Abstract

Abstract: Intraday markets for electricity allow for trading of energy until shortly before the period of delivery. This offers market participants a possibility to reduce their expected imbalances and to offer own unused flexibility. Because this form of distributed balancing before the period of delivery can be profitable for market participants as well as beneficial for system operations, intraday trading is expected to gain more importance in future, especially with increasing shares of variable renewable energy sources in the generation mix. So far, intraday markets are still a research field with many open questions. This paper contributes by a first analysis of intraday trades onElbas, one of the European intraday markets. The analysis gives a detailed picture on trading activity and price development and is intended to improve understanding of continuous intraday trading. Findings include that trading activity differs significantly between price zones, that most trades occur in the last hours before gate closure and that market participants have to handle substantial price variations during the trading period. The paper also investigates the imbalance settlement rules in the Nordic countries and studies which effects one- and two-price imbalance settlement systems have on the market participants' profitability of intraday trading. Abstract : Highlights: Insights into intraday trading: trading activity and price development. Special focus is on characteristics of continuous trading. Intrinsic problems in the Nordic imbalance pricing scheme are discussed. Implications regarding balancing of generation from vRES.
