(Joule 3, 2134–2153; September 18, 2019) In the originally published version of this article, the vertical axis in Figure 4A displayed storage operation data in units of hours of stored energy, mislabeled as MWh. Figure 4A and the analogous supplemental figures (Figures S14–16) have been corrected to present storage operation data in units of MWh. The authors regret this error.Figure 4.

We study systems combining intermittent renewables with storage and other technologies and compare their electricity costs to alternatives. We estimate that in high-resource regions, with optimal resource mixes, low storage energy capacity costs (<$20/kWh) are necessary for cost-competitive, reliable baseload electricity generation. However, when other technologies meet 5% of demand, costs can be halved, even with significantly more expensive storage. Full-Text PDF Open Archive
