Smart Grid Technology conference

I attended the Smart Grid Technology conference in London last week and there were a number of interesting themes which became apparent.

The main theme to emerge was the question of how utilities could engage the residential customer. This is good news – the first step on the road to recovery is acknowledging that you have a problem!

The other two discussion points which came to the fore were 1) that energy is too cheap for small price shifts to incentivise behavioural change and 2) what to do with all the data arising from smart meter roll-outs (the prevailing opinion was that data from smart meters should be used for billing purposes only because that there was far too much data to be of any practical use!). I’ll talk about these in other posts.

The question of how to engage customers is a new one for utilities. Remember, this is an industry that refers to its customers as ‘load points’ or ‘rate payers’! Traditionally, the only time utilities interact with customers is to send a bill, to disconnect, or when the customer calls to enquire why their power is out. Not the most positive of communications, I’m sure you’ll agree! Consequently consumer attitudes to utilities vary from outright distrust to, at the very best, indifference.

How to change this?

Well, any councillor will tell you the best way to fix a relationship is through increased communication. Utilities need to really step up their game when it comes to communicating with their customers. This needs to be done using a combination of updating traditional communications, targeted, viral social media campaigns and good old-fashioned outreach. And this needs to be an ongoing, sustained two-way communication, not once-off and not not one-way.

It is only by building an ongoing conversation with their clients that utilities can build the necessary trust to engage customers in smart grids.

Utilities developing more of a customer focus

by

SAP for Utilities

I attended the SAP for Utilities conference earlier this week in Huntington Beach and I have to say I am impressed by the progress American utility companies are making towards being more customer centric!

The event was titled Sustainability for the New Energy Era and there was a full track dedicated to Smart Grids (obviously I attended almost all of the talks in this stream).

Attendance at the event was surprisingly strong with around 800 delegates despite the current economic woes.

This is the third SAP for Utilities event I have attended and I have to say I was very pleasantly surprised at this event by the number of times customer needs were referenced. Almost all of the Smart Grid talks mentioned the need to involve consumers in the process. Obviously, this is a point I have been banging on about for some time, but it is fantastic to see that the utilities are starting to finally get the message.

One of the best presentations of the event came from Paul Lau of the Sacramento Municipal Utility District (SMUD). SMUD is very unusual amongst utilities in its fanatical focus on its customers – from its About page:

For each of the last eight years, SMUD has received the highest customer satisfaction ratings of any utility in the state in the J.D. Power and Associates survey. SMUD received the second-highest score in the nation for commercial customer satisfaction in 2010.

One reason for this is that Sacramento Municipal Utility District is a community owned electric utility governed by a seven-member elected Board of Directors. SMUD are far from being unique in this model. During Paul’s talk he highlighted other reasons why SMUD is so popular amongst its customers.

SMUD take customer feedback very seriously – in fact, they solicit it. SMUD holds regular focus groups of their customers to find ways they can improve their offerings.

Also, the Board of directors goes out and holds meetings in the community to educate customers about the need for smart grids and consequently they don’t incur any of the blowback which plagued PG&E’s efforts in this area.

Paul commenced his address by paraphrasing Bill Clinton and saying that utilities need to realise that “it is the customer, stupid!” Now, coming from a utility co., that is refreshing!

Lastly, SMUD uses the term customers, not consumers or worse, ratepayers, as many utilities do. Just that slight shift in the lexicon says a lot about how SMUD prioritises its clientbase.

Utilities could learn a lot from SMUD’s focus on the customer – the good thing is that judging from the conversations I had at the SAP for Utilities event, the tide does appear to be turning in that direction.

GE’s U.S. Consumer Impressions of the Smart Grid survey

Results of GE Smart Grid consumer survey

GE published a U.S. Consumer Impressions of the Smart Grid [pdf] survey* recently.

