Power Quality
Sophisticated motors, drives and other electrical devices in today’s workplace require a high level of power stability. When dealing with sensitive, high-tech equipment, even the slightest disruption in electrical service can result in costly production delays.

If your operations suffer from unpredictable power disturbances that result in downtime, lost data, equipment damage or other adverse outcomes, we can help.

Our Power Quality service will:


When motors stall, circuit breakers trip, lights flicker or computers lock up, it could be signaling a power quality issue within your facility.

Many power-related operating problems originate from the customer’s side of the meter. Most minor issues can be solved quickly and simply. Others more subtle in nature may require more in-depth analysis. Whatever the case, our community-owned utility is here to assist.

If you are experiencing an energy-related problem, give us a call. We’ll meet with you to gather the facts and discuss your concerns. An energy engineer from our power supplier, WPPI Energy, will use the best technology available to identify the problem. We’ll inspect your facility inside and out, monitor your equipment and conduct readings to help pinpoint the source.

We’ll develop a plan to collect the data needed to improve the electrical performance of your operations. Using sophisticated monitoring equipment, our power quality specialist will analyze the data and discuss various approaches to solving your power quality issue.

In circumstances where you may be experiencing problems as a result of disturbances on our system, we’ll keep you informed as we work to quickly remedy the situation.

When the problem is rooted within your facility, we will assist your staff or electrical contractor in devising a plan to correct the matter. Or, if you need help identifying someone to do the work, we can even provide a list of qualified experts in the area.

Even if you are not currently experiencing power quality problems but would simply like more information on power quality issues for planning purposes, consider giving us a call. We have useful information available at no cost to you, as well as other resources that you may wish to use or purchase.
