6 Recent market developments DLMS UA is participant of the EU OPEN Meter project IEC DLMS/COSEM is a core standard in the project IEC DLMS/COSEM selected for the APDRP project Companion specification being developed Companion specification being developed to meet UNI/TS requirements for gas metering IEC DLMS/COSEM, adopted as a Korean standard, will be the basis of a nationwide smart metering project 6

8 Smart metering - open standards EU definition of Open standards (Used in the OPEN meter project) The standard is adopted and will be maintained by a not-for-profit organization (e.g. ISO/IEC, CEN/CENELEC, ITU, ) and its ongoing development occurs on the basis of an open decision-making procedure available to all interested parties (consensus or majority decision etc.). The standard has been published and the standard specification document is available either freely or at a nominal charge. It must be permissible to all to copy, distribute and use it for no fee or at a nominal fee. Quality and level of detail sufficient to permit the development of a variety of competing implementations of interoperable products or services. Standardized interfaces are not hidden, or controlled other than by the standard definition organisation promulgating the standard. The intellectual property - i.e. patents possibly present - of (parts of) the standard is made irrevocably available on a royalty-free basis. There are no constraints on the re-use of the standard IEC / EN DLMS/COSEM meets these criteria 8

9 Smart metering commonalities and differences Common key requirements Multi-energy Messages for the customer Load limitation Connect / disconnect for load & contract management Data security Firmware upgrade Status / Fraud monitoring Country specific environment Market rules and organization Proportion of E, G, H meters Level of consumption Energy prices, labour cost Customer density Supply networks Comm. infrastructures Age of meter park Non-payment, fraud issues All projects are different, hence the need for companion specs 9

10 Int l standards and companion specs Int l standards cover all possible needs, on what agreement is reached general provides choices toolbox Conformance testing tests that what is implemented works correctly Companion specifications project specific reduces options, specifies project specific elements that cannot be specified in IS s Examples: use of identifiers tariff programs contents of load profiles definition of events / status bits Compliance testing verifies that the required elements are present Partnership and co-operation Discipline in using the standards 10

11 Companion specification development Develop use cases Necessary objects available? General interest? Develop specific OBIS code / interface class Develop standard OBIS code / interface class Add to DLMSUA spec Map to objects Add to International standard 11

13 DLMS/COSEM projects Netherlands Project initiated by the government 7 M residential Electricity M Gas meters + small C&I Driven by European Energy Efficiency Directive 2006/32/EC Rollout by Grid operators (GO) 13

14 Dutch smart metering and the DLMS UA NTA 8130: Minimum requirements by Dutch Standards Institute DSMR: use cases, installation and performance requirements Companion specifications by Dutch Grid companies P1 local port: OBIS + IEC P2 port, between meters: DLMS/COSEM - M-BUS P3 port, between meter and CAS: DLMS/COSEM over PLC / GPRS / Eth. New functions: M-Bus client, Firmware upgrade, Load limitation, Disconnect control, Customer information, Events and Alarms handling Advanced data security using cryptographic methods (AES-GCM-128) International standardization P3 Service Module P1 Central Access Server P3.2 DC P3 GPRS, Ethernet P3.1 PLC Electricity meter P0 P2 Gas meter PDA, Laptop 14

15 Dutch approach to standards Standards are needed for interoperability All vendors claim interoperability, yet using different protocols and / or implementations Choice for open standards is evident Choosing a (open) protocol is not enough; to facilitate reaching interoperability a companion specification is required Choosing a vendor specific companion specification may lead to vendor lock-out or biased tenders Utilities and meter vendors have to work together to attain an interoperable solution Meter vendors for technical knowledge and to prevent vendor lock-out Utilities for functional requirements and making final decisions Only labelling as a standard is not enough 15

16 France ERDF project Mandated by the regulator 95% of meters to be replaced by 2016: 35 M meters Objectives facilitate market opening improve efficiency of distribution improve demand management improve customer satisfaction CAPEX: 4,000 M : 800 M / year, during 5 years 30,000 meters to be installed daily largest cost is installation! Return estimated: >10 years 16

17 France ERDF project Pilot project: 300,000 smart meters, 7,000 concentrators Winning consortium leader: ATOS Origin 3 meter suppliers: Actaris, Iskraemeco, Landis+Gyr 3 concentrator suppliers Final objective is to replace all 35 M electricity meters 17

18 French project methodology Formulate criteria for data model and protocols Select data model / protocol / media result: DLMS/COSEM over PLC (S-FSK >> OFDM) Issue tender for trials select one consortium, including at least 3 meter and 3 concentrator vendors, to prove interchangeability specification details being worked out by consortium Full scale rollout 18

21 OPEN meter Work packages DLMS UA contributes to Work packages

22 The Italian Gas metering project UNI/TS series specifies general requirements for gas metering It also specifies two local protocols: CTE and CTE A companion standard is required now to DLMS/COSEM Specific challenges due to battery operation and GSM/GPRS communication The process of specifying the companion standard fosters common approach to the tasks 22

23 DLMS/COSEM new elements for smart metering Multi-metering: M-Bus setup objects Contract / load management: Limiter & Disconnector objects Firmware upgrade Image transfer objects Customer info, Event handling new OBIS codes Data security new version of Association class, security setup PCL media new setup objects, SN block transfer, compact array 23

24 Summary Interoperability in DLMS/COSEM well defined, open standards standard mechanism for extensions common approach to tasks via co-operation self-description: object list, data types, service list, contexts CTT and certification additional application tests may be necessary 24
