Our Story

The Oak Tree Group consultants is a group of former Pennsylvania Public Utility Commission (PA PUC) Safety and Rates Engineers and Utility Financial Analysts, that was formed to assist small natural gas distribution system companies, master meter operators, and Act 127 Operators with federal & state pipeline safety compliance, as well as utility rate case and tariff support, and natural gas (NGS) and electricity supplier (EGS) broker/marketer license applications. We are comprised of a small group of federally certified pipeline safety inspectors and utility financial & rate analysts.

The Oak Tree Group is the only utility consulting company in Pennsylvania with both federally trained and Commonwealth trained safety engineers, in addition to having experience in PA PUC utility rate design, cost of service, rate base, revenue and expenses, and NGS/EGS license applications. As former PA PUC employees who have over 75 years of combined regulatory experience, we are uniquely qualified to support your company through the maze of government regulations, and to ensure that you are in compliance with federal and state pipeline safety regulations, and all PA PUC filing requirements.  

​If your company is experiencing compliance issues with 49 CFR 191, 192, 193 &195 or need assistance with other PA PUC issues related to small natural gas utility companies, and NGS/EGS licensing, please contact us. The Oak Tree Group can lead you into compliance and formulate procedures to ensure future compliance.
