Commitments and Contingencies Disclosure [Text Block]	COMMITMENTS AND CONTINGENCIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Entergy and the Registrant Subsidiaries are involved in a number of legal, regulatory, and tax proceedings before various courts, regulatory authorities, and governmental agencies in the ordinary course of business. While management is unable to predict with certainty the outcome of such proceedings, management does not believe that the ultimate resolution of these matters will have a material adverse effect on Entergy’s results of operations, cash flows, or financial condition, except as otherwise discussed in the Form 10-K or in this report. Entergy discusses regulatory proceedings in Note 2 to the financial statements in the Form 10-K and herein and discusses tax proceedings in Note 3 to the financial statements in the Form 10-K and Note 10 to the financial statements herein. Vidalia Purchased Power Agreement See Note 8 to the financial statements in the Form 10-K for information on Entergy Louisiana’s Vidalia purchased power agreement. Spent Nuclear Fuel Litigation See Note 8 to the financial statements in the Form 10-K for information on Entergy’s spent nuclear fuel litigation. The following is an update to that discussion. As discussed in the Form 10-K, in October 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $7 million in favor of Holtec Palisades, LLC (previously Entergy Nuclear Palisades) and against the DOE in the final round Palisades damages case. Holtec, as the current owner, received payment from the U.S. Treasury in March 2025 and subsequently transferred the $7 million judgment to Entergy. The effect in 2024 of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). The damages awarded included $4 million related to costs previously recorded as plant and $3 million related to costs previously recorded as other operation and maintenance expenses. Nuclear Insurance See Note 8 to the financial statements in the Form 10-K for information on nuclear liability and property insurance associated with Entergy’s nuclear power plants. Non-Nuclear Property Insurance See Note 8 to the financial statements in the Form 10-K for information on Entergy’s non-nuclear property insurance program. Employment and Labor-related Proceedings See Note 8 to the financial statements in the Form 10-K for information on Entergy’s employment and labor-related proceedings. Asbestos Litigation (Entergy Arkansas, Entergy Louisiana, Entergy New Orleans, and Entergy Texas) See Note 8 to the financial statements in the Form 10-K for information regarding asbestos litigation. Grand Gulf-Related Agreements See Note 8 to the financial statements in the Form 10-K for information regarding Grand Gulf-related agreements, including the Unit Power Sales Agreement, the Availability Agreement, and the Reallocation Agreement. The following is an update to that discussion. As discussed in the Form 10-K, System Energy historically sold all of its share of capacity and energy from Grand Gulf to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans in accordance with specified percentages (Entergy Arkansas - 36%, Entergy Louisiana - 14%, Entergy Mississippi - 33%, and Entergy New Orleans - 17%) as ordered by the FERC under the Unit Power Sales Agreement. In August 2024 the LPSC approved a settlement with Entergy Louisiana to globally resolve all of the LPSC’s actual and potential claims in multiple docketed proceedings pending before the FERC and with System Energy’s past implementation of the Unit Power Sales Agreement. The settlement was approved by the FERC in November 2024. The terms of the settlement included an agreement that Entergy Louisiana would divest to Entergy Mississippi its 14% share of capacity and energy from Grand Gulf under the Unit Power Sales Agreement and its 2.43% share of capacity and energy from Entergy Arkansas under the MSS-4 replacement tariff. This divestiture was being effectuated initially through Entergy Mississippi’s purchases from Entergy Louisiana pursuant to a bridge PPA governed by the MSS-4 replacement tariff (bridge PPA). In September 2024, Entergy Mississippi filed a notice of intent with the MPSC that related to and sought approval of the divestiture. The bridge PPA to effectuate this divestiture was approved by the FERC in November 2024. The MPSC approved the bridge PPA, effective as of January 1, 2025. Under the divestiture, Entergy Mississippi also assumed any and all of Entergy Louisiana’s rights and obligations under the Availability Agreement and agreed to hold Entergy Louisiana harmless with respect thereto, as of January 1, 2025. Effective October 1, 2025, System Energy began selling all of its share of capacity and energy from Grand Gulf to Entergy Arkansas, Entergy Mississippi, and Entergy New Orleans in accordance with specified percentages (Entergy Arkansas - 24.2%, Entergy Mississippi - 56.4%, and Entergy New Orleans - 19.4%) as approved by the FERC under an amended Unit Power Sales Agreement. The amended Unit Power Sales Agreement removed Entergy Louisiana from the entitlement to purchase power from Grand Gulf and thus on October 1, 2025, the bridge PPA between Entergy Louisiana and Entergy Mississippi terminated. In addition, effective October 1, 2025, System Energy, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans terminated the Availability Agreement, and, immediately thereafter, System Energy, Entergy Arkansas, Entergy Mississippi, and Entergy New Orleans entered into a new Availability Agreement with allocation percentages conforming to their entitlement percentages under the amended Unit Power Sales Agreement. See Note 2 to the financial statements herein and in the Form 10-K for discussion of the System Energy settlement with the LPSC. Exclusivity Agreement with Major Vendor Entergy entered into an exclusivity agreement with a major vendor to manufacture power island equipment (PIE) and combustion turbines (CT) for combustion turbine generator set frames larger than 400 MWs. The agreement guarantees Entergy one manufacturing slot per quarter for the shorter of a five-year period or until Entergy fulfills its minimum commitment. The agreement was amended in third quarter 2025, updating the minimum order of 15 sets of PIE and two CTs to a minimum order of 21 sets of PIE and two CTs during that time period. The commitments are fully transferable to any of the Utility operating companies. Cancellation or failure to purchase the minimum commitment amounts will result in a charge. If any of the Utility operating companies purchases any CTs within the scope of the agreement from another supplier (except as permitted under the agreement), then the vendor has the right to terminate all or a portion of the agreement. In the event of such termination, the Utility operating company would then be obligated to pay 50% of the CT base price for each PIE or CT not yet ordered. The agreement does not establish final pricing and delivery dates of purchases that will go towards meeting the commitments under the agreement. Such terms shall be agreed to in separate agreements.

