A discussion of data center power challenges across the system

Data centers are fast-growing electricity consumers. Electric power system configurations and energy management opportunities are discussed across all levels of a data center, with emphasis on building distribution and dc conversion. Several strategies that enhance center energy efficiency are discussed. The general issues are related to energy and reliability needs of telecommunications power systems. It is shown that best-case scenarios based on emerging methods can achieve energy reductions approaching 30% for data centers.
