The Transmission Agency of Northern California (TANC) is governed by a Commission consisting of one representative from each of its Member utilities. The TANC Commission annually elects a Chair and four Vice Chairs, of whom one also serves as Secretary, from among its Commissioners.
TANC’s General Manager is responsible for the day to day management and operation of TANC. This responsibility extends to all TANC’s activities including management and oversight of contracts. The General Manager reports directly to the TANC Commission and receives policy guidance from the Commission.
