ERCOT Batch Readiness Workshop #2 Summary 05|28|2026
ERCOT outlined a set of milestones with clearly defined responsibilities.
Timeline and responsibilities
- July 10, 2026
- Deadline for ILLEs to submit all required eligibility materials (dynamic models and studies, forms and attestations)
- Last day for ERCOT to review and approve LLIS studies under the legacy process
- ERCOT may review submissions on a rolling basis and provide feedback regarding additional information needed.
- July 24, 2026
- Deadline for TSPs/DSPs to submit complete eligibility packages to ERCOT
- Only administrative corrections or supplemental information required are allowed after July 10th
- No new substantive items (financial security, attestations, or commitments)
- August 7, 2026
- ERCOT notifies TSPs/DSPs of classification and eligibility results
- August 7 – August 31, 2026
- Window if ERCOT has questions about the data, but not to accept new applications. Everything is finalized by August 31st.
- Only provisional answers until PGR145 receives approval from PUCT
- No new applications accepted
- August 31, 2026
- Incomplete projects are excluded from Batch Zero
All outcomes remain provisional until PUCT approval of PGRR145.
Batch zero eligibility requirements by load type
| Eligibility Path | Key ILLE Requirements | Key TSP/DSP Requirements |
| Base Load | Updated dynamic models (if available), acknowledgment of change obligations | Confirmation of energized load status and applicable requirements |
| QSA / IVRT Loads | Similar to Base Load obligations | Similar to Base Load obligations |
| Permian Basin Reliability Plan Loads | Similar to Base Load obligations | Similar to Base Load obligations |
| Advancing Large Loads | Additional requirements: evidence of site control, notarized disclosures, attestation for equipment and NTP | Confirmation of studies, financial security, and interconnection obligations |
| Committed Large Loads | Similar to Advancing Loads | Similar to Advancing Loads |
| Net Metering Loads | Similar to Advancing Loads | Similar to Advancing Loads |
| Studied Loads | Additional requirements: Full technical data package for dynamic and steady-state tests, site control, dynamic models, preliminary LCP. | Confirmation of study requirements and financial security |
| PCLR | Similar to Studied Loads plus Form W | Confirmation of controllable load requirements |
| WLPUN | FIS request submission*, and execution of notarized Form X. *The Generator FIS request must be submitted and deemed complete by July 10. Additionally, the associated generation must not satisfy all requirements of Planning Guide Section 6.9(1) as of July 10. | Confirmation of associated generation requirement and complete FIS request. |
ERCOT noted that Studied Loads, PCLRs, and WLPUN projects generally have the most extensive technical and documentation requirements.
Submission and Validation Toolkit – Drafts updated
- Load Information Form (LIF): Central tool to identify eligibility pathway and track submission completeness
- Attestation templates: Standardized, notarized forms used to certify project readiness, disclosures, and milestones
- TSP/DSP confirmation templates: Used to verify completeness and eligibility before submission to ERCOT
Preparing for Batch Zero
Preparing for Batch Zero requires more than meeting deadlines—it requires complete technical documentation, dynamic modeling, study readiness, and compliance with evolving ERCOT requirements. Zero Emission Grid helps large load customers, developers, and utilities navigate interconnection requirements, evaluate readiness, and reduce submission risk throughout the ERCOT process.
