COUNCIL BILL __________________

AN ORDINANCE relating to the City Light Department; amending rates, terms, and conditions for the use and sale of electricity supplied by the City Light Department for 2024, 2025, and 2026; and amending Sections 21.49.020, 21.49.030, 21.49.052, 21.49.055, 21.49.057, 21.49.058, 21.49.060, 21.49.065, 21.49.083, 21.49.085, and 21.49.086 of the Seattle Municipal Code.

WHEREAS, the City Light Department’s Adopted 2025-2030 Strategic Plan Update establishes the amount of total revenue to be collected from customers through rates for 2025 and 2026, which translates to average rate increases of 5.4 percent in both years; and

WHEREAS, the Department has completed a cost of service study that identifies the amount of revenue to be collected from each customer rate class; and

WHEREAS, a report on rate design completed jointly by the Department and the City Light Review Panel, presented to the City Council in 2019 and memorialized in Clerk File 321222, identified near-term priorities to (1) adjust residential block rates to be closer to actual cost and facilitate other rate design concepts, (2) deploy a time-of-use rate option to help manage power demands at peak time and help customers to reduce their costs, and (3) increase basic service charges to reflect the fixed costs associated with serving individual customers; and

WHEREAS, Ordinance 126677 reduced the number of rate schedules for 2023 onward, restructuring rate codes such that customers outside Seattle are served under the same schedule, with changes for franchise differentials, utility taxes, and undergrounding applied based on the jurisdiction in which the customer is located; and

WHEREAS, effective January 1, 2024, the Department implemented a Bonneville Power Administration (BPA) pass-through that increased all per kWh charges by 0.12 cents per kWh without amending the Seattle Municipal Code (SMC), as authorized by SMC 21.49.081; and

WHEREAS, the net wholesale revenue forecast values used for the Rate Stabilization Account mechanism are set at amounts assumed for rates and budget; and

WHEREAS, updates to the Large Solar Program authorized by SMC 21.49.083, now the Large Customer Renewable Generation Program, are needed to reflect growing interest and diversity in large-scale customer-installed generation arrays within the Department’s service territory; NOW, THEREFORE,

BE IT ORDAINED BY THE CITY OF SEATTLE AS FOLLOWS:

C. Large (( solar )) Customer Renewable Generation program customers shall be metered, billed, and credited according to the following provisions:

1. The customer’s two-way advanced meter will measure accumulated kilowatt hours of inbound retail consumption and outbound exported power.

2. Any electricity produced by the customer’s (( solar PV array )) system may be used to reduce inbound retail electricity consumption at the customer’s rate schedule for electric service.

3. Electricity generated in excess of that consumed by the customer may be exported to the Department’s system. Accumulated kWh of exported electricity shall be measured by the advanced meter and each customer will be credited for exported electricity according to the same Large Customer (( Solar )) Renewable Export Rate, which reflects the value of the power and grid benefits.

6. Customers that permit and complete buildings under the terms of the Living Building Pilot outlined in Section 23.40.060, or receive Living Building Challenge certification for a building within City Light service areas outside of Seattle before December 31, 2025, or buildings meeting high energy efficiency standards as determined by the Department, will receive annual net metering as described in Section 21.49.082. The maximum (( solar array )) system allowed under this provision is 250 kW. Affordable housing performing under high energy efficiency standards as determined by the Department may receive net metering for (( solar arrays )) systems up to 500 kW.
