That's got to be a typo, or this story is burying the lead. Is pumped hydro really 30% more inefficient than even that figure? Because that would mean it's almost entirely a waste of money for anyone to store energy by this or other means.
If it's $103/GWh, on the other hand, then we're talking about only ~10% overhead on costs.

The article states 30% cheaper, not 30% more efficient. > If it's $103/GWh, on the other hand, then we're talking about only ~10% overhead on costs. The article states $103/kWh, not per GWh. To calculate overhead costs you would need to know life cycle costs which were not disclosed.
