## Data quality

- Capacity figures reflect different dates and measures: GenOn's 2016 filing reported a 597 MW Shawville gas addition, while the current EIA 860M aggregation reports 632 MW of gas-and-oil nameplate capacity. The legal ownership and operating roles are distinct: Shawville Power owns the land and leases it through the Shawville lease structure, while PSEGR and Shawville Lessor GenCo are owner-side entities.
