Be a People Person

I have to admit it. Despite all the exciting new technologies out there, I am finding myself to be a people person when it comes to building smarter grids and more intelligent utilities. Granted, technology is rapidly developing and the utility industry is finding itself in the middle of more and more automation. However, people – from linemen to consumers – will remain critical components for delivering information-enabled energy.

In the many conversations I have with utilities and other industry thought leaders, we often start out talking about smart technology, but eventually our chats settle on people. People can ultimately make or break even the most promising technologies – from personnel and consumers adopting and using the technology to executives driving technology investments. So, in a world buzzing with new technologies, it is important to reacquaint ourselves with people. This article traces some of my conversations about what an intelligent utility is, how people fit in – both on the consumer and utility personnel side – and what the utility industry can do to better involve people. As is my usual style, I will serve up these critical subjects with a side of humor and perspectives outside the utility industry. So be prepared to learn more about yoga, Nashville, crystal balls and the telecom industry, too.

What Is An Intelligent Utility ?

Before understanding the importance of people, let’s take a moment to understand where people fit into smart grids and intelligent utilities. Utilities are no longer exempt from change. From economic stimulus plans to carbon controls, to the impending electric vehicle flood, we must face the fact that the utility industry will undergo significant changes in the coming years, months and even minutes. Now, it is not so much a question of what changes will happen, but how – and how well – will the utility industry adapt to these changes?

A frequent answer to this question has been a “smart grid,” but most smart grid discussions inevitably lead to these questions:

  • How do we get to a smart grid?
  • When do we know when we are there?
  • What is a smart grid anyway?

These are not easy questions. Many groups define the smart grid, but how can you tell when a utility has one? Better understanding this challenge requires an unusual, but useful comparison: Nashville and Nirodha – a state of mind in yoga. Let’s say you are traveling to Nashville. You would see landmarks that you could only find in Nashville, such as the Grand Ole Opry, B.B. King’s Blues Club and the Bell- South Tower. Smart grid landmarks, however, are harder to come by. Utilities can install smart meters and other smart sensors on their grid, but having these technologies does not necessarily mean they have arrived at a smart grid. To add to the confusion, other smart grid components, such as demand response, distribution automation and more advanced metering, have already been around for years.

Although such technologies can support a smarter grid, the smart grid is more than just acquiring certain technology landmarks. So, although it is a nice place, you shouldn’t just think Nashville when you think smart grid. Think Nirodha. For those of you who aren’t yoga enthusiasts, Nirodha is a state of mind in yoga in which you become more focused and aware of an object. In the case of a utility, the object is primarily the transmission and distribution network. As a utility becomes more aware and ultimately more knowledgeable about its network, it can make better decisions about its operation.

Furthermore, as a company builds more knowledge about its grid, it develops not only a smarter grid, but also a more intelligent utility. An intelligent utility overlays information on energy that goes beyond the transmission and distribution network all the way from generation to end users, maximizing its reliability, affordability and sustainability. Essentially, utilities are delivering information-enabled energy. And technology is just one piece for delivering this sort of energy. Here is a quick run-down of the key components in an intelligent utility:

  • Process & technology: Utility objectives and their impact on business process change and smart technology deployment;
  • Economic models: The challenges and opportunities of new paradigms. So this is not just the changes involved with upgrading a technology – like a customer information or geographic information system – but the changes from initiatives like electrifying transportation and microgrids that could radically alter utility companies and the roles of generators and consumers;
  • Finance: Investment trends associated with smart technologies;
  • Public policy: The impact of politics on energy – including efforts by regulators and legislators. These groups ultimately set up the framework that determines whether and how intelligent initiatives move forward; and
  • People: The knowledge, skills and abilities required for both the workforce and consumers in an information-enabled environment.

Involving Workforce

The rest of this article will take a little bit closer look at the last component – people. As we move toward information-enabled energy, the utility workforce will undergo some significant changes – from new job titles, to new knowledge, skills and abilities (KSAs), to new people joining utility companies from other industries.

