How to read the stack

01

Physical interconnection

Where electricity is synchronized: Eastern, Western, or ERCOT.

02

Market operator

Where organized wholesale and regional transmission rules apply.

03

Balancing authority

Who keeps supply and demand matched continuously.

04

Local utility

Who may serve the meter and run the local interconnection process.

05

Project reality

Available MW, studies, upgrades, commercial terms, and the actual date.

The boundary

Orientation is free. Project certainty is specific.

The Atlas does not represent transmission ownership, available capacity, queue position, deliverability, price, or a legal service-territory determination. Those questions require a named site, a frozen evidence set, and a project-specific investigation.
