Energy Audits

  As we’re in the middle of August, Northcentral Electric Power Association is working to help reduce energy usage and save our members money on their utility bill.  As a Tennessee Valley Authority distributor, Northcentral Electric Power Association is part of the Tennessee Valley Authority and we’re proud to offer a service that many of our commercial members don’t know about: energy audits.

  This is a FREE service offered to our commercial and industrial members.  We help arrange a visit to your business with a TVA representative. That person will go through your business and see where you are using the most energy and suggest ways to cut down on your bill.  You set an appointment and the representative will meet with you and others in your business.  Whether it’s a large refrigerated storage area or a small shop, Northcentral and TVA want to help you find ways to be more energy efficient.

  For our industrial customers, we offer a variety of services to help you become more energy efficient.  TVA’s Comprehensive Services Program offers power analysis, technical services, energy use, and predictive maintenance.

  For more information on this program and other efficiency topics, please call Michael Bellipanni at (800) 325-8925, or visit

  For power analysis, we look at the following items:

  Power quality – these studies address potential power quality issues which may originate inside or outside of your facility and may adversely affect your operations.

  Power factor – Low power factor indicates electricity is being used inefficiently at your facility, which can result in additional charges on the power bill.  By evaluating your facility’s current and historical power factors, recommendations are provided to reduce or eliminate  charges associated with low power factor.

  Grounding/Bonding/Surge Protection Studies – Studies can be conducted and recommendations made to rectify improperly designed or installed grounding and bonding systems which may result in safety or operational issues. Additionally, surge protection recommendations an be made to reduce the risk of equipment damage which can result from surges such as those caused by nearby lightning strikes.

    Demand-side management – Peak demand costs can be a significant part of a customer’s electric energy costs. Following the gatherings of energy usage date and facility operating schedules, recommendations are then made to assist customers in effectively managing peak demand and the associated costs.

  For technical services, Northcentral Electric Power Association reviews:

  HVAC – Heating, ventilation, and air-conditioning studies examine the sizing and efficiency of HVAC systems, offer heating and cooling system comparisons, investigate potential problems with existing systems, and provide recommendations for improvements.

  Lighting – Lighting studies provide recommendations on the design of lighting systems for facilities such as sports fields, roadways, parking lots, and commercial and industrial facilities with specific consideration given to the area of energy efficiency.

  Wiring and electrical distribution equipment – This service provides an analysis of your facility’s electrical distribution system, including the sizing of wiring and electrical distribution equipment. Recommendations are made if system improvements are needed. This service is also available for current or future facility expansions or modifications.

  Reviewing the problems that may occur is also important to our members, Northcentral Electric Power Association uses the following methods:

  Infrared surveys – Infrared surveys are performed to identify hot spots in electrical equipment such as transformers, switchgear, breakers, control panels, and bus and conductor connections, as well as scans for facility heating and cooling loss.  Identifying these hot spots may result in improved equipment reliability.

  Ultrasonic testing – This service utilizes ultrasound technology to locate and tag compressed air leaks in a facility’s compressed air system.  Repairing these leaks may result in improved air system efficiency and significant energy cost savings.
