"The spread of projected and reported capital costs is unsurprisingly broad. In Australia the most recent public assessment is
provided by the GenCost2018 report by CSIRO and AEMO.10 It assumes the capital costs for SMR technology is $16,000/kW in
2020 (and experiences no major price decline over time). We note this number is more than double other cost estimates
worldwide. We have sought additional clarification on the basis for this costing. Initial advice is that the number is based on a
GHD estimate for AEMO of costs for a future Gen IV reactor to be constructed in 2035 and not for the type of reactor which
would most likely be deployed in Australia."
Anyhow, that 16k estimate is for power, not for energy... It's unclear over which timespans comparisons are being made (since a lot of it depends for how long power plants will be kept operational... A huge cost is the initial investment).
I've seen energy estimates as low as 30$ per MWh, for Nuclear energy plants built with interest rates of 3%
