Harry L. Terhune, Assistant Executive Director of the Mid-America Interconnected Network (MAIN) will discuss last summer's critical electric power supply operating conditions, including the events underlying the infamous "price spikes" of June 25, 1998.
Mr. Terhune will report on the analysis and projection of reliability conditions performed by regional and national reliability groups during the spring, reflecting the impact of extended nuclear outages. He will also describe the actions taken by MAIN and its member electric utilities to prepare for potentially constrained capacity and transmission conditions. Finally, he will cover the actual performance of the MAIN systems in Wisconsin, Illinois and Missouri during the summer of 1998, including transmission loading relief events and emergency capacity relief actions.
Harry L. Terhune graduated from the University of Notre Dame with the BSEE degree in 1967, and received the MSEE degree from the Illinois Institute of Technology in 1975, after doing thesis work in wide-area blackouts.
