The Mid-C Seminar, originally started as an educational class or seminar on trading at the Mid-Columbia hub, it has expanded over the years to cover trading, operational and reliability issues throughout the WECC region, as well as new technology updates. 

Attendees are a mix of traders, marketers, and utility planners from both public and private power and trading firms. It has continued to provide an opportunity to network as well as get an update on important regional issues. While most attendees are from the western region, traders from Houston and other regions, and bankers from New York have also registered over the years.
