    1. Expanded Use of Implicit Auctioning for Congestion Management in Europe Dr. Charles F. Zimmermann Senior consultant, Nexant Inc. European Electricity Markets from a Nordic Perspective Helsinki, 15 November 2007

    2. Objective of this presentation To address the question how national regulatory authorities might cooperate to form a “single market” for electricity In the context of ERGEG’s Regional Electricity Initiative, this is a discussion of “convergence and coherence” To comment on recent trends in the European regions with market splitting and market coupling To provide a introduction the topics covered by the technical paper submitted for this workshop

    3. Why convergence is needed In the context of the Treaty Establishing the European Community, it would appear that a national market should be based on the transposition of EU law into national law For each of the 27 Member States, Plus Norway and Switzerland, Plus the countries in South East Europe that comply with the acquis with regard to the electricity market However, in most countries electricity market liberalization would not be very effective if limited to a national market From a technical viewpoint, only a few European countries (Iceland, Malta, Cyprus) are electric system “islands” Therefore the solution is not to create 29+ national markets

    4. Identification of the European electricity market area The simplest way to define the geographic extent of the market is to look at ETSO membership Norway and Switzerland are inseparable from ETSO Croatia should become a Member soon Turkey looks like a “medium term” candidate Only a tiny bit of Turkey appears on the ETSO map Ukraine and Moldova are “long term” candidates at best The number of bilateral borders is larger than the number of countries, of course Therefore “cross border trade” refers to many borders! See the diagram entitled Reference case winter 2006/2007 notified physical flows ESO EAD (Bulgaria) is the most recent ETSO member - in the diagram, the color for Bulgaria is incorrect
