The “Essence” of cybersecurity

The online world can be a dangerous neighborhood. News of another huge data theft or malicious computer virus seems to arrive almost weekly. One study found that 740 million online records were hacked last year. Target, the giant retailer, revealed cyber-criminals had stolen information on as many as 70 million of its customers alone.

While it hasn’t received nearly as much publicity, cooperatives and other electric utilities haven’t been immune from this assault. Craig Miller, chief scientist for the National Rural Electric Cooperative Association (NRECA), says there are thousands of probes, big and small, into utility systems. These threats to the security and stability of the nation’s grid are only expected to grow.

But an ambitious effort by the Cooperative Research Network (CRN), the research and development arm of NRECA, and several partners is underway to make sure the systems delivering your power remain safe and secure. It’s called “Essence” and through the project, researchers are developing the next generation of automated cybersecurity for the industry.

That’s particularly important for co-op members and other consumers, who not only count on the power being there when they need it, but also on their electricity provider protecting their privacy. “The success of Essence will improve the protections around their personal information and it will improve the reliability of their power systems,” says Miller.

Miller says most of the attempts to hack into utility systems have been efforts to grab personal data or business information. Consumers obviously want to be sure bank account information, social security numbers or other personal data don’t fall into the hands of identity thieves.

But there have also been more ominous attacks that should concern any U.S. citizen. “There have been attempts on control systems. They are much rarer because they require a much higher level of expertise, and there’s no potential monetary gain,” Miller says. “But people have done it.”

The assumption, he says, is that some of these efforts are by “state actors,” other nations probing for potential weaknesses. Defense analysts also believe a cyber-attack on the nation’s power grid could be attractive to terrorists for its potential to create widespread chaos.

The essence of Essence is to protect Americans from all these threats. There are existing software programs with the same goal, but it’s how Essence safeguards utility systems that makes it a major advance in cybersecurity.

Most computer systems are protected through firewalls, special software that blocks suspicious attempts to connect or upload software. But these programs largely depend on lists of known threats that have to be constantly updated. “One of the challenges is that these security systems require expert users who are hyper-diligent about staying current,” says Miller. “They also have the potential for human error. This creates vulnerabilities.”

But Essence changes the balance of power in this constant battle. “Instead of monitoring what’s going in and out of the network, it monitors the network itself and uses advanced algorithms (procedures) to determine what is normal,” explains Maurice Martin, CRN’s project manager for cyber security. “Essence looks for anomalies – stuff that shouldn’t be happening – and then raises a red flag when it sees something that’s amiss.”

This means Essence doesn’t have to depend on lists of the latest dangers out there, or on humans keeping it up-to-date. It doesn’t need to know exactly what hackers are up to because anything that’s not right with the system will get its attention.

All this is accomplished by an unassuming device, small enough to be held in one hand, which can be added to a utility system in key spots to unobtrusively monitor what’s happening on the network.

Project managers also have taken several steps, including using storage in the cloud and open software standards, to keep costs down and make sure Essence doesn’t require extensive expertise to manage. “It’s going to bring state-of-the-art cybersecurity to co-ops of every size, from the biggest to the smallest,” says Martin. “The philosophy is no co-op left behind. Everyone will be able to use this.”

Essence is being developed through a $4 million grant awarded by the U.S. Department of Energy to research next-generation cybersecurity devices. CRN has partnered with Carnegie Mellon University, the Pacific Northwest National Laboratory, and the cyber security firm Cigital on the project. Several large corporations are also following the effort.

Researchers hope to have the first version of the Essence device in the field for tests early next year. If it’s as successful as expected, commercial partners will be brought in to produce the product, providing electric utilities with an affordable, automated cybersecurity system they can depend on.

That will be good news for consumers everywhere. As Martin notes, “Maintaining cybersecurity for your co-op or utility is a something that matters to anyone who’s on a power line.”

Teach your children well about electrical safety

Electricity is a dynamic power source. We live our lives surrounded by it, but sometimes we forget just how dangerous electricity can be. Many home electrical fires, injuries and electrocutions can be prevented when we understand and practice electrical safety. This is especially true for our youngest co-op members.

