3 VSD a.s. Východoslovenská distribučná, a.s. Slovakia Company Profile energy utility company member of the RWE Group since 2003 member of innogy Group since 2016 more than points of delivery mission = provide reliable and complex services which correspond to the needs of customers sold more than 3,2 TWh / p.a. average number of employees = 1,000 Shareholders National Property Fund: 51 % innogy South East Europe: 49 % Distribution area km 2 HV Lines km HV & MV substations 60 pcs MV Lines & Cables km MV / LV Distribution stations pcs LV Lines & Cables km 3

4 New Energy Paradigm Conventional Grid => Digital/Smart Grid* Decarbonisation Distributed Generation IoT / Industry 4.0 Transmission Distribution Retail Generation Transmission Distribution Retail Customer Build sufficient grid connected, large and controllable generation to meet demand Balance the system by adjusting generation output to meet demand Over build and then operate blind Deliver and bill with as little customer interaction as possible Little knowledge of how electricity is consumed Bulk Generation Distributed Generation SMART GRID Customer New Entrants REGULATION Allow a rate-of-return on assets for meeting customer service standards Demand Response Microgrids Changing demand patterns Customer Expectations Technology Storage * The Smart Grid is only as smart as the people who build it Regulation Support technical innovation and new commercial arrangements as well as the people who use it.

5 Why do we need Asset Evaluation? I. Data about Asset Condition are part of Asset Management Process Effective Asset Management is: Balancing Act... an integrated set of processes to minimize the life-cycle costs of owning, operating and maintaining assets, at an acceptable level of risk, while continuously delivering established levels of service The asset condition inspection is used to: determine whether an asset is in good or bad shape, and is used to determine what steps, if any, are required in order to improve or repair the asset. There are two types of inspections: the first type determines whether an asset needs to be repaired, and the second determines how much useful life the asset has left. Service Levels RISK Low Costs The inspection results feed into the overall asset condition assessment. Asset condition assessments help an organization plan its capital maintenance and renewal budgets 5

6 Why do we need Asset Evaluation? II. Making hard decision easier With limited capital and operational expenditure (CAPEX/OPEX) budgets, utilities need to make hard decisions about where and when to spend their money to maximize returns on CAPEX while optimizing OPEX. They also can model these activities by evaluating business processes, asset condition and asset degradation to generate asset investment plans based on actual and predictive asset performance long into the future. Key Indicators for Asset Evaluation This allows utilities to effectively optimize costs, risks, opportunities and performance. Aging infrastructure Linking outcomes (KPIs) to actions (investment, policy, operations) Pressure to keep rates low Evaluating risk (environmental, economic, social, political) Regulatory compliance Monitoring service quality in response to investment decisions Quality of service Capturing externalities Improving investment plans Understanding whole life costs not just upfront capital costs Improving control over customer bills Supporting the best practices Improving data quality 6

8 Asset Evaluation Proces I. Workforce Management System in VSD main functionalities Outage management Maintenance activities MV/LV Fundamental data for Asset Evaluation Proces Collection of Asset Condition Status: Good (0) Medium (1) Bad (2) Critical (3) Other activities (new connections, off-takes management, data collection) Data sources IBM MAXIMO SCADA SAP- ISU maintenance outages other Grid Operation and Maintenance MV/LV Implementation system for systematic and fully standardized maintenance activities RWE GROUP/ IDS Scheer

Asset Condition Data Collection part of regular maintenance activities according to Maintenance Order Condition data recalculations executed in IBM Maximo Distribution Transformer Station MV part LV part Building Technology Maintenance Object Functional Units MV-feeder, busbar, switchboard,... LV-switchboard, budbar, fuses,... roof, door, grounding, walls,... transformer, oil, bushings,...

11 GIS - Maximo system integration Data Entry (Data updating) SCADA (Dispatch Centre) GIS Maximo (Grid Maintenance Management) SAP IS-U (Customer Database) SAP PM (Cost Records) SAP FI-AA (Ownership Records) SINCAL (Network Calculation) ETRA (Transformer Management) GIS is a master source of the distribution network of VSD: geographic data + technical records of electricity distribution devices data update process (distribution network) = managed by the GIS department

12 GIS geographic information system in VSD Sophisticated tool for information support a wide spectrum company needs Implementation ArcFM UT v in 2008 Since 2008 integration to others information systems: SAP (PM, IS-U, FI-AA), SCADA, MAXIMO, ETRA, NCS Since 2009 implementation of many custom tools (data visualisation, data providing) In 2014 upgrade GIS to v Awards: ESRI: Special achievement in GIS 2013 GIS-SAP integration in 2010

13 Data collection in GIS geographic data + technical records HV data (110kV) processing of available digital DGN data, orthophoto maps available in 2008 MV data (22kV,10kV) data capture in field ( ) accuracy: submetric internal and external forces LV data (0.4kV) data capture in field ( ) accuracy ±12 cm internal and external forces

14 Data handling: Maximo GIS Achieved results in 2013: technical records of electricity distribution devices (MV) are updated in mobile Maximo devices in field, then are automatically integrated to GIS data integration GIS-MAXIMO enhanced (increase of number MV objects + attributes) any identified changes(geographical or object MV) are processed in following apl.
