It's not just a cash issue. Frequency controls how power moves through
the grid. Power flows from the higher frequency area to the lower
frequency area (not exactly but close enough for this discussion). It
limits the ability to generate power in areas that have excess and loads
transmission lines with power being used to correct frequency.
