TagEnergy, in partnership with Tesla, has officially begun construction on France’s largest battery energy storage system (BESS) in Cernay-lès-Reims, located in the department of Marne . The €250 million (C$371M/US$264M) 240MW/480MWh BESS project is a […]
I wish governments would realize that spreading small battery installations around neighborhoods works better than building a huge centralized backup facility like this.
You want both. In fact you want a whole range of different sizes at different locations.
When you design electronics circuits, you place capacitors that smooth the power supply. They’re called “decoupling capacitors” and charge up when the power draw is low, then supply power when the draw is high. The best distribution is lots of small capacitors distributed around, then larger ones distributed less frequently, and bigger ones less frequently again, until you end up with a couple of big ones next to the power supply.
Batteries will become the decoupling capacitors of our national grids.
