Eversource has announced that they have filed with the Massachusetts Department of Public Utilities to have electric bills for eastern Massachusetts lowered.

According to a statement released Wednesday, the average residential customer should see a price cut of about $25, or about 20 percent, if the filing is approved, though charges will vary by region.

Eversource says that the Basic Service price for residential customers changes twice a year, once on Jan. 1 and once on July. 1.

Customers who purchase electricity through aggregate buyers or generators will not see a change in their pricing.
