Star Lake Substation: 138 kV Electrical Substation in the United States

Star Lake Substation is an operational electrical substation located in the United States, managed by Wolverine Power Supply Cooperative. The facility operates at a voltage of 138 kV, placing it within the sub-transmission voltage range typical for regional power distribution. As a substation, it plays a critical role in stepping down transmission-level voltages for local distribution or interconnecting generation sources. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the bulk power system. The 138 kV voltage level is common for sub-transmission networks in the United States, often serving industrial loads or connecting to distribution substations. The facility's equipment likely includes circuit breakers, transformers, and switchgear compliant with IEEE and ANSI standards. Located in a rural area of Michigan, the substation supports the electrical infrastructure for the surrounding community. Wolverine Power Supply Cooperative is a generation and transmission cooperative, and this substation likely serves as a key node in their network, ensuring reliable power delivery to member cooperatives. The facility's operational status and voltage level indicate its importance to regional grid stability.

The substation is situated in a rural area of Michigan, where the local environment includes forests and agricultural land. Electrical infrastructure in such settings typically requires careful siting to minimize visual impact and avoid sensitive habitats. The 138 kV voltage level suggests moderate electromagnetic field emissions, which are managed through standard setback distances and shielding practices. The facility's operation contributes to the regional power supply, supporting local communities and industries.
