1 Totally Electrifying - 3 Years of Experience Keith Moody Clemson Area Transit (CATbus) Interim General Manager Clemson, South Carolina

2 Everyone Rides Free Clemson Area Transit Founded: January 9, 1996 Service Area: The western half of the Greenville UZA that includes Clemson and Clemson University with service to Seneca, Central, Southern Wesleyan University, Pendleton, Tri-County Technical College, Anderson, and Anderson University

3 Seneca, South Carolina Population: 8,201 Oconee County: 75,045 Bus Service Started: October, 2006 TIGGER III funding grant applied for: 2010 All Electric Service Started: September, 2014 Seneca partnered with CATbus, the Center for Transportation and Environment (CTE), and SCDOT to apply for TIGGER III funding to develop the first scalable model of an all-electric bus transit system in the U.S.A.

4 Clemson Area Transit, CTE and Seneca developed a deployment methodology that included Planning, Route Modeling, Route Validation, Shadow Testing, Deployment, and Benefits Realization [Deployment Validation and Analysis]

5 Secondary Charger The design planning of the Seneca model was for all-electric service for the entire operation. To achieve this the use of two chargers on separate grids was planned so there would be power to charge even if one of the chargers lost power. The second charger [at the left] is located at the hospital that has backup power. So in the event of a disaster, power would be available for evacuation. Primary Charger Clemson Area Transit noted that Seneca was one of a few bus systems in the country with routes that were 100% compatible with the range of electric buses at that time.

6 Comparisons with CAT s Diesel Fleet Miles per Gallon equivalent: Diesel = 3.8 MPG Electric = MPGe Fuel Cost per Mile, Monthly Average: Diesel = $0.58 Electric = $0.28 Maintenance Cost per Mile: Diesel = $1.53 Electric = $0.55

The variation comes from the number of service days in each month. We have 0 diesel miles since deployment.

14 Keys to the Success of the All-Electric Model 1. Ensure adequate funding for the start of the conversion to electric service 2. Get information from agency's that are using the technology [Doran Barns invited us to Foothill Transit] 3. Determine the electric rate structure & use rate modeling in your planning. Start working on officials to enact a transportation rate 4. Study the route modeling data to determine the type of bus for the route, i.e. Quick Charge or Extended Range buses a) Round trip mileage of the route b) Daily total mileage c) Topography d) Route schedule, timing e) Possible location of charging stations 5. Shadow the diesel buses with different vendor s vehicles to see if the model works before going out for bid 6. Make the bid include the needs that have come out of the route study

15 Future Plans for Deployment 1. Clemson Area Transit has recieved additional NOLO funding to use all electric buses on the streets of Clemson and Central, South Carolina, adding to the Seneca model. 2. Seneca has also recieved additional funding to expand its service to more of Oconee County.
