Central Maine Power (CMP) will build a high-voltage transmission line to carry hydroelectricity from Quebec through Maine to Massachusetts.
CMP will develop the project, which will add 1,200 MW of transmission capacity to supply New England.
The company is expected to provide $50 million over 40 years to several programs and initiatives in Massachusetts, as part of a requirement of developing the power line.
One of such initiatives is an energy-assistance program that will benefit low-income electric customers in Massachusetts.
Meanwhile, a controversy is brewing as Maine’s consumer watchdog says the deal raises questions about why Maine isn’t being offered a similar level of assistance.
