2017 class action against Eversource and Avangrid
A class-action lawsuit accused Eversource and Avangrid of manipulating natural gas pipeline reservations to raise New England electricity prices by 20%. The suit alleged the companies used legacy pipeline contracts to restrict gas supply and inflate costs.
The case highlighted chronic power cost problems in New England and the utilities' central role in them.
It underscored the region's dependence on constrained gas pipelines and imported power, the same vulnerabilities at issue in the Hydro-Québec dispute.
The 2017 suit shows New England's power market has a history of reliability and cost disputes. The Hydro-Québec case is the latest chapter in the region's struggle to secure affordable, reliable electricity.
