Avangrid and Shell terminated SouthCoast Wind PPAs with Massachusetts EDCs after inflation, supply chain, and rate pressures rendered original prices uneconomic. $60M termination payment. Project later re-bid into MA Round 4 (won 1,287 MW Sep 2024). Triggered cascade of other MA/CT/RI offshore wind cancellations.
