New Mexico Administrative Code › Title 17 - PUBLIC UTILITIES AND UTILITY SERVICES › Chapter 9 - ELECTRIC SERVICES › Part 568 - INTERCONNECTION OF GENERATING FACILITIES WITH A NAMEPLATE RATING UP TO AND INCLUDING 10 MW CONNECTING TO A UTILITY SYSTEM › Section 17.9.568.16 - FAST TRACK PROCESS

Current through Register Vol. 35, No. 13, July 16, 2024
A.
Application:
An interconnection customer must submit an
				interconnection application, pursuant to Subsection B of
				17.9.568.13 NMAC, using the
				standard interconnection application form provided in Appendix 1B, which may be
				sent electronically to a recipient designated by the utility. The application
				fee specified in Subsection A of
				17.9.568.23 NMAC shall be
				submitted along with the interconnection application.
B.
Fast track screening:
The
				utility shall evaluate the interconnection application using the following fast
				track initial review screens.
(1)
Screen
				1
: For interconnection of a proposed generating facility to the load
				side of network protectors, the proposed generating facility must utilize a
				certified inverter-based equipment package and its nameplate rating, together
				with the nameplate rating of the aggregated other inverter-based generation,
				shall not exceed fifty percent of the secondary network's relevant minimum
				load.
(2)
Screen 2
:
				Until December 31, 2023, for interconnection of a proposed generating facility
				to a radial distribution circuit, the aggregate export capacity of the
				generating facilities connected to the distribution circuit, including the
				proposed generating facility, may not exceed one hundred percent of the
				relevant minimum load (or fifteen percent of maximum load if minimum load data
				is unavailable) normally supplied by the distribution circuit. After December
				31, 2023, for interconnection of a proposed generating facility to a radial
				distribution circuit, the aggregate export capacity of the generating
				facilities connected to the distribution circuit, including the proposed
				generating facility, may not exceed one hundred percent of the relevant minimum
				load normally supplied by the distribution circuit.
(3)
Screen 3
: For
				interconnection of a proposed generating facility that can introduce
				inadvertent export, where the nameplate rating minus the export capacity is
				greater than 250 kW, the following inadvertent export screen limit is required.
				With a power change equal to the nameplate rating minus the export capacity,
				the change in voltage at the point on the medium voltage (primary) level
				nearest the point of interconnection does not exceed three percent. Voltage
				change will be estimated applying the following formula:

Screen 4
: If the proposed generating facility is to be
				interconnected on a single-phase shared secondary, the aggregate export
				capacity on the shared secondary, including the proposed generating facility,
				shall not exceed sixty-five percent of the transformer nameplate power
				rating.
(5)
Screen 5
:
				If the proposed generating facility is single-phase and is to be interconnected
				on a center tap neutral of a 120/240 volt service, its addition shall not
				create an imbalance between the two sides of the 240 volt service of more than
				twenty percent of the nameplate rating of the service transformer.
(6)
Screen 6
: The starting
				voltage dip shall be less than five percent and the flicker requirements of
				IEEE 1547TT-2018 must be met. This screen only applies to generating facilities
				that start by motoring the generator(s).
(7)
Screen 7
: When measured at
				the primary side (high side) of a dedicated distribution transformer serving a
				generating facility, the sum of the short circuit current contribution ratios
				of all generating facilities connected to utility's distribution system circuit
				that serves the generating facility must be less than or equal to
				0.1.
(8)
Screen 8
: The
				generating facility, aggregated with other generation on the distribution
				circuit, will not cause any distribution protective devices and equipment
				(including but not limited to substation breakers, fuse cutouts, and line
				reclosers), or utility customer equipment on the system, to exceed ninety
				percent of the short circuit interrupting capability; nor is the
				interconnection proposed for a circuit that already exceeds ninety percent of
				the short circuit interrupting capability.
(9)
Screen 9
: The generating
				facility complies with the applicable type of interconnection, based on the
				table below. This screen includes a review of the type of electrical service
				provided to the interconnecting customer, including line configuration and the
				transformer connection to limit the potential for creating over-voltages on the
				utility's electric power system due to a loss of ground during the operating
				time of any anti-islanding function.