Throughout the year, not just in May during National Electrical Safety Month, Tennessee’s electric cooperatives offer many value-added benefits to help teach youngsters about electricity. But as your child’s first and most important teacher, perhaps it’s time to have a talk with your sons and daughters to reinforce those lessons.

Start at an early age, teaching them about the physical dangers associated with electrical components and how to handle electrical plugs, outlets, switches and other devices. Keep in mind, talking to your children about electrical safety should also include fun activities and facts about the basics—what is electricity, the need to respect its power and how to use it efficiently as they study, work and play.

As we all know, kids will be kids. Getting them to show interest in some of these lessons won’t be easy. Just remember that what your children learn from you today can be a lifesaver later when they encounter potential hazards like downed power lines in their path, play hide-and-seek behind those big metal electrical boxes in the neighborhood or are tempted to clamber up a utility pole.

Gather your youngsters around the kitchen table or on the front porch—some of the best teachable moments about electrical safety can happen in and around your home. Look around. There are plenty of opportunities to demonstrate safety that are as close as the electrical outlet on your living room wall. For example, show young children how plugs work, and let them know that even if they are curious about the slits of an electrical outlet, nothing else should be placed inside. Each year about 2,400 children end up in the emergency room after suffering injuries caused by inserting objects—paper clips, pens, screws, nails, forks, hair pins, coins and more—into electrical receptacles. That’s about seven children a day who sustain injuries ranging from electric shock to burns.

But this isn’t the only electrical mishap that impacts youngsters. Our reliance on electronics and gadgets have left both youngsters and their parents at risk when they overcrowd electrical outlets, continue to use frayed wires, place devices near liquids or leave electronics on for long periods of time. Some of the same guidelines co-ops offer to protect adults also help protect children. We should all set good examples for our youngsters.

Supplement your lessons at home with resources galore; including those provided by your local electric co-op. The Electrical Safety Foundational International ( is among the many national organizations offering free kits, videos and interactive online tools that make learning and practicing electrical safety fun for you and your children. And as they grow older, remember to keep teaching them about the power of electricity and how to use it safely.

Grain bins: harvesting safely

As rewarding as it may be, farming is an extremely difficult job—and it ranks among the top 10 most dangerous professions in the United States. For Tennessee’s electric cooperatives, safety is top priority for all—our employees and our members.

Our farmers work hard to get the job done, and sometimes it’s easy to forget all the necessary steps to take when practicing safe operations. Grain bins are siloed spaces built for storing grain and fermented feed known as silage. These bins play an integral role in the efficiency and profitability of farm and ranch operations, and safety regulations should always be considered when working around these structures.

Whether you’re purchasing new grain bins or remodeling areas that contain existing ones, proximity to overhead power lines must be a considered factor.

2014_07_DS_Safety_Grain-Bin-SafetySafe clearance

The National Electrical Safety Code requires an 18-foot minimum vertical clearance from the highest point of the filling port of the grain bin to nearby high-voltage wires and a 55-foot minimum distance from the power line to the grain bin wall. See the chart for further guidelines. Changes to landscaping and drainage work can affect clearance heights of power lines, so remember to check these measurements regularly.

Filling grain bins

High-voltage power lines are not insulated, so it’s important to remember to maintain an adequate high-wire clearance when using a portable auger, conveyor or elevator to fill your grain bin.

Moving equipment near grain bins

When moving equipment, such as a hopper or a scaffold, be aware of nearby power lines. Remember to maintain a 10-foot clearance to ensure safety.
Accidents can happen in a split-second, which is why Tennessee’s electric cooperatives remind you to always use caution when working near power lines. If you are considering a plan for a new grain bin or reconstruction of an existing bin’s site, please contact your local cooperative and let them assist you in maintaining a safe environment for you and your family.

Co-ops take 150 students to DC

A record number of young people from electric cooperative service areas in 43 states — including more than 150 students representing Tennessee co-ops — visited Washington, D.C., in June for the 2014 Washington Youth Tour, spending time with elected officials and taking in the historic, interesting sites of our nation’s capital.

