6 2. Introduction 2.1 Purpose This document is designed as a reference for participants when completing the validation and update of Balancing Registration Data (BRD) required for the I-SEM Balancing Market. 2.2 Background The transition from SEM to I-SEM involves ensuring the registration of parties and units for a number of different markets each of which are subject to different governance arrangements. The I-SEM markets being: Forwards (within zone), Financial Transmission Rights, Day Ahead Auctions, Intraday Auctions and Continuous, Balancing and Capacity. In addition the I-SEM includes an Agent of Last Resort Service. The transition from SEM to the I-SEM is not simply a matter of transferring data from the old to new systems. It also involves participants considering how they wish to set themselves up in the I-SEM under a new entity model, providing new registration data and supporting information, as well as potentially amending their existing registration data The first step in the registration process for the I-SEM arrangements involves the registration of Parties, Participants and Units for the Balancing Market. The registration for the Balancing Market needs to occur first as the setup for this market is key to the setup of the other I-SEM markets and services. The I-SEM registration team have issued a set of Balancing Market Registration Data to each Party in the existing SEM. This information has been mapped from the existing SEM entity setups to the new I-SEM entity setups and requires review by participants. Later steps in the Balancing Market registration process will focus on providing supporting information and authorised signatures for agreements. Full details on the Transitional Registration Plan for all markets can be found on the I-SEM website under the registration section here Timelines Parties have until the 31 st January 2017 to validate, amend and return the data spreadsheet to the I-SEM registration team via . The submission will be subject 1 EirGrid Commercial In Confidence. Page 6

7 to the terms of the SEM Trading and Settlement Code, as amended from time to time. The submission must be accompanied by a scanned copy of the form B91 Balancing Data Confirmation provided in Appendix B. This allows the months of November-January for parties to obtain the additional data required and discuss any of their core entity setup requirements (i.e. Party, Participant, Units) with the I-SEM Registration Team and Regulators (if necessary). This approach also means that the bulk of the data required for registration is validated and approved as early as possible. A webinar will be held on the 29 th November to go through the Balancing Registration Data spreadsheet and answer any questions parties may have about the validation process. Should you have any questions the I-SEM registration team can be contacted via I-SEMregistration@sem-o.com or by phone through Claire Breslin on Checklist for Submission The following provides the checklist of documents to be provided to I- SEMregistration@sem-o.com by 31 st January Completed Balancing Registration Data Spreadsheet (updated) Scanned copy of B91 Balancing Data Confirmation Form EirGrid Commercial In Confidence.

8 3. Overview of Balancing Registration Data Spreadsheet 3.1 Spreadsheet Structure The Balancing Registration Data spreadsheet has been provided to each Party for validation and update. Each spreadsheet contains Balancing Registration Data for all Units and Participants under a Party. Where possible data from the SEM has been mapped to the I-SEM. However, there is a need to validate the existing data or include additional data needed for the I-SEM. The following is the structure of the spreadsheet. There are a number of worksheets in the spreadsheet each containing information for the different entities needed to correctly represent the Party and its Units in the I-SEM. The worksheets are outlined in Table 1 below. Table 1 Worksheets in BRD Spreadsheet Tab Name Summary Party Information Participant Information Generator Unit Wind Unit Demand Side Unit Supplier Unit Trading Site Generator Technical Offer Data Demand Technical Offer Data Description Overview of the proposed I-SEM entity model setup, showing also how this relates to the existing SEM setup for the Party Party information Participant level information for all participants under the Party Information on generator units of the party (if required) Information on wind units of the Party (if required) Information on demand side units of the Party (if required) Information on supplier units of the Party (if required) Information on the trading site configurations (if required) Technical offer data for each generator unit (if required) Technical offer data for each demand side unit (if required) EirGrid Commercial In Confidence.

