Elektrilevi Distribution Network
Asset base:› Connection points 660 595› Primary substations 265› MV/LV substations 23 386 › Secondary (switching)
substations 217› 35(110)kV transformers 186(16)
› 6-35kV lines 29 346 km› cable lines 8 122 km› overhead cables 1 664 km› overhead lines 19 560 km
› 0,4kV lines 34 715 km› cable lines 9 928 km› overhead cables 13 386 km› overhead lines 11 401 km
Total of lines 64 061 km
Key drivers: regulationsElectricity market is opened for all customers since 1. January 201381% from all connections do have direct contract with electricity seller.
Estonia’s legislation is in accordance with the 2020 goal which states that all electricity meters must be replaced with smart meters by January 2017.
Fulfilment in two stages› Metering Points above 63A must have smart meter from 1. January 2013› Metering Points up to 63A must have smart meter from 1. January 2017
Legislation regarding metering were put in place July 2010
Key drivers/KPI benefits for DSOAsset base for electricity meters was old, 44% from total meters went off from
verification 2012-2016. Investments and re-verification was needed.
Reduction of losses, 2010 – 6,12% 2015 actual – 4,75%. Expected level for 2018 was 4,85%.
Reduced costs on meter read handling
Operational costs reduction (on/off )

Project scopePrime Contractor› Responsibility for turn-key Project execution (625 000 MP-s) › Coordination between all parties: Elektrilevi, Solution provider,
Meter HW provider, installers etc.
Rollout Management› Priority setting and follow-up on installation progress› End-customer communication (on-site and call center)
Integration of AMR system into Elektrilevi IT landscape› IT architecture solution design and implementation› Responsibility for all integrations and IT developments
SLA level and Meter warranty
Project preparation: timeline2010 March - Project initiation in Elektrilevi2011 July - Procurement documents were released
2012March - Partner selectedAugust - Signing of ContractJune – October - AMR and work order management implementation and integrationNovember - Start rollout of Pilot installation
2013February - Acceptance of PilotMarch - Start of Mass Rollout
2016September – Conclusion of Mass rollout
Technology overviewCommunication Technology› Protocol based on DLMS/COSEM › Power Line Communication: PLAN+› Wireless communication: GPRS/UMTS
Technology highlights› Interoperability (IDIS)› Pushed messaging from Meters to System› Head-end system with standard interfaces (IEC)› Proven and customer tested technology› High level security
PLC Concentrators› 10 500 ~ 44% of all substations

Mass rollout overview› Rollout duration 2013-2016 (Pilot rollout Q4 2012 - Q1 2013) › Rollout execution (during peak times ca 100 installers)› Average daily installation volume – 600 - 800 meters› Expiring meters - 44% of total meters had fixed installation Quarters as
requirement in Legislation (pictures below show rollout happening all over the country at the same time)
› Mass rollout - replacement of meters per full transformer areas

Field installation› Critical prerequisite for field installations is the planning
› What, when and where needs to be installed (example pictures) › Educate the logistics people to ensure smooth deliveries› Maintain sufficient buffer stock of field equipment› Training and tight control on the installers to ensure quality› Notifying end-customers in time is crucial to ensure access to meters
› Lot’s of Estonian meters are installed inside apartments› Central management system is needed for electronically follow-up the
chain from ordering to tracking of installed meters

PROJECT MANAGEMENT
System operationSystem operation covers two key domains:› IT solution administration
› AMR, Work Order Management, › Monitoring, Ticketing...
› Meter and Metering Data management (back-office and field activities)› Missing metering data handling› Faulty device (meters, DC) handling› Metering data analytics (events/alarms, abnormalities in metering
values)› Device configuration management
Communication in ProgramGeneral communication - Elektrilevi› Why meter replacement is needed› How and in which sequence it is done› http://www.elektrilevi.ee/en/kauglugemine
Installation related end-customer communication - Ericsson› Required agreements to access end-customer premises› Clarifications and information sharing during installations› Call centre for general inquiries
Customer satisfaction ratings (on 5 point scale)Regular end-customer meter replacement satisfaction index (Target level is
4,2 – current index level is 4,7)
Core topics Things to be clarified before project start:
› High level – Clear understanding what, why and when must be achieved
› Balancing the expected performance/functionality and TCO
› Technology roadmap - is interoperability and/or mix of different technologies opportunity or problem
› Stakeholders engagement – Customers, regulators, market participants
› Public Opinion – clear strategy for all customer segments
› Emergency rules – be prepared for accidents in all processes and levels