Commitments and Contingencies Disclosure [Text Block]	COMMITMENTS AND CONTINGENCIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Entergy and the Registrant Subsidiaries are involved in a number of legal, regulatory, and tax proceedings before various courts, regulatory authorities, and governmental agencies in the ordinary course of business. While management is unable to predict with certainty the outcome of such proceedings, management does not believe that the ultimate resolution of these matters will have a material adverse effect on Entergy’s results of operations, cash flows, or financial condition, except as otherwise discussed in the Form 10-K or in this report. Entergy discusses regulatory proceedings in Note 2 to the financial statements in the Form 10-K and herein and discusses tax proceedings in Note 3 to the financial statements in the Form 10-K and Note 10 to the financial statements herein. Vidalia Purchased Power Agreement See Note 8 to the financial statements in the Form 10-K for information on Entergy Louisiana’s Vidalia purchased power agreement. Spent Nuclear Fuel Litigation See Note 8 to the financial statements in the Form 10-K for information on Entergy’s spent nuclear fuel litigation. The following is an update to that discussion. As discussed in the Form 10-K, in October 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $7 million in favor of Holtec Palisades, LLC (previously Entergy Nuclear Palisades) and against the DOE in the final round Palisades damages case. Holtec, as the current owner, received payment from the U.S. Treasury in March 2025 and subsequently transferred the $7 million judgment to Entergy. The effect in 2024 of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). The damages awarded included $4 million related to costs previously recorded as plant and $3 million related to costs previously recorded as other operation and maintenance expenses. Nuclear Insurance See Note 8 to the financial statements in the Form 10-K for information on nuclear liability and property insurance associated with Entergy’s nuclear power plants. Non-Nuclear Property Insurance See Note 8 to the financial statements in the Form 10-K for information on Entergy’s non-nuclear property insurance program.

