Wash. Admin. Code § 480-108-010
"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.
