    Concepts and theory sounds great, but upon closer inspection:

    A. Utility bills are increasing where smart meters are installed, not decreasing.

    B. Customer information from smart meters is NOT formatted for customers and does NOT change customer behavior towards conservation.

    C. The cost - benefit of smart meters is horrendous and is being promoted to profit the utility companies and their suppliers, not customers or our society or our environment.

    D. The Smart Grid does NOT use or require a smart meter on each home. The necessary smart information can be gathered much more efficiently and timely and inexpensively at energy distribution points. (The smart grid does not care or need to know how much power any one home uses.)

    E. The vast amount of unnecessary and nearly useless information to be handled and stored may actually raise energy usage.

    F. This massive Billions-of-dollars smart meter program will leave NO funds for programs that would truly bring energy saving solutions and the public will not be receptive to real solutions after being burned by these Smart meters.

  5. 5. IntroductionW elcome to Smart Metering For Dummies, your guide to the exciting new world of smart meter-ing and the impact that it’s likely to have on the utilitiesmarket and beyond.About This BookThe words ‘exciting’ and ‘metering’ rarely make it intothe same sentence – but all that’s about to change. Smartmetering is not only set to revolutionise the meteringservices sector, it’s also the catalyst for the singlebiggest wave of change to hit the utilities industrysince the introduction of retail competition. This bookexplains the why, how, and when of smart metering andits effects on customers, suppliers, and distributors.To keep things simple, we use the term ‘smart’ to referto smart meters and ‘conventional’ to refer to existingmeters.Foolish AssumptionsIn writing this book, we’ve made some assumptionsabout you. We assume that: You work in the utilities sector and understand the basics of how the electricity and gas markets work. You want to know more about smart metering and how it will affect suppliers, distributors, and customers.
  6. 6. 2 You understand some of the utilities and metering jargon (we include a glossary at the back of the book, just in case).How This Book is OrganisedSmart Metering For Dummies is divided into six conciseand informative sections: Part I: Get Smart. We discuss the business driv- ers behind the move from conventional to smart metering and the benefits to be realised by the key stakeholders. Part II: What is a ‘Smart’ Meter? We explain what makes a meter smart and how it differs from its conventional cousin. Part III: The Anatomy of an Advanced Metering Infrastructure. We describe the key components of the infrastructure required to support smart metering and attempt to demystify some of the associated smart jargon. Part IV: Feeling the Impact of Smart Metering. In this section we take a look at how the key stake- holders will be affected by the smart revolution. Part V: Looking to the Future. Smart metering won’t happen overnight. In this part we examine some of the long-term parallel activities that will influence, or be influenced by, a smart metering rollout. Part VI: Top Ten Smart Tips. This nifty part is a list of the essential things to remember about smart metering.

  8. 8. Part I Get SmartIn This Part Exploring the move towards smart metering Discovering the benefits for the customer, supplier and distributorC ollectively, individuals are responsible for over 40 per cent of the UK’s energy use and carbondioxide (CO2) emissions. Back in February 2008, theGovernment estimated that over £900 million waswasted every year by simply leaving domestic appli-ances on standby when not in use! To address this,everyone needs to become more energy savvy. Withsoaring fuel prices and more and more families fallinginto fuel poverty, the motivation for a change in behav-iour is growing. What’s missing is the informationrequired to make smarter decisions.This part looks at the drivers for introducing smartmetering and examines the benefits for some of the keystakeholders.
  9. 9. 5Driving towards Smart MeteringSmart metering provides: Customers with the information they require to become energy savvy and make smarter decisions about their energy usage. Suppliers with the means to better understand and service their customers. Distributors with an effective tool to better moni- tor and manage their networks. In addition, smart metering enables those cus- tomers who choose to generate their own electricity (microgenerators) to be financially rewarded for their contribution to the national grid and distributors to better manage this contribution.What’s in it for the customer?Individuals need to understand their energy consump-tion in order to make intelligent decisions about it.Currently, customers are informed of their energy usevia a bill that arrives months after they’ve used the gasor electricity. The bill typically only tells the customerthe cumulative consumption since the last bill and,more often than not, even this is estimated. It isn’t sur-prising that customers don’t feel empowered tomanage their energy use.But providing individuals with the timely, accurate, anddetailed information they require to take control oftheir energy use is only one of the benefits that smartmetering can bring. Other benefits include:
  10. 10. 6 Estimated bills will become a thing of the past. Customers will know what they owe and will be able to budget better. New, innovative tariffs will appear, tailored to meet the needs of specific customers’ lifestyles. Customers will get better service such as on- demand readings (for example, on changing sup- plier or moving home). Smart meters will measure electricity generated from domestic microgeneration, enabling house- holders to be financially rewarded for their contribution.What’s in it for the supplier?For the energy supplier, smart metering will enable thetransformation from an energy supply company to anenergy services company. Smart metering will allow asupplier to get closer to its customers, to better under-stand and service their needs, and, at the same time,allow the supplier to reduce its operating costs: The cost to service customers will reduce with increased customer self-service. Suppliers will have fewer bill queries, complaints, and site visits. Call centre staff will become more productive. Meter reading costs will reduce dramatically as meters are read remotely. Suppliers will be able to differentiate themselves through an extended range of products and serv- ices offered into the home.
