summary & overview

Comparison with PLEXOS by Energy Exemplar

PLEXOS was initially designed for centralized electric energy systems and provides a limited representation of the variability of renewable energy systems. Additionally, PLEXOS needs a local installation, requires external plotting for detailed analysis & debugging, and has no online collaboration features.
