Electricity investment costs and stranded asset calculation by Plutus

[Shukla02Nikita]

@mengqi-z Hi, I am Nikita Shukla, an energy modeling professional based in New Delhi, India. I am interested in understanding the specific methodology employed to calculate electricity investment costs and stranded asset valuation in Plutus. I am also curious about the literature and references that informed this process.

I assume you're aware that there's a paper documenting Plutus, but just in case: https://joss.theoj.org/papers/10.21105/joss.03212 The key assumptions behind the calculations performed are the capacity factor and overnight capital cost, both of which come from NREL's Annual Technology Baseline datasets: https://atb.nrel.gov/electricity/2023/index For estimating stranded assets, GCAM has an endogenous "profit-shutdown-decider" which reduces the output of cohorts of power plants whose operating costs exceed the revenues from selling electricity.
