IET 4th Annual Smart Metering Conference 8-9 March 2011 Richard Williams 8 March 2011 eSmart-P-014 v1.2I am Richard Williams and I work at Cambridge Consultants, an Engineering Design company. We provide our development services to a wide range of business covering many markets including Consumer products and Industrial sensing which includes Utility meters.With the rollout of smart meters we have been considering why and how the metering and consumer appliance worlds should come together.This is what I will talk about today.

  3. 3. 1. Why Smart Meters must define their communications with the Home Reminder: Why we are rolling out Smart Metering? DECC forecast benefits £17Bn (domestic rollout) { Achieving the EU 2020 climate change Other targets benefits Energy Progressing to the 2050 target of an saving/CO2 80% reduction in greenhouse gas emissions Debt Smart metering will help to achieve this handling through No – Better information and advice for estimated consumers bills – Load shifting and load control – Support for micro generation Load Avoiding – Integrating electric vehicles and home shifting meter reading energy storage with the grid Source: Impact Assessment of a GB-wide Smart meter rollout for the domestic sector, 2010 3 8 March 2011 eSmart-P-014 v1.2First let’s remind ourselves why Smart Meters are being deployed.Smart metering has two main areas of benefitFirst are the Customer Service and Operational benefits of meter reading, billing, payments and efficient change of supplierSecond are reducing energy consumption and shifting the time when energy is used. This will provide the dual benefit of reduced energy cost to the consumer and reduced carbon emissions. These are the two blue segments pointed to on the chart.It is these later benefits which are at risk if we do not have effective communications between Smart meters and home systems.There is a lot of focus on the 2020 climate change targets but it is the 2050 goal of an 80% reduction in greenhouse gases where smart meters must make their main contribution. The smart meters which will be rolled out in the period up to 2020 will have an operational life extending to 2050.Our energy mix in 2050 is still being planned but for domestic housing there will be a substantial shift from gas to electricity. This combined with the introduction of major new energy consuming devices in our homes like heat pumps and electric vehicles makes the need for accessible open communication to the smart metering system even be greater.

  4. 4. 1. Why Smart Meters must define their communications with the Home The UK Smart Metering Programme does not define interfaces for the Consumer Smart Meters should enable consumers to add services and products to make their homes more energy efficient Current scope of the proposed UK system 4 8 March 2011 eSmart-P-014 v1.2Now consider the scope of the Smart Metering System which is being defined for the UK.This diagram should be familiar to those of us involved in the UK programme.The system comprisesIn the home: Electricity and Gas meters, an In-Home Display IHD and WAN comms module (more generically known as a gateway). The responsibility for installing and operating these is with the Energy Supplier.Outside the home is a central WAN communication and data aggregation function which provides the communications between all 26M homes’ Smart meters and the relevant energy supplier. This central comms system will be operated by a new organisation known generically as the DCC or Data Comms Company.The UK programme is focussing on two interfaces in the system.Interface 1 as I term it which is the connection between the gateway and the WAN. This must be defined as the Energy suppliers will be responsible for ensuring the meter’s gateway will communicate with the WAN. There is an added complication with this interface as the DCC will lag the start of the meter rollout and the WAN will be defined after some meters are installed. The proposed solution is to implement the WAN comms as a module in the home which can be upgraded.Interface 2 as I term it is also known as the Meter HAN. There will not be universal supply and ownership of the meters in a home by one energy supplier. Many homes get gas from one provider and electricity from another. Consequently an interface must be defined so that meters, IHD and gateways from different suppliers will work together.What is missing from the UK Programme, and is needed, is a third interface between the smart metering system and the consumer’s appliances. Page 4
  5. 5. 1. Why Smart Meters must define their communications with the Home IHDs (In Home Displays) do not achieve enough energy saving on their own IHDs are a good start: Universal and simple – But sustained savings <2% Information should be available on many devices – TV, PC, Smartphone …. – And new devices that become available in the next ~20 years With multiple methods of consumer engagement – Analysis, advice and feedback – Peer group comparison – Rewards and encouragement Interfaces should not limit future methods – Or access by the organisations that can provide the services and products 5 8 March 2011 eSmart-P-014 v1.2Why do we need this third interface?Current plans are to include IHDs in the roll-out at no additional cost to the consumer. These devices will provide a relatively simple interface for the consumer which can be located in a convenient place in the home.Many trials with IHD have been carried out to assess their influence on the