The Upper Cumberland Electric Membership Cooperative's Cookville service center houses many functions. The front portion of the building has lobby with teller lines for bill payment, offices, engineering space, meeting rooms, locker / changing rooms, breakroom and crew rooms. The back of the building houses a large warehouse connected to completely enclosed vehicle bays. Each of the 14 bays backs up to a loading dock connected to the warehouse to increase loading speed. The bays have overhead coiling doors to allow trucks to be loaded / unloaded in even the most adverse conditions. Each bay can double as vehicle storage where trucks can be pre-loaded and remain in a secure environment to prevent theft and loss.
