PJM Market Monitor Opposes 1.3-GW Gas Plant Deal Between Hull Street, Rockland Capital

Why It Matters

If approved, the transaction would set a precedent for generators to pull capacity out of regional markets for private data‑center use, potentially inflating rates and undermining competition in the PJM grid.

Key Takeaways

• Hull Street plans to acquire 1,267 MW of peaking capacity
• Monitoring Analytics fears capacity will be redirected to data centers
• Withholding could lift PJM energy and capacity prices
• FERC has no explicit policy on capacity removal for data centers

Pulse Analysis

PJM Interconnection, the nation’s largest wholesale electricity market, is grappling with a surge in data‑center construction that tightens supply‑demand balances. As hyperscale operators seek reliable, low‑latency power, they increasingly look to co‑locate with generation assets. This trend has exposed a regulatory blind spot: the Federal Energy Regulatory Commission’s merger review framework does not yet address the risk that owners might pull capacity out of the market to feed private data‑center loads, shifting costs onto all other market participants.

Hull Street Energy’s bid to buy Rockland Capital’s 677‑MW Lee County plant in Illinois and the 590‑MW Tait plant in Ohio exemplifies the emerging conflict. Monitoring Analytics argues that Hull Street, through its Energy Transition & Environmental Management subsidiary, could repurpose these peaking units for an energy‑and‑data‑center campus, effectively withholding capacity from PJM’s capacity market. Such a move would reduce available reserve margins, potentially driving up wholesale prices and granting Hull Street undue market power, a scenario regulators are keen to avoid.

The dispute signals a possible shift in how FERC evaluates future generation acquisitions. If the commission sides with the market monitor, it may require explicit commitments that acquired assets remain in the regional market, or impose new conditions for transactions involving data‑center synergies. This could reshape investment strategies for both power producers and data‑center developers, reinforcing the importance of transparent, market‑aligned capacity planning in an era where digital infrastructure increasingly intertwines with electricity supply.