consumers energy use. These trials have shown a rage of results but the longer term trend shows that an IHD combined with some generic energy saving advice results in an average consumer saving of less than 2%.Everyone would agree a consumer display (or User Interface) is an essential part of a smart home energy system but there should be a wide choice of devices and methods which are available to display the information.The other key consideration is how and what information should be displayed. Different formats will suit different users and the information will range from presenting data, to billing/payment, receiving specific advice, and interacting with peer groups, friends etc - the social networking phenomenon.Looking to the future the most important consideration is supporting new means of interacting with systems. Who can tell what devices we will have in our pockets in 20 years time?The Smart Metering system needs an interface which will evolve to support the new products that become available. Page 5
  6. 6. 1. Why Smart Meters must define their communications with the Home Appliances must interface to the Smart Metering System There are two mechanisms to shift the time when energy is consumed – Time of Use (ToU) pricing and Load Control Appliances must have electronic access to this control data – ToU pricing in 30 min intervals and load control <5sec response The future will require more complex interaction and control – Integration of local generation and storage – Energy budgeting – Consumption profiling and optimisation 6 8 March 2011 eSmart-P-014 v1.2The other main requirement is that appliances must interface to the Smart Metering System. I use the term appliances not only to mean washing machines and other white goods but any energy consuming or energy controlling device in the home.Varying the price of energy with time and direct control of devices to turn them on and off are the two main mechanisms that are proposed to encourage consumers to time shift when they use energy.Appliances must be connected electronically to the smart meter system for these mechanisms to work.Today many appliances could have the communications and simple control functionality to work with these load shifting mechanisms. For exampleA clothes washer could be set to run overnight with a requirement to complete by 7.00am - It then chooses the cheapest time to run from the Time of Use tarriff data in the Smart metering system.Fridges and freezers, particularly those with good insulation, can easily have their power off for 20-30 minutes and still keep cool.Looking a little into the future and considering more complex systems where homes will have a combination of micro generation, storage and imported energy then the need and complexity of communication with the smart metering system becomes even greater.As an example a typical domestic space and water heating system could comprise a combination of solar thermal heat panels on the roof, an electric heat pump and a thermal store. With this arrangement the controller needs to combine: Future electricity tariffs, and weather predictions for both anticipated solar output and space heating requirements. Should I charge the thermal store tonight with low cost electricity powering the heat pump or will the Solar Panels generate enough heat tomorrow?Developing this concept further, what are the benefits in homes being able to predict their energy requirements?Perhaps they could “Negotiate” with the energy supplier for the best rateOr they could inform the grid of their energy requirement for the next few days and also the times when this energy will be needed. This information can then be used by the Grid Operators for planning and load management.All this requires communications with the smart metering system. Page 6
  7. 7. 1. Why Smart Meters must define their communications with the Home The interfaces must be defined now The UK specifications will be frozen this summer with roll-out starting mid 2012 – Equipment suppliers are developing now with their best estimate of the UK spec. The UK specifications must include the interface definitions when they are frozen – The cost of home visits to upgrade hardware soon exceeds the cost of 100% installation at roll-out – The inconvenience of a further home visit will put off consumers from using this feature. – The interface can be enabled and updated after installation using firmware upgrades. Source: UK Smart Metering Programme Prospectus Launch July 2010 7 8 March 2011 eSmart-P-014 v1.2Timing is important and for the UK the interfaces must be defined now.The smart meter roll out is a step change and a big bang process. The system will be defined, built and deployed with very little opportunity for evolution in this process. It will then be in place for 15, 20, 30 years or more.There will be little or no opportunity to revisit the system design in a few years time.Consequently the external interfaces must be defined before the roll-out and when the rest of the technical specifications are confirmed later this summer.With the installation of the Smart Metering System the cost of upgrading after roll-out is very high. Even if a feature is only used in a percentage of installations, it is cheaper to do a 100% fit at roll-out rather than go back and upgrade the meter in a subsequent home visit when the feature is requested by the customer.Incidentally this is one of the main reasons all gas meters will include a valve so they are prepayment ready.

