Toshiba Will Supply Japan’s Largest Battery Energy Storage System

Toshiba announced Japan’s largest lithium-ion energy storage system – 40 MW and 40 MWh.

40 MWh is like 1,500 electric cars and of couse full power of 40 MW can be provided for up to one hour.

Construction work already began and this large scale battery, consisting of Toshiba’s SCiB cells, will go live in February 2016.

The order for the ESS was placed by Tohoku Electric Power Company to improve supply-demand balance of renewable energy.

“In the Minami-Soma Project, the BESS improves the balance of renewable energy supply and demand. The system stores surplus electricity when supply of renewable energy, whose output fluctuates with weather conditions, exceeds demands, and releases the stored electricity at times of high demand.

Toshiba supplied 40MW-class BESS to Tohoku Electric Power Company for Nishi-Sendai Project in 2014 to regulate frequency changes caused by power output fluctuations. A high evaluation on technical performances of SCiB™, including safety and charge-discharge efficiency, resulted in the order for Minami-Soma Project.

Overseas, Toshiba has supplied BESS to several projects: to subsidiary of Terna S.p.A., an Italian transmission company; for a collaboration with Spain’s Gas Natural Fenosa in an on-site verification testing program for a transportable lithium-ion BESS; and for a large-scale commercial BESS for frequency regulation project in the USA, scheduled to start operation in December this year. Toshiba has also supplied SCiB™ for a 2MW energy storage system project led by the University of Sheffield in the UK.”

The SCiB cells have great cycle life characteristics – 5,000+ cycles. They aren’t suited for EVs due to poor energy density, but otherwise are great for grid storage.

They should install a battery farm like that in the Fukushima area to join the solar PV farms and wind farms that have already been built there. Put that radioactive contaminated land to productive use.

85% of the “mandatory evacuation zone” around Fukushima has a background radiation level less than or equal to that of Denver, Colorado. That is, less than or equal to twice the normal sea-level background radiation level.

A very slightly elevated background level might make the Japanese hysterical with fear, and the Japanese certainly do have more cause than most to fear the dangers of radioactive fallout. But calling the entire evacuation zone “radioactive contaminated land” is merely promoting anti-nuclear and anti-science hysteria.

What the really should do is to start up those temporarily closed nuclear power plants as fast as possible (and build some new ones).
The real disaster is the massive amount of coal that Japan is burning.

You know, Fukushima is still leaking..

Minami-souma is in Fukushima prefecture, but just slightly outside of the exclusion zone. I’m pretty sure construction workers don’t want to spend loads of time in the exclusion zone 😉

40MW and 40MWh means discharge max of 1C, right?

I’m still curious, in utility scale, what the corresponding MWh specs will tend to be when sizing is spec’d in MW.

“Toshiba announced Japan’s largest lithium-ion energy storage system – 40 MW and 40 MWh.”

Wow! Now that’s an impressive amount of grid-level storage capacity. A typical modern power plant puts out about 100 MW of power, so this storage system could put out fully 40% of that, and do it for a full hour. That’s going a long way past merely being able to do a few minutes of peak shaving!

I hope this is a sign of things to come.

I am a little confused to why they limit the power to 40 MW, this system should be able to do 80-160 MW. I am more than sure there is a good reason for it but I’d be interested to know. Maybe efficiency?

What? No hydrogen????


That’s what I said!!!
