Meet the Team Working Group Team 3

Our Goal The Goal of the Market Trial Working Group ( The Team ) is to assist the TSOs in their efforts to ensure that all reasonable preparations are in place to make the Market Trial a success. The level of preparedness will be reflected in the project readiness decision-making ahead of the Market Trial Go/No-Go decision in November. 4

Objectives Team Objectives The main objectives of The Team are to provide feedback in a workshop setting on: Allow the industry to provide input as required into planning activities Provide a platform for discussion of Market Trial scenarios and to provide informed input to the Participant Guidebook Provide an opportunity for industry to discuss the data management approach for Market Trial Allow the industry to discuss the development of the Transition and Cutover Strategy Provide a regular forum for updates on the status and progress of preparations for Market Trial 5

Timelines - Activities

CCQT and PIT Overview Establish initial connection to Market Systems and SEMOpx platform Complete mandatory CCQT scripts 1. CCQT 2. PIT Scripted Execute mandatory PIT scripts to validate Market Participant s ability to interact with Market systems and SEMOpx platform Additional User training / system testing completed by Market Participants (Optional) 3. Unstructured Phase 8

CCQT: Scope CCQT is the process by which the Market Operator verifies that a Market Participant can establish a connection with the market systems and SEMOpx platform. To prove successful connection, the Market Participant will run scripts and confirm that they can access and interact with the market systems as outlined below. For the BM: Retrieval of Daily Trading Day Exchange Rate report (REPT_010) from the MPI Submission of Simple Demand or Generator Offer Data (as applicable) via the MPI for Type 2 communication, followed by a query of the same Offer Data submitted, via Type 3 communication. For the CM: Viewing and downloading the Market Participant Qualification Report from the Capacity Management Platform (CMP), via the CMP application for Type 2 communication For the SEMOpx platform: Day-Ahead and Intraday Auction Platform: EPEX Trading System (ETS) Market Participant exports auction bids from the EPEX Trading System (ETS) client Intraday Continuous Trading Platform: M7 System Market Participant exports orders from the M7 client 9

PIT: Scope PIT verifies that a Market Participant can exchange data with the Balancing Market, Capacity Market, and SEMOpx platform. To facilitate this, PIT is organised into two phases. Scripted Phase The mandatory, initial phase focused on verifying a Market Participant s ability to submit and query data from the market systems. Once all of the mandatory scripts have been successfully completed, the Market Participant is free to proceed with the unstructured PIT test phase. Unstructured Phase The optional phase during which Market Participants can exchange data with the market systems at will and for their own purposes (e.g. system testing or user training). This phase will run from the time starting at Market Participant s successful completion of the PIT scripted phase to the start of Market Trial. 10

CCQT & PIT User Access Party (PY) Participant (PT) Unit Each Market Participant may register multiple users for Balancing Market and Capacity Market system access CCQT & PIT is only required for each Market Participant (PT) once. The nominated Registered User (with access to each participant (PT) for each party will receive a certificate to begin CCQT & PIT. 11

I-SEM Entity Model & PIT Scripts The required PIT scripts to be executed is dependent upon the portfolio of units registered for each Market Participant (PT) An email will be issued to each Party (PY) detailing the required PIT scripts for execution. A Party (PY) will successfully complete PIT following successful completion of all Mandatory PIT scripts by each Participant (PT) within the Party portfolio Party ID Participant ID Participant Name Resource Type CCQT Type PIT Script 1 PIT Script 2 PIT Script X PY_123456 PT_4xxxx Joe Bloggs Windfarm GU Type 2 & Type 3 Yes Yes etc. PY_123456 PT_4xxxx Joe Bloggs Windfarm SU Type 2 & Type 3 Yes N/A etc. PY_123456 PT_5xxxx Joe Bloggs Windfarm GU Type 2 & Type 3 Yes Yes etc. PY_123456 PT_5xxxx Joe Bloggs Windfarm SU Type 2 & Type 3 Yes N/A etc. 12

Next steps: CCQT Preparation to Execution Step: Action: Communication: 1 Participants receive confirmation that they have successfully registered for each of the respective markets as applicable to them I-SEM Registration 2 An email is issued to each party detailing the required PIT scripts for execution I-SEM Testing 3 A Certification Download email is issued from the I-SEM CSS Team which contains the enrolment code, and an email with a Symantec URL which is used to download the PKI client and Cert (The Root Cert as a contingency for the event of the PKI Client not working. It will be installed as part of the PKI client install ) I-SEM Testing & Symantec 4 Participants notify the I-SEM CSS Team of their intent to begin CCQT & PIT Participant POC 5 The same cert is to be used for both the BM and the CM. As such, Participants who have registered for the CM are required to issue certificate details to the I-SEM CSS team as detailed in Section 4.5.3 of the CCQT Guide 6 Participants connect to the test environment and begin and execute CCQT testing N/A Participant POC 13

Risk Register Risk Description There is a Risk that there will be inadequate business (operational) resources in place for Market Trial, Training and Auctions resulting in inadequate preparation and execution which will impact on the Level 1 Plan including Go Live. There is a risk that trial participants will not be able to interface with the market systems. This would require development resources to be deployed to solve the problem which is not planned. Risk Response/Control 1. Resource requirements identified 2. Align resource requirements with the training requirements 3. Multiple workshops held with various business functions as part of the development of a market trial strategy. 4. The Market Trial Plan has been updated. 1. Engage with participants and agree an approach for interface testing. 2. EirGrid have developed a bespoke CCQT document which will be shared with the various participant 3. Continue to meet the participants and support them with their CCQT and PIT type testing. 36