Students were rewarded with spots on the weeklong tour of D.C. for writing winning short stories titled “Electric Cooperatives: Serving Our Members Past, Present and Future” describing how locally owned, member-controlled electric cooperatives continue improving lives in their service areas through special community-building programs as well as reliable and affordable electric service. Multiple teachers were also awarded a spot on the trip to recognize their invaluable support of the youth tour program.

“Youth Tour offers students a great opportunity to develop leadership skills, see our government in action and meet other young people from across the country while touring Washington, D.C., and learning American history,” said Jo Ann Emerson, CEO of the National Rural Electric Cooperative Association (NRECA).

The annual event continues a tradition that began following a speech by then-Sen. Lyndon B. Johnson at the 1957 NRECA Annual Meeting in Chicago. The future president urged electric cooperatives to send their young people to the nation’s capital to remind members of Congress that electric co-ops are more than just poles and wires — they are people.

The Washington Youth Tour is a joint effort of local electric cooperatives, the Tennessee Electric Cooperative Association and NRECA. Each school year, co-ops sponsor a short story contest for high school juniors. Winners are awarded spots on the expense-paid trip to our nation’s capital the following June as part of the Washington Youth Tour. This year’s tour ran June 13-19 and included meeting with elected officials, visits to Washington’s popular tourist stops and time to visit with winners representing other co-ops across the state. More than 1,600 youth attended from co-ops nationwide — topping the number of any previous event. Since 1964, more than 53,000 young people have joined the Washington Youth Tour.

“The Youth Tour is one of the most rewarding things I do all year,” said Todd Blocker, TECA’s director of youth and member relations who served as tour director. “These students not only learn about our nation and their electric cooperative, but they also learn leadership skills that will benefit them in college and beyond.”

Students on the tour visited the White House and memorials to past presidents Thomas Jefferson, Abraham Lincoln and Franklin Delano Roosevelt as well as monuments honoring the sacrifices of veterans of World War II and the Vietnam and Korean wars. Strolls through the varied museums of the Smithsonian Institution afforded the students opportunities to learn more about science, history and art. Other fun stops included homes of former presidents — George Washington’s Mount Vernon and Jefferson’s Monticello — a performance of “Disney’s The Lion King” at the Kennedy Center for the Performing Arts and a boat cruise down the Potomac River.

The Youth Tour also included solemn and sobering visits to the United States Holocaust Memorial Museum and to Arlington National Cemetery, where the group laid a wreath at the Tomb of the Unknowns.

No trip to Washington, D.C., would be complete without a lesson or two in government and civics. The group was welcomed to the U.S. Capitol by Sens. Lamar Alexander and Bob Corker, and several representatives also spent some time with their constituents outside the Capitol and posed for photos.

“We are owned by our members, and it is so important that our members understand how that makes us different,” said David Callis. “Our communities and our co-ops need strong leadership, and the Washington Youth Tour is one way we can help prepare students for the roles they may one day fill. The tour and similar educational opportunities made possible by Tennessee’s cooperatives are designed to help students understand what it takes to be a leader in their communities and why leadership is so important.”

Co-ops place near top at TVPPA rodeo

Powerful lessons at 4H Electric Camp

Three hundred rising seventh and eight graders from across the state of Tennessee are exploring the world of energy, electricity and the basic sciences at the 2014 4-H Electric Camp.  While visiting the University of Tennessee, Knoxville campus, 4-H members will discover the world of electricity by participating in various camp learning centers. These learning centers will be taught on Wednesday and Thursday morning, June 25 and June 26, from 8:00 a.m. to 11:55 a.m.  These learning centers provide “hands-on” activities where 4-H’ers “learn by doing.” This year’s learning centers feature:

Electric Lamp – Electric lamps give us light. In this learning center, you will take a lamp kit and some electric insulators and make an electric lamp that will bring light to your room.

Home Energy Conservation – We use electricity to light our home, cook our food, play music, and operate televisions. But as we use more electricity in our homes, our electric bills rise. In this activity, you will learn how conserving electricity in your home not only helps to lower your electric bill but also helps to conserve our environment.

Electric Motors – Motors convert electricity into useful work. You will learn in this activity the different parts of an electric motor and how electromagnetism makes a motor turn. You will also put to use what you have learned by constructing your own electric motor.

