Overview
Building 420 is a substation operated by the U.S. Navy in the United States. It supports electrical infrastructure for naval operations in the Pacific Northwest.
Building 420 is an operational substation located in the United States, managed by the U.S. Navy. The facility is situated at coordinates 47.558124, -122.630299, placing it within the Puget Sound region, a key area for naval activities. As a substation, it plays a critical role in distributing electrical power to support military and related infrastructure. Substations of this type typically operate at transmission or sub-transmission voltages, stepping down power for local distribution. The U.S. Navy's ownership indicates the substation likely serves a naval base or support facility, adhering to federal reliability standards and security protocols. In the United States, substations are regulated under NERC reliability standards and FERC oversight for grid interconnection. This substation contributes to the operational readiness of naval installations by ensuring stable power supply. Its location in the Pacific Northwest, a region with a mix of hydroelectric and other generation sources, underscores its role in maintaining energy resilience for critical defense infrastructure. The facility's operational status highlights its ongoing importance to local and national security operations.
Environmental context
The substation is located in a coastal temperate rainforest climate, with high annual rainfall and proximity to Puget Sound. Such environments require robust insulation and corrosion protection for electrical equipment. The site's urban-industrial setting near naval facilities may involve considerations for electromagnetic field management and stormwater runoff control to protect local waterways.
