As a small (20kW) micro hydro, pico grid installation, our local utility deemed our few connected residences, "commercial, demand net metered". The surprising effect (to me) was that we incur demand charges no matter the direction of power flow. So the greater the energy support we provide to a sagging grid the greater the demand charges to us. Not fair!

Depends on many factors. Your water resources, head and flow. The level of your involvement and contributions and so many more items. Hydro is not like solar, no single solution for every site. But if you have > 50 ft head and > 1000 gallons per minute then you should follow up.
