Am I eligible for a Non-Residential or Non-Profit grant if I am not a Delmarva Power Customer?
Yes for solar hot water and geothermal systems. Non-Residential and Non-Profit entities are eligible for the grant program regardless of utility as long as the facility is located in Delaware. Residential systems are only eligible if they are Delmarva Power Customers.
The total program budget for the DESEU funded solar thermal – geothermal program is $3 Million for FY 18 (July 1, 2017 to June 30, 2018). This budget will be capped for Fiscal Year 2018.
Funds will be allocated to projects on a first come, first serve basis. Verification of your Part 1 application secures grant funding for your project for 1 year from the approval date. After 1 year your grant approval will expire and you will need to re-apply to the program.
No additional funding will be approved for Fiscal Year 2018 once the approved funds have been expended.
The chart below shows the current fund availability. The gold portion represents the funds already allocated through the program (53.5%). The blue portion represents funds for applications with a Part 1 application that has been verified (35.8%). The red portion represents funds that have neither been allocated nor reserved with a Part 1 application (0.7%).
