Hydro-Québec faces $40M court fight with Massachusetts utilities over winter power cuts

Hydro-Québec and three Massachusetts utilities (Eversource, National Grid, Unitil) are in a $40M court dispute over power cuts during extreme cold in January. The utilities claim Hydro breached contracts by reducing 'firm' power deliveries, while Hydro argues emergency measures justified the shortfall. Both filed lawsuits on Sept. 8, with Hydro seeking $39.69M in unpaid bills and the utilities seeking to enforce future supply obligations.
