For over a decade, he also served as an expert witness for Pepco Services, Inc., an Exelon company, in numerous base rate case proceedings before U.S. State Public Utility Commissions.

His industry work encompasses: all phases of the base rate design process; market-base rates and formula rates; capital cost recovery mechanisms; other automatic adjustment clauses; electricity and natural gas utility rules and regulations; smart grid (AMI), grid transformation, and distributed energy resources analyses; and cost-benefit analysis and feasibility studies for acquiring energy systems.
