Can somebody please enlighten me how companies in Washington, or specifically in Seattle, are only paying $0.02/kWh for electricity?
Or is that just the unit of kWh, without demand charges etc?
Does this also scale, say 1MW, 2MW, 5MW etc?
Scale? What do you mean...?
Depending on the electricity provider, they'll often effectively have either progressive or regressive pricing schemes based on how much you use, though they'll sometimes (not always) also offer flat-rate pricing for heavy users. Most companies give a near-useless "base cost" number, or "number to compare," which doesn't factor in taxes, "volume restrictions," cancellation fees, "minimum use" charges, and a whole host of other stuff you can't fit into a cute, single number. When asking if it scales, it's asking if the price for a KWh after, say, 1MWh is consumed, will cost the same or near as a KWh after, say, 50KWh is consumed.
Best way I've found for finding best electricity price is to look up a map of electricity providers for the state (in the US), seeing who claims what territory, then looking them up one-by one and reading through their god-awful "fee schedule books." Some will have a fixed rate which can only be changed annually or some other scheme designed by government bureaucrats, some change each billing cycle, some have "real-time" rates based on nonsense, some charge you based on the time of day you're using your electricity.... some will charge you less if you're old (not kidding) but tack weird restrictions.... this is ignoring the "sign-on bonus" market which exists in some states, which is a whole other clusterfuck of legal nonsense and manipulative advertising (though maybe beneficial if you play it right).
