Problem: A 21-kW substation was built in County A in Texas for 1.4 million dollars in 2015. The same substation would cost 1.6 million to build in 2022. County B, a neighboring county, wants to build an 18-kW substation in 2022. Assume a power sizing exponent of .85 and estimate the cost of construction for the 18-kW substation.