Ryan Cook, vice president of the employment services division at Energy Central, has pointed out that “In today’s utilities, employee KSAs are based primarily on providing electrical power as a product. These KSAs support the rules-based, process-oriented, functionally structured, and cost-focused business needs of today’s utility. In the future, however, there will be a massive paradigm shift from providing just a product to providing customers with customizable services and solutions for their unique energy needs. The result will be a shift toward KSAs that support a more agile, innovative, collaborative, cross-functional, service-oriented utility of the future. Employees will need to deal with constantly evolving technology.”

So, digitizing the grid will change personnel needs. We know that much, but the big unknown is how exactly will those needs change? And where is a good crystal ball when you need one? Since my snow globe wasn’t working, I thought about other industries that have gone through a digital revolution, which brought me to the telecom and cable industry. I learned much from Alan Babcock, president of Broadband Training Associates. As this industry digitized its grid over the last 13 years and began to focus more on services as opposed to products, it saw significant workforce changes – touching everyone from field crews, to executives, to marketing folks – that could happen to the utility industry as well.

Out In the Field

Before digitizing the telecom and cable industry, many field crews were still pencil and paper, and some still are today. But digitization changes weren’t just about figuring out how to use a truck-mounted laptop. The workforce has a whole new job to do today. In particular, they now have to troubleshoot new problems on multiple services in the network and become experts at devices on an end user’s premise.

Before digitization, field crews dealt with one service – like video in the cable industry – but now they have to balance multiple services in the same network, including voice, data and video. The decisions you make for one service will ultimately impact the others. So, with multiple services, it changes how you do regular maintenance, how you troubleshoot networks, and how you take the network down to make repairs. On top of that, technicians may not be able to take down certain parts of the network because of service level agreements with customers.

Besides dealing with multiple services, field crews have to better understand the devices that extend into customer premises – including modems for Internet or set-top boxes for cable. It can be embarrassing for a telecom or cable company when the consumer knows more about consumer devices than the technician.

Back In the Office

Digitizing the network not only changed KSAs for field crews, but has changed things in the back office of telecom and cable companies as well. These changes occurred in the areas of marketing, customer service, planning and IT.

  • Marketing to customers: Digitization provides cable and telecom companies with increased visibility into the customer premises. This is not only helpful with determining whether customers have service, but also understanding their entertainment preferences. These companies now better understand what entertainment you watch and when you watch it. Ultimately, they have a lot of information at their disposal to be able to better market to you. Telecom companies, however, weren’t traditionally in the entertainment industry, so better marketing to consumers required a new group of employees from outside telecom.
  • Customer service: Customer service has changed in many ways with the digitization of the telecom and cable industry. With a smarter grid, the utility industry often focuses on benefits that it will bring to the customer representatives in terms of access to more information, but there are other benefits to consider as well. An interesting twist in the telecom and cable industry is that as the network gets more complex, a customer service agent’s job gets somewhat simpler. Essentially, customer service representatives have to recall fewer technical details about the network than they did before. It is not as important that they understand how the networks function because they have better visibility into the premise and have more intelligent systems to walk them through trouble-shooting problems.
  • Capital and strategic planning: Digitization has changed the planning time horizon and knowledge requirements for telecom and cable executives. They must factor in the dizzying technology advancements in the industry; think about the rapid movement from 2G to 3G to 4G networks and beyond. The five-year plan now has to be the three-year plan. From a planning standpoint, they also need to better understand the networks in order to figure out how to best utilize and benefit from services that are enabled by those networks.
  • Designing and maintaining IT systems: Aside from learning how to design and maintain new technologies and systems, the technology personnel in telecom and the cable industry have learned some important lessons as they digitize the networks. The first is to more carefully consider the usefulness of new technologies. If a new technology comes along, it doesn’t mean that it has to be used. If a new technology does make sense to use, technology personnel need to consider the human aspects involved with making that change, including change management and making sure the technology is ready when people actually begin using it.

