Overview
Dorrell Substation is an operational electrical substation in Texas, United States, operated by Sam Houston Electric Cooperative. It operates at 138 kV, serving the local grid.
Dorrell Substation is an operational electrical substation located in Texas, United States. It is owned and operated by Sam Houston Electric Cooperative, a member-owned utility serving rural and suburban areas. The substation operates at a voltage of 138 kV, classifying it as a high-voltage transmission-level facility within the regional power grid. As a 138 kV substation, Dorrell Substation plays a role in stepping down transmission voltage for distribution to local communities. In the United States, such facilities are subject to NERC reliability standards and FERC regulation for grid stability. The substation's equipment likely includes circuit breakers, transformers, and switchgear compliant with IEEE standards, typical for this voltage class. The substation supports the electrical infrastructure of southeastern Texas, an area prone to severe weather events like hurricanes. Its role in maintaining grid reliability is critical for local residential and commercial customers. The cooperative ownership model emphasizes community service and resilience planning.
Environmental context
Located in a rural area of Texas, Dorrell Substation operates in a region with hot summers and occasional severe storms. The substation's design likely includes measures for flood resilience and vegetation management to prevent outages. Its 138 kV voltage level places it in a medium-scale category for transmission infrastructure, balancing local distribution needs with regional grid connectivity.
