Current through Vol. 24-12, July 15, 2024
Rule 50.
(1) An
				  electric utility shall list in its interconnection procedures the supplemental
				  review screens specified in subrule (6) of this rule. An electric utility may
				  add additional details to each of these screens in the interconnection
				  procedures.
(2) An electric utility
				  may include additional supplemental review screens in its interconnection
				  procedures. In its application requesting approval of interconnection
				  procedures, the electric utility shall provide a detailed technical rationale
				  for the inclusion of each supplemental review screen. If an additional screen
				  negates or undermines any of the supplemental review screens specified in
				  subrule (6) of this rule, the rationale must include an explanation of the
				  technical justification for the additional screen.
(3) An electric utility may waive application
				  of 1, some, or all of the supplemental review screens.
(4) To receive a supplemental review, an
				  applicant shall submit payment of the supplemental review fee within 20
				  business days of agreeing to a supplemental review. If payment of the fee has
				  not been received by the electric utility within 25 business days, the electric
				  utility shall withdraw the interconnection application.
(5) Within 30 business days after the
				  applicant pays the applicable supplemental review fee or fees, and provides
				  reasonable requested data, an electric utility shall perform a supplemental
				  review and notify the applicant of the results. The supplemental review must
				  consist of applying the supplemental review screens selected by the electric
				  utility pursuant to subrule (3) of this rule to the proposed DER. The electric
				  utility shall not require a system impact study if the DER passes the applied
				  supplemental review screens.
(6)
				  The supplemental review screens must include all of the following:
(a) Minimum load screen. Where 12 months of
				  line section minimum load data, including onsite load but not station service
				  load served by the proposed DER, are available, can be calculated, can be
				  estimated from existing data, or can be determined from a power flow model, the
				  aggregate DER capacity on the line section must be less than 100% of the
				  minimum load for all line sections bounded by automatic sectionalizing devices
				  upstream of the proposed DER. If minimum load data are not available, or cannot
				  be calculated, estimated, or determined, an electric utility shall include the
				  reason or reasons that it is unable to calculate, estimate, or determine
				  minimum load in its supplemental review results notification under subrules (7)
				  and (8) of this rule. All of the following must be applied by the electric
				  utility:
(i) The type of generation used by
				  the proposed DER will be considered when calculating, estimating, or
				  determining circuit or line section minimum load relevant for the application
				  of the minimum load screen specified in this subrule. Solar photovoltaic
				  generation systems with no battery storage must use daytime minimum load. All
				  other generation must use absolute minimum load unless an operating schedule is
				  provided.
(ii) When this screen is
				  being applied to a DER that serves some station service load, only the net
				  injection of electric energy into the electric utility's distribution system
				  may be considered as part of the aggregate generation.
(iii) The electric utility shall not consider
				  as part of the aggregate generation, for purposes of this supplemental screen,
				  DER capacity known to be already reflected in the minimum load data.
