    The only completed attempt in last 25 years in US (Vogtle), cost over $15/watt. Before fuel, operations, security, waste disposal plan, and no insurance.

    Turnkey (containers full of batteries) systems in China are under $100/kwh. A possible imported cost of $100/kwh.

    5gw of solar and 19gwh batteries would have higher capacity factor than nuclear, use same transmission infrastructure size, and cost $7/watt. Where winter production is not enough to fill batteries, the batteries can still be charged by wind or peaker plants that can run a bit more efficiently for a continuous time over a day instead of in bursts.
