FERC Directs PJM to Reform Tariff for Co-Located Generation and Load
The Federal Energy Regulatory Commission (FERC) has directed PJM Interconnection to reform its tariff for co-located generation and load arrangements by clarifying interconnection procedures and establishing new transmission services by January 20, 2026. The order addresses inconsistencies in PJM's current tariff, requiring revised procedures and rules for Behind-the-Meter Generation by February 18, 2026, to enhance reliability and resource planning.

On December 18, 2025, the Federal Energy Regulatory Commission (FERC) ordered PJM Interconnection to reform its tariff for co-located load arrangements, citing unjust and unreasonable practices. PJM must clarify interconnection procedures and create new transmission services by January 20, 2026, to facilitate connections between data centers and generation facilities.
FERC's order mandates PJM to file revised procedures for interconnection customers by February 17, 2026, and comply with new transmission service options including Interim Network Integration Transmission Service, Firm Contract Demand, and Non-Firm Contract Demand. FERC found that PJM's current tariff lacks clarity on rates and conditions for co-location, resulting in inconsistent treatment of generation interconnection customers. PJM must also revise its Behind-the-Meter Generation (BTMG) rules by February 18, 2026, to ensure reliability and resource adequacy planning.
