SAIC-GM-Wuling builds energy storage power station from retired electric vehicle batteries

In China, SAIC-GM-Wuling recently put into operation Guangxi province’s first cascading energy storage power station utilizing retired electric vehicle batteries at the company’s Baojun base in Liuzhou.


The facility stores wind and solar energy as well as energy from the grid generated during non-peak hours for use by the grid to relieve pressure during peak hours of consumption.

The power station is using old batteries from the development of SAIC-GM-Wuling’s Baojun E100 and E200 electric vehicles. The facility has up to 1,000 kWh of storage capacity, with rated power of 250 kW.



So, the equivalent of the batteries from 45-50 1st gen Nissan leafs.
Not exactly Hoover dam, but a start, I suppose.

Let's say they can sell the power for 10c / kW so $25 / hour when releasing the power and lets say the can do this 4 hours / day - just about enough to pay one person (maybe 2 in China).
You would need 10 of these to take the power from a single 2.3 Mw windmill.
Better scale up.
