Or use batteries. Also residential and industrial use will be lower at night. So the existing grid supply may also be enough.

  In many places the contraty is true, peak electricity prices are after sunset, during night.

        > Lot of industry, especialy heavy industry, chemical plants are running 24/7. Right...so they also run during the day (that's what 24/7 means), when everyone else is using electricity. At night they're the only users. Which means less demand at night compared to the day. > see electricity prices in Europe This article is about Pennsylvania. That isn't in Europe.

        I don't see any nighttime prices there. Where do you see that nighttime rates are higher than daytime rates in Pennsylvania?

      PA electricity pricing per hour: * Highest is 14:00 until 18:00 or 21:00 * Lowest is 23:00 or 24:00 until 6:00 https://electricrates.org/pennsylvania/time-of-use/ https://electricrates.org/pennsylvania/time-of-use/

        So nighttime is cheaper than daytime. As logic would dictate.
