1. Deploying Electric Buses at CTA ICC Electric Vehicle Policy Session 2 Tuesday, September 18, 2018 1

2. Fun facts on CTAs bus system Fun facts on CTA s bus system CTA Bus Service Number of diesel buses 1,862 Number of electric buses 2 Bus routes served 129 Bus stops served 10,768 Daily bus miles traveled 161,192 Annual bus ridership 248.9 M Annual diesel consumption 16.8 M gal Annual diesel cost $33.4 M CTA bus garages 7 2

3. Evolution of CTAs electric bus program Evolution of CTA s electric bus program 2014 2015 2016 2017 2018 2019 2020 2021 RFP Delivery of pilot e-buses; install chargers 2 New Flyer e-buses enter service Planning begins for more e-buses TBD further scale-up of e-buses released for up to 45 e-buses + chargers Contract approved for 20 Proterra e-buses Delivery of remaining e-buses 3

4. Comparison of e Comparison of e- -buses in CTA s fleet buses in CTA s fleet Phase 1 Phase 2 Manufacturer New Flyer Proterra Number purchased 2 20 Year entering service 2014 2019-2020 Charging location Bus garages ( depot charging ) Bus turn-arounds ( en-route charging ) Battery capacity 300 kWh 440 kWh Range 100 miles (run 80) >100 miles (run ??) Charger power 100 kW 450 kW ( fastcharge ) ( slow charge ) Service times AM & PM rush 24/7 Service routes Flexible Fixed: #66 & #124 4

5. Selection of routes and terminals Selection of routes and terminals for en for en- -route e route e- -bus charging bus charging Operational aspects of bus routes Physical aspects of bus turn-arounds Policy considerations Must be able to maintain reliable service with e-buses. Must align with policy priorities. Must accommodate the operation of e-buses and fast- chargers. Indoor bus garage Route length (time, miles) Layover time at terminals Bus accumulation at terminals Scalability for e-buses Visibility Equity Environmental justice Tourism Education Ability to do CTA construction Available space Layout Lane/bay configuration Bypass lanes 5

6. Current example: Current example: Navy Pier bus turn Navy Pier bus turn- -around around 6

7. Considerations for e Considerations for e- -bus scale bus scale- -up up What is the right mix of depot charging vs. en-route charging? Range requirements for routes Capacity requirements for garages Trade-offs in the efficiency of e-buses (miles per kWh) Differential in charger construction/installation costs How can CTA install and operate charging infrastructure most cost-effectively? Strategic planning/design of en-route charging infrastructure Coordination with ComEd Minimize demand fees by managing charging times Consider distributed energy resources to power chargers 7
