The following are updates to that discussion. Fuel and purchased power cost recovery Entergy Arkansas Energy Cost Recovery Rider In March 2017, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.01164 per kWh to $0.01547 per kWh.

The fuel reconciliation settlement was approved by the PUCT in March 2017. Retail Rate Proceedings See Note 2 to the financial statements in the Form 10-K for detailed information regarding retail rate proceedings involving the Utility operating companies. The following are updates to that information. Filings with the APSC 2016 Formula Rate Plan Filing As discussed in the Form 10-K, Entergy Arkansas is required to make a supplemental filing supporting the recovery of certain nuclear costs. In April 2017, Entergy Arkansas filed a motion consented to by all parties requesting that it be permitted to submit its supplemental filing in conjunction with its 2017 formula rate plan filing, scheduled to be made in July 2017. Advanced Metering Infrastructure (AMI) Filing As discussed in the Form 10-K, in September 2016, Entergy Arkansas filed an application seeking a finding from the APSC that Entergy Arkansas’s deployment of advanced metering infrastructure is in the public interest. This matter is pending before the APSC. Filings with the LPSC Retail Rates - Electric 2015 Formula Rate Plan Filing As discussed in the Form 10-K, in May 2016, Entergy Louisiana filed its formula rate plan evaluation report for its 2015 calendar year operations. The LPSC’s review is pending. Also, in November 2016, Entergy Louisiana filed with the LPSC a request to extend the MISO cost recovery mechanism rider provision of its formula rate plan. A procedural schedule was established, including a hearing in July 2017. In March 2017 the LPSC staff submitted direct testimony generally supportive of a one-year extension of the MISO cost recovery mechanism and the intervenor in the proceeding does not oppose an extension for this period of time. Waterford 3 Replacement Steam Generator Project See Note 2 to the financial statements in the Form 10-K for discussion of the Waterford 3 replacement steam generator project prudence review proceeding. The refund to customers of approximately $71 million as a result of the settlement approved by the LPSC was made to customers in January 2017. Union Power Station As a term of the LPSC-approved settlement authorizing the purchase of Power Blocks 3 and 4 of the Union Power Station, Entergy Louisiana agreed to make a filing with the LPSC to review its decisions to deactivate Ninemile 3 and Willow Glen 2 and 4 and its decision to retire Little Gypsy 1. In January 2016, Entergy Louisiana made its compliance filing with the LPSC. Entergy Louisiana, LPSC staff, and intervenors participated in a technical conference in March 2016 where Entergy Louisiana presented information on its deactivation/retirement decisions for these four units in addition to information on the current deactivation decisions for the ten-year planning horizon. Parties have requested further proceedings on the prudence of the decision to deactivate Willow Glen 2 and 4. No party contests the prudence of the decision to deactivate Willow Glen 2 and 4 or suggests reactivation of these units; however, issues have been raised related to Entergy Louisiana’s decision to retire Willow Glen 2 and 4, as opposed to temporarily suspending those units. This matter is pending before an ALJ, with an evidentiary hearing scheduled to commence in July 2017. The ALJ recently dismissed claims of an industrial user regarding a proposed process for future deactivation because the LPSC initiated a generic rulemaking to consider whether the LPSC should review deactivation decisions prior to implementation. Retail Rates - Gas 2016 Rate Stabilization Plan Filing In January 2017, Entergy Louisiana filed with the LPSC its gas rate stabilization plan for the test year ended September 30, 2016. The filing of the evaluation report for test year 2016 reflected an earned return on common equity of 6.37%. As part of the original filing, pursuant to the extraordinary cost provision of the rate stabilization plan, Entergy Louisiana sought to recover approximately $1.5 million in deferred operation and maintenance expenses incurred to restore service and repair damage resulting from flooding and widespread rainfall in southeast Louisiana that occurred in August 2016. Entergy Louisiana requested to recover the prudently incurred August 2016 storm restoration costs over ten years, outside of the rate stabilization plan sharing provisions. As a result, Entergy Louisiana’s filing sought an annual increase in revenue of $1.4 million. Following review of the filing, except for the proposed extraordinary cost recovery, the LPSC staff confirmed Entergy Louisiana’s filing was consistent with the principles and requirements of the rate stabilization plan. The extraordinary cost recovery request associated with the 2016 flood-related deferred operation and maintenance expenses incurred for gas operations was removed from the rate stabilization plan pending LPSC consideration in a separate docket. In April 2017 the LPSC approved a joint report of proceedings and Entergy Louisiana submitted a revised evaluation report reflecting a $1.2 million annual increase in revenue with rates implemented with the first billing cycle of May 2017. Advanced Metering Infrastructure (AMI) Filing As discussed in the Form 10-K, in November 2016, Entergy Louisiana filed an application seeking a finding from the LPSC that Entergy Louisiana’s deployment of advanced electric and gas metering infrastructure is in the public interest. This matter is pending before an ALJ, and an evidentiary hearing is scheduled for September 2017.

