It is certainly possible, just more expensive. And I'm just saying that one shouldn't mix cost of production and price for the consumer.
It is easier to size the network when the current flows basically in one single direction from power plant to users. When the production is decentralised, you need more transmission lines. You also get more losses in the transmission if you go through more substations.
Big turbines helps to keep a stable frequency on the network despite unpredictable consumption changes. With renewables one need to adjust the frequency. One also need to keep the power factor in track. All of this means extra costly hardware on the grid and extra loss.
