Summary
To pick the least-cost portfolio that keeps a system reliable, you need to know how each resource contributes as the system changes. Traditional capacity expansion models simplify that part. They fix accreditation curves as inputs and sample a few representative weeks, which misses the extreme weather hours where much of a resource’s value is concentrated.
In this session, Kevin Carden shows how SERVM 2027 takes a different approach. Expansion planning runs inside the same full-fidelity resource adequacy model you already trust. SERVM adds one resource at a time and re-simulates the whole portfolio at each step, so every resource is scored on its real marginal value against the system as it stands.
This session covers:
• Why reliability contribution and economic value change as the portfolio evolves, and where optimization-based models fall short.
• How SERVM’s sequential selection works: candidates are scored on economics, reliability and environmental impact, and selection moves year by year until each year meets its reliability target.
• The full workflow in the product: scenarios, settings, generation and transmission candidates, the execution log, and results including additions, retirements and NPV.
• How every selection comes with its reasoning, so you can answer “why was this built?” for regulators, boards and stakeholders.
Who should attend:
Resource planners, IRP teams, and anyone who uses SERVM reliability results to inform a separate capacity expansion model.
