Grid
Not in EIA-860Grid fieldsEIA-860 states no grid voltage or transmission owner for this plant: its annual file lists plants with a generator in the report year, so a plant that retired earlier is not in it.Transmission lines within 25 km (10)
Connection points within 25 km (2)
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.
