PEC is proposing to build a 138-kilovolt (kV) transmission line to the existing Wimberley Substation, approximately one-half mile north of downtown square in Hays County. The new line will provide more reliable electric service to the homes and businesses in the Wimberley area as well as improve voltage levels.
Hays County is among the nation’s fastest-growing counties, according to U.S. census data. With cities like Wimberley experiencing historic growth, a 138-kV transmission line is needed to meet the increasing demand for electricity and to continue serving our growing membership. PEC has made several improvements to the distribution system in this area, but existing infrastructure will exceed capacity to the Wimberley Substation by 2025. Additionally, load connected to the Wimberley Substation exceeds 20 MW in summer and winter peaks.
