Line-LossLine-Loss is a constant battle for electric utility companies regardless of their size. What once was anacceptable level for line-losses can no longer be acceptable. According to the Department of Energy1,it is estimated that United States utilities lost 6.
This can result in multi-million dollar losses. In a letter to U. Resistance to the flow of electrical current in the distribution and transmission system causes a portion of energy, typically 7 percent, to be lost in the form of heat, resulting in higher emissions for the same amount of delivered electricity.
In fact, RUS reported cooperative line losses at 4. With their consumers widely dispersed 6. The total for the United States is as follows: Energy Information Administration website, Date of Data: April CausesThere are numerous issues4 that cause line-loss for utilities including: Federal InvolvementThe federal government began the process of mandating Smart Grid technology with the BushAdministration.
The Obama Administration has not missed a beat in their push for Smart Gridtechnology. There are 4 primary goals mentioned in this press release: Better alignment of economic incentives to boost development and deployment of smart-grid technologies 2.
A greater focus on standards and interoperability to enable greater innovation 3. Empowerment of consumers with enhanced information to save energy, ensure privacy, and shrink bills 4. Improved grid security and resilienceIn an effort to meet these goals the Obama Administration released these public and private-sectorinitiatives: The launch of Grid 21, a private sector initiative to promote consumer-friendly innovations while ensuring proper privacy safeguards and consumer protections.
Grid 21 will help consumers get better access to their own energy usage information so that they can take advantage of new tools and services to manage their energy use and save on their utility bills.
The Administration is committed to working with States and stakeholders to ensure all Americans can take advantage of new tools and services to manage their energy use and save on their utility bills. With proper privacy safeguards and consumer protections, a smarter electricity system can benefit all consumers.
Expanded partnerships to continue working with States and stakeholders, including an initiative to share lessons learned from Recovery Act smart grid investments, a series of regional peer-to-peer stakeholder meetings, and updated online resources available at: Energy, to improve Federal coordination and ensure timely review of proposed renewable energy projects and transmission lines, to ensure that renewable energy can power cities and towns across America, and to increase reliability and save consumers money by modernizing the grid.
These initiatives are the focus of the American Recovery and Reinvestment Act of 6 allocation toSmart Grid issues. The Green Energy initiatives involving Wind and Solar power will play a role inreplacing the fossil fuel generation of the past as we move forward in upgrading our transmission gridin the United States.
Securing the Smart Grid
Upgrading the transmission grid is a necessary element that should have been started a long timeago. If the transmission is not upgraded then maximum results cannot be achieved by the smart grid.
ABB7 wrote a white paper on these solutions listed above. Thesuperconductors called HTS high temperature superconducting carry a line loss of. Distribution SolutionsABB also listed other paths to improved efficiency. Here are those proposed paths: Solving these issues first will result in the highest Returnon Investment. As the Smart Grid matures, more devices will be brought into the fold for monitoring. Transformers 7. They should be ready in the next 5 years formanufacturing and deployment to utilities.
Soon to follow are other protective devices withmonitoring systems for the distribution conductors.

Data Generated by the Smart GridNow we have the question, how is the data gathered and organized. Geographic Information Systems GIS becomes an essential tool for the organization and analysis of data. Without a GIS in place theanalysis of data, creation of reports, and gathering of data becomes difficult.
It is important that thedata from the different sources is interoperable with each other. The best way to ensure thisinteroperability is to require that vendors providing the Smart Grid components be MultiSpeak www.
The MultiSpeak Specification is a key industry-wide standard for realizing the potential of enterprise application interoperability. The MultiSpeak Specification is the most widely applied de facto standard in North America pertaining to distribution utilities and all portions of vertically-integrated utilities except generation and power marketing.
It is currently in use in daily operations of more than electric cooperatives, investor-owned utilities, municipals, and public power districts in at least 15 different countries.
The Initiative has developed and continues to expand the MultiSpeak Specification for Interoperability a specification that defines standardized interfaces among enterprise software applications commonly used by electric utilities.
