PERMANENT RULES
COMMISSION
1 STATUTORY OR OTHER AUTHORITY: The Washington utilities and transportation commission takes this action under Notice No. WSR 06-03-126, filed with the code reviser on January 18, 2006. The commission brings this proceeding pursuant to RCW 80.01.040 and 80.04.160.
2 STATEMENT OF COMPLIANCE: This proceeding complies with the Administrative Procedure Act (chapter 34.05 RCW), the State Register Act (chapter 34.08 RCW), the State Environmental Policy Act of 1971 (chapter 43.21C RCW), and the Regulatory Fairness Act (chapter 19.85 RCW).
3 DATE OF ADOPTION: The commission adopts this rule on the date that is order is entered.
4 CONCISE STATEMENT OF PURPOSE AND EFFECT OF THE RULE: RCW 34.05.325(6) requires that the commission prepare and provide to commenters a concise explanatory statement about an adopted rule. The statement must include the identification of the commission's reasons for adopting the rule, a description of the difference between the version of the proposed rules published in the register and the rules as adopted (other than editing changes), a summary of the comments received regarding the proposed rule changes, and the commission's responses to the comments, reflecting the commission's consideration of them.
5 The commission often includes a discussion of those matters in its rule adoption order. In addition, to avoid unnecessary duplication, the commission designates the discussion in this order as its concise explanatory statement, supplemented where not inconsistent by the staff memoranda. Together, the documents provide a complete but concise explanation of the agency actions and its reasons for taking those actions.
6 The rules establish standards for interconnection of consumer-owned power generation facilities up to 25 kW capacity to electric utility delivery systems. These regulations include standards for applications for interconnection, processing of such applications, technical and engineering standards for interconnections, safety standards, insurance and liability provisions, and other provisions.
7 The commission is adopting this rule to advance state policy to encourage the use of renewable energy technologies.1
1 RCW 80.28.025 Establishes a state policy to encourage electric power resources from renewable sources through use of
incentives.
8 SSB 5101, chapter 300, Laws of 2005, states that "the
legislature intends to provide incentives for the greater use
of locally created renewable energy technologies." SSB 5101
also provides that utilities, in return for a credit against
the public utility excise tax, may supply an incentive payment
to consumers for consumer-generated electricity from renewable
energy systems. However, the incentive payments created by
SSB 5101 are only available to customers connected to the
distribution system of a light and power business if "uniform
standards for interconnection to the electric distribution
system" are in effect for utilities serving eighty percent of
total customer load in the state.
Establishing standards for interconnection of customer-owned power generation facilities to the delivery systems of the investor-owned utilities constitutes substantial progress toward meeting the threshold condition established by SSB 5101 for customer incentive payments.
9 The rules encourage small-scale, customer-owned distributed generation facilities by establishing uniformity among the investor-owned utilities regarding technical and process standards for interconnection of such facilities to utility delivery systems.
10 In addition, recently enacted amendments to Section 111(d) of the Public Utility Regulatory Policies Act of 1978 (16 U.S.C. 2621(d)) require the commission to consider and determine whether to establish standards for interconnection. The commission's inquiry and adoption of this rule complies with this requirement.
11 REFERENCE TO AFFECTED RULES: This order establishes the first portion of a new chapter of Washington Administrative Code, chapter 480-108 WAC, Electric companies -- Interconnection with electric generators.
12 The commission intends to continue investigation of facilities greater than 25 kW in a supplemental CR-102.
13 This order adopts the following sections of Washington Administrative Code: WAC 480-108-001 Purpose and scope, 480-108-005 Application of rules, 480-108-010 Definitions, 480-108-020 Technical standards for interconnection, 480-108-030 Application for interconnection, 480-108-040 General terms and conditions of interconnection, 480-108-050 Certificate of completion, 480-108-060 Required filings -- Exceptions, and 480-108-999 Adoption by reference.
14 PREPROPOSAL STATEMENT OF INQUIRY AND ACTIONS THEREUNDER: The commission filed a preproposal statement of inquiry (CR-101) on August 12, 2005, at WSR 05-17-083. The statement advised interested persons that the commission was considering entering a rule making to establish regulations to govern the interconnection of consumer-owned power generation facilities to utility delivery facilities.
