The Achievement of the EU Electricity Internal Market through Market Coupling

摘要: The achievement of the internal market for energy is going ahead in EU 15 since a model emerging “coupling national markets electricity”. For about years was made up open to each other through rules access grids while organized pricing kept national. main exception Nordic countries (Sweden, Finland and Denmark plus Norway –not member EU). In this region coupling obtained single Power Exchange being common subsidiary transmission system operators (TSOs). This PX runs Day Ahead zone when grid not constrained splits itself into different areas structural constraints arise. known as “market splitting”. Netherlands, Belgium France did later create less centralized mechanism by “coupling” their three PXs with algorithm coordinating price formation among exchanges. empirical success new has validated it an regional markets. A counter-model been experimented between Germany Denmark. It consisted “volumes” linking quantities offered demanded two exchanges keeping these separated. That experiment failed started work again only elements have introduced. Having now workable models coupling, European Union (at least 15) should be able successfully achieve one layer its soon. However, several further questions are such how bridge all over or integrate more having regulatory frames. approach (known CMU) advocating creating pan-European trading entity mandatory restructuring existing clubbing TSOs extensive harmonization An alternative PCR (“Price Coupling Regions”). allows building demanding coordinate decentralized network. permitting keep flavour requested particular local preferences.
