How did you get 200 MWh? From page 20 of the report: "In summary, retaining existing hydropower capacity and nuclear power capacity (after accounting for planned retirements) and about half of existing fossil fuel capacity, combined with 150 GW of new 4-hour battery storage, is sufficient to meet U.S. electricity demand with a 90% clean grid in 2035, even during periods of low renewable energy generation and/or high demand. Under the 90% Clean case, all existing coal plants are retired by 2035, and no new fossil fuel plants are built beyond those already under construction. During normal periods of generation and demand, wind, solar, and batteries provide 70% of total annual generation, while hydropower and nuclear provide 20%. During periods of high demand and/or low renewable generation, existing natural gas plants (primarily combined-cycle plants) cost-effectively compensate for remaining mismatches between demand and renewables-plus-battery generation—accounting for about 10% of total annual electricity generation, which is about 70% lower than their generation in 2019." 150 GW of batteries with 4-hour discharge is 600,000 MWh. http://www.2035report.com/wp-content/uploads/2020/06/2035-Report.pdf http://www.2035report.com/wp-content/uploads/2020/06/2035-Re...
