Large Load Working Group (LLWG)

The Large Load Working Group (LLWG) is non-voting body that reports directly to the ERCOT Technical Advisory Committee (TAC) and provides recommendations to TAC under the scope of its Charter.

LLWG is responsible for developing and recommending policies to facilitate the reliable and efficient integration of Large Loads into the ERCOT system. LLWG’s work covers a range of technical and market issues, including planning, operations, and market-related processes for Large Load interconnection and management. LLWG will also review and provide feedback on associated ERCOT market rules and Revision Requests.

All documents and information from the previous Large Flexible Load Task Force (LFLTF) that was replaced by the LLWG can be found here: Large Flexible Load Task Force.

ERCOT has initiated an extensive stakeholder process to address challenges created by the rapid increase in Large Load interconnection requests. The ultimate goal of the process is a new Large Load interconnection process, referred to as the "Batch Study process.” ERCOT envisions a Batch Study process that will group Large Loads that meet certain stringent requirements into a single study to provide Large Load Customers with study efficiency, consistency, transparency, and certainty while maintaining a system-wide focus on reliability.