I spoke to the general manager of Metering and Sensing Systems for GE?s Digital Energy business, Luke Clemente about the survey and he told me that the main points of the survey were:

  • 96% of Americans who are familiar with the smart grid are overwhelmingly positive about the technology and what it will do for the country
  • while only 2% thought that smart grid was not a smart investment by utilities and/or consumers
  • 80% of U.S. consumers are excited about upgrading the electrical network with smart grid so that their country can rely more on clean domestic energy sources
  • 78% think that the smart grid would help reduce the number of power outages and restore power more quickly when outages do occur
  • 74% understand that the smart grid will give them the info they need to make better decisions about electricity usage
  • 72% think the smart grid will help them save money on their monthly bills
  • 63% believe the smart grid will create new jobs in the energy sector
  • 66% agree they would buy smart appliances and other in-home devices to maximize their control over energy once smart grid rolls out in their community

In our follow-up conversation Luke said

One of the awareness issues which needs to be driven, is that it does cost more to generate electricity at two o’clock in the afternoon than it does at 2am. To the extent that we can shift our use of energy to less intensive times, that will end up driving better utilisation of the grid and better economics

Luke went on to mention the Department of Energy’s year-long study which showed that consumers, when given information on their electricity consumption, reduced their bills by 10% and reduced peak demand by 15%.

There are three crucial points here –
consumers have quite a positive attitude to Smart Grids
consumers will adjust their behaviour when given information related to their energy use and
that response is good for the grid (and by extension, for its users).

We have seen some instances where utilities failure to communicate effectively with their customers has led to blowback against Smart Meter and Smart Grid projects.

However, as this survey shows, overall consumer sentiment to Smart Grids is positive. Utility companies need to beware that they don’t squander this goodwill – right now it is theirs to lose.

You should follow me on twitter here.

* The survey was conducted in March 2010 by StrategyOne among a census representative sample of 1,000 U.S. consumers via telephone. The margin of error for the sample of U.S. consumers (n=1,000) is + 3.1% at the 95% level of confidence.

What is the best communications protocol for Smart Grids?

by

One of the key tenets of a Smart Grid is that you have real-time, two-way communications between the consumer and the utility company. To enable this a communications infrastructure needs to be rolled out. Before that can happen though, we need to examine the different communications protocols to find the most suitable one.

I was talking to Andy Slater, the EMEA Marketing Director for Sensus, the other day. Sensus are the company providing the communications platform for UK-based Arqiva’s Smart Grid pilot in Reading [PDF]. And their proposed Smart Grid communications infrastructure for all of Britain. While, in North America Sensus have 8 million end points rolled out across 225 utilities.

The Sensus solution uses long range radio to communicate with smart meters. This allows Sensus to achieve a 99.5% first-time connection rate during installations, according to Slater. This is higher than most other technologies (GPRS, WiMax, etc.) and so saves a considerable amount of money by obviating the need for a second call out or re-engineering.

When I mentioned that Power Line Communications (PLC) would, by definition, have as close as possible to 100% first-time connectivity, Andy countered that that’s all well and good for electrical meters but the Sensus solution also works for gas and water meters. He then went on to point out that PLC requires far more repeaters to boost the signal and that it is not suitable for high voltage equipment.

The other advantage which Andy mentioned is that for gas and water meters which are not powered, battery life is going to be an issue. GPRS and mobile solutions require a lot of power and their battery life may be as short as 5 years whereas Andy claimed because the power requirement of long range radio is lower, the batteries in their meters could last up to 15 years, thereby reducing service calls to replace depleted batteries.

Listening to Andy, you could be forgiven for wondering why any utility would go with a communications protocol other than long-range radio – so can anyone enlighten me – what is the best communications protocol for Smart Grids?

Can Arqiva provide the Smart Grid communications infrastructure for Britain?

by

Communications Mast

We had a really interesting Smart Grid related conversation with a company called Arqiva the other day.

I hadn’t heard of Arqiva before but they are quite a significant player in communications infrastructure. They own or have exclusive marketing rights for 16,000 communication masts in UK – what they call vertical real-estate! They also own, operate and maintain all of the UK’s terrestrial television network as a regulated monopoly. And they are responsible for rolling out the switch-over from analog to digital broadcasting for the country.

If that weren’t enough Arqiva are Europe’s largest provider of satellite linkage services!

All very well I hear you say, but what does this have to do with Smart Grids?

Well, Arqiva have a fascinating proposition. They are expecting Ofgem (the regulator for the electricity and gas markets in Great Britain) to announce some kind of central procurement for a Great Britain-wide network and if that occurs, Arqiva would be in a very strong position to bid for it.

