They’ve got a quite unusual stove that’s got a large battery in it so that it can operate when the power is off, and doesn’t need the installation of a 240v power connection. This avoids the cost of an electrical retrofit of old apartment buildings, which otherwise costs far more.
If you’ve already got your home wired for 240v, you can get an induction stove for far less.
These battery-equipped stoves are expensive right now because they’re being made in quite small numbers. The parts needed are coming down in price quite rapidly, so I expect to see them sold in the $2000/unit price range within a few years.
I bought a gas stove 2 years ago and replaced electric. I did it because I needed to free up the circuit for other things and it was cheaper to replace the stove than get a upgraded panel. I ran the gas line myself but I won’t do a electrical upgrade myself. I have automatic exhaust when the stove turns on so its not much of a deal.
That’s why NYC is using induction stoves with batteries that can trickle charge over a day
