Giant Batteries Are Transforming the Way the U.S. Uses Electricity

They’re delivering solar power after dark in California and helping to stabilize grids in other states. And the technology is expanding rapidly.

    The issue with batteries currently is that they aren’t able to ramp up and down instantly despite what it may seem

    Large battery systems are already in use as base load in Australia. They absolutely can ramp up and down and can do so faster than nuclear because nuclear is just a steam generator. Large generators have inertia requiring a minimum of 10 minutes to speed up when already fully operational, otherwise 1-12 hours.

      You’re correct I had misremembered and had to revisit my sources. I was not able to find sufficient data support my claim that batteries have any inherent delay.

      However, In Australia which gets relatively consistent wind and solar I think it is more beneficial to invest in batteries.

      Conversely in North America where the efficacy of wind and solar vary significantly by season and local climate, it is necessary to oversize generation and use batteries needed in order to ensure grid stability during periods of high demand and low supply.

      This is attainable on the small scale and absolutely could be used to stabilize a grid with a steady backbone provided by something like nuclear or natural gas.

      However without the stabilization of another steady source the cost quickly becomes unfavorable if you wish to maintain absolute grid stability as excessive over building is necessary with the highly volatile production.

      I do think this is shifting more in the favor of battery storage with every new advancement.

      My apologies for my previous misinformation it has been a long time since I’ve visited this topic.
