I. PCR Communication

• PCR organised its first Stakeholder Forum to ESC stakeholders (Associations, NRAs, TSOs, Market Participants)

• 60 physically attended • 59 joined the live online event webcasting

• Primary focus: Euphemia Algorithm

PCR Euphemia Forum 11th of January 2016 in Brussels

CHALLENGES LIMITATIONS IMPROVEMENTS

• Increasing size of the problem

• Increasing number of orders

• Difficult and increasing u er of o - o vex

requirements

Current Euphemia limitations: • The optimality gap

indicator has limited value due to the non-convex nature of the problem

• Anticipated Euphemia performance: local search + multi-threading

• Transparency: o Developing offline computation for

improved optimality gap indicator o Opening dialogue with stakeholders to

develop required transparency indicators

o New products (Thermal Units Orders) to replace Orders currently in production

Scope of the presentation:

• Public Documentation on Euphemia is available for downloaded here

• The PCR Euphemia Forum Materials including:

o The main PCR Stakeholder Forum Presentation o The additional presentation: Non-uniform pricing and thermal orders for the day-ahead and o The link to PCR Euphemia Forum recording valid until February 10th

have been published on the websites of Power Exchanges hosting the Forum:

III. System Upgrades

• Fixing several minor bugs • Higher stability and better data handling • Improvements in messages/logs/errors • Introduction of interface changes needed for implementation of several functionalities

requested by PXs and TSOs

• Improving already implemented functionalities • Expected go-live in Q3 2016

General PCR status linked to system upgrades

• Aiming for better stability of DB due to ending support of Oracle 11.2 • To be implemented in Q1 2016

• Upgrade to Windows 2012 servers • Introduction of new supported browsers • Improvement of the overall support of PCR processes

Upgrade of Oracle 11.2 to Oracle 12.1

New PMB release version 9 – no major changes

Further development expected in 2016

III. Extensions of Members / Geographic Use of PCR Assets

(i.e. New «serviced PX» -> required signature of the Multilateral Liability Agreement-MLA) • 02.12.2015 Croatian PX CROPEX • 03.12.2015 Bulgarian PX IBEX • The Serbian PX SEEPX (only EUPHEMIA to be used) is presently completing the adherence to the
