Overview
Ellington is an operational electrical substation in the United States, handling voltages of 138 kV and 3.45 kV. It plays a key role in local grid stability and power distribution.
Ellington is an operational electrical substation located in the United States, with coordinates 44.387466, -88.558406. The facility operates at voltage levels of 138,000 V (138 kV) and 3,450 V (3.45 kV), indicating it serves both transmission and distribution functions. As a substation, it is a critical node in the electrical infrastructure, stepping down high-voltage power for regional consumption. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards for bulk power system stability and FERC oversight for interstate transmission. The 138 kV voltage level is typical for subtransmission or distribution substations, supporting industrial, commercial, and residential loads. The inclusion of a 3.45 kV circuit suggests local distribution to smaller consumers or specialized equipment. Ellington's location in Wisconsin places it within a region with a mix of urban and rural demand. The substation contributes to grid resilience by enabling voltage regulation and fault isolation. Its operational status ensures continued service to the surrounding community, supporting economic activity and daily life.
Environmental context
The substation is situated in a region with a temperate climate, where seasonal weather variations can impact grid operations. The facility's voltage levels and location suggest it serves a mix of residential and light industrial areas. Proper maintenance of switchgear and transformers is essential to minimize environmental risks such as oil leaks or SF6 emissions, which are common concerns for aging electrical infrastructure.
