Leading the Charge

Electric vehicles gaining traction in ND

In 2017, an electric vehicle (EV) charging program became available for the first time to Nodak Electric members. This program is designed to save electric vehicle owners money through a lower electricity rate for battery charging units that are hard-wired and off-peak controlled. Read on for more information.

While it may have seemed futuristic only a few years ago, electric vehicles are beginning to gain traction in North Dakota. Rapid advancements in battery technology now provide drivers with cost-effective vehicles that offer 100 to 300 miles of range per each charge.

The ability to save money is one of the major draws of electric vehicles. Charging with electricity is equivalent to less than $1 per gallon gasoline. If you participate in Nodak Electric’s off-peak charging program, the cost could be less than 65 cents per gallon. Electric vehicles also require significantly less maintenance. There are no oil changes, belts, air filters, spark plugs or other parts that need occasional replacement in a gasoline-powered vehicle.

One big question for many consumers in North Dakota is how electric vehicles perform in cold climates. Both gasoline and electric vehicles have lower efficiencies at colder temperatures. For EVs, cold weather can impact the distance you can travel per charge by 25 to 50 percent. Larger batteries, however, have less performance loss issues. Still, today’s EVs work well in cold climates. It is recommended that you store your EV in a garage during the winter and allow it to heat up while still plugged in. This will improve the battery range.

Nodak Electric members also get the satisfaction of knowing that they are charging with homegrown North Dakota energy. All of the electricity delivered to Nodak is generated by in-state resources, including coal, wind and hydro. By using electricity, you are supporting the cooperative that you own and the economy of your state.

Charging your EV

Charging times vary based on the vehicle and voltage of the charging station. Drivers can charge their electric vehicles through a standard 120-volt outlet, although it takes significantly longer (15-20 hours) than other charging options. Using 240-volt service, a dead battery can be fully charged in approximately two to four hours. Lastly, Direct Current (DC) quick charging is available at some gas stations and along major transportation corridors. On average, the DC charger can add 40 miles of range for every 10 minutes of charging.

Installing a home charger

You’ll charge your electric vehicle at home almost every day. Why not pay less every time you plug in?

The installation of a 240-volt charger qualifies you for a $50 per kilowatt (kW) rebate (maximum $500) and the money-saving off-peak charging rate. The off-peak program allows for the control of certain loads (most commonly heating and water heating) during periods of peak electrical demand. The financial savings realized by controlling loads are distributed back to the consumer through the off-peak electric rate, which is lower than the standard electric rate.

In exchange for the lower rate, electric vehicle charging times are limited to off-peak hours. During October through May, charging can be done from noon to 5 p.m., and from 11 p.m. to 7 a.m. In the summer months, charging is available from midnight to 10 a.m. With only a few hours needed to completely charge an empty battery, most consumers are not inconvenienced by the limited charging times.

Public charging on the rise

Public charging options are increasingly becoming available in North Dakota and Minnesota lakes country. According to www.plugshare.com, a national online charging station locator, there are approximately 18 public charging options in North Dakota, with more planned for 2018. The Detroit Lakes and Bemidji areas also feature multiple public charging stations.

In Nodak’s service area, the new Minnkota Power Cooperative building features a free 240-volt charging station for public use.

Energy services is here to help

If you have questions about electric vehicles or are interested in installing a charging station in your home or business, contact Nodak Electric’s energy services team at 746-4461 or 800-732-4373. They will be able to assist with rebate questions and provide insight into technical requirements.

AMI

Advanced Metering Infrastructure marks 10 years

This year marks the tenth anniversary of a fully commissioned Advanced Metering Infrastructure (AMI) system at Nodak Electric Cooperative. More commonly referred to as Automated Meter Reading (AMR) System, AMI is an integrated system of smart meters, communication networks and data management systems enabling two-way communication between Nodak and its members. What started out as a means to obtain monthly meter readings now plays a vital role in serving the member and Nodak in many ways.

Nodak uses a power line carrier-based solution called Two-Way Automated Communication System, through ACLARA Technologies LLC (TWACS). Commands are sent from Nodak’s office in Grand Forks through the internet and radio systems to various substations within the service area. Substation equipment passes information back and forth with the member’s meter through the power line. The Cooperative’s meters do not use radio frequency to communicate information and only transmit information for up to 20 seconds upon request.

Expecting two years to complete, the first meter was installed in July 2007 and the system fully commissioned in December 2008 after 17 months, and enlisted the help of Nodak’s line workers, technicians, engineers and member and energy services personnel.

