When you’re reviewing your budget, there’s one business expense you will not see listed as a line item: power quality. For many businesses in Denver and across Colorado, poor power quality is costing far more than they realize. Because it does not trigger an obvious alarm, the problem often builds quietly for months or even years, with no one connecting the symptoms to the actual source.

Power quality issues are different from power outages. The lights stay on, equipment continues running, and everything may appear normal on the surface. Behind the scenes, though, the efficiency, reliability, and lifespan of the electrical systems and equipment in your facility can all be affected. Understanding what power quality is and what it may be costing your business is the first step toward fixing the problem.

What Is Power Quality?

Power quality refers to the consistency and cleanliness of the electrical supply flowing through your facility. In a perfect world, electricity arrives at your equipment as a smooth, stable flow of power at the right voltage and frequency. In reality, however, the power supply is rarely perfect. Instead, it can experience a range of disturbances that can degrade its quality in ways that are invisible to the naked eye but potentially damaging to the equipment drawing from it. 

Some common power quality issues include:

• Voltage sags and swells, brief drops or spikes in voltage
• Harmonics, typically caused by devices such as variable frequency drives, LED lighting systems, and computer equipment that distort the smooth wave of the electrical current 
• Transients, sudden short-duration spikes in voltage that can result from switching operations, lightning strikes, or utility events
• Power factor problems, which reflects how efficiently your facility is using the power it draws

While none of these issues are dramatic in the moment, they do add up over time. 

The Hidden Costs Your Business Is Absorbing

Permanent Equipment Failure

Every piece of electrical equipment in your facility has a lifespan, which refers to how many operating hours it’s built to deliver under normal conditions. However, when voltage fluctuations, harmonic distortion, and transients compound over time, they can shave years off your equipment’s lifespan. Equipment that should last 10 years might only last for seven. This leaves you having to cover replacement costs ahead of schedule.

Increased Energy Consumption

Poor power factor is one of the most direct ways that power quality issues translate into higher utility bills. When your facility draws more current than it actually needs, you end up paying for that energy when it’s not even contributing to your operation. This translates to thousands of dollars in wasted energy costs each year for commercial and industrial facilities with significant electrical loads. 

Unplanned Downtime 

Voltage sags and transients are among the leading causes of unexpected equipment shutdowns, nuisance tripping of breakers, and unexplained resets of programmable controls and computer systems. Each of these events can interrupt operations and cause more work and headache for your staff. Oftentimes, workers assume it’s the equipment itself rather than the power supply. 

Reduced Productivity and Increased Maintenance Costs 

Equipment that is operating under poor power conditions requires more frequent maintenance, runs less efficiently, and is more likely to experience problems that can be difficult to diagnose. This can ultimately lead to maintenance appointments that don’t lead anywhere, along with added labor costs. The challenge is that technicians end up chasing the symptoms your equipment is showing rather than the root cause. 

How to Handle Power Quality Issues 

Since power issues are difficult to notice on your own, how are you supposed to address them in the first place? 

The starting point is measurement. Power quality problems cannot be effectively diagnosed through visual inspection. Rather, they require monitoring equipment and analysis by a qualified electrical engineer who knows what to look for and how to interpret data. A power quality assessment identifies the specific disturbances in your facility, quantifies their impact, and provides a clear roadmap for addressing them.
