OptimalSolution LLC

Welcome to OptimalSolution LLC — a consulting and software practice supporting decarbonization strategies, cross-platform energy modeling, and open-source development for energy system transitions.

We work with researchers, governments, and model developers to:

  • Develop and maintain long-term energy system planning models
  • Provide training and technical assistance to teams working on energy transition projects
  • Evaluate disruptive technologies and low-carbon pathways
  • Translate models across GAMS, Pyomo, JuMP, and GMPL
  • Build and deploy open-source tools and modeling interfaces
  • Support cloud-based and reproducible modeling workflows

See Services & Offerings for more details on how we can help.

Studies and Tools

We develop in collaboration, maintain, and apply several open-source tools and frameworks for energy system modeling and analysis. These tools are designed to be transparent, extensible, and reusable across different platforms and applications.
Open source projects include (but not limited to):

  • USENSYS United States Energy System Optimization Model
  • IDEEA Indian Zero Carbon Energy Pathways
  • CEPRO China Electric Power Sector Optimization Model
  • energyRt — Macro-energy system modeling in R
    Scenario-driven, modular, open framework
  • multimod — A domain-specific language for mathematical models Bridges GAMS, JuMP, Pyomo, LaTeX
  • see more in Projects
