Intraday prices in Germany, the region’s biggest market, turned negative during four hours overnight as wind-energy output reached as much as 40 gigawatts, far outstripping demand."
Right now it has a ROI of around 4-5 years. However, this playground isn’t for standard people.
Oh of course, grid scale energy is never for the “normal person”. The point I am making is established fossil-fuel based energy majors do not want any pip-squeak independent startups to start siphoning profit off from their system or possibly making it more efficient or cheaper for the consumer. Vertical integration of regional monopolies is the name of the game.
Domestic scale storage ROIs a lot longer than that, despite 1 kWh going for over 0.3 EUR.
