Base Case Assumptions

From the previous result, there might arise another question:
How much lower could the output (MW) be so that the additional investment for the open cooling water cycle still reaches a three year Pay-Off Time?
 
Spemann PG-ROI quickly finds the solution with the goal-seek analysis: 717.89 MW.

Even if the output dropped with the open cycle compared to the cooling tower, the additional investment still would pay off within three years, due to the savings of fuel costs from higher efficiency.
