Revenues Lost: GIS Recapturing Lost Revenues for

Utility Companies

Electrical utilities lose profits due to line loss, outage restoration, utility billing, crews not performing

at 100%, wasted fuel, etc. In this ebook we are going to focus on three of the main areas of lost

revenue: Line Loss, Outage Restoration, and Utility Billing. We will also show how a Geographical

Information System (GIS) can help solve these issues.

First let’s define a Geographic Information System (GIS). GIS is organizes many different data sources

into one location. In essence the GIS becomes of the hub of the all the data sources and the output to

the users (the public, employees, and vendors). See Figure 1 below:

Figure 1

You will see this figure again in the chapter on Outage Management and Restoration. Notice how all

the data sources feed into the GIS. All the data is matched up through relational databases then output

to users (in this figure we reference the dispatcher but the GIS also out flows to engineering, meter

department, operations, etc.) inside the utility as well as the customers.

Line loss, outages, and utility billing issues are all sources of lost revenue. There are billions of dollars

lost over the course of a year due to estimated billing, unplanned outages not efficiently restored, and

Page 3: GIS Smart Grid Ebook

just plain electricity loss across the lines as power is distributed from the power plant all the way to the

customer. How do we recapture these revenues? How do we become more efficient in the operations of

the electrical utility of today's informational age? As we push towards the full implementation of the

Smart Grid these are questions which need to be answered. Hopefully you will see how we can use GIS

to solve these issues in the coming chapters.

Line-Loss

Line-Loss is a constant battle for electric utility companies regardless of their size. What once was an acceptable level for line-losses can no longer be acceptable. According to the Department of Energy1, it is estimated that United States utilities lost 6.6% in 1997 and of 6.5% in 2007. In some cases the percentage of line-loss reaches 10% - 15%. This can result in multi-million dollar losses. In a letter to U.S. Department of Energy Secretary Spencer Abraham, National Rural Electric Cooperative Association (NRECA) Chief Executive Officer Glen English had this to say about distribution system line losses:

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. Data from the USDA’s Rural Utilities Service (RUS) show that cooperative distribution system line losses were consistently around 6% from 1994 to 2000, well below the industry norm. In fact, RUS reported cooperative line losses at 4.96% during 2001. While electric cooperatives serve 12% of all electric consumers, they maintain nearly half (2.3 million miles) of the nation’s distribution miles of line. With their consumers widely dispersed (6.6 consumers per mile compared to 34 for investor-owned utilities and 44 for municipals), cooperatives have maintained a high degree of distribution efficiency under very challenging conditions. 2

The U.S. Energy Information Administration (eia) has created a table of the “State Electricity Profiles”. The total for the United States is as follows:

Average Retail Price

Net Summer Capacity

Net Generation Total Retail Sales

(cents/kWh) (megawatts) (megawatthours) (megawatthours)

U.S. Total

Causes

There are numerous issues4 that cause line-loss for utilities including:

Inaccuracy of wholesale metering CT’s & PT’s

No-load losses within the electric system

Inaccuracy of revenue Meters (calibrations, multipliers, defective, age, sizing, etc.)

Energy Thefts

Un-Metered Errors, especially street and security lights

Billing System account set-up errors

Poor power factor

Phase imbalance

Improper primary/secondary conductor size.

Federal Involvement

The federal government began the process of mandating Smart Grid technology with the Bush Administration. The Obama Administration has not missed a beat in their push for Smart Grid technology. On June 13, 2011 the Obama Administration released this press release “Administration Announces Grid Modernization Initiatives to Foster a Clean Energy Economy and Spur Innovation”5. There are 4 primary goals mentioned in this press release:

1. 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 resilience

In an effort to meet these goals the Obama Administration released these public and private-sector initiatives:

$250 million in loans for smart-grid technology deployment as part of the US Department of Agriculture’s Rural Utility Service, which is focused on upgrading the electric grid in rural America.

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.

