Subestación Rafter


We are planning to construct a new electric substation near the Medina and Bexar County boundary line. The new substation will be supplied from an existing high-voltage 138kV transmission line that runs near Potranco Rd.  The substation, which will be constructed on private property, will supply electric power to a large customer located on Lambda Drive.

A substation is a local power hub or distribution point for electricity. This facility will require approximately 7 acres and the transmission right of way will be approximately 150 feet wide.

Construction of the substation is tentatively scheduled to begin in May 2016 and be completed in June 2018. We would like to thank you in advance for your patience and understanding as we work to continue delivering dependable, affordable energy to our customers.
