CenterPoint-TDU Rate Settlement Would Lower Monthly Flat Charges For Small Customers

The unopposed stipulation among parties in the base rate proceeding of CenterPoint Energy Houston Electric (CenterPoint Houston or CNP), currently before the Texas PUC, would reduce the amount charged to retail electric providers under flat monthly charges, and would also set the level for a rider to refund amounts related to tax law changes.

Several key terms of the stipulation had been first reported by EnergyChoiceMatters.com on January 22. The full settlement has now been filed, with additional terms.

The stipulation provides that CenterPoint Houston will recover all existing and future transmission-related costs through its transmission cost recovery factor (TCRF) instead of through base rates.

The Distribution Cost Recovery Factor will be set to zero.

Furthermore, CenterPoint Houston will not file a DCRF proceeding during the 2020 calendar year. When updating its distribution rate base through future DCRF proceedings, CenterPoint Houston will update its distribution rate base to account for the effects of changed accumulated deferred federal income tax (ADFIT) and excess deferred income tax (EDIT) regulatory liability balances, in each proceeding requesting an update of its distribution rates.

The stipulation would continue to assess the CNP monthly flat customer charge on the basis of per Retail Customer per Month

However, the monthly flat metering charge would be revised to be charged on the basis of per Meter per Month, rather than on a per-customer basis

For customers with a single meter (putting aside any additional costs from the new per-meter allocation), the combined monthly flat charge (customer and metering) would decrease by $1.08 for residential customers, and $1.44 for Secondary Less Than Or Equal To 10 kVA customers

Under the stipulation, a new Rider UEDIT - Unprotected Excess Deferred Income Taxes Credit will refund to REPs certain excess deferred income tax amounts.

CenterPoint Houston shall refund through Rider UEDIT and its Wholesale Transmission Service tariff an unprotected excess deferred income tax (UEDIT) amount of $64,903,763, protected excess deferred income tax amount of $18,659,227, and gross up of $21,886,079 for a total UEDIT refund of $105,449,069 plus carrying costs. The refund and amortization period for UEDIT for Residential Service, Secondary Service Less Than or Equal to 10 KVA, Street Lighting Service, and Miscellaneous Lighting Service shall be approximately 30 months beginning with the effective date of the rates authorized in the rate case. The refund and amortization period for UEDIT for Secondary Service Greater Than 10 KVA, Primary Service, and Transmission Service shall be approximately 36 months beginning with the effective date of the rates authorized in the rate case

The refunds to be provided to REPs shall be as follows

Lighting ($0.000919) Per kWh 30 Months * Per Billing kVA ^ Per 4CP kVA 

CenterPoint Houston agrees to reimburse cities participating in the proceeding for rate case expenses incurred in all dockets subject to Docket No. 49595.

However, under the stipulation, "CenterPoint Houston agrees not to seek recovery of rate case expenses requested in Docket No. 49595, including expenses associated with this proceeding."

As a result of the stipulation, the key TDU charges that will result from the rate case are as follows for residential and small commercial customers (note: riders not impacted by the rate case such as EECRF and ADFITC are not listed)