  11. 11. 7 Energy theft will be reduced through smart tamper alarms. Improved visibility and control of customers’ con- sumption behaviour will enable suppliers to better balance their wholesale positions.Smart metering also presents a new battleground forretail competition where the customer-savvy and inno-vative supplier will triumph.What’s in it for the distributor?UK distributors have been just a little bit late to jointhe party when it comes to smart metering comparedto their European colleagues, where the key driver isto enable the smart grid (check out Part VI).However, here are some of the benefits that smartmetering will bring to distributors: Smart metering will provide distributors with the ability to more accurately bill suppliers for use of the distribution networks in delivering electricity to their customers. Functionality within smart meters will enable system faults to be notified and located more quickly following power cuts and interruptions. Smart metering will give distributors better visibil- ity of their networks, enabling more cost-effective maintenance regimes. More detailed consumption data will enable dis- tributors to measure, rather than model, network losses, reducing the need for reconciliations and providing greater revenue certainty.
  12. 12. 8 As with suppliers, distributors will benefit from reduced theft and fraud through smarter tamper alerts and better monitoring of non-technical losses.Who else stands to benefit?Everyone stands to benefit from smart metering: The increased use of remotely managed Time of Use (ToU) and block tariffs (see Part II) will help spread the UK’s energy consumption more evenly across the day, easing the stress on our distribu- tion networks and reducing the need for costly generating plant to meet the peak demand. An overall reduction in energy consumption insti- gated by an energy-savvy public will reduce the impending gap between forecast demand and gen- eration and help restore security of supply. Less consumption means less CO2 emissions and less climate change.
  13. 13. Part II What is a Smart Meter?In This Part Discovering what makes a meter smart Unearthing the smart impostorsW hat exactly is a smart meter and why is it clev- erer than the little box currently stuck on thewall? This part looks at what makes a meter smart andhow it differs from its conventional predecessors.Smarter than YourAverage Meter ...So what makes a meter smart? Traditionally, meters situnder your stairs or in the garage and are only dis-turbed when the meter reader comes to take a reading.Well, at first sight, smart meters don’t look a whole lotdifferent as you can see in Figure 2-1. Like their conven-tional cousins, they still sit in infrequently visited loca-tions, but now they’re not even disturbed by meterreaders.
  14. 14. 10Figure 2-1: These meters look similar but are a world apart.Surprisingly, there’s no absolute definition of what asmart meter is and this lack of a standard is one of theobstacles to a wide-scale UK smart metering rollout(which we talk about in Part IV).However, this section delves into the widely-acceptedcharacteristics of a smart meter.Two-way communicationIn addition to being remotely read, smart meters canbe remotely instructed and re-configured. Actionswhich, in the case of conventional meters, necessitatelengthy site visits and meter changes, can now be per-formed remotely in near-real time.Actions that can be remotely performed with a smartmeter include:
  15. 15. 11On-demand meter readings. Reading a meter innear-real time in response to a customer phoningthe call centre, for example.Change of tariff. Changing tariff rates and tariffstructures in response to a supplier-instigatedprice change or a customer electing to move to anew, innovative smart tariff, for example.Change of payment method. Switching betweencredit and pre-payment modes.Change in read frequency. Changing the con-sumption read interval from, say, monthly to daily,or even half-hourly.Load limiting/shedding. Remotely controlling anagreed portion of a customer’s consumption inorder to help balance generation and demand or asa means for preventing customers from running upmassive debts while still having access to energy.Tamper alerts. Automatically detecting, notifying,and responding to attempts to tamper with themeter.Disablement/enablement. Turning supply on andoff in response to, say, a tamper alert.Messaging. Communicating directly with the cus-tomer via the smart meter and Home Display Unit(HDU – described in Part III).Firmware updates. Remotely updating the soft-ware embedded within the smart meter in orderto fix bugs or add new functionality.
  16. 16. 12Detailed consumptionSmart meters are capable of recording consumptionin far more detail than their less sophisticated, con-ventional cousins. Meter readers typically visit everyquarter but not always when you’re at home! So thelevel of consumption information available to cus-tomers and suppliers is pitiful. Suppliers have no meansfor encouraging people to change consumption behav-iour and customers have no means of knowing whattheir consumption behaviour is! Smart meters can record very detailed Time of Use (ToU) consumption down to half hourly and beyond. ToU refers to a meter’s ability to record when consumption takes place rather than just how much is consumed. Customers can see how their consumption varies during the day and respond to new ToU-based lifestyle tariffs that encourage them to use cheaper energy. Changes in behaviour can have the effect of flattening consumption peaks which, in turn, reduce the need for expensive, carbon-polluting peaking plant and network reinforcement.Not just electricitySmart meters exist for commodities such as gas andwater as well as electricity. Given that electricity doesn’tmix well with either gas or water, gas and water smartmeters tend to be battery-powered. Battery technologyis constantly improving but, to avoid the costs of sitevisits to replace batteries, these meters tend to spend alot of the time asleep, waking up according to a scheduleto take and transmit readings.
