Columbus, Neb. – Agriculture is a key component of Nebraska’s economy. With planting season on the horizon, Nebraska Public Power District is encouraging farmers – many involved in spring planting at this time – to be particularly alert to the dangers of working near overhead power lines.
“We want all farm workers to look up, look down, look all around before starting work to see where potential contact between farming equipment and electric transmission and distribution lines could occur,” said NPPD Transmission and Distribution Manager Joel Dagerman.
NPPD urges farm workers to review their activities and work practices that take place around any power lines. Everyone who works on the farm should know the location of power lines and keep farm equipment at least 20 feet away from them. The minimum 20 foot distance is a 360-degree rule – below, to the side and above lines.
“It may take a little more time, but ensuring proper clearance can save lives and reduce the possibility of creating a power outage that impacts more than just the farm. Some can create an outage in a local community,“ said Dagerman. “Contact with power lines can have an adverse effect on an individual through the potential of electrocution, but also affected are homes, businesses and industry through the outage.”
Dagerman urged farmers not to raise or move a power line under any situation and to be aware of underground lines before digging and contact the Digger’s Hotline (dial 811) before work begins.
Many farm electrical accidents that involve power line contact happen when loading or preparing to transport equipment to fields, or while performing maintenance or repairs on farm machinery near power lines. It can be difficult to estimate distance and sometimes a power line is closer than it looks. A spotter or someone with a broader view can help.
Safety tips to avoid contact with power lines include:
The overhead electric wires are not the only electrical contact that can result in a serious incident. Pole guy wires are grounded to the neutral; but, when one of the guy wires is broken, it can cause an electric current disruption. This can make those neutral wires anything but harmless. If a guy wire is struck with farm equipment and breaks, or when making contact with electrical poles and wires, contact the electric utility in the area.
“It is also important for operators of farm equipment to know what to do if the vehicle comes in contact with a power line,” Dagerman explained. “It is always best to stay in the cab and call for help. Warn others who may be nearby to stay away and wait until the electric utility arrives to make sure power to the line is cut off.”
If the power line is energized and the individual steps outside, they become the path and electrocution can be the result. Even if a power line has landed on the ground, there is still the potential for the area nearby to be energized. Remain inside the vehicle unless there is a fire or imminent risk of fire. In that case, the proper action is to jump – not step – with both feet hitting the ground at the same time. Do not allow any part of your body to touch the equipment and the ground at the same time. Continue to shuffle or hop to safety, keeping both feet together as you leave the area.
Once away from the equipment, never attempt to get back on or even touch the equipment. Many electrocutions occur when the operator dismounts and, thinking nothing has happened, tries to get back on the equipment. Alert the local electric utility that have highly-trained lineman that can assist and return a potentially dangerous situation back to normal.
“Taking a few minutes to start each work day to look up, look down, and look all around will be a great step in keeping our Nebraska farm workers safe and avoid the potential for hazards, as well as eliminating disruption of electric service,” Dagerman emphasized.
When are rates set?
NPPD rates are reviewed annually, and any proposed rate changes are normally approved during NPPD’s December Board of Directors Meeting.
Will my bill be higher this month because of the cold weather and rolling outages?
Most NPPD customers can expect to see a higher monthly electricity bill this month due to the recent cold weather event which caused customers to have higher usage. A higher bill would not be the result of a rate increase however because the rates did not change.
Does my NPPD rate change throughout the year?
When proposing a rate change, NPPD typically sets and approves rates during the December Board of Directors Meeting. The rates that are approved go into effect February 1 of the next year.
The only other time NPPD’s rates change during the year is when the higher summer rates automatically go into effect for the months of June through September. Aside from this, any increase or decrease in your bill is likely tied to increased energy usage during severe cold or hot weather.
NPPD retail rates have remained steady with no overall increase in eight years.
How will February’s cold temperatures and rolling outages impact my rates in future years?
The financial impact of the most recent historic polar vortex events as it relates to rates are unclear at the present time. Many factors, including future weather impacts, load growth, and the cost to generate and deliver electricity will impact NPPD’s financial position and rates.
How will cold temperatures and rolling outages impact my monthly bill?
Simply put, if you use more electricity than “normal” you will have a higher bill. Rates have not changed. Think of it as a consistently priced fuel, that never fluctuates in price per gallon. If you need to fill up more often, it will require a larger amount of product, and as a result you have higher costs.
