Energy Decision # 36 - Curtailment Clauses Explained: An Impossible Choice for Data Centers

Behind-the-meter load curtailment clauses in data center and large-load interconnection agreements are now a standard condition of faster grid access across PJM, ERCOT, and SPP — and the operators signing these agreements are often doing so without fully understanding the curtailment hierarchy, collateral requirements, or operational design implications buried inside them. This is Energy Decision #36 in the complete C&I energy management series from Tactical Energy Group. 100 decisions. Every one that matters. In this episode, Daniel Burke covers: Why interconnection queues are overwhelmed and why curtailment acceptance has become the price of speed-to-market for large loads. The PJM curtailment hierarchy: Interim NITS, Non-Capacity-Backed Load (NCBL), and traditional load — and why your position in that stack is the most operationally important term in your agreement. Texas SB 6 mandatory curtailment requirements for loads at or above 75 MW interconnected after December 31, 2025. SPP's three-tiered flexible interconnection structure: CHILLS, PALS, and the five-minute full curtailment requirement. The emerging large-load tariff archetype: collateral, minimum bills, contract terms, and exit provisions tracked across recent utility filings. Why the AEP Ohio "instantaneous curtailment synced to local power output" requirement is an engineering mandate buried in a legal document. BTM gas LCOE versus 4-hour BESS as curtailment coverage — and why duration sizing is market- and weather-specific. The FERC Co-Location Technical Conference and why the window for bilateral negotiation may be narrowing. The Bring-Your-Own-Generation (BYOG) fast-track framework and what it changes about the negotiation. Who this is for: hyperscale and colocation data center operators, large greenfield industrial manufacturers, and crypto mining and EV charging facility decision-makers evaluating curtailable interconnection service in exchange for faster grid access. If you are trying to decide whether to accept mandatory curtailment provisions in your interconnection agreement — and how to design operations to survive forced load reduction events without compromising critical workloads — this episode is built for you.
