Mine was just over $300, with the Constellation supplier rate. My bill would have been $100 higher with Eversource as the supplier... This is the highest electricity bill I've ever had. Some of my usage was offset by my solar panels, but I usually run out of banked solar power in late November, so I start getting bills higher than the connection fee in December through February. I can't imagine not having solar with these rates, it's fucking insane.
