Energy Efficiency Investment Fund (EEIF)

Delaware Energy Efficiency Investment Fund Pathways

EEIF offers four primary rebate pathways to Delaware non-residential entities with existing or new buildings tailored to differing needs and resources. All four pathways, and their respective offerings, can be paired with other energy efficiency and renewable energy programs that DCCE administers. 

• Prescriptive Improvement Rebates: Prescribed measures contain technologies where energy savings can be predicted with reasonable accuracy across all applications. The technologies currently eligible for the program include lighting, HVAC & water heating, and appliances & food services equipment. For additional information, see: https://documents.dnrec.delaware.gov/energy/eeif/eeif-program-guidelines-and-operational-procedures.pdf#page=22#page=10
  
• Custom Improvement Rebates: The custom pathway rebate option is designed to encourage non-standard energy efficiency measures, including measures not listed in the prescriptive pathway above, and prescribed measures bundled into a comprehensive full facility upgrade that maximizes energy savings and cost-effectiveness. Projects qualifying under the custom pathway are generally more complex incorporating aggressive measures that permanently raise the efficiency levels beyond that of standard equipment. New construction project energy savings will be determined as the difference between the proposed/installed ECM/system and the current locally adopted energy code baseline parameters.

• Energy Assessment Rebates: For businesses in need of technical assistance to evaluate their facility for cost-effective energy-efficient upgrades, rebates are available to help with the cost of the audit, feasibility study, and project design. Energy assessment rebate support is structured to encourage the identification and installation of identified ECMs. For additional information, see: https://documents.dnrec.delaware.gov/energy/eeif/eeif-program-guidelines-and-operational-procedures.pdf#page=22#page=15
• Combined Heat and Power Rebates: This pathway is designed to encourage the development of CHP in Delaware. Unlike traditional systems that produce electricity and heat separately, CHP, or cogeneration, is the concurrent production of electricity and useful thermal energy from a single source of energy. CHP systems are ideal for businesses with high annual hours of operation and a high thermal load. CHP systems yield increased energy efficiency, reduction in energy operating costs, and improvements in energy resiliency.
