Contract Overview

Solicitation details, issuing organization, response deadlines, documents, and interested companies for this government contract opportunity.

AI Contract Overview

This project involves repurposing an existing 800 KW SPIDERS generator at the JBPHH Wastewater Treatment Plant to provide emergency backup power specifically for the Effluent Pump Station. The EPS requires approximately 600 KW to pressurize the outfall for effluent disposal. This installation serves as a tertiary power source, acting as a fail-safe if both the primary 11.5 KV feeders from the Mamala Substation and the existing 1600 KW backup generator in Building 1699 fail. Maintaining power to the EPS is critical to prevent wastewater spills and ensure compliance with NPDES Discharge Permit requirements. As part of the scope of work, the contractor will demolish and remove unused portions of the original SPIDERS project, including the flow batteries associated with the microgrid, as sanctioned by Utilities Management. The project is managed by Navfac Hawaii under NAICS code 237130. While the generator currently provides backup power to switchgear in Building 1351, the primary objective of this effort is to secure the operational continuity of the effluent pumping process.

Full Description

The scope of work is to connect the existing 800 KW SPIDERS generator currently located at the JBPHH Wastewater Treatment Plant (WWTP, formerly Fort Kamehameha WWTP) to emergency power the JBPHH WWTP Effluent Pump Station (EPS). The Effluent Pump Station (EPS) pressurizes the outfall for the disposal of plant effluent. The EPS estimated electrical load is about 600 KW, so it is assumed that the SPIDERS generator can support operation of the EPS. It is noted that the WWTP primary power to the switchgear that powers the EPS is provided by two 11.5 KV feeders from Mamala Substation and an on-site step-down transformer (Xfmr 1701). If primary power should fail (Basewide power outage), then currently the existing 1600 KW generator in Bldg 1699 activates (via an automatic transfer switch or ATS); note that the 1600 KW generator powers the EPS and other important WWTP processes, such as aeration blowers, recirculation pumps, etc., and thus has a rating higher than 600 KW. Should this 1600 KW generator or its ATS fail, then installation of the 800 KW SPIDERS generator could provide a third backup power source for the EPS; by keeping the EPS running, and since wastewater flows by gravity from the WWTP Headworks (front) to the EPS (no pumping until the wastewater reaches the EPS), only a running EPS is needed to prevent a spill (which is very important from a WWTP NPDES Discharge Permit compliance standpoint). As a part of this project, and sanctioned by Utilities Management (UM), the remaining portion of the SPIDERS project can be and should be removed (demolished); it is no longer used, such as the flow batteries that are part of the SPIDERS microgrid. t should also be noted that the 800 KW SPIDERS generator also currently provides backup power to switchgear located in Bldg 1351; the switchgear in Bldg 1351 powers ...
