Reagan Street Substation - Dallas, Texas Electrical Substation

Reagan Street Substation is an operational electrical substation located in Dallas, Texas, United States. Owned and operated by Oncor, a major transmission and distribution utility in Texas, this facility plays a key role in the regional power grid. The substation handles primary voltage of 138 kV and secondary voltage of 12.5 kV, indicating its function as a step-down substation serving urban and industrial loads. Operating under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Electric Reliability Council of Texas (ERCOT), the substation adheres to mandatory reliability standards. Oncor, as the owner and operator, is subject to oversight by the Public Utility Commission of Texas (PUCT). The facility's voltage levels and urban location in Dallas highlight its criticality for grid stability and local power distribution. The substation's environmental context involves its urban setting in Dallas, where it supports dense residential, commercial, and industrial electricity demand. Its role in the ERCOT grid, which is largely isolated from other US interconnections, underscores its importance for local energy security. Typical urban substations in Texas are modernized to meet growing demand and reliability requirements.

Located in an urban area of Dallas, Texas, Reagan Street Substation operates within a high-demand environment typical of major US cities. The substation's voltage levels (138 kV and 12.5 kV) indicate its role in distributing power from transmission lines to local distribution networks. Urban substations like this are critical for grid stability, especially in ERCOT, which faces unique challenges due to its isolation from other US grids. The facility's environmental impact is primarily related to land use and potential electromagnetic fields, but modern design standards mitigate these concerns.
