Segment Reporting [Abstract]  
Reportable Segments Reportable Segments
The Registrants’ determination of reportable segments considers the strategic operating units under which the CODM manages sales, allocates resources and assesses performance of various products and services to wholesale or retail customers in differing regulatory environments.
As of March 31, 2025, reportable segments by Registrant and information about each Registrant’s CODM were as follows:

CenterPoint Energy

•CenterPoint Energy’s Electric reportable segment consists of electric transmission and distribution services in the Texas Gulf Coast area in the ERCOT region and electric transmission and distribution services primarily to southwestern Indiana and includes power generation and wholesale power operations in the MISO region.

•CenterPoint Energy’s Natural Gas reportable segment consists of (i) intrastate natural gas sales to, and natural gas transportation and distribution for residential, commercial, and industrial customers in Indiana, Minnesota, Ohio and Texas; and (ii) permanent pipeline connections through interconnects with various interstate and intrastate pipeline companies through CEIP.

•CenterPoint Energy’s Corporate and Other category consists of corporate support operations that support all of CenterPoint Energy’s business operations. CenterPoint Energy’s Corporate and Other also includes office buildings and other real estate used for business operations.

CenterPoint Energy’s CODM, the President and Chief Executive Officer, evaluates performance for all of its reportable segments based on segment net income. The CODM uses segment net income to allocate resources as part of the budgeting and forecasting process as well as during periodic budget-to-actual reviews.