The filing is currently subject to MPSC review. Advanced Metering Infrastructure (AMI) Filing As discussed in the Form 10-K, in November 2016, Entergy Mississippi filed an application seeking a finding from the MPSC that Entergy Mississippi’s deployment of advanced metering infrastructure is in the public interest. In May 2017 the Mississippi Public Utilities Staff and Entergy Mississippi entered into and filed a joint stipulation supporting Entergy Mississippi’s filing, and the MPSC issued an order approving the filing without any material changes, finding that Entergy Mississippi’s deployment of AMI is in the public interest and granting a certificate of public convenience and necessity. The MPSC order also confirmed that Entergy Mississippi shall continue to include in rate base the remaining book value of existing meters that will be retired as part of the AMI deployment and also to depreciate those assets using current depreciation rates. Filings with the City Council Retail Rates As discussed in the Form 10-K, in February 2017, Entergy New Orleans filed a proposed implementation plan for the Energy Smart program from April 2017 through March 2020. As part of the proposal, Entergy New Orleans requested that the City Council identify its desired level of funding for the program during this time period and approve a cost recovery mechanism. In April 2017 the City Council approved an implementation plan for the Energy Smart program from April 2017 through December 2019. The City Council directed that the $11.8 million balance reported for Energy Smart funds be used to continue funding the program for Entergy New Orleans’s legacy customers and that the Energy Smart Algiers program continue to be funded through the Algiers fuel adjustment clause, until additional customer funding is required for the legacy customers. The City Council ordered Entergy New Orleans to submit a supplemental and amended implementation plan for program years 8 and 9 of the Energy Smart program (January 2018 through December 2019) in October 2017. Following that filing, the City Council will determine a specific cost recovery mechanism for the program for both legacy and Algiers customers. The City Council will not permit Entergy New Orleans to recover lost contribution to fixed costs for program years 7, 8, or 9 of the Energy Smart program. Internal Restructuring As discussed in the Form 10-K, in July 2016, Entergy New Orleans filed an application with the City Council seeking authorization to undertake a restructuring that would result in the transfer of substantially all of the assets and operations of Entergy New Orleans to a new entity, which would ultimately be owned by an existing Entergy subsidiary holding company. In May 2017 the City Council adopted a resolution approving the proposed internal restructuring pursuant to an agreement in principle with the City Council advisors and certain intervenors. Pursuant to the agreement in principle, Entergy New Orleans will credit retail customers $10 million in 2017, $1.4 million in the first quarter of the year after the transaction closes, and $117,500 each month in the second year after the transaction closes until such time as new base rates go into effect as a result of the anticipated 2018 base rate case. Additionally, if the FERC approves the transaction prior to December 31, 2018, Entergy New Orleans will credit retail customers $5 million in each of the years 2018, 2019, and 2020. Advanced Metering Infrastructure (AMI) Filing As discussed in the Form 10-K, in October 2016, Entergy New Orleans filed an application seeking a finding from the City Council that Entergy New Orleans’s deployment of advanced electric and gas metering infrastructure is in the public interest. In April 2017, Entergy New Orleans received intervenor testimony that is generally supportive of AMI deployment. The City Council’s advisors are scheduled to file testimony in May 2017, and a hearing is currently set for July 2017. Filings with the PUCT Other Filings In September 2016, Entergy Texas filed with the PUCT a request to amend its transmission cost recovery factor (TCRF) rider. The proposed amended TCRF rider is designed to collect approximately $29.5 million annually from Entergy Texas’s retail customers. This amount includes the approximately $10.5 million annually that Entergy Texas is currently authorized to collect through the TCRF rider. In September 2016 the PUCT suspended the effective date of the tariff change to March 2017. In December 2016, Entergy Texas and the PUCT reached a settlement agreeing to the amended TCRF annual revenue requirement of $29.5 million. The PUCT approved the settlement and issued a final order in March 2017. Entergy Texas implemented the amended TCRF rider beginning with bills covering usage on and after March 20, 2017. System Agreement Cost Equalization Proceedings See the Form 10-K for a discussion of the litigation involving the System Agreement at the FERC and in federal courts. Entergy Arkansas Opportunity Sales Proceedings See the Form 10-K for a discussion of the proceeding initiated at the FERC by the LPSC in June 2009. Complaint Against System Energy In January 2017 the APSC and MPSC filed a complaint with the FERC against System Energy. The complaint seeks a reduction in the return on equity component of the Unit Power Sales Agreement pursuant to which System Energy sells its Grand Gulf capacity and energy to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans. Entergy Arkansas also sells some of its Grand Gulf capacity and energy to Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans under separate agreements. The current return on equity under the Unit Power Sales Agreement is 10.94%. The complaint alleges that the return on equity is unjust and unreasonable because current capital market and other considerations indicate that it is excessive. The complaint requests the FERC to institute proceedings to investigate the return on equity and establish a lower return on equity, and also requests that the FERC establish January 23, 2017, as a refund effective date. The complaint includes return on equity analysis that purports to establish that the range of reasonable return on equity for System Energy is between 8.37% and 8.67%. System Energy answered the complaint in February 2017 and disputes that a return on equity of 8.37% to 8.67% is just and reasonable. The City of New Orleans filed comments in February 2017 supporting the complaint. System Energy is recording a provision against revenue for the potential outcome of this proceeding. Action by the FERC is pending.

