These must be some big batteries

Tohoku Electric to build power storage facility

updated at 8:39 UTC, Jun. 18

Tohoku Electric Power Company, the electric utility in northeastern Japan, is to build a power storage facility to prepare for possible power shortages in disaster-stricken areas. The facility is likely to be the largest of its kind in Japan.

The new facility, to be built at a thermal power plant in Akita Prefecture, will have 40 rechargeable batteries, which are enough to store a day's supply of electricity for 50,000 households. The batteries will be charged at night so that they are ready to supply power when demand is high. The total output will be 80,000 kilowatts, which will be the highest in Japan.

40 rechargeable batteries, which are enough to store a day's supply of electricity for 50,000 households. Geebuz! Never heard of anything like this before. All we have for this kind of stuff around here are small natural gas operated "peaker", electrical generating stations that kick in for periods of higher than normal usage.

1. The article says 80,000 kilowatts

I'm guessing they meant kilowatt hours?

Wonder what sort of tech they plan on using. Hard to image them using arrays of lead acids for that.

2. It sounds as if they are talking instantaneous power output

which would be in watts.