15 ADDITIONAL NOTICE AND ACTIVITY PURSUANT TO PREPROPOSAL STATEMENT: The commission informed persons of its inquiry into this matter by providing notice of the subject and the CR-101 to all persons on the commission's list of persons requesting such information pursuant to RCW 34.05.320(3) and the commission's lists of all registered electric and gas companies, persons interested in electric and gas issues, as well as to attorneys representing these companies. The commission posted the relevant rule making information on its internet web site at http://www.wutc.wa.gov/051106. In its notice the commission posed two questions and invited interested persons to respond and make proposals addressing electrical interconnection. The two questions were:
1. If the commission establishes regulations governing interconnection to utility distribution or transmission facilities that are not FERC-jurisdictional, should it strive for consistency with the FERC standards?
2. Do the FERC regulations in Order No. 2006 (particularly Appendices "E" and "F") represent a good technical framework for commission regulations to govern interconnection? What modifications and adjustments would be necessary if the commission were to use the FERC rules as a model?
The commission also welcomed any comprehensive recommendations or proposals that stakeholders or utilities might propose for statewide standards for interconnection as an alternative to the FERC model.
16 Pursuant to the notice, the commission received comments on October 14, 2005, from the following companies, organizations, and interested persons: Industrial Customers of Northwest Utilities ("ICNU"), the Renewable Northwest Project ("RNP")2, and the Washington load-serving utilities ("utilities")3. The utilities proposed a set of standards that they jointly developed and recommended as a framework for establishing interconnection standards to be used by both commission-jurisdictional utilities and public utilities that are not jurisdictional to the commission.4
2The Renewable Northwest Project submitted joint comments along with the American Wind Energy Association and the
Northwest Energy Coalition.
3The load-serving utilities, a group consisting of Puget Sound Energy, Avista Corporation, PacificCorp, Benton REA, Big Bend Rural Electric Cooperative, Chelan County PUD, City of Port Angeles, Clark Public Utilities, Elmhurst Mutual, Grant County PUD, Kittitas County PUD, Lewis County PUD, Seattle City Light, Snohomish County PUD, Tacoma Power, the Washington PUD Association, Western Rural Electric Cooperative Association, and the Association of Washington Cities.
4The commission commends the investor-owned and public utilities for working cooperatively to develop a proposed set of uniform interconnection standards. We particularly appreciate the constructive participation in our inquiry and rule-making process of the public utilities that are not within our jurisdiction.
17 The commission convened a workshop on December 2,
2005, to discuss interconnection issues and the utilities'
proposal. More than forty interested persons attended and
participated in the workshop.

The electrical company will process the application and provide interconnection in a time frame consistent with the average of other service connections.
(4) Application evaluation. All generation interconnection requests pursuant to this chapter will be reviewed by the utility for compliance with the rules of this chapter. If the utility in its sole discretion finds that the application does not comply with this chapter, the utility may reject the application. If the utility rejects the application, it shall provide the applicant with written notification stating its reasons for rejecting the application.
[]
(1) Any electrical generating facility with a maximum electrical generating capacity of 25 kW or less must comply with these rules to be eligible to interconnect and operate in parallel with the electrical company's electric system. The rules under this chapter shall apply to all interconnecting generating facilities that are intended to operate in parallel with an electrical company's electric system irrespective of whether the applicant intends to generate energy to serve all or a part of the applicant's load; or to sell the output to the electrical company or any third party purchaser.
(2) In order to ensure system safety and reliability of interconnected operations, all interconnected generating facilities shall be constructed and operated by generator in accordance with this chapter and all other applicable federal, state, and local laws and regulations.
(3) Prior to initial operation, all generators must submit a completed certificate of completion to the electrical company, execute an appropriate interconnection agreement and any other agreement(s) required for the disposition of the generating facility's electric power output as described in WAC 480-108-040(14). The interconnection agreement between the electrical company and generator outlines the interconnection standards, cost allocation and billing agreements, and on-going maintenance and operation requirements.
