4. Summary of Standardization Activities in SDOs and Fora Editor Note: It may be helpful to introduce the structure of the discussiosn below, which have this logic:

• Table of organisations which have a significant amount they could contribute to this document

• List of other organisations, with not so significant impact or no impact, kept as editor note until finalizing this document

End Editor Note

Editor Note: this table is under discussion and will remain as a note for now.

Home Networking

Device Efficiency

Meter Protocols

ATIS ATIS documents are confidential to ESIF, NIPP, OPTXS, PRQC, PTSC, TMOC, WTSC, and NRSC committee members only, so it can only be noted that there is a lot of work on Home Networking and Energy Efficiency.

X ?

ATTM ATTM is an ETSI TC covering energy efficiency topics from the view of minimizing the power usage of various network nodes, and establishing standards for measuring key performance indicatiors, however the scope is in nearly every case outside the Customer Premisies Network.

It has established liaisons with a number of other key SDOs concerning energy efficiency. The associated STF362 has created a series of TS documents. The background information and references in ETSI ATTM TS105174-5-1 are for example relevant to this document. Some of the strategies in ETSI ATTM TS105174-5-2 for reducing power usage in the enterprise can be adapted to CPNs.

BBF

CENELEC TC 294

CENELEC TC 294 covers protocols for remote reading of meters and is very relevant for Smart Metering.

CENELEC TC13

CENELEC TC13 deals with methods of ensuring accurate measurement of power consuption. That is not likely to be considered within WG5.

X

CENELEC SmartHouse

CENELEC SmartHouse programme contains a very large amount of material relevant to WG5 home networks and partly also to Smart Metering, most of it confidential to CENELEC (however see CWA 50487:2005) .

ETSI PLT ETSI PLT is mainly concerned with the PHY and MAC layers of powerline technology, which are not part of WG5 work. But PLT is working on use cases for smart metering.

X

HGI A HGI confidential document is in preparation (HGI-RWD009-R3 HG Requirements for Energy Efficiency) which is very relevant to WI05028. All discussions and documents from the WG for ENERGY are probably relevant. Further information was obtained by liaison.

Synopsis: ETSI EE work on Data Centres is out of scope for WG5. 37

Synopsis: ETSI TISPAN WG5 is currently editor of WI05028 for Energy Monitoring, which corresponds to the work towards Mandate 441. 69

Synopsis: From the abstract, the EE document DES/EE-00015 considers only access network equipment and is out of scope for CPNs. 40

Synopsis: IPCC standards help provide consistent measurement and accounting techniques for end-to-end and “cradle to grave” CO2 production for products and processes. This is useful in administrating for higher efficiency, but offers no mechanisms to achieve it. Out of scope for WG5. 27

Synopsis: ISO has a large number of specifications for measuring performance and processes, including CO2 emissions and energy consumption, however it does not seem (?) to write the specifications for the technical details of the actual measurements. Therefore all (?) of its work is out of scope for WG5. 88

Synopsis: OASIS work on data models could be very valuable for unifying energy monitoring, however specifications are not yet (?) available. 113

Synopsis: The ETSI EE document TS102706 on energy measurment applies to cellular wireless base stations and is out of scope for WG5. 39

Synopsis: The IPSO Alliance does have some “smart home” activitiy, but it is only visible to members. The chair should contact them informally to enquire about the scope of the activities. 134

Synopsis: The June 2009 meeting of the Global Standards Collaboration included over a hundred delegates from the ten largest national or global standardization organizations. Nearly every organization reported on recent strong(er) activity for home networks and/or for energy monitoring and smart-metering. It was clear that a large amount of effort, with relatively little coordination, is taking place. 70

Synopsis: The last documents of the JC were in June 2009, however it shold be considered an important cross-connect of SGs inside ITU. 74

Synopsis: The public documents from ISACC do not indicate any material additional to others already listed in this report, so no liaison is necessary 64

Synopsis: The public documents from ISACC do not indicate any material additional to others already listed in this report, so no liaison is necessary. 64

Synopsis: TIA documents are almost all for members-only, so it can only be noted that they have many activities in Home Networking and Energy Efficiency listed on their website. 79