New commitments by the Department of Energy to focus on improving consumer access to their own energy information, including the development of a crowd-sourced map to track progress, a data-driven competition designed to harness the imagination and enthusiasm of America’s students to encourage home energy efficiency, and new EIA efforts to measure progress.

o Consumers deserve access to their own energy usage information in consumer-friendly

and computer-friendly formats. 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: www.SmartGrid.gov

The formation of a Renewable Energy Rapid Response Team, co-led by the White House Council on Environmental Quality, the Department of the Interior, and the Department of

Page 6: GIS Smart Grid Ebook

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 20096 allocation to Smart Grid issues. The Green Energy initiatives involving Wind and Solar power will play a role in replacing the fossil fuel generation of the past as we move forward in upgrading our transmission grid in the United States. Upgrading the transmission grid is a necessary element that should have been started a long time ago. If the transmission is not upgraded then maximum results cannot be achieved by the smart grid. Possible solutions7 for transmission are High-Voltage Direct Current (HVDC), Flexible AC Transmission Systems (FACTS) devices, Gas-Insulated Substations, Superconductors, Wide Area Monitoring Systems (WAMS), etc. ABB7 wrote a white paper on these solutions listed above. HVDC has 25% lower line-losses compared to the traditional AC transmission lines while having up to 5 times the capacity of AC lines. The superconductors called HTS (high temperature superconducting) carry a line loss of .5% compared to the 5-8% of the traditional conductors.

Distribution Solutions

ABB also listed other paths to improved efficiency. Here are those proposed paths:

Distributed generation/Microgrids

Underground distribution lines

Intelligent grid design (smart grids via automation)

Reduction of overall T&D transformer MVA

Energy storage devices

Three phase design for distribution

Ground wire loss reduction techniques

Higher transmission operating voltages

Voltage optimization through reactive power compensation

Asset replacement schedule optimization

Distribution loss reduction via distribution automation

Power factor improvement

Load management (e.g., smart metering or price-sensitive load control)

Power electronic transformers AMR/AMI systems have been the first to attack the line-loss issue facing the electric utilities. Those utilities who deployed AMR/AMI systems like Aclara’s TWACS metering, have seen an increase in revenues due to more accurate meter billing. Solving these issues first will result in the highest Return on Investment. As the Smart Grid matures, more devices will be brought into the fold for monitoring. Transformers

Page 7: GIS Smart Grid Ebook

are next on the list and are beginning to be tested. They should be ready in the next 5 years for manufacturing and deployment to utilities. Soon to follow are other protective devices with monitoring systems for the distribution conductors.

Data Generated by the Smart Grid

Now 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 the analysis of data, creation of reports, and gathering of data becomes difficult. It is important that the data from the different sources is interoperable with each other. The best way to ensure this interoperability is to require that vendors providing the Smart Grid components be MultiSpeak (www.multispeak.org) compliant. If you have not heard of the MultiSpeak standard here is a description from MultiSpeak’s “About” page8:

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 600 electric cooperatives, investor-owned utilities, municipals, and public power districts in at least 15 different countries.

The MultiSpeak Initiative is a collaboration of the National Rural Electric Cooperative Association (NRECA), leading software vendors supplying the utility market, and utilities. 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. From this foundation the utility can efficiently perform engineering analysis, outage management (which we will discuss in the next chapter), improve customer service, provide pay via phone or online using credit/debit cards, integrate automated vehicle location (AVL), laptops with distribution system, etc. All of these activities create more efficiency in the utility. Utilities are constantly being bombarded with accusations of rising utility rates from their customers. With the reduction of line-loss those rates could come down. In order to reduce line-loss efficiently the data must be organized, presented and analyzed in such a way that issues on the distribution system are solved in a systematic approach. GIS allows this systematic approach to be developed and shows trends and patterns graphically. If there is no GIS then some patterns/trends could or would be missed.

As we move forward with the Smart Grid, the installation and use of GIS is becoming an essential tool that utilities cannot live without. The utilities that see this vision before investing in Smart Grid upgrades that are not interoperable, will have saved not only money but aggravation as well.

Page 8: GIS Smart Grid Ebook

Outage Management

The number one area of lost revenue in electrical utilities are outages, planned or unplanned. Outages

have been a constant in the past and will continue to be a constant into the future. We can manage these

outages more efficiently in the future by utilizing and analyzing the data provided to utilities during the

outage(s) from one location. This location is a GIS (Geographical Information System).

