Stages¶

For large projects, like the construction of a new neighborhood, there may be an evolution in energy demands (new buildings, more EVs) and available resources (less reliance on fossil fuels). With stages, you can take these changes into account and plan the optimal energy system and network across decades.
Sympheny may choose to install technologies at the start of a stage and salvage them at the end of the stage, or reuse the technologies in the next stage. The design and operation stay the same within a stage. 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.
