Siemens Energy Inc. has been selected by Hawaiian Electric Company to provide a smart grid solution to integrate automation of the distribution grid and thus improve reliability and operational efficiency as part of the utility's $5.3 million share of federal smart grid stimulus funds. The "East Oahu Transmission Project – Phase 2" will automate high-load distribution circuits feeding sections of eastern Oahu. It offers an innovative system design and operations approach, minimizing construction impacts to the community and reducing potential outage times from hours to minutes.
The scope of the project includes establishing an intelligent 46-kilovolt substation feeder infrastructure integrated with the existing control center solutions, including feeder automation, installing intelligent substation controllers, automated switches and reclosers to quickly isolate and restore power (self-healing grids); advanced control center grid visualization, intelligent information analysis/filtering and tools for "predictive analysis" of operations problems; extension of cost-effective standard/open communication for the 46 kV sub-transmission system; and development of a standard repeatable installation process. Hawaiian Electric already uses Siemens Spectrum Power TG energy management system.
"With Siemens' help, Hawaiian Electric has developed a smart grid automation methodology that will be applied to eight substations in a critical urban load center in Honolulu," said Harold Kageura, vice president of energy delivery at Hawaiian Electric. "The grant will help fund a $15.4 million project to help us continue to enhance our grid and provide reliable power to Oahu residents."
"The approach is focused on reliability improvement while maximizing asset life, increasing asset utilization and overall value," said David Pacyna, senior vice president and general manager of Siemens Energy Inc.'s Transmission and Distribution Divisions. "It moves Hawaiian Electric's distribution grid design from an 'adding more capacity for reliability' paradigm to one of 'leveraging existing capacity through monitoring, control and automation for improved reliability.'"
Siemens' approach also significantly reduces environmental permitting and construction processes, thereby minimizing disruption to the local community. It establishes the solution base to effectively integrate Hawaiian Electric's operations and maintenance organizations and processes by adding predictive, condition and event-driven maintenance programs.
Because Siemens understands the complete energy conversion chain, we're able to transform today's grid into a living infrastructure that is smart enough to respond quickly, flexibly and comprehensively to society's energy needs. And Siemens also incorporates solutions for commercial and industrial applications as well as smart homes including building automation, IT systems integration, advanced lighting technology and energy efficient appliances for a comprehensive smart grid solution.