As part of the original filing, pursuant to the extraordinary cost provision of the rate stabilization plan, Entergy Louisiana sought to recover approximately $1.5 million in deferred operation and maintenance expenses incurred to restore service and repair damage resulting from flooding and widespread rainfall in southeast Louisiana that occurred in August 2016. Entergy Louisiana requested to recover the prudently incurred August 2016 storm restoration costs over ten years, outside of the rate stabilization plan sharing provisions. As a result, Entergy Louisiana’s filing sought an annual increase in revenue of $1.4 million. Following review of the filing, except for the proposed extraordinary cost recovery, the LPSC staff confirmed Entergy Louisiana’s filing was consistent with the principles and requirements of the rate stabilization plan. The extraordinary cost recovery request associated with the 2016 flood-related deferred operation and maintenance expenses incurred for gas operations was removed from the rate stabilization plan pending LPSC consideration in a separate docket. In April 2017 the LPSC approved a joint report of proceedings and Entergy Louisiana submitted a revised evaluation report reflecting a $1.2 million annual increase in revenue with rates implemented with the first billing cycle of May 2017. Advanced Metering Infrastructure (AMI) Filing As discussed in the Form 10-K, in November 2016, Entergy Louisiana filed an application seeking a finding from the LPSC that Entergy Louisiana’s deployment of advanced electric and gas metering infrastructure is in the public interest.

The MPSC order also confirmed that Entergy Mississippi shall continue to include in rate base the remaining book value of existing meters that will be retired as part of the AMI deployment and also to depreciate those assets using current depreciation rates. Filings with the City Council Retail Rates As discussed in the Form 10-K, in February 2017, Entergy New Orleans filed a proposed implementation plan for the Energy Smart program from April 2017 through March 2020.

