## Data quality

- Published capacity figures differ by source: the official project page describes a 950-MW maximum design capacity, the U.S. EPA describes a 940-MW facility, and a plant dataset reports 977.4 MW in aggregate. The 950-MW design figure is used in the directory description. No acquisition, sale, predecessor-owner transaction, or sale consideration for the exact Trumbull Energy Center was identified. The February 2024 Macquarie transaction was for the separate Lordstown Energy Center, which began operating in 2018. Commercial-operation timing is reported differently: the project website targeted February 2026, EIA monthly data show a 2026/4 date associated with generator GT12, and Hanwha reported successful commissioning and start-up on June 24, 2026. No expansion, retirement, or repowering milestone was identified.
