Texas PUC to Submit Proposed Rules for Adoption [Utility, Environmental & Energy Alert]

January 29, 2015

In September 2014, responsibility for regulation of water and wastewater utilities was transferred from the Texas Commission on Environmental Quality (TCEQ) to the Public Utility Commission (PUC). The transfer allows TCEQ to focus on its core environmental mission while taking advantage of PUC’s historic ratemaking expertise. The PUC originally regulated water and sewer rates, and the agency historically has regulated rates and services of electric and telecommunications companies in areas where competition was weak or nonexistent. According to Darryl Tietjen, director of Rate Regulation for the PUC, one of the basic objectives of the move is to make water regulation more consistent with the way electric utilities are regulated.
