Preble Substation - 138 kV Electrical Substation in the United States

Preble is an electrical substation located in the United States, with coordinates 44.505694, -87.970120. The facility operates at a voltage of 138 kV, classifying it as a high-voltage substation critical for transmission and distribution within the regional power grid. As an operational substation, it supports the reliable delivery of electricity to surrounding areas. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards and FERC oversight for transmission-level assets. At 138 kV, Preble is typical of medium-to-high voltage substations that interconnect local distribution networks with the broader transmission system. Such facilities often employ technologies like circuit breakers, transformers, and switchgear to manage power flow and ensure grid stability. Preble's location in the United States places it within a well-regulated electrical infrastructure sector. The substation contributes to the resilience of the local grid, serving communities and industries in its vicinity. Its operational status ensures ongoing support for electricity demand, and its voltage level indicates a role in both local distribution and regional transmission coordination.

The substation's location in the United States involves compliance with environmental regulations related to electromagnetic fields, oil containment from transformers, and land use. As a 138 kV facility, it typically requires buffer zones and may impact local wildlife corridors. The site's rural or suburban setting influences its environmental footprint, with considerations for stormwater management and vegetation maintenance to prevent outages.
