Blue Acre Substation - 138 kV Electrical Substation in Texas, United States

Blue Acre Substation is an operational electrical substation located in Texas, United States, under the ownership and operation of Sharyland Utilities. The facility operates at a voltage of 138 kV, classifying it as a medium-voltage substation within the transmission and distribution network. Its location in Texas places it within the Electric Reliability Council of Texas (ERCOT) region, which operates independently from the broader US grid. As a substation operating at 138 kV, Blue Acre Substation plays a role in stepping down transmission-level voltages for local distribution or interconnecting generation sources. The facility is subject to NERC reliability standards and FERC regulations, though ERCOT has its own reliability framework. The substation likely includes switchgear, transformers, and protection systems compliant with ISO/IEC 61850 standards for automation and communication. The substation's operational status and voltage level indicate its importance to local grid stability, particularly in the rural or suburban context of central Texas. Sharyland Utilities, as the owner and operator, is responsible for maintaining the infrastructure to ensure reliable power delivery to surrounding communities. The facility contributes to the resilience of the regional electrical infrastructure.

The substation is located in a region with a semi-arid climate, where extreme weather events such as thunderstorms and occasional winter storms can impact grid reliability. The 138 kV voltage level suggests the substation serves a mix of residential and commercial loads, with potential for integration of renewable energy sources common in Texas, such as wind and solar. The facility's design likely includes measures to mitigate environmental impacts, such as oil containment for transformers and noise reduction.