  17. 17. 13 Time to find out about Time of Use (ToU) A meter that can record ToU is called a ‘restricted’ meter and records consumption by having different registers active at different times. For example, a restricted two-rate meter may have one register that records consumption overnight and another that does so during the day. This enables the supplier to apply different tariff rates that reflect the differential between the wholesale cost of day-time and night-time electricity.Smart electricity meters, on the other hand, have readyaccess to a power supply and are therefore frequentlyused as the means of communicating data from gas andwater smart meters. The gas and water smart meters‘piggy-back’, by communicating via low-power radio tothe electricity smart meter, which stores and forwardsthe data as additional registers within its own meter.Export as well as importWhereas conventional domestic meters only recordconsumption, most smart meters are also capable ofrecording electricity generated from domestic micro-generation plants and exported to the distribution grid(solar panels, for example). The ability to measure theoutput from microgeneration means that customerscan be fairly rewarded for their contributions, whichmakes smart meters one of the key enablers for thewidespread adoption of microgeneration.
  18. 18. 14Not quite smart enough ...The following technologies often arise in smart meterconversation but shouldn’t be confused with the realthing. Automatic Meter Reading (AMR). An AMR meter can be read remotely but reading the meter is the only remote function supported. The benefits of AMR metering are restricted to reducing meter reading costs to the supplier and the ability to bill the customer based on actual meter readings. Clip-on electricity monitors. These little devices are sensors that clip onto the cables feeding con- ventional electricity meters and wirelessly trans- mit near-real time consumption information to a portable display unit located elsewhere in the house. The display unit shows how much electric- ity is being consumed and how much CO2 this represents. However, clip-on electricity monitors have signifi- cant limitations when compared to smart meters. There’s no equivalent clip-on monitor for gas or water meters, no remote supplier access (so none of the supplier or distributor benefits of smart metering can be realised), and no improvement in billing because the supplier still has to manually read the meter.
  19. 19. Part III The Anatomy of an Advanced Metering InfrastructureIn This Part Thinking about what’s needed to support smart metering Communicating with a smart meterS mart meters require different bits and pieces to support them and this part describes the majorcomponents required.Introducing the AdvancedMetering InfrastructureMost smart metering solutions will have the same basicstructure as illustrated in Figure 3-1. This structureis generally referred to as the Advanced MeteringInfrastructure (AMI).
  20. 20. 16 Smart Meter Home Smart Wide Area Area Network Meter Network Internet (HDU) (HAN) (WAN) Data Portal (MDM) System Data CollectionCustomer Home Display Unit Smart Stakeholders (’Head-End’) System Meter Meter Data Management (Customer, Supplier, Distributor)Figure 3-1: The AMI components.
  21. 21. 17Home Display Units (HDUs)Home Display Units (HDUs; sometimes referred to asIn-Home Display Units) are the devices that you put onyour wall or fridge to inform you about your energyconsumption. Communicating wirelessly with thesmart meter (either directly or via the Home AreaNetwork which we explain in the following section), theHDU displays near-real time information on energyusage, cost and greenhouse gas generation for both gasand electricity. A common feature is a coloured lightindicator to tell you when to run around switchingthings off!It’s fair to say that HDUs have a way to go to becomingthe must-have stylish home accessory but it’s only amatter of time . . .Home Area Networks (HANs)The Home Area Network enables devices and appli-ances to communicate with each other. The obviousexample is the smart meter and the HDU. However,appliance manufacturers are becoming more and moresavvy to the idea of home networking. The vision of a‘smart home’, in which appliances, lighting, heatingand security are connected and automatically con-trolled to save energy and improve occupant well-being, isn’t far around the corner.Wide Area Networks (WANs)What makes a meter smart is its ability to hold a two-way conversation with a data communication (or‘head-end’) system. The medium over which thiscommunication occurs is called the Wide AreaNetwork (WAN).
