So help me with the costs here. Adding 25,000 MWh (5,000MW * 5 hours emergency supply) of lithium battery storage would cost... what? As compared to constructing and operating new natural gas plants? I can't get clear numbers that I trust.
- bob1029 7y agoThe largest battery farm on earth is 100MWh and it cost about 90 million dollars. For a 25GWh battery installation, you'd be looking at 22~23 billion dollars using basic linear extrapolation, and I still question if this is enough reserve capacity for our summer peak demand.
- matthewdgreen 7y agoWow. That's quite a lot. I've seen price estimates as low as $387/kWh, which seems to come from NREL [1]. At that price it comes to something like $9.6bn. That's huge, but maybe doable. Alternatively, couldn't Texas just build some HVDC lines to other parts of the US grid to get more stability, as China is doing?
