(1) The rules in this chapter explain the renewable energy system incentive program, which is administered by the Washington State University energy program (hereinafter referred to as "energy program"). It is the legislature's intent to provide the incentives as described in RCW 82.16.130 in order to ensure the sustainable job growth and vitality of the state's renewable energy sector. The purpose of the incentive is to reduce the costs associated with installing and operating renewable energy systems by persons or entities receiving the incentive. This incentive program authorizes an incentive payment based on electricity generated by renewable energy systems located in Washington state. Qualified renewable energy systems include:

(a) Solar energy systems;

(b) Wind generators; and

(c) Certain types of anaerobic digesters that process manure from livestock into biogas and dried manure using microorganisms in a closed oxygen-free container, in which the biogas (such as methane) fuels a generator that generates electricity.

(2) The rules in this chapter are divided into seven parts based on subject matter, as follows:

(a) Part I: Definitions;

(b) Part II: Participation and application requirements, and incentive levels by project type;

(c) Part III: Calculation of incentives;

(d) Part IV: General topics;

(e) Part V: Manufactured in Washington state;

(f) Part VI: Application process for currently certified renewable energy systems in the cost recovery incentive program; and

(g) Part VII: Appeals rights.

The definitions in Part I of this chapter (this section and WAC 504-49-103 through 504-49-195) apply throughout this chapter unless the context clearly requires otherwise.

The term "administrator" has the following two meanings in this chapter:

(1) For purposes of a shared commercial solar project, the administrator is a utility or a business under contract with a utility which administers a shared commercial solar project that meets the eligibility requirements specified in this chapter. The administrator applies for certification on behalf of each of the project participants. In addition, the administrator performs administrative tasks on behalf of the owners as may be necessary, such as:

(a) Receiving the renewable energy incentive payments;

(b) Allocating and paying appropriate amounts of such payments to owners; and

(c) Communicating with the energy program about any changes in participants.

(2) For purposes of a community solar project as defined in WAC 504-49-120, the administrator is the utility, nonprofit, or local housing authority (as defined in RCW 35.82.020) that organizes and administers the community solar project. The administrator is responsible for applying for the renewable energy system incentive on behalf of the system's owners. In addition, the administrator performs administrative tasks on behalf of the owners as may be necessary, such as:

(a) Receiving the renewable energy incentive payments;

(b) Allocating and paying appropriate amounts of such payments to owners; and

(c) Communicating with the energy program about any changes in participants.

"Caps and limits" are defined as follows:

(c) Thirty-five thousand dollars per year for shared commercial solar projects.

(2) Example: Two or more individuals living together in one household, with one customer account with the participating utility, constitutes a household. Although they may each individually participate in this incentive program, these same individuals living together in one household receive incentives in accordance with this chapter.

"Program term" means eight years, or until cumulative incentive payments for electricity produced by the project reach fifty percent of the total system price, including applicable sales tax, whichever occurs first. Eight years is equivalent to ninety-six months of electricity generation from the time of certification.

"Project participant" has the two following meanings:

(1) For purposes of community solar projects, a utility customer who participates in a community solar project in order to obtain a beneficial interest. Eligible participants of a community solar project that are business entities, such as a limited liability company or a corporation, are analyzed for participant eligibility and applicable incentive caps and limits by looking through the business entity to the members or stockholders that own the business entity.

(2) The utility may terminate its voluntary participation in the incentive program by providing notice in writing to the energy program to cease issuing new certifications for renewable energy systems that would be served by that utility.

(3) Such notice of termination of participation is effective after fifteen days, at which point the energy program may not accept new applications for certification of renewable energy systems that would be served by that utility.

(4) Upon receiving a utility's notice of termination of participation in the incentive program, the energy program must report on its website that customers of that utility are no longer eligible to receive new certifications under the incentive program.

(5) A utility's termination of participation does not affect the utility's obligation to continue to make annual incentive payments for electricity generated by systems that were certified prior to the effective date of the notice. The energy program must continue to process and issue certifications for renewable energy systems that were received by the energy program before the effective date of the notice of termination.

