9. 9. 96.5% A TCO evaluation of the OpEx costs of operating a UPS over 10 years creates an operational savings of \$1.4 million when energy efficiency improves a single percent — from 93 to 94 percent efficiency. With newer UPS technologies that offer up to 96.5 percent efficiency, that savings jumps to almost \$3.4 million. Therefore, a one percent gain in energy efficiency matters.

CapEx 93% Total cost of ownership (TCO), the sum of capital expenditures lCapEx) and operational expenditures (OpEx), is a critical metric to understanding true and long-term costs when designing a new facility or selecting equipment. Yet with the explosion of data center expansion, identifying TCO variables when specifying, building and operating a data center may be more elusive, costing companies millions of dollars every year.
