A Brighter, Cleaner Delaware – Tapping Renewable Energy Resources

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.

Green Grant Program


The Delaware Energy Office offers rebates for solar installations, wind, geothermal heat pumps and solar water heating systems through its Green Energy Grant Program at www.greengrantdelaware.com


In an effort to increase opportunities for solar and geothermal hot water heating systems in Delaware the grant caps for non-residential systems have been raised to $200,000. These increased caps are being funded by the Sustainable Energy Utility. Click here to learn more.

Solar Renewable Energy Credit (SREC) Programs

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 is sold separately from the electricity and represents the "solar" aspect of the electricity that was produced. The value of an SREC is determined by the market subject to supply and demand constraints. SRECs can be sold to electricity suppliers needing to meet their solar RPS requirement.

The DESEU supports the RPS standard and therefore supports the SREC market with programs.


In 2011, the Delaware legislature amended the solar portion of the state Renewable Portfolio Standard (RPS) to switch the burden of acquiring SRECs away from the power providers to the electric distribution companies in Delaware. This amendment drastically reduced the number of buyer participants, effectively making Delmarva Power, the largest electric distribution utility in Delaware, the de-facto long term buyer for the majority of the DE SREC requirement. In response, Delmarva Power proposed the implementation of an SREC procurement program, called the Annual SREC Procurement Program that provides 20 year contracts to SREC sellers on a competitive basis.

Delmarva, which has selected the DESEU to operate the program, plans to run at least one solicitation each spring in order to fulfill its long-term SREC needs. The solicitation is run as an on-line auction. Facilities that qualify as having been built with either Delaware labor or Delaware manufactured parts may be granted an SREC bonus of 10% for each qualification. For example, a facility that qualifies as having been built with Delaware labor may be granted the equivalent of 10% SREC bonus for every SREC produced. A facility that is certified as having been built with both DE parts and labor is qualified for a 20% bonus for every SREC produced, etc.


lgSREC_Fact_box.jpg This program will provide an upfront payment of $.45/watt ($450/kW) in exchange for the first 20 years of solar renewable energy credits (SRECs) created by the system.

The program is open to all Delaware sited systems less than or equal to 50kw in size, regardless of the customer's electric provider. Systems must have a final interconnection date after August 4, 2014 to be eligible and are eligible regardless of grant recipient status.

Any systems that have a long-term contract for their SRECS, including successful bidders in the Delaware SREC Procurement Program, are not eligible for participation in this program. Additionally, systems that take advantage of this program will not be eligible to participate in future Delaware SREC Procurement Program solicitations.

Applications for the SEU SREC Purchase Program can be made at www.GreenGrantDelaware.com beginning August 4, 2014. Customers can complete the first portion of their application at any time, however the final application and grant disbursement will not occur until the system has been interconnected and obtained a Delaware Public Service Commission Certification Number.

This program is initially funded at $1,500,000 per year and upfront SREC purchases will be made on a first come, first serve basis based on system completion. A countdown amount will be available at GreenGrantDelaware.com to help prospective program participant’s gauge the amount of funding remaining in the program.

Solar Thermal and Geothermal Commercial and Industrial Incentive Program

In states across the country, there is a movement towards focusing more resources on renewable thermal technologies, specifically solar thermal. This is primarily domestic solar water heating for homes, apartments, and businesses.

Designed to incentivize the construction of non-residential solar-thermal and geothermal heating systems, this program provides rebates up to $200,000. The rebates are based on the size of the systems and are generally designed to cover approximately 30% of the total cost of the project.

Renewable Energy Resources

  • Findsolar.com 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.

The Delaware Division of Energy and Climate also provides helpful links to websites.