(6) A utility that has terminated participation in the program may resume participation upon filing notice with the energy program.

No new certification may be issued under this chapter for a system which an applicant received notice of eligibility from the department of revenue under the cost recovery program (RCW 82.16.120), or for a renewable energy system served by a utility that has elected not to participate in the incentive program, as provided in WAC 504-49-200.

Any person, business, or household, as defined in WAC 504-49-150, that participates in any of the four types of renewable energy projects defined in sections 5 through 8, chapter 36, Laws of 2017, 3rd sp. sess.

This notice must state the rate to be paid per kilowatt-hour of electricity generated by the renewable energy system, as provided in section 6(12), chapter 36, Laws of 2017, 3rd sp. sess. (ESSB 5939), subject to any applicable caps and limits on total annual payment as defined in this chapter.

System certifications and the information contained therein are subject to public disclosure. In addition, all energy generation and incentive payment information associated with the certified system (as collected by the energy program) is subject to public disclosure.

The energy program may deny or revoke the approval of a system's certification and an appeal of this final determination may be initiated. The appeal provisions under Part VII of this chapter apply here.

A utility is not liable for incentive payments to a customer-owner if the utility has disconnected the customer due to a violation of a customer service agreement, such as nonpayment of the customer's bill or a violation of an interconnection agreement.

Modification details must be provided to the energy program. Examples are provided in WAC 504-49-305.

The incentive payment rate is the sum of the base rate and the made-in-Washington bonus, if applicable. To determine the incentive payment, the incentive payment rate is then multiplied by the system's gross kilowatt-hours generated during the fiscal year to determine the incentive payment.

(1) Determining the base rate. The first step in computing the incentive payment is to determine the correct base rate to apply. This rate depends on the fiscal year in which the system was certified and the type of renewable energy project under consideration, as defined in the table in subsection (2) of this section.

(2) Made-in-Washington bonus. The bonus rate is determined by whether all applicable system components (solar modules, wind turbines or towers) are manufactured in Washington state. See additional manufacturing details in Part V of this chapter. Bonus rates vary depending on the fiscal year in which the system is certified, as provided in the table below.

(3) Examples: A renewable energy system certified in fiscal year 2019 and generate:

(a) Residential-scale system: Two thousand five hundred kilowatt-hours; commercial-scale system: Fourteen thousand kilowatt-hours.

(i) If a residential-scale or commercial-scale renewable energy system has only solar modules manufactured out-of-state, the computation is as follows:

(A) Residential-scale: 0.14 × 2,500 = $350.00;

(B) Commercial-scale: 0.04 × 14,000 = $560.00.

(ii) If a residential-scale or commercial-scale renewable energy system has all solar modules manufactured in Washington state, the computation is as follows:

(A) Residential-scale: (0.14 + 0.04) × 2,500 = $450.00;

(B) Commercial-scale: (0.04 + 0.04) × 14,000 = $1,120.00.

(iii) If a residential-scale or commercial-scale renewable energy system has a solar module manufactured in Washington state combined with additional solar modules manufactured out-of-state, the computation would be as follows:

(A) Residential-scale: 0.14 × 2,500 = $350.00;

(B) Commercial-scale: 0.04 × 14,000 = $560.00.

(iv) If residential-scale or commercial-scale wind generator equipment has an out-of-state turbine combined with a tower manufactured in Washington state, the computation is as follows:

(A) Residential-scale: (0.14 + 0.04) × 2,500 = $450.00;

(B) Commercial-scale: (0.04 + 0.04) × 14,000 = $1,120.00.

(v) If residential-scale wind generator equipment has both an out-of-state turbine and tower, the computation is as follows:

(A) Residential-scale: 0.14 × 2,500 = $350.00;

(B) Commercial-scale: 0.04 × 14,000 = $560.00.

(b) Shared commercial solar project system: Four million kilowatt-hours.

(i) If a shared commercial system has out-of-state solar modules, the computation is as follows: 0.04 × 4,000,000 = $160,000.00. The solar project administrator distributes the incentive payments consistent with share of participation. If a participant is involved at five percent of the project, their incentive payment is $160,000.00 × 0.05 = $8,000.00 (contingent on the rates, fees, terms or conditions of the project).