Involving Customers

Not only will the intelligent utility impact its own personnel, but it will impact consumers as well. In particular, utilities will have to help consumers to understand the value of changes and get them to participate in intelligent initiatives.

As I am sure many of you have realized from conversations with friends and family, many people do not understand smart grid benefits or even how the grid really works. Although more people are starting to realize the value, a key challenge is how to get consumers to grasp these concepts and support a smarter grid and more intelligent utility. Utilities have to figure out how to make these things real for people – and are finding many ways to do that. As one utility executive pointed out, “A technology center served to convince our community stakeholders and our PUC that this appears to be a worthwhile journey. The awareness to the consumer was a tremendous value. They were able to start thinking of the value of what we’re trying to build rather than what we’re trying to build.”

Many intelligent initiatives, from demand response to real-time pricing, focus on the end user and require some level of consumer effort. Consumer participation is key for success, but utilities are finding it challenging to get participation. Solutions range from more automation in controlling household appliances and HVAC systems to competition between neighbors regarding energy consumption, but there is still much work to be done in this area, depending on consumer demographics.

Be A People Person

It is easy to get caught up in the technology hype, but as the examples above demonstrate, it is important to keep people in the equation when looking at smart initiatives. People play a key role in determining their success or failure. By preparing for the people factor and considering them in smart initiatives, utilities can better ensure the adoption and success of new technologies and processes.

How Intelligent Is Your Grid?

Many people in the utility industry see the intelligent grid — an electric transmission and distribution network that uses information technology to predict and adjust to network changes — as a long-term goal that utilities are still far from achieving. Energy Insights research, however, indicates that today’s grid is more intelligent than people think. In fact, utilities can begin having the network of the future today by better leveraging their existing resources and focusing on the intelligent-grid backbone.

DRIVERS FOR THE INTELLIGENT GRID

Before discussing the intelligent grid backbone, it’s important to understand the drivers directing the intelligent grid’s progress. While many groups — such as government, utilities and technology companies — may be pushing the intelligent grid forward, they are also slowing it down. Here’s how:

  • Government. With the 2005 U.S. Energy Policy Act and the more recent 2007 Energy Independence and Security Act, the federal government has acknowledged the intelligent grid’s importance and is supporting investment in the area. Furthermore, public utility commissions (PUCs) have begun supporting intelligent grid investments like smart metering. At the same time, however, PUCs have a duty to maintain reasonable prices. Since utilities have not extensively tested the benefits of some intelligent grid technologies, such as distribution line sensors, many regulators hesitate to support utilities investing in intelligent grid technologies beyond smart metering.
  • Utilities. Energy Insights research indicates that information technology, in general, enables utilities to increase operational efficiency and reduce costs. For this reason, utilities are open to information technology; however, they’re often looking for quick cost recovery and benefits. Many intelligent grid technologies provide longer-term benefits, making them difficult to cost-justify over the short term. Since utilities are risk-aware, this can make intelligent grid investments look riskier than traditional information technology investments.
  • Technology. Although advanced enough to function on the grid today, many intelligent grid technologies could become quickly outdated thanks to the rapidly developing marketplace. What’s more, the life span of many intelligent grid technologies is not as long as those of traditional grid assets. For example, a smart meter’s typical life span is about 10 to 15 years, compared with 20 to 30 years for an electro-mechanical meter.

With strong drivers and competing pressures like these, it’s not a question of whether the intelligent grid will happen but when utilities will implement new technologies. Given the challenges facing the intelligent grid, the transition will likely be more of an evolution than a revolution. As a result, utilities are making their grids more intelligent today by focusing on the basics, or the intelligent grid backbone.

THE INTELLIGENT GRID BACKBONE

What comprises this backbone? Answering this question requires a closer look at how intelligence changes the grid. Typically, a utility has good visibility into the operation of its generation and transmission infrastructure but poor visibility into its distribution network. As a result, the utility must respond to a changing distribution network based on very limited information. Furthermore, if a grid event requires attention — such as in the case of a transformer failure — people must review information, decide to act and then manually dispatch field crews. This type of approach translates to slower, less informed reactions to grid events.

The intelligent grid changes these reactions through a backbone of technologies — sensors, communication networks and advanced analytics — especially developed for distribution networks. To better understand these changes, we can imagine a scenario where a utility has an outage on its distribution network. As shown in Figure 1, additional grid sensors collect more information, making it easier to detect problems. Communications networks then allow sensors to convey the problem to the utility. Advanced analytics can efficiently process this information and determine more precisely where the fault is located, as well as automatically respond to the problem and dispatch field crews. These components not only enable faster, better-informed reactions to grid problems, they can also do real-time pricing, improve demand response and better handle distributed and renewable energy sources.

A CLOSER LOOK AT BACKBONE COMPONENTS

A deeper dive into each of these intelligent grid backbone technologies reveals how utilities are gaining more intelligence about their grid today.

Network sensors are important not only for real-time operations — such as locating faults and connecting distributed energy sources to the grid — but also for providing a rich historical data source to improve asset maintenance and load research and forecasting. Today, more utilities are using sensors to better monitor their distribution networks; however, they’re focused primarily on smart meters. The reason for this is that smart meters have immediate operational benefits that make them attractive for many utilities today, including reducing meter reader costs, offering accurate billing information, providing theft control and satisfying regulatory requirements. Yet this focus on smart meters has created a monitoring gap between the transmission network and the smart meter.

A slew of sensors are available from companies such as General Electric, ABB, PowerSense, GridSense and Serveron to fill this monitoring gap. Tracking everything from load balancing and transformer status to circuit breakers and tap changers, energized downed lines, high-impedance faults and stray voltage, and more, these sensors are able to fill the monitoring gap, yet utilities hesitate to invest in them because they lack the immediate operational benefits of smart meters.

By monitoring this gap, however, utilities will sustain longer-term grid benefits such as reduced generation capacity building. Utilities have found they can begin monitoring this gap by:

  • Prioritizing sensor investments. Customer complaints and regulatory pressure have pushed some utilities to take action for particular parts of their service territory. For example, one utility Energy Insights studied received numerous customer complaints about a particular feeder’s reliability, so the utility invested in line sensors for that area. Another utility began considering sensor investments in troubled areas of its distribution network when regulators demanded that the utility raise its System Average Interruption Frequency Index (SAIFI) and System Average Interruption Duration Index (SAIDI) ratings from the bottom 50 percent to the top 25 percent of benchmarked utilities. By focusing on such areas, utilities can achieve “quick wins” with sensors and build utility confidence by using additional sensors on their distribution grid.
  • Realizing it’s all about compromise. Even in high-priority areas, it may not make financial sense for a utility to deploy the full range of sensors for every possible asset. In some situations, utilities may target a particular area of the service territory with a higher density of sensors. For example, a large U.S. investor-owned utility with a medium voltage-sensing program placed a high density of sensors along a specific section of its service territory. On the other hand, utilities might cover a broader area of service territory with fewer sensors, similar to the approach taken by a large investor-owned utility Energy Insights looked at that monitored only transformers across its service territory.
  • Rolling in sensors with other intelligent grid initiatives. Some utilities find ways to combine their smart metering projects with other distribution network sensors or to leverage existing investments that could support additional sensors. One utility that Energy Insights looked at installed transformer sensors along with a smart meter initiative and leveraged the communications networks it used for smart metering.

While sensors provide an important means of capturing information about the grid, communication networks are critical to moving that information throughout the intelligent grid — whether between sensors or field crews. Typically, to enable intelligent grid communications, utilities must either build new communications networks to bring intelligence to the existing grid or incorporate communication networks into new construction. Yet utilities today are also leveraging existing or recently installed communications networks to facilitate more sophisticated intelligent grid initiatives such as the following:

  • Smart metering and automated meter-reading (AMR) initiatives. With the current drive to install smart meters, many utilities are covering their distribution networks with communications infrastructure. Furthermore, existing AMR deployments may include communications networks that can bring data back to the utility. Some utilities are taking advantage of these networks to begin plugging other sensors into their distribution networks.
  • Mobile workforce. The deployment of mobile technologies for field crews is another hot area for utilities right now. Utilities are deploying cellular networks for field crew communications for voice and data. Although utilities have typically been hesitant to work with third-party communications providers, they’ve become more comfortable with outside providers after using them for their mobile technologies. Since most of the cellular networks can provide data coverage as well, some utilities are beginning to use these providers to transmit sensor information across their distribution networks.

Since smart metering and mobile communications networks are already in place, the incremental cost of installing sensors on these networks is relatively low. The key is making sure that different sensors and components can plug into these networks easily (for example, using a standard communications protocol).

The last key piece of the intelligent grid backbone is advanced analytics. Utilities are required to make quick decisions every day if they’re to maintain a safe and reliable grid, and the key to making such decisions is being well informed. Intelligent grid analytics can help utilities quickly process large amounts of data from sensors so that they can make those informed decisions. However, how quickly a decision needs to be made depends on the situation. Intelligent grid analytics assist with two types of decisions: very quick decisions (veQuids) and quick decisions (Quids). veQuids are made in milliseconds by computers and intelligent devices analyzing complex, real-time data – an intelligent grid vision that’s still a future development for most utilities.

Fortunately, many proactive decisions about the grid don’t have to be made in milliseconds. Many utilities today can make Quids — often manual decisions — to predict and adjust to network changes within a time frame of minutes, days or even months.

no matter how quick the decision, however, all predictive efforts are based on access to good-quality data. In putting their Quid capabilities to use today — in particular for predictive maintenance and smart metering — utilities are building not only intelligence about their grids but also a foundation for providing more advanced veQuids analytics in the future through the following:

  • The information foundation. Smart metering and predictive maintenance require utilities to collect not only more data but also more real-time data. Smart metering also helps break down barriers between retail and operational data sources, which in turn creates better visibility across many data sources to provide a better understanding of a complex grid.
  • The automation transition. To make the leap between Quids and veQuids requires more than just better access to more information — it also requires automation. While fully automated decision-making is still a thing of the future, many utilities are taking steps to compile and display data automatically as well as do some basic analysis, using dashboards from providers such as OSIsoft and Obvient Strategies to display high-level information customized for individual users. The user then further analyzes the data, and makes decisions and takes action based on that analysis. Many utilities today use the dashboard model to monitor critical assets based on both real-time and historical data.

ENSURING A MORE INTELLIGENT GRID TODAY AND TOMORROW

As these backbone components show, utilities already have some intelligence on their grids. now, they’re building on that intelligence by leveraging existing infrastructure and resources — whether it’s voice communications providers for data transmission or Quid resources to build a foundation for the veQuids of tomorrow. In particular, utilities need to look at:

  • Scalability. Utilities need to make sure that whatever technologies they put on the grid today can grow to accommodate larger portions of the grid in future.
  • Flexibility. Given rapid technology changes in the marketplace, utilities need to make sure their technology is flexible and adaptable. For example, utilities should consider smart meters that have the ability to change out communications cards to allow for new technologies.
  • Integration. due to the evolutionary nature of the grid, and with so many intelligent grid components that must work together (intelligent sensors at substations, transformers and power lines; smart meters; and distributed and renewable energy sources), utilities need to make sure these disparate components can work with one another. Utilities need to consider how to introduce more flexibility into their intelligent grids to accommodate the increasingly complex network of devices.

As today’s utilities employ targeted efforts to build intelligence about the grid, they must keep in mind that whatever action they take today – no matter how small – must ultimately help them meet the demands of tomorrow.
