Renovation of a power facility in Issaquah, Washington. Completed plans call for the renovation of a power facility.

The City of Issaquah, Washington is soliciting proposals from interested companies to assist the City of Issaquah in installing a maximum 64.2 kW DC, 60 kW AC roof mounted solar PV system at Pickering Barn. The City has a completed feasibility study to the 30% design level and which includes a power one-line diagram, helioscope solar model, concept plan, and solar PV panel, and inverter equipment basis of design specifications. Additionally, the City completed a stamped structural engineering analysis in May 2025. In partnership with the City of Issaquah, the selected company will complete 100% design, and install the final designed solar system and battery storage system at Pickering Barn. Funds for this project come from the Issaquah Sustainability Fund and Puget Sound Energy. The City anticipates applying for direct pay of federal solar tax credits for the system based on a balance of system costs established after project completion. Question Deadline 07/02/2025 at 4:30 PM PT The City of Issaquah hereby gives public notice that it is the policy of the City to assure full compliance with Title VI of the Civil Rights Act of 1964, as amended, the Civil Rights Restoration Act of 1987, Executive Order (E.O.) 12898, and related statutes and regulations in all programs and activities. The City seeks to reduce greenhouse gas emissions from energy consumption in the built environment by building out renewable energy infrastructure where feasible at City facilities. Generate and store renewable energy (OV 2.5) The scope of work generally includes all aspects of installing and interconnecting a 64.2 kW DC, 60 kW AC roof mounted solar P\Z system at Pickering Barn in line with the prepared designs (Appendix B). More specifically the scope of services by the service provider includes, but may not necessarily be limited to: Bring the design documents from 30% design to 100% design for permitting; Coordination with City and utility, Puget Sound Energy, on permitting, site preparation and protection, and installation, informing the City on site power requirements and mounting standards, leading permit applications and interconnection applications, and other needs as necessary for a complete installation; Furnishing solar P\Z and inverter equipment and materials as specified by the contractor's final system design; All aspects of installation of the solar P\Z system including site preparation and protection, rooftop mounting, running of conduit, and electrical interconnections; Testing, commissioning, and maintenance training of the solar P\Z system; Furnishing all documentation requested by the City to submit a timely direct pay claim of the federal energy tax credits. Solar PV System Design, Permitting, and Installation o Final design and permit drawings for rooftop solar PV array. o Provide submittal packages showing electrical, structural, product datasheet, and equipment elevations for the City's review and approval. o Installation is expected for a roof mounted 64.2 kW DC, 60 kW AC solar PV system at Pickering Barn as laid out by the 30% system design in Appendix B. o Provide a minimum warranty of 10 years for the solar product o Ensure that all work as it pertains to site preparation, solar panels, inverters, system mounting, signage, electrical upgrades, and electrical interconnections is installed: Coordinate the installation activities with the solar PV equipment manufacturer, roofing contractor, City staff, Puget Sound Energy, and any subcontractors needed to complete the work; Coordinate with Puget Sound Energy for system interconnection, and to maximize net metering benefits; Coordinate with City staff on appropriate staging areas for equipment that do not interfere with landscaping, parking, or events; Coordinate with City staff for periodic site visits and regular project updates during the design, construction, and installation process; Coordinate with City staff on direct pay tax credit submissions; The contractor shall warrant all civil work performed as part of the installation. If any portion of the civil work is determined to be defective or unsatisfactory by the City or its consultant, the contractor shall, at no additional cost to the City, correct the work to meet applicable standards. Solar PV system requirements o Modules: Installation of 132 490-watt Silfab Solar Inc (or equivalent) panels resulting in a system size of 64.2 kW-DC capacity. o Inverters: Sol-Ark Split Phase (240/120V) inverters as a basis of design. The inverter total nameplate capacity should be 60 kW-AC (minimum). The proposed area for the inverters is on the west side of the building outside close to the electrical room. o Mounting: IronRidge XR Flush Mount racking system that minimizes roof penetrations. Roof penetrations should be done in coordination with the City of Issaquah Administrative Services team and in coordination with the roofing company to ensure no negative impacts on the site. o To maintain the roof system warranty, the selected contractor shall coordinate with and utilize Garland Company, Inc. for the installation of the solar PV racking system to the extent necessary. This includes utilizing Garland Co for the flashing of roof penetrations. This requirement is non-negotiable and intended to ensure the system is installed per the original roof system designer's recommendations and warranty terms. Proposers should include this coordination in their work plan and budget. o Conduit: solar array DC home runs. Conduit should run from the array sections back to the solar inverters at ground level. Lighting, Signage and Security Measures: Selected company must ensure solar P\Z equipment is accompanied by the appropriate supportive infrastructure. The selected company will: o Work with the City to determine appropriate signage and security measures for solar P\Z equipment. o Ensure any lighting on the solar P\Z equipment or its accompanying hardware is compliant with city outdoor lighting codes. o Coordinate with the City and fire code official to clearly identify roof access pathways and tie in points for safety. This includes a strong preference for project construction beginning by October 20, 2025. Full project completion, including commissioning is, not to exceed 12 months.