In April 2017 the City Council approved an implementation plan for the Energy Smart program from April 2017 through December 2019. The City Council directed that the $11.8 million balance reported for Energy Smart funds be used to continue funding the program for Entergy New Orleans’s legacy customers and that the Energy Smart Algiers program continue to be funded through the Algiers fuel adjustment clause, until additional customer funding is required for the legacy customers. The City Council ordered Entergy New Orleans to submit a supplemental and amended implementation plan for program years 8 and 9 of the Energy Smart program (January 2018 through December 2019) in October 2017. Following that filing, the City Council will determine a specific cost recovery mechanism for the program for both legacy and Algiers customers. The City Council will not permit Entergy New Orleans to recover lost contribution to fixed costs for program years 7, 8, or 9 of the Energy Smart program. Internal Restructuring As discussed in the Form 10-K, in July 2016, Entergy New Orleans filed an application with the City Council seeking authorization to undertake a restructuring that would result in the transfer of substantially all of the assets and operations of Entergy New Orleans to a new entity, which would ultimately be owned by an existing Entergy subsidiary holding company. In May 2017 the City Council adopted a resolution approving the proposed internal restructuring pursuant to an agreement in principle with the City Council advisors and certain intervenors. Pursuant to the agreement in principle, Entergy New Orleans will credit retail customers $10 million in 2017, $1.4 million in the first quarter of the year after the transaction closes, and $117,500 each month in the second year after the transaction closes until such time as new base rates go into effect as a result of the anticipated 2018 base rate case. Additionally, if the FERC approves the transaction prior to December 31, 2018, Entergy New Orleans will credit retail customers $5 million in each of the years 2018, 2019, and 2020. Advanced Metering Infrastructure (AMI) Filing As discussed in the Form 10-K, in October 2016, Entergy New Orleans filed an application seeking a finding from the City Council that Entergy New Orleans’s deployment of advanced electric and gas metering infrastructure is in the public interest.

The City Council’s advisors are scheduled to file testimony in May 2017, and a hearing is currently set for July 2017. Filings with the PUCT Other Filings In September 2016, Entergy Texas filed with the PUCT a request to amend its transmission cost recovery factor (TCRF) rider. The proposed amended TCRF rider is designed to collect approximately $29.5 million annually from Entergy Texas’s retail customers. This amount includes the approximately $10.5 million annually that Entergy Texas is currently authorized to collect through the TCRF rider. In September 2016 the PUCT suspended the effective date of the tariff change to March 2017. In December 2016, Entergy Texas and the PUCT reached a settlement agreeing to the amended TCRF annual revenue requirement of $29.5 million. The PUCT approved the settlement and issued a final order in March 2017. Entergy Texas implemented the amended TCRF rider beginning with bills covering usage on and after March 20, 2017.

Complaint Against System Energy In January 2017 the APSC and MPSC filed a complaint with the FERC against System Energy. The complaint seeks a reduction in the return on equity component of the Unit Power Sales Agreement pursuant to which System Energy sells its Grand Gulf capacity and energy to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans. Entergy Arkansas also sells some of its Grand Gulf capacity and energy to Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans under separate agreements. The current return on equity under the Unit Power Sales Agreement is 10.94%. The complaint alleges that the return on equity is unjust and unreasonable because current capital market and other considerations indicate that it is excessive. The complaint requests the FERC to institute proceedings to investigate the return on equity and establish a lower return on equity, and also requests that the FERC establish January 23, 2017, as a refund effective date. The complaint includes return on equity analysis that purports to establish that the range of reasonable return on equity for System Energy is between 8.37% and 8.67%. System Energy answered the complaint in February 2017 and disputes that a return on equity of 8.37% to 8.67% is just and reasonable. The City of New Orleans filed comments in February 2017 supporting the complaint. System Energy is recording a provision against revenue for the potential outcome of this proceeding. Action by the FERC is pending.

This amount includes the approximately $10.5 million annually that Entergy Texas is currently authorized to collect through the TCRF rider. In September 2016 the PUCT suspended the effective date of the tariff change to March 2017. In December 2016, Entergy Texas and the PUCT reached a settlement agreeing to the amended TCRF annual revenue requirement of $29.5 million. The PUCT approved the settlement and issued a final order in March 2017. Entergy Texas implemented the amended TCRF rider beginning with bills covering usage on and after March 20, 2017.

