New England Utility Contracts with OSI for T&D Control System

Open Systems International, Inc. has been awarded a contract by a New England electric company for the supply of a comprehensive Supervisory Control and Data Acquisition system for monitoring and controlling of its transmission and distribution networks. For confidentiality reasons, the name of the utility is withheld.

The utility's main objective for this project has been the implementation of a modern, open and secure architecture, facilitating the utility's growth requirements and compliance with NERC mandated security and reliability standards.

The utility company serves energy to approximately 40,000 retail customers in a 4000-square mile area in rural northern New England via a transmission and distribution network that spans nearly 2500 circuit miles.

The proposed system is based on OSI's Monarch distributed open architecture and includes Supervisory Control and Data Acquisition, Historical Information System, Secure ICCP communications, Calculation Subsystem, Trending and a backup control center. Optionally, in a later phase, Energy Management System applications including Transmission Security Analysis and Operator Training Simulator will be added to the present system.
