Energy Efficiency for Business

Duke Energy’s energy-efficiency rebate programs are available for both new construction and retrofit projects. With these incentives, you can significantly reduce your upfront projects costs and gain financial leverage to make upgrades to your facility that will save energy and money.

In order to qualify for our incentive programs, you must first complete a Business Energy Check. For new construction projects, a consultation with one of our Energy Advisors is required before installation. 

Incentives are available for the areas of your business’ facility listed below.  Note that measures marked with double asterisks (**) are available for retrofit projects only; new construction is not eligible.

Note: As a result of the new Florida Energy-Efficiency Code, Duke Energy’s program standards for rebates on commercial energy-efficient new construction and retrofit measures will change beginning January 1, 2013. The new construction program changes are a direct result of the higher energy-efficiency building code standards.
