Invensys Implementing InFusion-based Generation Management System for Williams Power.

FOXBORO, Mass. -- Williams Power has selected Invensys to implement an InFusion-based Generation Management System (GMS) for its fleet of electrical generation assets. These assets include two company-owned power plants and six contracted facilities located across seven states.

The new system will integrate data from many different automation systems and applications to help Williams precisely schedule the delivery of generation capacity from each plant according to changing demand from contracted markets.

The GMS will monitor demand trend data by communicating with the three contracted ISO (Independent System Transmission Operator) organizations that serve California (CAISO), the Midwest (MISO) and Mid-Atlantic states (PJM). In the competitive deregulated generation market, the ISOs are responsible for monitoring and directing the flow of wholesale electric power into and throughout the distribution grids that serve their regional markets.

Having all plant data and market demand data in a centralized business decision support environment will allow Williams to provide set point dispatch control for production from the generating plants on an hourly basis. This real time scheduling will help prevent shortfalls in capacity, as well as the generation of too much electricity, minimizing economic risk in the business and optimizing the production value of each Williams generation asset.

The new Infusion-based system, which replaces an existing SCADA system, will provide Williams Power with a more flexible, easier-to-deploy, standards-based data acquisition and business decision support platform that will be able to adapt to future changes in asset configuration and energy market characteristics.
