Overview
Chateau Substation is an operational electrical substation in Wisconsin, United States, owned and operated by Adams-Columbia Electric Cooperative. It operates at 69 kV, serving the local distribution grid.
Chateau Substation is an electrical substation located in Wisconsin, United States, owned and operated by Adams-Columbia Electric Cooperative. The facility is operational and serves as a node in the regional power distribution network, stepping down transmission-level voltage for local consumption. The substation operates at a voltage of 69 kV, which is typical for sub-transmission or primary distribution in rural cooperative systems. As part of the Adams-Columbia Electric Cooperative network, it supports reliable electricity delivery to member-owners in central Wisconsin. The facility adheres to North American Electric Reliability Corporation (NERC) reliability standards and is subject to Federal Energy Regulatory Commission (FERC) oversight for interconnection and wholesale power transactions. This substation plays a critical role in maintaining grid stability for the surrounding agricultural and residential communities. By transforming voltage levels and providing switching capabilities, it enables efficient power distribution and helps integrate distributed energy resources. Its operational status ensures continued service to the cooperative's members, supporting local economic activity and quality of life.
Environmental context
The substation is located in a rural area of Wisconsin, characterized by agricultural land and scattered residential developments. Its 69 kV voltage level indicates it is part of the sub-transmission network, which typically has lower environmental impact than high-voltage transmission lines. The facility's design includes standard measures to contain potential oil spills from transformers and minimize electromagnetic field exposure. Its rural siting reduces proximity to sensitive habitats, though it may still intersect with local wildlife corridors.
Frequently asked questions
Chateau Substation is located in Wisconsin, United States, at coordinates 43.817068, -89.481344. It is owned and operated by Adams-Columbia Electric Cooperative.
Chateau Substation operates at 69 kV (69,000 volts), which is typical for sub-transmission or primary distribution in rural electric cooperative systems.
Chateau Substation is owned and operated by Adams-Columbia Electric Cooperative, a member-owned utility serving central Wisconsin.
Substations in the United States must comply with NERC reliability standards for grid stability and FERC regulations for wholesale electricity markets. Additionally, they follow IEEE and ISO/IEC 61850 standards for substation automation and protection.
A 69 kV substation typically serves as a sub-transmission node, stepping down higher transmission voltages (e.g., 138 kV) to distribution levels (e.g., 12 kV) for local delivery to homes and businesses. It also provides switching and protection functions to maintain grid reliability.
