Overview
St. Paul Substation is an operational electrical substation in the United States, operating at 115 kV. It plays a role in regional grid stability and power distribution.
St. Paul Substation is an operational electrical substation located in the United States, with coordinates 41.199893, -98.461813. The facility operates at a voltage of 115 kV, placing it in the medium-to-high voltage range typical for sub-transmission and distribution substations. This voltage level is critical for stepping down power from high-voltage transmission lines to lower voltages for local distribution. 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. As a 115 kV facility, it likely adheres to NERC's Critical Infrastructure Protection (CIP) standards and may be subject to regional reliability entity oversight. The substation's equipment, including switchgear and transformers, is typical for this voltage class, with automation potentially following IEC 61850 standards. Located in a rural area of Nebraska, St. Paul Substation supports agricultural and residential electricity needs. Its operational status ensures continued grid connectivity for the surrounding community. The facility's role in the local power network contributes to the reliability of electrical infrastructure in the region, serving as a key node for power distribution.
Environmental context
The substation is situated in a rural agricultural region of Nebraska, where the primary environmental considerations include land use compatibility and potential impacts on local wildlife. The 115 kV voltage level indicates moderate electromagnetic field emissions, which are managed through standard siting practices. The facility's operation is subject to environmental regulations under the National Environmental Policy Act (NEPA) and state-level requirements for substation construction and maintenance.
Frequently asked questions
