Overview
Sub 85 is an operational electrical substation in the United States, owned and operated by MidAmerican Energy. It operates at a voltage of 161 kV, serving the regional power grid.
Sub 85 is an operational electrical substation located in the United States, specifically at coordinates 41.470948, -90.662585. Owned and operated by MidAmerican Energy, this facility plays a key role in the regional transmission network. The substation operates at a voltage of 161 kV, which is typical for sub-transmission and distribution-level infrastructure in the U.S. grid. As part of the U.S. electrical infrastructure, Sub 85 operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and security. The substation likely employs modern automation and protection systems, such as those based on IEC 61850, to manage power flow and maintain stability. The substation's location in the Midwest, a region with a mix of urban and rural loads, underscores its importance in delivering reliable electricity to homes, businesses, and industries. Its operational status and voltage level indicate it serves as a critical node in the local grid, supporting the integration of generation sources and maintaining supply-demand balance.
Environmental context
The substation is situated in a region characterized by a temperate climate with seasonal variations. Its location near the Mississippi River may influence local environmental considerations, such as flood risk and soil stability. The facility's design and operation likely incorporate measures to minimize electromagnetic field exposure and ensure safe handling of insulating oils, in compliance with environmental regulations.