(ii) If a shared commercial system has all solar modules manufactured in Washington state, the computation is as follows: (0.04 + 0.04) × 4,000,000 = $320,000.00. The solar project administrator distributes the incentive payments consistent with share of participation. If a participant is involved at five percent of the project, their incentive payment is $320,000.00 × 0.05 = $16,000.00 (contingent on the rates, fees, terms or conditions of the project).

(c) Community solar project system: Fifty thousand kilowatt-hours.

(i) If a community solar energy system has all solar modules manufactured in Washington state combined with an out-of-state inverter, the computation is as follows: (0.14 + 0.04) × 50,000 = $9,000.00. The solar project administrator distributes the incentive payments consistent with share of participation. If a participant is involved at five percent of the project, their incentive payment is $9,000.00 × 0.05 = $450.00 (contingent on the rates, fees, terms or conditions of the project).

(ii) If a community solar energy system has some solar modules manufactured in Washington state combined with additional solar modules manufactured out-of-state, the computation is as follows: 0.14 × 50,000 = $7,000.00. The solar project administrator distributes the incentive payments consistent with share of participation. If a participant is involved at five percent of the project, their incentive payment is $7,000.00 × 0.05 = $350.00 (contingent on the rates, fees, terms or conditions of the project).

(1) All additions or changes to existing certified systems may be subject to existing utility standards and policies.

(2) If a residential-scale or commercial-scale customer-owner makes investments that result in an expansion of capacity, the applicant must provide this information to the energy program. The energy program may:

(a) Issue a new certification for an additional system installed with a previously certified system, as long as the new system meets the program requirements and its production can be measured separately from the previously certified system. These systems may be subject to additional annual reporting requirements including, but not limited to, production meter readings from each system.

(b) Issue a recertification if the additional capacity is not measured separately. Such recertification expires on the same day as the original certification for the residential-scale or commercial-scale system, and applies the incentive rates and program rules that are in effect as of the date of the recertification.

(3) The following examples illustrate how increases in system capacity may affect incentive payments:

(a) A five kilowatts direct current residential-scale system is certified in February 2019 and is eligible for the fourteen cents incentive rate. Two kilowatts direct current of capacity is added in February 2021 without a separate production meter and the system is recertified in the same fiscal year. The incentive rate of ten cents per kilowatt-hour applies to all future incentive payments of the entire seven kilowatts direct current system. Incentive payments end in 2027 or when cumulative incentive payments reach fifty percent of the total system price plus the expansion price, including applicable sales tax, whichever comes first;

(b) A five kilowatts direct current residential-scale system is certified in February 2019 and is eligible for the fourteen cents incentive rate. If two kilowatts direct current of capacity is added in February 2021 with its own production meter, the addition may be certified separately and the ten cent rate applies only to the production from this separate system and ends in 2029. The originally certified five kilowatts direct current system continues to be certified at the fourteen cents rate, with those payments ending in 2027. Cumulative incentive payments of fifty percent of the total system price, including applicable sales tax, apply separately to the five kilowatts direct current and two kilowatts direct current installations;

(c) An increase in nameplate capacity, production metered or not, results in the total capacity being greater than twelve kilowatts direct current. Recertification is required and the applicable commercial-scale incentive rate will apply.

Incentive payments continue for eight years or until cumulative incentive payments for electricity produced by the project reach fifty percent of the total system price, including applicable sales tax, whichever occurs first.

The energy program must, in consultation with the department of commerce, establish a list of equipment that is eligible for the bonus rates described in this chapter.

(1) In order for a solar module, or a wind turbine or tower, to qualify as manufactured in Washington state, the manufactured component must meet the following definitions:

(a) "Solar module" means the smallest nondivisible, self-contained physical structure housing interconnected photovoltaic cells and providing a single direct current electrical output. The lamination of the modules must occur in Washington state;

(b) "Wind turbine" refers to a device that converts the wind's kinetic energy into electrical energy and "tower" refers to the supporting structure.

