Zaininger Engineering Company, Inc.

Resume: Henry W. Zaininger, President

Mr. Zaininger founded Zaininger Engineering Company (ZECO) in 1978. Over the past 31 years he has successfully performed numerous electric utility generation, transmission and distribution system technical and economic assessment studies. He has performed T&D system impact studies with new generation or other T&D facilities installed, including load flow, stability, and post transient voltage and reactive margin assessments as appropriate. He has performed innovative electric power system assessments of a broad range of advanced energy technologies, including solar, wind and biogas renewable resources, energy storage, distributed generation and end use technologies. He has investigated distributed generation interconnection requirements, power quality impacts and potential benefits of distributed resources when integrated into distribution systems. He has investigated requirements to enhance intermittent renewable resource benefits for applications in competitive electric utility system markets. He has determined relative SO₂, NO_x, CO₂ and other emissions for both central stations, distributed generation and end use technology alternatives. He has investigated electromagnetic pulse interaction and coupling with electric power systems. He has provided expert witness services in the both the transmission and distribution system areas. 

Mr. Zaininger was employed by Power Technologies, Inc. for a total of seven years. He was employed by PTI for three years from 1973 to 1976 prior to forming ZECO, returned for two years from 1987 to 1989 to assist in the start up of the Sacramento office, and returned to PTI to serve as manager of the Sacramento office for two years from 1997 to 1999. At PTI, he undertook assignments in both transmission and distribution system planning and line design areas. He evaluated interconnection requirements, assessed transmission reliability and performed power transfer capability studies for interconnecting new generation additions. He served as an expert witness in cases involving large-scale generation connected to a transmission system and small-scale generation connected to a distribution system, developing testimony based on performing T&D system planning studies as appropriate. He developed the initial version of PTI’s transmission line optimization program, LOP1, and performed several EHV line design optimization studies with this methodology. He developed synthetic generation and transmission systems and data for evaluating advanced technologies and new energy resources, and performed several technical and economic assessments of advanced energy technologies and distributed generation, including battery storage and wind generation. 

Mr. Zaininger was employed by the Electric Power Research Institute for one year in 1977.  At EPRI, he participated in technical and economic cost/benefit assessments of a wide range of new energy technologies, and played a significant role in developing the initial version of the EPRI Technical Assessment Guide.  

Mr. Zaininger was employed by Illinois Power Company for five years from 1969 to 1973.  At IP, he served as a system planner, where he performed transmission and distribution system planning studies involving load flow, transient stability, and economic considerations. He was then assigned generation planning responsibilities for the company, where he performed generation planning studies leading to the announcement of two generating units currently on line. These generation planning studies involved reliability assessment, production costing, economic and financial evaluation, future plant siting, and environmental impact assessment of new generation alternatives.  In addition he served as a transmission line design engineer, where he developed complete design specifications for several transmission lines, and developed a new computerized method of structural analysis for both wood and steel transmission structures. 

Mr. Zaininger was employed by Bell Telephone Laboratories for one year in 1968 as a member of the technical staff.  At Bell Labs, he performed computer program development and determined system requirements for computerized telephone electronic switching stations, commonly employed today. 

Mr. Zaininger received his degree in Electrical Engineering from the University of Illinois in 1968 where he was elected into Eta Kappa Nu. He is a senior member of the IEEE. Until recently he served as Chairman of the IEEE‑PES Power System Analysis, Computing and Economics Committee. He is a Registered Professional Engineer in the State of Illinois. He has authored 58 technical publications and has been awarded a patent for the invention of a solar water heating teaching aid.
