If you "drill down" that site can come up with some useful info, but price WITHIN A STATE can vary a lot.
Example, most of the Seattle area pays 12 cents/kwh more or less, go 150 miles east into Chelan or Douglas counties and your RESIDENTIAL rate is right about 3 cents/kwh (small business rate almost identical, and "large" business/industrial rates in both counties AND in Grant county next door can get under 2.5).
The largest concentration of cryptocoin mining in the USA is almost definitely in these 3 counties, as they're the 3 LOWEST COST ELECTRIC locations in the US, even for us "small fry".
Grant is the worst for small folks, as the residential and "small" business rates are around 4.6 cents/kwh.
It's hard finding anything less than 5 cents/kwh for INDUSTRIAL level rates anywhere else - and tends to only happen in small pockets near hydropower dams (which is where pretty much all the power generated for the 3 "land of low cost power" counties comes from, each county PUD owns 1 or 2 LARGE Columbia River power dams - note that the Grand Coulee dam (federal owned) is on the border of Grant and Okanogon counties on the Columbia as well, and there are a few other federal-owned large power dams along the Columbia in Washington on the part of the Columbia that is the border between Washington and Oregon).
Note that these figures are "all up" everything included, NOT just the "base rate" - there are places I've lived (like Alliant Energy territory in Iowa) where the base rate is LESS THAN HALF THE FINAL COST most of the year due to the surcharges for stuff like "fuel cost adjustment" and "energy transportation fee" and such.
Con Edison sounds like more of the same, but even worse.
