Budapest, Hungary 15/16 April 2015 IEC TC13 Plenary Meeting Working Group 15 Report John Cowburn - Convenor Budapest, Hungary 15/16 April 2015

IEC TC13 Plenary, Budapest, April 2015 TC13 WG15 - Report Content New Scope of Working Group 15 Progress on activities to achieve new scope Result of voting on the NWIPs The revised plan of work Detail of work planned to meet new market requirements for payment metering systems Detail of work planned to respond to changes in emerging TC13 metrology, safety and communication standards IEC TC13 Plenary, Budapest, April 2015

TC13 WG15 – Scope “Smart Metering Functions and Processes” WG15’s original scope was ‘payment metering’ and development of the IEC 62055 series Many smart metering systems include a payment mode e.g. pay as you go ‘Payment functionality’ may exist in the meter or other devices in the metering system Several architectures can be envisaged, covering multiple “energy types” e.g. gas, water, heat Two NWIPs, a RR and a DC were issued for standards to cover existing and emerging systems IEC TC13 Plenary, Budapest, April 2015

TC13 WG15 – Progress on 2014 work plan Proposals raised for new work items in 62055 series to cater for payment functions in smart metering systems. 62055-41 to be updated to Ed.3 to add new security features. Documents issued: 13/1590/RR & 13/1591/DC (from GB NC) IEC 62055-41 Ed.3 to cover; ZA requirements (Annex A, STS) GB requirements (Annex B, GBCS) IN requirements (Annex C, CTS). 13/1593/NP (from South African NC) IEC 62055-1-0: Framework for standardization of Smart Meter Functions and Processes; 13/1594/NP (from South African NC) IEC 62055-61: Smart Meter Functions; IEC TC13 Plenary, Budapest, April 2015

TC13 WG15 – NWIP Voting Results 13/1591/DC for IEC 62055-41 Ed.3 supported, no objections. Maintenance Team will proceed. See plan of work slide. 13/1593/NP for IEC 62055-1-0 Ed.1: Supported by 21 P-members, 10 abstentions, zero opposition; Experts provided by CN, GB and ZA. Rejected as five required. 13/1594/NP for IEC 62055-61 Ed.1: Both NWIPs have consequently been withdrawn. Agreed that IEC 62055-21 Ed.1 Framework Standard for Payment Meters, to be reconfirmed because the NWIP for IEC 62055-1-0 has been withdrawn. IEC TC13 Plenary, Budapest, April 2015

TC13 WG15 – Revised Plan of Work Three Maintenance Team projects: 62055-31 to be amended then later revised Project Leader: J.Cowburn 62055-41-1 Ed.1 for token carrier systems using STS, with updated security features. Project Leader: D. Taylor 62055-41-2 Ed.1 for markets where STS is not used, using transfer reference numbers (TRN). Project Leader: T. Field IEC TC13 Plenary, Budapest, April 2015

IEC TC13 Plenary, Budapest, April 2015 TC13 WG15 – Revision of 62055-31 Ed.1 Two stage maintenance process planned: 62055-31 Ed.1 Amendment 1, including Corrigendum 1: Safety requirements to be revised to refer to 62052-31 Ed.1; Project Start – April 2015. Expected duration – 3 months. 62055-31 Ed.2 Particular requirements for Payment Meters: Update metrology references to WG11 Ed.2 when CDVs circulated; Update of payment functionality to latest DLMS/COSEM standards, including requirements from STS 101-2; Revision or removal of Load Switch tests in Annex C to align with 62052-31 requirements plus liaisons with TC23 and TC121; Aspects of Multi-Device Payment Metering to be considered, including split meters and group meters; Project Start – When WG11 CDV’s circulate. Duration – 12 months. IEC TC13 Plenary, Budapest, April 2015

IEC TC13 Plenary, Budapest, April 2015 TC13 WG15 – Revision of 62055-41 Ed.2 Revision of IEC 62055-41 to be prepared in two parts to cater for Standard Transfer Systems (STS) and systems using Transfer Reference Numbers (TRN). Part 41-1 to introduce changes from 13/1591/DC Annex A Provide enhanced security of STS systems; Work started. Expected duration – 9 months. Part 41-2 to introduce changes from 13/1591/DC Annex B&C Specify TRN’s from UK-DECC GBCS for GB systems; Specify TRN’s from Indian CTS systems; Work start – May 2015. Expected duration – 18 months. Full document titles IEC 62055-41-1 Ed.1 Electricity metering – Payment systems – Part 41-1: Application layer protocol for one-way token carrier systems – Standard transfer specification (STS). IEC 62055-41-2 Ed.1 Electricity metering – Payment systems – Part 41-2: Application layer protocol for one-way token carrier systems – Transfer reference numbers (TRN). IEC TC13 Plenary, Budapest, April 2015

IEC TC13 Plenary, Budapest, April 2015 TC13 WG15 – Revision of 62055-52 Ed.1 Possible revision of IEC 62055-52.
