Eversource, Avangrid Ask FERC to Stay $1.5B Refund Decision

Why It Matters

The outcome will determine whether New England utilities must absorb massive retroactive costs, affecting their financial health and the cost of electricity for consumers. It also sets a precedent for FERC’s authority over transmission rate adjustments nationwide.

Key Takeaways

• FERC ordered $1.5B refunds for New England transmission charges.
• Eversource and Avangrid seek stay pending litigation.
• Refunds could strain utilities' liquidity and credit metrics.
• Ratepayers face some of highest U.S. transmission costs.
• Lawmakers may cap extra ROE for ISO‑NE members.

Pulse Analysis

The Federal Energy Regulatory Commission’s recent decision to lower the base return on equity for New England transmission owners has reignited a long‑running debate over rate fairness and regulatory oversight. By reducing the ROE to 9.57%, FERC effectively retroactively lowered transmission rates, compelling utilities to return roughly $1.5 billion to customers for periods stretching back to 2011. This move reflects the agency’s broader effort to align utility earnings with investor expectations while curbing excessive charges that have kept New England’s electricity prices among the nation’s highest.

Utilities such as Eversource and Avangrid argue that the mandated refunds pose an immediate threat to their balance sheets. The sudden cash outflow could erode liquidity, depress credit ratings, and raise the cost of capital needed for essential transmission upgrades and new generation projects. Anticipating litigation, the companies have petitioned FERC for a stay, emphasizing that a premature payout would create “rate whiplash” if later reversed on appeal. Their stance underscores a growing tension between regulatory actions aimed at consumer protection and the financial realities of maintaining a reliable grid.

For ratepayers, the stakes are equally high. New England consumers already pay about $24 per megawatt‑hour in base transmission charges—significantly above neighboring regions. While a refund could offer short‑term relief, prolonged uncertainty may delay further reforms. Lawmakers are watching closely, with some proposing caps on additional ROE for ISO‑NE members to prevent future spikes. The final FERC ruling will not only shape the fiscal health of regional utilities but also set a benchmark for how retroactive rate adjustments are handled across the U.S. power sector.
