Hyundai Electric Secures Order For 150-MW Energy Storage System, Will Surpass Tesla As World’s Largest

JAN 1 2018 BY MARK KANE 18

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.

Let’s not under estimate Hyundai Heavy Industries, They are for sure a force, “N0” small potatoes here ..

150 MW is not the capacity of the battery. It is the power that the batteries and the inverters can supply. We need to know the MWh of this battery.

When I clicked on the source of this story it says 51.5 MWh!

That is not even half the capacity of Tesla’s battery in Australia. But it is a large battery anyway and they will expand it. There is no theoretical limit to expanding. You can always double it.

The 51.5 MWh battery is a different project, for Hyundai Heavy. This 150 MW battery is for Korea Zinc. Other articles say the Korea Zinc battery is 150 MWh, not MW. Hard to say who is right.

You are right. I think they are trying to hide the cost of the kWh. $300 per kWh inverted to AC is the best estimate I can come up with. And I suspect that Tesla’s kWh inverted to AC is cheaper.

Yeah, you keep suspecting ….

And you keep spewing hate.

We’ve all got our niche. 🙂

That’s what I also thought.


A 51MWh battery can’t supply 150MW given current technology. That’s a 3C discharge rate and would likely kill the battery in a couple of 1000 cycles. It is likely that its capacity is also a more comfortable 150MWh.

Say that again? Nissan Leaf has a 24kWh battery can discharge 90kW, so that’s better than 3C. Tesla has 100kWh battery can discharge at something like 600kW, that 6C.
It doesn’t say for how long it sustains 150MW, so 51MWh battery should be able to provide 150MW of power easily, and if it is transitory then all the easier.

It will only be the biggest ESS when it is operational. Until then (or until another larger system comes online beforehand), the Tesla system in Australia will rightfully hold the title for biggest ESS.

I think you mean an ESS based on lithium ion. There are much bigger ESSes out there based on other technologies, like pumped hydro. As of April 2017, the U.S. had over 24.2 GW of rated power in energy storage compared to 1,081 GW of total in service installed generation capacity. Globally, installed energy storage totaled 175.9 GW.

There’s a 400 MW renewable hydrogen storage project in planning here:, but details are scarce.

… but details are scarce.

They could have built about 1700 more IONIQ EVs with that batteries. Waiting time for one is still several months in Europe…

A 200MW / 800MWh vanadium energy storage project is being built already in Dalian, a city in the southern province of Liaoning, by Chinese system manufacturer Rongke Power and UniEnergy Technologies (UET).

Yeah, I don’t think that lithium ion will be the eventual winner for large fixed batteries. Maybe it will be vanadium, there is enough of it.

Yeah. Energy storage systems using li-ion batteries have taken an early lead because of the intense R&D done to lower the cost of such batteries, but I am confident that a cheaper tech which is a better fit to stationary storage will soon overtake li-ion energy storage systems.

There is a vast potential market there for grid stabilization and energy storage, once the per-kWh price comes down somewhat.

Ioniq needs more cow bell….not enough range !!

The more the merrier for 2018
