New Generation Resources - Steps to Register
This section offers steps to guide entities through successful integration of a new generation resource into the ERCOT system. "Generation resource" refers to resources interconnected to the ERCOT transmission grid and typically greater than 10 MW. If generation does not meet this criteria, it is considered "distributed generation." (Read Distributed Generation for more information.)
This process starts with the Generation Resource Interconnection or Change Request process as listed in Section 5 of the ERCOT Planning Guides (Generation Interconnection Request Procedure). Please refer to the guide for complete details including contact information, timelines, and requirements. The applicable fees can be found in the ERCOT Fee Schedule.
The Interconnecting Entity (IE) should first submit a Generation Interconnection or Change Request (GINR) application with the following forms:
- The signed Generation Entity Information Sheet
- Resource Asset Registration Forms (.zip) completed with the fields required for the Screening Study, Full Interconnect Study, and the Planning Model. The required fields are marked as "R" for "required" in the Resource Registration Glossary. These forms should be submitted to GINR@ercot.com.
- ERCOT Security Screening Study fee (ERCOT Fee Schedule).
The IE request a Full Interconnection Study (FIS) concurrently with the GINR application, or at any time up to 180 days after the Screening Study results are released. Notice to proceed should be submitted along with the following forms:
- Abbreviated Resource Asset Registration Forms (.zip) filled out using the Screening Study/Full Interconnection Study Guides (.zip). The four forms described in the guide package should be submitted with the appropriate fields filled out as denoted for the FIS phase. These forms should be submitted to GINR@ercot.com Proof of Site Control as described in Section 5.4.9 of the ERCOT Planning Guides
- ERCOT Full Interconnection Study (Stability Modeling) fee (ERCOT Fee Schedule).
- Proof of Site Control as described in Section 5.4.9 of the ERCOT Planning Guides.
The IE and the interconnecting TDSP may execute a Standard Generation Interconnection Agreement (SGIA) within 180 days following the completion of the FIS. Prior to official submission of the RARF, the abbreviated RARF should be completed with the appropriate fields filled out as denoted for the Planning Model phase and submitted to GINR@ercot.com
A key event to plan for is the field energization date when the new point of interconnection with the ERCOT Transmission Grid is approved for initial commissioning. This date represents when the QSE representing the new resource becomes operationally responsible and financially liable for responding to ERCOT operational instructions and settlements, according to protocol.
The entity that will register with ERCOT and be responsible for the Resource is the Resource Entity (RE). This may be the IE, or another entity. Resource Entities bringing on new generation will need to complete these steps:
- Submit the Resource Entity Registration Form (.doc) to ERCOT. The generator must designate a qualified scheduling entity (QSE).
- Submit the Resource Asset Registration Forms (.zip) to ERCOT.
- Complete the design and installation of an ERCOT-polled settlement meter. Refer to the Settlement Metering Operating Guide.
- Establish a data link with the QSE. Refer to the ERCOT Nodal ICCP Handbook.
- Designate a registered load serving entity (LSE) to serve the generation facility during "net load" conditions. ERCOT and the host transmission/distribution service provider will coordinate in creating the electric service identifier (ESI) ID upon receiving the Resource Asset Registration Form.
- Submit PART 1 of ERCOT New Generator Commissioning Checklist (.doc) to the ERCOT account manager. The checklist must be submitted at least seven business days before the initial day the new point of interconnection is planned for first energization.
The RE is encouraged to work with its Qualified Scheduling Entity (QSE) and ERCOT to coordinate planning the first operating day. A change in the operations system is required to establish the operational relationship between QSE and generation resource in ERCOT's energy management system. The RE and QSE are asked to consider the Network Operations Model Change Schedule when establishing this date. The generation resource's QSE representative must perform the following:
- Sign the Resource Entity’s Qualified Scheduling Entity Acknowledgement (.doc) to verify to ERCOT that it is representing the generation resource.
- Using the QSE Qualification and Testing Guide, the QSE must complete required testing, if not currently qualified to represent Resources, before the new point of interconnection and generation starts the commissioning process.
- Coordinate the first operating day with the RE and ERCOT account manager. (Refer to the Network Operations Model Change Schedule.)
- Submit PART 2 of the ERCOT New Generator Commissioning Checklist (.doc) to the ERCOT account manager. The checklist must be submitted at least seven business days before the initial day the new generation is planned for first synchronization.
- When the Resource is ready for full commercial operation and has completed Reactive testing, submit the PART 3 of the ERCOT New Generator Commissioning Checklist (.doc) to request approval from ERCOT to enter full commercial operation.
