GE’s Uninterruptable Power Supply Technology Receives an “eBoostTM” with ecomagination™ Qualification
As energy-demanding datacenters become more prevalent and widely utilized around the globe, finding innovative ways to increase efficiency in existing power supply technologies becomes a necessity. GE Energy’s (NYSE: GE) newly ecomaginationTM-qualified eBoost™ software provides datacenters and IT organizations a way to reduce energy consumption and cost without sacrificing reliability.
The eBoost software has received ecomagination qualification for improving the efficiency of GE’s 225-750 kVA SG Series Uninterrupted Power Supply (UPS) modules. The eBoost software has the ability to increase efficiency from 92-94 percent to 98-99 percent.
The cost and availability of energy for power-hungry computers is a growing concern. National governments and energy industry leaders agree that finding ways to control energy demand while at the same time reducing the nation’s carbon footprint is a must. Data centers are estimated to consume 2 percent of the U.S. electrical grid's capacity resulting in $2 billion per month in utility bills. According to a McKinsey & Company study, estimates of carbon dioxide (CO2) emissions from data centers will quadruple and exceed emissions from the airline industry by 2020 due to the rapid growth in global demand for computing power1.
While most of the industry effort has previously been focused on improving the efficiency of information technology (IT) and cooling equipment, UPS is now in the spotlight for energy optimization with manufacturers such as GE2.
“Energy consumption is a critical issue for IT organizations as their data center energy demands continue to grow,” said Riccardo Rutili—Digital Energy’s general manager for Power Quality. “If the data center industry adopted UPS high-efficiency mode as normal operation, the impact would be significant. For a typical enterprise-class data center with a 5-megawatt load, this can reduce annual energy consumption by more than 3.6 million kWh, or $360,000 at $.10/kWh, assuming 50 percent cooling effectiveness and 50 percent operating load for a typical data center.”
GE’s eBoost provides UPS modules with high efficiency and fast power transfers. It allows a bypass of the power conversion process under normal power system conditions, which in turn saves energy. eBoost software continuously monitors utility power quality and activates double conversion mode only when utility power quality falls outside of data center power quality requirements, reducing the amount of time spent in a less efficient traditional “double conversion” mode. The transfer from the high-efficiency mode to inverter can be completed within 2 milliseconds of eBoost recognizing a system failure to meet power requirements. This “multi-mode” energy efficient operating mode for UPS is included in the Green Grid Data Center Maturity Model as a recommendation for improving data center energy efficiency. The eBoost software also increases reliability and redundancy by enabling up to six UPS modules in parallel operation and by eliminating single points of failure.
The U.S. Department of Energy is focused on green initiatives to improve energy efficiency and has set a target of creating energy savings of 10 percent overall in U.S. data centers, the equivalent of electricity consumed by 1 million typical U.S. households. Based on Frost & Sullivan’s UPS World Reports, replacing the existing installed base of legacy double conversion UPS with those operating in high-efficiency multi-mode would generate at least 4,000 megawatts of energy savings, which would produce annual energy cost savings of more than $3 billion per year.
