Overview
Marble Substation is an operational electrical substation in the United States, operated by Illuminating Company. It operates at 138 kV, serving the local grid.
Marble Substation is an operational electrical substation located in the United States, specifically near coordinates 41.651307, -81.408307. The facility is owned and operated by Illuminating Company and operates at a voltage of 138 kV, placing it in the medium-to-high voltage range typical for distribution and sub-transmission substations. The substation 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 a 138 kV facility, it likely plays a role in stepping down transmission voltages for local distribution or interconnecting regional grids. The equipment likely includes circuit breakers, transformers, and switchgear compliant with IEEE standards. This substation supports grid stability and electricity delivery to surrounding communities. Its location in Ohio, a state with a mix of industrial, commercial, and residential demand, underscores its importance in maintaining reliable power supply. The facility's operational status indicates ongoing contribution to the regional electrical infrastructure.
Environmental context
The substation is situated in a region with a temperate climate, where seasonal temperature variations can affect equipment performance and maintenance schedules. Urban or suburban surroundings may influence electromagnetic field considerations and land use. The facility's design likely includes measures to minimize environmental impact, such as oil containment for transformers and noise mitigation.
