Alliant Energy of Madison, Wisconsin, U.S., has ordered an advanced, centralized Volt/VAR Control (VVC) system from Open Systems International (OSI).

Based on OSI's monarch (Multi-platform Open Network ARCHitecture) and OSI Spectra distribution management system platforms, this multi-phased VVC system project will enable Alliant Energy to reduce system losses, manage reactive power supply and provide the future ability to implement conservation voltage reduction. The project will initially span 333 distribution feeders.

This system will feature the advanced functionality of OSI's next-generation graphical user interface, geographic information systems interface, distribution power flow, and conservation voltage-reduction products, with a monarch interface to Alliant Energy's AMI system.
