What are the different "power ratings" for Superchargers?

Doesn't answer you question but has the kW listed for some.

Are you sure that spreadsheet is accurate? I've heard of folks charging at 120kW at the Burlington, NC location.

Glen Allen is def 120. There was some refs to 133 in Europe but have not heard of any in US. Great sheet though. looks like I can edit it so I did. If this angers anybody let me know.

The original Superchargers were rated at a max of 90 KiloWatts (KW) and the upgrade is to 120 KW. The Tesla Motors Supercharger page has descriptions that, frankly, are simplistic but get the idea across.

I'm pretty sure that spreadsheet is out of date. The Centralia Washington SC is 120 KW. I've heard the the Woodburn, OR is also 120KW.
