"This is causing issues for policy makers and market operators, who judge that some form of longer duration storage capacity – either in the form of pumped hydro, gas, or some other technology such as solar thermal or compressed air – is required to support the rapid rollout of renewables."

The knockout price was a bid of $US51.59/kWh for a four hour battery (the average was $US59c/kWh), which Energy Storage News says represents a 30 per cent drop from 2024 levels, and others side was a 15 per cent fall from recent record lows.
So is that 51 dollars or 51 cents and an average of 59 dollars or 59 cents?
I do wish journalists would take more care when quoting figures taken from other articles, the article he cites says:
Package 3 (4-hour systems): 2.5 GW/10 GWh, with the most competitive range of CNY 0.37–0.495/Wh ($0.051–$0.068), averaging CNY 0.4249/Wh ($0.059). The lowest bid of CNY 0.37/Wh ($0.051) represents a 30% drop from 2024 levels, setting a new industry record.

I can see that the $US51.59/kWh does appear to be misquoted as it was $US51 in the original article, but the rest looks correct to me having changed from Wh to kWh which probably makes it easier for more readers.

Just for comparison, that 4hr battery average bid price of $59/kWh, compares to ~$220/kWh for the current price of Tesla megapacks*, so it's extremely competitive. Perhaps a great way to gain economies of scale by expanding production, even if you make little to no profit on that specific deal.
That really is an incredible price for a full storage system (not just the cells), and before installation.
*Based on buying 1,000 units of 979MW/3,916MWh packs.
