the ability of FERC to ensure that shippers of natural gas on interstate pipelines pay just and reasonable rates. Absent legislative changes to broaden FERC authority under NGA Section 5, however, it will take significant collective shipper efforts, and a determined FERC, to assure that gas transportation rates remain just and reasonable.

4. Many variables determine a pipeline’s cost of service. The passage of time doesn’t always lead to a decline in the cost of service for certain contracted capacity, particularly for pipelines requiring major capital improvements to existing infrastructure. In addition, some pipelines may seek to levelize their rates over a given time period, which would affect year-by-year ROE calculations.

10. This assumption is consistent with the commission’s representative ruling in Ingleside Energy Center, rejecting the use of a 70 percent equity ratio proposed by the developer and required that a 50/50 debt-to-equity capital structure be used for ratemaking purposes. See 112 FERC ¶ 61101, 2005.

11. This 14 percent return on equity was allowed for greenfield pipelines with substantial financial leverage such as Colorado Interstate Gas Co (Docket No. CP03-7), AES Ocean Express (Docket No. CP02-90), Sonora Pipeline LLC (Docket No. CP07-74), Trans-Union Interstate Pipeline (Docket No. CP01-37) and Tractebel Calypso Pipeline (Docket No. CP01-409).

12. The Commission has found that “a large equity ratio is more costly to ratepayers, since equity financing is typically more costly than debt financing, and also because the interest on indebtedness is tax deductible.” See Ingleside Energy Center , 112 FERC ¶ 61101, 2005.
