Louisville Gas and Electric and Kentucky Utilitieswill offer three new and four expanded energy efficiency programsto ratepayers next year.The programs recently approved by the Public Service Commission include a rebate for new Energy Star appliances, as well as a rebate for customers who recycle their old refrigerators and freezers.LG&E spokeswoman Liz Pratt says the programs are designed give customers ways to better manage the ways they use energy.“The programs are part of our way to help customers use energy more wisely,” she said. “These programs also offset the annual customer energy demand growth, which leads to additional generation.”More efficient uses of energy throughout the state could lead to less energy used, which could reduce the need for new power plants in the future, she says.Other programs include an expanded residential audit service, where the company provides incentives when customers install recommended energy efficiency measures and an expanded effort to match low-income customers with weatherization services.The programs are paid for through surcharges on customers’ bills. The average LG&E electric customer will see the surcharge drop by about 38 cents each month, while LG&E gas and KU customers will see the surcharge increase by about 50 cents.
