Ren Orans

Dr. Ren Orans, Managing Partner + Dr. Orans founded E3 in 1989 and leads the firm’s litigation support and utility planning functions. With more than 25 years of experience in the energy industry, Dr. Orans’ work in utility planning is centered on the design and use of area- and time-specific (ATS) marginal costs for both pricing and evaluation of grid infrastructure alternatives. Using costs Dr. Orans developed, PG&E became the first electric utility in North America to use ATS costing in its ratemaking. This seminal work led to detailed area costing applications in pricing, marketing and planning for many utilities. He is an expert in designing wholesale transmission tariffs and has served as an expert witness on transmission rates for Canada’s three largest utilities (BC Hydro, TransEnergie and Ontario Power Generation). He frequently provides expert advice to large utilities on retail rate design and wholesale transmission pricing.
