Delaware Sustainable Energy Options
Electricity Plans
Protect your budget with fixed-rate electricity plans. Choose the best electricity plan for your home based on our current Delaware electric supplier rates, services and terms.
Renewable Electric Plans
In Delaware, you can support sustainable efforts and switch to renewable energy. Enter your zip code to find fixed-rate plans that are sourced by 100% national wind and/or solar power for
your home.
I like Constellation because it keeps my electric bill from being too high.
