Overview
Oak Grove Graham Substation is an operational electrical substation in the United States, owned and operated by PowerSouth Energy Cooperative. It operates at 115 kV, serving the regional grid.
Oak Grove Graham Substation is an operational electrical substation located in the United States, owned and operated by PowerSouth Energy Cooperative. The facility operates at a voltage of 115 kV, placing it in the medium-voltage range typical for distribution and sub-transmission substations. The substation is part of the broader electrical infrastructure managed by PowerSouth, a generation and transmission cooperative serving Alabama and northwest Florida. As a 115 kV facility, it likely plays a role in stepping down power from higher transmission voltages for local distribution or interconnecting with other grid assets. Operational substations like Oak Grove Graham are critical for maintaining grid stability and reliability. They facilitate voltage regulation and power distribution to residential, commercial, and industrial customers. The facility's location in the southeastern US places it within the regulatory framework of NERC reliability standards and FERC oversight for transmission-level assets.
Environmental context
The substation is located in a rural area of the southeastern United States, near Oak Grove, Florida. The surrounding environment includes mixed forest and agricultural land. Electrical substations in such settings typically have minimal direct environmental impact, though they require vegetation management to maintain clearances and prevent outages. The 115 kV voltage level is common for sub-transmission lines that may traverse natural habitats, but standard mitigation measures are employed to reduce ecological disturbance.
Frequently asked questions
Oak Grove Graham Substation is located in the United States, near Oak Grove, Florida, at coordinates 30.908598, -87.445859.
Oak Grove Graham Substation operates at 115 kV, which is a medium voltage level commonly used for sub-transmission and distribution in the US electrical grid.
The substation is owned and operated by PowerSouth Energy Cooperative, a generation and transmission cooperative serving Alabama and northwest Florida.
In the United States, substations operating at transmission-level voltages are subject to NERC reliability standards and FERC regulation. For 115 kV facilities, compliance with NERC's Critical Infrastructure Protection (CIP) standards may apply depending on grid criticality.
A 115 kV substation typically steps down voltage from higher transmission levels (e.g., 230 kV or 500 kV) for local distribution or interconnects with other sub-transmission lines. It helps regulate voltage and ensure reliable power delivery to communities.
