Should utility companies be permitted to charge customers for interest on costs during regulatory delays?

Eversource has filed a lawsuit in New Britain Superior Court to contest a ruling by the Public Utilities Regulatory Authority (PURA) that reduced its nearly $1 billion storm reimbursement request. The utility is specifically disputing the denial of interest payments and the exclusion of $7.7 million in crew costs.

Why it matters

The company argues that it is entitled to recoup interest on financing costs for storm expenditures incurred between 2018 and 2023. It further contends that regulators utilized faulty methodology when calculating and cutting its claimed operational expenses.

PURA approved more than 90% of the company's $1 billion request while denying $400 million in interest payments. Additionally, the Office of Consumer Counsel had unsuccessfully sought an extra $171 million in cuts to storm expenses.

The players

Eversource

This is a major energy utility provider that supplies electricity and natural gas to millions of customers across Connecticut, Massachusetts, and New Hampshire.

Public Utilities Regulatory Authority (PURA)

This is the Connecticut state regulatory agency responsible for overseeing utility rates, services, and compliance across the state.

Office of Consumer Counsel

This state agency acts as the advocate for Connecticut utility customers in regulatory proceedings, focusing on rate fairness and service quality.

The details

The lawsuit follows a PURA decision that finalized the reimbursement amounts for storm expenses incurred over a five-year period. While the regulator approved the majority of the claims, Eversource seeks to recover interest on the financing costs accrued while waiting for the regulatory review process to conclude.

Timeline

  1. Storm expenses were incurred by the company between 2018 and 2023.

  2. The initial reimbursement request was filed by Eversource in 2023.

  3. PURA reached its official decision on storm costs in July 2026.

  4. Eversource filed its legal appeal on October 15, 2026.

  5. New utility rates are expected to take effect in July 2027.

Market Landscape

This litigation highlights the ongoing tension between utility providers and state regulators regarding the financial risks associated with climate-driven storm infrastructure. It reflects a broader industry trend where utilities and oversight bodies clash over the definition of recoverable financing costs.

The outcome of this legal battle will influence the final cost structure used to set utility rates for Connecticut households. Customers may see adjustments to their monthly bills once the new rates are implemented following the court resolution.

The takeaway

This case underscores the complex financial relationship between essential service providers and public regulators when major weather events disrupt operations. Customers should monitor future rate filings as the litigation process dictates how these infrastructure expenses are ultimately partitioned.

What happens next

Eversource plans to finalize storm costs in preparation for the implementation of new utility rates scheduled to take effect in July 2027.
