The Wisconsin Public Service Commission (PSC) has drafted a 425-page (plus appendices) environmental impact statement (EIS) as part of its investigation into restructuring (Docket No. 05-EI-114). The EIS examines a number of different proposed models. The "status quo" model would maintain the present regulatory structure, but the PSC admitted that the present rate case structure is time-consuming and does not respond quickly to changed circumstances.
The "plausible extreme" model proposes a single transmission system owner. Any firm would be allowed to own or construct generation facilities, and existing utility generation assets would be divested through a public auction or bidding process. The distribution system would be separated into a regulated monopoly of distribution lines, and an unregulated retail service entity.
