I have been following the industry from a distance; construction is accelerating but the prices are still well beyond economical for the scale required for grid stability. And projects are still relatively tiny (<10 GW). Based on the latest projects such as this one in Australia [0], building a grid-scale system will result in energy prices increasing by many multiples. Of course it will get cheaper, but I don't see it being cheap enough that it won't have massive impact on costs (I hope I'm wrong btw).
