Illinois Administrative Code › Title 83 - PUBLIC UTILITIES › Part 467 - ELECTRIC INTERCONNECTION OF LARGE DISTRIBUTED ENERGY RESOURCES FACILITIES › Section 467.20 - Definitions and Incorporations by Reference

Current through Register Vol. 48, No. 28, July 12, 2024
Terms defined in Section 16-102 of the Public Utilities Act [220
				ILCS 5 ] shall have the same meaning for purposes of this Part as they have under
				Section 16-102 of the Act, unless further defined in this Part. The following words
				and terms, when used in this Part, have the following meanings unless the context
				indicates otherwise:
"Act" means the Public Utilities Act [220 ILCS 5 ].
"Adverse system impact" means a negative effect that compromises the
				safety or reliability of the electric distribution or transmission systems or
				materially affects the quality of electric service provided by the electric
				distribution company (EDC) to other customers.
"Affected system" means an electric system, other than the EDC's
				distribution system with which the distributed energy resources facility is to be
				directly connected, that could suffer an adverse system impact from the proposed
				interconnection.
"Applicant" means a person (or entity) who has submitted an
				interconnection request to interconnect a distributed energy resources facility to
				an EDC's electric distribution system.
"Business day" means Monday through Friday, excluding State and
				federal holidays.
"Calendar day" means any day, including Saturdays, Sundays and State
				and federal holidays.
"Certificate of completion" means a certificate, in a form approved
				by the Commission, that contains information about the interconnection equipment to
				be used, its installation and local inspections (see Appendix A).
"Commissioning test" means tests applied to a distributed energy
				resources facility by the applicant after construction is completed to verify that
				the facility does not create adverse system impacts and performs to the submitted
				specifications.
"Contingent upgrades" means proposed interconnection facilities or
				distribution system upgrades, identified during interconnection studies for an
				applicant's interconnection request, that are the responsibility of an
				interconnection request earlier in the queue than the subject application for
				interconnection. The identified contingent upgrades are required in order for the
				applicant's proposed interconnection request to receive permission to operate and,
				if delayed or not built by the earlier-queued interconnection request, could cause a
				need for restudies of the interconnection request and may become the responsibility
				of the applicant's interconnection request.
"Distributed energy resources facility" or "DER facility" means the
				equipment used by an interconnection customer to generate or store electricity that
				operates in parallel with the electric distribution system. A DER facility may
				include, but is not limited to, an electric generator or energy storage system, a
				prime mover, and the interconnection equipment required to safely interconnect with
				the electric distribution system or local electric power system.
"Electric distribution company" or "EDC" means any electric utility
				subject to the jurisdiction of the Commission.
"Electric distribution system" means the facilities and equipment
				owned and operated by the EDC and used to transmit electricity to ultimate usage
				points such as homes and industries from interchanges with higher voltage
				transmission networks that transport bulk power over longer distances. The voltage
				levels at which electric distribution systems operate differ among areas, but
				generally operate at less than 100 kilovolts of electricity. "Electric distribution
				system" has the same meaning as the term "Area EPS", as defined in Section 3.1.6.1
				of IEEE Standard 1547. "Electric distribution system" excludes facilities under the
				operational control of the RTO.
"IEEE Standard 1547" is the Institute of Electrical and Electronics
				Engineers, Inc., 3 Park Avenue, New York NY 10016-5997, Standard 1547 (2003)
				"Standard for Interconnecting Distributed Resources with Electric Power Systems".
				This incorporation does not include any later amendments or editions.
"IEEE Standard 1547.1 " is the IEEE Standard 1547.1(2005)
				"Conformance Test Procedures for Equipment Interconnecting Distributed Resources
				with Electric Power Systems". This incorporation does not include any later
				amendments or editions.
"Interconnection customer" means a person or entity that has a DER
				facility interconnected, or that seeks to interconnect, to an electric distribution
				system.
"Interconnection equipment" means a group of components or an
				integrated system owned and operated by the interconnection customer that connects
				an electric generator with a local electric power system, as that term is defined in
				Section 3.1.6.2 of IEEE Standard 1547, or with the electric distribution system.
				Interconnection equipment is all interface equipment, including switchgear,
				protective devices, inverters or other interface devices. Interconnection equipment
				may be installed as part of an integrated equipment package that includes a
				generator or other electric source.
"Interconnection facilities" means facilities and equipment required
				by the EDC to accommodate the interconnection of a DER facility. Collectively,
				interconnection facilities include all facilities and equipment between the DER
				facility's interconnection equipment and the point of interconnection, including any
				modifications or additions necessary to physically and electrically interconnect the
				DER facility to the electric distribution system. Interconnection facilities are
				sole use facilities and do not include system upgrades.
"Interconnection request" means an applicant's request, in a form
				approved by the Commission, for interconnection of a new DER facility or to change
				the capacity or other operating characteristics of an existing DER facility already
				interconnected with the electric distribution system.
"Interconnection study" is any study described in Section
				467.70.
"Local electric power system" means facilities that deliver electric
				power to a load that is contained entirely within a single premises or group of
				premises. Local electric power system has the same meaning as in Section 3.1.6.2 of
				IEEE Standard 1547.
"Nameplate capacity" is the maximum rated output in kVA of a
				generator, prime mover, energy storage system, or other electric power production
				equipment under specific conditions designated by the manufacturer and usually
				indicated on a nameplate physically attached to the power production
				equipment.
"Parallel operation" or "parallel" means a DER facility that is
				connected electrically to the electric distribution system for longer than 100
				milliseconds.
"Point of interconnection" or "POI" means the point where the DER
				facility is electrically connected to the electric distribution system. Point of
				interconnection has the same meaning as the term "point of common coupling" defined
				in Section 3.1.13 of IEEE Standard 1547.
"Queue position" means the order an EDC receives a completed
				interconnection request relative to that specific EDC's other interconnection
				requests. It is established by the date that the EDC receives the completed
				interconnection request.
"Scoping meeting" means a meeting between representatives of the
				applicant and EDC conducted for the purpose of discussing interconnection issues and
				exchanging relevant information.
"Standard agreement for interconnection of DER facilities with a
				capacity more than 10 MVA" means a standard interconnection agreement applicable to
				interconnection requests for large DER facilities (see Appendix C).
"Witness test" means a verification by the EDC, either by on-site
				observation or review of documents, that the interconnection installation evaluation
				required by the applicable technical standards has been performed.
