West Virginia regulators reject NextEra delay bid on MARL review
State regulators force NextEra's Mountain State project back onto a schedule, adding permitting risk to an already contested regional buildout.
West Virginia regulators on Tuesday (2026-09-08) rejected NextEra Energy's request to pause the review timeline for the Mountain State transmission project, clearing the way for a decision on the contested power line to move ahead on the state's original calendar. The order removes a procedural brake that the developer had sought while it works through right-of-way and cost-allocation disputes with landowners and industrial customers.3
The ruling matters because MARL is one of the largest transmission builds in the PJM footprint, and its schedule now depends on a state commission that has shown little patience for delays in a region where interconnection queues and grid-upgrade costs have become the binding constraint on new generation. A slower review would have pushed cost certainty further out for ratepayers and for developers waiting on transmission capacity to connect projects.6
NextEra had argued that additional time was needed to resolve outstanding issues before the commission ruled. The commission disagreed, and in doing so kept the project inside a window that PJM and state planners have treated as critical for relieving congestion on the western side of the grid operator's territory.6
The decision lands as the broader $249 billion NextEra-Dominion merger, announced Monday (2026-05-18), moves through federal and state scrutiny. That deal would combine NextEra's $195 billion market cap with Dominion's $54 billion valuation and create a regulated utility with roughly 10 million accounts across Florida, Virginia, North Carolina and South Carolina.1
Sen. Angus King, I-Maine, has urged the Federal Energy Regulatory Commission to reject the combination, citing anticompetitive behavior he says NextEra engaged in across New England. King's intervention, made public Tuesday (2026-06-30), adds a political layer to a review already complicated by the sheer scale of the proposed tie-up.3
West Virginia is not in the merger's direct service territory, but the MARL decision shows how state-level regulators are asserting themselves in proceedings that touch NextEra's wider ambitions. The same commission has jurisdiction over cost recovery for the line, and its stance on schedule discipline will shape how the developer finances the build.3
The fight over MARL is part of a larger pattern in which utilities and developers clash with state commissions over who bears the risk of transmission cost overruns. Texas regulators voted 5-0 on Wednesday (2026-06-17) to halt approval of the first of five transmission lines in a buildout that could cost ratepayers at least $33 billion and add more than 3,400 miles of extra-high-voltage lines across the state.2
Todd Staples, president of the Texas Oil and Gas Association, said in a statement Wednesday (2026-06-17) that working with affected parties is fundamental to building out electricity infrastructure, a pointed reminder that opposition from landowners and industry groups has become a standard feature of large-line siting.2
The parallel regulatory paths in Texas and West Virginia point to a shared dynamic: commissions are no longer deferring automatically to developer timelines, even for projects backed by the country's largest power companies. In Ohio, the Power Siting Board has asked a court to punt on a high-stakes solar case after its own delays contributed to a missed interconnection deadline, drawing criticism from developer Open Road Renewables.5
At the federal level, FERC on Thursday (2026-07-02) rejected a waiver request tied to a roughly $2 billion gas-fired project in PJM's fast-track Reliability Resource Initiative interconnection review. The denial signals that the commission is holding projects to the queue's rules even when developers argue the expedited process is unworkable.4
For MARL, the immediate question is whether NextEra can meet the revived schedule or will return to the commission with new grounds for delay. The company's track record in New England, where King and others say its conduct raised consumer costs, gives opponents a narrative hook as the West Virginia proceeding moves toward a merits decision.3
What bears watching is how the commission handles cost allocation if the project's final price tag exceeds early estimates. MARL's sponsors have framed the line as a congestion-relief asset for the whole region, but West Virginia ratepayers will want assurances they are not left holding the bill for benefits that flow east into PJM's load centers. The commission's next order will show whether it shares that concern.6
