About.

Combined, our Engineers have more than 120 years experience in electric power transmission. Some of our staff's accomplishments have been acknowledged in the industry by their being elected Fellows of the IEEE. Our younger employees continue this tradition, chairing committees, subcommittees and working groups within the IEEE. Every member of our staff is a respected industry expert in his/her specialty.

​PDC's stature in the industry is reflected in the number of associate consultants who have maintained long-term alliances with Power Delivery Consultants, Inc. These associates have distinguished careers at utilities, manufacturers, and consulting firms, and have chosen to join PDC's team to provide their expertise to the unique and challenging projects that are PDC's specialty.

Mr. Williams joined the Consolidated Edison Company of New York in 1965, and held engineering positions in several groups at Con Edison until he joined Power Technologies, Inc. in 1973. He served in the U.S. Air Force, Base Civil Engineers, in the 1960’s. He and John Cooper founded Power Delivery Consultants, Inc. in 1992.
Mr. Williams has conducted technical and economic studies of alternate underground systems, for voltages from 138 kV to 765 kV ac, as well as HVDC. He has prepared testimony and represented utilities and commissions in hearings. He designed and supervised the construction of an extensive uprating project for existing pipe-type cables, and has been responsible for engineering analysis, specifications, bid review, and field supervision for many underground and submarine cable projects for both utilities and architect-engineers.
In addition to utility design/installation projects, he was project engineer for the EPRI –funded development of the ACE program to perform technical and economic analyses of cable systems. He was technical editor and principal author of the 1992 edition of the Underground Transmission Systems Reference Book and authored sections of the 2006 edition. He was also project engineer for the EPRI Underground Transmission Workstation project, as well as several other EPRI-funded projects including the Distributed Fiber Optic Temperature Monitoring development.
Mr. Williams is a Life Fellow of the IEEE, and member of the Power Engineering Society and Electrical Insulation Society. He is a Voting Member of the IEEE Insulated Conductors Committee and was Chairman of the Insulations Subcommittee. Mr. Williams has authored more than fifty technical articles and papers, and was co-author of the Underground Transmission Systems section of the McGraw-Hill Standard Handbook for Electrical Engineers.

Mr. Williams is a registered Professional Engineer in the States of New York and Ohio.
