Equity Return

The Registrants are at times allowed by a regulator to defer an equity return as part of the recoverable carrying costs of a regulatory asset. A deferred equity return is capitalized for rate-making purposes, but it is not included in the Registrant’s regulatory assets on its Condensed Consolidated Balance Sheets. The allowed equity return is recognized in the Condensed Statements of Consolidated Income as it is recovered in rates. The recoverable allowed equity return not yet recognized by the Registrants is as follows:

	June 30, 2021						December 31, 2020
	CenterPoint Energy (1)		Houston Electric (2)		CERC (3)		CenterPoint Energy (1)		Houston Electric (2)		CERC (3)
	(in millions)
Allowed equity return not recognized	$	217	$	121	$	14	$	229	$	137	$	13

(1)In addition to the amounts described in (2) and (3) below, CenterPoint Energy’s allowed equity return on post in-service carrying cost generally associated with investments in Indiana.

(2)Represents Houston Electric’s allowed equity return on its true-up balance of stranded costs, other changes and related interest resulting from the formerly integrated electric utilities prior to Texas deregulation to be recovered in rates through 2024 and certain storm restoration balances pending recovery in the next rate proceeding. The actual amounts recognized are adjusted at least annually to correct any over-collections or under-collections during the preceding 12 months.

(3)CERC’s allowed equity return on post in-service carrying cost associated with certain distribution facilities replacements expenditures in Texas.

The table below reflects the amount of allowed equity return recognized by each Registrant in its Condensed Statements of Consolidated Income:

February 2021 Winter Storm Event

In February 2021, certain of the Registrants’ jurisdictions experienced an extreme and unprecedented winter weather event that resulted in prolonged freezing temperatures, which impacted their businesses. In Texas, the February 2021 Winter Storm Event caused an electricity generation shortage that was severely disruptive to Houston Electric’s service territory and the wholesale generation market. While demand for electricity reached extraordinary levels due to the extreme cold, the supply of electricity significantly decreased in part because of the inability of certain power generation facilities to supply electric power to the grid. Houston Electric does not own or operate any electric generation facilities. It transmits and distributes to customers of REPs electric power that the REPs obtain from power generation facilities owned by third parties. ERCOT serves as the independent system operator and regional reliability coordinator for member electric power systems in most of Texas. To comply with ERCOT’s orders, Houston Electric implemented controlled outages across its service territory, resulting in a substantial number of businesses and residents being without power, many for extended periods of time, in compliance with ERCOT’s directives as an emergency procedure to avoid prolonged large-scale state-wide blackouts and long-term damage to the electric system in Texas. In anticipation of this weather event, Houston Electric implemented its emergency operations

plan’s processes and procedures necessary to respond to such events, including establishing an incident command center and calling for mutual assistance from other utilities where needed, among other measures. Throughout the February 2021 Winter Storm Event, Houston Electric remained in contact with its regulators and stakeholders, including federal, state and local officials, as well as the PUCT and ERCOT.

The February 2021 Winter Storm Event also impacted wholesale prices of CenterPoint Energy’s and CERC’s natural gas purchases and their ability to serve customers in their Natural Gas service territories, including due to the reduction in available natural gas capacity and impacts to CenterPoint Energy’s and CERC’s natural gas supply portfolio activities, and the effects of weather on their systems and their ability to transport natural gas, among other things. The overall natural gas market, including the markets from which CenterPoint Energy and CERC sourced a significant portion of their natural gas for their operations, experienced significant impacts caused by the February 2021 Winter Storm Event, resulting in extraordinary increases in the price of natural gas purchased by CenterPoint Energy and CERC.

On February 13, 2021, the Railroad Commission authorized each Texas natural gas distribution utility to record in a regulatory asset the extraordinary expenses associated with the February 2021 Winter Storm Event, including, but not limited to, natural gas cost and other costs related to the procurement and transportation of natural gas supply, subject to recovery in future regulatory proceedings. The Texas governor signed legislation in June 2021 that authorizes the Railroad Commission to use securitization financing and the issuance of customer rate relief bonds for recovery of extraordinary natural gas costs incurred by natural gas utilities as a result of the February 2021 Winter Storm Event. In addition, CenterPoint Energy’s and CERC’s Natural Gas utilities in jurisdictions outside of Texas deferred under-recovered natural gas cost as regulatory assets under existing recovery mechanisms and are seeking recovery of the increased cost of natural gas. As of June 30, 2021, CenterPoint Energy and CERC have recorded current regulatory assets of $325 million and $222 million included in Prepaid expenses and other current assets, respectively, and non-current regulatory assets of $1,774 million and $1,763 million, respectively, associated with the February 2021 Winter Storm Event.

