Please exercise caution and follow our gas safety tips.  Report gas emergencies immediately to 210-353-4357 (HELP).

Martinez Substation


We are planning to construct a new electric substation east of San Antonio in an area roughly bounded by IH 10, Loop 1604, FM 1346 and FM 1516 in Bexar County. We propose to start construction in 2017.

A substation is a local power hub or distribution point for electricity.  This substation will improve reliability and provide additional electric capacity to homes and businesses in the area. The new substation will be supplied from an existing high-voltage transmission line illustrated in the Study Area map shown below.  The substation will supply electric power to homes and businesses in the immediate area through lower-voltage distribution lines.

The substation requires approximately 5 acres; the transmission right of way would be approximately 100 feet wide.

The website will include regular updates on the project as steps are completed. Also, you may call or write to:
