A botched and ill-informed column in the L.A. Times points out a painful reality -- one of the toughest hurdles to the Smart Grid may be the job of explaining it to the public. That job is made even more difficult by the "guilty until proven innocent" attitude of many self-proclaimed consumer advocates.Under the theory that California often leads the way, utility professionals in other parts of the country may face similar wrong-headed attacks when they roll out their own smart metering initiatives.
On April 20th, columnist David Lazarus wrote that California's three biggest utilities (SCE, SDG&E and PG&E) had all opted for smart meters with less expensive, lower-speed connections. He claimed those meters could be outdated before they are even operational because they would not "speak the same language" as the smart grid of the future. (See link below to read the full article.)
The LA Times declined to print a response, but here is what we would like California readers to know:
David Lazarus’ April 20, 2008 Consumer Confidential reaches an erroneous conclusion – that the new meters being installed by Southern California utilities are outdated the day they are installed. He concludes that California electric consumers will see few benefits from the new meters because they are not connected by broadband.
As the journal of record for the smart grid sector, SmartGridNews.com follows developments throughout North America. We can say with authority that the current Southern California Edison metering installation is far from wrong-headed. It is a model for the rest of the electric power industry.
Mr. Lazarus made at least three incorrect assumptions. We assert that:
Narrowband and broadband can communicate just fine. Lazarus claimed that narrowband meters cannot talk to a broadband smart grid. Broadband simply refers to the capacity of a communications platform. Broadband is to narrowband as an eight-lane highway is to a two-lane street. Claiming that low-speed meters cannot connect to a broadband grid is like claiming that drivers on a city street cannot merge onto an Interstate.
Meters do not require broadband to be valuable. Lazarus implied that low-speed meters would not deliver any value to consumers. The value of two-way messaging does not disappear just because the communications path is slow. A cell phone on a slow analog network may not download videos as quickly as a faster 3G network, but it is perfectly adequate for voice conversations. Likewise, narrowband meters are perfectly adequate for many Smart Grid applications. Indeed, most of the futuristic ideas mentioned by Mr. Lazarus -- real-time pricing, outage management -- are being accomplished today using narrowband meters.
State and federal policy do not mandate overbuilding. It's not usual to see "civilians" get it wrong when it comes to the complexities of the electric power infrastructure. But it was astounding to read Mr. Lazarus' proclamation that putting short-term economics ahead of long-term technology "runs contrary to federal and state policy." In reality, one of the most important roles of utility regulation is to ensure that ratepayers do not get saddled with long-term technology pipe dreams. Regulators rightfully demand that utilities prove the value and payback of their technology investments.
In this case, Mr. Lazarus didn't just get it wrong, he got it embarrassingly and foolishly wrong.
Lazarus admits that broadband meters would cost as much as five times more, but believes the utilities should burden ratepayers with this expense because "the real question is how smart grids will be used five or 10 years from now." According to Mr. Lazarus,
California ratepayers should be angry they will be paying $4.6 billion for their new meters. Instead, they should be clamoring to pay up to five times more ($23 billion) to have broadband meters instead. Those broadband meters wouldn't be able to do anything today that can't be accomplished by the narrowband versions, but Californians should pay the extra money "to be technologically prepared for all the bells and whistles" that may show up in 10 years.
By his logic, we should all have installed broadband Internet connections back in 1995 (when they were ultra-expensive) just in case something like YouTube might get invented in 2005. (Don't know about you, but we're feeling pretty smart that we waited until broadband prices got much lower and there was a reason to sign up). By that same line of thinking, maybe we should all build heliports on our roofs today in case gyrocopters become popular in 2018.
Southern Californians should be thankful that their utilities are acting on the need for a Smart Grid now. As Jim Rogers, the CEO of Duke Energy states: ‘the Smart Grid is like building a medieval cathedral, the generation that designs it will never see it completed.” Utilities such as Southern California Edison, San Diego Gas & Electric and Pacific Gas & Electric are ahead in planning for a Smart Grid. They also actively share their results. We have sat in meetings where representatives from small utilities have stood up and thanked those utilities for their vision and sharing of information. They may not get it right all the time (who does), but on this one – Mr. Lazarus has it wrong and for once, California consumers will have it right.
LA Times April 20 2008: 'Smart meters' may soon be outdated
| We really don't know |
| Philip: I agree with you that the LA Times' David Lazarus is off base in definitively declaring that the CA IOUs' approach to AMI and Smart Grid is flawed in not adopting a broadband approach. At the same time, I am a little surprised at your unequivocal endorsement of the IOUs' approach. It may be true that a narrowband approach to AMI will suffice, but the truth is that we really don't know how the Smart Grid will ultimately unfold. We don't know if plug-in electric hybrid vehicles will be adopted en masse, if the price of oil will stay well above $100 a barrel, if central-station generation technologies like nuclear and clean coal will be the backbone of all generation, etc. Because of these uncertainties, the smart thing to do may well be what most companies are doing, dipping a toe cautiously in the water,making some long-term plans, but being careful about committing to large investments until and unless the regulator and customer clearly share in the decisions. In that regard, although you praise the CA ISOs for being pioneers in this effort, I think that Californians are taking a risk (again) by being first to try this and by proceeding so quickly. What's the rush, other than the pressure exerted by state agencies and activists? |

| AMI and Smart Grid Not One in the Same |
| Advanced meters are a worthwhile investment for reasons having nothing to do with the "Smart Grid" concept. They provide customers, regulators and utilities with more fine-grained detail about energy use. They can be read frequently and automatically, which should ultimately save time and money. They should allow the California ISO to dramatically reduce the current lag of nearly three months between the date market transactions are executed and the date they are finally settled (which will free up large amounts of collateral). However it's my opinion that advanced meters don't have to be smart and they don't have much to do with a "Smart Grid'. Combined with some form of dynamic or time-of-use pricing, they will provide consumers with the information they need to make better choices about energy use. AMI is about smart consumers, not a Smart Grid. |

| Never |
| Technology tends to continue to do what it was originally deployed to do, until it fails. Only the capabilities surrounding it can make it obsolete. Without the basic technology, the services that make it valuable won't be developed, and we won't need more advanced technology -- nor will we have its benefits. If we always waited for the ultimate technology, none of us would yet be connected to the internet today. Just getting smart meters in place will be a big step forward for the smart grid. http://energypriorities.com/entries/2008/06/smart_meters_lazarus.php |

| AMI and Smart Grid: Chicken or the Egg |
| I don't think LA Times' article is totally off base. It's the question of ROI for the California ISO's and I'm sure at the end of the day, it was the cost of AMI won over the long term benefit of the Smart Grid. I have done projects for "Optimal Network of the Future", "AMI business case" and a "Smart Grid" and it is interesting to see depending on the project sponsorship who wins out. In California regulatory push created urgency and I'm sure narrowband approach was part of the solution chosen based on time/cost and to certain extent the AMI vendors. Let's be honest, AMI vendors are not to eager to share their "Roads" with everyone!!! Don't believe that? Try asking for standard IP based smart meters. It's never an easy answer!!! Phil Bane's thought of "open roads" is far from a reality. And the comparison of the cellular world with analog and digital convergence was not as easy as Phil noted. End of the day, it's the question of what came first, chicken or the egg? And really if we want to do it right, get the right sponsor for the project. Look at all the use of the AMI, Smart Grid or Optimal Network, what ever else you want to call it, base the project on the overall value to the consumer and the company. I salute CenterPoint for their approach with great sponsorship!! Though far from over, it's a great start. |

| Communications is Key for Smart Grid |
| I live in Washington State and can only wish my utility company would be as proactive as Southern California Edison. Unfortunately, the LA Times artice points out something that utilities and their vendors are ignoring--if we don't help educate the public and include a communications plan in smart grid solutions and demand response programs, opportunists such as the Times columnist, can have a field day without that "balanced" voice explaining why he is wrong. As a communications manager for a company that offers demand response solutions, I nearly choked when I read the column, and plan to use it as an example of good journalists gone bad in future presentations. Thanks for your voice on this. |

| Confusion of purposes |
| Smart meters are only step one to integrating demand side management to grid control. They provide utilities (not customers) the ability to understand end-use energy patterns. Ultimately they will lead to better allocation of costs, not to better control. It is all of the other smart grid functions like centralized energy management, auto-DR and sophisticated appliances that will ultimately yield smart-grid benefits. Each one of these functions will have multiple iterations before we develop a robust, electronically controlled, consumer-focused grid. And yes, some of the investment will be obsolete in the process. However, broadband is not the gating item. Consumer acceptance is. Only when consumers--residential, industrial and commercial--are involved in the dispatch decisions, will we have a smart grid. Broadband really has little to do with that. |

| Ignorance |
| ....It amazes me how ignorant the people are who are supposed to be "in the know" about what is availablein the electric meter and grid infrastructure arena. Enel in Italy, Vattenfall in Sweden, and now Duke Energy in the US (to name a few)have ALL gone with the NES solution from Echelon Corp.in San Jose California. http://www.echelon.com/ The future proof smart meter solution is already up and running all over the world. -E |

| Speed = Smart? |
| Are the utilities planning to increase the speeds of the entire data acquisition network (RTU- Host)? Answer to the question throws light on the problem we are addressing. The smartness of the grid comes from the intelligence that is built into the system to interpret the information. Meter is just a component and speed is an attribute of the component. |

| I won't buy the iPhone - I'll wait for iPhone.5 |
| This discussion illustrated two of the issues facing grid operators that are relatively new: the dilema of having to educate the public about grid technology (until a couple of years ago most of the public couldn't even spell ISO!) Things are different now and the void left by the industry is being filled by a lazy/ill-informed press. Second, now that 'high-tech' is core to grid developments some folks wil always saiy 'wait - it will get better, cheaper, more multi-functional...' etc. Thing is, we need to build by increments and the technology will move along with - and sometimes even ahead of - the industry. That's not a prescription for inaction - just caution caution and better informed decisions. |

| A Future-Ready but Cost-Effective AMI Architecture |
| After spending significant time and energy in researching the optimal architecture for the smart grid, I believe a few distinctions need to be made, because in this case the devil is in the details: A. When referring to broadband meters, it seems that Mr. Lazarus had some advanced meter functionalities in mind, but today's most advanced functionalities – such as Time Of Use, Remote Disconnect and remote firmware upgrade - are available in meters with a narrowband communications interface. B. When referring to the network, again a distinction needs to be made between the part of the network directly connected to the meters, and the part which is used for backhaul of the traffic between the meters and the utility's aggregation point (which typically covers thousands of meters). A broadband connection to every meter is an overkill, which significantly increases the network costs, but on the other hand using narrowband all the way to the aggregation point results in significant communication bottlenecks, which do not allow the system to meet the utility's performance requirements. Based on detailed simulations of an AMI communications network, we've concluded that the most optimal and cost effective architecture is to use a dual-layered network approach. The first layer is a narrowband LAN which connects to every 30 – 50 meters, and the second is a broadband WAN, which aggregates the traffic from every LAN. This approach is also future-proof, because the WAN bandwidth is available to support new applications as they are introduced. If needed, the number of meters per LAN can be reduced in the future to increase the available bandwidth per household. This is a pay-as-you-grow approach, which will only require incremental and gradual future investment, and only when you need it. |

| Broadband above all |
| Dear Phil, While there's much more carrying capacity to broadband than utilities need -- now --, there's much more carrying capacity that utilities can use now. Optical fiber, for example, doesn't emit spurious electronic radiation and doesn't get perturbed by electronic radiation, so it could easily support intense, mission critical applications by utilities. The excess bandwidth may be initially an embarrasment of riches, but I believe utilities can through partnerships and tenancies with content providers harvest those riches and deliver superior customer service. Proactive telecommunications development is very much in the long-term interest of utilities, their customers, their communities, and the nation. |

| It is called Integration Baby! |
| Smart Meters, Smart Grid, Smart IED's, Substations and Generation Plants. It all has to work together, for the utility, and for the customer. The California model did not work for de-regulation, but maybe they can learn something from Duke and Echelon! It used to be the relays (P&C) that drove everything in substation automation. Whatever it takes, the infrastructure is falling down and we need automation integration from home to substation to plant and back. |

| Demand Management Via AMI |
| Cable, DSL, mobile, and now AMI? We could do this work with any of them. The 1st 3 aren't available, reliable, or secure enough yet so the utilities must build their own network. Will they always need to have their own network? |

| Next Gen Smart Meters / BPL |
| All very good points made but the reality is if you think smart meters are actually smart now, just wait for the next generation. Telepathx is working with smart meter / BPL & Wifi OEMs on expanding and leveraging their product capabilities to actully devilver a "super smart Grid. One that can actaully detect faults on the distribution grid while simutainiously providing essential off grid functions. it all about leveraging the infrastucture, no matter what protocol or frequency. somthing Echelon & Itron failed to identfy. If you want to sell it to the public, leverage your platforms, go beyond the meter, to the grid and beyond. James Eades CEO Telepathx Ltd |
