N-225B Substation: 115 kV Electrical Infrastructure in the United States

N-225B is an operational electrical substation located in the United States, with coordinates near Sunnyvale, California. The facility operates at a voltage of 115 kV, placing it in the sub-transmission or distribution voltage class typical for serving industrial and residential areas. As a substation in the United States, N-225B operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC) for reliability standards. Substations at this voltage level are critical for stepping down power from higher transmission voltages and distributing electricity to local grids, often incorporating automation per standards like IEC 61850. The substation's location in the Silicon Valley region underscores its importance in supporting a high-density technology and industrial area. Its operational status ensures continued grid stability and power delivery to surrounding communities, contributing to the resilience of the local electrical infrastructure.

The substation is situated in an urbanized area of California, where electrical infrastructure must balance reliability with environmental considerations such as land use and electromagnetic field management. The 115 kV voltage level indicates a moderate footprint, with typical mitigation measures including vegetation management and equipment noise control to minimize local impact.
