Large Load Integration
This section contains guides and documentation to assist Transmission Service Providers (TSPs), Resource Entities (REs), and Interconnecting Large Load Entities (ILLEs) through the interconnection process for new or modified Large Loads to the ERCOT System. Entities wishing to interconnect a load facility of 75 MW or greater should consult Section 9.2.1 of the ERCOT Planning Guide to determine if the request must go through the Large Load Interconnection process. The guides and documents on this page are used as part of the interconnection process.
Questions on the Large Load interconnection process or the materials on this page may be sent to LargeLoadInterconnection@ercot.com.
