Renewable Energy Programs

We're lucky to live in a progressive state that recognizes the power of energy efficiency and clean energy sources like solar, wind and geothermal.  Energize Delaware energy efficiency programs are focused on helping Delawareans save money, create jobs and improve the environment. The program also complements the State Energy Office's rebates for solar and other renewable energy sources. Renewable energy is a smart way to reduce your carbon footprint, stabilize electric costs and preserve natural resources.

Solar Renewable Energy Credit (SREC) Auction

In Delaware, the Renewable Portfolio Standard (RPS) requires electricity suppliers to secure a portion of their electricity from solar generators. The SREC program provides a means for Solar Renewable Energy Credits (SRECs) to be created for every 1000 kilowatt watt-hours of solar electricity created. The SREC program runs at least one on-line auction each spring in order to fulfill long-term SREC needs. Learn more about Delaware's SREC Auction.

As of February 28, 2018, the program is closed to new Solar Thermal applications until further notice. The Solar Thermal funding for Fiscal Year 2018 has been allocated to approved or pending applicants. Participating Contractors registered with the Delaware Division of Energy and Climate will be notified via email should additional funding for Solar Thermal be allocated to the program.

Renewable Energy Resources

  • is provided the American Solar Energy Society .  The site serves as a convenient, user-friendly means for homeowners and businesses to learn about incentives and the economics of solar energy and to find qualified professionals who can install and service systems.
  • The Database of State Incentives for Renewables & Efficiency (DSIRE) contains a list of all the solar power incentives. It is a great resource for those who want to find out which solar rebates and credits are available for a solar power install in a given state.
  • Developed by the National Renewable Energy Laboratory, PVWATTS calculates electrical energy produced by a grid-connected photovoltaic (PV) system.
  • RETScreen is a free software tool developed with the contribution of experts from government, industry, and academia. The software can be used worldwide to evaluate the energy production, life-cycle costs, and greenhouse gas emission reductions for various types of energy efficient and renewable energy technologies. The software also includes product, cost, and weather databases.  Best for experienced users.
  • American Wind Energy Association is a national trade association for the wind energy industry which promotes wind power growth through advocacy, communication and education.
