. This case,- -as- the-respondent Commission and the intervenor have formally advised the court, is essentially similar to Memphis Light, Gas & Water Division v. Federal Power Commission, 1957, 102 U.S.App.D.C.-, 250 F.2d 402. We think it must.be governed by like principles. Accordingly, the order of the Commission will be set aside and relief granted along the lines stated in Memphis. Additional contentions made by the petitioner need not be reached.

So ordered.