Does it take more energy and cost more to lower my thermostat now, only to raise it later to regain warmth?
This is a myth that many have heard for years. Contrary to belief, your system will operate for longer periods to recover and heat pump systems may switch to supplemental or auxiliary heat, but overall energy use is reduced if the setback occurs over at least a few hours.
NPPD operators at our control center handle increases and decreases in load and train for these situations. The operators refer to this as the Cold Load Effect. When customers are returned to service from a long outage, there can be a sharp increase in electricity usage that must be accounted for. As motors begin to start when the load is energized and more equipment powers on than was previously when the customer was interrupted. This means, when there are several customers experiencing an outage at the same time, operators need to consider the load when the circuit is restored can be higher than when it was interrupted. The longer a circuit is interrupted, the more pronounced the Cold Load Effect will be.
In the case of this most recent event, homes were using heat so consistently during the day and the interruptions were short enough that there was no significant change in electricity usage when one circuit was brought back online and another was turned off. During the rolling blackouts, when one group of customers was experiencing an outage, a new set of customers would betaken offline before the first group was returned to service. This helped ensure that there were no spikes in electricity usage that would have a negative impact on the generation and load balance.
Who can I contact for assistance with payment arrangements for my NPPD bill, or information on assistance agencies?
Payment arrangements can be arranged by contacting NPPD at 1-877-ASK-NPPD.

What is a rolling blackout outage?
Rolling blackouts, also known as rotating outages, are controlled, temporary interruptions of the electrical service directed by the Southwest Power Pool (SPP). These outages can occur when electricity generating resources cannot meet the electricity demand in the region. NPPD and others must reduce demand in an amount directed by SPP and act upon this within minutes.
When is a rolling blackout necessary?
Rolling blackouts are necessary as a last resort to maintain the reliability of the electrical grid system. SPP directs rotating outages when electricity generating resources cannot meet the electrical demand in the region. They rotate or roll to different systems and areas so we can all absorb a short outage at different times versus a long outage for one specific area.
The recent situation was extraordinary and an unprecedented chain of events, including historic low temperatures across the entire SPP footprint, lack of wind generation, reduced amounts of natural gas because of frozen wells and sky rocking natural gas prices. A situation never seen before in this region since SPP was founded.
Why was there little notice before power was shut off to some customers?
Just like many of our retail and wholesale customers, NPPD received the emergency notices from SPP with little warning, requiring us to load shed with just a few minutes to act.
NPPD did our best in this emergent situation to communicate not only to our large industrial and residential retail customers, but also with as many wholesale customers as we could. This was done with a press release, via emails, regularly scheduled wholesale customer meetings throughout the event, and using social media. Unfortunately, with the short timeframe not all customers were able to be reached before some outages began.
We continue to evaluate and review the events of this situation and will look for ways to learn and improve our process, should it ever be needed again.
Is there an easy way to track my energy usage?
Tracking your energy usage can easily be done by downloading NPPD’s mobile application, “NPPD On The Go!”. Download by searching “NPPD” in the Google Play or Apple App store. Then click “Register” and have your account number, service address zip code, and phone number ready. Finally complete the account information.

Who and what is Southwest Power Pool (SPP)?
NPPD is a member of the Southwest Power Pool (SPP), a non-profit regional transmission organization in the central part of the United States. SPP is mandated by the Federal Energy Regulatory Commission to ensure customers in the region receive reliable power, adequate transmission infrastructure and competitively priced electricity. SPP and its members coordinate the flow of electricity across more than 65,000 miles of high-voltage transmission lines spanning 14 states.
Why is it important to have a diverse energy mix?
NPPD believes a diverse generation mix serves our customers best. We use wind -- when it is available. We use coal -- which is reliable and helps keep electric rates low. We use water -- one of the oldest forms of renewable energy. We use nuclear -- which offers emission-free, around-the-clock power. We use natural gas -- to complement the portfolio.
NPPD’s diverse energy generation mix helps keep our electricity reliable and keep rates as low as possible.
Public power, as it always does, answered the call to help protect the bulk electric system which serves the central portion of the country and is part of the larger Eastern Interconnect. The system requires real-time balancing of generation and load. In doing so, we also protected our customers from more detrimental, long-term blackouts.
All of NPPD’s plants were available to SPP during this emergency event. They performed as beautifully during the emergency as our NPPD teammates who worked around the clock to manage the safety, health and financial risk for our customers.
