Had a look at a recent bill, which includes usage for the billed month and what the next bill will be, and we are paying ¥26 per kilowatt.
There are some breakdowns--1段, 2段, 3段--where cost changes based on usage levels, but I'm not going there.
Ours is not an "all denka" home (all electric--we also use kerosene and city gas), and I think there's a discount for those all-electric connections. Also, that service offers a heavy discount for overnight usage, and those homes recharge their "batteries" then--either heating their entire hot water for the next day, or heating that along with hot water that will be circulated for heat during the following day. (or heating one of the euro-type heaters filled with bricks, which retain the heat for the following day)
There's probably not much solar in Alaska :emoji_wink:, but there are also guaranteed rates here for what the power company will pay you for your solar generation. It depends on the size of your system (above or below about 10 kilowatts), but you get more or less per kw (depending on system size), guaranteed for 10 or 20 years. IIRC, and I could be wrong, but I think for the smaller, under 10kw system, you get something like ¥20/kw.
The other electricity cost is the 2% or so that they tack onto my yearly tax bill to pay for reconstruction from the 3/11 triple meltdown. Add that in as a part of the cost for power, and the per-kw rate would be higher.
