Learn about ESO and Energy Audits

November 3, 2026

From understanding your home's energy use to finding ways to lower your monthly utility bill, CWLP's Energy Services Office (ESO) is here to help customers make informed decisions about energy and water efficiency.

The ESO is a division of CWLP dedicated to helping residential and commercial customers improve personal comfort and convenience while reducing energy and water costs. The office is staffed by energy experts who stay up to date on the latest energy-related technologies and share their knowledge. Whether you want to find ways to improve a property's efficiency, figure out how much electricity your appliances use, have interest in water conservation or learning about available rebates, ESO offers a variety of resources to help you become a smarter energy  and water consumer.

Resources to Help You Save

CWLP's Energy Services Office provides information and guidance to help customers use energy more efficiently and wisely. Customers can turn to ESO for bill and energy usage analysis, conservation tips, home energy audits and information about energy-saving improvements.

Have questions about how much insulation your home needs? Wondering what the ENERGY STAR® label means or how concepts like internal heat gain and convection affect your home's energy use? ESO can help answer those questions and more.

From do-it-yourself energy-saving projects to understanding appliance electricity usage, the office provides practical information to help customers identify opportunities to save energy and water.

Take Advantage of CWLP's Efficiency Rebates

One way ESO helps customers save is through CWLP's energy and water efficiency rebate programs. These programs are designed to help customers get the greatest possible benefit from every dollar they spend on electricity and water while encouraging more efficient homes and businesses.

Current rebate programs include:
  • Air Source and Geothermal Heat Pump Rebate
  • Helping Hands Program
  • High Efficiency Air Conditioner Rebate
  • High Efficiency Toilet Rebate
  • Rain Barrel Rebate
  • Showerhead Exchange
  • Electric Water Heater Rebate
Customers interested in learning more about available rebates, eligibility requirements or program details can contact the Energy Services Office at 217.789.2070 or email nrgxprts@cwlp.com.

Discover Savings Through a Money-Back Home Energy Audit

For residential electric customers, CWLP's Money-Back Home Energy Audit is another valuable resource for identifying ways to improve energy efficiency and reduce utility costs.

The audit, which includes a blower door test, helps identify sources of unwanted heat loss and heat gain throughout the home. Energy experts then use that information to provide recommendations for improvements and help homeowners determine which solutions may be the most cost-effective.
