Abstract
This paper presents the field experiences during the process of bringing the state estimation function on line. Several practical problems involving topology, analog telemetry, equipment parameters, system load calculation, pockets of unobservable buses and external equivalent modeling were identified. Implementation of some trial solutions as a part of Pacific Gas and Electric company´s (PG&E) Energy Management System is presented