  8. 8. 1. Why Smart Meters must define their communications with the Home Why do we need to define an open standard – Why not let industry and the free market evolve a solution ? Consumers will face a barrier to switching energy supplier because the Smart Energy services and products they use are not interoperable Smart Energy service and product suppliers will adopt different standards and solutions – e.g. Measurement devices or network standards Consumer’s investment will be limited by a lack of product interoperability The diversity of solutions will create uncertainty for the consumer 8 8 March 2011 eSmart-P-014 v1.2Why do we need to define a standard. Suppliers are already offering solutions with the type of functionality I have been describing and these will develop and evolve as the smart meters are rolled out.The answer is:This will work to a point but there will be a number of barriers to uptake which would be removed not if the interfaces were standard and open.Energy suppliers will provide Smart Energy services and products. These may not be compatible between suppliers requiring consumers to change all or part of their Smart Energy system when they switch their supplier.Alternative consumer owned measurement devices will be introduced because the readings from the Smart Meters are not readily available. This will result in differences between the consumer’s system’s measurement of consumption and calculation of cost and the Energy Supplier’s billing. Typically consumer owned measurement devices are clip on current monitors for electricity and hence only estimate Voltage to calculate the energy consumed.Gas is difficult to measure without an expensive and professionally installed meter so many consumer Smart Energy systems will not cover this. At the moment Gas accounts for typically 3-4 times more domestic energy consumption than electricity so it should not be ignored.Finally the market for Smart Energy systems will be limited and develop more slowly. Rather that offering the benefits of choice the differing and incompatible systems will make consumers unwilling to make purchases and for the same basic reasons manufacturers will be unwilling to invest in the market.

  9. 9. 1. Why Smart Meters must define their communications with the Home How to make this new Smart Energy market attractive to appliance companies? Appliance companies will ask: Which interface should my product have to access the Smart Meters ? Governments are wary of imposing standards What information will be available from – Not their role and anti-competitive the Smart Meters ? But the opposite is true Is it a level playing field? – an open and appropriate standard will – Can I maintain and enhance the value create a market and enable competition of my product ? There are many successes: – How can I be compatible with other – Telecommunications: Media storage: products ? Computing: The Internet Is the market large and predictable ? This will be the case for Smart Energy Defined interfaces are essential for positive answers to these questions ! 9 8 March 2011 eSmart-P-014 v1.2This leads on to my next point: How do we make this new market attractive to appliance companies.Organisations which are considering entering the smart energy market will be looking for a market which is large, predictable and accessible (i.e. has few barriers to entry). They will want to compete and differentiate on the basis of how they can help consumers reduce their energy bills and carbon emissions not on how they can access data which already exists.This is particularly true of appliance companies who are already operating in a mature market and need to produce standard products in large quantities to be competitive.Supporting 3-4 different physical communications networks and applications interfaces for each country is not viable.Having standard defined and open interfaces provides the certainty that products will be interoperable and facilitate investment and development on the key objectives of energy saving.As an aside one of the reasons that standard interfaces are not being defined is governments are reluctant to do this. They see it as stifling competition and not their place to interfere with the market. However the opposite is also true. Where there are no defined open standards the uncertainty prevents the market developing.The important thing is to understand the particular details of each market and get the balance between sufficient definition to create competition and an attractive market and not too much which will prevent competition. In the case of Smart Energy defined standards will help competition. Page 9
  10. 10. Agenda: 1 Why Smart Meters must define their communications with the home 2 What are the candidate system architectures 3 What technologies and standards fit best 4 Conclusion 10 8 March 2011 eSmart-P-014 v1.2In the past few slides I have discussed why Smart Meters must have a defined interface. Now I will go on to look, at a fairly high level, at an architecture which includes a suitable interface with the Consumer’s Smart Energy Systems. Page 10
