Far more projects are announced than will be built. Beacon reads the state air-permit filings for new gas-fired generation of 10 MW and up, and for the data centers it powers, so you can see what is actually moving through permitting and how much capacity it adds. Texas, Georgia, Louisiana, Ohio, Pennsylvania and Virginia, updated daily.

Could you build this?
Partial The filing dashboard can be vibe-coded, but the value depends on collecting and parsing messy state air-permit filings across many states, which needs domain knowledge and ongoing data curation.
What it would actually take: The stack would be scrapers and parsers for each state environmental agency's permit portals, often PDFs and inconsistent formats, feeding a database with entity matching (plants, data centers, capacity in MW) and a search/alert UI. The hard part is maintaining accurate, complete data across jurisdictions and interpreting permit status and capacity correctly, which requires environmental permitting expertise and continuous data-engineering effort.
