Hawaiian Electric Featured Case Study: HDOT Fleet Electrification

Hawaiian Electric highlighted the Hawaii’s Department of Transportation’s case study this week, showcasing impressive strides toward the State’s sustainability goals. HDOT continues to expand its EV fleet and charging infrastructure across the islands, and it hasn’t paid a cent upfront for any of it.

Through a statewide, service-based contract with Sustainability Partners, HDOT and other state and county agencies can acquire EVs and charging infrastructure on a per-mile cost basis instead of buying the assets outright. HDOT started with 43 Tesla Model Ys and 43 Level 2 chargers, then scaled to 113 vehicles and 24 more chargers as the program proved successful. The agency pays roughly $1.49 per mile, or about $600 per month per EV on average, covering the vehicle, outfitting, and the charging infrastructure behind it, while cutting maintenance costs by at least 50% compared to its traditional gas-powered fleet.

The results speak for themselves, and it continues to be an honor to serve HDOT and the other agencies working to modernize their essential infrastructure and reach their sustainability goals.
