Blossom Substation


We plan to construct a new electric substation in the near north east area of San Antonio on Starcrest Dr. The new substation will be supplied from an existing high-voltage transmission line that runs next to Starcrest Dr. The substation will supply electric power to homes and businesses in the immediate area, largely using existing lower-voltage distribution lines. The site selected for this infrastructure is owned by us.

A substation is a local power hub or distribution point for electricity. This substation will provide additional electric capacity to support community growth and it will improve the reliability of electric services to homes and businesses in the area.

Construction of the substation is tentatively scheduled to begin in March 2016 and be completed in June 2017. We would like to thank you in advance for your patience and understanding as we work to continue delivering dependable, affordable energy to you and your neighbors.

This page will include regular updates on the project as steps are completed.
