PJM Interconnection has requested FERC approval to establish a 50MW threshold for behind-the-meter (BTM) generation facilities, responding to FERC's December order for a revamp of its colocation and BTM rules. The new proposal will transition over three years, disallowing netting for new loads exceeding 50MW, while backup generation will not count towards this cap.

Additionally, PJM plans to introduce three tailored transmission services for colocated loads. The proposal aims to support the development of AI-driven data center infrastructure. Concerns have been raised by industry groups that these changes might undermine existing BTM agreements, impacting manufacturers and onsite generation viability.
