PV cheaper than spot market electricity across Europe
The levelized cost of energy produced by large scale PV projects ranges from €24/MWh in southern Spain to €42/MWh in Finland. New research states that is already cheaper than the average spot market electricity price and that the figure for big facilities in southern Spain may fall to €14 in 2030 and €9 in 2050.
