Large Load Integration

Section 9 of the Planning Guide defines the requirements and processes used to facilitate new or modified Large Load Interconnections.

This form must be completed, submitted to ERCOT, and approved prior to the energization of a new Large Load that is not netted with a Generation Resource. Requests to energize a new Large Load netted with a Generation Resource and to increase the amount of load approved to energize at an existing Large Load facility are also covered by other forms in this section.

This form must be completed by the Resource Entity for any Generation Resource with which a Large Load proposes to co-locate. The form may be submitted any time after an LLI number has been assigned to the Large Load project, but ERCOT will not begin its study of the net metering arrangement until the Resource Entity has submitted all information about the arrangement that ERCOT will need for its study, including the TDSP’s completed LLI Study.

This list identifies each stand-alone generation resource registered with ERCOT as of September 1, 2025. In accordance with Section 39.169 of the Public Utility Regulatory Act (PURA), the Resource Entity for any Generation Resource identified on this list that wishes to include a Large Load in a net metering arrangement with that Generation Resource must submit a Notice of Proposed Net Metering Arrangement form and receive Public Utility Commission approval following an ERCOT study before implementing the net metering arrangement. This file was updated on September 19, 2025 to include Energy Storage Resources, consistent with guidance from the Public Utility Commission.
