| (E) After the completion and energization of the initial
interconnection, the responsibility for costs incurred by a TSP for
new or upgraded interconnection facilities due to modifications or
expansions made by the interconnected transmission-level generator
will be borne in accordance with this subparagraph.
(i) For the ten calendar years following the date of
energization for the initial interconnection of the transmission-level
generator, and to the extent that the costs of the new or upgraded
interconnection facilities needed due to modifications made by the
transmission-level generator exceed the remainder of the allowance
calculated under paragraph (3) of this subsection, the current owner
of the transmission-level generator that is listed in the new or amended
SGIA is responsible for the interconnection costs incurred by the
TSP, where:
(I) the allowance is the amount that was in effect
on the date the notice to proceed with the initial interconnection
was issued in accordance with paragraph (3) of this subsection and
the executed SGIA; and
(II) the remainder is the difference between the allowance
described under subclause (I) of this clause and the actual costs
that a TSP incurred to construct, design, and upgrade interconnection
facilities to initially interconnect the transmission-level generator.
The remainder will be adjusted by the TSP in accordance with the methodology
in subparagraph (A)(ii) of this paragraph.
(ii) After ten calendar years from the date of energization
for the initial interconnection, the transmission-level generator
is eligible for a new allowance determined in accordance with paragraph
(3)(A) of this subsection for the costs of new or upgraded interconnection
facilities necessary to accommodate modifications made by the transmission-level
generator at the same point of interconnection.
(F) Beginning on or around May 1, 2029, and at least
every five calendar years thereafter, the commission will open a project
and request comments on whether the allowance or annual allowance
adjustment methodology described in paragraph (3)(A) of this subsection
should be modified. If the commission determines the allowance or
the annual allowance adjustment methodology should be adjusted, the
commission will initiate a rulemaking proceeding.
(g) Curtailment of service. In an emergency situation,
as determined by ERCOT and at its direction, a TSP may interrupt transmission
service on a non-discriminatory basis, if necessary, to preserve the
stability of the transmission network and service to customers. Such
curtailments must be carried out in accordance with §25.200 of
this title (relating to Load Shedding, Curtailments, and Redispatch)
and in accordance with ERCOT protocols.
(h) Filing of contracts. An electric utility must file
with the commission each new, and all amendments to, interconnection
agreements within 30 days of execution, including a cover letter explaining
any deviations from the commission-approved SGIA. An interconnection
agreement is subject to commission review and approval upon request
by any party to the agreement. Appropriate portions of the filings
may be filed confidentially and be subject to provisions of confidentiality
to protect competitively sensitive commercial or financial information.
(i) Transmission-level generator interconnection costs
report. ERCOT must, in consultation with commission staff, include
as part of the ERCOT Generation Interconnection Status report or any
successor report the generation interconnection costs for each new
transmission-level generator interconnected in each calendar month
based on date of energization, including the total cost of the interconnection,
any CIAC paid by the transmission-level generator, and any above-allowance
costs incurred by the transmission-level generator.
(1) Beginning in January 2026, within 90 calendar days
from the end of each calendar month the TSP must provide to ERCOT
the information described in this subsection for each new transmission-level
generator interconnection to the TSP's system in that calendar month.
(2) Beginning in April 2027 and every calendar year
thereafter, ERCOT will publish the information described in this subsection
in a separate report for each new transmission-level generator interconnection
to the ERCOT transmission system in the prior calendar year. ERCOT
will, at a minimum, provide the information described in this subsection
and total amounts for the prior calendar year.
