OptGen

OptGen is a long-term capacity expansion planning model that determines dimensioning, least-cost capacity expansion planning and optimal timing for construction, reinforcement and retirement of generation capacities, transmission networks and energy supply chains.

Modeling Capabilities

Full integration with SDDP

Leverage the full capabilities of our stochastic dispatch model

Environmental criteria

Incorporates clean energy certificates, emission costs and caps to meet sustainability goals

Resilience planning

Accounts for high-impact, low-probability events to enhance system robustness

Investment cost reduction curves

Reflects technological advances and other factors to capture evolving investment costs

Project relationship constraints

Manages mutually exclusive projects, associative constraints, and precedence between investments

Reliability

Allows energy supply reliability criteria using Coral, our reliability tool

Firm energy and firm capacity constraints

Enforces system policies to ensure secure supply

Governmental energy policies

Adheres to decarbonization policies and renewable energy penetration targets

Flexibility

Integrates Dynamic Probabilistic Reserve (DPR) in the expansion planning process

And much more...

OptGen optimizes the trade-off between investment costs and operating costs

The objective of OptGen is to minimize the sum of investment costs to build new projects and expected value of operating costs, subject to supply reliability constraints. OptGen is the only tool in the market capable of co-optimizing Generation, Transmission and Dynamic Probabilistic Reserves. That way, OptGen is capable of determining which projects should be constructed and when.

SDDP and OptGen are recognized as a best-in-class energy market simulation engines, providing leading analytical tools and support for professionals such as modelers, power producers, and analysts.

OptGen is fully integrated with our stochastic dispatch tool of the system

OptGen initiates the optimization process with expansion planning. The subsequent phase, relative to operation planning, is driven by SDDP, our transmission-constrained stochastic dispatch model. This iterative dual-phase approach ensures a detailed and balanced representation of supply and demand. By sharing the same database for operational and investment data, OptGen and SDDP continuously refine the expansion plan ensuring consistency and accuracy across all planning stages.
