Introduction
Project GoalsAchieve performance levels that meet or exceed existing fleetReduce fuel costsReduce emissionsEnhance transit service Cleaner, GreenerPurpose of KPI Reporting
Assess performance of electric buses as compared to existing fleet
Assess impact on WRTA’s agency-wide fuel costs
Assess impact on WRTA’s agency wide GHG emissionsSlide3

KPI: Mileage Slide6
KPI: Diesel Gallon EquivalentSlide7
KPI: Average Fuel EfficiencySlide8
KPI: Average Fuel Efficiency
Blue months indicate electric bills with estimated reads; kWh consumption was adjusted retroactivelyRed months indicate months with variable supply costs inadvertently left off, making cost/mile less than expectedSlide9
KPI: Fleet Average Fuel Cost per Mile
Contracted Diesel Fuel Cost: $3.14/galAverage Electricity Costs: $0.20/kWhSlide10
KPI: Fleet Average Fuel Cost Per Mile
Blue months indicate electric bills with estimated reads; kWh consumption was adjusted retroactivelyRed months indicate months with variable supply costs inadvertently left off, making cost/mile less than expectedSlide11
Electricity Costs
Blue months indicate electric bills with estimated reads; kWh consumption was adjusted retroactivelyRed months indicate months with variable supply costs inadvertently left off, making cost/mile less than expectedOrange indicates month with lower than typical demand charges applied ($3.26536 vs. $2.92 per kW)
Note: Previous May 14 data included an estimated supply cost charge but was later removed b/c never applied in billSlide12
KPI: Average Fuel Cost per Mile by Type
Contracted Diesel Fuel Cost: $3.14/galAverage Electricity Costs: $0.20/kWhSlide13
KPI: Change in Fleet Average Cost/Mile
Note: Electric buses represent 12% of WRTA total fleetSlide14
KPI: AvailabilitySlide15
KPI: Emission Reduction
Total CO2 Reduction to Date: 305 Tons!
Total Diesel Reduction to Date:
27,000 gallons!Slide16

Conclusions
Greater utilization and the G-3 utility rate switch has lowered the electric cost per mile to below all other buses in WRTA fleets for April – OctoberAvailability issues continue to limit the potential of the electric bus fleetCost per mile is seasonalExpect higher cost/mile in the winter months