  22. 22. 18 Although, in principle, smart meters could have their own dedicated WAN, a number of communication infrastructures are already in place that are capable of fulfilling the WAN role. These include the copper and fibre net- works of fixed line telephony providers, the cellular networks of the mobile phone opera- tors, and the power lines of the electricity dis- tribution networks.Data Communication systemThe data communication, or ‘head-end’, system isresponsible for pulling together data from a large anddisparate set of smart meters. It handles two-waycommunication, sending service requests to the meterand receiving messages such as scheduled meter read-ings. In order to communicate with a smart meter, ahead-end system must ‘speak’ that meter’s protocol.Unfortunately, there’s currently no smart meter equiva-lent of Esperanto, so head-end systems need to be multi-lingual. Alternatively, a smart metering solution can usemultiple head-end systems or stick with one meter man-ufacturer to standardise on a single protocol.Meter Data Management(MDM) systemsSmart meters can produce a prodigious amount of datacompared to their conventional cousins, which typi-cally only record non-interval data (meaning only when-ever someone manually reads it, usually once everythree months). Smart meters, however, are capable ofrecording interval consumption, meaning that they auto-matically record consumption at a pre-defined interval,
  23. 23. 19typically every 30 minutes (in the UK). So a smartmeter can produce over 4,000 times as much data ayear as its conventional counterpart.An MDM system is a single repository capable of stor-ing the vast quantities of meter readings and other dataassociated with smart meters. It typically gathers datafrom one or more head-end systems.Data portalGathering vast quantities of metering data is all verywell but has little benefit unless that data can be trans-formed into valuable information and made available tothose who will act on it. A data portal is the means bywhich the data collected in the MDM system is madeavailable to whoever needs it – the customer, supplier,or distributor. Some MDM products also include dataportal functionality.How Do I Talk toa Smart Meter?When industry types start talking about smart meters,the conversation inevitably turns to communicationtechnologies. So here’s a quick primer so that you canhold your own at the coffee machine.You can communicate with a smart meter in anumber of ways, each with its own advantages anddisadvantages: Power Line Carrier (PLC): Also known as Power Line Communication, PLC technology carries data across the same power line that’s used to deliver electricity. Meters talk to a smaller number of con- centrators (communication devices) across the
  24. 24. 20 power lines. The concentrators then talk to the central head-end system via a communication technology such as GPRS (explained in a moment). The major advantage of PLC is that it’s effectively free. Disadvantages are the need for concentra- tors and the fact that, due to power lines being inherently noisy environments, communications often need to be repeated, leading to slower response times. Broadband over Power Line (BPL): Also known as Power Line Internet, BPL is the use of PLC tech- nology to provide broadband through ordinary power lines. Using BPL, a smart meter can enjoy a virtually free, always-on connection to the central head-end system. However, as with PLC, BPL requires concentrators and is subject to line noise which often requires a large number of repeaters to boost the signal. General Packet Radio Service (GPRS): GPRS is a packet-orientated mobile data service that can be used to provide an always-on wireless connection between a smart meter and a central head-end system. GPRS uses a mobile operator’s WAN and requires the smart meter to be fitted with a pro- prietary SIM card. Unlike BPL, the connection isn’t free but is typically charged per megabyte of data moved. However, it can cope with large volumes of data (for example, when updating a smart meter’s firmware). Short Message Service (SMS): Also known as text messaging, SMS involves sending fixed size text messages via a mobile operator’s WAN using a SIM card installed within the smart meter. SMS is
  25. 25. 21typically cheaper than GPRS and can have abroader coverage. However, SMS is less suitedto the transfer of large data volumes.Radio: Radio waves can be used to communicatewith smart meters either locally (low power radio)or long range (licensed or private frequency). Bothrequire additional infrastructure (for example, con-centrators and/or dedicated radio masts).Wi-Fi: Wi-Fi is the trade name for a popular wire-less technology that enables a device to make awireless connection to the Internet via an accesspoint (or hot spot). The advantage of Wi-Fi is thatit’s relatively cheap to Wi-Fi-enable a smart meter.The disadvantage is the limited coverage of hotspots due to the fairly high power requirements.ZigBee: ZigBee is a low-cost, low-power wirelessmesh networking standard. Like Wi-Fi, communica-tion via ZigBee is cheap. However, it’s best suitedfor local coverage such as Home Area Networks(HANs).
  26. 26. Part IV Feeling the Impact of Smart MeteringIn This Part Looking at the effect of smart metering on cus- tomers, suppliers and distributors Sharing success storiesS mart metering will have a profound effect on cus- tomers and the utilities that service them. Here,we consider some of these impacts through referenceto real-life examples.Impact on CustomersSo, what impact will a smart meter have on your aver-age customer?Better informedA key objective of smart metering is to make customersmore energy savvy. The timely provision of detailedconsumption information will empower customers tomake smarter choices about how and when they useenergy. Given the continued upward trend in world
  27. 27. 23energy prices, this empowerment is bound to appeal tocustomers and increase their expectations of the serv-ice they receive from their energy suppliers.Better billedA welcome customer benefit of smart metering is thedemise of the estimated bill. Infrequent meter readingsand poor access rates mean that many customers arebilled on estimated, rather than actual, consumption.This can result in customers unknowingly running upsignificant debts and exacerbating the problem of fuelpoverty. Energy savvy Swedes The 22,000 inhabitants of Växjö, a city in Sweden, are now more energy savvy thanks to an energy-efficient urban devel- opment project sponsored by the European Union (EU). Householders are now able to analyse their energy usage via a web-based system developed by Logica. The purpose of the system is to increase customers’ energy awareness by making analysis simple and informative. The system includes a com- petitive element, enabling householders to compare con- sumption with peers and compete for prizes based on reductions in their energy consumption. Ann-Mari Ståhlberg, President of Växjö Energi AB, said: ‘With this solution, we’re able to offer our customers something we always aim for, namely, the opportunity to influence and increase the efficiency of electricity consumption.’
