  2. EUPHEMIA - Background  EUPHEMIA is the algorithm used for day-ahead market coupling across Europe;  P an Eu ropean H ybrid E lectricity M arket I ntegration A lgorithm;  Initiative of seven Power Exchanges: APX, Belpex, EPEX SPOT, GME, Nord Pool Spot, OMIE and OTE, who have developed a price based market coupling algorithm for cross border trades between their market areas;  Covers the day-ahead electricity markets in Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Italy, Latvia, Lithuania, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and UK;  Initiative started in 2009, and the PCR parties signed the PCR Cooperation Agreement and PCR Co-ownership Agreement in June 2012

  3. EUPHEMIA - Background Markets included in PCR - 2872 TWh Markets associate members of PCR Markets that could join next as part of an agreed European roadmap

  4. EUPHEMIA - Background  PCR is based on three main principles:  a single algorithm,  robust operation and  individual Power Exchange accountability.  The common algorithm will give a fair and transparent determination of day-ahead electricity prices and allocate cross borders capacity.  The PCR process is based on a sharing of data, providing a robust and resilient operation.  The PCR Broker and Matcher service enable exchange of anonymised orders and area-to- area transmission capacities among the Power Exchanges  Euphemia will be used to calculate electricity prices across Europe;  It will also optimise the overall welfare and increase transparency of prices and flows

EUPHEMIA - Background  For the power market: Most competitive price will arise & Overall welfare increases Market A Market B Isolated Coupled Markets Markets P ( € /MWh) P ( € /MWh) Price convergence Price Export Differences Import PB PA’ PB’ PA QA’ QA QB QB’ Q (MWh) Q (MWh)  For TSOs: Efficient capacity allocation

  8. EUPHEMIA – Testing  SEMO signed up as associate members of PCR  Have had discussions with algorithm working group (ALWG) members  Progressed our understanding of the different order types and how these could be used  Requested of the PCR Steering Committee that testing be facilitated  Testing for I-SEM was approved at the PCR Steering Committee in June  Other priority projects taking major focus ( Italian Borders coupling )  Despite this, we have progressed with members of the ALWG

  9. EUPHEMIA – Testing  First phase of testing to be completed by SEMO  This is the “conceptual test” phase  Objective of this phase: to represent a SEM generator’s commercial submission in EUPHEMIA format  To test three days of the SEM using actual input data from the EA1 schedule  To assess the different order types that can be employed  Each day has been set up using either linked block orders, exclusive group orders or minimum income condition orders

  10. EUPHEMIA - Testing  Used technical characteristics to create a minute by minute generator profile

  11. EUPHEMIA - Testing  …and from this, create an hourly average output

  12. EUPHEMIA - Testing  …and using price/quantity pairs, create parent child blocks 300 300 250 250 200 200 150 150 100 100 50 50 0 0 1 2 3 4 5 6 7 8 9 10 11 Parent A Child A - Parent B Child B - Parent C Child C - Parent D Child D - Parent E Child E Ouput  Applying “uplift” costs into the parent block allows cheaper child blocks to be in merit

  13. EUPHEMIA - Testing  Can use linked block orders either side of the parent block to extend the running time of a generator G Great Great Great G Great Grand Grand Grand Grand Grand Child 1 Child 2 Child 3 Child 1 Child 1 Great Great Grand Grand Grand Child 1 Grand Child 4 Child 2 Child 4 Child 2 Grand Grand Child 3 Parent Child 2 Child 5 Child 3

  14. EUPHEMIA - Testing  Alternative can be to use minimum income condition ( MIC )  Simple price quantity pairs but with “uplift” costs noted separately  Ensures unit does not run when at a loss  Exclusive groups allow generator to submit multiple running options  Exclusive Groups can have the generator start/end at any time, with a different order for every start and end time  Acceptance ratio values used to ensure only one feasible set is selected

  15. EUPHEMIA - Testing  Data has been provided to the ALWG  Has been tested and adjusted for formatting  First tests are SEM in isolation  Expecting first results shortly  We expect that these will lead to changes in how we submit to the algorithm  We don’t expect to have got it right first time!  Experience of the SEM implementation taught us this  We expect a number of iterations with the ALWG before we’re satisfied

  16. EUPHEMIA - Testing  Next phase of testing will be “commercial tests”  We propose the following approach – 1. Workshop 1: Initiation – publication of SEMO report on EUPHEMIA and results of conceptual testing 2. Workshop 2: Testing readiness – SEMO to present on the methods used in the conceptual testing phase & to provide template workbooks to participants based on PX interfaces into which data can be submitted 3. Further interaction: envisage more interaction between SEMO and participants in the finalisation of testing data

  17. EUPHEMIA - Testing  Next phase of testing will be “commercial tests”  We propose the following approach – 4. Test case creation: conversion of participant data into EUPHEMIA input format 5. Test execution: submission of test cases to the ALWG, review of test results, circulation of results and issue management (re-run of tests if required) 6. Workshop 3: presentation of results of the commercial testing.

  18. EUPHEMIA – Next Steps  SEMO will develop a timetable for the commercial testing phase  In discussion with the ALWG around support for this work  This is dependent on the successful implementation of the Italian Borders coupling in February 2015  Participants to consider –  Do they support this proposal?  How much testing should be done ( one month, one year )?  How many iterations of commercial testing will be needed?
