Here in Finland electricity prices can drop to under 1c/kWh due to renewables, basically every time it's sunny and/or windy electricity is practically free (the transfer costs are static though).
A few times the price has actually been negative, people got paid for using electricity due to overproduction =)
In Finland you produce more electricity from nuclear energy, than from hydropower, wind, or solar.