9 3.2 Validation of the Balancing Registration Data The Balancing Registration Data is only a first attempt at mapping the SEM entity setup to that I-SEM entity setup. The I-SEM registration team are not suggesting this is the final setup that the Party must use. Parties need to consider the setup they wish to have for the I-SEM and ensure it is represented in the Balancing Registration Data they submit. The glossary in Appendix C provides descriptions and valid values for each field in the spreadsheet. Please refer to this glossary when completing the validation and update exercise. Some of the data required is only relevant to certain types of units. Details of the relevance of data are also provided in the glossary in Appendix C. The I-SEM registration team are more than happy to provide guidance on the completion of the Balancing Market registration. Each piece of data has three columns associated with it. 1. The Attribute which is the label for the data required and can be used to reference the data in the glossary. 2. The Include in Submission column, which defines what is needed to be done by the Party in completing the validation. a) Confirm implies the value needs to be confirmed by the Party. There may already be a value mapped across from the SEM for this, but this must be validated again by the Party. Where no value is provided then the Party should provide the required information. b) Provide implies the value has not been mapped from the SEM, either because it is not available or may not be up-to-date in the SEM. The Party should provide the required information. 3. The System Name defines the corresponding system name of the attribute as used in the Central Market Systems, and is included for informational purposes only. Where a Party wishes to amend or provide a new value for any data element, it is requested that the cell fill colour is changed to red. This is to help confirm changes provided are legitimate and not made in error. It will also help with the efficient processing of amendments by the I-SEM registration team.

10 3.3 Considerations when completing the Balancing Registration Data Spreadsheet This section provides further information which parties should consider in the process of completing the Balancing Registration Data validation. The information is organised based on the structure of the spreadsheet worksheets. 3.4 Summary The information contained in the Summary tab allows a quick comparison of the differences in the entity setup between the I-SEM and SEM arrangements. As outlined in the Participant Information section below, there are changes to the entity model with the I-SEM. This includes the removal of accounts from the entity structure. 3.5 Party Information The Party information worksheet looks to reconfirm the details relating to the Party. Standard information including address information is included. Information on ACER codes, EIC codes and VAT registration details is also requested. Under the TSC a Party means any person who is a party to the Framework Agreement and is thereby bound by the Code, and shall include its successors and permitted assigns. Refer to the glossary in Appendix C for descriptions of each data field and valid values Address Information Address information for the Party has been left blank in the Balancing Registration Data. We would ask all Parties to provide this information as new for I-SEM. In certain instances the company registered addresses may have changed, or the mailing address for the Party may now be different. Therefore we would request you to provide the latest information. The company address should be the registered company address of the Party. The mailing address should be the address for correspondence with the Party. 3.6 Participant Information The Participant Information worksheet looks to reconfirm the details relating to the Participants the Party has. A Party must have a Participant created for each jurisdiction (ROI or NI) that it has Units registered in. A Party may only register one Participant in each jurisdiction, unless provision for the registration of additional Participants has been expressly approved by the relevant Regulatory Authority. The TSC defines a Participant as: a Party or business division of a Party which at the relevant time has been designated as, or deemed to be, the Participant in relation to any Units which have been registered in accordance with the Code. A reference to a Participant EirGrid Commercial In Confidence. Page 10

11 shall be construed as a reference to the relevant Party in its capacity as the person registered in respect of the relevant Units. Any obligation expressed to be on a Party shall, where appropriate, be construed as an obligation on that Party in respect of each of its Participants Please refer to the glossary in Appendix C for descriptions of each data field and valid values Address Information Address information for the Participant has been left blank in the Balancing Registration Data. We would ask all Parties to provide this information as new for I- SEM. In certain instances the company registered addresses may have changed, or the billing address for the Participant may now be different. Therefore we would request you to provide the latest information. The Participant Address should be the registered company address of the Party or the business unit of the Party. The Billing Address should be the address for invoicing of the Participant Entity Model Changes The entity model for the I-SEM is different to that for the SEM. The key difference is that accounts are no longer relevant in the I-SEM. Instead all Units are linked directly to the Participant. EirGrid Commercial In Confidence. Page 11

