Risk: Medium Substation Operational

JackieHoward Substation - Duke Energy Electrical Substation in the United States

United States

Overview

JackieHoward Substation is an operational electrical substation in the United States, owned and operated by Duke Energy. It handles voltages of 345 kV and 34.5 kV, serving grid stability in the region.

JackieHoward Substation is an operational electrical substation located in the United States, specifically near coordinates 26.564946, -98.698417, likely in Texas. Owned and operated by Duke Energy, a major utility company, the facility plays a critical role in the regional power grid. The substation operates at two voltage levels: 345 kV and 34.5 kV, indicating it serves both transmission and distribution functions. The 345 kV level connects to the high-voltage transmission network, while the 34.5 kV level distributes power to local areas. As part of Duke Energy's infrastructure, it adheres to NERC reliability standards and FERC regulations for grid stability. This facility is essential for maintaining reliable electricity supply in its service area. Its dual-voltage capability allows it to step down power from long-distance transmission lines for local distribution, supporting residential, commercial, and industrial customers. The substation's operational status ensures continued grid resilience in the region.

Environmental context

The substation is located in a rural or semi-rural area of southern Texas, near the Rio Grande Valley. The region experiences a subtropical climate with hot summers and mild winters, which can affect equipment performance and cooling needs. The facility's voltage levels and dual-voltage design indicate it is a critical node for both long-distance transmission and local distribution, potentially impacting land use and requiring vegetation management to maintain clearances.

Frequently asked questions

JackieHoward Substation is located in the United States, with approximate coordinates 26.564946, -98.698417, likely in southern Texas near the Rio Grande Valley.

JackieHoward Substation is an electrical substation that transforms voltage levels between 345 kV (transmission) and 34.5 kV (distribution), helping to deliver electricity from high-voltage lines to local power networks.

JackieHoward Substation is owned and operated by Duke Energy, a major electric power holding company in the United States.

Substations in the US are subject to NERC reliability standards for grid stability and FERC regulations for interstate transmission. Additionally, they must comply with local utility commission rules and safety standards such as IEEE and OSHA.

The 345 kV voltage indicates connection to the high-voltage transmission grid, while the 34.5 kV level serves local distribution. This dual-voltage capability allows the substation to efficiently step down power for regional use, enhancing grid reliability.
