Delamarva Rate Hike Public Comment Session September 23rd @ 6:00PM
Join us as we give public comment to the Public Service Commission, urging them to reject additional and previous Delmarva Power's rate hike request and preserve the low income utility rate included in the tariff. We need folks to come out and share stories about how much they oppose further rate hikes that continue to squeeze families when the cost of living is soaring in almost every aspect of our lives!
You can give public comment either in person in Dover or virtually online. Registering here will allow us to send you helpful information to draft your comments and confidently use your voice for change!
Register for more information and let us know if you have any questions!
Here is our one-pager on the rate hike:
2026 End of Session Recap
Another busy year in the Delaware General Assembly for the environment, with some amazing bills that are going to do amazing things for our state, as well as bills that we had to oppose because of the harm they would have caused to our state and communities.

Energy bills are up again, but why? As we did last year, we put out a series of short videos that break down why energy prices are going up, and why they are likely to continue going up in the future unless we drastically correct course and bring more clean power online in Delaware.
We also go over some more misinformation being put out by fossil fuel front groups and misinformed legislators. We also share some information on how Data Centers will raise rates for Delaware Electric Co-op and DEMEC (municipal energy utility) customers, even when data centers are in New Castle County. Check it out below!
Right now, about 50% of our members are not receiving our emails! That is usually because when you unsubscribe from a national Sierra Club (or partner) email, they automatically unsubscribe you from our Chapter emails as well. I know, it's frustrating, to say the least. However, you can easily fix it so you can receive JUST our emails.