12 Figure 1: Old SEM Entity Model Figure 2: New I-SEM Entity Model Implications of I-SEM Entity Model The implications of the new I-SEM entity model are: The existing provision that a Party may have only one Participant per jurisdiction is maintained. RA approval is required to have more than one per jurisdiction. Participant is the level at which credit cover is calculated and must be posted (unless an SRA is in place where the Participant is acting as a Secondary Participant to the SRA). For further information on SRAs, see the TSC and related Agreed Procedure. Parties receive one Settlement Document for payments and charges related to all Units that are under the same Participant. Where payments are due to Participants, a single bank account is specified per Participant for making the payment into. EirGrid Commercial In Confidence. Page 12

13 3.6.4 Naming Conventions The naming standard to be used for the I-SEM is similar to that used for the SEM. Table 2 Naming Conventions Role Party Participant Trading Site Supplier Unit (also for Trading Site Supplier Units and Associated Supplier Units) Generator Unit Demand Side Unit Assetless Unit Trading Unit Naming Convention PY_nnnnnn PT_nnnnnn TS_nnnnnn SU_nnnnnn GU_nnnnnn DSU_nnnnnn AU_nnnnnn TU_nnnnnn Mapping of Accounts to Participants The PT naming standard is to be retained for the I-SEM. However, given the accounts are no longer relevant the PT naming standard will now apply correctly to the Participant. Note: the change in naming for the Participant in Figure 2 above. In mapping the existing SEM entities to the new I-SEM entities the lowest numbered PT number was of the accounts used for the naming of the Participant. e.g. Participant (CP_400005) with Accounts (PT_ and PT_400002) has become Participant (PT_400001) in I-SEM. 3.7 Generator Unit The Generator Unit worksheet contains data pertaining to any Generator Units registered to the Party. This information, where applicable, has been taken directly from the existing approved SEM records. This Generator Unit worksheet contains information relating to standard Generator Units only, any other types of Unit are covered under separate worksheets (e.g. Wind, Demand Side, and Supplier). Refer to the glossary in Appendix C for descriptions of each data field and valid values. EirGrid Commercial In Confidence. Page 13

14 3.7.1 Interconnector Units With the changes in the market arrangements for I-SEM, the registration of Interconnector Units who bid into the market for volumes to be traded on the interconnector is no longer relevant. Therefore, details on these Interconnector Units have not been mapped from the SEM to I-SEM, and will not appear in the Balancing Registration Data. Participants who have historically only had Interconnector Units will need to determine if they wish to remain active in the I-SEM and in what capacity. The I-SEM registration team are happy to discuss this situation with existing Parties who have registered Interconnector Units Assetless Units Assetless Units are a new form of unit related to the I-SEM market. They represent a Participant s activities in the Balancing Market which is not related to a physical Generator, an item of Dispatchable plant, or a Supplier Unit. They trade in the exante markets (Day Ahead and Intraday) with the subsequent settlement of any imbalances in the Balancing Market. Assetless Units are not an existing type of unit in the SEM. Therefore there has been no mapping of Assetless Units included in the Balancing Registration Data. Parties who may be interested in setting up an Assetless Trading Unit for the purposes of trading in the I-SEM should contact the I-SEM registration team before the 10 th January 2017 to discuss their requirements. 3.8 Wind Unit The Wind Unit worksheet contains data pertaining to any wind power Generator Units registered to the Party. This information, where applicable, has been taken directly from the existing approved SEM records. This Wind Unit worksheet contains information relating to Wind Units only; any other types of units are covered under separate worksheets (e.g. Generator, Demand Side, and Supplier). Refer to the glossary in Appendix C for descriptions of each data field and valid values. 3.9 Demand Side Unit The Demand Side Unit worksheet contains data pertaining to any Demand Side Units registered to the Party. This information, where applicable, has been taken directly from the existing approved SEM records. This Demand Side Unit worksheet contains information relating to Demand Side Units only; any other types of units are covered under separate worksheets (e.g. Generator, Wind, and Supplier). As Participants registering Demand Side Units are required to register a Trading Site Supplier Unit they must also ensure the relevant Supplier Unit and Trading Site worksheets are also completed. EirGrid Commercial In Confidence. Page 14

