Sacramento Municipal Utility District Smart Grid Project

Jump to: navigation, search

Sacramento Municipal Utility District, located in Sacramento, California, will receive $127.5 million in funding to develop a smarter energy grid. The U.S. Department of Energy selected Sacramento Municipal Utility as one of 100 companies to receive federal stimulus funds as part of the American Recovery and Reinvestment Act of 2009.[2]

Sacramento Municipal Utility District’s (SMUD) SmartSacramento Project involves system-wide deployment of an advanced metering system integrated with existing enterprise and information technology systems as well as a partial deployment of advanced distribution grid assets that equip SMUD’s distribution circuits with automated control and operation capabilities. The project also involves customer systems that provide usage and cost information to customers that educate and enable more control over their consumption. These systems enable more informed participation by customers and more effective management by SMUD to improve reliability and efficiency of grid operations and better optimize the use of assets. The project includes a field test of plug-in electric vehicle charging stations to assess their technical performance, vehicle charging patterns, and effects on electric distribution system operations.[3]