Each day, the electric meters are read at or near midnight and three or more additional times for hourly or 15-minute kilowatt-hour (kWh) energy interval data. A meter can also be read real-time when needed, at any given time to check a reading or on a day when service is being transferred. Before AMI, meters were read by Nodak members (self-read), contract meter readers and line workers. Sending an accurate bill was a challenge if meter readings were read on different days each month, not read for extended periods of time or estimated. Invoices sent to members with self-read meters were billed at a 30-day delay causing more confusion. Now, Nodak sends a current bill for one month of usage, which has greatly reduced member confusion and, consequently, call volume and office visits. In addition, Nodak is no longer required to access the member’s property or inconvenience them for monthly meter readings.

Five years ago, a meter data management system (MDMS) was added to store meter data and create reports. MDMS stores hourly or 15-minute energy usage (kWh) values depending on the meter in service. Collection of interval data is important to Nodak for engineering studies, to verify off-peak electric heating systems are shed during control events and in assisting members with usage concerns. Nodak makes MDMS information available to members via SmartHub to track and manage electrical energy usage.

AMI has been a big help during outage restoration. As calls come in from members without power and entered into the outage management system, meters are “pinged” or asked to respond back to verify where power is present in the circuit, directing line workers to begin their work. When a line segment has been repaired and put back into service, meters are pinged again to look for other individual outages. Members can log onto Nodak’s website, www.nodakelectric.com, and click on “Outages” at the top of the page to view areas out of power during extended outages. What AMI cannot do is determine if a member has lost power past the meter, or in the secondary wiring circuit. Since meters cannot report back to the office during a power outage, it is still important for members to call in their outage to Nodak as soon as possible.

The greatest benefit of AMI, from the member perspective has been access to their own meter usage data anytime and anywhere. By logging onto SmartHub through personal computer or mobile device, members can view energy usage data in either hourly or 15-minute intervals (depending on type of meter installed). Members can view daily, weekly or monthly usage to better manage their energy consumption or track performance of energy conservation measures. In addition, current billing period usage can be viewed and compared to past billing periods for members to view how their usage is trending.

Be Fire Prevention Smart

Don’t get burned!

Electricity usually makes life easier by powering kitchen appliances, gadgets and electronics we use for entertainment. However, that same electricity contains the potential to destroy homes and take lives. Electric fires are more destructive than any other type of fire, and they are twice as deadly. Safe Electricity has the following information to help you keep your electric system safe.

  • Consider getting an electric inspection of your home, especially if it is an older home or you have never had an inspection.
  • If an electrical fire starts in your home, do not use water to extinguish it. Water conducts electricity, and you could get an electric shock. Use an extinguisher that is approved for use on electrical fires.
  • Flickering lights, warm, cracked or sparking outlets all indicate electrical problems.
  • If circuits trip, fuses blow or someone gets a shock, your home has an electrical problem. Get an electric inspection.
  • Do not overload outlets, use an extension cord as a permanent wiring solution, or use light bulbs that are not rated for the socket.
  • Contact an electrician about installing an arc fault circuit interrupter (AFCI). An AFCI monitors the flow of electricity in your home. If the flow of electricity is irregular and could cause a fire, the AFCI shuts off electricity.
  • Inspect electrical plugs and cords annually. If they are frayed or cracked, repair or replace them. Do not place cords under rugs, or staple or nail them to the wall.

Phone Scam

Utilities are raising awareness about scams targeting consumers

By Tracy Warren, NRECA

When a scammer called Florida pet clinic operator Cindy Evers last year and demanded immediate payment on an overdue electric bill, it sounded real. “They knew my account number and gave me a figure that I owed that’s close to what I usually pay on my electric bill,” Evers said.

She paid, even though, in the back of her mind, she knew her payment wasn’t late. “I have pets under sedation, and I’m taking care of animals. I think I just panicked, thinking they were going to shut my electricity off. I did what they told me to do.” Evers lost $900 because the call was a scam.

The scam that duped Evers has plagued utility consumers across North America for several years, robbing them of millions. Now, utilities are fighting back. Recently, more than 80 utilities and energy industry organizations from across the U.S. and Canada joined forces to recognize the first-ever North American Utilities United Against Scams Day on Nov. 16, 2016. Electric cooperatives have increased their communication efforts, sending information directly to members and encouraging local TV stations and newspapers to warn citizens about the scam, how it works and what people should do and not do, if they are ever targeted.

