A long-running transmission fight is now centered on when customers get paid back
New England governors and utility regulators are pressing the Federal Energy Regulatory Commission to keep a major refund order on track, arguing that consumers should not have to wait longer for relief after years of paying transmission returns that FERC later judged too high. The dispute now centers on roughly $1.5 billion in refunds tied to transmission owners’ return on equity in the region.
In a filing described by Utility Dive, the New England Conference of Public Utilities Commissioners asked FERC to dismiss a request by Eversource and Avangrid to stay the refund order while litigation continues. The regulators’ position is blunt: delaying repayment would prolong harm to households that have already absorbed excessive costs for more than a decade.
The case goes back to 2011
This fight has unusual staying power. According to the source text, the first complaint over utilities’ transmission return on equity in New England was filed in 2011. Since then, the issue has remained in litigation for roughly 15 years, culminating in a March 19 FERC decision that retroactively cut the base return on equity for transmission owners in the region to 9.57% from 10.57%.
That one-percentage-point change sounds narrow, but over a long period and across large transmission asset bases it translates into substantial money. The New England regulators said the utilities overcharged ratepayers by more than $1 billion since the first complaint was filed. The filing also tied the issue to current affordability pressure facing households.
Importantly, the utilities are not accused of misconduct. Utility Dive notes that FERC did not find wrongdoing. Instead, the commission concluded that the previously authorized return had become too high. That distinction matters because the dispute is fundamentally about regulatory calibration, not fraud or abuse.
