OEO develops, maintains, and publishes open-source computer code and data used in energy systems models. OEO uses Tools for Energy Model Optimization and Analysis (Temoa) Python-based optimization model. Temoa takes as input user-specified fuel prices, end-use demands, technology cost and performance characteristics, and policy specifications and projects the least cost expansion and retirement of energy technologies that convert, store, and move energy from extraction to consumption. By modeling the full energy system, Temoa captures key interdependencies among technology and policyOEO develops and maintains a detailed Temoa input database for the United States. Additional resources are available at the model website.
