Moving Together Conference Martha s Vineyard and Electric Transit Angie Grant, Administrator Martha s Vineyard Transit Authority Presenter s Logo
Martha s Vineyard Operating Environment Historic communities with narrow roads Rural routes rolling hills Traffic and congestion in the summer time Very high ridership in summer ome routes carry 70 riders per trip Vehicles deployed for long days (250 350 miles) New drivers trained every summer Fuels shipped by barge and truck 2

VTA Perspective - 2015/2016 ignificant growth and development over last 20 years Ridership, vehicles/fleet size, revenue Ready for next challenge Riders and communities want cleaner, quieter vehicles 70% of fleet reaching useful life by 2022 Diesel fuel is inexpensive now, but vehicles are difficult to maintain Martha s Vineyard focused on sustainability and resiliency 5
Alternative Fuels Assessment Evaluated: clean diesel, biodiesel, propane, CNG, LNG, renewable natural gas, hybrid-electric and electric Considered costs, benefits and available technology No perfect answer Lowest cost options are most polluting and least reliable Lower pollution and more reliable options are expensive 6
Electric Vehicles trengths Modern technology industry moving that way Quiet, zero emission vehicles Potential for operating costs savings fuel and maintenance Operational reliability Concerns Cost vehicles are more expensive Range current vehicles won t work on all of the VTA routes Infrastructure changes 7
Flexibility Required Open to Rethink Operations horter routes and/or in-route charging wapping buses mid-day or at shift change Work with Rapidly Developing Technology Energy density in battery is increasing = longer ranges Predictable energy costs Willingness to Develop New ystems Vehicle fueling Vehicle maintenance Energy storage systems olar panels 8
VTA Project Elements Vehicles 30 and 35 Battery Electric Buses Depot Charging Infrastructure Improvements Energy torage ystem On-ite olar / PV ystem In-route Charging
Buses 30 and 35 buses BYD Technology Extended range ~ 150-230 miles Depot (slow) chargers - One charger per bus - Plus one charger for maintenance facility - Another mobile charger Cost per bus ~ $750,000 (35 ) Cost per bus ~ $550,000 (30 ) 10
Depot Chargers (EVE) 30 Bus - Battery size 180 kwh (150 miles) - Charging capacity - 80 kw 35 Bus - Battery size 370 kwh (230 miles) - Charging capacity - 80 kw 2 5 hours to fully charge bus, depending on starting point Cost - one charger (EVE) included in cost of bus 11
Infrastructure Improvements Increase capacity of electrical infrastructure Coordinate with utility (Eversource) on work scope Phase 1 (2018) - Prep for 6 buses on site - Increase capacity for up to 480 kw - Electricity consumption increase by 1 MW per day Costs and timeline being finalized 12
On-ite olar Rooftop solar (~ 200 MWh) olar canopy (~ 600 MWh) - Park buses under canopy Total generation ~800 MWh Private sector partnership - Private partner: takes tax credit and operator owns and installs panels - ells electricity to grid for set period of time - After time period met, use energy to charge energy storage system and power system VTA costs are for electrical infrastructure 13
Energy torage ystems Resiliency Charge buses when power is down ource of energy during emergencies Control energy costs Charge E at night with low rates Charge E during the day from grid Cost is about ~ $1 million Able to charge 6 8 buses 14
On-Route Charging 15
Inspiration and Experience Antelope Valley Transit Authority (AVTA) Northern Los Angles County, CA Transitioning to 100% electric, with inductive charging Willing to share experiences Demonstration Bus on-site August, 2017 ite Visits AVTA, Facebook and tanford BYD Factory 16
tatus and Next teps Ordered four BYD electric buses Funded with existing programs (RTACAP) cheduled to arrive in June 2018 tart installing chargers winter 2018 tarted working on infrastructure improvements Initial site design work completed ubmitted work order to Eversource 17
tatus and Next teps RFP for solar expected in late October 2017 Will require more coordination with utility Ideally install solar panels in 2018 RFP for storage expected in December 2017 Looking for funding for next steps Awarded $1.2 million from FTA Low or No Vehicle Emissions 2 buses and cost share for storage system Advancing Commonwealth Energy torage (ACE) Grant Applied for $1 million for storage Looking for funding for inductive in-route charging in Church t. Edgartown 18