Electric Vehicles – Campers will learn about batteries, DC current and how DC current is used to propel electric vehicles. You will also demonstrate your driving skills by maneuvering an electric golf cart through an obstacle course.

Solar Energy Renewable energy resources reduce the use of fossil fuels and negative impacts on our environment.  In this activity, you will learn about how you can use the sun to power things that you use every day.  Join us as you discover all about solar energy.

Electrical Safety Electric power does a tremendous amount of work for us; but, because it is such a powerful force we must be careful around it. This learning center will teach you how to play it safe around high voltage power lines.

The 4-H Electric Camp is a joint venture of The University of Tennessee Extension; Tennessee Electric Cooperative Association and its statewide member cooperatives; Tennessee Municipal Electric Power Association and its statewide municipal power systems; and TVA.


TECA receives National Governors’ Association grant

TDEC and Tennessee Electric Cooperative Association Announce Technical Assistance Opportunity with National Governors Association Center for Best Practices

Project Will Focus on Energy Efficiency Opportunities for Rural Electric Cooperatives

NASHVILLE – Tennessee Department of Environment and Conservation (TDEC) Commissioner Bob Martineau and Tennessee Electric Cooperative Association (TECA) Executive Vice President and General Manager David Callis announce that Tennessee has been selected as one of six states to participate in the National Governors Association Center for Best Practices’ State Policy Retreats on Innovations in Energy Efficiency that aim to reduce energy consumption, stimulate economic demand for local energy-related jobs and services, and lower emissions associated with the generation of electricity in Tennessee.

Under the technical assistance opportunity, TDEC’s Office of Energy Programs and TECA will host an energy efficiency workshop for several of TECA’s members and other State stakeholders to discuss potential financing structures under the U.S. Department of Agriculture’s Energy Efficiency and Conservation Loan Program (EECLP). EECLP currently provides funding to rural electric cooperatives and utilities for the purpose of re-lending to businesses and homeowners for energy efficiency activities such as building weatherization, HVAC upgrades, ground source heat pumps, lighting, small scale renewable generation, consumer education and outreach, and energy audits.  The workshop will address Tennessee-specific challenges to advance energy efficiency programs in rural cooperatives and will develop tools and strategies for designing and deploying successful energy efficiency financing programs to members.

“Tennessee’s electric cooperatives are committed to improving the lives of their members and the communities they serve. We are privileged to be working with TECA to identify ways to access capital for energy efficiency improvements in Tennessee’s rural communities,” said TDEC Commissioner Bob Martineau. “Energy efficiency improvements result in reduced energy demand and consumption, thereby lowering energy costs for consumers.”

“We’re excited about this joint effort and the agencies that are working with us. The cost of heating and cooling a home can be a burden for low-income, rural Tennesseans, so energy efficiency can do more than make homes more comfortable – it can change lives. These improvements can have long-term impacts for homeowners and the communities where they live,” said David Callis, Executive Vice President and General Manager of TECA.

The Tennessee Team will consist of representatives from the Office of Governor Haslam, TDEC, other State agencies, TECA, the USDA Rural Utility Services, Tennessee Valley Authority, Appalachian Voices, and Pathway Lending, a community development financial institution.

Study Rejects Sale of Tennessee Valley Authority

An Obama administration proposal to sell the Tennessee Valley Authority would be a bad business deal that could bump up electricity rates by 13 percent, according to a review by a global financial analyst.

Lazard Frères & Co. declared TVA financially sound, saying there is no reason to privatize it, or turn it into a regional cooperative or state-owned agency.

“TVA’s current strong financial position, ability to self-fund its construction program and anticipated improvements in cost structure, environmental profile and asset mix as a result of long-term initiatives suggest there is no impetus for the federal government to change course,” Lazard said in an analysis released June 4.

Officials at TVA, which supplies power to 155 electric cooperatives and municipal systems, were delighted at the findings and hoped it would end a 15-month dustup about the fate of the nation’s largest public power provider.

“TVA’s healthy financial profile and ongoing efficiency initiatives are expected to generate benefits for TVA’s stakeholders, and Lazard’s summary observation is that there currently is no apparent detriment to ongoing federal ownership at this time,” the authority said in a statement.

