Massachusetts Governor Maura Healey called on the Trump administration to expedite an Enbridge pipeline review in New England, a reversal of the state's longstanding opposition to new fossil fuel infrastructure. South Korea formalized a policy shift, replacing coal with LNG while tightening carbon rules as part of its 2050 neutrality push, though industry criticized uncertainty over technology feasibility. A Senate permitting bill under consideration would accelerate gas buildout serving data centers, according to analysis of the legislation's provisions.

California advanced its nuclear policy on two fronts after Gov. Gavin Newsom signed two nuclear bills into law this week. Senate Bill 925 requires the state to formulate a fusion energy development plan — covering commercialization strategies, a regulatory framework, permitting, and emissions goal alignment — due to the Legislature by Dec. 31, 2029, with the California Energy Commission directed to hire new staff and allocate approximately $3.1 million annually to execute the work. Assembly Bill 2647 separately tasks the Commission with assessing nuclear's role in powering critical infrastructure and evaluating whether new plants could meet rising electricity demand in coming years.

In Japan, a prefecture-level conflict over high-level radioactive waste disposal hardened after Ibaraki Gov. Kazuhiko Oigawa declared he will not approve a preliminary survey — the second stage of the three-tier site-selection process — and ruled out hosting a final disposal facility entirely. The governor argued that Ibaraki has already borne a disproportionate burden through the Tokai No. 2 nuclear plant and called for candidate sites to be sought first in areas without existing nuclear infrastructure. The statement directly followed Hitachiomiya Mayor Sadayuki Suzuki's announcement that his city would accept the literature survey, the first stage of the process, with Suzuki simultaneously submitting a formal document to the industry minister indicating that intent and noting he may seek central government cooperation depending on outcomes of upcoming resident briefings.

In equity markets, nuclear stocks diverged sharply ahead of earnings, with power generators holding up while uranium miners and fuel-cycle names sold off, a split illustrated by the contrasting performance of names including GEV, CEG, VST, and CCJ.

On the regulatory front, the Federal Energy Regulatory Commission rejected TransAlta's Centralia cost-recovery plan, denying reimbursement for expenses incurred after the Trump administration's 202(c) emergency orders compelled the retired Washington state plant to remain available — a facility that has not generated electricity once since those orders began in December 2025, accumulating more than $50 million in costs. Meanwhile, Arizona Public Service moved in the opposite direction, signing a coal supply contract extension with Navajo Transitional Energy Co. that would extend Four Corners Plant operations to 2038, seven years beyond its previously committed 2031 closure date. The U.S. Energy Secretary toured Duke Energy's Roxboro facility and praised coal at Roxboro plant, a visit occurring one week after the EPA rolled back greenhouse gas regulations on power plants; the Department of Energy has granted Duke Energy approximately $62 million this year for upkeep on two coal plants, though the utility still targets full coal exit in North Carolina by 2040.

In asset transactions, PT Adaro Andalan Indonesia completed the $814 million Kestrel Coal divestment to Yancoal Australia, transferring its 47.99% stake in the Queensland Bowen Basin metallurgical coal mine and granting Yancoal 100% ownership; Adaro may receive up to an additional $550 million in contingent payments over five years depending on coking coal price benchmarks. Separately, the Australian government drew criticism over a controversial new coal mine approval, while Glencore secured preliminary regulatory clearance to continue coal mining in Australia's Hunter Valley until 2045, a development highlighted within a broader report showing that major banks — including Bank of America, Barclays, Citibank, Deutsche Bank, and Santander — sustained coal lending after NZBA pledges, with roughly half of the alliance's coal-financing members actually increasing their exposure between 2022 and 2025.

In litigation, a federal judge dismissed a $1 billion Oakland coal terminal suit brought by Insight Terminal Solutions, ruling the Kentucky court lacked proper jurisdiction over the case; the decision leaves open the possibility of an appeal or refiling in California, and the underlying developer OBOT continues to advance plans for the terminal with potential Trump administration funding. In Colorado, the Trapper Mine final closure was marked after 49 years of operation, coinciding with Platte River Power Authority's commissioning of the 257-megawatt Black Hollow Sun solar project near Fort Collins; Colorado also crossed the threshold of generating more than 50% of its electricity from renewables over the prior 12 months for the first time.

In Australia, the 850-megawatt Waratah Super Battery — built on a former coal plant site north of Sydney — reached full commercial operations clearance on September 28 after the Australian Energy Market Operator verified its performance tests, giving New South Wales a 1,680 megawatt-hour grid stabilization asset designed to discharge within milliseconds when transmission lines experience faults. A local documentary is drawing attention to Omaha coal plant dangers and perceived shortcomings by the local public power utility. Residents along Pennsylvania's Tioga River continue efforts to remediate waterways affected by decades of coal mining damage, with the goal of restoring cold-water fish species and developing a recreation economy.
