I pay about 0.05 usd/kWh for power in Iceland. Small scale operation of 25kW, the price includes hosting right next to the micro-hydro plants (one on-grid, one off-grid).

If you go into medium scale (100-200kW, on-grid only) you can expect to pay more, probably closer to 0.08 usd/kWh with transmission and not including hosting.

If you go really big(>10 MW), you can see prices again in the range of 0.05 usd/kWh with transmission.

The low prices exist but they aren't common for smaller operations.