Synopsis: TTA Korea digital home work items, and energy efficiency topics, are relevant to WG5 WI05028 however none of the website material is in English. Therefore the best collaboration method would probably be face-to-face meetings at convenient conferences, e.g. like the GSC.88

6.1 Introduction The objectives of this WI05028 is defined in the scope:

Proposed work on the different methods of energy control and energy management, i.e., on protocols that control and/or monitor the Energy Efficiency / power modes of devices in the Customer Premises Network. This includes discussion of white-goods, as well as STB, CNG, IPTV, media-storage devices, WLAN Access Points, etc. It is expected that the protocols will allow remote access by users and/or the NGN service provider. Existing work from other fora will be considered, e.g. from HGI, ETSI EE, ETSI ATTM, and from EC Code of Conduct, etc.

ETSI

Draft ETSI SR 0XX XXX V<0.0.4> (2010-04) 17

These objectives are consistent with the European Commission Mandate 441, so that WI05028 can be developed as part of the TISPAN response to M/441.

The Objective of Mandate 441 [Ref?] is creation of European standards that will enable interoperability of utility meters (water, gas, electricity, heat), which can then improve the means by which customers’ awareness of actual consumption can be raised in order to allow timely adaptation to their demands (i.e. ‘SMARTMETERING’) and is in two parts:

• The development of hardware and software open standard(s) for remote reading of meters that

a) support secure bi-directional communication

b) allows advanced information and management and control systems for consumers and service suppliers

• The development of harmonized standards for additional smart metering functionality in an interoperable framework

ESOs are requested to develop a European standard that allows advanced information and management and control systems for consumers and service suppliers comprising, with :

• a software and hardware open architecture for utility meters

• supports secure bidirectional communication upstream and downstream through standardised interfaces and data exchange formats

The architecture must:

• be scalable to support from the simplest to the most complex applications

• consider current relevant communication media and be adaptable for future communication media.

• allow the secure interfacing for data exchanges with the protected metrological block.

The scope of this document is the study of using NGN networks to monitor and optionally control energy consumption in the customer premises, however this is only a piece of a much larger problem space relating to Energy Efficiency, Smart Grid, Machine-to-Machine technologies and even RFID-technologies and Internet-of-Things. Ideally, a solution designed for Smart Metering could be a subset of a solution for M2M.

For example, the figure below shows how SmartMeters in principle are a part of the feedback system of a complete Smart Grid energy generation and distribution and smart-consumption systems which includes also electric-vehicles as storage devices and as devices which may connect to a home network.

The network connectivity needed between the Smart Meters and the Meter-Data-Management, shown above as a “cloud” shape in the figure, is exactly the area where TISPAN and WG5 need to consider standardisation issues. Different transport protocols can be considered optimal, depending on the connectivity bandwidth, latency and reliability.

6.2 Usage Cases

6.2.1 Roles of Participating Entities

The potential participating entities in a system to monitor and control energy usage in customer premises are shown in the figure below: the energy providers, the fixed or mobile network OPERATORS, third-party SERVICE PROVIDERS, micro-power ENERGY FACILITY owners, END USERS such as home or enterprise customers.

6.2.2 Goals

Each of the particpating entities in the system may have multiple goals:

• Operators

o To allow end users and 3rd parties energy management.

o To enable possible future proof of good energy management. This might become an interesting usage case if government directives become stronger for minimising energy usage and CO2 production.

o To enable all the usage cases below.

o Scaleability of communications should be achieved, for example by

� requiring that measurements be aggregated at some point(s) in the data network where individual details are no longer relevant e.g. often this means only a household energy consumption is reported, and not per device or per room

� requiring the frequency or the timing of measurements to be configurable, depending on the devices involved and the services contracted

• Energy Providers

o To allow utility companies to monitor usage in real-time and at low cost, for billing and load prediction.

o To allow utility companies to control the largest power-load sources in the mass markets, so as to balance overall load, allowing savings of excess capacity.

