Section PSC 111.43 - Data from transmission providers

Each transmission provider shall submit all of the following data, except that if the data have been previously filed with the commission, the transmission provider may identify the applicable filing instead of providing duplicate data:

(1) NEW HIGH-VOLTAGE TRANSMISSION LINES. A complete description of each high-voltage transmission line that the transmission provider intends to own in whole or in part, on which construction is planned to commence within 7 years, including all of the following:

(a) Endpoints of the line.

(b) Proposed corridors.

(c) Nominal operating voltage.

(d) Nominal voltage of construction class.

(e) Needed substation modifications.

(f) Estimated cost.

(2) PLANS FOR PRESERVING TRANSMISSION ADEQUACY.

(a) In this subsection, "long-term" study excludes all of the following:

1. Routine, commercial transfer capability and operations studies.

2. Customer-specific transmission studies.

(b) The results and assumptions of each long-term study undertaken by transmission providers, jointly or individually, within the past 2 years or subsequent to the data filing for the last SEA, that examines future transmission transfer capabilities across boundaries of reliability council regions, subregions, or control areas or across the borders of Wisconsin. The results and assumptions of each long-term study about the effect of transmission system reinforcement on transfer capability shall be included in the data submitted under this paragraph.

(c) A complete FERC Form 715 for each of the most recent 2 years available, and any documents or data cited on Form 715 that are not published by the Wisconsin commission.

(d) The results and assumptions of each long-term, local load serving study the transmission provider used to establish the need for the high-voltage transmission lines described in sub. (1), including all discussions of project need and alternatives that may be part of the study.

(3) POWER FLOW CASES.

(a) For each of the 7 years encompassing the SEA, the most recent power flow base case undertaken by the reliability council in which the transmission provider is located, for each of the following conditions:

1. Summer peak.

2. Winter peak.

3. Off-peak.

(b) The base cases in par. (a) need only be submitted if the commission requests that they be filed.

(4) USE OF THE TRANSMISSION SYSTEM. If the transmission provider charges a tariffed amount for use of its transmission system, monthly data, for the 7-year period encompassing the SEA, on total transfer capability, available transfer capability and confirmed reservations for the use of the transmission system. Total transfer capability and available transfer capability shall be calculated in accordance with the provider's obligations, under, to calculate these values. Reservation data under this subsection shall concern only those reservations that are firm and of monthly duration or longer. Data shall include any transmission margins applied in the calculation of available transfer capability and any other use of the transmission system relevant to the calculation of monthly available transfer capability, including use by the transmission provider to meet existing commitments.
