Stages¶

Technologies go through stages for installation, use, and potential reuse. Each stage has its own associated costs and demands. You define which stages each technology can be in. Technologies can be installed at the start of a stage and reused or salvaged at its end. The design and operation stay the same within a stage, which lets you optimize long-term projects with multiple phases of investment. For parameters, see Stages parameters.
Note
Sympheny uses discounted cash flow (DCF) analysis to convert the total cost (represented by the net present cost, NPC) into an annual cost. See Discounted cash flow analysis for details.