Asbestos Litigation (Entergy Arkansas, Entergy Louisiana, Entergy New Orleans, and Entergy Texas) See Note 8 to the financial statements in the Form 10-K for information regarding asbestos litigation. Grand Gulf-Related Agreements See Note 8 to the financial statements in the Form 10-K for information regarding Grand Gulf-related agreements, including the Unit Power Sales Agreement, the Availability Agreement, and the Reallocation Agreement. The following is an update to that discussion. As discussed in the Form 10-K, System Energy historically sold all of its share of capacity and energy from Grand Gulf to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans in accordance with specified percentages (Entergy Arkansas - 36%, Entergy Louisiana - 14%, Entergy Mississippi - 33%, and Entergy New Orleans - 17%) as ordered by the FERC under the Unit Power Sales Agreement. In August 2024 the LPSC approved a settlement with Entergy Louisiana to globally resolve all of the LPSC’s actual and potential claims in multiple docketed proceedings pending before the FERC and with System Energy’s past implementation of the Unit Power Sales Agreement. The settlement was approved by the FERC in November 2024. The terms of the settlement included an agreement that Entergy Louisiana would divest to Entergy Mississippi its 14% share of capacity and energy from Grand Gulf under the Unit Power Sales Agreement and its 2.43% share of capacity and energy from Entergy Arkansas under the MSS-4 replacement tariff. This divestiture was being effectuated initially through Entergy Mississippi’s purchases from Entergy Louisiana pursuant to a bridge PPA governed by the MSS-4 replacement tariff (bridge PPA). In September 2024, Entergy Mississippi filed a notice of intent with the MPSC that related to and sought approval of the divestiture. The bridge PPA to effectuate this divestiture was approved by the FERC in November 2024. The MPSC approved the bridge PPA, effective as of January 1, 2025. Under the divestiture, Entergy Mississippi also assumed any and all of Entergy Louisiana’s rights and obligations under the Availability Agreement and agreed to hold Entergy Louisiana harmless with respect thereto, as of January 1, 2025. Effective October 1, 2025, System Energy began selling all of its share of capacity and energy from Grand Gulf to Entergy Arkansas, Entergy Mississippi, and Entergy New Orleans in accordance with specified percentages (Entergy Arkansas - 24.2%, Entergy Mississippi - 56.4%, and Entergy New Orleans - 19.4%) as approved by the FERC under an amended Unit Power Sales Agreement. The amended Unit Power Sales Agreement removed Entergy Louisiana from the entitlement to purchase power from Grand Gulf and thus on October 1, 2025, the bridge PPA between Entergy Louisiana and Entergy Mississippi terminated. In addition, effective October 1, 2025, System Energy, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans terminated the Availability Agreement, and, immediately thereafter, System Energy, Entergy Arkansas, Entergy Mississippi, and Entergy New Orleans entered into a new Availability Agreement with allocation percentages conforming to their entitlement percentages under the amended Unit Power Sales Agreement. See Note 2 to the financial statements herein and in the Form 10-K for discussion of the System Energy settlement with the LPSC. Exclusivity Agreement with Major Vendor Entergy entered into an exclusivity agreement with a major vendor to manufacture power island equipment (PIE) and combustion turbines (CT) for combustion turbine generator set frames larger than 400 MWs. The agreement guarantees Entergy one manufacturing slot per quarter for the shorter of a five-year period or until Entergy fulfills its minimum commitment. The agreement was amended in third quarter 2025, updating the minimum order of 15 sets of PIE and two CTs to a minimum order of 21 sets of PIE and two CTs during that time period. The commitments are fully transferable to any of the Utility operating companies. Cancellation or failure to purchase the minimum commitment amounts will result in a charge. If any of the Utility operating companies purchases any CTs within the scope of the agreement from another supplier (except as permitted under the agreement), then the vendor has the right to terminate all or a portion of the agreement. In the event of such termination, the Utility operating company would then be obligated to pay 50% of the CT base price for each PIE or CT not yet ordered. The agreement does not establish final pricing and delivery dates of purchases that will go towards meeting the commitments under the agreement. Such terms shall be agreed to in separate agreements.

The agreement does not establish final pricing and delivery dates of purchases that will go towards meeting the commitments under the agreement. Such terms shall be agreed to in separate agreements.

COMMITMENTS AND CONTINGENCIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy)

Entergy and the Registrant Subsidiaries are involved in a number of legal, regulatory, and tax proceedings before various courts, regulatory authorities, and governmental agencies in the ordinary course of business. While management is unable to predict with certainty the outcome of such proceedings, management does not believe that the ultimate resolution of these matters will have a material adverse effect on Entergy’s results of operations, cash flows, or financial condition, except as otherwise discussed in the Form 10-K or in this report. Entergy discusses regulatory proceedings in Note 2 to the financial statements in the Form 10-K and herein and discusses tax proceedings in Note 3 to the financial statements in the Form 10-K and Note 10 to the financial statements herein.

