A budget signed this week by Massachusetts Gov. Maura Healey clears the way for utilities to recover added costs caused by delays of a project to bring Canadian hydropower to the New England grid. The head of Central Maine Power’s corporate parent Avangrid previously said the cost of the $1 billion project grew to $1.5 billion because of delays and inflation during a prolonged court battle. Legislation included the supplemental budget approved Monday allows transmission service agreements to be renegotiated by utilities. Those costs will ultimately be passed along to Massachusetts ratepayers. Construction on the project resumed in August.
