Electric (CenterPoint Energy and Houston Electric)
Properties
All of Houston Electric’s properties are located in Texas. Its properties consist primarily of high-voltage electric transmission lines and poles, distribution lines, substations, service centers, service wires, telecommunications networks and meters. Most of Houston Electric’s transmission and distribution lines have been constructed over lands of others pursuant to easements or along public highways and streets under franchise agreements and as permitted by law. All real and tangible properties of Houston Electric, subject to certain exclusions, are currently subject to the lien of the M&DOT and the lien of the General Mortgage, which is junior to the lien of the M&DOT. No first mortgage bonds are outstanding under the M&DOT and Houston Electric is contractually obligated to not issue any additional first mortgage bonds under the M&DOT. Houston Electric is undertaking actions to release the lien of the M&DOT and terminate the M&DOT. For information related to debt outstanding under the General Mortgage, see Note 12 to the consolidated financial statements.
Indiana Electric’s properties are primarily located in Indiana. They consist of transmission lines in Indiana and Kentucky, distribution lines, substations, service centers, coal-fired generating facilities, gas-fired turbine peaking units, a landfill gas electric generation facility and solar generation facilities.

(1) While Indiana Electric’s 2025 IRP (similar to previous IRPs) preferred portfolios included the retirement of F.B. Culley Unit 2, a coal-fired generation unit, by the end of 2025, the U.S. Department of Energy issued an emergency 202(c) order in December 2025 directing Indiana Electric to continue operating the unit through March 23, 2026. For further information about F.B. Culley 2, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Regulatory Matters” in Item 7 of Part II of this report, which discussion is incorporated herein by reference.

(3) Excludes 1.5% participation in OVEC. See Item 1. Business for more details.
Natural Gas Combustion Turbines. In 2022, Indiana Electric received approval from the IURC for a CPCN seeking approval to construct two natural gas combustion turbines to replace portions of its existing coal-fired generation fleet. In the second quarter of 2025, 230 MW of the facility was placed in service, and due to a transformer manufacturing issue, the remaining 230 MW of the facility was placed in service in the third quarter of 2025. For further information, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Regulatory Matters” in Item 7 of Part II of this report, which discussion is incorporated herein by reference.
Solar. On February 7, 2023, Indiana Electric filed a CPCN with the IURC to approve an amended BTA to purchase the 191 MW Posey Solar project. On September 6, 2023, the IURC issued an order approving the CPCN. On March 7, 2025, SIGECO completed the acquisition of Posey Solar. The Posey Solar project was placed in service in the second quarter of 2025. For further information about Indiana Electric’s BTAs, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Regulatory Matters” in Item 7 of Part II of this report, which discussion is incorporated herein by reference.
TEEEF. As allowed by a law enacted by the Texas legislature after the February 2021 Winter Storm Event and amended in 2023, Houston Electric entered into leases for 15 large (27 MW to 32 MW) and five medium (5.7 MW) TEEEF. In June 2025, Houston Electric entered into the ERCOT Transaction, subject to PUCT approval, to release its large TEEEF units to ERCOT at CPS Energy facilities to serve the greater San Antonio region until March 2027 unless terminated earlier pursuant to the provisions of the ERCOT Transaction, reduce its TEEEF fleet capacity and reduce its rates to reflect the removal of the large TEEEF units from its fleet. In November 2025, Houston Electric also proposed to release the five medium (5.7 MW) TEEEF units from its TEEEF fleet and remove the associated lease costs effective January 1, 2026. On February 13, 2026, Houston Electric requested continued abatement until February 27, 2026 due to continued settlement discussions. As of December 31, 2025, Houston Electric leased 519 MW of TEEEF on a long-term basis. For more information, see Note 7 and Note 19 to the consolidated financial statements.

Natural Gas (CenterPoint Energy and CERC)
CenterPoint Energy’s and CERC’s natural gas distribution businesses use various third-party storage services or owned natural gas storage facilities to meet peak-day requirements and to manage the daily changes in demand due to changes in weather. CenterPoint Energy’s and CERC’s natural gas distribution businesses may also supplement contracted supplies and storage from time to time with stored LNG and propane-air plant production.
As of December 31, 2025, CenterPoint Energy’s and CERC’s natural gas distribution businesses owned and operated the following natural gas facilities:
No. of Assets Storage Capacity (Bcf) Working Capacity (Bcf) Maximum Daily Withdrawal Rate (MMcf)

The table below reflects the approximate total linear miles of distribution and transmission mains owned by CenterPoint Energy’s and CERC’s natural gas distribution businesses as of December 31, 2025:
CenterPoint Energy CERC
All Locations 72,000 69,000
Indiana and Ohio (1)
23,000 20,000
(1) Linear miles of distribution and transmission mains attributable to CEOH were approximately 6,000 miles.
CenterPoint Energy’s and CERC’s natural gas distribution businesses owned mains varying in size from one-half inch to 24 inches in diameter. CenterPoint Energy’s and CERC’s natural gas distribution businesses in Indiana and Ohio own mains that are located in Indiana and Ohio except for, in the case of CenterPoint Energy, pipeline facilities extending from points in northern Kentucky to points in southern Indiana so that gas may be transported to Indiana and sold or transported to customers in Indiana. Generally, in each of the cities, towns and rural areas served by CenterPoint Energy’s and CERC’s natural gas distribution businesses, CenterPoint Energy and CERC own the underground gas mains and service lines, metering and regulating equipment located on customers’ premises and the district regulating equipment necessary for pressure maintenance. With a few exceptions, the measuring stations at which CenterPoint Energy’s and CERC’s natural gas distribution businesses receive gas are owned, operated and maintained by others, and their distribution facilities begin at the outlet of the measuring equipment. These facilities, including odorizing equipment, are usually located on land owned by suppliers.
As of December 31, 2025, CenterPoint Energy and CERC, through CEIP, owned and operated over 208 miles of intrastate pipeline in Texas. On March 31, 2025, CenterPoint Energy, through its subsidiary CERC Corp., completed the sale of its Louisiana and Mississippi natural gas LDC businesses, which included the intrastate pipelines owned by CEIP in Louisiana. On October 20, 2025, CenterPoint Energy, through CERC Corp., entered into the Ohio Securities Purchase Agreement to sell all of the issued and outstanding equity interests in CEOH. The transaction is expected to close in the fourth quarter of 2026, subject to the satisfaction of customary closing conditions.