ETSI

Draft ETSI SR 0XX XXX V<0.0.4> (2010-04) 19

o To allow utility companies to get additional revenue e.g. from selling “power management” as a service to end-customers (this of course reduces the revenue from actually selling power, but presumably the case above outweighs this).

• Third party Service providers

o To offer individual users a mechanism to minimize their power usage (for the environment or to save costs) /Note that this mechanism could be by 3rd party, like Google/

• End users

o To be power-efficient is an important secondary decision factor when consumers are buying CE equipment.

o To allow more convenient or energy-efficient scheduling.

o Remote access of the usage cases above.

o Robust local monitoring/control, for example in the case of loss of external communication, or to minimize signalling, may be advantageous in some use cases.

Editor’s note:

Need to add here Energy Facility as one of the participants in the usage case. Such small producers of energy may be at the home, consuming own output or selling to the energy provider, or may be a small “solar farm” The goals of such a participant needs to be checked.

END of Editor’s Note.

6.2.3 Communication Methods

The above goals may be realized using many possible combinations of methods of communications, whereby some examples are given in the figure below. It should be noted that the figure does not try to show location of any “intelligence”: e.g. smart policy systems in home networks, IMS Presence and Context applications in the NGN, database mining in the energy provider systems, etc. However such “intelligence” is required for an efficient system.

6.2.4 Simple Recommendations

It can be seen that, when limited to the viewpoint of Customer Premises Networks, these goals and methods reduce to some simple recommendations. It would be highly desirable if the following could be achieved:

• Smart Meter (which can be connected to a customer premises network) capable of sending and receiving data to the energy provider (or an agent of the energy provider, or a 3rd party)

- Being online for months or years without interruption, makes hardware durability extremely important

• Electricity consuming devices which _may_ be externally controlled over a customer premises network

• Allow management of energy usage, either by home automation systems (including downloadable policies) or by (authorised) external agents. This may include use of IMS features.

• Customer-premises network

- contains the electricity meter and some control/ display interface for users

- should support use of one or more home automation protocols

- should contain a customer-premises network gateway (CNG) or other gateway, to provide a communication link to the energy provider (possibly indirectly through a network operator or a 3rd party), using either NGN or other signalling, using secure bidirectional communication

• The communication link to the WAN should

ETSI

Draft ETSI SR 0XX XXX V<0.0.4> (2010-04) 20

- transmit smart meter information and downlink contol information using standardised interfaces and standardized data exchange formats (to allow interoperability of smart meter systems with different energy provider systems) for all connected meters (electricity, gas, water, heating)

- Allow secure downlink transfer of software updates to reconfigure both hardware and software to some extent, preferably without restart, downtime, loss of data or loss of configuration information.

- Be transparent to securely download through the CNG program updates under control of the core-application service provider.

- Allow secure downlink transfer of tariff changes to appropriate devices

- Be scaleable to support from the simplest to the most complex applications

- be a flexible NGN solution which maintains compatibility with all relevant communication media (e.g. 3GPP, or 4G or DSL, or GPRS etc) and be adaptable for future communication media.

- Editor note: Encryption of the communication between meters and M2M(SM)Gateway (if necessary) as well as between M2M(SM)Gateway and core applications may be a strong requirement, but it needs to be considered how to handle it.

• The solution, including the possible core applications, should:

- allow implementation of “intelligence” (decision algorithms and aggregation of data) at various points in the system

- try to minimize real-time aspects, (Editor Note: “ temporal decoupling of measuring, transport and processing of data, including use of protocol handschakes “ End editor note), especially where it is necessary to improved battery life and/or use less reliable networks

- Provide tight system security for user information, resource allocation, data storage, and memory (for meter and config info) protection.

- Include mechanism(s) in the M2M(SM)Gateway and/or core applications to monitor the whole measurement and control system with respect to operational stability (device or system errors) and also to provide detection of spoofing (ensure data integrity)

- Allow use of backup facilities in the core applications to permit online backups of critical data (meter and configuration and personal/subscriber information) from the M2M(SM)Gateway at regular and frequent intervals. It is desirable that the backed-up version is the definitive data, so as to avoid ambiguity in case of loss of data or connectivity at the customer premises.

