Lake Lillian Substation - Operational Electrical Substation in the United States

Lake Lillian Substation is an operational electrical substation located in the United States, with coordinates 44.935606, -94.900471. The facility operates at voltage levels of 69 kV and 12.47 kV, indicating a role in both sub-transmission and distribution within the electrical grid. As a substation in the United States, this facility operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC) for transmission-level assets. The 69 kV voltage level typically serves as a sub-transmission voltage, connecting bulk power systems to distribution networks, while the 12.47 kV level is common for primary distribution to end users. The substation's location in a rural area of Minnesota suggests it may serve agricultural and small community loads, contributing to grid stability and reliability in the region. Its operational status ensures continued support for local electricity needs, with potential integration into broader regional transmission networks.

The substation is situated in a rural area of Minnesota, characterized by agricultural land and small communities. The environmental context includes potential impacts from electromagnetic fields and the need for vegetation management to maintain clearance around equipment. The facility's operation supports grid stability, which is critical for integrating renewable energy sources like wind and solar that are prevalent in the region.
