Income Tax Disclosure [Abstract]

Schedule of Effective Income Tax Rate Reconciliation

The Registrants reported the following effective tax rates for the periods presented:

	Three Months Ended March 31,
	2026		2025
CenterPoint Energy (1)	23	%	21	%
Houston Electric (2)	19	%	19	%
CERC (3)	25	%	25	%

(1)CenterPoint Energy’s higher effective tax rate for the three months ended March 31, 2026 compared to the three months ended March 31, 2025 was due primarily to a decrease in excess deferred income tax amortization of a regulatory liability resulting from the sale of Louisiana and Mississippi natural gas LDC businesses in the first quarter of 2025.

(2)Houston Electric’s effective tax rate for the three months ended March 31, 2026 compared to the three months ended March 31, 2025 was unchanged.

(3)CERC’s effective tax rate for the three months ended March 31, 2026 compared to the three months ended March 31, 2025 was unchanged. The impact of the decrease in excess deferred tax amortization of a regulatory liability resulting from the sale of Louisiana and Mississippi natural gas LDC businesses in the first quarter of 2025 offsets the decrease in state taxes from the sale of these businesses.
