| In
this example, a new power plant could
be equipped with a standard turbine
or with a special coating on the turbine
blades which allows to extend the maintenance
intervals. |
| |
| The
"normal“ blades require a
major maintenance during one month every
32,000 operating hours, and the blades
with special coating only every 40,000
hours. |
| |
| This
will result in a benefit of higher production,
but the price for each new set of blades
is higher: 3 mUSD instead or 2.5 mUSD. |

Do
these additional costs for maintenance pay
off?
The criterion to determine whether the two
alternatives have equal benefits should be
the Net Present Value (NPV). |