(2) Is combining products considered to be manufacturing? When determining whether a solar module, or a wind turbine or tower, are manufactured in Washington, the energy program considers various factors to determine if a manufacturer combining various items into a single package is engaged in a manufacturing activity. Any one of the following factors is not considered conclusive evidence of a manufacturing activity:

(a) The ingredients are purchased from various suppliers;

(b) The manufacturer combining the ingredients attaches his or her own label to the resulting product;

(c) The ingredients are purchased in bulk and broken down to smaller sizes;

(d) The combined product is marketed at a substantially different value from the selling price of the individual components; and

(e) The manufacturer combining the items does not sell the individual items except within the package.

The manufacturer must request certification from the energy program that its product, such as a module, or wind turbine or tower, qualifies as made in Washington.

(1) Manufacturer's statement. The manufacturer must supply the energy program with a statement specifying what processes were carried out in Washington state to qualify the product.

(2) Penalty of perjury. The manufacturer's statement must be made under penalty of perjury.

(3) Field visit to view manufacturing process. The energy program performs a field visit to view the manufacturing process for the product, which may also include, but is not limited to:

(a) An inspection of the process by an engineer or other technical expert;

(b) Testing and evaluation of a product pulled off the production line;

(c) Review of purchase invoices to verify the vendor sources for the parts used in the manufacturing of the product;

(d) Inspection of the production line; and

(e) Requests for clarification concerning questions, if any, discovered during the inspection.

(4) Approval or disapproval of manufacturer's certification. Within thirty days of the field visit, the energy program issues a written decision to the manufacturer on its product's qualification as made in Washington state. The energy program makes the decision available to the public.

(5) Change in manufacturing process. The manufacturer must notify the energy program of any change in the manufacturing process for previously certified products within ten days of such a change.

(6) Inspection of previously certified product's manufacturing process. The energy program reserves the right to perform an inspection of the manufacturing processes for each product, such as a solar module, or a wind tower or turbine, that has been previously certified as manufactured in Washington state. The inspection is conducted to verify that the product continues to qualify as manufactured in Washington state.

(7) Denial or revocation of approval of certification. The energy program may revoke the approval of certification that a product, such as a module, or a wind turbine or tower, is made in Washington state when it finds that the product does not qualify for certification as manufactured in Washington state.

(8) The appeal provisions under Part VII of this chapter apply here.

(9) Document retention. The manufacturer must retain the documentation of the made in Washington certification process for five years after the application period for the related incentive program closes.

Yes. Incentive payments may only be made for kilowatt-hours generated on or after July 1, 2017, and for the following eight years, or until cumulative incentive payments for electricity generated by the project reach fifty percent of the total system price, including applicable sales tax, whichever occurs first.

(1) Authorization of incentive payments. No incentive payments may be authorized or accrued until the final electrical inspection and executed interconnection agreement are submitted to the energy program.

(2) Certification is valid for the incentive program term. This certification entitles the person, business, or household to receive incentive payments for electricity generated from the date the renewable energy system commences operation, or the date the system is certified, whichever date is later.

(3) Changes to incentive rates. Incentive rates determined by certification date may not be retroactively changed except to correct errors that were made during the original application or certification process and that are discovered later.

(4) Incentive schedule. Incentives are issued based on the gross kilowatt-hours generated during the fiscal year beginning on July 1st and ending on June 30th. For the last year of incentive payments, the payment is the balance of the last year of generation less the first year of generation. A negative balance for the last year results in nonpayment.

(5) Certification date. Certification date is determined by the date when the energy program completes its review of a submitted application. However, due to the timing of this program, the following administrative processes apply:

(a) For applications submitted from July 1, 2017, to December 31, 2017:

(i) For purposes of systems that commenced operation on or after July 1, 2017: The certification date is assigned based on the date that the local jurisdiction issued its final approval of the electrical inspection of the renewable energy system.

(ii) For purposes of systems that commenced operation before July 1, 2017: The certification date is assigned as July 1, 2017.

