In this step, the Supply Technology Candidates to be considered for installation at the site, including both energy Add Conversion Technology Candidates and Add Storage Technology Candidates, are added to the scenario.  For each technology, various technical, economic and environmental parameters can/must be specified.  A variety of technology specifications can be loaded from Sympheny's built-in technology database, or a custom technology can be specified.

In addition to individual energy conversion and storage technologies, Technology Package Candidates can be added to the analysis, which comprise multiple pre-specified technologies.
