that can amount to more than twice the purchase price of
the EVR in just 10 years.

It is important to note that there are soft costs that further
strengthen the argument for consideration of an EVR that
are not included in these calculations. These soft costs
include:

Reimbursements to dissatisfied guests for stays or
conference events impacted by power-quality issues

Adverse impacts on carefully cultivated marketing assets,
such as customer loyalty, ranking, and reputation

Reductions in sales volumes generated from attractions
including, but not limited to casino gaming, directly or
indirectly related to power outages, brownouts, and other
power-related disturbances

These soft or “hidden” costs can significantly add to a
property’s bottom line and positively impact an EVR’s actual
return on investment. Adding an EVR improves power
continuity and reduces total ownership costs. Because
the generator and UPS can be reserved for providing
supplementary power during true power outages and not
for under-voltage situations, the total system operates more
effectively, minimizes preventable downtime, prevents
premature equipment failure and data corruption, and
preserves all-important guest-service scores.
