The Center for Transportation and the Environment is partnering with the Department of Transportation Services for the City and County of Honolulu (DTS) to deploy five GILLIG electric buses with depot charging. Hawaii enacted a law requiring 100% renewable electric sources as well as a goal to reduce petroleum use in Hawaii’s transportation center – which accounts for two-thirds of the state’s overall energy usage. This project is unique in that the buses will be charged during the day to take advantage of the renewable energy made available by the abundant solar and wind energy available on the island. Our project with DTS will help them get closer to their goal and diversify Hawaii’s Renewable Portfolio Standard. The project was made possible by the funding of the Low-No Grant program through the Federal Transit Administration (FTA).