15 Refer to the glossary in Appendix C for descriptions of each data field and valid values Supplier Unit The Supplier Unit worksheet contains data pertaining to any Supplier Units registered to the Party. This information, where applicable, has been taken directly from the existing approved SEM records. If another Party records the Trading Site demand for your Generator Unit (i.e.. an Associated Supplier Unit), then this worksheet is not relevant. This Supplier Unit worksheet contains information relating to Supplier Units only; any other types of units are covered under separate worksheets (e.g. Generator, Wind, and Demand Side). Refer to the glossary in Appendix C for descriptions of each data field and valid values Trading Site The entity setup for the Balancing Market requires that Generator Units and Demand Side Units (excluding Pump Storage Units, Battery Storage Units and Assetless Units) setup a Trading Site. A Trading Site is defined in the TSC as one or more Generator Units and at most one Trading Site Supplier Unit of which, with the exception of Trading Sites that contain Generator Units that are Aggregated Generator Units or Demand Side Units, all Generator Units are covered by a single Connection Agreement, or in the event that no Connection Agreement exists, all such Units are located on a Contiguous The TSC mandates that certain types of units have certain Trading Site setups. The most common Trading Site setups are provided in Appendix A and relate to individual Generator Units, multiple Generator Units on the one Trading Site, Demand Side Units, Aggregated Generator Units and Autoproducers. In the Trading Site worksheet, the Maximum Export Capacity value should equal to the Maximum Export Capacity of all the Generator Units registered under that Trading Site Trading Site Supply Units A Trading Site Supply Unit (TSSU) is defined in the TSC as: a Supplier Unit that contains only the Demand within a Trading Site, and is settled on a net basis against the Generator Units on that Trading Site under the rules specified in the Code. In the SEM the use of TSSU was common as it had certain advantages. These advantages are outlined in Appendix A. However, under the I-SEM these advantages no longer apply and the use of TSSUs is really only necessary for Autoproducers where the import can be significant when on-site Generator Units are not operating EirGrid Commercial In Confidence. Page 15

16 In the Balancing Registration Data provided these TSSUs have been maintained in the entity setup. Participants are requested to consider whether they still wish to maintain the TSSUs for their entity setup, or whether they wish to change to an Associated Supply Unit. Should a Participant with a Trading Site Supplier Unit, wise to change to an Associated Supplier Unit then you are required to contact the relevant retail market operator as there may be additional retail registration requirements that must be completed to facilitate this change in Supplier Unit type. The alternative to having a TSSU on a Trading Site is to have an Associated Supply Unit assigned to the Trading Site Associated Supplier Units An Associated Supplier Unit is a Supplier Unit which is recorded to a Trading Site but may also contain demand outside that Trading Site and has its demand settled on a gross basis with the Generator Unit(s) on that Trading Site. Whereas a Trading Site Supplier Unit can only record demand for a single Trading Site, an Associated Supplier Unit can record other demand also. An Associated Supplier Unit may be registered to record the demand associated with a Participant s market registered Generator Units, or may be a Supplier Unit associated with another Participant with whom they have a supply agreement. For existing Generator Units operating under a Trading Site, the Party is required to confirm if the existing recorded Supplier Unit still records the demand on that Trading Site. If not, then please specify the correct Supplier Unit ID in the spreadsheet, using the appropriate change markings Generator Technical Offer Data The Generator Technical Offer data worksheet contains the current approved SEM technical offer data for each Generator Unit. This information should not be changed and is included for informational purposes only. If this information is incorrect and needs amended, then it should go through the existing SEM process for updating Generator Technical Offer Data. The exception to this is a pump parameters element which includes new TOD and should be provided if know by pump storage units. The intention is that closer to the market trail a new version of the approved TOD data for each Generator will be taken from the existing SEM systems and used as the basis for market trial and go-live. Note: This information is not required to be completed for Wind Units. Default values of zero will be submitted by the Market Operator. EirGrid Commercial In Confidence. Page 16

