Washington § 80.04.550

• Jurisdiction: Washington
• Title 80: PUBLIC UTILITIES
• Ch. 80.04: REGULATIONS—GENERAL

Text

(1) It is the intent of the legislature to exempt from commission regulation thermal energy companies in operation or under development before July 1, 2025, and combined heat and power facilities that are not otherwise regulated under this title. Nothing in this section shall prevent the commission from issuing or enforcing any order affecting combined heat and power facilities owned or operated by an electrical company that are subsidized by a regulated service.

(2) Nothing in this title shall authorize the commission to make or enforce any order affecting rates, tolls, rentals, contracts or charges for service rendered, or the adequacy or sufficiency of the facilities, equipment, instrumentalities, or buildings, or the reasonableness of rules or regulations made, furnished, used, supplied, or in force affecting any:

(a) Thermal energy company operating a thermal energy system that has less than five independent customers and less than 250 residential end users, unless the thermal energy company chooses to opt-in to commission regulation by providing the commission with a request to opt-in to regulation in writing.

(i) For the purposes of this section, "independent customer" means a unique direct customer receiving thermal energy for one or more buildings through one or more metered services.

(ii) For the purposes of this section, "residential end user" means a household in a dwelling unit that is not a direct customer of a thermal energy company but is located within a residential multifamily building or residential portion of a mixed-use building served by a thermal energy company.

(iii) If a thermal energy company's exempted thermal energy system grows to have five or more independent customers and 250 or more residential end users, the thermal energy company must submit the thermal energy system to the commission in a general rate case filing no later than 12 months after surpassing the exemption threshold so the commission can set the rates and charges of the thermal energy company;

(b) Thermal energy company owning and operating any thermal energy system in operation before July 1, 2025, unless the thermal energy company chooses to opt-in to commission regulation by providing the commission with a request to opt-in to regulation in writing;

(c) A combined heat and power facility engaged in thermal energy services, unless such a facility chooses to opt-in to commission regulation by providing the commission with a request to opt-in to regulation in writing.

(3) A thermal energy company that chooses to opt-in to commission regulation must remain under commission regulation and cannot subsequently opt-out of commission regulation.

(4) A thermal energy company that owns a thermal energy system that is under development but has not commenced operation as of July 1, 2025, is not subject to commission regulation if the thermal energy company notifies the commission in writing of the company's plans to operate the thermal energy system.

(5) The legislature finds that gas companies maintain their priority for developing thermal energy network pilot projects as provided in RCW 80.28.460 .

Finding — Intent — 2015 3rd sp.s. c 19: See note following RCW 39.35.010 .

Findings — 1996 c 33: "(1) The legislature finds:

(a) The Washington utilities and transportation commission has the authority to regulate district heating suppliers on the basis of financial solvency, system design integrity, and reasonableness of contract rates and rate formulas under *chapter 80.62 RCW;

(b) Consumers have competitive alternatives to thermal energy companies for space heating and cooling and ancillary services;

(c) Consumers have recourse against thermal energy companies for unfair business practices under the consumer protection act; and

(d) Technology and marketing opportunities have advanced since the enactment of *chapter 80.62 RCW to make the provision of cooling services, as well as heating services, an economical option for consumers.

(2) The legislature declares that the public health, safety, and welfare does not require the regulation of thermal energy companies by the Washington utilities and transportation commission." [ 1996 c 33 s 1 .]

*Reviser's note: Chapter 80.62 RCW was repealed by 1996 c 33 s 3 .
