Overview
Dolton Substation is an operational electrical substation in the United States, operated by East River Electric Power Cooperative. It operates at 69 kV, serving the regional power grid.
Dolton Substation is an operational electrical substation located in the United States, specifically in the region served by East River Electric Power Cooperative. The facility operates at a voltage level of 69 kV, which is typical for sub-transmission and distribution substations that connect local distribution networks to higher-voltage transmission lines. As a substation owned and operated by East River Electric Power Cooperative, Dolton Substation plays a role in the cooperative's mission to provide reliable electricity to its member systems. The cooperative is a generation and transmission (G&T) cooperative that supplies power to distribution cooperatives across South Dakota and Minnesota. Substations like Dolton are critical nodes in the grid, stepping down voltage for local distribution or switching power flows. The facility operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for the bulk power system. As part of the Eastern Interconnection, Dolton Substation contributes to grid stability and power delivery in the region, supporting rural and agricultural communities.
Environmental context
The substation is located in a rural area of the United States, where electrical infrastructure supports agricultural and residential loads. The 69 kV voltage level indicates a sub-transmission role, with potential environmental considerations including electromagnetic fields and land use for rights-of-way. The facility's operation is subject to environmental regulations under the National Environmental Policy Act (NEPA) for any upgrades or expansions.
