Questions District Background Public Utility District No. 1 of Okanogan County (District) serves the electricity and broadband needs of Okanogan County, the largest county in the state of Washington @ 5315 sq-miles). District formed by voters in 1939 and has a Board consisting of three elected officials serving six year terms on a staggered basis.
In 1945 District completed purchase of Washington Water Power electric system (including Enloe Dam and Power Plant) . TODAY ~100 Employees serving 15,700 customers 104 miles of 115-kV transmission line and 16 substations. 1373 miles of overhead and 437 miles of underground distribution line.
Main electric power sources BPA, Wells Hydro, Nine Canyon Wind Farm Standard and Poors A bond rating; Moodys A1 bond rating Enloe Dam and retired power plant 3 Project Location Project Map
Location Similkameen River 3.5 miles NW of Oroville, WA. A 50 Year FERC License for a 9 MW power plant issued July 2013 . Enloe Dam History Dam and 3.6-MW hydroelectric power plant constructed in 1920s. Power plant decommissioned in 1958 when low-cost electric power from Bonneville System became available. 6 New Power Plant SCOPE New Power
Plant Enloe Dam Modifications Addition of crest gates and outlet works, Power Headworks - New intake channel, power intake, and penstocks on the east bank next to the existing dam, Power Plant - New 9-MW hydroelectric power plant and tailrace channel on east bank of the river downstream of the existing dam, Interconnection - New electric substation and a short interconnection to the Districts existing distribution system. 8 SCOPE New Power Plant SCOPE New Power Plant

Design-Build Agreement 1. Validation Period Validate information from the Owner. Refine owner requirements and project scope. Develop design criteria - Basis of design documents. Innovation and value engineering options. Permitting/Compliance approach. Develop target schedule and budget. Develop GMP, Fixed Price or other price approach. Update schedule Contract amendment. 2. Execution Period Complete permitting in collaboration with District Ongoing regulatory compliance with District. Complete engineering design.
Equipment procurement. Construction. Operation & Maintenance (Optional). Benefits of Design-Build Approach RCW 39.10.280(2)(a) will provide a substantial fiscal benefit Innovation, cost savings and other benefits from value engineering executed by the District/DB team. Cost-risk benefits in allocating design, integration and performance risk to the D-B team.
Alternative financing, operations and maintenance proposal will provide District with significant benefit. RCW 39.10.300(1)(a) The construction activities are highly specialized and a design-build approach is critical in developing the construction methodology Hydro power plant construction requires close collaboration between designer, generating equipment supplier and installation contractor. RCW 39.10.300(1)(b) The projects selected provide opportunity for greater innovation or efficiencies between the designer and the builder Early contractor involvement to address constructability issues, develop practical
construction plans and to finalize environmental plans and protection measures. Integration of design, permitting, procurement and construction of power facilities creates opportunities for innovative and cost-effective solutions. RCW 39.10.300(1)(c) significant savings in project delivery time would be realized Project delivery time reduced by early initiation of equipment procurement and by overlapping final engineering design with equipment procurement and construction.
