OSI Provides Energy and Distribution Management Systems in Las Vegas and Reno

Open Systems International, Inc. has been awarded a comprehensive new contract by NV Energy Inc. to supply next-generation SCADA and Energy Management platforms for its two Nevada subsidiaries, Sierra Pacific Power Co. in Reno; and Nevada Power Co. (NPC) in Las Vegas.

NVE is an investor-owned energy utility based in Las Vegas, Nevada that provides energy services to a 54,500-square-mile territory in the state of Nevada, including more than 2.4 million residents as well as an annual state tourist population that exceeds 40 million people.

In anticipation of the pending 'One Nevada Transmission Line' (ON Line) project; a 230-mile, 500 kV north-south AC transmission line set to interconnect the transmission systems of NV Energy's subsidiaries in northern and southern Nevada, NVE has embarked on a system modernization project, choosing OSI to upgrade and enhance its energy management and control infrastructure, replacing and consolidating two existing legacy energy management systems.

These new systems are based on OSI's Monarch distributed open architecture; featuring an advanced Microsoft .NET based Graphical User Interface and including Supervisory Control and Data Acquisition (SCADA), Automatic Generation Control and Dispatch (AGC), Historical Information Systems (HIS), Transmission Network Analysis, Web-based Graphical User Interfaces, Operator Training Simulator, Secure ICCP communications, as well as functionality for hot standby backup/disaster recovery control systems. With these new and networked systems, NVE is planning to retain Transmission and Distribution operation for both utilities in their respective locations, Las Vegas and Reno, while providing balancing authority EMS functions for the consolidated transmission network in its Reno location.