Data Sources

What are the possible data sources for the electrical utility?

Customer Information System (CIS)

Automatic Meter Reading (AMR) or Advance Metering Infrastructure (AMI)

Phone calls from the customers during the outage using an Interactive Voice Recording

(IVR)/Auto Attendant or calling into a Customer Service Representative (CSR)

Maps (Digital or Paper/Mylar) of the electrical facilities.

Automatic Vehicle Location (AVL) or GPS in the vehicles

SCADA

Weather Radar

Figure 1

Notice in Figure 1 the data sources are not connected and have a person next to each source. When data

sources 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.

All utilities have some sort of mapping whether or not the mapping has been converted into a digital

format depends on the utility. All utilities have customer information in some form or another. If the

utility has Smart Metering (AMR/AMI) then they typically have a CIS. We find that most utilities we

Page 9: GIS Smart Grid Ebook

deal with have just the mapping and Smart Metering with a CIS but not much more. These components

are typically not integrated together.

Integration

Integration of data is the key to managing outages efficiently. GIS is the integrator of data sources. For

electrical utilities, it is important to note the how critical having all data sources MultiSpeak

(multispeak.org) compliant and interoperable. I cannot stress enough how important it is to make sure

all the software that is accessed by the GIS to manage not only Outage Management Systems (OMS)

but as well as the Engineering Analysis, Staking, Billing, Smart Metering, etc. If the interoperability is

there from the beginning the marriage of all the data will be seamless in the GIS making the integration

easier and more cost effective for the utility in the integration process.

GIS joins all the data sources together. It truly is the hub. From this hub the decision makers can make

decisions at a high accuracy rate and faster than ever before. The reason for this is because the data is

displayed on a map. So the trends and patterns become very easy to discern on the fly.

Figure 2

Notice in Figure 2 GIS is now the hub of the wheel and the data sources are the spokes. The number of

employees now allocated to managing the data sources has dropped from 7 to 4, saving money and

resources for the utility. Once the GIS becomes the hub creating custom reports for analysis becomes

very straight forward and also reduces man-hours in creating the report because the data is brought

together in one location.

Managing the Outages

Dispatchers for utilities process a tremendous amount of information during an outage event.

Who is out of power

Where are the crews (Tree and Line)

Page 10: GIS Smart Grid Ebook

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 progresses

Without GIS this job can be chaotic at best at the beginning of an outage event. With GIS this job is

very hectic at worst. The GIS allows the dispatcher to remain organized resulting in clear decision

making, not to mention the correct decisions are usually made because of data being organized in the

GIS then being outputted to the dispatcher in a format he/she can easily disseminate very quickly.

See how a GIS makes life easier on the dispatcher by bringing together the data sources shown below:

Figure 3

As you can see in Figure 3, IVR and Web applications help in the communications with customers

improving the service customers receive from the utility. AVL allows the dispatcher to see where the

crews are located at all times to improve safety of the crews. The AMR/AMI and IVR calls also give

the dispatcher an accurate picture of the current state of the outage event allowing him/her to leverage

utility resources to restore the power to the customers in the most efficient manner.

To state the obvious, the less time the customer is out of power the more revenue the utility captures

and the higher customer satisfaction. Another benefit to having a GIS with regards to Outage

restoration is when it comes time to create statistical reports on the outage, man hours can be decreased

as much as 90% - 95% from my experience. This can translate into thousands of dollars in savings to

the utility.

Page 11: GIS Smart Grid Ebook

Utility Billing (Smart Metering)

Smart Metering started with Automatic Meter Reading (AMR) and has now migrated to Advanced

Meter Infrastructure (AMI). AMR allows for only one-way communication (Meter to the Utility) but

the AMI systems allows for the two-way communication between the utilities and the meters. AMR and

AMI have same benefits when it comes to getting away from manual reading meters, power outage

notification, and power quality monitoring. These metering solutions have been the first wave of the

coming Smart Grid technology. They are higher profile and contain highest risk/reward with the

customers. If the Return on Investment (ROI) can be proven at the customer level then the next phases

of the Smart Grid will be easier to sell to the customers, members, and/or stockholders.

