My electricity is produced by a cooperative. The coop has some 60k participants. And over the year it's managed to build and operate a respectable amount of wind turbines and solar installations, and it's now expanding into district heating and battery storage.

They're producing some 100GWh/year. Which is not half bad, considering they're typically at or below market price and often pay a ~6% dividend.

I think your case is unusual? Co-ops I am familiar with usually don't own generation, they buy power from a regional generator and then provide transmission infrastructure and local services to their (often rural) members.

Maybe with costs for solar dropping more co-ops are looking at adding it at least where it might work to reduce peak demands.
