I signed up for Arcadia to take advantage of their community solar program. I was with them for about 2 years and our rate was the same compared to BGE. Plus they accepted credit card payments which I would use for credit card rewards.

This summer I went all in on solar and got panels to cover my electricity usage. I cancelled Arcadia right after that.

Also you can often call up threatening to cancel and they'll give you bill credits to stay on. I got $75 off one winter month.
