Heading: Comparison with Michigan-Wisconsin Pipe Line Co.

Text: 81 The Commission found that after introduction of LNG, Southern's system resembled Michigan-Wisconsin Pipe Line Company's system. In reviewing that company's system in Michigan-Wisconsin Pipe Line Co., 34 F.P.C. 621 (1965), the Commission found that the systemwide method of allocating transmission costs was not unreasonable or discriminatory. 34 The pipeline in Michigan-Wisconsin is shaped like a Y with one arm of the Y extending into Michigan and the other arm of the Y into Wisconsin. The similarities noted by the Commission were that on both pipelines, gas from the primary supply source flowed through the entire system and was physically received by all customers. Gas received from the downstream end in both systems, however, does not physically reach all upstream customers. Nevertheless, on both systems, all customers benefit from the additional volumes of gas introduced downstream because of the increased flexibility and reliability of the system. 82 Mississippi Valley points to differences between the two systems which it claims makes the Commission's comparison arbitrary and unreasonable. 35 We find none of these differences compelling. We defer to the expertise of the Commission. The Commission's finding of similarity falls well within the scope of those judgments presumed valid. 83
