Winter electricity costs in north central and eastern Connecticut appear to be similar to the rest of the state after rate filings.

Eversource on Friday submitted its proposed standard offer electric rates it plans to charge Connecticut customers beginning Jan. 1.

The electric supply rate changes twice a year. It’s typically higher in the winter than in the summer. This year, compared to last year, Eversource said the winter rate is down by about 24% for standard service customers — the lowest it’s been in a few years.
