A new yardstick is needed –Society‘s Costs of Electricity (SCOE)
Background
• Judging electricity sources only by LCOE stems from ages where electricity production was by definition big-scale and localized at load centers
• With new energy sources entering the scene, this approach falls short.
Objectives
• Analyze supplementary factors in addition to LCOE which affect the true cost of electricity on a macro-economic level
• Provide a comprehensive background for fact-based and objective decisions on the future energy mix
• Base all calculation on acknowledged methods

The decision of the future energy supply should be based on the total cost of energy to society.