(b) For applications submitted on or after January 1, 2018: The certification date is assigned on the date when the energy program completes its review of a submitted application. The energy program encourages customer-owners to submit all applications on the date the local jurisdiction issues its final approval of the electrical inspection of the renewable energy system. In instances where the certification date might follow the final electrical inspection by more than thirty days, the customer-owner or the serving utility must provide additional information to ascertain the correct initial electrical generation amount to use in calculating the first year of incentive payments.

(1) Customer-owners or administrators receiving incentive payments must keep and preserve, for a period of five years after the receipt of the last incentive payment from the utility, suitable records as may be necessary to determine the amount of incentive received.

(2) Examination of records. Such records must be open for examination at any time upon notice by the energy program.

In determining if a community solar or shared commercial solar project is within the applicable limit when more than one community solar or shared commercial solar project is located on one property, the energy program treats each project's system as separate from the other projects if there are separate production meters and separate certification applications have been submitted to the energy program.

The nonpower attributes of the renewable energy system belong to the utility customer who owns or hosts the system or, in the case of a community solar project or a shared commercial solar project, the participant. The attributes may be kept, sold, or transferred at the utility customer's discretion unless, in the case of a utility-owned community solar or shared commercial solar project, a contract between the customer and the utility clearly specifies that the utility retains the attributes.

If a person, business, or household purchases a property that has a renewable energy system certified in the renewable energy system incentive program, the new customer-owner must (at a minimum) notify the energy program of the transfer of ownership and provide an executed interconnection agreement with the utility serving the premises.

The administrator of a community solar project or shared commercial solar project must provide notice to the energy program of any changes or transfers in project participation.

The reapplication for continued incentive payments through June 30, 2020, must be submitted to the energy program by April 30, 2018. This reapplication must contain, but is not limited to, the following information as specified in the applicant and eligibility requirements in WAC 458-20-273:

(1) The name and address of the applicant and location of the renewable energy system;

(2) The applicant's tax registration number;

(3) The utility name and utility account number;

(4) System information, including system component details and operation data such as global positioning system coordinates, tilt, estimated shading, and azimuth, as applicable;

(5) A signed statement that the applicant understands that this information is true, complete, and correct to the best of their knowledge and belief under penalty of perjury; and

(6) A signed statement authorizing the energy program and the serving utility to share information related to issuing annual incentive payments, including application details and energy generation.

No. If the applicant's renewable energy system has already been certified by the department of revenue for cost recovery incentives, that system is ineligible for the new incentive program.

The person, business, or household may not increase the capacity of a department of revenue-certified system to receive additional cost recovery program incentive payments.

No. There is no fee for reapplication for a department of revenue-certified renewable energy system.

(1) The energy program may take four different types of actions that may result in a right to an appeal:

(a) Denying a system's precertification or certification;

(b) Revoking a system's precertification or certification;

(c) Denying a manufacturer's statement of a product as qualifying as made in Washington state; and

(d) Revoking a previously approved certification of a product qualifying as made in Washington.

(2) The same appeal procedures apply to all four types of action. All appeals involving the renewable energy system incentive program in this chapter are conducted as formal adjudicative proceedings under RCW 34.05.413 through 34.05.476 and chapter 10-08 WAC.

(3) The notice issued by the energy program provides an explanation of the reasons for the denial or revocation, and advises the recipient about how to appeal the decision if the recipient disagrees.

(4) The energy program's action is final unless the recipient files an appeal petition with the energy program within thirty days of service (receipt) of the notice of the energy program's action. RCW 34.05.010(19) defines "service" and includes service by postal mail, electronic mail, and personal service.

For both a denial of an application for certification and a notice of intent to revoke a previously approved certification, the presiding officer of a formal adjudicative proceeding is the Washington state office of administrative hearings. The presiding officer makes the final decision and enters a final order as provided in RCW 34.05.461 (1)(b).

RCW 34.05.470 governs petitions for reconsideration. Petitions for reconsideration must be addressed to or delivered to the presiding officer at the address provided in the final order. The petition for reconsideration must be filed and served as required by WAC 10-08-110.

Judicial review of the final order of the presiding officer is governed by RCW 34.05.510 through 34.05.598.
