Upon the later of the final date set forth in the applicable transitional funding order for the imposition and collection of instrument funding charges or the repayment in full of any grantee instruments or transitional funding instruments, as applicable, authorized in such order, the authority to impose and collect the related instrument funding charges shall cease and the relevant electric utility shall be entitled to file tariffs revoking any deductions from base rates, transition charges or other rates for tariffed services which were granted in connection with such instrument funding charges pursuant to subsection (j) of Section 18-104 or subsection (k) of Section 18-104. The Commission shall have no authority to review such tariffs except to determine that the rates and charges resulting from such revocation do not exceed the applicable base rates, transition charges, or other rates for tariffed services which would otherwise have been in effect at the time of such revocation had no instrument funding charges ever been deducted therefrom.
