Overview
Screwbean Substation is an operational electrical substation in Texas, United States, owned and operated by Oncor. It handles voltages of 138 kV and 22 kV, supporting regional grid stability.
Screwbean Substation is an operational electrical substation located in Texas, United States. Owned and operated by Oncor, a major transmission and distribution utility, the facility plays a key role in the regional power grid. The substation handles voltages of 138 kV and 22 kV, indicating its function in stepping down transmission-level power for local distribution. Operating under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), the substation adheres to mandatory reliability standards. Oncor's infrastructure is subject to Texas's competitive electricity market, with oversight from the Public Utility Commission of Texas (PUCT). The 138 kV voltage level is typical for sub-transmission networks, while 22 kV serves local distribution. The substation is situated in a rural area of West Texas, characterized by arid climate and sparse population. Its location supports the electrical needs of nearby communities and industrial activities, including oil and gas operations. As part of Oncor's extensive network, Screwbean Substation contributes to grid resilience and power delivery in the region.
Environmental context
The substation is located in a rural, arid region of West Texas with low population density. The surrounding landscape is dominated by desert scrub and agricultural land. Electrical infrastructure in such areas must withstand extreme temperatures and occasional dust storms. The facility's voltage levels (138 kV and 22 kV) indicate a role in both transmission and distribution, with potential environmental considerations related to electromagnetic fields and land use for transmission corridors.