Following a suggestion in the administration’s fiscal 2014 budget that it might put TVA on the block, the authority brought in Lazard to go through its financial records for federal budget makers.

The fiscal 2015 budget released earlier this year didn’t include a direct sale provision. But it reiterated that the administration was open to reducing or ending the federal role agency by transferring ownership to state or local stakeholders.

However, Lazard said spinning off the 81-year-old agency wouldn’t reduce the federal budget deficit, because it receives no current appropriations.

In fact, TVA is on track to pay down its debt to $20.8 billion by 2023, which might actually help the federal budget, Lazard said.

Also, TVA’s customers would have to pay for any change in status, Lazard said. That would mean a jump in retail rates of as much as 13 percent from the current 8.7 cents per kilowatt-hour.

“The Federal Government appears likely to realize minimal, if any, value in a divestiture without a significant value transfer from ratepayers in the form of higher rates,” the adviser said.

Tennessee among states hardest hit by EPA regulations

Tennessee’s electric cooperatives call for consumers to take action.

NASHVILLE – Tennessee’s electric cooperatives express concern following the release of the U.S. Environmental Protection Agency’s proposed guidelines that will limit emissions from thousands of existing power plants, including 11 coal plants operated by the Tennessee Valley Authority.

“Estimates indicate that Tennessee will be among the hardest hit by the state requirements, calling for a 38 percent reduction in carbon dioxide emissions by 2030,” says David Callis, executive vice president and general manager of the Tennessee Electric Cooperative Association. “These regulations will hurt Tennessee families, and we are just beginning to understand how severe the impacts will be.”

Tennessee has already taken significant steps to improve energy efficiency and reduce carbon emissions. “The average monthly residential energy use in Tennessee has fallen 16 percent since 2010, and TVA has reduced its carbon emissions by 30 percent since 2005,” says Callis.

“It is important that we make our voices heard. Affordable energy and a strong Tennessee economy depend on an all-of-the-above approach to energy generation.”

The EPA will hold a 120-day public comment period, and you can submit your comments to the EPA by visiting

“The economic challenges faced by many cooperative members make it critical that EPA regulatory programs be cost effective and provide environmental benefits that exceed the implementation and compliance costs,” says Callis.

ACSI scores put Tennessee co-ops among nation’s top

When it comes to customer satisfaction, Tennessee’s electric cooperatives outperform other utilities, according to the American Customer Satisfaction Index (ACSI). Based on 2013 ACSI benchmark findings, Tennessee’s electric co-ops’ satisfaction rating of 82 on a 100 point scale is significantly better than the energy utilities national average of 76. Tennessee cooperatives are even further ahead when compared with investor-owned and municipal utilities, whose customer satisfaction scores were 75 and 76 respectively.

More than 1,000 co-op members from 15 co-ops across the state were interviewed as a part of a regional member satisfaction research project conducted by the Tennessee Electric Cooperative Association in 2013. The ACSI reviewed the research findings and assigned the score earlier this year.

“This research helps us understand the needs of our members and identify areas where we are can improve,” says David Callis, executive vice president and general manager of the Tennessee Electric Cooperative Association. “The opinions of our members are important. As member-owned cooperatives, there is no greater measure of our success than our owners satisfaction.”

The Tennessee findings are in line with national trends, with electric co-ops averaging an ACSI of 81. “These scores validate the cooperative difference,” said National Rural Electric Cooperative Association CEO Jo Ann Emerson. “Member-owned, not-for-profit electric cooperatives put members first and these numbers show why this business model has succeeded and why cooperatives continue to thrive even in uncertain economic times,” Emerson said.

The ACSI reaches across industries, allowing Tennessee cooperatives to make comparisons to other home service providers. The co-op group’s 82 ACSI score is significantly higher than Time Warner Cable’s 60, Comcast’s 63, Charter Communication’s 64 and AT&T’s 71.

The American Customer Satisfaction Index is a national economic indicator of customer evaluations of the quality of products and services available to household consumers in the United States. The overall ACSI score factors in scores from more than 225 companies in 47 industries and from government agencies over the previous four quarters. The Index was founded at the University of Michigan’s Ross School of Business and is produced by ACSI LLC. ACSI can be found on the Web at
