Homer City Energy Campus

Homer City Redevelopment / Knighthead · Homer City, Pennsylvania

Not built yet. Every figure below is what it would take and emit at the capacity its owners have announced.

Water — consumed, not returned

Where the water comes from

Municipal potable supply

Cooling

Closed-loop liquid (as proposed)

Basis

Modelled from cooling design — WUE 0.19 L/kWh

Air — what the stacks emit

Where it burns

Behind-the-meter gas turbines + 100% turbines on the site itself

Generation mix

On-site simple/combined-cycle gas, ~100%

Emitted at the fence line

100% of this site's criteria pollution

CO₂e

13,296 kt/yr — climate, not air quality

Who wanted it

Who asked for it

No tenant disclosed; developers cite unnamed hyperclouds

Who approved it

Pennsylvania DEP air permits for seven GE Vernova turbines totalling ~4.5 GW; Indiana County local approvals; sited on an existing but retired transmission interconnection

What it serves

Speculative AI campus — tenants not announced

IT capacity

0 MW running of 3,200 MW announced

Pennsylvania's largest coal plant, demolished in 2023, being replaced by what would be one of the largest gas plants ever built in the US — for a data center campus with no named customer. The clearest instance of speculative gas buildout on AI expectations.

Where it is

40.5200°, -79.1600°

Water and air figures are modelled from disclosed capacity, not measured — site-level error is roughly ±40%. Diesel backup generators are not counted, so on-site figures are floors. Full method.
