Canada Utility Replacing Energy Management and SCADA System

The New Brunswick System Operator in New Brunswick, Canada, is replacing its Energy Management System (EMS) and Supervisory Control and Acquisition (SCADA) system.

NBSO is a not-for-profit independent corporation whose primary responsibilities are to ensure the reliability of the electrical system and to facilitate the development and operation of a competitive electricity market in New Brunswick. As reliability coordinator for the Maritimes Area, NBSO is the authority responsible for the operation of the Bulk Power System in New Brunswick, Nova Scotia, Prince Edward Island, and a portion of northeastern Maine.

The new system for NBSO will be replacing a legacy system supplied in the 1990s by Telegyr/Siemens. The new EMS is based on Open Systems International's Monarch distributed open architecture. The system will include advanced EMS/Transmission monitoring and optimization applications with functionality such as Network Security Analysis, Topology Processor, State Estimator, Contingency Analysis, Penalty Factor Calculation, Power Flow, Optimal Power Flow, Automatic Generation Control, Economic Dispatch, Reserve Monitoring, Production Costing, Switching Order Management, Operator Training Simulator, and NERC Performance Monitoring.

It also features system interfaces to various corporate systems including Outage Management, Weather System, Market Management, Permit Management, and Corporate Data Warehouse/Historian.
