Overview
Crocker Sub is a 69 kV substation operated by NIPSCO in Indiana, United States. It plays a role in the regional electrical grid serving local communities.
Crocker Sub is an electrical substation located in Indiana, United States, and operated by NIPSCO (Northern Indiana Public Service Company). The facility operates at a voltage of 69 kV, which places it in the sub-transmission or distribution voltage range, typical for serving industrial, commercial, and residential loads in the region. As part of NIPSCO's network, Crocker Sub is subject to regulatory oversight by the Federal Energy Regulatory Commission (FERC) and must comply with North American Electric Reliability Corporation (NERC) reliability standards. Substations of this voltage level are critical for stepping down power from higher transmission voltages and ensuring stable distribution to end users. The facility's location in Indiana places it within the footprint of the Midcontinent Independent System Operator (MISO) regional transmission organization. The substation's operational status indicates it is actively serving the grid. Its role in the local electrical infrastructure supports the reliability of power supply in the surrounding area. Typical substations of this type include switchgear, transformers, and protection systems to manage power flow and maintain grid stability.
Environmental context
The substation is located in a region with a mix of urban and rural areas. Its operation involves electromagnetic fields and potential oil spill risks from transformers, which are managed through standard environmental safeguards. Typical substations are designed with containment measures to prevent environmental contamination.
