Stages

Technologies go through stages for installation, use, and potential reuse. Each stage has its associated costs and demands. You'll define which stages each technology can be in. Technologies can be installed at the start and reused or salvaged at the end of a stage. The design and operation stay the same within a stage. This allows optimization of long-term projects with multiple phases of investments. For parameters, see the Stages Parameters section.
