Overview
Dollarhide Substation is an operational electrical substation in Texas, United States, owned by Oncor. It operates at 138 kV and 25 kV, serving as a key node in the regional power grid.
Dollarhide Substation is an operational electrical substation located in Texas, United States. Owned and operated by Oncor, a major transmission and distribution utility, this facility plays a critical role in the regional power grid. The substation handles voltage levels of 138 kV and 25 kV, indicating its function in both high-voltage transmission and local distribution. As part of the U.S. electrical infrastructure, Dollarhide Substation operates under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) for wholesale electricity markets and the North American Electric Reliability Corporation (NERC) for reliability standards. Oncor, as a transmission owner, must comply with NERC's Critical Infrastructure Protection (CIP) standards and Texas's regional grid requirements managed by the Electric Reliability Council of Texas (ERCOT). The substation likely features modern switchgear and automation systems to ensure grid stability. The substation's location in Texas places it within a region with high electricity demand due to industrial activity and population growth. Its role in stepping down voltage from transmission to distribution levels supports local communities and businesses. The facility's operational status ensures continued reliability for the surrounding area, contributing to the overall resilience of the ERCOT grid.
Environmental context
The substation is situated in a semi-arid region of Texas, where extreme weather events like heatwaves and droughts can stress the power grid. Its design likely includes measures to withstand high temperatures and occasional severe storms. The facility's voltage levels and urban proximity influence its environmental footprint, with considerations for electromagnetic fields and land use.