GIS is the foundation of the organization of data. All of these activities createmore efficiency in the utility. Utilities are constantly being bombarded with accusations of rising utilityrates from their customers.
With the reduction of line-loss those rates could come down. In order toreduce line-loss efficiently the data must be organized, presented and analyzed in such a way thatissues on the distribution system are solved in a systematic approach.
GIS allows this systematicapproach to be developed and shows trends and patterns graphically. As we move forward with the Smart Grid, the installation and use of GIS is becoming an essential toolthat utilities cannot live without.
The utilities that see this vision before investing in Smart Gridupgrades that are not interoperable, will have saved not only money but aggravation as well.
Outage ManagementThe number one area of lost revenue in electrical utilities are outages, planned or unplanned. Outageshave been a constant in the past and will continue to be a constant into the future. We can manage theseoutages more efficiently in the future by utilizing and analyzing the data provided to utilities during theoutage s from one location.
Data SourcesWhat are the possible data sources for the electrical utility?
When datasources are not connected together seamlessly, more employees are needed to manage the data sources. Not all utilities will have all of these data sources but all utilities have at least some of these sources.
Smart Grid has been added
All utilities have some sort of mapping whether or not the mapping has been converted into a digitalformat depends on the utility. All utilities have customer information in some form or another. We find that most utilities we 9. These componentsare typically not integrated together. IntegrationIntegration of data is the key to managing outages efficiently. GIS is the integrator of data sources. Forelectrical utilities, it is important to note the how critical having all data sources MultiSpeak multispeak.
If the interoperability isthere from the beginning the marriage of all the data will be seamless in the GIS making the integrationeasier and more cost effective for the utility in the integration process.
What is Kobo Super Points?
GIS joins all the data sources together. It truly is the hub. From this hub the decision makers can makedecisions at a high accuracy rate and faster than ever before.
The reason for this is because the data isdisplayed on a map. So the trends and patterns become very easy to discern on the fly. The number ofemployees now allocated to managing the data sources has dropped from 7 to 4, saving money andresources for the utility.
Once the GIS becomes the hub creating custom reports for analysis becomesvery straight forward and also reduces man-hours in creating the report because the data is broughttogether in one location. Managing the OutagesDispatchers for utilities process a tremendous amount of information during an outage event. Who is out of power Where are the crews Tree and Line Which crews have been assigned to which areas Are crews clear of a line being re-energized Answering phone calls coming in from customers to report outages Communicating with crews Planning where to send crews as the outage event progressesWithout GIS this job can be chaotic at best at the beginning of an outage event.
With GIS this job isvery hectic at worst. See how a GIS makes life easier on the dispatcher by bringing together the data sources shown below: Figure 3As you can see in Figure 3, IVR and Web applications help in the communications with customersimproving the service customers receive from the utility. AVL allows the dispatcher to see where thecrews are located at all times to improve safety of the crews. To state the obvious, the less time the customer is out of power the more revenue the utility capturesand the higher customer satisfaction.
This can translate into thousands of dollars in savings tothe utility. AMR allows for only one-way communication Meter to the Utility butthe AMI systems allows for the two-way communication between the utilities and the meters. AMR andAMI have same benefits when it comes to getting away from manual reading meters, power outagenotification, and power quality monitoring.
These metering solutions have been the first wave of thecoming Smart Grid technology. Billing the CustomerAs the smart meters come online the natural progression is for the customer to pay via online bill pay,interactive voice response IVR as well as through the mail and customer service reps. Smart metersallow utilities to get readings anywhere from every 24 hours to however often the utility desires toreceive the data.
Just note the more frequent the meter reading the data server receiving the data will beneed to be scaled appropriately. The days of estimating are quickly becoming non-existent. There are approximately 36, customers in Anderson. Telelink also allows the utility to reverse call customers who are indanger of being cut-off. Once the automated system connects with the customers, they are given theoption of paying their bill via credit card to avoid being cut-off the next day.
Telelink takes pressure offof the utility billing office and the customer service reps through providing information to thecustomers, arranging financing, taking payments, routing phone calls to different departments, andmany more functions.
