Hydro-Quebec's long-term model for changing over to digital substation control and monitoring systems specifies three phases, each marked by a technology stage. Hydro-Quebec is today at phase 2, with over 60 operational installations. Technology stage 2 has just been redefined to cover the integration of intelligent peripheral devices in the ALCID system. Phase 2 and 3 of the long-term model are now being adjusted, on the basis of experience feedback from the last seven years, to offer a closer match to market conditions, manufacturers offers, and operating requirements in the present-day context of deregulation and unrestricted network access. Through this pragmatic stage-by-stage approach, Hydro-Quebec enjoys prompt access to digital technologies at a reasonable cost, while allowing itself sufficient time to make the necessary organizational adjustments in plant engineering, operation and maintenance.
