Amend CSSB 3 (house committee report) as follows:
(1)  On page 13, line 25, strike "Subsection (e) and adding Subsections (f)," and substitute "Subsections (d) and (e) and adding Subsections (d-1), (f),".
(2)  On page 13, between lines 26 and 27, insert the following:
(d)  The commission shall price wholesale transmission services within ERCOT based on the postage stamp method of pricing under which a transmission-owning utility's rate is based on the ERCOT utilities' combined annual costs of transmission, other than costs that exceed the allowance described in Subsection (d-1), divided by the total demand placed on the combined transmission systems of all such transmission-owning utilities within a power region. An electric utility subject to the freeze period imposed by Section 39.052 may treat transmission costs in excess of transmission revenues during the freeze period as an expense for purposes of determining annual costs in the annual report filed under Section 39.257. Notwithstanding Section 36.201, the commission may approve wholesale rates that may be periodically adjusted to ensure timely recovery of transmission investment. Notwithstanding Section 36.054(a), if the commission determines that conditions warrant the action, the commission may authorize the inclusion of construction work in progress in the rate base for transmission investment required by the commission under Section 39.203(e).
(d-1)  The commission by rule shall establish a reasonable allowance for capital costs incurred to interconnect generation resources and electric energy storage resources described by Section 35.152(a) with the ERCOT transmission system, which must include the costs of the direct interconnection of the generator to the system and upgrades directly caused by the interconnection. Any costs that exceed the allowance must be borne directly by the generation resource or electric energy storage resource receiving interconnection service through the facilities.