Entergy Arkansas Opportunity Sales Proceedings See the Form 10-K for a discussion of the proceeding initiated at the FERC by the LPSC in June 2009. Complaint Against System Energy In January 2017 the APSC and MPSC filed a complaint with the FERC against System Energy. The complaint seeks a reduction in the return on equity component of the Unit Power Sales Agreement pursuant to which System Energy sells its Grand Gulf capacity and energy to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans. Entergy Arkansas also sells some of its Grand Gulf capacity and energy to Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans under separate agreements. The current return on equity under the Unit Power Sales Agreement is 10.94%. The complaint alleges that the return on equity is unjust and unreasonable because current capital market and other considerations indicate that it is excessive. The complaint requests the FERC to institute proceedings to investigate the return on equity and establish a lower return on equity, and also requests that the FERC establish January 23, 2017, as a refund effective date. The complaint includes return on equity analysis that purports to establish that the range of reasonable return on equity for System Energy is between 8.37% and 8.67%. System Energy answered the complaint in February 2017 and disputes that a return on equity of 8.37% to 8.67% is just and reasonable. The City of New Orleans filed comments in February 2017 supporting the complaint. System Energy is recording a provision against revenue for the potential outcome of this proceeding. Action by the FERC is pending.

The fuel reconciliation settlement was approved by the PUCT in March 2017. Retail Rate Proceedings See Note 2 to the financial statements in the Form 10-K for detailed information regarding retail rate proceedings involving the Utility operating companies. The following are updates to that information. Filings with the APSC 2016 Formula Rate Plan Filing As discussed in the Form 10-K, Entergy Arkansas is required to make a supplemental filing supporting the recovery of certain nuclear costs. In April 2017, Entergy Arkansas filed a motion consented to by all parties requesting that it be permitted to submit its supplemental filing in conjunction with its 2017 formula rate plan filing, scheduled to be made in July 2017. Advanced Metering Infrastructure (AMI) Filing As discussed in the Form 10-K, in September 2016, Entergy Arkansas filed an application seeking a finding from the APSC that Entergy Arkansas’s deployment of advanced metering infrastructure is in the public interest. This matter is pending before the APSC.

The LPSC’s review is pending. Also, in November 2016, Entergy Louisiana filed with the LPSC a request to extend the MISO cost recovery mechanism rider provision of its formula rate plan. A procedural schedule was established, including a hearing in July 2017. In March 2017 the LPSC staff submitted direct testimony generally supportive of a one-year extension of the MISO cost recovery mechanism and the intervenor in the proceeding does not oppose an extension for this period of time. Waterford 3 Replacement Steam Generator Project See Note 2 to the financial statements in the Form 10-K for discussion of the Waterford 3 replacement steam generator project prudence review proceeding. The refund to customers of approximately $71 million as a result of the settlement approved by the LPSC was made to customers in January 2017. Union Power Station As a term of the LPSC-approved settlement authorizing the purchase of Power Blocks 3 and 4 of the Union Power Station, Entergy Louisiana agreed to make a filing with the LPSC to review its decisions to deactivate Ninemile 3 and Willow Glen 2 and 4 and its decision to retire Little Gypsy 1. In January 2016, Entergy Louisiana made its compliance filing with the LPSC. Entergy Louisiana, LPSC staff, and intervenors participated in a technical conference in March 2016 where Entergy Louisiana presented information on its deactivation/retirement decisions for these four units in addition to information on the current deactivation decisions for the ten-year planning horizon. Parties have requested further proceedings on the prudence of the decision to deactivate Willow Glen 2 and 4. No party contests the prudence of the decision to deactivate Willow Glen 2 and 4 or suggests reactivation of these units; however, issues have been raised related to Entergy Louisiana’s decision to retire Willow Glen 2 and 4, as opposed to temporarily suspending those units. This matter is pending before an ALJ, with an evidentiary hearing scheduled to commence in July 2017. The ALJ recently dismissed claims of an industrial user regarding a proposed process for future deactivation because the LPSC initiated a generic rulemaking to consider whether the LPSC should review deactivation decisions prior to implementation. Retail Rates - Gas 2016 Rate Stabilization Plan Filing In January 2017, Entergy Louisiana filed with the LPSC its gas rate stabilization plan for the test year ended September 30, 2016. The filing of the evaluation report for test year 2016 reflected an earned return on common equity of 6.37%. As part of the original filing, pursuant to the extraordinary cost provision of the rate stabilization plan, Entergy Louisiana sought to recover approximately $1.5 million in deferred operation and maintenance expenses incurred to restore service and repair damage resulting from flooding and widespread rainfall in southeast Louisiana that occurred in August 2016. Entergy Louisiana requested to recover the prudently incurred August 2016 storm restoration costs over ten years, outside of the rate stabilization plan sharing provisions. As a result, Entergy Louisiana’s filing sought an annual increase in revenue of $1.4 million. Following review of the filing, except for the proposed extraordinary cost recovery, the LPSC staff confirmed Entergy Louisiana’s filing was consistent with the principles and requirements of the rate stabilization plan. The extraordinary cost recovery request associated with the 2016 flood-related deferred operation and maintenance expenses incurred for gas operations was removed from the rate stabilization plan pending LPSC consideration in a separate docket. In April 2017 the LPSC approved a joint report of proceedings and Entergy Louisiana submitted a revised evaluation report reflecting a $1.2 million annual increase in revenue with rates implemented with the first billing cycle of May 2017. Advanced Metering Infrastructure (AMI) Filing As discussed in the Form 10-K, in November 2016, Entergy Louisiana filed an application seeking a finding from the LPSC that Entergy Louisiana’s deployment of advanced electric and gas metering infrastructure is in the public interest.

