For the results interpretation it is important to remember that demand weighted average deviation is used to measure dispersion between Marginal Prices in European countries and Reference value. Together with additional layer of infrastructure there is possibility to observe how new projects eliminating bottlenecks, creating new capacities between two countries or increasing existing capacity are improving situation. Results of WCF is impacted by the scenarios assumptions such as total demand in EU, demand in specific countries and national production – this is as well influencing different dispersion in comparison of different year and scenario.
The Weighted Marginal Price Deviation measures the dispersion of Marginal Price deltas. The lower Marginal Prices deltas are, the better the Marginal Price convergence. This indicator allows to see direct impact of the infrastructure level, with no interference due to transmission tariffs.