- Allow identification of the end-user and the energy provider to eachorher, in a non-repudiable and secure way.

- Allow usage of core applications such as:

� Storage of data and analysing data according to chosen rules (e.g., for predicinng load )

� Creation of a substitute value in case of meter failure or use of temporary or average data, e.g. for load prediction or intermediate billing

6.3 Possible Architectures and Protocols

6.3.1 Architecture

Editor’s note: This section should explore some possible architectures.

One possible architecture for a smart metering system connected to a wide-area communication network, such as the NGN, is shown in the figure below.

ETSI

Draft ETSI SR 0XX XXX V<0.0.4> (2010-04) 21

Figure XX: A possible In-home Architecture for Smart Metering

The architecture according to Fig. 1 enables both automatic remote reading of meters and monitoring/control in a home environment. Devices called M2M(SM)Gateway or M-Bus Room Server collect all the energy data and consumption data measured in a household and transmit it via various possible protocols through the CNG and over the WAN to core applications.

Electricity and gas meters measuring the consumption are connected to the M2M(SM)Gateway via (for example) wired M-Bus (meter bus [1]) installed as a copper pair. Other meters or sensors for e.g. heat cost allocation or Health Care can be connected via wireless M-Bus. For the wireless M-Bus, it might be necessary that secondary M-Bus Room Servers are installed in each room. The room servers can be connected to the main M2M(SM)Gateway via power-line technology (e.g., HomePlug) or Ethernet. In some implementations, the M2M(SM)Gateway may store measured data.

The M2M(SM)Gateway is connected to a CNG. In some implementations the M2M(SM)Gateway might be integrated into a Home Gateway CNG.

The CNG may in some implementations transmit the measured data over a VPN tunnel through the WAN to core-side applications.

Data traffic from multiple M2M(SM)Gateway in different in-home networks might be aggregated according to the reversed client-server model (Fig. 2).

Figure XX: Connection of multiple In-home Architectures to Core applications via the WAN

All measured data stored in all M2M(SM)Gateways, perhaps as XML files containing e.g. timestamp and consumption within the last 15 min) might be transmitted, recorded, and processed by a central client software (core application). A client program in the core application has access to a data repository, which stores all such XML records. An authorized core software application (e.g., OSS, BSS) has access to the repository.

The presence of multiple End Users connecting to the core-side application(s) via the WAN is shown by the blue lines.

6.3.2 Reference Points

Editor’s note: This section should explore some possible common reference points.

6.3.3 Meter Requirements

Editor’s note: This section should explore some possible smart meter characteristics and requirements.

6.3.4 Other Requirements for Sensors

Editor’s note: This section should explore some possible sensor characteristics and requirements.

6.3.5 Home Automation Requirements

Editor’s note: This section should explore some possible home automation characteristics and requirements.

6.3.6 Security, Integrity, Privacy

Editor’s note: This section should explore some security issues.

6.3.6 IMS Issues

Editor’s note: This text is a placeholder for an analysis of various options.

It should be noted that the above descriptions make no assumptions about whether the IMS system within the NGN is used to facillitate some Smart Metering services, or not.The sensors and actuators necessary to Smart Metering and Smart Grid usage cases might in one deployment example be connected “over the top” using an IP-connection (or VPN) directly from the NGN core to the energy provider. In such an example, quite typical of GPRS meter-

ETSI

Draft ETSI SR 0XX XXX V<0.0.4> (2010-04) 23

reading systems in use today, the NGN IMS system is “aware” of the existence of the connection but has no contextual information about the traffic; the operator network is acting as a “dumb pipe”.

In the opposite extreme, the sensore/actuators are provided with identities recognized by the IMS (provision of local idendities is ons of the key functions of the Customer Premises network gateway) and the activity of each sensor or status of an actuator can be part of the contextual “Presence” information for the entity. Such a method would allow all kinds of IMS services to register and use the “Presence” information for example to maintian a complete model of the status of equipment in the customer premises and also couple it to the Presence information for the user (and his mobile device). Remote access to the sensors/actuators is also no additional effort.

