PG-ROI shows the result of the additional
investment in the delta analysis, i.
e. the cash-flow obtained by subtracting
the second cash-flow (Open Cycle) from
the first cash-flow (Cooling Tower). |
| |
| On
one hand, there is the additional investment
(blue negative columns) as well as the
credit line and the credit payback correspond
(blue striped columns). |
| |
| The
positive effect on revenues (positive
green columns) and fuel costs (positive
red columns = fuel savings) are very
high, so that the Pay-Off Time is reached
after 1.5 years. |