  28. 28. 24 Getting the bills right Swedish legislation demands that by 1 July 2009, all electric- ity meters must be read once every month. Energy company Vattenfall’s solution to this challenge was to deploy smart meters to its customers and, with Logica as a key partner pro- viding the Advanced Metering Infrastructure, has now installed over 150,000 smart meters. Hundreds of thousands of meters reporting daily creates very high volumes of data. Despite these volumes, the system has exceeded its reliability targets, consistently running at levels well above 99.5 per cent of collected values in a 24-hour period. As a result, Vattenfall experiences higher levels of sat- isfaction among its customers and fewer calls querying bills, because the bills are based on up-to-date information. Furthermore, the system provides information about power outages and power return for each customer, creating a valu- able quality control resource. Erik Nordgren, Head of AMR Project Vattenfall Eldistribution AN Sweden said: ‘There’s no question that automated meter- ing has helped us deliver better customer service.’With smart meters, readings are available on-demand.Smart meters are typically read more frequently than acustomer is billed. However, on-demand meter readingscan also be taken in-line with a customer’s billing cycleor a price change to ensure that every bill is based onactual consumption. With smart meters, the only excuse for billing on estimated consumption is a faulty meter.
  29. 29. 25Better servicedSmart metering provides suppliers with the tools nec-essary to better service their customers. With improvedvisibility of a customer’s consumption behaviour, sup-pliers are able to deliver innovative service offerings,tailored to the needs of individual customer types. It’sno longer a case of ‘one size fits all’. Bringing prepayment metering into the 21st century Mention ‘prepayment’ to most energy retailers and they go pale. Prepayment meters are typically installed for customers who’ve had debt problems in the past. Unlike credit meters, prepayment meters require the customer to pay up front before consuming energy and can also be used to recover out- standing debts over a period of time. As such, prepayment customers are often perceived to be high cost, low value, and labour intensive - why would you want that type of customer? Instant Energy, an innovative application of mobile technology to the prepayment market, has transformed prepayment cus- tomers into a profitable and desirable market segment. Developed by Logica, Instant Energy is designed to replace existing prepayment metering technology, leading to reduced costs in serving prepayment customers, improved customer experience, and reduced fraud. The solution is an electricity and gas prepayment service based on SMS messaging and the Pay As You Go (PAYG) concept. The technology enables customers to add credit to their prepayment meter without (continued)
  30. 30. 26 needing smartcards, keys, or tokens - and without necessitat- ing the customer to leave their home. Instant Energy won the British Computing Society 2005 IT Professional Award for Social Contribution in recognition of the increased flexibility and control it grants customers.With smart metering, existing service offerings such ascall handling, are improved. Call centre staff are able tocommunicate with the meter while the customer ison the phone and see the same information that thecustomer sees. This leads to faster calls and a higherproportion of first-time call resolution.Impact on SuppliersThe impact of smart metering on suppliers will be mas-sive. It will not only change the way suppliers view andengage with their customers, but it will also open a newbattleground for retail competition.Smarter processesIn 1998, customers could choose who they bought theirenergy from for the first time. While this new-foundfreedom passed many people by, the impact on suppli-ers was profound. Retail competition required a wholenew set of industry processes, data flows, and IT sys-tems. The change to the industry was monumental and,a decade later, many suppliers are still catching theirbreath.
  31. 31. 27The advent of smart metering represents the nextmajor disruptive transformation to the retail market.Processes that previously took days or weeks tocomplete and involved many people from differentorganisations can now happen in near-real time via aself-service customer web portal. The potential forchange is breath-taking and, many would argue, longoverdue.Smarter competitionSmart metering will create a new battleground for retailcompetition.A new supplier must be able to service their acquiredcustomer without having to replace the customer’ssmart meter. If not, smart meters will represent aninsurmountable barrier to retail competition. So theneed to preserve retail competition is likely to force theadoption of interoperability standards and provide alevel playing field in which all suppliers have access tothe same basic smart meter functionality. The vastly increased detail of consumption data available from smart metering will enable suppliers to understand their customers’ behaviour far better. They’ll be able to distin- guish the ‘early birds’ from the ‘night hawks’, the students from the OAPs, and the couch potatoes from the socialites, just from their energy use. Having segmented their customer base as never before, successful suppliers will be those that can rapidly develop new innovative products tailored to specific types of customers.
