On June 16, 2026, in Docket No. EL26-4-000, PJM submitted a motion for leave to answer and answer to the June 1, 2026 motion to file supplement to the complaint (Supplement) of Voltus and Mission:data (the Complainants) regarding third-party Curtailment Service Provider access to interval-metered residential demand response data for customers with Advanced Metering Infrastructure (AMI).
