Power Factor Correction
|
Wasted energy capacity, also known as poor power factor, is often overlooked. It can result in higher energy costs, safety problems and, in some cases, additional financial charges. Alliant Energy PowerCure™ Services offers state-of-the-art Power Factor Correction with a predictive maintenance approach that can help you determine the best course of action and save you money. Why it's needed |
|
|
The lower your power factor, the less economically your system operates. Therefore, it takes more capacity and is more expensive to serve a customer with a low power factor. Most electrical rate tariffs (including Alliant Energy's) contain provisions that include a minimum power factor. Customers who fall short of the minimum power factor level receive a power factor charge. Power factor charges may range from $5 to thousands of dollars per month. Other consequences of a low power factor include decreased system capacity and increased system losses. How Alliant energy can helpBenefits of increasing a low power factor include eliminated or reduced power factor charges on utility bills, more efficient operations with increased capacity and reduced amperage draw. A certified power quality engineer from Alliant Energy can perform a thorough on-site investigation to help you pinpoint the source of your power factor problems.

Power Factor Correction success story:
|
|
Nash Finch's warehousing facility in Cedar Rapids recognized a need for technical improvements to correct penalty charges applied to their monthly statements due to poor power factor. Nash Finch took advantage of the Alliant Energy's Power Factor Correction expertise and installed a 500 kVAR-stepped capacitor bank. This energy-saving device restored the company's power factor to 98 percent and provided annual non-energy savings of $12,600 due to the power factor credit. |