They have dedicated UHF spectrum (412 MHz) and a nationwide mast footprint already capable of reaching 100% of the homes in the country. A significant advantage of the dedicated long range spectrum (apart from the lack of contention) is that it will have no problem reaching into houses where meters can be located under stairs or in basements, for example. Cellular networks don’t have the same luxury and are more plagued with health concerns around the transmissions from their masts.

Having a single provider of the communications infrastructure for smart grids is a very appealing proposition – especially if it has regulated returns and contestable pricing which you would expect in a system like this.

Arqiva announced [PDF] just the other day that nPower is joining Arqiva’s Smart Grid proof-of-concept network which covers 80 square kilometres around Reading. nPower are a significant utility with around 6.5 million residential gas and electricity accounts throughout the UK. This will allow Arqiva to test smart gas as well as smart electricity meters and they ultimately want to include smart water meters in their network as well.

Arqiva say they have thought about security as well (which is just as well seeing as a single communications network for electricity, gas and water makes for an extremely attractive strategic target). They are using encrypted communications over licensed spectrum, and are operating a closed system so that should help but security is a constant battle so it is one they will need to stay on top of.

If Arqiva manages to roll this out successfully in the UK, this will leave them in a very strong position to reproduce this model in other countries.

Understanding the Smart Grid – my TreeHugger interview

by

Interview

Photo credit Lee Jordan
Jaymi Heimbuch contacted me recently to ask if I’d agree to be interviewed for a TreeHugger article she was planning to write on Smart Grids. “Love to”, I said.

Jaymi sent on the questions, I replied and today she posted the interview on TreeHugger.

Here are the questions and my answers:

TH: What’s the biggest barrier with smart grids right now? Is it utilities not latching on? Is the technology too new? Is it that not enough people understand what it is?

There are multiple barriers to complete smart grid roll-outs at the moment. The biggest one, as far as I can see is money!

The smart meter roll-out alone costs in the order of $150 per household just for the device. Then there is the installation engineer on top of that. And the software to back it up. In terms of the software, remember that presently utilities take maybe one meter reading a month. When they start taking readings from smart meters they will be taking up to 2880 per 30-day month when they are taking 15 minute readings (or 720 for hourly readings). If they have 1 million customers they go from 1m meter readings a month to 720m per month (or 2,880m). That’s a massive jump in the amount of incoming data which needs to be stored, queried for billing, and held for however long.

A lot of the software to handle this is still being developed and utilities, being very conservative, don’t want to be guinea pigs. And newer technologies tend to have a price premium.

Circling back to the price for the utilities. If they have 1 million customers, they are looking at spending hundreds of millions on the smart grid roll-out (smart meters, communications infrastructure for smart meters, back-end database for data, back-office apps for using the data – customer care, billing, etc.).

One of the big deals about smart grids is that it will help us reduce our consumption – from the utilities perspective, they should invest these large sums of money so we can reduce the amount we purchase from them? You can start to see the difficulties.

TH: What’s the most apparent way a smart grid will change the average person’s daily life? What about the most important way?

You know, the best way a smart grid could change the average person’s life is ‘not a jot’ – apart from reduced utility bills.

Utilities are talking up demand response programs and how they will be able to come into your house or apartment and turn down your air conditioner (for example) at times when supply is short and demand is high. This is a top-down approach destined to piss off customers and will in no way get buy-in from a skeptical public.

Far preferable would be some kind of automated demand response, completely controlled by the consumer, so far example as a homeowner I’d set my dishwasher at 8 PM to come on at 5c per kWh or 5 AM, whichever comes first. As long as the dishes are done by 7 AM, I’m happy. Similarly with other devices. Plenty of loads in the home are movable. You don’t care when your hot water is heated, as long as it is hot when you need it hot. A well lagged (insulated) boiler would mean you could heat it when electricity is cheap, and then use it whenever.

By the way, totally counter-intuitive but cheaper electricity has a higher renewable percentage so actively selecting for cheaper electricity means you are actively selecting for electricity with a higher percentage of renewables in the mix. How does this work?

Well, electricity prices on the wholesale market are very volatile. Consumers are protected from this but electricity prices can fluctuate by orders of magnitude within a 24-hour period. Price is set by good old supply and demand. Demand fluctuates according to day of week, time of day and by season. As the price drops on the wholesale market, it becomes less attractive for more expensive generators (the ones with start-up costs for their generation – the fossil fuel burners, for example) to stay selling in so they drop out. The renewables, on the other hand, are price takers. They don’t have significant start-up costs for generation so they stay in the market no matter what price they get. So, as the price drops, more and more fossil fuel generators drop out and the percentage of renewables in the mix increases!

