The largest battery in the world has arrived, and you likely won’t be surprised where it landed: Hebei Province, China. The State Grid Corporation of China (SGCC) and electric car maker BYD--the company that most recently made big headlines a few years back when Warren Buffett’s Berkshire Hathaway took a 10 percent stake--have teamed to create a massive battery array capable of storing 36 megawatt-hours of electricity. That’s enough to power something like 12,000 homes for an hour during a total power failure, and enough for SGCC authorities to declare it the world’s largest energy storage device. The $500 million facility is constructed of arrays of BYD batteries “larger than a football field,” according to an SGCC press release, and they should increase the region’s renewable energy efficiency by up to 10 percent.
It is hooked into 140 megawatts of wind and solar power generation projects as well as a smart grid transmission system.
I have never herd of a battery this Big just to store power?

Sounds like a waste of money.

The purpose of this battery is for power balancing.
Solar and wind power generation is not constant, so to keep up with the constant demand, you need to be able to store some of the power that the wind and solar are generating, in case a cloud goes by, or the wind dies down.
Power balancing is a fairly standard practice for pretty much *EVERY* large scale power generation facility and company.
This is because the LOAD fluctuates on a second by second basis, and the power generation system (Steam Turbine) takes at least 1 minute to respond to changes in power output.
This is one type of power storage for load balancing that is in common usage:
Hydroelectric Pumped Storage.

You see, when you have variable power inputs to the grid, you must have power storage to take up any power that is produced in excess of the load, and to release any power that is needed by load increases.
It's not a weapon.... it's a battery.