  32. 32. 28 A smarter way to change your tariff As an example of the scale of process transformation likely to come about through smart metering, consider the humble tariff change. Today, changing your tariff almost certainly involves changing your meter. You call your supplier who calls the meter operator to make an appointment for the meter change and calls you back to confirm the appointment date. After going round this circle a few times, the meter operator turns up to change the meter and, if you’re lucky enough to be in, you get a shiny new meter. The meter operator then informs every- one and his dog about your new meter and, if the gods are smiling, you start receiving bills based on your new tariff. This process takes days, if not weeks, to complete, involves at least half a dozen parties, dozens of data flows, and is highly prone to errors. In the new world of smart, you could complete this process yourself, online, in minutes.Innovative product offerings are likely to combine anumber of elements such as: ToU tariffs. Block tariffs that have varying rates depending on the level of demand over a defined period. Working capital tariffs that have different rates depending on the level of credit or debt between the supplier and the customer. Given that every supplier is likely to have access to the same basic smart metering func- tionality, differentiation will be done in the
  33. 33. 29 back office and will depend on a supplier’s ability to assemble modular smart meter and back office functions into a coherent, innova- tive product offering. However, a level playing field means innovations can be copied so suc- cess will hinge on speed to market.Coping with the transitionA smart metering rollout won’t happen overnight. Eventhe most optimistic, aggressive rollout models will takea decade or more. During that time, suppliers will befaced with the prospect of supporting two distinct setsof processes – conventional and smart – and the asso-ciated IT that goes with them.Although the number of smart meters will initially besmall, a complete set of new, smart processes and sup-porting IT will be required from day one to servicethem. In the case of the conventional processes, it maywell be a case of letting them wither on the vine.Alternatively, suppliers may look for ‘sunset’ optionsfrom niche providers willing to take on processing ofconventional customers until such times as theysmarten up.Impact on DistributorsIn common with suppliers, a significant proportion ofprocesses currently performed by distributors will beimpacted by smart metering.Smarter processesEarly notification of network faults via ‘last gasp’ smartmetering functionality (that is, the ability of a meter tosend an alert on battery power following a power cut),
  34. 34. 30should enable network faults to be located and resolvedmore quickly. However, this functionality may have anadverse effect on a distributor’s Customer Minutes Lost(CML) performance (an industry measure of the scaleof electricity outages) because the clock will start run-ning at the time of the fault rather than the time thatthe fault is first reported by a member of the public.Smart meters may also improve the resolution of inter-ruptions by providing the ability to communicate withindividual meters to determine their state. Similarly,the ability to read meters on-demand will help toresolve erroneous customer calls (where a house fusehas blown, for example).A distributor’s role in identifying and stopping energytheft is likely to be significantly improved through thereceipt of unsolicited tamper alerts from smart meters.Similarly, more detailed consumption data will ulti-mately enable distributors to measure energy lostduring distribution rather than estimating losses usingcomplex models. A more accurate understanding oflosses will lead to more accurate bills, reduced recon-ciliation wash-ups, and greater revenue certainty.Smarter billingAs with suppliers, distributors will have the ability tooffer more innovative Distribution Use of System(DUoS) tariffs based on the greater detail of consump-tion data available from a smart meter. An increase indistributed energy may force a major re-think of theway in which distributors charge suppliers for use oftheir networks. DUoS tariffs are typically related to theamount of energy consumed by customers. However,an increase in microgeneration and heat technologiesmeans customers will import less energy, resulting in
  35. 35. 31lower revenues for the distributors. However, invest-ment in new systems to control the two-way flow ofenergy is likely to increase the cost of maintaining a dis-tribution network. So distributors’ current cost recov-ery mechanisms are likely to require a major rethink.The smart gridA smart grid is a transformed electricity transmissionand distribution network that uses robust two-way com-munications, advanced sensors, and distributed com-puters to improve the efficiency, reliability, and safety ofpower delivery and use. A UK smart grid is probablyfurther off the radar than in most other European coun-tries, but the drivers for a smart grid (such as the likelyincrease in microgeneration, the need to manage activenetworks, and so on) are the same. Energy networks need to become intelligent. Additional remote monitoring across the net- work will be required to feed data into predic- tive modelling that will enable distributors to actively manage two-way electricity flows (that is, electricity flowing both to and from a household) across the network. Two-way energy flows mean that isolating parts of the network for maintenance will become more complicated. New safety procedures will be required to ensure that field staff are pro- tected from electrocution.Smart metering will be an essential component of thesmart grid, delivering the detailed load and flow infor-mation required to enable distributors to manage thenetwork effectively and support investment decisions.How quickly this becomes a reality in the UK is anothermatter . . .
