Plenary Session1 - Energy Market Regulation and Competition: Promoting and Protecting Stakeholders’ Rights in Competitive Energy Markets The Role of Regulation in Reformed Energy Markets Mr Claude Mandil Executive Director, International Energy Agency Many countries have introduced competition into energy markets during the past decade. But markets do not solve all problems. While competitive energy markets have the potential to deliver considerable efficiency benefits, they have created a new player, with a very challenging role: the regulator. As the regulator is supposed to be distinct from the government, there is sometimes the sense that this ends government involvement in the energy sector. Actually, because energy is regarded as an ‘essential service’, governments will always have a responsibility to ensure the efficient outcome of the market. Regulation has traditionally played a key role in increasing transparency, encouraging competition, creating a level playing field, etc. Several important policy challenges have to be addressed by policymakers beyond delivering efficient market-based outcomes: diversification of primary energy sources; ensuring adequate, timely and well located new network investment; ensuring access to reliable and affordable energy services; and ensuring environmentally acceptable outcomes. Successful regulators will need to be responsive to changing policy requirements to ensure that regulation continues to support the development of efficient energy markets. In particular this raises the challenge of balancing the legitimate interests of all stakeholders, including balancing the interests of competitors at each step of the value chain and of users and suppliers through the value chain. When facing these challenges, governments and regulators should avoid two mistakes. The first: playing the role of each other. The second: trying to create greater administrative certainty through more extensive and detailed regulation. More extensive regulation may only increase regulatory uncertainty and the risk of regulatory failure, and may restrict efficient market responses, possibly putting the benefits of competition reform in jeopardy. Instead, governments should to the greatest extent use market mechanisms to achieve their policy goals (e.g. emission permits, green tickets) and rely on competition and robust competitive arrangements to drive the operation and development of efficient energy markets taking into account their policy objectives, with regulation used as a safety net to manage the natural monopoly components and other aspects where markets may not always deliver desirable outcomes. Not only would this provide a least cost regulatory option in many cases, but it might also make the regulatory task easier.