Billing the Customer

As 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 meters

allow utilities to get readings anywhere from every 24 hours to however often the utility desires to

receive the data. Just note the more frequent the meter reading the data server receiving the data will be

need to be scaled appropriately. The days of estimating are quickly becoming non-existent.

The City of Anderson Utilities have implemented Aclara’s Star AMR system for both the Water utility

and Electric utility. There are approximately 36,000 customers in Anderson. In conjunction with the

AMR system Anderson utilities installed Milsoft Utility Solution’s Telelink IVR product in September

2010. In the first 12 months since installation of Telelink $3 million in revenue was collected from

customers calling in on the phone. Telelink also allows the utility to reverse call customers who are in

danger of being cut-off. Once the automated system connects with the customers, they are given the

option of paying their bill via credit card to avoid being cut-off the next day. Telelink takes pressure off

of the utility billing office and the customer service reps through providing information to the

customers, arranging financing, taking payments, routing phone calls to different departments, and

many more functions.

Customer Relationship

Utilities must address their relationship with the customers. The installation of smart metering affords

the perfect opportunity for utilities to bridge the great divide between themselves and the customer.

Utilities must address their relationship with the customers. The installation of smart metering affords

the perfect opportunity for utilities to bridge the great divide between themselves and the customer. We

have seen Google (PowerMeter) and Microsoft (Hohm) come up with products to involve the customer

only to give up. Cisco in the last couple of weeks has bailed out of energy management for buildings.

IT companies just do not understand the utility industry well enough to make sense of the intricacies.

The electrical power industry needs to be the driver and developer of the technology Google,

Microsoft, and Cisco are trying to develop. In a world were smart phones are so prevalent customers

need a one stop app on their phones which interfaces with the thermostat and the meter data

simultaneously, allowing the customers to control the energy use in their homes remotely.

Smart meters must also interface with billing systems and the Customer Information System (CIS). To

go a step further it would be ideal for the smart meters to be interoperable with the billing system and

CIS of the utility, allowing for the customer service cost to drop. The Guardian newspaper in the UK

wrote an article explaining how the system works in a house and why it helps the earth.

Page 12: GIS Smart Grid Ebook

Customer involvement at the beginning is essential. If they are not involved in the beginning there is a

threat of a backlash. In the Jan|Feb 2011 issue of Electric Light & Power, Stuart Ravens has this to say

about Pacific Gas & Electric Co. (PG&E) in their smart meter roll out:

PG&E did not plan its customer advocacy program well, which led to many

complaints including the accuracy of meters, fears of overcharging, concerns

regarding data privacy, the security of smart meters and even health concerns about

radio frequency transmitters.

Significant and well-organized protests followed, including calls for a government

moratorium on PG&E's smart meter deployment until the issues were addressed.

To date the utility has spent about $4 per meter on consumer engagement. In more

successful projects, however, customer spend can be as low as $1 to $1.50 per meter.

Education need not be an expensive exercise, just well-targeted, with early and

sensitive implementation and sustained messaging.

This example should warn other markets that utilities must be on the front foot with

consumers when deploying smart meters to prevent a backlash from destroying

potential cash savings.

Social networking can be leveraged by utilities to reach out to customers. Facebook, Twitter, LinkedIn,

Google +, and other virtual communities need to be used by the utilities to offer information on rate

increases, outages, events, give-a-ways, etc. to build trust with their customers. Regardless of the size

of the utility their customers are heavily involved in the social network world. As the trust is built with

the customer the easier it will be for the utility to install the Smart Grid components and request higher

rates if need be to afford those components.

Page 13: GIS Smart Grid Ebook

Communications

The communication pipe line and the security of this pipe line will be crucial in the expansion of the

smart meters in the Smart Grid. We are talking about massive amounts of data flowing from the field to

the data center in near real-time now and in the future. This is data carrying information about our

customers and information which is sensitive in nature as well as vulnerable to cyber attacks. The other

item to consider is the interaction of the Smart Meters to the customers' smart phones or tablets through

applications.