Even the wariest consumers can be duped, however. The scammers are developing new tactics every day. The “past due” scam, similar to the one Florida customer Evers experienced, goes something like this: A customer gets a call from an 800 number that looks like a valid utility company phone number. Widely available spoofing software allows crooks to display what appears to be an official number on caller IDs. The caller threatens to cut off power if the customer doesn’t pay.

But here’s the giveaway: The crook will demand payment via a prepaid debit card or money order. And he’ll ask for it within a specified timeframe, often an hour or less. The scammer may even quote an amount that sounds like your typical monthly bill. That way, the threat has even more credibility.

Scammers might direct the customer to a specific store nearby that sells the prepaid cards and instruct the customer to put money on the card and provide the card number to the scammer. Some scammers have even been bold enough to contact potential victims in person, coming to the member’s house.

Here are some tips on how to protect yourself:

  • Do not assume the name and number on your caller ID are legitimate. Caller IDs can be spoofed.
  • Never share your personal information, including date of birth, Social Security number or banking account information.
  • Never wire money to someone you don’t know.
  • Do not click links or call numbers in unexpected emails or texts–especially those asking for your account information. Most utilities will NOT require their customers to purchase prepaid debit cards or money orders to avoid an immediate disconnection.
  • If you receive a call that sounds like it may be a scam, or if you believe the call is a scam, hang up, call the police and report the incident to your local utility. You can alert your family members and friends. Share the scammers’ tactics de- scribed in this article or those you have heard about. You can also help raise awareness and warn others by reposting scam awareness information on social media; use the hashtag #stopscams.

Open Director Position In District 3

Every co-op, whether it’s Nodak Electric Cooperative, your credit union or a farm cooperative, follows the basic principle of democratic member control. Cooperatives are democratic organizations controlled by their members who actively participate in setting policy and making decisions. All these cooperatives work on the same system of one member, one vote. Most often, you are asked to vote and elect individuals who will represent you on the board of directors. These folks are your friends, neighbors and may even be you!

Any member in good standing of the co-op can run for the board. Of our nine board members, three are elected each year at our annual meeting in April, which means with only a few exceptions all members have the opportunity to run for the board each year. This year, we again have three director positions up for election; however, one of our incumbent directors has chosen not to seek reelection. That means we will certainly have at least one new board member when the election is finished. Will it be you?

Being a member of the co-op’s board is an incredibly important position. A director’s decisions will impact issues such as service, rates, work plans and bylaws. These positions hold great responsibility and require men and women who understand our communities’ needs and serve the cooperative members’ best interests.

If you or someone you know are interested in hearing more about how to run for a seat on your cooperative’s board of directors, contact us at the headquarters in Grand Forks and we’ll help you through the process. Even if you choose not to have that level of participation, you should all feel empowered to reach out to current board members and candidates, or encourage your friends and neighbors to participate. When our members are actively involved with the cooperative, we are all better off.

As a cooperative, we invite our members to take an active role. In fact, it is critically important to the survival of the cooperative business model that we use our voices to be heard on the issues that matter to us.

The cooperative business model is a great one – it fosters engagement and creates strong communities. More than 100 years ago, President Theodore Roosevelt recognized this value when he said, “The cooperative is the best plan of organization. Under this plan, every business is governed by a board, every person has one vote and only one vote. Everyone gets profits based on their use of the cooperative. It develops individual responsibility and has a moral, as well as financial value.”

Those words are more true today than ever. Let your voice be heard and take the time to participate in your cooperative’s election and your cooperative’s board of directors.

In closing, I’d like to thank Director Doug Lund for his 28 years of dedicated service to our cooperative. Over his tenure on our board, Doug helped shepherd the merger with Sheyenne Valley Electric Cooperative, represented us on several state and regional boards, and shaped policy that helped Nodak continue to grow. Doug’s contributions will have lasting effects on Nodak in the years to come. We wish him luck in his next adventure, and extend our heartfelt thank you for his service on our board.

Trip Of A Lifetime

By Isaac Joerger
Amazing, fantastic, a tripof a lifetime, are the words that describe the Electric Cooperative Youth Tour. Along the trip, those words were repeated multiple times. After spending six days in our nation’s capital and another half day in

Baltimore, how could words like these not escape from our lips. Everything was very hassle-free throughout the whole tour. The people running the tour have had years of experience and took care of every possible problem before it even happened.

