Agenda • Introduction to the Elhub project • Elhub and the Norwegian power utility market • Developing Elhub coremodels • Information assets developed • Transforming Elhub processes into standard messages • CIM-ebIX harmonisation • Harminization needs

Key aspectsof Elhub processes Processing time Is data available? • Data processing: After-the-fact • Settlement and reconciliation • Reporting • Preliminary and final processing • Business processes: • Future (holding) • Current (beingexecuted) • Past (reversals) Yes No Preliminary processing Final processing Assumed or empiricalvalues Actualmeteredvalues
Introduction to the Elhub project 2016: Elhub go-live • The Elhub is scheduled to go live on 1 October 2016 • The Elhub will be theauthoritativesourceonsuch data in themarket, althoughtheMetered Data Collectorwill be collectingthese from the meters • Statnett will be setting up a data hub (Elhub) for storing collectingmetered data from AMS meters to be installed in themarket by 2019 • The project has currently a public tender for an overall solution for the Elhub • The basis for all ofthefollowinginformation has beensharedwith and in themarket, although most in Norwegian • The considerationsleading up to decisions have beendeveloped in cooperationwithparties in themarket Data responsibilityshift from marketactors to Elhub 2019: AMR transformationcomplete Status: Public tender for solution Models and descriptionsexist in Norwegian Documentsdeveloped in cooperationwithmarketactors
Regional cooperation and influence • Regional harmonization • HNR – Harmonised Nordic Retail market • NBS – Nordic Balance Settlement • Wide consensus oncommonmarket bases an processes • SE, DK, FI, NO • Denmark • Developed a data hub in 2012 • Cooperation provide Elhub with vital experiences • Business processsimilarities • Sweden, Finland • Starting up • Expectsignificant business processsimilarities

- Meteringpoint State Model • Aggregated from: • Physicalstate (meteringpoint) • Contractual binding to Grid Access Provider (DSO) • Contractual binding to Balance Supplier • Combined and simplified for Elhub purposes…
State modelproperties • 2 (3) physicalstates • 3 contractualstates • 10 aggregatedstates • 31 statetransformations
Logicalmarketprocessmessages • Processdescriptionsusing "processcomponents" • "Processcomponents" = logicalmessagestructures • per marketparty, with parameters • 46 processcomponents=> 36 physical Elhub messages • 133 combinations: Processcomponents and parameters
