Substation #2 Power Upgrade Supplies

The synopsis is not a Request for Quotes (RFQ) or proposals (RFP). This announcement is for information and planning purposes only and is not a commitment by the Government, implied or otherwise, to issue a solicitation or award a contract. Summary of Work: The salient characteristics of the products must meet specifications.

McNary Lock & Dam (MNA) relies on potable water to operate its main unit generators. A 400,000 gallon tank is located on the hill above McNary Dam. Well house pumps are used to maintain the water level and pressure to supply the project. The town site Pump House is currently being used for chlorinating the potable water supplied to the McNary machine shop, warehouses and powerhouse. This water is used for gland systems in addition to potable water. The town site has a dedicated transformer bank to supply power. The construction of the new McNary Dam Potable Water System, adding a 60A breaker for the future load, could impact the existing design load of the town site house. It's recommended to increase the capacity of the transformer bank.

It's the intent of the USACE to procure a new system for sectionalizing, tapping or terminating underground cable and a new 225KVA transformer for the substation to feed the town site house load and the existing 208V /120V, three phase load from well house #2.
