(d)
Evaluation of request
(1)
In general
The evaluation of a request for basic access service for energy-only delivery shall—
(A)
consist of only the set of steady-state (thermal and voltage), short-circuit, stability analysis, and facilities studies, as provided for under section 35.28 of title 18, Code of Federal Regulations (or a successor regulation) (and the corresponding generator interconnection procedures), that are necessary to determine whether additional transmission facilities or upgrades to existing transmission facilities are needed to reliably interconnect a new or modified generating facility to the transmission system of the applicable Regional Transmission Organization or Independent System Operator in compliance with applicable reliability standards; and
(B)
reflect the expected operating characteristics of the generating facility, including any operating limits, curtailment provisions, or modifications to the generating facility proposed or agreed to by the interconnection customer.
(2)
Findings
(A)
In general
An evaluation under paragraph (1) shall identify—
(i)
the maximum level of injection at the point of interconnection that can be accommodated without additional transmission facilities or upgrades to existing transmission facilities;
(ii)
any additional transmission facilities or upgrades to existing transmission facilities necessary to accommodate injection above the level identified under clause (i), up to the level requested by the interconnection customer; and
(iii)
each constraint assumed under paragraph (4) to be managed through operational measures.
(B)
Election
An interconnection customer may elect to receive basic access service for energy-only delivery—
(i)
at the level identified under subparagraph (A)(i) without additional transmission facilities or upgrades; or
(ii)
at a higher approved level, subject to subsection (f)(2).
(3)
Deliverability limitation
(A)
In general
The evaluation described in paragraph (1) shall not be used to identify facilities or upgrades, or require the construction of facilities, for the purpose of—
(i)
enabling the deliverability of electric energy from the generating facility to load, market, or transmission service points; or
(ii)
ensuring that the generating facility will not experience congestion-related curtailment.
(B)
Incidental effects on deliverability or congestion-related curtailment
Nothing in subparagraph (A) prohibits the identification of facilities or upgrades that—
(i)
are necessary to reliably interconnect a generating facility in compliance with applicable reliability standards; and
(ii)
may have incidental effects on deliverability or congestion-related curtailment.
(4)
Operationally manageable constraints
An evaluation under paragraph (1)—
(A)
shall assume that a constraint identified in the evaluation will be managed through operational measures, including redispatch, curtailment, operating limits, and remedial action schemes; and
(B)
may identify facilities or upgrades for a constraint only to the extent that operational measures cannot maintain compliance with applicable reliability standards.
(5)
Study timelines
The applicable Regional Transmission Organization or Independent System Operator shall establish procedures to complete the evaluation of a request for basic access service for energy-only delivery not later than 1 year after the date on which the request is submitted.
(e)
Interconnection rights
Basic access service for energy-only delivery shall be subject to operating limits, curtailment provisions, and the terms of the applicable interconnection agreement, so long as those limits, provisions, and terms are not unjust, unreasonable, or unduly discriminatory or preferential.
(f)
Conditions of service
(1)
Congestion-related curtailment
Basic access service for energy-only delivery may be subject to congestion-related curtailment, including curtailment associated with constraints identified in the evaluation under subsection (d)(1).
