Move over Tesla. There will soon be an even bigger battery energy storage system in place.

Tesla Powerpack energy storage system (100 MW/129 MWh) in South Australia

Hyundai Heavy Industries’ Electric Systems Division recently received an order for a 150 MW battery energy storage facility from Korea Zinc Inc. in South Korea.

The capacity wasn't disclosed, but the 150 MW deserves the title of the world's new biggest ESS - in terms of power level anyway, as the recently opened Tesla ESS in Australia was rated at 100 MW.

Cost of the project is estimated at 50 billion won ($45 million).

Some think that energy storage will become an even greater market for lithium-ion batteries than automotive industry, but as of today it's only a small fraction. The largest projects worldwide are smaller than the combined batteries for 1,000-2,000 cars with the biggest packs. Baby steps.
