Legend Power Station — estimated target 2028
Estimated operation/completion target: 2028. 754 MW generating capacity; About USD 1.6 billion published project cost. Under construction.
Estimated buildout target through 2030
2028. Entergy’s April 2026 groundbreaking release identifies Legend and Lone Star as physically progressing projects expected to begin serving customers in 2028.[5]
Construction is verified; the completion date remains an estimate. The timeline marker represents the published target year/month, not a confirmed opening day.

Entergy’s September 11, 2025 approval release gives a $1.6 billion investment for Legend, updating the earlier $1.46 billion proposal. The operator’s design rating is 754 MW and physical groundbreaking occurred April 9, 2026. Economic-impact and customer-benefit figures are not the construction budget.[3][4][5]

Published electric generating project rating for Legend Power Station: 754 MW. Basis: Operator-reported electric generating capacity; not annual energy production. The operator identifies Legend as a 754 MW combined-cycle plant.[4]
Entergy’s April 9, 2026 announcement confirms groundbreaking on Legend in Port Arthur and Lone Star near Cleveland. Both were approved by the PUCT in 2025 and are expected to serve customers in 2028. The combined projects exceed 1,200 MW; that combined figure is not the capacity of either plant alone. April 9, 2026 groundbreaking verifies physical construction; target service is 2028.[5]
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.
