100 MW solar project in West Texas
Source: NREL
Highest solar irradiance in Texas
PVOUT csi 1835 kWh/kWp
GHI 2048 kWh/m2
DNI 2431 kWh/m2
Located immediately adjacent an ONCOR 138kV electrical substation
Zero-cost grid interconnection
Lowest curtailment risk
ERCOT interconnection screening study found no constraints up to 96 MWac
Legal address: SEC 40 (A16) BLOCK F G&MMB&A, Ward County, Texas
Direct access to both 138kV and 69kV substation and transmission lines
Interconnection screening completed by ERCOT: Cleared for up to 96 MW ac
- STUDY I: SUMMER CASE POST-INTERCONNECTION N-1 ANALYSIS
ERCOT calculated the N-1 transfer capability of the post-interconnection system by modeling incrementally larger generation transfers up to 96 MW (20% greater than the proposed 80 MW output of the project). The study determined that, under N-1 contingency conditions, project had no limits up to 96 MW.

- STUDY II: HIGH-WIND CASE POST-INTERCONNECTION N-1 ANALYSIS
Study II determines the N-1 transfer limit if the nearby wind output is higher than it is assumed to be in the first study. The study determined that, under N-1 contingency conditions, project had no limits up to 96 MW.

- STUDY III: SUB-SYNCHRONOUS INTERACTION STUDY
The interconnection point of the proposed generation project is at low risk for sub-synchronous resonance (SSR) with nearby series capacitors and a full SSR study is deemed not necessary at this point in time under expected grid conditions for the project’s in-service date timeline.

ERCOT completed interconnection screening in June 2023
No transmission line or SSR limitations were found
ERCOT will waive requirement for SSR study
