This paper covers the operating experiences with the automatic and supervisory control from a System Control Center of the Calgary Power Ltd. hydroelectric system; some design features are given in a companion paper.' The purpose of the paper is to prove the feasibility of a complete hydroelectric system consisting of unattended automatic plants and substations under the control of a System Control Center as regards service, property, and economics. It is hoped its context will be of value to engineers and utility executives contemplating similar projects.