TH: Other than this change in demand and timing, how will the smart grid help us incorporate renewables into the grid?

Utilities are used to dealing with a situation where their generation (gas coal, oil) is steady and predictable in its output and their customers’ demand is unsteady but generally predictable (demand tomorrow = demand this day last year +1-2%, say).

For various reasons utilities are having to move to a situation where they need to incorporate more renewables into their mix. Renewables generation is not steady and is only slightly predictable (via weather forecasts, for example). Because electricity has to be used as it is generated (can’t be stored, generally), the more unstable the generation, the more unstable the grid.

How can you fix this? Well, one way would be to align the demand with the supply.

How do you do that? Well, as supply and demand shift, they affect price on the wholesale market. So, if you expose people to the real price, they will modify their behaviour to select for when price is lowest (when electricity is in lower demand (or when their is a higher percentage of renewables as I mentioned earlier)). This is demand response.

Now, however you do it, if you roll out a demand response program, you are aligning demand with supply. The more you do that, the more stable you make the grid. The more stable the grid, the more renewables that can be added to it.

TH: Many people in the US are concerned with information privacy – they want to own their energy usage data and don’t want utilities handing it over to governments and third parties. What are some of the steps both businesses and people can take to appease people’s concerns?

Let me tell you, people in the EU are far more sensitive to data privacy issues that in the US! Honestly, on this question, I’m not sure there is a good answer though.

Consider your mobile phone. It is a tracking device. As long as it is on, it knows where you are 24×7 (and tells your mobile provider). Mobile phone records have been used to both exonerate and help convict people in recent years.

Now consider people working in the call center of your mobile phone company. How much are they paid per annum? If I offer to slip one of them $2k do you think I could have access to your movements for the last 6 months? Similarly for your energy consumption data soon.

The best way to protect against this is legislation. Legislate to keep data private and have very heavy fines for the utilities (and mobile phone co.s) for breaches. This will incent them to put processes in place to track inappropriate accesses to people’s data (and disable export functions, etc.).

TH: What’s your favorite saying about the smart grid, or a quote or insight that you always remember?

I spoke to Dr Monika Sturm a couple of years back. Monika is director of Siemens Center of Competency for smart meters – their research and development facility. She told me that the output from smart meters is extremely granular. So much so, that it is possible to look at the output of smart meters and identify all the devices which make up the reading. So by looking at the output from my smart meter, it would be possible to see that I have a 2008 Philips 37″ LCD TV, and a 2006 Indesit BHZ model fridge and a …. You get the idea.

This plays back to the privacy question you asked earlier but it also offers an alternative revenue option for utilities who are looking at people reducing their consumption. It goes something like this:

I get an email from my utility saying

“Dear Tom,
we notice that you have an Indesit BHZ fridge. This is currently costing you ?25 per month to run. We have a newer, more energy efficient model on special this month for ?10 per month. It will cost you roughly ?10 per month to operate so overall you will save ?5 per month if you avail of this offer.

If you sign up, by simply replying to this email, we will have our partner install the fridge by the end of the week and we can take away your old fridge for you, for no extra charge.”

Or similar.

TH: Anything you want TH readers to be sure to know about?

The problems associated with smart meters in places like Bakersfield were entirely predictable. [Editor’s note: Bakersfield residents felt the new smart meters from Pacific Gas & Electric led to inflated energy bills. It resulted in a lawsuit.] Utilities are not used to communicating with their customers. They do so only when it is time to send the monthly bill. With the advent of smart grids, utilities will need to be in far closer communication with their customers. If people’s consumption is approaching a threshold which could push them into a higher band, send them a text/email/IM/Tweet/all of the above (or whatever the customers preferred method of communication is) to let them know. If the customer’s consumption is lowest in their block/zipcode/subdivision/whatever, let them know, etc.

Communications is not something utilities have not traditionally needed to invest any time in. However as Bakersfield has shown, it will be a vital skill for utilities in the future, especially as the markets open up and people have a choice of who to buy their electricity from.