  36. 36. 32 Smart Europeans In 2005, the SmartGrids European Technology Platform for Electricity Networks of the Future was formed. SmartGrids (as it’s known to its friends) aims to provide a shared vision for a European electricity network for 2020 and beyond. The SmartGrid must be flexible, accessible, reliable, and sustain- able while remaining responsive to the rapidly evolving needs of its customers. SmartGrid’s goal is to change the mindset of the industry into adopting new technologies, addressing real concerns over security and reliability and embracing the SmartGrid vision. SmartGrids is backed by the work of IRED (Integration of Renewable Energies and Distributed Generation), a cluster of European projects with €35 million of EU funding and over 100 stakeholders from research, industry, and the utilities sector.Impact on OthersThe impact of smart metering will extend beyond cus-tomers, suppliers, and distributors. Here are a fewother parties who are likely to feel the effects of thetransformation: Meter manufacturers will need to produce the tens of millions of meters required to smarten up the conventional metering infrastructure. However, suppliers will need to agree on a mini- mal level of smart meter functionality before the production lines can begin in earnest. Meter operator numbers will double or treble to achieve a ten-year UK smart metering rollout.
  37. 37. 33Dual-fuel sites will require either a new breed ofmulti-skilled meter operator or close co-operationbetween existing gas and electricity meteroperators.Data collection will become a virtual activity asincreasing numbers of smart meters are readremotely.Data processors will need to respond to the chal-lenge of smart meters and the associated increasein data volumes.Water utilities with a 100 per cent metering policy(either due to water scarcity, leakage, or both)have the opportunity of piggy-backing on a gas/electricity smart meter rollout to accelerate theirmetering programmes and/or deliver them atreduced cost.
  38. 38. Part V Looking to the FutureIn This Part Delving deeper into microgeneration Living in a smart homeS mart meters aren’t going to magically appear overnight. Even the most aggressive rollouts willtake years, if not decades, and the world at the end of asmart metering rollout will be very different from thatat its start. In this part, we look at some of the parallelactivities that will influence, or be influenced by, awidespread rollout of smart metering.Creating a Buzz in Your OwnBackyard: MicrogenerationThe introduction of microgeneration (households pro-ducing electricity from, for example, solar panels) willfundamentally change the relationship between cus-tomer and supplier. No longer a one-way transaction ofthe customer paying the supplier for delivered energy;the customer will also sell to the supplier and take onthe role of a trading partner.
  39. 39. 35Microgeneration has a huge potential to minimise trans-mission and distribution losses and offset some of theimpending energy gap threatened by the plannedretirement of 50 per cent of the UK’s current generationcapacity by 2020.For microgeneration to flourish, it needs improvementsin technology, a system of financial reward, and, notleast, a means of measuring the power generated. Significant growth in microgeneration will present challenges to distribution network operators who will now need to manage active networks (those in which electricity can flow to and from a customer). Distributed generation will meet demand locally but less predictably, increasing the challenge of scheduling the central generation plant effectively by the system operator. Demand is likely to become more volatile, increasing the challenge faced by suppliers and traders in forecasting wholesale demand.Smart meters, with the capability of measuring exportin addition to consumption, form the key enabler ofthis microgeneration revolution.Home, Smart HomeImagine arriving home from work. As soon as your digi-tal key unlocks the door, your house adjusts the light-ing, heat, and window blinds to your liking and puts onyour favourite music in the kitchen. In your absence,the house has fed the cat, ordered more milk, turnedoff the TV that your kids left on in the morning, andkept electronic vigil over your property.
  40. 40. 36And that’s not all. In response to an updated half-hourlytariff from your energy services company, your househas turned off your freezer and fired up your fuel cellmicrogeneration unit to sell power to the grid.A bit far-fetched? Just think of how homes havechanged in the last five years.For this scenario to become a reality, technology needsto elevate the customer from operator to strategist.The customer takes the strategic decision to adopt asmart tariff and technology takes responsibility fordelivery. In this type of set-up, where you no longerneed to think about when to run the washing machineor dishwasher, half-hourly tariffs become feasible withprofound implications for both wholesale and retailenergy markets. Yet this vision is only conceivable in aworld with smart metering.Smarter SettlementThe energy consumed by a supplier’s retail customersmust be purchased on the wholesale market. Theprocess by which suppliers settle for their wholesalepurchases is likely to experience a transformation trig-gered by smart metering. In the UK, wholesale purchases are settled for every half hour. Half-hourly customers are those that are sufficiently large to warrant their consumption being metered on a half-hourly basis. Non half-hourly customers are those with smaller consumptions that don’t warrant the expense of a half-hourly meter. For these cus- tomers (the majority of people), a system of
  41. 41. 37 profiling is used to turn infrequent meter read- ings into estimates of half-hourly consumption so that it can be settled on the wholesale market. This process is called settlement.As suppliers learn more about their customers throughthe increased detail of consumption data provided bysmart meters, their product offerings will expand asthey identify and target specific types of customer.Some of these products will be designed to encouragebehavioural change through innovative lifestyle tariffs.However, for suppliers to realise the benefits of thechanges in customer behaviour that they’ve broughtabout, these changes need to be recognised in thewholesale settlement.The system of profiling used for non half-hourly settle-ment uses a relatively small set of profiles, changes towhich are lengthy and difficult. This isn’t conducive toa fleet-of-foot supplier looking to differentiate them-selves by rapid deployment of new products.The alternative is for the supplier to move their cus-tomers into the half-hourly settlement process wherethey’ll settle for their customers’ consumption on ahalf-hourly basis. Barriers currently prevent this fromhappening but none are insurmountable.A mass migration of domestic customers to the half-hourly settlement process will see an explosion in datavolumes because annual half-hourly settlement of anunrestricted customer requires over 4,000 times asmuch consumption data as is now the case. While thecentral settlement systems will be insulated from thesevolumes by data aggregation, the settlement agents willbe faced with a profound challenge.