  11. 11. 2. What are the candidate system architectures Two interfaces are key 1) The Internet It is the preferred choice for many consumers – Can be accessed outside the home (almost anywhere) – Can be accessed by many existing consumer devices – An established, familiar and mature channel It is the preferred choice for many Smart Energy suppliers – Services are held and upgraded centrally – Future proof: – Long life and is continually being developed – Existing solution for security and other key services – An Open system with many technology providers Use of the Internet for Smart Energy is inevitable. This must be standardised 11 8 March 2011 eSmart-P-014 v1.2Two interfaces are key. The first is the internetThe internet is already the preferred choice for many consumer to business interactions.It is inevitable that it will be a key interface by which consumers and the businesses, proving smart energy products and services, will access the data from the Smart Metering system.The internet is an open system, supports secure transactions and is constantly being developed to meet new requirements. It is future proof.Standardisation of the interface to the Internet is required to provide a defined application interface through which consumers can access the same data in the same way whoever their energy supplier is.Access to the interface would be controlled by the consumer to ensure data privacy and consumer’s ownership of their data. Consumers can then chose and give permission to the third party organisations who they wish to give access to.This could be an organisation offering energy saving services or a social networking site with energy saving peer groups.The important point is it is the consumer who decides who can access their data and can easily grant and withdraw permissions. Page 11
  12. 12. 2. What are the candidate system architectures Two interfaces are key 2) The Consumer’s HAN in the home For the consumer Appliances access data directly – It is universally available (does not from the Smart Meters require the internet) No Broadband router is required – Simple: Appliances connect directly to the Smart Metering System – Do not need to trust the internet with personal data Energy Consumer’s Supplier For the Smart Energy Supplier Smart Smart Head-End – Low latency and good Quality of Energy Metering DCC Appliances Service (helps Load Control) Cluster (Data Comms – Reduces data traffic on the Co) WAN (data can be held locally in Consumer Metering the meters) HAN HAN 12 8 March 2011 eSmart-P-014 v1.2The second key interface is between the smart meters and appliances in the home. This interface has already been considered in some national Smart metering systems. For example the Netherlands with the NTA specifications and Germany with the OMS.This interface offers a number of important advantages over the Internet. It will be available in all homes that have smart meters and will allow simple system solutions where appliances can connect to the meter system without any additional hardware or services.A consumer can buy a Smart washing machine from a retailer as normal; install it and it can start working with the ToU tariffs from the Smart metering system without the need for the consumer to have their own router or ay other “infrastructure devices”. All network management and routing functionality would be available in the interface to the smart metering system within the home.This simple solution will make the Smart Energy accessible to all consumer not just those with access to the Internet.From the energy supplier perspective this interface offers the advantages of low latency and deterministic communications between the smart metering system and appliances. This is important for load control. Page 12
  13. 13. 2. What are the candidate system architectures The Meter HAN and Consumer HAN should be separate Device and network ownership are aligned – Consumer devices on the Consumer HAN and Smart Metering devices on the Meter HAN The high reliability and security of the Smart Metering system is not compromised The Meter HAN is unlikely to be compatible with consumer devices Technical evolution of the HANs is decoupled – Consumer products and technology have a shorter lifetime than Meters The consumer is only aware of their HAN – There is concern that two networks will confuse the Consumer 13 8 March 2011 eSmart-P-014 v1.2Looking in further detail at the connection between appliances and the smart meters the Meter HAN which connects the meters, IHD and WAN module or gateway should be separate from the HAN which connects appliances and other devices in the home.Compared to directly connecting appliances to the HAN this has many advantages:First: Device and network ownership are aligned. With metering devices on the Meter HAN and consumer devices on the Consumer HAN problems of incompatibility and operating failures are not spit between two owners. Neither the consumer or energy supplier would welcome the prospect of sorting out why a new appliance a consumer has just bought and installed will not connect the Meter HAN or worse still has broken it preventing the meter system from operating.Second: The needs of each HAN can be better served by the relevant technical solution. The meter HAN needs high reliability, restricted access, good security and low power. The consumer’s HAN can benefit from being compatible with other consumer devices in the home.Third: The consumer HAN can evolve as new technical solutions and standards are introduced. The Meter HAN will need to remain unchanged for the lifetime of at least one set of meters and maybe longer -30+ years. It is almost in conceivable that consumer networks will not change significantly in this time frame.Finally there is a concern raised in the UK prospectus that there should only be single HAN to avoid confusing consumers. With separate networks this is not problem because the Consumer is only aware of a single network. The Consumer HAN which they own and use. Page 13
  14. 14. 2. What are the candidate system architectures Recommended Architecture Interface 3 – Proposed additional interface The third Interface defines how the Smart Metering System communicates with Consumer devices via the Internet and via the Smart Meter’s in the home Interface to the Internet Internet Interface 3 Interface 1 { DCC WAN Energy HOME (from DCC to Smart Metering Cluster 26M Homes) Energy Supplier Firewall Broadband Energy Supplier Router + Gateway HEC Interface to the Supplier HEC Command Consr HAN Smart Metring Consumer’s HAN HEC Web Server Access Firewall Response Network Control Point Command Consumer’s Coordinator HAN Response Interface 1 IHD IHD Interface 2 Is the communications PC TV from the Smart meters DCC in the home to the Consumpt’n E Meter Electricity (Data Comms Co) Meter DCC.