17 3.13 Demand Technical Offer Data The Demand Technical Offer data worksheet contains the current approved SEM technical offer data for each Demand Side Unit. This information should not be changed and is included for informational purposes only. If this information is not correct and needs amended, then it should go through the existing SEM process for updating Demand Technical Offer Data. The intention is that closer to the market trail a new version of the approved TOD data for each Demand Side Unit will be taken from the existing SEM systems and used as the basis for market trial and go-live. EirGrid Commercial In Confidence. Page 17

18 4. Relationship between Balancing and Capacity There are strong links between the Party, Participant and Unit setup in the I-SEM Balancing and Capacity Market. Under TSC and Capacity Market Code (CMC) rules the Party, Participant and Units defined must be the same in both markets. Hence, the need to define Balancing Market entity setup early on as it has implications on the Capacity Market which will go-live for auctions before the main I-SEM Go-Live. As the Party, Participants and Units are the same for Balancing and Capacity Markets this means that: the Settlement Documents produced are designed to incorporate both balancing and capacity settlement the bank account used for payments to Participants is the same for both balancing and capacity payments collateral requirements for the Capacity Market are combined with the Balancing Market EirGrid Commercial In Confidence. Page 18

19 5. Registration Data to be Submitted Later There is other registration data that is not being collected as part of this Balancing Registration Data validation exercise. This information is not needed for the initial validation of the I-SEM and may only be determined at a later date - so has not been asked for here. Examples include: Commercial Offer Data This will be submitted by parties on behalf of their Generator Units and Demand Side Units directly into the market trial system Settlement Reallocation Agreements these agreements will be confirmed at a later date through the signing of formal legal documentation User Setup this will be requested as part of the submission of the balancing supporting information which is due to occur by the middle of March 2017 Other supporting documentation and information may also be required. Forms will be published in mid-january 2017 to define what this supporting information is. Examples could include: TSC Framework Agreement - signed Schedule of Signatories allowing delegation of authorised signatories Party Administrative User Authorisation nomination of a user who has authorisation to create and amend user access for the Party to the market systems. Form of Authority for TSC, if not able to grandfather the arrangements. User Access Setup of users needing access to the I-SEM systems. Remit Form authorisations to submit information to REMIT on behalf of Parties. Banking Information Confirmation and authorisation of required banking information to be used for administering payments. Collateral Information Setting up required collateral arrangements for the provision of credit cover. 5.1 Changes to Balancing Registration Data If changes are needed to the Balancing Registration Data after the submission deadline of the 31 st January 2017, then the method of amendment will be dependent on the type of data and whether the changing is also being effected in the current SEM registration. The methods are: 1. Technical Offer Data - If the change relates to Technical Offer Data then closer to the market trial a new version of the approved TOD data for each Generator or Demand Side Unit will be taken from the existing SEM systems and used as the basis for market trial and go-live. 2. Registration data needing update for existing SEM as well - If changes are being effected in the existing SEM registration, then as part of the EirGrid Commercial In Confidence. Page 19

20 amendment process there will be an additional step included to ensure the I- SEM registration data is reviewed and updated as appropriate. 3. Registration data needing update for I-SEM only - If the change is not impacting on the existing SEM registration then Parties will need to inform the I-SEM registration team using the enduring I-SEM agreed procedures of the update required. EirGrid Commercial In Confidence. Page 20

