2 Attachment A

NOTICE OF RATE CH.ANGE REQUEST

On February 16, 2018 CenterPoint Energy Houston Electric LLC (CenterPoint Energy") filed its Application to revise its Wholesale Transmission Rates approved in Docket No. 47610 on November 9, 2017. CenterPoint Energy's Application seeks an interim adjustment to the previously approved transmission cost of service and wholesale transmission rate to reflect a reduction in the federal income tax rate from 35% to 21%, a reduction in transmission rate base for the estimated Excess Deferred Federal Income Tax (EDFIT) attributable to the change in Accumulated Deferred Federal Income Tax related to all incremental transmission plant investments added since the last rate case in Docket No. 38339 and the inclusion of amortized transmission plant EDFIT related to protected property, plant and equipment using the Average Rate Assumption Method (ARAM). If approved, the total transmission rate base interim decrease will be $101,658,253 with a total revenue requirement interim decrease of $41,647,895 from the approved amounts in Docket No. 47610 of $389,483,333 to $347,835,438 and a revised interim wholesale transmission rate of $5,138.64 per MW from the previously approved $5,753.91 per MW. The proposed interim revenue requirement decrease represents an approximate 10.7% decrease in CenterPoint Energy s wholesale transmission revenue requirement approved in Docket No. 47610. CenterPoint Energy has requested an effective date for the interim wholesale transmission rate of March 23, 2018.

Because the Application requests a revision to CenterPoint Energy's wholesale transmission rate to reflect those changes noted above, affected customers include all distribution service providers who pay wholesale transmission charges pursuant to the Substantive Rules of the Public Utility Commission of Texas.

A complete copy of CenterPoint Energy's Application to revise its TCOS from Docket No. 47610 is available for inspection at 1111 Louisiana, Houston Texas, 77002.

Persons who wish to intervene in or comment upon these proceedings should notify the Public Utility Commission of Texas as soon as possible, as an intervention deadline will be imposed. A request to intervene or request for further information should be made to the Public Utility Commission of Texas, P.O. Box 13326, Austin, Texas 78711-3326 and reference Docket No. 48065. Further information may also be obtained by calling the Public Utility Commission of Texas at (512) 936-7120 or (888) 782-8477. Hearing-and-speech-impaired individuals with text telephones (TTY) may contact the commission at (512) 936-7136. CenterPoint Energy has requested an intervention deadline of 21 days after the filing of the application. If CenterPoint Energy's request is granted, the intervention deadline will be March 9, 2018.
