Variable Interest Entities [Abstract]
VARIABLE INTEREST ENTITIES	VARIABLE INTEREST ENTITIES FET and its subsidiaries perform qualitative analyses to determine whether a variable interest qualifies FET or its subsidiaries as the primary beneficiary (a controlling financial interest) of a VIE. An enterprise has a controlling financial interest if it has both: (i) the power to direct the activities of a VIE that most significantly impact the entity's economic performance; and (ii) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. FET consolidates a VIE when it is determined that it is the primary beneficiary. Consolidated VIEs •MAIT - At its inception, MAIT issued Class A membership interests to FET and Class B membership interests to FE PA predecessors (PN and ME). The Class A interests represent the functional equivalent of managing interests, providing FET with the power to direct the activities that most significantly impact MAIT's performance. The Class B interests represent the functional equivalent of economic interest conveying no kick-out or participating rights over the Class A membership interests. Management concluded that MAIT is a VIE and that FET is the primary beneficiary because FET has exposure to the economics of MAIT and the power to direct the significant activities of MAIT through its ownership of the Class A membership interests. On January 1, 2024, FE PA, as successor-in-interest to PN and ME, transferred their respective Class B equity interests of MAIT to FE. FE ultimately contributed the MAIT Class B equity interests to FET in exchange for a special purpose membership interest in FET. The transfer of the Class B membership interests to FET during the first quarter of 2024 had no impact on MAIT's classification as a VIE. FET has not provided any guarantees or other credit support for the benefit of MAIT or MAIT's creditors. Unconsolidated VIEs •Valley Link - Investment balances as of September 30, 2026, and earnings during the first nine months of 2026 related to Valley Link were immaterial. See Note 1., “Organization and Basis of Presentation – Investments," and Note 7., “Commitments, Guarantees and Contingencies,” of the Notes to Consolidated Financial Statements for additional information related to Valley Link. •Grid Growth - There were no investment balances as of September 30, 2026, and no earnings were recognized during the first nine months of 2026 related to Grid Growth. See Note 1., “Organization and Basis of Presentation – Investments," of the Notes to Consolidated Financial Statements for additional information related to Grid Growth.
