Sacramento, Calif.
  • Goal to migrate to a transmission energy management system with enhanced modeling and control capabilities
  • Comprehensive technology solution to improve the transmission network
  • Innovative upgrades include new user interface for enhanced user experience

Siemens successfully deployed its Spectrum PowerTM 7 Energy Management System (SP7 EMS) at community-owned, energy provider Sacramento Municipality Utility District (SMUD). The new SP7 EMS solution is the first installation of Siemen's new platform in North America.

In operation at SMUD for more than six months, SP7 EMS is the centerpiece of Siemens’ large and global investment in energy management technology. The system upgrade is designed to be extensible in functionality - providing additional high-tech components to meet the energy industry’s changing business needs. SP7 EMS has a new user interface, enabling improved user experience to support the most advanced network analysis and operator training solutions available.

With the implementation of SP7 EMS, Siemens also supported SMUD’s participation in the California ISO’s Western Energy Imbalance Market (EIM). The Western EIM is a real-time bulk power trading market, the first of its kind in the western US, allowing participants to buy and sell power close to the time and location where electricity is consumed. Since launching in 2014, the Western EIM has enhanced grid reliability and generated cost savings of $736 million for its participating power companies and consumers.

“SMUD is a community-owned electric utility that aims to deliver safe and reliable power to our customers, said Mark Willis, SMUD Director of Grid Operations. “The new SP7 EMS upgrade provides a means for SMUD to participate in California ISO’s Western Energy Imbalance Market. The Western EIM’s geographic diversity allows easier and more economical balancing and integration of intermittent renewable energy resources, helping SMUD meet its and California’s aggressive renewable and carbon-reduction goals.”

“Siemens is pleased to work closely with SMUD to address the complex grid challenges of today,” says Rafael Ozaki, Business Unit Head for Digital Grid at Siemens Smart Infrastructure USA. “The new SP7 EMS will provide SMUD with versatile tools to help the operating staff to ensure reliable supply, efficient use of generation resources, and reduced transmission losses in both real-time and operation planning phases.”

Siemens offers a wide range of grid solutions across the energy industry. The latest generation of the SP7 EMS includes data acquisition and control, a historical information system, energy accounting, power applications, ICCP, transmission network applications and an operator training simulator.
