Appellee, Public Utility Commission of Texas // Cross-Appellee, CPS Energy, Time Warner Cable Texas LLC and Southwestern Bell Telephone Company d/b/a AT&T Dear Mr. Kyle: To the extent the State’s letter dated April 20, 2015 intends to argue that the Commission’s declarations regarding amendments to the applicable federal regulations are not a valid directive with respect to determining the rate cap established by PURA § 54.204(c) after the effective date of the amendments (June 8, 2011), Time Warner Cable Texas LLC disagrees. We request that the Court allow briefing from the parties before ruling on this issue that was raised after the submission of all briefs and only two days before oral argument.
