Mountain Line Electric Bus Charging Infrastructure
Cushing Terrell provided electrical construction documents, cost estimates, and construction administration services to upgrade the electrical service at the Mountain Line Bus Depot to accommodate new electric bus chargers. Mountain Line Bus is replacing its existing diesel bus fleet with new, emissions-free, electric buses. The project required the installation of a new electric service at the main bus barn building and a new electrical service in a detached bus storage canopy.
Cushing Terrell is currently conducting a feasibility study to install a battery energy storage system (BESS) at the Mountain Line Bus Depot to help offset the peak electrical demand created from the electric bus chargers. The proposed BESS batteries will be charged with grid power when buses are dispatched; the BESS stored energy will then be utilized to charge bus batteries at night. The system will reduce peak utility demand charges by 90% and can be utilized for charging bus batteries in the event of a grid power outage.
