Estimated buildout target through 2030
2027. The current operator project page identifies construction underway and expected customer supply in 2027.
Construction is verified; the completion date remains an estimate. The timeline marker represents the published target year/month, not a confirmed opening day.
Published cost and electrical output
Project cost / investmentAbout USD 902 millionCost scopePublished project-specific capital/construction estimateCost source dateSource page undated; checked 2026-10-11Electrical generating capacity645 MW — Current operator page: 645 MW nameplateVerified project stageUnder construction
Project-specific research
LG&E/KU’s current Mill Creek 5 page states a 645 MW nameplate rating, $902 million cost, construction underway and estimated completion in 2027. Its 2024 groundbreaking release used 640 MW; the current page is used for the primary output rating. EIA’s separate 740 MW figure is retained as inventory context, not extra generating capacity.
Published project-specific cost for Mill Creek 5: USD 9.02e+08. Basis: Published project-specific capital/construction estimate. Published electric generating project rating for Mill Creek 5: 645 MW. Basis: Current operator page: 645 MW nameplate.
LG&E and KU broke ground on Mill Creek 5 on November 13, 2024 and describe a 640 MW natural-gas combined-cycle unit expected in 2027. EIA’s August 2026 construction record independently supports ongoing work. The operator’s 640 MW project rating and EIA generator nameplate rating use different reported figures; retain both labels. November 13, 2024 groundbreaking verifies physical construction.
Scope and evidence
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.

Earlier pin evidence / inventory snapshot
August 2026 inventory status
EIA August 2026 generator inventory, plant ID 1364: Mill Creek (KY), Jefferson County, KY. Included 1 new/recent generating units with a summed nameplate rating of 740 MW.
Generator 5: Natural Gas Fired Combined Cycle; 740 MW nameplate; summer rating 645 MW; (V) Under construction, more than 50 percent complete; planned operation 2027-6.
Date and location
EIA reports operation at month/year precision. The date is the last day of the earliest reported operation month/year, an estimated display boundary, not an exact opening day. Different units may have later dates. Future dates are operator-reported plans, not guarantees.
Coordinates are the EIA-reported plant point, not a verified entrance. New units at existing plants are included; the total excludes older units and battery/pumped storage. Capacity is a power rating, not annual energy output. Status was reported in August and may have changed since.

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.
