How This Is Scored
The HD Market Scorecard is Hyperscape Digital's own weekly assessment of how hospitable each major US market is to new large-load interconnection — an opinion index built from public data and our on-the-ground read, not a third-party rating. Grades run A through F on the weighted factors below.
| Factor | Weight | Sources |
|---|---|---|
| Interconnection queue wait / time-to-power | 35% | LBNL Queued Up, ISO queue data |
| Uncommitted capacity / reserve margin | 25% | ISO reports, NERC |
| Large-load tariff & moratorium climate | 20% | Regulatory filings, news |
| Forward power price / congestion | 10% | ISO market data |
| HD on-the-ground read | 10% | Hyperscape Digital |

ERCOTAA-
Texas paused the Batch Zero large-load interconnection study pending a statewide data-center audit, degrading time-to-power (35%) and tariff/moratorium climate (20%). Held to one notch: the pause is finite, ERCOT retains the deepest uncommitted capacity and lowest forward prices on the board, and the audit favors self-generation structures.
