Overview
Rosholt CEC is an operational electrical substation in Wisconsin, United States, operating at 69 kV. It plays a role in local grid stability and power distribution.
Rosholt CEC is an operational electrical substation located in Wisconsin, United States. With a voltage level of 69 kV, it is classified as a medium-voltage substation, typically serving regional distribution networks rather than high-voltage transmission. The facility is part of the broader U.S. electrical infrastructure, which is regulated by NERC reliability standards and FERC oversight for grid stability. Operating at 69 kV, this substation likely steps down power from higher transmission voltages for local distribution or interconnects with nearby generation sources. In the U.S., substations of this scale are common in rural and suburban areas, supporting residential, agricultural, and small industrial loads. The regulatory framework ensures compliance with NERC standards for reliability and cybersecurity, while state-level public utility commissions oversee local rate and service quality. The substation's location in central Wisconsin places it within a region characterized by mixed agricultural and forested landscapes. Its role in the grid is critical for maintaining voltage stability and power quality for the surrounding communities. As part of the interconnected Eastern Interconnection, Rosholt CEC contributes to the resilience of the regional power system, especially during peak demand or extreme weather events.
Environmental context
The substation is situated in a rural area of Wisconsin, where the surrounding landscape includes farmland and woodlands. Substations like Rosholt CEC typically have a localized environmental footprint, primarily related to electromagnetic fields and potential oil leakage from transformers. The 69 kV voltage level is moderate, reducing the extent of right-of-way clearing compared to higher-voltage lines. The facility's operation supports the integration of renewable energy sources, such as wind and solar, which are increasingly common in the region.
Frequently asked questions
Rosholt CEC is located in Wisconsin, United States, near the town of Rosholt. Its approximate coordinates are 44.656891 N, -89.286456 W.
Rosholt CEC operates at 69 kV, which is a medium voltage level commonly used for subtransmission and distribution in the United States.
Rosholt CEC is currently operational, meaning it is actively serving the electrical grid.
In the United States, substations like Rosholt CEC must comply with NERC reliability standards for grid stability and FERC regulations for interstate transmission. Additionally, state-level public utility commissions oversee local distribution.
A 69 kV substation typically steps down power from higher transmission voltages (e.g., 138 kV or 230 kV) for local distribution to residential, commercial, and industrial customers. It may also interconnect with distributed generation sources.
