- Description: Longview Power Plant is a single-unit, supercritical pulverized-coal facility near Maidsville in Monongalia County, West Virginia, with 807.5 MW of nameplate capacity and 710 MW of summer and winter capacity. Longview Power, LLC operates the plant under Mountain State Energy Holdings, LLC, while the project was originally developed by GenPower Holdings, L.P. and First Reserve. Construction began in January 2007 after a February 2007 financial close, and commercial operation began in December 2011. The plant has remained an operating coal facility while proposed additions have included a separate natural-gas combined-cycle project and utility-scale solar development. On August 1, 2026, AEP announced agreements to acquire the plant and the adjacent gas-project development site from Mountain State Energy Holdings; the price was undisclosed and required regulatory approvals. — Source · confidence: medium

- Quality notes: ["EIA-based records report 807.5 MW of nameplate capacity, while the plant's market-facing and project materials commonly describe the facility as 710 MW; development-era sources also describe the project as 695 net MW.","The February 2007 project-financing announcement reported approximately $1.8 billion of total project cost, later project material reported about $1.82 billion, and a later technical account reported an ultimate total of about $2.1 billion; these are different project-cost estimates rather than separate sale prices.","The 2026 AEP transaction was announced but was subject to federal regulatory approvals as of August 2, 2026; no purchase price was disclosed.","The 1,200 MW gas project and 70 MW solar project were proposed expansion projects, not completed additions to the coal unit.

- Financing summary: The project reached financial close on February 28, 2007, with a $1.1 billion debt package consisting of term loans, a revolving credit facility, and a synthetic letter of credit. GenPower Holdings, L.P. committed the balance of the approximately $1.8 billion construction cost; Goldman Sachs & Co. and WestLB AG New York Branch were the debt underwriters and financial advisers. The project was structured primarily as a merchant plant, with only 300 MW covered by an offtake contract at financial close and the balance sold into PJM. In the 2020 restructuring, approximately $350 million of secured and subordinated debt was extinguished, existing equity was cancelled, senior secured debt holders became the new equity owners, and the new owners funded a $40 million five-year term loan. The 2026 AEP acquisition agreement is separate from project financing: its consideration was undisclosed and the transaction was subject to regulatory approval. — Longview Power Emerges From Bankruptcy · confidence: medium

## Data quality

- EIA-based records report 807.5 MW of nameplate capacity, while the plant's market-facing and project materials commonly describe the facility as 710 MW; development-era sources also describe the project as 695 net MW. The 2026 AEP transaction was announced but was subject to federal regulatory approvals as of August 2, 2026; no purchase price was disclosed. The 1,200 MW gas project and 70 MW solar project were proposed expansion projects, not completed additions to the coal unit. No completed coal retirement or coal-to-gas repowering is identified; the existing unit remained operational as of August 2, 2026.
