.23 cents per kwh? really?? as in less than a quarter of a penny per kwh? can that even be true?
it's not. It's $0.023 per kWh. Closer to 3 cents with taxes & other charges.
Could they be near an old nuclear reactor power station? I think rates are low near Three Mile Island and others. I recall on LI the Shoreham reactor saw very low rates in the immediate area but any meltdown threatened a very wide area - so the low rates were to influence locals not to compensate for threat - sorry, I get carried away....
unlikely. most of it is in washington, powered by hydro dams.
nuclear power is generally built close to the cities it will power. hydro dams are often located a distance from any major populations due to the steep terrain and large rivers/streams they need to create power. Its reasonably common for the cheapest electrical rates (and thus datacenters) to be found near these facilities in otherwise largely-undeveloped areas