Each day was planned out so we were able to tour as many areas as possible. Some of the sights we visited were the Washington Monument, National World War II Memorial, Lincoln Memorial and the Marine Corps War Memorial. We also visited many museums, including the Newseum, which had many newspaper archives and the current date’s front pages from newspapers around the world. We visited as many Smithsonian museums as time allowed.

During our half day in Baltimore, we visited the National Aquarium and explored the harbor. Even though we spent most of our time on foot, there were times when we could sit back and relax with others from our state. This was a very valuable time because we were able to get to know new teens from our state and form lifelong friendships.

The coolest thing that happened on our trip was how tight we became as a group. At the beginning of the trip, most students were shy and didn’t really know what to say but by the end we were all wondering why we didn’t know each other before.

The trip wasn’t all touring; however, there were two nights when we were able to meet new people from other states while enjoying games, dances and snacks. The trip also featured motivational speakers who did an outstanding job and had amazing life stories. One night a speaker talked to our group about how cooperatives are organized and how they play an important role in our economy.

The Electric Cooperative Youth Tour was the trip of a lifetime for me, and I am extremely thankful that I was chosen for this remarkable opportunity through Nodak Electric Cooperative.

Be Prepared For Winter’s Wrath

Nodak Electric Cooperative strives to provide you with reliable, uninterrupted service every day of the year, but sometimes Mother Nature creates unavoidable power outages. Nodak Electric wants you to remain safe during severe winter weather, so consider preparing now for the possibility of power outages this winter.

Before a power outage

  • Build or restock your emergency preparedness kit, including a flashlight, batteries, cash and first-aid supplies.
  • Make sure you have alternative charging methods for your phone or any device that requires power.
  • If a storm is predicted, charge cellphones and any battery-powered devices beforehand.
  • Know where the manual release lever of your electric garage door opener is located and how to operate it.
  • If you rely on anything that is battery-operated or power dependent like a medical device, determine a backup plan.

To prevent an overload

  • To prevent an overload on the system while power is being restored, take these steps:
  • Turn off every inside light except one.
  • Turn down your thermostat.
  • If the outage lasts more than 60 minutes, turn off your electric water heater.
  • Make sure your kitchen range is off, both the surface and the oven.
  • Turn off all unnecessary appliances and unplug sensitive electronic equipment.
  • When power comes back on, slowly switch your appliances and lights back on and gradually return your thermostat to its normal setting.

During a power outage

  • Only use flashlights for emergency lighting. Candles can cause fires.
  • Keep refrigerator and freezer doors closed. Most food requiring refrigeration can be kept safely in a closed refrigerator for several hours. An unopened refrigerator will keep food cold for about four hours. A full freezer will keep the temperature for about 48 hours.
  • Put on layers of warm clothing if it is cold outside. Never burn charcoal for heating or cooking indoors. Never use your oven as a source of heat. If the power might be out for a prolonged period, plan to go to another location (the home of a relative or friend or a public facility) that has heat to keep warm.
  • Turn off or disconnect appliances and other equipment in case of a momentary power “surge” that can damage computers and other devices. Consider adding surge protectors.

Stay away from downed power lines
Mother Nature isn’t always kind to power lines. Winter winds, snow and ice often prove to be too much for utility poles and power lines. If you see a downed power line or utility pole, contact Nodak Electric immediately.

Do not go near the line or the pole. Just because it’s on the ground doesn’t mean it’s safe to approach.

to report an outage
Because power outages can’t be totally eliminated, Nodak Electric offers these steps to follow if an outage occurs:

  • Confirm the outage. Check your own fuses and circuit breakers first.
  • Check with a neighbor to confirm if he or she is also experiencing an outage before you call the cooperative. This will help your cooperative determine the extent of the outage.
  • Call the cooperative. If the outage is widespread, the phone lines may be busy, but keep trying. Your cooperative will send a line crew to find the problem and restore power as quickly as possible.

If you have additional questions about outages, please call Nodak Electric at 701-746-4461.

Have A Safe And Happy Holiday

At Nodak Electric, safety is the most important job we have. We have the awesome responsibility to do our best to keep each other safe at work and to educate our members on how to stay safe around electricity at home and work. As the holidays draw near, for many of us that means celebrations with friends and family, travel, decorations, cooking and shopping. All of us at Nodak Electric want you to be safe during the holidays, so here are a few tips to consider as you gear up for the season. We can’t guarantee that the hustle and bustle of the season won’t leave you with a few frayed nerves, but hopefully these reminders will help you avoid frayed wires.

