Consumer protection was another hallmark of Wellinghoff's career prior to joining FERC. In his hometown of Reno, he held the position of Deputy District Attorney in the Washoe County District Attorney's Consumer Fraud division. His work on behalf of consumers helped make him Nevada's first Consumer Advocate for customers of public utilities. In that role, he argued for the public in cases before FERC, the Nevada Supreme Court and what is now the Nevada Public Utility Commission.