The filing is currently subject to MPSC review. Advanced Metering Infrastructure (AMI) Filing As discussed in the Form 10-K, in November 2016, Entergy Mississippi filed an application seeking a finding from the MPSC that Entergy Mississippi’s deployment of advanced metering infrastructure is in the public interest. In May 2017 the Mississippi Public Utilities Staff and Entergy Mississippi entered into and filed a joint stipulation supporting Entergy Mississippi’s filing, and the MPSC issued an order approving the filing without any material changes, finding that Entergy Mississippi’s deployment of AMI is in the public interest and granting a certificate of public convenience and necessity. The MPSC order also confirmed that Entergy Mississippi shall continue to include in rate base the remaining book value of existing meters that will be retired as part of the AMI deployment and also to depreciate those assets using current depreciation rates. Filings with the City Council Retail Rates As discussed in the Form 10-K, in February 2017, Entergy New Orleans filed a proposed implementation plan for the Energy Smart program from April 2017 through March 2020. As part of the proposal, Entergy New Orleans requested that the City Council identify its desired level of funding for the program during this time period and approve a cost recovery mechanism. In April 2017 the City Council approved an implementation plan for the Energy Smart program from April 2017 through December 2019. The City Council directed that the $11.8 million balance reported for Energy Smart funds be used to continue funding the program for Entergy New Orleans’s legacy customers and that the Energy Smart Algiers program continue to be funded through the Algiers fuel adjustment clause, until additional customer funding is required for the legacy customers. The City Council ordered Entergy New Orleans to submit a supplemental and amended implementation plan for program years 8 and 9 of the Energy Smart program (January 2018 through December 2019) in October 2017. Following that filing, the City Council will determine a specific cost recovery mechanism for the program for both legacy and Algiers customers. The City Council will not permit Entergy New Orleans to recover lost contribution to fixed costs for program years 7, 8, or 9 of the Energy Smart program. Internal Restructuring As discussed in the Form 10-K, in July 2016, Entergy New Orleans filed an application with the City Council seeking authorization to undertake a restructuring that would result in the transfer of substantially all of the assets and operations of Entergy New Orleans to a new entity, which would ultimately be owned by an existing Entergy subsidiary holding company. In May 2017 the City Council adopted a resolution approving the proposed internal restructuring pursuant to an agreement in principle with the City Council advisors and certain intervenors. Pursuant to the agreement in principle, Entergy New Orleans will credit retail customers $10 million in 2017, $1.4 million in the first quarter of the year after the transaction closes, and $117,500 each month in the second year after the transaction closes until such time as new base rates go into effect as a result of the anticipated 2018 base rate case. Additionally, if the FERC approves the transaction prior to December 31, 2018, Entergy New Orleans will credit retail customers $5 million in each of the years 2018, 2019, and 2020. Advanced Metering Infrastructure (AMI) Filing As discussed in the Form 10-K, in October 2016, Entergy New Orleans filed an application seeking a finding from the City Council that Entergy New Orleans’s deployment of advanced electric and gas metering infrastructure is in the public interest.

Filings with the PUCT Other Filings In September 2016, Entergy Texas filed with the PUCT a request to amend its transmission cost recovery factor (TCRF) rider. The proposed amended TCRF rider is designed to collect approximately $29.5 million annually from Entergy Texas’s retail customers.
