First Lake Substation - Xcel Energy 115 kV Substation in the United States

First Lake Substation is an operational electrical substation located in the United States, owned and operated by Xcel Energy. The facility operates at a voltage of 115 kV, placing it in the medium-to-high voltage range typical for distribution and sub-transmission substations. As part of Xcel Energy's infrastructure, it plays a role in the regional power grid. 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. In the United States, substations like First Lake are critical nodes for voltage regulation and power distribution, often equipped with switchgear and transformers to manage electricity flow. First Lake Substation contributes to the stability and reliability of the local electrical grid, serving residential, commercial, or industrial customers in its area. Its operational status ensures continued support for the region's energy needs, aligning with Xcel Energy's commitment to providing reliable electricity service.

The substation is located in a region with a temperate climate, typical of the northern United States. Its operation involves electromagnetic fields and potential noise from transformers, but modern substations are designed to minimize environmental impact. The site's rural or suburban setting reduces proximity to sensitive ecosystems, though standard mitigation measures for oil containment and wildlife protection are likely in place.