21 6. Appendices 6.1 Appendix A: Trading Site Supply Units Benefits of TSSUs in the SEM, but not in the I-SEM In the SEM some Participants have configured their Trading Sites to use Trading Site Supply Units (TSSUs). This has historically been an advantage in the SEM expost market as when a site is importing (on the TSSU), the market availability for the generators is set by taking account of the site import. This is on the basis that the generators on the site can deliver the import requirement before the site begins to export. Rules for calculation of actual availability take account of the site import and can allocate this as an available quantity for the ex-post market. Where this availability is below the minimum availability of the unit, the MSP resets the availability for the ex-post scheduling to the minimum availability. Thus, a unit which is serving a small house load quantity of 0.5MW can have an availability set to the unit s min availability which is likely to be a higher figure. This situation is less relevant for the I-SEM, given that access to the market in the I- SEM will be through the ex-ante market. Therefore the link between the Firm Access Quantity (FAQ) of the site, the ex-post demand on the site and what is available to the market no longer exists. Participants will have to determine how much they wish to offer to the ex-ante market; the TSOs will schedule the unit on the basis of system conditions and the ex-post settlement will apply relevant prices to firm and non-firm quantities for units as appropriate. The ex-post settlement calculation does still account for on-site demand in determination of the level to which each a generator is firm and this can therefore have an impact on the price against which TSO actions are settled; however, the overall impact may be less than in the SEM where a generator stands to get a significantly higher access to the ex-post market. As an example, in the SEM a small house load of 0.5MW can result in payments on the basis of min-availability of say 20MW, whereas in the I-SEM a small house load of 0.5MW will result in differences in payments on the basis of 0.5MW. In addition, in having a TSSU in place the participant will incur credit cover requirements and need to pay market operator charges for minimal benefit Mandated Trading Site Configurations The following provides the Trading Site configurations that must be maintained under the TSC for different unit types and Trading Site arrangements Single Generator Units All Generator Units and Demand Site Units, with the exception of Pump Storage Units, Battery Storage Units and Assetless Units, must have a Trading Site setup. In the examples below PT refers to the related Participant. Where there is only one unit on the Trading Site the setup would be simply: EirGrid Commercial In Confidence. Page 21

22 Figure 3: Trading Site Configuration Single Generator Multiple Generator Units on the same Trading Site (Option 1) For multiple generation units on the same Trading Site there are two options for Trading Site setup. Option 1 below uses an Associated Supplier Unit. In this case the Associated Supplier Unit is based on a supply contract taken up with another Participant. However, the same setup could be achieved with the Supplier Unit belonging to Participant 1 (PT1) as well. Figure 4: Trading Site Configuration Multiple Generators (Option 1) Please refer to section Benefits of TSSUs in the SEM, but not in the I-SEM for further information in deciding which option is most appropriate Multiple Generator Units on the same Trading Site (Option 2) For multiple Generator Units on the same Trading Site the second option is to use a Trading Site Supply Unit rather than an Associated Supplier Unit Figure 5: Trading Site Configuration Multiple Generators (Option 2) EirGrid Commercial In Confidence. Page 22

23 Demand Side Units TSC rules require that Demand Side Units must have a Trading Site Supply Unit included in the Trading Site configuration. The setup of Demand Side Units is provided below. Figure 6: Trading Site Configuration Demand Side Units Aggregated Generation Units TSC rules require that Aggregated Generation Units must have an Associated Supplier Unit included in the Trading Site configuration. The setup of an Aggregated Generation Unit is provided below. Figure 7: Trading Site Configuration Aggregated Generation Units Autoproducers Autoproducers are large industrial sites with high demand requirements, but also have significant generation capabilities. At certain times their onsite demand will be less than their generation and hence they will be able to generate power that can be supplied to the I-SEM. Under the TSC, Autoproducers may register a Trading Unit (TU) as part of their Trading Site configuration to facilitate participation in the day-ahead and intraday markets as a single Unit for all Generator Units.
