How to Maximize the Delaware Incentive Stack
The most effective approach combines the federal ITC with applicable state and utility programs in a single project. Our team models every qualifying incentive for your facility and finances the project under the ESP model for zero upfront cost — meaning the combined incentive value covers the full project cost for qualifying businesses with sufficient federal tax liability.
Key steps: confirm federal ITC eligibility and calculate energy community or domestic content adder eligibility; identify applicable state and utility program applications and deadlines; determine MACRS depreciation benefit based on your entity type and tax rate; and calculate net cash flow under the ESP model before signing any contract.
