OptGen - Integrated Resource Planning
Optimal long-term planning for generation, transmission, and reserves with a focus on minimum cost and reliability.
Exciting news: OptGen 9.0 is now integrated into SDDP 18
About OptGen
OptGen is a long-term capacity expansion planning model that determines the optimal sizing, least-cost capacity expansion plan, and timing for the construction, reinforcement, and decommissioning of generation capacities, transmission networks, and energy supply chains.

OptGen Optimizes the Balance Between Investment Costs and Operational Costs
OptGen’s goal is to minimize the sum of investment costs for constructing new projects and the expected value of operational costs, subject to reliability constraints in energy supply. OptGen is the only tool on the market capable of co-optimizing Generation, Transmission, and Dynamic Probabilistic Reserves. This way, OptGen can determine which projects should be built and when.

OptGen is Fully Integrated with Our Stochastic System Dispatch Tool
OptGen initiates the optimization process with expansion planning. The subsequent phase, related to operation planning, is conducted by SDDP, our stochastic dispatch model with transmission constraints. This iterative two-phase approach ensures a detailed and balanced representation of supply and demand. By sharing the same database for operational and investment information, OptGen and SDDP continuously refine the expansion plan, ensuring consistency and accuracy across all planning stages.
