Overview
Granite Mountain Substation is an operational electrical substation in Texas, United States, owned and operated by Pedernales Electric Cooperative. It operates at 138 kV, serving the local grid.
Granite Mountain Substation is an operational electrical substation located in Texas, United States. Owned and operated by Pedernales Electric Cooperative, this facility plays a key role in the regional power distribution network. The substation operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. The substation is part of the Pedernales Electric Cooperative system, which serves a large rural and suburban area in central Texas. As a 138 kV facility, it steps down power from higher transmission voltages for local distribution. The equipment likely includes circuit breakers, transformers, and switchgear compliant with NERC reliability standards and FERC regulations. This substation supports grid stability and electricity delivery to homes, businesses, and critical infrastructure in the region. Its location in Texas, a state with a growing population and energy demand, underscores its importance in maintaining reliable power supply. The cooperative ownership model ensures community-focused operation and maintenance.
Environmental context
The substation is situated in a rural area of central Texas, characterized by a mix of grasslands and low-density development. The local environment is subject to hot summers and occasional severe weather, including thunderstorms and winter storms, which can impact grid reliability. The facility's design likely includes measures to withstand such conditions, such as robust grounding and weatherproofing. The surrounding area supports agriculture and wildlife, and the substation's electromagnetic fields are managed within regulatory limits to minimize ecological impact.