This is called the Discharge Boiler Water ? Meters HAN interface 14 8 March 2011 eSmart-P-014 v1.2This diagram shows the overall proposed architecture. It is quite detailed and so I will highlight a few areas.1) The defined Interfaces between The Smart Metering System and Consumer HAN are shown as Interface 3 highlighted in red.2) Firewalls are shown at both the Internet and Smart Metering Cluster connections. In this architecture both connections would operate a typical client server style interface with the consumer’s Smart energy system pulling data from the Smart Metering System. This arrangement provides an explicit and secure mechanism to protect the Metering system from being disrupted by interference from the consumer’s system.3) Micro generation from renewable sources (mainly wind and solar) is a key part on many countries energy strategies and these are supported by Feed-in-Tariffs FITs. Consumers are paid both for the energy they generate locally and for any excess they export to the grid.Generation meters are owned by the consumer but they provide data which is used for billing by the energy supplier. So which HAN should they be on Consumer or Meter?In the proposed architecture the location should follow ownership. Where the generation meter is owned by the consumer it is located on the Consumer HAN with a push mechanism to transfer readings to the energy supplier.If the energy supplier provides the generation meter it would be connected to the Meter HAN.It is this type of architecture which puts Consumer Smart Energy appliances at its centre that the UK program should be defining and not the diagram I showed earlier.

  15. 15. Agenda: 1 Why Smart Meters must define their communications with the home 2 What are the candidate system architectures 3 What technologies and standards fit best 4 Conclusion 15 8 March 2011 eSmart-P-014 v1.2The final part of this presentation will briefly show that existing technical standards used for consumer networks can also be used to provide the connections to the Smart Metering System. Page 15
  16. 16. 3. What technologies and standards fit best IP can provide the communications protocol solution for both the Internet and Consumer HAN interfaces to the Smart Metering System Client Server architecture fits Consumer interaction with the Smart Metering System It has well developed services for key areas like Security and Firewalls to protect the differently owned parts of the system Consumer appliances only need to support one protocol – It can be used for both the Internet and Consumer HAN interfaces Future proof – Operates over different physical layers – No obsolescence: Evolves to address new requirements and problems – Consistent with the long term trend and intension for Smart Metering 16 8 March 2011 eSmart-P-014 v1.2As shown on the proposed architecture the client server arrangement fits Consumer interaction with the Smart Metering System.The Internet Protocol is well established and suitable for both the Internet connection and the connection between the Meter HAN and Consumer HAN in the home.This has the advantage that consumer appliances are simplified as they only need to support one protocol. The same appliance can be used with either connection and, if the data application layer is also standard, then the appliance does not even need to know which connection is being used.IP is also consistent with the longer term trends for Smart Metering which is looking to adopt IP particularly for the Grid. To support this move to IP networking standards like ZigBee are developing 6LoWPAN. Page 16
  17. 17. 3. What technologies and standards fit best WiFi is a good choice for the interface to the Consumer’s HAN There are several candidates for this interface: ZigBee, WiFi, Z-Wave are examples. – A full analysis is required to define the best choice – The imperative is to define a single standard which will create the largest market pull for suppliers to invest in Smart Energy products and services Why not use WiFi ? – The most widely adopted Wireless LAN in homes with an increasing number of devices connected by WiFi. – In particular PCs, TVs and Smartphones all of which could be display and control devices for a home energy system. – The mature technology and large market has driven down the cost of WiFi components – WiFi has good support for web services and the Internet 17 8 March 2011 eSmart-P-014 v1.2Now we turn to the physical interface in the home.Home network standards for Automation and Smart Energy have been developed against the requirements of low cost, low power and low data rate. A diversity of standards, combined with no dominant reason to chose one over the other, has resulted in a limited uptake of these standards.In contrast WiFi has achieved a large penetration as the preferred Wireless LAN standard at home, work and in public spaces.An increasing number of products are including this interface driven by the convergence of computing and media handling devices. PCs, TVs and Smartphones all of which should be used for Smart Energy display and control have WiFi.WiFi is mature and the large market and multiple suppliers have driven down the component costs. There are many technology and software suppliers and widespread development engineering expertise is available. Page 17
