What parameters should I assume for a $100 million substation transformer?

[tims.corbett]

Hi All,

I am required to assume some parameters for my research,
For a new transformer worth $100 million for a substation, what likely could be sensible for these

parameters?

Nominal Capacity? (Example 10^5 KW)
Average Repair Cost? ($1 million ?)
Unsupplied energy cost? ($3 kWh ?)
Average Repair time? (1 year?)

Thanks,
Tims

What other sources of information are you looking into to find this?

Google substation costs for a typical 500/230 kV transformer and
http://www.osti.gov/bridge/servlets/purl/645480-vbjaZD/webviewable/645480.pdf

Would $1 million (CAD) be more realistic than $100 million? Would this configuration produce a capacity of 10^5 KW?

He is fairly familiar with high-power transmission and substation equipment.