Inspect your seasonal items
Many of us have treasured holiday mementos that we bring out of storage year after year. The holidays are also a time when we dust off specialized cooking gadgets that allow us to prepare our favorite seasonal treats. These items are often handed down through generations and might lack modern safety features.

Take a few moments to carefully inspect all your holiday items to ensure everything is in safe working order. A few things to look out for include:
• Brittle insulation on wires
• Rodent damage to wires
• Worn switches with the potential to short circuit
• Corroded metal parts
• Broken legs, unstable bases and other tip-over hazards

Extension cords are temporary
When you asked your school teacher for an extension on your homework, it was a one-time thing, right? The same holds true for extension cords. They are designed for temporary use and should never be used as a permanent or long-term solution.

Never bypass safety devices
There are reasons why some devices have fuses, some plugs have three prongs instead of two and one prong is wider than the other on two-prong outlets. When those safety features get in the way of your holiday decor plans, you might be tempted to tamper with those features. Don’t do it! If your plugs won’t fit together, that means they’re not designed to work together. Rather than tampering with a safety feature, find a safe solution.

Don’t forget to look up
When working outside with a ladder, be mindful of the location of overhead power lines. Always carry your ladder so that it is parallel to the ground. Before placing your ladder in an upright position, look around to ensure you are a safe distance from any power lines.

Stay away from  your service connection
An overhead wire that brings power from a pole to your house can be dangerous if not respected. You should treat this line the same way you’d treat any other power line on our system. Maintain a safe distance – even if that means a small gap in the perfect outline of lights. If you must perform work close to your service entrance, get the professionals involved so it can be done safely.

Read the fine print
If you take a few minutes to read and understand the limitations of your lights and other electrified holiday decorations, you can save yourself a great deal of work and frustration in the long run. For example, the tag at the end of an extension cord will tell you if it’s rated for outdoor use, whether it will remain flexible in cold temperatures and how much energy it can safely handle. Similarly, holiday lights will tell you how many strings can be safely linked together.

Don’t forget about the kids…and pets
If you have small children, you’ve probably spent a great deal of time making sure every square inch of your home is childproof – every cabinet is locked and every outlet is covered. But sometimes the joy of celebrating the holidays with our little ones makes us a little less vigilant about electrical safety. Make sure your holiday decor receives the same level of safety scrutiny you apply to all of the permanent items in your home. Curious and mischievous pets can present similar challenges. Make sure Fluffy isn’t nibbling on all those extra wires or using your tree as her personal back scratcher or jungle gym.

From all of us at Nodak, we want to wish you a happy, but more importantly a safe holiday season.

Holiday Safety Tips

Homeowners decorate their homes for Christmas earlier and earlier – often before Thanksgiving. If you’re ready to start hanging lights, take safety precautions. Nearly three people per hour are treated in hospital emergency rooms for decorating-related injuries during every holiday season, according to the National Safety Council. Here are five ways to keep yourself safe if you have decorating duty this season.

  1. Inspect last year’s lights before using them again this holiday season. Discard any with frayed or exposed wires, loose connections or broken sockets.
  2. Decorate the tree with kids in mind. Place breakable ornaments and those with metal hooks near the top of the tree, where little ones can’t reach them.
  3. Likewise, some holiday plants, including some varieties of poinsettias, can be harmful to children and pets. Keep them out of your home – or at least out of reach. And keep the number for the Poison Control Center handy: (800) 222-1222.
  4. Use sturdy ladders when decorating outdoors. Indoors, climb stepladders instead of using chairs, which aren’t designed for someone in a standing position.
  5. Don’t hide extension cords under rugs or furniture. They can overheat and catch on fire. And when you take the tree down, unplug extension cords. They’re not designed for permanent use.

Fun Facts About LEDs

  • In 2012, about 49 million LEDs were installed in the United States, saving about $675 million in annual energy costs.
  • Today’s LED bulbs can be six to seven times more energy efficient than conventional incandescent lights and can reduce energy use by more than 80 percent.
  • Good-quality LED bulbs can last more than 25 times longer than traditional light bulbs. If the bulb is burned 24 hours a day, seven days a week, it would last three years.
  • From vehicle brake lights to TVs, LEDs are used for their compact size, ease of maintenance, resistance to breakage and ability to focus light in a single direction.
  • LEDs contain no mercury, and a recent U.S. Department of Energy study determined that LEDs have a much smaller environmental impact than incandescent bulbs.
  • By 2030, LEDs are expected to account for 75 percent of all lighting sales globally.
  • Switching entirely to LED lights over the next 20 years could save $250 billion in U.S. energy costs.