  42. 42. 38Smarter BalancingKeeping the lights on is the job of the system operatorwho must ensure that exactly enough electricity is gen-erated to meet demand on a minute-by-minute basis. Inthe event of unexpected demand or unplanned outagesof generation plant, the system operator invariablyturns to the generators to provide the flexibilityrequired to restore the balance between demand andgeneration. Market mechanisms do exist to allow sup-pliers to contribute to the balancing process but thesehave rarely been used. With the better visibility and control over their customers’ consumption provided by smart metering, suppliers will, for the first time, have the tools necessary to actively par- ticipate in the balancing process and realise the financial benefits this offers. This won’t happen overnight. Nor will it apply to a sup- plier’s entire customer base, but there are customers out there with predictable, inter- ruptible loads who could be helping the system operator to keep the lights on.
  43. 43. Part VI Top Ten Smart TipsT his part is small but packs a punch! Here are our top tips for surviving and thriving in the smartworld.Firstly, some general pearls of wisdom: Think of smart metering as an opportunity, not a threat. Smart metering is coming and the suc- cessful companies will be those that embrace the technology. Think about the process, not the meter. To date, a lot of attention has been focused on the box on the wall but it’s time to start thinking about how to transform your business to exploit the opportu- nities that smart metering will enable. Remember that rollout must be watertight. The rollout of smart metering offers a unique opportu- nity to address long-standing, acknowledged data quality issues in the energy sector – but only if we get the rollout right! Smart won’t happen overnight, so be prepared for the long haul. Even the most aggressive roll- out models are likely to take a decade or more – be prepared to continue to support your conven- tional processes alongside your smart processes or, alternatively, look for sunset options.
  44. 44. 40 Learn from others. Look to countries that are further down the smart road, like Italy, the US, and the Nordic countries, and learn from their experiences.Here are our tips for the energy suppliers: Use smart meters to get closer to your customers. Smart metering offers a unique opportunity to better understand your customers’ energy needs – so use it! Be prepared to be different. The successful smart supplier will be the one that can rapidly translate customer insight into innovative product offerings. Make sure your IT systems are ready for the challenge! Differentiate in the back office, not the meter. Innovations within the meter belong to everyone because everyone is likely to have access to the same basic smart metering functionality. Innovations within your back office are yours alone. Get ready for data – and lots of it. Better cus- tomer insight comes from more detailed consump- tion data. Ensure you have the systems to handle vastly more data than you do today. Remember that customers are people too! The transition from conventional to smart meters will be exciting and disruptive, not least for the cus- tomer. Make sure you have adequate information and support in place to help them through the transition.

  51. 51. The ChallengeThe town of Växjö, in Sweden, was chosen as one of threesites for an EU-funded trial of smart metering and reportingtechnology.Swedish energy company, Växjö Energi AB (VEAB), worked withLogica to develop and implement the trial, equipping 20,000households within the town with a smart meter and develop-ing an innovative reporting system, EnergiKollen.The SolutionEnergiKollen is a web-based solution with easy-to-followgraphics outlining changes in energy consumption. Custom-ers of VEAB can log on to the service over the Internet free ofcharge in order to analyse their usage of electricity, water, andheating. By enabling the comparison of energy consumption(for example, energy use between similar sized apartments),customers are motivated to lower their usage, thus activelycontributing to a reduction in the country’s carbon footprint.The BenefitAnn-Mari Ståhlberg, Chief Executive Officer of VEAB said: ‘VEABis part of many initiatives contributing to a better environ-ment and we are in the forefront when it comes to sustainableenergy development. We have succeeded in reducing carbondioxide emissions from fossil fuels by 86 per cent since 1993,while reducing the total amount of emissions by 30 per centper capita in the town of Växjö. With EnergiKollen we can buildon our achievements and offer our customers what we alwaysstrive for – namely the opportunity to impact and reduceenergy consumption.’