Amounts for the under recovery of natural gas costs are reflected in regulatory assets and are probable of recovery; however, the timing of recovery for the estimated incremental natural gas cost attributable to the February 2021 Winter Storm Event within each regulatory asset remains uncertain in some jurisdictions. Recovery of natural gas costs within the regulatory assets are subject to customary regulatory prudency reviews in all jurisdictions that may impact the amounts ultimately recovered. For example, the Minnesota Attorney General’s Office and Department of Commerce have proposed significant disallowances for all natural gas utilities, resulting in a potential disallowance of up to approximately $290 million for CenterPoint Energy and CERC. The natural gas costs in Minnesota were incurred in accordance with the plan on file with the MPUC and remain probable of recovery. Additionally, due to the uncertainty of timing and method of recovery in some jurisdictions, CenterPoint Energy and CERC may not earn a return on amounts deferred in the regulatory assets associated with the February 2021 Winter Storm Event.

On February 21, 2021, in response to the 2021 February Winter Storm Event, the PUCT issued an order prohibiting REPs from sending a request to TDUs to disconnect such REPs’ customers for non-payment, effective February 21, 2021. As a result of this order, Houston Electric did not execute any requests for disconnection from any REPs until the PUCT issues orders for disconnects to resume. In June 2021, the PUCT issued an updated order relating to disconnections and REPs resumed the distribution of disconnection notices thereafter. As of June 30, 2021, as authorized by the PUCT, CenterPoint Energy and Houston Electric recorded a regulatory asset of $8 million for bad debt expenses resulting from REPs’ default on their obligation to pay delivery charges to Houston Electric net of collateral. Additionally, as of June 30, 2021, CenterPoint Energy and Houston Electric recorded a regulatory asset of $12 million to defer operations and maintenance costs associated with the February 2021 Winter Storm Event.

See Notes 12 and 14(d) for further information regarding debt financing transactions and litigation related to the February 2021 Winter Storm Event, respectively.

COVID-19 Regulatory Matters

Governors, public utility commissions and other authorities in the states in which the Registrants operate issued a number of different orders related to the COVID-19 pandemic, including orders addressing customer non-payment and disconnection. Although the disconnect moratoriums have expired or are set to expire in the third quarter of 2021 in the Registrants’ service territories, CenterPoint Energy continues to support those customers who may need payment assistance, arrangements or extensions.

The COVID-19 ERP allows program expenses to be recovered in rates. CenterPoint Energy’s and Houston Electric’s COVID-19 ERP regulatory assets were $-0- as of June 30, 2021 and $6 million as of December 31, 2020.

Commissions in all of Indiana Electric’s and CenterPoint Energy’s and CERC’s Natural Gas service territories have either (1) issued orders to record a regulatory asset for incremental bad debt expenses related to COVID-19, including costs associated with the suspension of disconnections and payment plans or (2) provided authority to recover bad debt expense through an existing tracking mechanism. CenterPoint Energy and CERC have recorded estimated incremental uncollectible receivables to the associated regulatory asset of $28 million and $26 million, respectively, as of June 30, 2021 and $22 million and $19 million, respectively, as of December 31, 2020.

In some of the states in which the Registrants operate, public utility commissions have authorized utilities to employ deferred accounting authority for certain COVID-19 related costs which ensure the safety and health of customers, employees, and contractors, that would not have been incurred in the normal course of business. CERC’s Natural Gas service territories in Minnesota and Arkansas will include any offsetting savings in the deferral. Other jurisdictions where the Registrants operate may require them to offset the deferral with savings as well. The Arkansas FRP, filed on April 5, 2021, included a request for (1) the regulatory asset as of September 30, 2020 in working capital for the 2021 historical year using a thirteen-month average of the asset balance; (2) the regulatory asset as of September 30, 2020 in working capital for the 2021 projected year using a thirteen-month average of the asset balance; and (3) the amortization of the balance over the 2021 projected year twelve-month period beginning October 1, 2021. The Mississippi RRA, filed on April 30, 2021, included the unamortized balance of the regulatory asset as of December 31, 2020 in rate base per Docket No. 2018-AD-141 Order Authorizing Utility Response and Accounting for COVID-19.