  18. 18. 3. What technologies and standards fit best WiFi is adaptable to the Smart Metering System interface requirements No dedicated router is needed – For homes without a router WiFi supports router functionality to create a local Hotspot Too high power: WiFi is the backbone network – Ultra Low Power systems such as lighting or heating control are connected as subsystems to the WiFi network For set-up and authentication key entry – Use the IHD or existing WiFi devices like a Smartphone Range and node density limitations are addressed with repeaters – More than any other standard in the unlicensed band WiFi has already proven itself at high densities 18 8 March 2011 eSmart-P-014 v1.2Although it is sometimes included in reviews of suitable HAN technologies for Smart Energy, WiFi is not top of the list. Power consumption and cost have been two reasons to discount WiFi.In reality the incremental cost of adding WiFi is similar to other wireless LANs and the level of silicon integration has already reached the point where WiFi can be included as a sub-system on a complicated SoC (System on Chip). With WiFi so prevalent, the overall cost of an alternative solution would be higher because the alternative interface would be added to devices which already contain WiFi.Considering power consumption in the proposed architecture, where Meter and Consumer HANs are separate, the low power requirement for the Consumer HAN is not essential. (The low Power Meter HAN requirement is driven by the battery powered Gas (and water) meters).Where very low power solutions are required in the home, e.g. for a lighting or heating control where nodes are battery powered, then these would be connected as subsystems on their own low power networkwith WiFi providing the main backbone.More recent developments in WiFi have included “Hotspots” where WiFi nodes have the ability to provide router functionality and create a local network. This facility would be included in the gateway interface to the Meter HAN to enable Smart Appliances with WiFi to operate directly with the metering system in homes where there is no internet interface or separate WiFi router. This is the simple solution I described earlier.WiFi is a good choice for the consumer HAN and if adopted would provide a huge acceleration in the consumer’s engagement with Smart Energy. Page 18

  20. 20. 4. Conclusion Action now to define interfaces to the Internet and Consumer’s HAN will transform the value of Smart Meter Installations Smart Meters must communicate directly with appliances and other consumer devices to Internet achieve the required reductions in energy consumption and carbon emission Investment requires stability, certainty, an Consumer’s Smart open market and a long term opportunity Energy Meters – A Smart Metering System with defined Systems interfaces will provide this for Consumers and Appliance companies to invest in Smart Energy Systems Existing solutions based on WiFi and the Internet can provide suitable defined interfaces for the Consumer The UK national Smart Metering Programme has the opportunity to create an environment which will both boost the economy and create a world lead 20 8 March 2011 eSmart-P-014 v1.2To summarise.Smart Metering Systems must include communication interfaces to Consumer appliances so that the Smart Energy Systems necessary to reduced energy consumption and carbon emissions can be created.These interfaces must be defined and open to create an attractive accessible and competitive market for Smart Energy products and services.Existing technical solutions including the Internet and WiFi can be used for these interfaces further increasing the accessibility and uptake of Smart Energy.The UK national Smart Metering programme has the opportunity to create an environment which will boost the economy and create a world lead. It must act now to include the definition of interfaces to the Consumers Smart Energy System.Thank you! Page 20
