Maryland is taking the country’s largest electricity transmission operator to federal court over who should pay for AI’s power appetite. According to Hacker News, the Maryland Office of People’s Counsel (OPC) has filed a complaint with the Federal Energy Regulatory Commission (FERC) against PJM Interconnection, challenging a plan to stick Maryland ratepayers with $2 billion of a $22 billion grid upgrade tied largely to out-of-state data centers.
The math the OPC laid out is brutal. That $2 billion bill translates to roughly $1.6 billion in extra costs for Maryland customers over the next decade. Residential households would shoulder about $823 million (around $345 per customer), commercial users another $146 million (about $673 each), and industrial customers a staggering $629 million (roughly $15,074 per customer).
Why Maryland says the math is broken
PJM covers 13 states plus D.C. and serves 65 million people, about 20% of the U.S. population. Many of those states, including Virginia, Ohio, Pennsylvania, and Illinois, are racing to host hyperscale AI data centers. Maryland’s forecasted load growth is nowhere near those numbers, yet PJM’s cost allocation formula spreads the upgrade tab across the whole footprint.
“PJM’s cost allocation rules are broken,” said Maryland People’s Counsel David S. Lapp in the OPC’s release. “Maryland customers have neither caused the need for these billions in new transmission projects nor will they meaningfully benefit from them.”
The state’s pitch to FERC is straightforward: bill the regions where the towers, lines, and substations actually go up, or send the invoice straight to the tech companies driving the demand. The Trump administration’s “ratepayer protection pledge” was supposed to push hyperscalers in that direction, but enforcement has been spotty.
Why this matters for the AI industry
This is one of the first high-profile attempts by a state regulator to formally challenge how AI’s energy costs are socialized across millions of households. The implications stack up fast:
- Cost discipline arrives at the grid layer. Until now, hyperscalers have largely sidestepped the price tag for the transmission they require. A FERC ruling in Maryland’s favor would force a re-think of how PJM and other ISOs allocate upgrade costs.
- “Extreme uncertainty” on load growth. The OPC argues utilities benefit from these builds even if the projected AI demand never shows up. That’s a direct shot at the speculative capacity forecasts driving the data center boom.
- Permitting headwinds are real. Around 69 jurisdictions have already passed moratoriums on data center projects, and surveys show nearly half of Americans don’t want one near home. A few disputes have turned violent.
What stands out here is the framing. Maryland isn’t anti-AI, it’s anti-subsidy. The state is essentially asking FERC to draw a clear line: if a project is built to serve data centers, the data centers (or their host regions) pay for it.
What to watch next
FERC’s response will set the tone for similar fights brewing across PJM territory and beyond. If Maryland wins, expect:
- Faster moves by other state consumer advocates to file copycat complaints.
- Hyperscalers pushing harder for direct interconnect deals (behind-the-meter nuclear, gas, geothermal) to dodge the regulated grid entirely.
- Renewed scrutiny of the “ratepayer protection pledge” and whether it has any actual teeth.
The AI industry’s growth story has always assumed cheap, abundant power. The bill for that assumption is now landing on people’s electricity statements, and they’re starting to fight back. Full details are available at the original source.
