Data notes (2)
- Capacity factor, 2025 not shown: net generation -174.0 MWh is not positive (the plant consumed at least as much as it produced over the year)
- Heat rate (Btu/kWh), 2025 not shown: fuel burned but net generation is not positive

Can the connection be reused?
A plant that retires usually leaves its substation, transmission connection and interconnection agreement behind, and those may be reusable by a new project at the same site. FERC Order No. 845 lets an interconnection customer use surplus interconnection service at an existing site, and some transmission providers' tariffs let a replacement resource take over a retiring unit's interconnection service, usually within a set time after the retirement. Whether any such right still exists here, who holds it and on what terms depends on the owner, the transmission provider and timing; this page does not establish any of that.
