Seattle City Light Contracts for a New Energy Management System

Open Systems International, Inc. has been awarded a contract by Seattle City Light to implement a new Energy Management System (EMS) based on OSI’s monarch platform.

Seattle City Light is the 10th largest public electric utility in the United States. It has some of the lowest cost customer rates of any urban utility, providing reliable, renewable and environmentally responsible power to about 750,000 Seattle area residents. City Light has been greenhouse gas neutral since 2005, the first electric utility in the nation to achieve that distinction.

This new EMS system is based on OSI’s monarch (Multi-platform Open Network ARCHitecture) platform and includes OSI’s next-generation, .NET based Graphical User Interface, large scale SCADA functionality, Generation Management System applications, Transmission Management applications including Advanced Transmission Security Monitoring Analysis functionality, State Estimation, Contingency Analysis and Operator Training Simulator. The new system replaces a legacy Siemens EMS system implemented in the 1990s.

“Seattle City Light is pleased to select OSI to implement our new Energy Management System,” said Phil West, the utility’s energy delivery and customer care officer. “We went through a rigorous selection process and OSI is the best match for our vision of smart grid technology. We look forward to successful implementation of the new EMS, as well as future smart grid projects so we can provide the best service to our customers.”
