the fuel consumption by 50% saves 157.5 pounds of CO2 from being emitted.