Smart Grid FUD: Its time to cut the crap

by

HI!.jpg
Greenmonk spends most of its time researching smart grid approaches and deployments.? I hired Tom Raftery largely because of his visionary take on the future of energy networks – Electricity 2.0. So you can imagine how happy I am that smart grid stimulus funds are being aggressively spent… on antivirus and encryption software. Yay – that’s just the market we want to track.

The “security industry” just loves to sell FUD. Its what they do. But the almost ghoulish lip-smacking around smart grids as the next great revenue opportunity is really off-putting. Is security important in a distributed energy network? Of course- but really its a small part of the puzzle, not the prize itself. With all this in mind I really enjoyed a post from EMC’s RSA stable this week. A guy called Sam Curry explains that customers are getting wise to the FUD, or are at least bored of it.

Sam: so?how’s your SmartMeter deployment going?
Security Director (SD): great! we’re rolling out about 1,000 a month
Sam: so, which ones are you using?
SD: COMPANY X
Sam: great, great, I heard they’re implementing encryption into their products
SD: yeah, I heard about that; but it’s not in the meters yet
Sam: ah — so what are you using for encryption?
SD: nothing
Sam: <gasp>
SD: uh, oh — here comes the FUD

And then it hit me?most of the time security people come in and try to scare customers and partners. What’s the point in that? Well?it’s a confidence scam. You scare people with FUD and then you comfort them with your brand

Sam seems like a good guy, a smart guy, and he understands that the real goal, the carrot as he calls it, is the hope of “better, greener power generation”. The real train wreck though will be our economies if we can’t fix some pressing energy concerns. The RSA post is excellent, and of course utilities need to rethink their entire risk profile and processes, just as IT does in the age of the internet. I am going to ping Sam and talk to RSA’s real smart grid offerings, so expect an update in the near future.

I want to start getting under the skin of smart grid deployments, and make sure we’re not substituting real smart grid innovation with unrelated product and service purchasing. After all- those stimulus funds… that’s our money. So we should be scrutinising the spend. There has to be more to smartgrids than AV.

Dude – Where’s My Customer? On Telcos, Utilities and Smart Grids. Towards a “SIM Card” for Smart Grids

by

SIM card reader
We had a really solid briefing with Convergys today. The firm sells software and services to telcos and utilities for customer care and billing – it has 80k employees worldwide, 550+ clients, and $3bn in revenue.

According to Greenmonk research most?utilities are failing to understand the the need to put the customer right at the center of their Smart Grid strategies. I pushed Kit Hagen, senior director of marketing, on the issue and he came back with a strong response.

“We often see utilities refer to IT as “the meter to cash process”- there is no customer in that. They’re calling the customer a meter.

Now you’re not going to just have disaggregated generation, but potentially a bunch of devices sitting behind the meter itself, and utilities should want to understand whats going on there. The world doesn’t end at the smart meter: think of kitchen appliances, for example.

This is an area the utilities need to start addressing. We can enable the technology, we can help the utilities…”

Electricity microgeneration, supported, for example, by feedin tariffs. How would a utility handle that from a billing perspective, send out two bills – one for consumption and one for production?

Kit’s colleague Mary Ann Tillman, director of product marketing, offered up a near perfect analogy for the kinds of challenge we’ll need to fix – mobile phones and SIM cards.

“Think of roaming. We need the same model for electric vehicles. How is someone that travels from London to Edinburgh in their EV going to be billed for recharging?”

Great analogy Mary – and that’s just within the UK… what about Pan-European requirements? For context – in case you have missed it, it turns out that EVs are one of the promising distributed storage mechanisms- the car battery becomes part of a “virtual utility”, as per Better Place.?We’re going to need the equivalent of GSM, and SIM card standards to support smart grid ecosystems of networked devices.

Not to put too fine a point on it – wireless communications companies are rather more used to this kind of model than traditional utilities, which could prove to be a competitive advantage. The role of the traditional utility billing engine fundamentally changes in smart grids – its definitely time to start refactoring these systems. T-Mobile is already driving a SIM to smart grid integration strategy.

Top down, customer takes what we give them just won’t work in smart grids. Roaming puts the customer first, and “number portability” will have to be part of the model. As we have been saying lately – smart grids and wireless networking are converging.

disclosure: Convergys is not a client.

