Company to close three Illinois power plants in coming years.

Company to close three Illinois power plants in coming years. Peoria Journal Star Updated June 15, 2026, 3:38 a.m. CT A power company plans to shut down three Illinois facilities in the coming years. Vistra Corp. intends to close power plants in Baldwin, Kincaid and Newton, according to notices sent to the state of Illinois. The closures are expected to affect 304 employees, according to the Illinois Department of Commerce and Economic Opportunity. The company cited economic, environmental and regulatory factors as the cause of the plant closures and permanent layoffs. Vistra plans to lay off 83 workers from the Newton plant in October 2027; 99 employees at the Kincaid site in January 2028; and 122 employees in Baldwin in February 2028, according to notices sent to the state May 4 in accordance with the Worker Adjustment and Retraining Notification Act. "Both Baldwin and Kincaid continue to operate today and generate power for Illinois," Vistra spokesperson Jenny Lyon said. "In addition, the Baldwin Solar Facility, which sits on the coal plant property and came online in 2024, will continue operating after the retirement of the Baldwin Power Plant. As we move through the retirement process, Vistra will continue to keep employees and community stakeholders informed of developments and future plans." Vistra is a company with 7,000 employees providing its services across the country, according to its website.

Coal plant conversions support gas demand growth.

Coal plant conversions support gas demand growth. Posted by: East Daley Analytics Despite vocal support from President Trump, the coal industry faces a bleak future as utilities convert older power plants to burn natural gas. East Daley Analytics is tracking nearly a dozen coal-to-gas conversion projects that will support structural demand growth over the next several years. Roughly 7.4 GW of coal plant capacity is slated for conversion to natural gas across the Lower 48. East Daley estimates that, assuming 60-75% combined-cycle utilization, these projects could add 750-930 MMcf/d of incremental gas demand by 2030 (see figure below). Along with the boom in data centers, coal plant conversions are a key factor supporting our forecast for demand growth from the electric sector. In the Macro Supply & Demand Report, East Daley forecasts that gas demand for power generation will increase to 41 Bcf/d by 2030, a 5 Bcf/d gain from average consumption of ~36 Bcf/d in 2025. The conversion projects we're tracking are located near established interstate pipeline corridors, reinforcing the long-term call on existing gas infrastructure as coal use phases down. Some noteworthy coal conversion projects include: * In Arkansas, Entergy's 754-MW Jefferson Power Station will replace the White Bluff coal plant by 2028. The project aligns with growing industrial activity and proposed data centers in the area, and will anchor new baseload demand for the Enable Gas Transmission and Mississippi River Transmission pipelines. * In Texas, Vistra is repowering the Coleto Creek plant in Lavaca County into a 630-MW gas facility while expanding its Permian Basin plant in Ward County. These facilities are within reach of the Natural Gas Pipeline of America (NGPL), El Paso, Northern Natural Gas, Transwestern, and Texas Eastern Transmission (TETCO) pipelines. * In the Southeast, the Tennessee Valley Authority is advancing the 1.4 GW gas project at the Cumberland Fossil Plant in Tennessee, while Georgia Power continues to convert coal units at Plant Yates in Georgia. Both projects are within the Transcontinental Gas Pipe Line (Transco) and Southern Natural system footprints. * In Indiana, AES is repowering the Petersburg Generation Station, while Duke Energy is replacing the Cayuga Generating Station with natural gas turbines. The two projects will add 2 GW of gas-fired capacity. The facilities are near several interstate pipelines, including Midwestern Gas Transmission, TETCO, Texas Gas Transmission, Panhandle Eastern, and Rockies Express. * Western markets show the same shift to gas. TransAlta is converting its Centralia plant in Washington, and PacifiCorp is transitioning the Naughton coal plant in Wyoming to gas. The sites are located near the Northwest Pipeline and Gas Transmission Northwest (GTN) service corridors. These projects are part of a long-term shift away from coal in the power mix. US coal generation capacity peaked at roughly 290 GW in 2011 and has since declined by about 37% to ~184 GW in 2025, according to Energy Information Administration (EIA) data. Over the same period, natural gas has expanded its role in the generation stack, accounting for 43% of utility-scale power generation in 2024. The Trump administration is trying to stem the losses for the coal industry. On Feb. 12, the Environmental Protection Agency (EPA) revoked the "endangerment finding," a 2009 regulation determining that carbon dioxide and other greenhouse gases are a threat to public health. The rule underpins EPA's authority to regulate emissions from facilities like power plants; burning coal is the largest sources of carbon emissions, so the revocation would disproportionately benefit these emitters. The recent EPA ruling follows other efforts by the administration to support coal. In September 2025, the Department of Energy announced $625MM in funds to support the coal sector, including $350MM to recommission or retrofit older coal plants. It's unclear if these measures will halt the sector's decline. Most of the coal plants targeted for shutdown are 40-60 years old and have reached the end of their economic life. While fewer regulations would help at the margin, these coal assets burden utilities with higher operating costs compared to modern combined-cycle plants. Meanwhile, the future is bright for gas. The transition underway will support growing baseload demand from data centers, industrial expansions and economic growth, reinforcing the role of gas in maintaining dispatchable generation. - Kritika Gaikwad.

In The Permian Basin at a Crossroads: Why This Pipeline Boom is Different, East Daley Analytics' latest white paper reveals how gas demand from AI data centers, utilities and LNG exports is rewriting the midstream playbook in the leading US basin.

Vistra boosts dividend to $0.23 amid data center nuclear power debate

Vistra Corp., a nuclear and clean power supplier to data centres, has raised its quarterly dividend to $0.28 per share as of February 2026, ahead of the 20 March ex-dividend date. The announcement coincided with increased scrutiny over the company's ability to scale nuclear capacity whilst managing leverage and legacy fossil fuel assets. The dividend increase and ongoing buybacks have intensified focus on capital allocation, particularly as net income has declined year-on-year. Investors are questioning whether shareholder returns might conflict with funding requirements for nuclear, renewables and storage projects. Analysts project Vistra could reach $24.5 billion in revenue and $3.4 billion in earnings by 2028, requiring 9.8% annual revenue growth. More optimistic forecasts anticipate $28.9 billion revenue by 2028, though recent sentiment shifts highlight differing views on regulatory and balance sheet risks.
