Energy Efficiency for Business

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

In order to determine if you qualify for our incentive programs, we highly recommend you have one of our Commercial Energy Assessors come out to your facility to perform a FREE Business Energy Check. Customers who participate may also receive a Commercial Energy Savings Kit.  For new construction projects, a no-cost consultation with one of our Energy Assessors is recommended during the design phase.

Incentives are available for the qualifying measures and equipment listed below. Note that measures marked with double asterisks (**) are available for retrofit projects only.

Energy-Efficiency Improvement Programs for Your Business

Expand All / Collapse All
  • Building Envelope Improvements
    • Ceiling Insulation Upgrade**

      Adding insulation will help you save up to 15 percent on your heating and cooling costs, and incentives of up to 17.5 cents are available for upgrades. If the insulation in your building is R-12 or less, you may be eligible for this incentive program. For more information, download the Ceiling Insulation Upgrade Brochure (PDF).

    • Cool Roof 
      Lower the temperature of your roof and save up to 15 percent on air conditioning costs. Duke Energy incentives of 15 cents per square foot are available for qualifying facilities. For more information, download the Cool Roof Brochure (PDF).
    • Roof Insulation Upgrade

      Increasing your roof’s insulation helps maintain interior building temperatures while saving up to 15 percent on heating and cooling costs. Duke Energy incentives of 7 cents per square foot are available for qualifying facilities. For more information, download the Roof Insulation Upgrade Brochure (PDF).

  • HVAC Equipment
    • High-Efficiency Chillers

      A more efficient chiller can keep your business cooler – and considerably more comfortable – while using less energy. It can also help reduce monthly cooling bills and can even earn incentives of $50 per ton for qualifying equipment. For more information, download the High-Efficiency Chillers Brochure (PDF).

    • Large Unitary AC Units and Heat Pumps (>65,000 Btu/h)

      Installing a high-efficiency unitary AC unit or heat pump can reduce operating costs, reduce annual maintenance and correct equipment reliability issues that may affect facility operation. Duke Energy incentives of $75 per ton are available for qualifying equipment. For more information, download the Large Unitary AC Units and Heat Pumps Brochure (PDF).

    • Packaged Terminal Heat Pumps and Air Conditioners (PTHPs and PTACs)**

      Your HVAC system can be one of the biggest drains on your business’s finances. Save up to 40 percent on cooling and heating costs every year – just by installing a high-efficiency system. Duke Energy incentives of $100 per ton are available for qualifying equipment. For more information, download the Packaged Terminal Heat Pumps and Air Conditioners Brochure (PDF).

    • Small Heat Pumps (<65,000 Btu/h)**

      High-efficiency heat pumps can save on cooling and heating costs depending on the size and efficiency of the unit, and Duke Energy incentives of $200 per unit or $375 per unit are available for qualifying equipment. For more information, download the Small Heat Pumps Brochure (PDF).

  • HVAC System-Related Improvements
    • Chiller Tuneup**

      All existing electric chiller systems could benefit from an annual service. Over time, inefficiencies can naturally occur that could affect your chiller’s performance. Correcting these inefficiencies will help reduce your monthly energy costs. Plus, poorly maintained equipment wears out faster, running up large repair or replacement bills. A one-time Duke Energy incentive of $5 per ton is available for qualifying service. For more information, download the Chiller Tuneup Brochure (PDF).

    • Demand Control Ventilation (DCV)

      Demand Control Ventilation helps maintain an appropriate temperature based on the occupancy of the room and can save on heating and cooling costs. DCV can be installed on existing HVAC systems and may qualify for a Duke Energy incentive of $50 per ton controlled for qualifying equipment. For more information, download the Demand Control Ventilation Brochure (PDF).

    • Duct Check Program**
      Leaky ductwork can lead to inefficiencies within your HVAC system. Duke Energy’s duct program will share the cost of testing your ducts, as well as any necessary repairs if your facility qualifies for additional incentives. For more information, download the Duct Check Program Brochure (PDF).
    • High-Efficiency Energy Recovery Ventilation (ERV)
      An energy recovery ventilation system pre-conditions incoming air, helping to reduce the load on your HVAC system. Duke Energy incentives of $1.40 per CFM are available for qualifying equipment. For more information, download the Energy Recovery Ventilation Brochure (PDF).
    • HVAC Tuneup**
      HVAC systems that receive annual maintenance service perform more efficiently (and last longer). However, inefficiencies can naturally occur that affect your system’s performance over time. You can help reduce monthly energy costs by simply correcting inefficiencies with an annual HVAC tuneup. A one-time Duke Energy incentive of $25 per ton is available for qualifying service. For more information, download the HVAC Tuneup Brochure (PDF).
    • Packaged Terminal Air Conditioner and Heat Pump (PTAC/PTHP) Coil Cleaning**
      PTAC coil cleaning helps your system run more efficiently and can save you up to 25 percent on heating and cooling costs. A one-time Duke Energy incentive of $20 per unit is available for qualifying service. For more information, download the PTAC/PTHP Coil Cleaning Brochure (PDF).
    • Rooftop HVAC Recommissioning**
      Over time, inefficiencies crop up that could affect your building's heating and cooling systems’ performance. Recommissioning your Rooftop Units (RTU) can ensure your equipment is operating at optimal efficiency, saving up to 20 percent on heating and cooling costs. A one-time Duke Energy incentive of $25 per ton is available for qualifying service. For more information, download the Rooftop HVAC Recommissioning Brochure (PDF).
  • Trade Allies/Co-Marketing

    Duke Energy offers Trade Allies a unique promotional partnership to help you spread the word about the benefits of using energy-efficient equipment.
