## Data quality

- Capacity figures use different conventions: EIA and Talen report 635 MW and 638 MW of net summer capacity, totaling 1,273 MW, while other sources cite approximately 1,370 MW of nominal capacity. The major 2009-2010 capital project was an air-quality-control retrofit, including flue-gas desulfurization, baghouses, mercury controls, and related systems; it was not a generation-capacity expansion or documented repowering. The approximately $400 million figure relates to Exelon's three-plant Maryland portfolio sale to Raven Power. Exelon's SEC filing reports approximately $371 million of net proceeds after purchase-price adjustments; neither figure is a Brandon Shores-only allocation. The RMR payments are operating compensation and expense reimbursements, not project-financing proceeds. No separate Brandon Shores project-financing debt or equity package is identified in the cited records.
