Euphemia
EUPHEMIA is the market clearing algorithm for the European day-ahead electricity market (SDAC) and the European intraday auctions (SIDC/IDA) and is used jointly by power exchanges across the European Union. It is the property of the power exchanges in the Price Coupling of Regions (PCR) initiative and is being developed and innovated by N-SIDE. EUPHEMIA supports different complex order types and network constraints and operates with high performance and reliability.
Integrating Europe’s energy markets
Euphemia couples Europe’s Internal Energy Market and is ready for further extensions.
Euphemia successfully couples Europe’s energy markets for over 10 years without causing any market failures.
Euphemia enables market participants to express their technical constraints with the right order types.
Support ATC with various constraints (e.g., losses or ramping), PTDF, advanced hybrid coupling, and evolved flowbased.
An algorithm tailored for Europe’s internal energy market
Euphemia is tailored to the needs of the diverse European energy landscape. It supports different types of offers and network models, couples most of the EU, allows for multiple power exchanges being active even within the same bidding zones, and supports 15’, 30′, and 60’ time resolution as foreseen by European regulation. It is a robust and scalable solution that will enable further market extensions and innovative solutions for market participants.
