PJM Accelerates One‑Time Backstop Auction to Tackle Surging Data‑Center Demand
The operator intends the expedited procurement to fill a looming capacity shortfall while shifting costs onto new large data‑center loads, a step that could reshape who pays for grid reliability.
Overview
- PJM has moved a planned one‑time backstop procurement up to September and structured it as a two‑part process that includes a bilateral contracting phase plus a centralized auction to cover any shortfall from the next Base Residual Auction.
- The grid operator has merged stakeholder talks on the Backstop and its 'connect and manage' rules because it says the two sets of rules are tightly linked and must be decided together.
- PJM asked member states to adopt rules that would allocate the procurement costs to new data‑center loads instead of spreading them to existing residential and commercial customers, but how such targeted cost allocation would work remains unclear to analysts.
- The Department of Energy recently approved PJM’s request to curtail large consumers, including data centers, during a heat wave, and PJM warned that legal challenges or rehearing requests could push final rule certainty into 2027.
- The move follows steep recent capacity‑price spikes, a huge interconnection backlog and federal criticism of PJM governance, and it could affect bills, prompt state policy actions, and trigger litigation over who bears reliability costs.
