Coloma Substation - 69 kV Electrical Infrastructure in the United States

Coloma is an operational electrical substation located in the United States, with coordinates 44.035662, -89.502972. The facility operates at a voltage level of 69 kV, which classifies it as a medium-voltage substation typically used for subtransmission or distribution within the electrical grid. Substations at this voltage level are critical for stepping down power from high-voltage transmission lines to lower voltages for local distribution. In the United States, substations like Coloma operate under the regulatory oversight of the North American Electric Reliability Corporation (NERC) and are subject to reliability standards that ensure grid stability. The facility's voltage level suggests it may serve a rural or suburban area, connecting bulk power systems to local distribution networks. Typical equipment includes transformers, circuit breakers, and switchgear, often automated with IEC 61850 standards for communication and control. The environmental and operational significance of Coloma lies in its role in maintaining reliable electricity supply to the surrounding region. Substations at this voltage are essential for integrating renewable energy sources and managing load fluctuations. The facility's location in the United States, a country with a highly developed electrical infrastructure, underscores its contribution to the resilience and efficiency of the national grid.

The substation is situated in a region with a temperate climate, which influences equipment design and maintenance schedules. Its voltage level of 69 kV indicates a moderate footprint, with typical environmental considerations including electromagnetic field management and oil containment for transformers. The rural or suburban setting may reduce direct ecological impact compared to urban substations, but land use and vegetation management remain relevant for operational safety and reliability.
