Stillwater 69 Substation - Stillwater, Oklahoma | United States Electrical Infrastructure

Stillwater 69 is a substation located in Stillwater, Oklahoma, United States, operated by the Grand River Dam Authority (GRDA). The facility operates at a voltage of 69 kV, which is typical for sub-transmission and distribution-level infrastructure, serving as a critical node in the local electrical network. As a substation, Stillwater 69 is part of the broader electrical infrastructure that ensures reliable power delivery. In the United States, substations like this are subject to NERC reliability standards and FERC regulations, which mandate operational protocols for grid stability. The 69 kV voltage level places it in the medium-voltage category, often used to distribute power from transmission systems to local distribution networks. The facility's operational status is active, contributing to the resilience of the regional grid. Its location in Stillwater supports the energy needs of the surrounding community and industrial users. The Grand River Dam Authority, a public power utility, oversees its operation, aligning with Oklahoma's energy landscape that includes hydroelectric and natural gas generation.

The substation is situated in a region characterized by a mix of urban and rural areas, with the local climate featuring hot summers and cold winters. Electrical infrastructure like Stillwater 69 is designed to withstand such conditions, with equipment rated for temperature extremes. The facility's voltage level and location influence its environmental footprint, primarily through electromagnetic fields and land use, though modern substations are engineered to minimize ecological impact.
