Metrics Measuring the Economic Efficiency of Power Sources upon Large-scale Introduction of VREs: LCOE and the System LCOE

摘要

This report outlined various metrics “beyond LCOE” that are currently being proposed, while also referringto the relationships between the metrics. As explained, the metrics can generally be described as those for the“total cost (including integration cost),” “market value,” “marginal cost by technology,” and “average cost bytechnology,” though there are slight conceptual differences and similarities between them. The most importantidea among these is the integration cost, or the total cost, calculated for a given energy mix; if this can beestimated accurately with mathematical models or any other measures, it alone can provide very usefulinformation for future energy and environmental policies. Other metrics solely express changes in the total cost.
