Minneapolis, MN, June 5, 2008 -- Open Systems International Inc. (OSI) has been awarded a joint-contract by Chugach Electric Association Inc. (Chugach) and Anchorage Municipal Light & Power (ML&P) to be the supplier of each utility's energy management system (EMS) technology.
Each utility's primary objective for the project has been the implementation of a more modern and open EMS which provides for regular software updates and remains current with evolving cyber security standards, while providing cost efficiencies in managing their transmission, generation and distribution operations. The new OSI systems replace current SPECTRUM EMS systems supplied by Siemens.
The proposed systems are based on OSI's monarch distributed open architecture with an advanced graphical user interface based on Microsoft's .NET technology, and include supervisory control and data acquisition (SCADA), automatic generation control and dispatch (AGC), switch order management, inadvertent accounting, transaction management scheduling, equipment outage scheduling, real-time and study network analysis, historical information/recording system, Web-based graphical user interface, calculation and trending subsystem and DNP, modbus and ICCP communications.
Chugach generates, transmits and distributes electric power to approximately 80,300 metered retail locations in a service territory which extends throughout Anchorage, AK, and its surrounding regions. Chugach operates approximately 2,206 miles of energized transmission and distribution lines, and has approximately 530 MW of installed capacity.
ML&P also generates, transmits and distributes electric power, servicing over 30,000 residential and commercial customers within the Municipality of Anchorage. The company's transmission and distribution lines cover approximately 400 miles, with a total generating capacity of approximately 400 MW.
