The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Documented physical milestone or dated progress/reporting marker. Period-end dates represent only the reported month/quarter; they do not invent an exact operation date. Source estimates are labelled and not treated as confirmed future opening dates.
TVA June 30, 2026 Form 10-Q discloses $276 million spent and up to $155 million additional spending on its 200 MW Allen aeroderivative addition. Sum: up to $431 million, explicitly calculated from published project figures. This is an upper forecast spending envelope, not a quoted fixed-price contract. Allen aeroderivative addition: published generating capacity 200 MW. Operator-reported electric generating capacity; not annual energy production TVA explicitly reports constructing this 200 MW project after a December 2025 air permit. The planning-only Lagoon Creek project is separate and excluded.[1]
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.

Retained only with documented physical construction, commissioning or 2025–2026 opening and published project-specific costs and electrical output. Costs use the published scope and currency; no benchmark estimates or currency conversions. MW is power capacity, not annual electricity production. Expected annual energy, where given, is a forecast. The map point is a reported plant/project location and may be approximate. Matching inventory views and excluded expansion proposals are not additive capacity.
