National Marine Fisheries Service (NMFS) Northwest Fisheries Science Center (NWFSC) Point Adams Electrical Backup Power System

1.0 Project Background & Location. The Northwest Fisheries Science Center (NWFSC) is a marine research organization owned and operated by the U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), National Marine Fisheries Service (NMFS).

NWFSC has five (5) major campuses located in Washington and Oregon with its regional headquarters located in Seattle, WA.

1.1 Project Location: The Point Adams Research Station is located at 520 Heceta Place, Hammond, OR 97121. It was the location of a former U.S. Coast Guard facility in the early to mid-1900s. It is comprised of five major buildings sitting on approximately 5.8 acres, located along the shoreline near the mouth of the Columbia River.

1.2 Current Infrastructure: The Point Adams Main Campus does not have a central electrical backup system. It relies on staff to manually start portable gasoline power generators to energize critical loads during a power outage. Currently, two separate 200-amp single-phase services feed the site from power poles along the west boundary:

1.2.1 One 200-amp service feeds the 4-Bay Building from an overhead pole running west to east.

1.2.2 The second 200-amp service is located in the northwest corner of the site inside the Generator Building.

2.0 Objective: To establish a resilient and unified power infrastructure, the two existing separate utility services shall be consolidated into a single central service entry point for the campus. The consolidated service will establish a single point of utility interconnection supplying a 400-amp, 120/240V single-phase system with emergency battery backup capacity and integration capability for solar photovoltaic (PV) generation to increase resilience and reduce carbon emissions.

2.1 Order of Precedence: This SOW establishes the primary functional, technical, and performance requirements for the project. In the event of any conflict between this SOW and attached technical specifications referenced in Section 8 of this SOW, the terms and requirements of this SOW shall govern.

3.0 Technical Scope of Work. The contractor shall provide all required design, service, labor, parts, equipment, tools, and materials to complete the tasks described below. All work shall comply with applicable federal, state, local codes, and local electrical utility requirements (Pacific Power / PacificCorp).

3.1 TASK 1 – Electrical Utility Service Consolidation. The contractor shall perform all required work including new electrical panels, metering, high-voltage, low-voltage, and conduit systems to consolidate utility power:

3.1.1 Service Consolidation: Combine the two existing independent 200-amp utility services into a single 400-amp, 120/240-volt single-phase meter/main utility service entry supplying two 200-amp distribution panels.

3.1.2 Conduit Utilization: Utilize the existing empty 4-inch Schedule 40 underground feeder conduits installed in 2024, as indicated by the red lines on Figure 1 of Exhibit A.

3.1.3 Distribution Hierarchy: Build out the single-line distribution architecture as shown in Figure 8.1 of Exhibit A and Figure 8.2 of Exhibit A

3.1.3.1 Main Distribution: The single 400A single-phase service feeds a central 400A Main Distribution panel.

3.1.3.2 Branch Feeders: Route and connect three distinct feeder circuits from the 400A Main Distribution panel:

3.1.3.2.1 One 60A Feeder to the 2-Bay Building Panel.

3.1.3.2.2 One 200A Feeder to the Main Building Panel.

3.1.3.2.3 One 200A Feeder to the 4-Bay Building Panel.

3.1.3.3 Downstream Sub-Feeder: Install a 150A Sub-feed originating from the 4-Bay Building Panel to feed the 1-Bay Building Panel.

3.1.4 Component Restrictions: Brand references in design documents represent basis-of-design standards; equal or superior alternatives are acceptable upon review. All products must comply with the Buy American Act. Made-in-China products or components will not be accepted.

3.2 TASK 2 – Inverters and Battery Backup System with Remote Load Control. This is a mandatory design-build task to design, furnish, and install an intelligent hybrid inverter and battery energy storage system (BESS) capable of providing emergency power for a minimum of 72 hours for essential site functions. The installation must implement the microgrid architecture and sequence of operations detailed in Figure 8.2 of Exhibit A:

3.2.1 Microgrid & Islanding Capabilities: The 200-amp distribution panels supplying the Main Building and 4-Bay Building must operate both in parallel with the utility grid and as an islanded microgrid during power outages. To enable this, integrate a service-rated, UL-listed Microgrid Interconnection Device (MID / Backup Isolation Transfer Device) that automatically isolates the facility from the grid during outages.

3.2.2 Power Conversion & Inverters: Power conversion and backup shall be delivered by split-phase hybrid inverter/chargers with sufficient continuous islanded capacity and motor-surge headroom.

Inverter AC outputs must land on their respective panels via code-compliant circuit breakers and use utility AC for battery charging when grid power is present. Neutral-to-ground bonding must automatically shift so the bond resides at the main service under grid conditions and at the inverter system when islanded.

3.2.3 Smart Load Management: To minimize battery capacity requirements while achieving the 72-hour resiliency target, the system must automatically isolate and shed non-critical loads during an outage. The system shall utilize remotely controlled breakers, load-control relays, or smart load-shedding panels (e.g., Powerlink Panel Boards) controlled by a central Backup Controller.

3.2.4 Load Classification: The contractor shall coordinate with NOAA operations staff to finalize load classifications:

3.2.4.1 Critical Loads (Must remain continuously powered): Freezers located in or near the 1-Bay

Building, indoor/outdoor security and facility lighting, and facility IT/computer network loads.

3.2.4.2 Non-Critical Loads (Automatically shed during grid outages): Comfort HVAC, standard receptacle circuits, water heating, and non-essential plug loads.

3.2.5 Automated Sequence of Operations: The system must execute the exact sequence detailed in Figure 8.2 of Exhibit A:

3.2.5.1 Step 1: Utility grid fails.

3.2.5.2 Step 2: MID opens and the system islands.

3.2.5.3 Step 3: Inverters form the islanded grid and energize the backup bus.

3.2.5.4 Step 4: Non-critical loads are automatically shed via controller signals.

3.2.5.5 Step 5: Critical loads remain powered uninterrupted.

3.2.5.6 Step 6: Solar PV seamlessly charges batteries and supports site loads while islanded.

3.3 OPTIONAL TASK 3 – Solar Panel Installation. Provide and install a ground-mounted 20 kWdc solar photovoltaic (PV) array, including panels, mounting rails, structural framing, wiring, and balance-of-system electrical equipment. This optional task integrates directly into the inverter/battery system as represented in Figure 8.2 of Exhibit A:

3.3.1 Electrical Configuration: Solar generation must be sized to total 20 kWdc and wired as 600 Vdc-class strings into properly configured Maximum Power Point Tracking (MPPT) charge controllers. The controllers shall connect to the battery/inverter system in a DC-coupled topology landing directly on the common 48V battery bus to maintain battery charging capability during grid outages.

3.3.2 Conduit Routing: Utilize the existing underground conduit path running from the Generator Building to the 1-Bay Building.

3.3.3 Safety & Compliance: Include PV/DC disconnects, overcurrent protection, equipment grounding, and module-level rapid-shutdown devices compliant with NEC Article 690 and utility standards.

3.3.4 Structural & Civil Engineering:

3.3.4.1 Structural Framing: Solar panels shall mount on an exterior metal structure engineered for local wind velocity and design pressures.

3.3.4.2 Pier Foundations: Mount structural framing on 16-inch round concrete pier foundations installed to a depth below the local frost line.

3.3.4.3 Footprint: Array footprint requires approximately 1,500 sq. ft. (measuring 25 ft. by 60 ft.).

3.3.4.4 Enclosure & Clearance: Provide a 5-foot clearance around the array and install a 4-foot-high chain-link perimeter fence around the solar installation.
