According to data from the Energy Information Administration (EIA), more than 20 gigawatts (GW) of battery capacity have been added to the US electric grid in the last four years. This rapid expansion is equivalent to the production of 20 nuclear reactors and is crucial for averting power disruptions, especially in states that rely significantly on intermittent renewable energy sources such as wind and solar.
The 2 most recent reactors built in the US, the Vogtle reactors 3 and 4 in Georgia, took 14 years at 34 billion dollars. They produce 2.4GW of power together.
For comparison, a 1 GW solar/battery plant opened in nevada this year. It took 2 years from funding to finished construction, and cost 2 billion dollars.
So an equivalent in solar power generation/storage vs nuclear is about 7x faster and 1/8th the cost than nuclear.
Not trying to be a “nuclear shill”, but it is worth mentioning from the article you linked:
The capacity factor of solar is something around 25%, so that 690 MW solar array (even with batteries) produces about as much energy as ~160 MW nuclear… So 7x faster, but the costs are closer than you suggest. Solar is still cheaper because the O&M costs are minimal, but pretending 690 MW solar + 380 MW battery is equivalent to 1 GW nuclear is a bit disingenuous.
