Washington Administrative Code › Title 480 - Utilities and Transportation Commission › Chapter 480-108 - Electric companies-Interconnection with electric generators › Section 480-108-010 - Definitions

Current through Register Vol. 24-14, July 15, 2024
"Application"
means the written notice as defined
				in WAC 480-108-030 that the
				interconnection customer provides to the electrical company to initiate the
				interconnection process.
"Business day"
means Monday through Friday
				excluding official federal and state holidays.
"Certificate of completion"
means the form
				described in WAC
				480-108-050 that must be
				completed by the interconnection customer and the electrical inspector having
				jurisdiction over the installation of the facilities indicating completion of
				installation and inspection of the interconnection. As provided in WAC
				480-108-050, the certificate of
				completion must be reviewed and approved, in writing, by the electrical company
				before the interconnection customer's generation facility may be connected and
				operated in parallel with the electrical company's electrical system.
"Commission"
means the Washington utilities and
				transportation commission.
"Electric system"
means all electrical wires,
				equipment, and other facilities owned by the electrical company that are used
				to transmit electricity to customers.
"Electrical company"
means any public service
				company, as defined by
				RCW
				80.04.010, engaged in the generation,
				distribution, sale or furnishing of electricity and subject to the jurisdiction
				of the commission.
"Generating facility"
means a source of
				electricity owned by the interconnection customer that is located on the
				interconnection customer's side of the point of common coupling, and all
				ancillary and appurtenant facilities, including interconnection facilities,
				which the interconnection customer requests to interconnect to the electrical
				company's electric system.
["]
Grid network distribution system"
means electrical service from a distribution system consisting of two or more
				primary circuits from one or more substations or transmission supply points
				arranged such that they collectively feed secondary circuits serving more than
				one location and more than one electrical company customer.
"Interconnection customer"
means the person,
				corporation, partnership, government agency, or other entity that owns and
				operates a generating facility interconnected or requested to be interconnected
				to the electrical company's electric system. The interconnection customer may
				assign to another party responsibility for compliance with the requirements of
				this rule only with the express written permission of the electrical
				company.
"Initial operation"
means the first time the
				generating facility is in parallel operation with the electric system.
"In-service date"
means the date on which the
				generating facility and any related facilities are complete and ready for
				service, even if the generating facility is not placed in service on or by that
				date.
"Interconnection"
means the physical connection of
				a generating facility to the electric system so that parallel operation may
				occur.
"Interconnection facilities"
means the electrical
				wires, switches and other equipment owned by the electrical company or the
				interconnection customer and used to interconnect a generating facility to the
				electric system. Interconnection facilities are located between the generating
				facility and the point of common coupling. Interconnection facilities do not
				include system upgrades.
"Model interconnection agreement"
means a written
				agreement including standardized terms and conditions that govern the
				interconnection of generating facilities pursuant to this chapter. The model
				interconnection agreement may be modified to accommodate terms and conditions
				specific to individual interconnections, subject to the conditions set forth in
				these rules.
"Net metering"
means measuring the difference
				between the electricity supplied by an electrical company and the electricity
				generated by a generating facility that is fed back to the electrical company
				over the applicable billing period.
"Network protectors"
means devices installed on a
				spot network distribution system designed to detect and interrupt reverse
				current-flow (flow out of the network) as quickly as possible, typically within
				three to six cycles.
"Parallel operation"
or
"operate in
				parallel"
means the synchronous operation of a generating facility while
				interconnected with an electrical company's electric system.
"Point of common coupling"
or
"PCC"
means the point where the generating facility's local electric power system
				connects to the electrical company's electric system, such as the electric
				power revenue meter or at the location of the equipment designated to
				interrupt, separate or disconnect the connection between the generating
				facility and electrical company. The point of common coupling is the point of
				measurement for the application of IEEE 1547, clause 4.
"PURPA qualifying facility"
means a generating
				facility that meets the criteria specified by the Federal Energy Regulatory
				Commission (FERC) in 18 C.F.R. Part 292 Subpart B and that sells power to an
				electrical company under chapter 480-107 WAC.
"Spot network distribution system"
means
				electrical service from a distribution system consisting of two or more primary
				circuits from one or more substations or transmission supply points arranged
				such that they collectively feed a secondary circuit serving a single location
				(e.g., a large facility or campus) containing one or more electrical company
				customers.
"System upgrades"
means the additions,
				modifications and upgrades to the electrical company's electrical system at or
				beyond the point of common coupling necessary to facilitate the interconnection
				of the generating facility. System upgrades do not include interconnection
				facilities.
