The main limitation AIUI is grid interconnections, i.e. there are a lot of projects in the backlog that can't be built until the utility approves and prepares for it.
> The lists of projects in this process are known as “interconnection queues”. The amount of new electric capacity in these queues is growing dramatically, with over 1,400 gigawatts (GW) of total generation and storage capacity now seeking connection to the grid (over 90% of which is for zero-carbon resources like solar, wind, and battery storage).