End Editor’s note

6.4 Possible Roles for TISPAN TISPAN NGN networks can provide a reliable, secure and authenticated communication link between Customer Premises Networks and external parties, but the exact methods to use so as to provide interoperability between different energy management solutions have not yet been defined. Therefore TISPAN should specify this, with the minimal changes to existing specifications: in the ideal case, only a set of flow diagrams using existing protocols would be needed.

TISPAN should take care that a major advantage of NGN networks - the IMS system for call-control, Presence, Multimedia-Gateways and context-aware applications – is made available to Smart Metering and Energy Monitoring/Control solutions, to help provide the “intelligence” and remote-access which is required by many of the usage cases.

TISPAN CPN networks can provide in-premises networking and security, between Smart Meters and the Customer Network Gateway (which maintains communication towards the NGN and other access networks). TISPAN should note how any existing TISPAN protocols could be used to satisfy smart metering and home automation requirements and if needed describe any additional protocols or reference appropriate specifications from e.g. CEN, CENELEC or other specifications which can be cited within TISPAN.

The integration of smart metering and M2M applications using TISPAN NGN networks requires careful consideration of security and privacy issues. TISPAN should analyse any differences to person-to-person communications, describe how existing specifications fulfill (some of) the requirements, and begin work on any additional specifications or interfaces which may be needed.

The role of TISPAN in all of the above actions is to facilitate use of NGN networks for smart metering and M2M. This requires close interaction with ETSI M2M, 3GPP, CEN/CENELEC and some other industrial fora working in the area.

Annex C: Activities within Industry Fora Editor’s Note: e.g. HGI, BBF, etc

C.1 HGI (Home Gateway Initiative) The Home Gateway Initiative is an open forum launched by Telcos in December 2004 with the aim to release specifications of the home gateway. In addition to Telcos, several manufacturers have joined the alliance. See: http://www.homegateway.org/aboutus/memberslist.html.

HGI has pusblished its main document Home Gateway Technical Requirements: Residential Profile V1.01 in year 2008. It contains the following basic requirements for energy efficiency in Section 8.11 Basic system features:

• The powering requirements aim to lower the power consumption of the HG. This is also the objective of the "EU Code of Conduct on Energy Consumption of Broadband Communication Equipment" [131]. The HGI endorses this Code of Conduct.

• All appropriate Regional/National regulations on electrical safety, EMC, etc, must also be met. • R528. The HG SHOULD support 2 operation modes with different power consumptions: a full operation mode

and a low power mode22. • R529. The HG SHOULD be able to enter the low power mode when the traffic does not exceed a predefined

threshold23 during a selectable period. • R530.Traffic from the WAN or the LAN side exceeding the predefined threshold SHOULD be able to bring the

HG back into full operation mode without affecting user experience. Recommended value for the transition period: 3 sec.

• R531. The HG SHOULD run on DC power, provided by an external power supply module. • R532. The use of a fan is not recommended for reliability and noise reasons. If a fan is used, the noise MUST

NOT exceed 25 dBA. • R533. The HG SHOULD provide Power over Ethernet (according to IEEE802.3af) on its Ethernet (LAN side)

outlets. • R534. The HG SHOULD provide a dying gasp to send a message to the RMS in the case of power failure.

HGI establisched the energy efficiency task force in 2008 described at http://www.homegatewayinitiative.org/aboutus/TF/Energy/Index_Energy.html with chairperson Oliver Lamparter (Swisscom) and Objectives “The ENERGY Efficiency Task Force is developing the requirements that minimise the energy consumption of home gateways. The HGI approach bases the allowable power consumption of the Home Gateway upon the current activity of the HG core and peripheral functions, and minimises service impacts.”

HGI is currently working on the following topics regarding energy efficiency:

• RD009-R3 (Draft document RWD009): Requirements for an energy efficient home gateway. The HGI working

no. is HGI01095.

• RD015-R3 (Draft document RWD015): Energy Efficiency and Ecodesign requirements for a common power

supply (CPS) for home gateway and home networking equipment. The HGI working no. is HGI01219.

• RD017 (No document started yet): Home energy management and control