Are utility companies ready for full smart grids?

by

Power management display

In the Smart Grid Heavy Hitters video interview series I have been publishing here on GreenMonk, one of the questions I ask all interviewees is, “What is a Smart Grid?” Almost all the interviewees talk about an infrastructure capable of full end-to-end, two-way communications. That is, communication from utilities down to the appliance level in-home, and from appliances back up to utilities.

Great. But what does this mean in practice and is this something utility companies have given enough thought to?

Utility companies currently typically take one meter reading per month. With the roll out of smart meters and smart grids that will change drastically. If a utility goes to 15 minute meter reads, we are talking about a shift from one meter read a month to around 2,880 meter reads a month (4 x 24 x 30 = 2,880).

This has huge implications for a utility company’s IT infrastructure. They will need to capture and store orders of magnitude more information than they have ever needed to previously.

On top of that, the information coming from smart meters is vastly more complex than the simple output of analog meters, as well. Particularly if the consumer is also a producer, selling energy back to the grid (via generation or from storage), getting rebates for lowering consumption in times of peak demand and/or getting roaming bills for charging up electric vehicles at public charging facilities, for example.

What will utility companies do with this new data?

Well, the primary use of this data will be for billing. Do utility companies have billing systems in place which are able to take in these vast quantities of data and output sensible bills?

Today’s bills are generated off that single monthly meter read, however bills generated from 2,880 meters reads a month (or even 720 – one meter read per hour) will be very different. They should be easy to understand, reflect the intelligence gained from the extra information and offer customers ways to reduce their next bill based on this.

Crucially too, utility companies will need to be pro-active in contacting people who go out of their normal pattern of usage/billing, otherwise we’ll see even more consumer backlash against smart grid roll-outs.

Obviously, transitioning away from paper bills to electronic ones will vastly enrich the possibilities utilities have with data presentation for customers as well as offering utilities ways to monetise their billing delivery (Google Adwords for bills anyone?).

On the consumer side, consumers will need to be able to see their energy consumption in real-time. Not only that, but to ensure that they act appropriately on the information, the user interface will be critical. A poor user experience will see a deluge of calls swamping customer care as people struggle to understand their consumption patterns. Or worse, mis-understand and send their bills soaring!

Consumers will need to be given ubiquitous, secure access to their energy consumption information. But more than that, consumers will also need to be given the tools to help them reduce their bills, without necessarily reducing their consumption (i.e. load shifting).

This will also necessitate a move to smart appliances by the consumer (appliances which can listen for price signals from the smart grid and modify behaviour according to a configurable set of rules). The Smart Appliances market is expected to reach $15bn by 2015 so the move to smart appliances can represent a new revenue stream for utility companies. Especially if they, with consumers consent, utilise energy-profile information from consumers smart meters to make more appropriate energy saving suggestions.

All of these changes require seismic shifts by utility companies both in terms of IT investments, but also in terms of their approach to customer care and communications.

Are they up for the challenges ahead? With the increasing liberalisation of energy markets and growth in consumer choices, they better be!

Smart Grid Heavy Hitters – Jon Wellinghoff, Chair of US Federal Energy Regulatory Commission – part 1

by

Jon Wellinghoff is the Chairman of the United States Federal Energy Regulatory Commission (FERC) – the FERC is the agency that regulates the interstate transmission of electricity, natural gas, and oil. As such, the FERC was the agency which Google Energy applied to for its licence to buy and sell electricity on the wholesale market, for example.

Shortly after his appointment as Chair of the FERC in 2009 by Barack Obama, Chairman Wellinghoff made headlines when he said

No new nuclear or coal plants may ever be needed in the United States… renewables like wind, solar and biomass will provide enough energy to meet baseload capacity and future energy demands

A chance came up recently to have him on this show, so I obviously jumped at it!

We had a great chat – so good, in fact that I turned it into two shows rather than edit any of it out.

In this first video we discussed:

  • What a smart grid is and its benefits
  • The backlash to early smart grid rollouts in Texas and California
  • How long it will be before we see full smart grids deployments

I will publish the second part of the interview next week.

In part two Chairman Wellinghoff will once again state that the US does not need to build any more coal or nuclear power plants, that renewables can meet the energy requirements of the US and he will discuss how electric car owners in some trials are being paid over $3,000 per annum for use of their batteries for grid regulation services by their utilities!