(4) Applicant or generator shall promptly furnish the electrical company with copies of such plans, specifications, records, and other information relating to the generating facility or the ownership, operation, use, or maintenance of the generating facility, as may be reasonably requested by the electrical company from time to time.
(5) For the purposes of public and working personnel safety, any nonapproved generation interconnections discovered will be immediately disconnected from the electrical company system.
(6) To ensure reliable service to all electrical company customers and to minimize possible problems for other customers, the electrical company will review the need for a dedicated-to-single-customer distribution transformer. Interconnecting generating facilities under 25 kW may require a separate transformer. If the electrical company requires a dedicated distribution transformer, the applicant or generator shall pay for all costs of the new transformer and related facilities.
(7) Metering.
(a) Net metering for solar, wind, hydropower and fuel cells as set forth in chapter 80.60 RCW: The electrical company shall install, own and maintain a kilowatt-hour meter, or meters as the installation may determine, capable of registering the bi-directional flow of electricity at the point of common coupling at a level of accuracy that meets all applicable standards, regulations and statutes. The meter(s) may measure such parameters as time of delivery, power factor, voltage and such other parameters as the electrical company shall specify. The applicant shall provide space for metering equipment. It will be the applicant's responsibility to provide the current transformer enclosure (if required), meter socket(s) and junction box after the applicant has submitted drawings and equipment specifications for electrical company approval. The electrical company may approve other generating sources for net metering but is not required to do so.
(b) Production metering: The electrical company may require separate metering for production. This meter will record all generation produced and may be billed separately from any net metering or customer usage metering. All costs associated with the installation of production metering will be paid by the applicant.
(8) Common labeling furnished or approved by the electrical company and in accordance with NEC requirements must be posted on meter base, disconnects, and transformers informing working personnel that generation is operating at or is located on the premises.
(9) As currently set forth for qualifying generation under chapter 80.60 RCW, for solar, wind, hydro or fuel cells, no additional insurance will be necessary. For other generating facilities permitted under these standards but not contained within chapter 80.60 RCW, additional insurance, limitations of liability and indemnification may be required by the electrical company.
(10) Prior to any future modification or expansion of the generating facility, the generator will obtain electrical company review and approval. The electrical company reserves the right to require the generator, at the generator's expense, to provide corrections or additions to existing electrical devices in the event of modification of government or industry regulations and standards.
(11) For the overall safety and protection of the electrical company system, chapter 80.60 RCW currently limits interconnection of generation for net metering to 0.1% of the electrical company's peak demand during 1996. Additionally, interconnection of generating facilities to individual distribution feeders will be limited to 10% of the feeder's peak capacity. However, the electrical company may, in its sole discretion, allow additional generation interconnection beyond these stated limits.
(12) It is the responsibility of the generator to protect its facilities, loads and equipment and comply with the requirements of all appropriate standards, codes, statutes and authorities.
(13) Charges by the electrical company to the applicant or generator in addition to the application fee, if any, will be compensatory and applied as appropriate. Such costs may include, but are not limited to, transformers, production meters, and electrical company testing, qualification, and approval of non-UL 1741 listed equipment. The generator shall be responsible for any costs associated with any future upgrade or modification to its interconnected system required by modifications in the electrical company's electric system.
(14) This section does not govern the settlement, purchase or delivery of any power generated by applicant's generating facility. The purchase or delivery of power, including net metering of electricity pursuant to chapter 80.60 RCW, and other services that the applicant may require will be covered by separate agreement or pursuant to the terms, conditions and rates as may be from time to time approved by the commission. Any such agreement shall be complete prior to initial operation and filed with the commission.
(15) Generator may disconnect the generating facility at any time; provided, that the generator provide reasonable advance notice to the electrical company.
(16) Generator shall notify the electrical company prior to the sale or transfer of the generating facility, the interconnection facilities or the premises upon which the facilities are located. The applicant or generator shall not assign its rights or obligations under any agreement entered into pursuant to these rules without the prior written consent of electrical company, which consent shall not be unreasonably withheld.
