In brief
Arushi announces that the ERCOT design change Luminary Strategies seeded, letting nodal Provisional Controllable Loads trade curtailment risk for earlier grid power while they await firm upgrades, has received unanimous committee approvals. She traces its path from a September 2025 white paper for the Large Load Working Group, through PGRR134 (filed November 1, 2025) and ERCOT’s proposed PGRR145 (February 2026), to an omnibus now headed to the ERCOT Board and the Public Utility Commission of Texas. The post, written after she taped a segment for the Earthshot Foundation’s GRIDIRON Finale in Washington, DC, credits ERCOT leaders and the 30 companies that filed in support.
