2. Why is the FERC-566 data collected?

The FERC-566 information collected by the Commission is used to identify a public utility's large purchasers of electric energy. The FPA requires public utilities to publish and file this list with the Commission. Through a separate FPA required collection, the Form No. 561 "Annual Report of Interlocking Positions" identification is made of public utility board members who are also board members of the utility's largest customers. The Commission uses the information from these two collections to inquire into and determine whether public or private interests will be adversely affected by the holding of officer or director positions of both a public utility and its customers.
