Summary
The inherited POI (JULIA, 345 kV, 19.0 mi) shows worst-feasible Offtake headroom reaching 250 MW from 2025 under the published ERCOT planning-study envelope after sentinel filtering (28 infeasible markers removed). The binding upgrade class is substation expansion / new bay (12–24 months per EEI 2024 + NERC 2023). No CCN required in Texas for substation modifications. Specific queue depth at JULIA bus not determinable from available data.

28 infeasible sentinel values were nulled from the raw data (values ≥1,000 MW deviating >5× from bus median). Trajectory shows only feasible scenario values across 128 data points.
Next Steps
Commission a powerflow study at JULIA (345 kV) to confirm binding upgrade requirements and energization timeline for 250 MW load
Engage CenterPoint Energy / ERCOT for interconnection pre-application and queue position at JULIA
Validate substation expansion / new bay feasibility with CenterPoint engineering for the 345 kV bus
Monitor ERCOT Regional Transmission Plan (RTP) for planned upgrades near JULIA that may accelerate or delay interconnection
