What one campus pays a local government
The parent piece's calculator puts a single large campus at $2M to $90M a year in local revenue, depending on the tax regime and abatements. The reference campus (Project Blue scale: $3.6B of capital, 286 MW) pays about $157M to local governments over 10 years. Permanent jobs run around 50 per facility.
| Tax regime | Reference case | Annual local revenue, low | Annual local revenue, high |
|---|---|---|---|
| Aggressive abatement | Morrow County OR (enterprise zone) | $2M | $3M |
| Partial abatement | Georgia audit representative campus / El Paso Meta | $27.8M | $56M |
| Unabated equipment tax | Virginia-style rates (Loudoun is the ceiling) | $50M | $90M |
