Regulating privately built power lines

Who regulates privately built power lines, such as those built by oil and gas companies? It appears that the State of Texas trusts operators to maintain those lines. According to the Texas Tribune, “the state agencies that regulate the energy industry and the power industry said they’re powerless to regulate power lines in the oil patch.” Let’s watch and see if the Legislature addresses this issue or will the Railroad Commission adopt a rule concerning the role of energy operators for electrical problems and notifying the Texas Public Utility Commission if power needs to be cut.
