Entergy Arkansas says a recently enacted Arkansas law strengthens the case for its plan to build a new natural gas plant, a proposal that has drawn criticism from the state’s attorney general and regulatory staff.
The utility applied to build the 754-MW Jefferson Power Station near Redfield, Ark., in early August, but staff with the Arkansas Public Service Commission and state attorney general’s office asked the PSC in early September to deny the utility’s proposal.
The two agencies cited underdeveloped studies, a neglected analysis of alternatives, uncertain costs and a lack of ratepayer protections (25-047-U). The proposed plant would be adjacent to the utility’s White Bluff coal-fired power station, which is slated for retirement in 2028. Entergy envisions the gas plant would begin operation in 2029.
In a Sept. 19 round of filings, Entergy Arkansas’ rebuttal to state officials invoked acts 373 and 940, both passed by the Arkansas legislature in 2025.
Act 373, also known as the Generating Arkansas Jobs Act, makes it easier for electric utilities to finance new construction projects, while Act 940 adds review for retiring dispatchable generation and emphasizes a reliable, adequate and affordable power supply with the PSC fostering development. Both laws contain emergency clauses.
John Bethel, director of public affairs at Entergy Arkansas, said the Jefferson Power Station is exactly the type of resource the state legislature envisioned and will be “critically important” as the utility’s largest gas plant.
Bethel said the plant is “undoubtedly necessary for [Entergy Arkansas’] long-term ability to provide adequate supplies of reliable, affordable and dispatchable power to all customers.”
In accordance with the two laws, he said, Entergy is prioritizing speed to market for new, dispatchable generation to serve economic development. He added the utility was able to secure in-demand components for the plant “at a time when it is very difficult to procure new gas resources of this kind.”
Entergy hasn’t publicly disclosed the cost of the plant, citing an incomplete engineering, procurement and construction agreement. The utility has redacted total price estimates in public filings.
Entergy also has proposed that the Cypress Solar project — consisting of a 600-MW solar array and a 350-MW battery energy storage system — be paired with the natural gas project. The utility estimates that both projects would add $4.87 to an average residential customer’s monthly bill.
Kandice Fielder, Entergy Arkansas’ senior manager of resource planning, said no one has disputed the utility’s need for the new capacity. She said Entergy’s analyses show that adding the gas plant would “yield substantial net benefits to customers” by using land the utility already owns and White Bluff’s interconnection rights.
Fielder said more than 80% of project costs would originate from two competitive solicitations Entergy Arkansas conducted.
‘Methodological Flaws’
Jeffrey Bower, a consultant with Daymark, in early September filed testimony on behalf of the Arkansas PSC contending that Entergy failed to meet the commission’s resource planning guidelines because it didn’t compare the self-built resource to “market opportunities.” He also said that Entergy didn’t propose any cost containment or consumer protections or compare the new gas plant with a conversion of White Bluff to burn an alternative fuel.
“The attempts by the company to compare the project to alternative options are either inadequate or contain methodological flaws,” Bower said. He noted that Entergy appeared to assume EPA regulations eventually requiring carbon capture technology would be repealed even though they’re not yet dismantled.
Bower asked the PSC to order Entergy to supplement the application with more analysis and protections for ratepayers.
But Bethel said Bower’s stance “must be revisited” given that the legislature has charged the Arkansas PSC with eliminating obstacles to developing a “diverse” generation fleet that includes “cost-effective dispatchable electric generation.”
Bethel also said Entergy may consider converting White Bluff’s coal units into a natural gas peaker plant. However, that conversion would not be enough of a substitute for the Jefferson Power Station. He said ordering a comparison of the coal plant conversion to the new gas plant “is a red herring because the resources are not directly comparable.”
Arkansas Attorney General Tim Griffin similarly opposed Entergy’s proposal. Scott Norwood, an energy consultant who filed testimony on behalf of Griffin’s office, said Entergy hasn’t shown the Jefferson plan would come in at a reasonable cost or “is the best available resource for meeting [Entergy’s] system capacity need in 2030.”
Norwood also said that the utility did not explore the alternative of converting White Bluff from coal to gas, which “would have a far lower cost.” He added that Entergy’s other economic analyses of the plant are “based on unreasonable cost assumptions that serve to overstate the benefits.”
Meanwhile, in its Sept. 22 report, The Dirty Truth, the Sierra Club faulted Entergy for overcommitting to natural gas and backpedaling on sustainability goals.
Entergy in 2019 committed to reducing its emissions by 50% by 2030, followed by a 2021 commitment to 50% carbon-free generating capacity by 2030. However, in late 2024, the utility said its capacity goal would be “delayed for an as-yet undetermined period beyond 2030” and said its emissions timeline could slip based on growing demand. Entergy said it recognized that “some of our new generation resources will be cleaner but not carbon-free.”
The utility said it remains committed to its long-term carbon target of net-zero emissions by 2050.
The PSC has scheduled a public hearing for the Jefferson plant Oct. 30 and expects to issue a final order near the end of January 2026.
