Springfield, Missouri, City Utilities Using OSI to Replace Energy Management System

Open Systems International, Inc. (OSI) has been awarded a contract by the City Utilities of Springfield, Missouri, to replace its existing Energy Management System (EMS).

City Utilities recently embarked on a competitive bidding process to replace its present Siemens/Telegyr 8000 EMS system. The business drivers that necessitated the change-out included the need for a more open, modern and flexible platform that could adapt easily to business and regulatory changes and allow for easier and more cost-effective annual software upgrades. CU was also looking for a more mainstream product supported by a large user base that could provide new functionality in the areas of IP-based communications, cyber security, disaster recovery, and operator training.

After a rigorous and methodical evaluation of available industry solutions, CU has chosen the OSI technology for its next-generation energy management system.

The proposed project is based on OSI’s monarch distributed open architecture and will include Supervisory Control and Data Acquisition, Automatic Generation Control and Dispatch (AGC), Historical Information Archiving, Calculation and Trending subsystems, Transaction Scheduling and Management, Transmission Network Security Analysis, Operator Training Simulator, interfaces to SPP and ICCP communications.
