The RGGI Carbon Market Scenario Simulator is designed to model demand and supply dynamics within the Regional Greenhouse Gas Initiative market. The tool provides structured scenario analysis to help market participants evaluate allowance balances, price formation, and long term compliance outcomes under varying emissions and policy assumptions. This updated version incorporates key structural revisions adopted under RGGI’s Third Program Review, along with cCarbon’s latest emissions forecasts. As RGGI transitions into a tighter cap trajectory with revised cost containment mechanisms, understanding the interaction between supply adjustments and evolving decarbonization pathways has become increasingly important.

Core Capabilities

The simulator enables users to model a wide range of emissions trajectories reflecting different levels of regional decarbonization. Users can assess outcomes under assumptions such as:

• Slower renewable buildout and higher fossil generation persistence
• Accelerated clean energy deployment
• Variations in electricity demand growth
• Changes in fuel switching behavior
• Structural impacts from federal or state policy shifts

By selecting different emissions pathways, users can evaluate how annual and cumulative allowance balances evolve over time and how those balances may translate into price pressure.

Incorporation of Third Program Review Revisions

This version integrates major programmatic updates resulting from RGGI’s Third Program Review, including:

• A revised and tightened cap trajectory
• Adjustments to reserve mechanisms
• Updated cost containment features
• Structural modifications affecting supply responsiveness

These changes materially influence long term market fundamentals. The simulator reflects updated allowance budgets and reserve dynamics to ensure consistency with the latest regulatory framework.

Updated Emissions Forecast

In addition to program revisions, the model incorporates cCarbon’s updated emissions forecast for the RGGI region. This forecast reflects recent trends in power sector generation, fuel mix shifts, renewable deployment, and policy driven decarbonization impacts. By combining revised program design with updated emissions expectations, the simulator provides a coherent analytical framework for assessing potential surplus or deficit conditions across compliance periods.

Analytical Applications

The RGGI Scenario Simulator is designed to support strategic decision making for compliance entities, traders, investors, and policymakers. Key applications include:

• Evaluating price risk under alternative decarbonization pathways
• Assessing the likelihood and timing of reserve trigger events
• Measuring cumulative surplus or deficit balances
• Testing sensitivity to economic growth and energy demand assumptions
• Comparing updated outlooks against prior modeling vintages

The tool allows users to systematically explore how different structural, and policy driven assumptions alter long term market equilibrium.

Model Change Log

This version of the scenario simulator incorporates:

• Program changes adopted under RGGI’s Third Program Review
• Updated allowance budgets and reserve structures
• cCarbon’s revised regional emissions forecast

Together, these updates ensure that the simulator reflects the most current regulatory and emissions landscape. As RGGI moves into its next phase of implementation, scenario-based analysis remains essential. The balance between cap stringency, decarbonization pace, and reserve deployment will determine long term price behavior and compliance costs. The RGGI Carbon Market Scenario Simulator provides a structured foundation for evaluating these dynamics with clarity and analytical rigor.
