Overview
Eagle Creek Substation is an operational electrical substation owned by CPS Energy in the United States, operating at 138 kV to support grid stability.
Eagle Creek Substation is an operational electrical substation located in the United States, owned and operated by CPS Energy. The facility operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level infrastructure, serving as a critical node in the regional power grid. As a substation operating under the jurisdiction of the United States, it adheres to NERC reliability standards and FERC regulations for transmission-level assets. The 138 kV voltage class is commonly used for bulk power delivery to large industrial customers and distribution networks, requiring robust switchgear and protection systems compliant with ISO/IEC 61850 automation standards. The substation plays a key role in maintaining grid stability and reliability for the surrounding area. Its location in Texas, a state with a growing population and industrial base, underscores its importance in supporting energy demand and integrating diverse generation sources into the grid.
Environmental context
The substation is situated in a region characterized by a mix of urban and rural landscapes, typical of south-central Texas. The local environment includes semi-arid conditions with occasional extreme weather events such as heatwaves and thunderstorms, which can impact grid operations. The facility's design likely incorporates measures to mitigate environmental risks, such as fire-resistant construction and stormwater management, to ensure continuous service.
Frequently asked questions
Eagle Creek Substation is located in the United States, specifically in the state of Texas, with coordinates approximately 29.2248° N, 98.2539° W.
Eagle Creek Substation operates at a voltage of 138 kV, which is a common sub-transmission voltage level used for distributing power from transmission lines to local distribution networks.
Eagle Creek Substation is owned and operated by CPS Energy, a municipal electric utility serving the San Antonio area in Texas.
Substations in the United States must comply with NERC reliability standards for grid stability and FERC regulations for transmission assets. Additionally, automation and communication systems often follow the ISO/IEC 61850 standard.
A 138 kV substation serves as an intermediate step between high-voltage transmission lines (typically 230 kV and above) and lower-voltage distribution networks (e.g., 34.5 kV or 12 kV). It steps down voltage and routes power to industrial, commercial, and residential customers.
