Thank you for providing numbers that guide your thinking.

> - $63/kWh [2] installed and serviced for 20 years = $0.063B per GWh

The Lazard source does provide costs for storage on page 44, ranging from about 3x to 6x the cost of that Chinese tender process. Using these numbers gives a rather different picture with storage of between 3.25 days and 1.6 days, insufficient to make solar really work. Alternatively the fair comparison would be within China.

Another data-point would be the UAE's attempt to firm solar; $6B for 1GW effective baseload output with 18GWh of storage [1]. So the cost of Vogtle could buy 6 of these, providing perhaps 3 or 4 days worth of storage.
