The ASSET Lab Resource adequacy package (assetra) is a light-weight, open-source energy system resource adequacy package maintained by the University of Michigan ASSET Lab.

• Free software: MIT license
• Documentation: https://assetra.readthedocs.io.

• Probabilistic Monte Carlo state-sampling simulation framework, supporting:

  • Time-varying forced outage rates in thermal units
  • Sequential storage unit dispatch
  • User-defined energy unit types

• Resource adequacy calculation:

  • Expected unserved energy (EUE)
  • Loss of load hours (LOLH)
  • Loss of load days (LOLD)
  • Loss of load frequency (LOLF)

• Resource contribution calculation:

  • Effective load-carrying capability (ELCC)

• Object-oriented interface to manage energy units within energy systems
• Internal computation stored in xarray datasets

This package was created with Cookiecutter and the audreyr/cookiecutter-pypackage project template.
