Overview
Walker is an operational electrical substation in Milwaukee, Wisconsin, owned by Wisconsin Electric Power Company. It operates at 138 kV, supporting regional grid stability.
Walker is an operational electrical substation located in Milwaukee, Wisconsin, United States. Owned by Wisconsin Electric Power Company, the facility operates at a voltage of 138 kV, placing it within the medium-to-high voltage range typical for distribution and sub-transmission substations in the region. The substation plays a key role in the local electrical infrastructure, stepping down power from higher voltage transmission lines for distribution to residential, commercial, and industrial customers in the Milwaukee area. As part of the United States electrical grid, Walker operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure reliability and security for bulk power systems. The substation likely incorporates modern automation and protection systems, such as those based on the IEC 61850 standard, to enhance operational efficiency and grid resilience. Wisconsin's electrical infrastructure is characterized by a mix of coal, natural gas, and renewable energy sources, with increasing integration of wind and solar power. The environmental context of Walker includes its urban location in Milwaukee, a major city on the western shore of Lake Michigan. The substation's operation is critical for maintaining grid stability in a densely populated area with significant industrial activity. Its 138 kV voltage level indicates it serves as a key node in the regional transmission network, supporting the delivery of electricity from generating stations to distribution systems. The facility's age and specific equipment details are not publicly available, but its continued operational status suggests ongoing maintenance and upgrades to meet evolving grid demands.
Environmental context
Located in urban Milwaukee, Wisconsin, the Walker substation operates in a region with a mix of industrial, commercial, and residential loads. The 138 kV voltage level indicates its role in sub-transmission, connecting bulk power sources to local distribution networks. The area's proximity to Lake Michigan influences weather patterns, with potential for ice storms and high winds that can affect overhead lines. The substation's design likely includes measures to mitigate environmental impacts, such as oil containment for transformers and noise reduction for nearby communities.
Frequently asked questions
The Walker substation is located in Milwaukee, Wisconsin, United States, at coordinates 43.031902, -87.951077.
The Walker substation operates at 138 kV, which is a common sub-transmission voltage level in the United States.
The Walker substation is owned by Wisconsin Electric Power Company, a major utility serving the Milwaukee area.
Substations in the United States must comply with NERC reliability standards and FERC regulations. Additionally, IEC 61850 is often used for substation automation and communication.
A 138 kV substation typically serves as a sub-transmission node, stepping down voltage from higher transmission lines (e.g., 345 kV) for distribution to local networks, supporting industrial and urban loads.
