Overview
Amber Jack Substation is an operational electrical substation in Texas, United States, operated by Oncor. It operates at 138 kV, serving as a key node in the regional transmission grid.
Amber Jack Substation is an operational electrical substation located in Texas, United States. Owned and operated by Oncor, a major transmission and distribution utility in the state, the facility plays a role in the regional power grid. The substation operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. As part of the U.S. electrical infrastructure, Amber Jack Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). Oncor, as a transmission owner, must comply with NERC reliability standards to ensure grid stability. The 138 kV voltage level is common for connecting distribution networks to higher-voltage transmission lines, supporting local load centers. The substation's location in Texas places it within the Electric Reliability Council of Texas (ERCOT) interconnection, which manages the state's power grid. Substations like Amber Jack are critical for voltage regulation and power distribution, contributing to the reliability of electricity supply for residential, commercial, and industrial customers in the region.
Environmental context
The substation is situated in a rural area of western Texas, characterized by arid climate and low population density. Electrical infrastructure in such regions often supports oil and gas operations, agriculture, and renewable energy projects like wind and solar farms. The 138 kV voltage level indicates a role in distributing power from transmission lines to local distribution networks, with minimal direct environmental footprint beyond land use and electromagnetic fields.
