[ Docket No. UE-051106 -- Filed August 12, 2005, 1:50 p.m. ]

Subject of Possible Rule Making: Consider establishing regulations to govern the interconnection of consumer-owned power generation facilities to utility delivery facilities. Such regulations may 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.

Statutes Authorizing the Agency to Adopt Rules on this Subject: RCW 80.01.040 and 80.04.160.

Reasons Why Rules on this Subject may be Needed and What They Might Accomplish: RCW 80.28.025 establishes a state policy to encourage electric power resources from renewable sources through use of incentives.

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 light and power businesses serving 80% 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 would constitute substantial progress toward meeting the threshold condition established by SSB 5101 for customer incentive payments. In addition, a rule would establish uniformity among the investor-owned utilities regarding technical and process standards as well as safety and liability standards for such interconnections.

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.

Other Federal and State Agencies that Regulate this Subject and the Process Coordinating the Rule with These Agencies: The Federal Energy Regulatory Commission (FERC) regulates interconnection of generation facilities to transmission facilities used to transmit power in interstate commerce. FERC is finalizing regulations governing interconnection to FERC-jurisdictional facilities. These regulations may provide a model for regulations in Washington state.

Process for Developing New Rule: Agency study; and the commission will ask for initial written comments, and may provide the opportunity for participation in workshop-style sessions as well as opportunities for additional comments.

Interested parties can participate in the decision to adopt the new rule and formulation of the proposed rule before publication by contacting the Secretary, Washington Utilities and Transportation Commission, P.O.
