OF PROPOSAL Energize Eastside Project PROPONENT Puget Sound Energy (PSE) PROJECT LOCATION The project involves improvements to PSE’s electrical grid in the Eastside area of King County, to address a deficiency in electrical transmission capacity. The area identified by PSE as having a transmission capacity deficiency is situated between Redmond in the north to Renton in the south, and between Lake Washington and Lake Sammamish. The study area goes through the jurisdictions of Redmond, Bellevue, Newcastle, King County, and Renton. PROJECT DESCRIPTION The purpose of the project is to address a projected deficiency in transmission capacity resulting from growth in electrical demand, which could affect the future reliability of electrical service for the Eastside. PSE proposes to construct and operate a major new transformer served by approximately 16 miles of new high-capacity electric transmission lines (230 thousand volts [kilovolts, or kV]) extending from Redmond to Renton. The proposed transformer would be placed at a new substation near the center of the Eastside. Electrical power would be transmitted to this substation and the voltage lowered, or “stepped down” (transformed), from 230 kV to 115 kV for distribution to local customers. PSE has proposed a preferred alignment for the transmission lines, referred to in this Final EIS as “PSE’s Proposed Alignment.” The City of Bellevue is overseeing the Environmental Impact Statement (EIS) process in cooperation with the jurisdictions of Kirkland, Newcastle, Redmond, and Renton (collectively referred to as the Partner Cities). The City of Bellevue is the State Environmental Policy Act (SEPA) nominal Lead Agency. The Energize Eastside EIS is a Phased EIS (Washington Administrative Code [WAC] 197- 11-060(5)). The Phase 1 Draft EIS (released in January 2016) broadly evaluated at a programmatic level the general impacts and implications associated with feasible and reasonable options available to address PSE’s identified objectives for the project. The Phase 2 Draft EIS (released in May 2017) was a project-level evaluation, describing impacts at a project-specific level for a group of potential route segments and options. The project-level Phase 2 Draft EIS incorporated the Phase 1 Draft EIS by reference. Based on the results of the Phase 2 Draft EIS analysis, PSE has refined the proposed route of the transmission lines and associated project components, as evaluated in greater detail in this Final EIS. Although the City of Kirkland is a Partner City, the project-level analysis does not include Kirkland because PSE’s Proposed Alignment for Energize Eastside does not pass within Kirkland city limits.   FINAL EIS     PAGE II    FACT SHEET  MARCH 2018  SUMMARY OF ALTERNATIVES AND OPTIONS No Action Alternative PSE would continue to manage its maintenance programs to reduce the likelihood of equipment failure, and would continue to stockpile additional equipment so that repairs could be made quickly. As appropriate, conductor replacement on existing lines would occur. New 230 kV overhead transmission lines and a new substation would not be constructed. PSE’s Proposed Alignment: New Substation and 230 kV Transmission Lines New Substation Construct a new substation, the “Richards Creek” substation, adjacent to the existing Lakeside substation in Bellevue. New Overhead Transmission Lines Construct approximately 16 miles of new 230 kV overhead transmission lines between the Sammamish and Talbot Hill substations. This would occur entirely within PSE’s existing transmission line corridor connecting these two substations. CONSTRUCTION TIMING FOR THE PROJECT PSE intends to start construction on the new substation and the south portion of the transmission line by the summer of 2018, if possible. This timeframe is based on a projected capacity deficiency that could affect system reliability by that date. After the south portion is completed, construction on the north portion would begin during PSE’s next available construction work window, which is anticipated to be spring of 2019.
