http://www.sgcity.org/utilities/sgrates.phpBTW- Your rates are damn cheap ever after the Customer charge.
their are 12 units in my complex (building b) and dozens of buildings i dont know how many would be on the same grid.
I think you're making this more complicated than it is.
-- Basically, they're saying if you're drawing more than 30kW on your service, you're no longer classified as residential meaning you're either pulling more than 250A @ 120V, or more than 125A @ 240V, or a combination of both.
-- If you receive an electric bill directly from the PUD which varies in amount between billing periods and shows your kWh consumed and bill rate, then you have your own electric meter from your MDU versus a single meter (shared across all units in which your 'rent' would include a fixed rate for electric).
-- Since there are 12 units in your complex, I'll bet 10 BTC that there's 1200A service which is then fed into 12 smaller 100A load centers per MDU with it's own meter. That's a 'typical' setup from a PUD for MDU's.
So in other words, if you do the math, you'll technically *NEVER* be able to pull a load over 30kW.
TL;DR version:What kind of set up would i have to have to go over 30kilowat if there are any math people on to help?
NONE before you'd overload your load center/service feed before you'd be able to pull a load over 30kW.But as an example, my 4x5830 rigs use about 640W. I'd have to run 47 rigs, or 188x5830 GPU's (For 60.16 GH/s) to hit a 30kW draw.

P.S. More fun math...
60.16 GH/s @ Difficulty factor 1805701 gives you 33.5108862792 BTC per day/1.3962869283 BTC per hour.
33.5108862792 BTC @ BTC/USD of $11.37 is $381 per day or $15.88 an hour.
Your electricity costs (before Customer charge) for 30kW is $2.043 USD/hour or $49.032/day.
Assuming your rigs are paid off, that's $13.84/hour of profit which equates to $332 day or $9,960 month assuming near-0 variance.
