Maine power line interruptions spark legal battle between Hydro Quebec, Mass. utilities
Hydro-Quebec and Massachusetts utilities (Eversource, National Grid, Unitil) are in a legal dispute over power line interruptions. Utilities allege Hydro-Quebec breached a 20-year contract, seeking $40M in damages. Hydro-Quebec claims a 'force majeure' event excused its actions and seeks $50M from utilities. The line, aimed at providing clean energy, has faced legal and political challenges.
