Wisconsin Administrative Code › Public Service Commission › Chapter PSC 119 - Rules For Interconnecting Distributed Generation Facilities › Subchapter I - General › Section PSC 119.02 - Definitions

Current through June 24, 2024
In this chapter:
(1) "ANSI" means American National Standards
				Institute.
(2) "Applicant" means
				the legally responsible person applying to a public utility to interconnect a
				DG facility to the public utility's distribution system.
(3) "Application review" means a review by
				the public utility of the completed standard application form for
				interconnection, to determine if an engineering review or distribution system
				study is needed.
(4) "Category 1"
				means a DG facility with an export capacity of 20 kW or less. A DG facility
				comprised of a resource no larger than 20 kW with a non-exporting energy
				storage system no larger than 20 kW shall be considered a Category 1
				system.
(5) "Category 2" means a DG
				facility with an export capacity of greater than 20 kW and not more than 200
				kW. The nameplate rating shall be used instead of the export capacity for this
				definition if the non-exporting energy storage system is larger than 20
				kW.
(6) "Category 3" means a DG
				facility with an export capacity of greater than 200 kW and not more than 1 MW.
				The nameplate rating shall be used instead of the export capacity for this
				definition if the non-exporting energy storage system is larger than 200
				kW.
(7) "Category 4" means a DG
				facility with an export capacity of greater than 1 MW and not more than 15
				MW.
(8) "Certified equipment" means
				a generating, control or protective system that has been certified by a
				nationally recognized testing laboratory as meeting acceptable safety and
				reliability standards.
(9)
				"Commission" means the public service commission of Wisconsin.
(10) "Commissioning test" means the process
				of documenting and verifying the performance of a DG facility so that it
				operates in conformity with the design specifications.
(11) "Customer" means any person who is
				receiving electric service from a public utility's distribution
				system.
(12) "DG" means distributed
				generation.
(13) "DG facility" has
				the meaning given in s. 196.496 (1), Stats.
(14) "Distribution feeder" means an electric
				line from a public utility substation or other supply point to customers that
				is operated at 50 kV or less, or as determined by the commission.
(15) "Distribution system" means all
				electrical wires, equipment, and other facilities owned or provided by a public
				utility that are normally operated at 50 kV or less.
(16) "Distribution system study" means a
				study to determine if a distribution system upgrade is needed to accommodate
				the proposed DG facility and to determine the cost of any such
				upgrade.
(16d) "Energy storage
				system" means a device or devices that capture energy produced at one time,
				store that energy for a period of time, and deliver that energy as electricity
				for use at a future time.
(16h)
				"Energy storage system max continuous output kW in alternating current" means
				the maximum rated continuous power output of the energy storage system.
Note:
This defined term should be used when
				  completing the standard application form, PSC Form 6031.
(16p) "Energy storage system max usable
				energy kWh in alternating current" means the maximum rated amount of energy
				stored in the energy storage system.
Note:
This defined term should be used when
				  completing the standard application form, PSC Form 6031.
(16t) "Energy storage system peak output kW
				in alternating current" means while grid interactive, the maximum short
				duration rated output power of the energy storage system to the distribution
				system.
Note:
This defined term should be used when
				  completing the standard application form, PSC Form 6031.
(17) "Engineering review" means a study that
				may be undertaken by a public utility, in response to its receipt of a
				completed standard application form for interconnection, to determine the
				suitability of the installation.
(17m) "Export capacity kW in alternating
				current" means the amount of power that can be transferred from the DG facility
				to the distribution system. Export capacity is the lesser of the following:
(a) The nameplate rating.
(b) If limited using any approved means, that
				limited amount.