Utilities must improve the two-way communication with the Smart Grid facilities then work on passing

this technology on to their customers. Interoperablity has to be required by the utility as different

software solutions are brought together to solve the two-way communication issue. Multispeak

(multispeak.org) being required is absolutely required to make this interoperablity a reality. We do not

have money anymore to spend for software companies to charge the electric utilities for development

costs to marry software together initially and every time there is an update to the software or Operating

System at the client site.

In the rural electrical utilities there is a need to have both RF (Radio Frequency), FTTH (Fiber To The

Home), and Wireless. See the case study of Pulaski Electric System as laid out in an article in

PowerGrid International Feb 2011:

Pulaski Electric System (PES) is a Tennessee-based electric utility that combined the

reach of radio frequency (RF) technology and the speed of fiber-to-the-home (FTTH) to

a customer base that spans both urban and rural service areas.

Pulaski implemented a FTTH network in 2007 to provide in town residents and

businesses with high-speed Internet access, as well as high-definition video

entertainment and high-quality digital phone service. Extending FTTH to remote

communities and isolated farms, however, was not practical given the low density of

potential subscribers.

For this reason Pulaski selected a system that could operate in both wired and wireless

worlds.

A hybrid approach enables Pulaski to use both its FTTH network and 220 MHz RF for

rapid and reliable two-way data transport. The utility gets more value from FTTH by

using it for triple-play media and as its AMI backbone. Furthermore, it can quickly and

easily bring smart grid functionality to customers on the edges of its service territory via

the wireless network, where customer service costs are highest. This minimizes truck

rolls, removes high-cost reads and ensures that all customers receive the same high level

of service, regardless of location.

The wireless RF network provides rural reach and redundancy for the FTTH network,

which helps ensure a high system reliability level.

Although the system PES chose operates in both Internet protocol and RF environments,

at its core it is a single network. This simplifies integration to other critical applications,

provides a comprehensive coverage solution and facilitates migration from RF to FTTH

as the fiber network is expanded. It also gives PES the freedom to evolve according to

its own business goals and operational priorities

As a result, PES avoids the costs and complexities that would have resulted from

deploying, managing and maintaining two separate AMI networks.

Page 14: GIS Smart Grid Ebook

The hybrid network offers the scalability and capacity that will enable PES to implement

demand response, energy-efficiency programs and in-home displays to whatever degree

is desired without retooling the entire network—or worse still, starting over from

scratch.

Communication to the smart meters is not only crucial for Outage Management but also for analysis of

the current data model of the electrical facilities. Up-to-date readings from the meters allows the

utilities to do current day of or the day after load allocations, voltage drops, fault currents, etc. will rely

on information coming not from the smart meters but also the SCADA systems, and in the future

transformers, reclosers, capacitors, and other elements on the electrical system.

Closing

Geographical Information Systems (GIS) is a powerful tool to have your tool belt. It is the hub of the

data wheel. All the spokes of the different data sources reach out from the GIS hub. GIS is essential to

the organization, analysis, and distribution of the data whether we are speaking of data in the quantity

we are accustomed to now or the amount of data we will be processing in the future.

As you have seen in this book with the 3 issues (Line Loss, Outage Restoration, and Utility Billing),

GIS is an absolute must in order to truly reduce the cost and revenues lost across the board in these

areas. Without GIS there will be some revenues recaptured but at the end of the day to fully maximize

the benefit of the Smart Grid GIS must be implemented and fully functional. By fully functional we

mean there being complete interoperablity between all components of the GIS allowing even flow of

the data from all the data sources. Without this interoperablity efficiency cannot be accomplished.

Providence GIS Solutions is best suited to solve this interoperablity issue which many of the utilities

have not been able to solve completely.

Providence GIS Solutions is here to serve the electrical utilities as well as water and gas in the

implementation and the expansion of their GIS. Each utility is different; each utility has their own

Page 16: GIS Smart Grid Ebook

unique challenges. In these unique challenges Providence GIS Solutions thrive in designing and

implementing GIS tools to move the utility to a more efficient and stream lined operationally.
