Delaware Clean Energy Guide
The First State is pursuing ambitious clean energy goals with a 40% RPS by 2035. Despite its small size, Delaware is advancing solar adoption and positioning itself to benefit from Mid-Atlantic offshore wind development.
Policy Overview
Delaware's Renewable Portfolio Standard requires 40% renewable energy by 2035, with specific carve-outs for solar and offshore wind. The state was an early pioneer in establishing a Green Energy Fund to support clean energy deployment.
Net metering is available for residential and commercial customers, and the state participates in RGGI (Regional Greenhouse Gas Initiative) to cap carbon emissions from power plants.
Active Projects & Development
Distributed Solar Growth
Delaware's solar carve-out is driving residential and commercial solar adoption across the state, supported by favorable net metering and SREC markets.
Offshore Wind Supply Chain
Delaware is positioning its ports and manufacturing capabilities to support Mid-Atlantic offshore wind development, creating potential economic opportunities.

Market Outlook
Delaware's clean energy market will grow as the state works toward its 40% RPS target. Distributed solar remains a focus due to limited land for utility-scale development, while offshore wind presents long-term opportunities.
The state's RGGI participation and climate action plans support continued investment in clean energy and energy efficiency programs.
