Ameren Files for 2,100 MW Gas Plant in MO – Will M-U Gas Feed It?
Ameren Missouri (a subsidiary of Ameren Corporation) announced yesterday that it has filed an application with the Missouri Public Service Commission (MoPSC) to build the West Alton Energy Center, a 2,100-megawatt (MW) combined-cycle natural gas power plant. The company expects the plant to come online in 2031, pending regulatory approval, and to create more than 1,000 construction jobs plus roughly 45 permanent positions. Ameren will build it right next door to its existing coal-fired Sioux Energy Center in West Alton, Missouri — sitting at the confluence of the Missouri and Mississippi rivers just upriver from St. Louis — so it can reuse the transmission connections and other equipment already on site. Company officials pitched the project as around-the-clock, in-state generation that will “work alongside our other resources” as older plants retire and demand climbs. Translation: Missouri needs power that shows up whether or not the wind blows or the sun shines. Read More “Ameren Files for 2,100 MW Gas Plant in MO – Will M-U Gas Feed It?”
In January, MDN broke the news that Duke Energy was eyeing a 1,360-megawatt (MW) gas-fired power plant on 1,600 acres in Davidson County, North Carolina (see 
There’s terrific news brewing in Grant County, West Virginia — with an asterisk roughly the size of a cooling tower. Word circulated over the weekend that Dominion Energy plans to build a brand-new natural gas-fired power plant at its Mt. Storm complex, the same site where three coal-fired units have been cranking out electrons since 1965. The key detail: the gas plant would run alongside the coal units, not replace them. That’s more power, not swapped power. We like that math. 
Texas Gas Transmission, LLC, a subsidiary of Boardwalk Pipelines, LP, wants to build the Dearborn County Lateral Project — roughly 12 miles of new 20-inch natural gas pipeline that begins at Texas Gas’s existing system in Dearborn County, Indiana, dips south across the Ohio River into Boone County, Kentucky, then hops back over the river into Hamilton County, Ohio. The destination is Vistra Corp.’s Miami Fort Power Plant, a coal-fired station slated for shutdown until someone had the good sense to convert it to natural gas instead. The lateral would move 265,000 dekatherms per day (Dth/d) of firm transportation service. A dekatherm is roughly one thousand cubic feet of gas, so call it about 265 MMcf/d (million cubic feet per day). Texas Gas filed with FERC in late May. Boone County leaders are not thrilled. 
Georgia Power announced yesterday that it will serve a new OpenAI data center project in Effingham County, Georgia — about 45 minutes from Savannah — expected to create thousands of jobs and billions of dollars in local investment. The $20 BILLION OpenAI facility will need roughly 3,200 megawatts (3.2 GW) of power, and OpenAI has agreed, under a 25-year deal, to provide up to 1,000 MW (1 GW) of flexible demand response, allowing Georgia Power to curtail deliveries during peak periods. The utility calls it among the largest single-facility demand response commitments in the U.S. OpenAI will cover full infrastructure and electric service costs with financial assurances, consistent with Georgia PSC rules. And yes! There is a direct connection to the Marcellus/Utica. Get ready; your future ChatGPT queries may be powered by M-U molecules! 
As part of Kinder Morgan’s second-quarter update, the company made an important announcement that (until now) it had not made. Namely, on May 26, 2026, TGP (Tennessee Gas Pipeline) placed in service its approximately $235 million Cumberland Pipeline project. The 30-inch pipeline is a 32-mile lateral originating from TGP’s existing 100 Line in Dickson County, Tennessee, and terminating at Tennessee Valley Authority’s (TVA) new natural gas-fired power plant in Stewart County, Tennessee. Big Green tried its best to block this project along with the gas-fired power plant, but failed. 
In April 2025, Knighthead Capital Management, Homer City Redevelopment (HCR), and Kiewit Power Constructors Co. announced a plan to convert the former Homer City Generating Station, previously the largest coal-fired power plant in Pennsylvania (Indiana County, 50 miles east of Pittsburgh) into a more than 3,200-acre natural gas-powered data center campus, designed to meet the growing demand for artificial intelligence (AI) and high-performance computing (see 
If we had a nickel for every time we’ve read or heard the Democrats claim the Regional Greenhouse Gas Initiative (RGGI), a tax on carbon dioxide emissions for coal- and gas-fired power plants, doesn’t raise electricity rates, we’d be millionaires! Not that it was ever in question that RGGI does raise rates; we now have a smoking gun. Connecticut’s carbon allowance auction prices under RGGI have risen from $3.07 per allowance in 2008 to $35 per allowance in June 2026, a jump of over 900%. Connecticut residents pay the third-highest (or second-highest, depending on the source) electricity rates in the entire country behind only Hawaii and California. Massachusetts, another RGGI member, is right behind Connecticut at fourth-highest. 
A new wrinkle to report in the case of a South Carolina pipeline, the Elba Express Pipeline, and its quest to build an extension to a gas-fired power plant in Colleton County. In June, we told you that Kinder Morgan, the builder, had been forced to sue some 55 (of the 185) landowners along the proposed route to allow simple access to their property for a survey (see 
Diversified Energy and real estate firm Maverick Holdings have secured an option on 100 acres at Letcher County’s Gateway Industrial Park near Jenkins, aiming to use an existing natural gas compressor station to fuel an off-grid, 100-megawatt power plant that could attract data centers or manufacturers. The Appalachian Industrial Development Authority signed an 18-month joint development agreement in March, though some board members were asked to sign NDAs. Local officials remain cautiously optimistic, citing potential tax revenue and infrastructure funding, but stress the project is still in early, unproven stages. 
Despite claims by anti-fossil-fuelers that the Tenaska Westmoreland Generating Station in southwestern PA would spread disease and death if it were built, it’s been up and running since 2018, producing power and generating revenue for both its builders and the community. Oh, and everyone is in good health. However, the plant has been operating under a state permit since it opened. It needs a federal Title V permit for long-term operation. The state Department of Environmental Protection (DEP) issues such a permit. Good news! The DEP recently issued the Title V permit for this power plant. 
In February, FirstEnergy subsidiaries Mon Power and Potomac Edison announced they had selected a 35-acre site in Maidsville (Monongalia County), West Virginia, for a new 1,200-megawatt natural gas power plant (see