Grand Gulf-Related Agreements

See Note 8 to the financial statements in the Form 10-K for information regarding Grand Gulf-related agreements, including the Unit Power Sales Agreement, the Availability Agreement, and the Reallocation Agreement. The following is an update to that discussion.

As discussed in the Form 10-K, System Energy historically sold all of its share of capacity and energy from Grand Gulf to Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans in accordance with specified percentages (Entergy Arkansas - 36%, Entergy Louisiana - 14%, Entergy Mississippi - 33%, and Entergy New Orleans - 17%) as ordered by the FERC under the Unit Power Sales Agreement. In August 2024 the LPSC approved a settlement with Entergy Louisiana to globally resolve all of the LPSC’s actual and potential claims in multiple docketed proceedings pending before the FERC and with System Energy’s past implementation of the Unit Power Sales Agreement. The settlement was approved by the FERC in November 2024. The terms of the settlement included an agreement that Entergy Louisiana would divest to Entergy Mississippi its 14% share of capacity and energy from Grand Gulf under the Unit Power Sales Agreement and its 2.43% share of capacity and energy from Entergy Arkansas under the MSS-4 replacement tariff. This divestiture was being effectuated initially through Entergy Mississippi’s purchases from Entergy Louisiana pursuant to a bridge PPA governed by the MSS-4 replacement tariff (bridge PPA). In September 2024, Entergy Mississippi filed a notice of intent with the MPSC that related to and sought approval of the divestiture. The bridge PPA to effectuate this divestiture was approved by the FERC in November 2024. The MPSC approved the bridge PPA, effective as of January 1, 2025. Under the divestiture, Entergy Mississippi also assumed any and all of Entergy Louisiana’s rights and obligations under the Availability Agreement and agreed to hold Entergy Louisiana harmless with respect thereto, as of January 1, 2025.

Effective October 1, 2025, System Energy began selling all of its share of capacity and energy from Grand Gulf to Entergy Arkansas, Entergy Mississippi, and Entergy New Orleans in accordance with specified percentages (Entergy Arkansas - 24.2%, Entergy Mississippi - 56.4%, and Entergy New Orleans - 19.4%) as approved by the FERC under an amended Unit Power Sales Agreement. The amended Unit Power Sales Agreement removed Entergy Louisiana from the entitlement to purchase power from Grand Gulf and thus on October 1, 2025, the bridge PPA between Entergy Louisiana and Entergy Mississippi terminated. In addition, effective October 1, 2025, System Energy, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans terminated the Availability Agreement, and, immediately thereafter, System Energy, Entergy Arkansas, Entergy Mississippi, and Entergy New Orleans entered into a new Availability Agreement with allocation percentages conforming to their entitlement percentages under the amended Unit Power Sales Agreement. See Note 2 to the financial statements herein and in the Form 10-K for discussion of the System Energy settlement with the LPSC.

Exclusivity Agreement with Major Vendor

Entergy entered into an exclusivity agreement with a major vendor to manufacture power island equipment (PIE) and combustion turbines (CT) for combustion turbine generator set frames larger than 400 MWs. The agreement guarantees Entergy one manufacturing slot per quarter for the shorter of a five-year period or until Entergy fulfills its minimum commitment. The agreement was amended in third quarter 2025, updating the minimum order of 15 sets of PIE and two CTs to a minimum order of 21 sets of PIE and two CTs during that time period. The commitments are fully transferable to any of the Utility operating companies. Cancellation or failure to purchase the minimum commitment amounts will result in a charge.

If any of the Utility operating companies purchases any CTs within the scope of the agreement from another supplier (except as permitted under the agreement), then the vendor has the right to terminate all or a portion of the agreement. In the event of such termination, the Utility operating company would then be obligated to pay 50% of the CT base price for each PIE or CT not yet ordered. The agreement does not establish final pricing and delivery dates of purchases that will go towards meeting the commitments under the agreement. Such terms shall be agreed to in separate agreements.
