200 MW sites are rare and getting rarer. A load this size needs a transmission interconnection, often new lines, and a utility that will commit to a ramp. Buyers at 200 MW increasingly look at three shortcuts: a site with a completed load study, a former plant that keeps its switchyard, or on-site gas that bridges until the grid arrives. Invariant has a 200 MW greenfield with a completed load study and several sites in the 150 to 250 MW band.
Before you start
- 200 MW at the meter is about 154 MW of IT at a PUE of 1.3, roughly 1,280 AI racks at 120 kW, about 92,000 GPUs.
- Expect 230 to 345 kV service, a 10 to 20 acre substation footprint and 100 to 300 acres all in.
- A completed load study for 200 MW is the first document worth paying for. Our Indiana site has one.
- Behind-the-meter gas can bridge the gap. Check turbine supply, air permits and the grid end state.
What 200 MW actually fits
Utilities sell facility load. Tenants buy IT load. At a PUE of 1.3, a 200 MW site leaves about 150 MW for IT. At about 120 kW per NVIDIA GB200 NVL72 rack, that is roughly 1,280 racks, or about 92,310 GPUs. Air-cooled designs at 30 to 50 kW per rack fit more racks and fewer GPUs per MW. Typical buyers at this size are a hyperscaler, an AI lab, a large colocation developer or a sovereign or neocloud buyer.eeNews Europe
| 200 MW site | What to expect |
|---|---|
| IT load at PUE 1.3 | About 150 MW |
| AI racks at 120 kW | About 1,280 |
| Utility service | 230 to 345 kV, often a new switching station and two transmission lines. |
| Land | About 100 to 300 gross acres. |
| Time to power | Under 2 years for sites with studies done or power on site; 4 to 6 years for new 200 MW service in many markets. |
| Documents to ask for | System impact and facilities studies, a construction agreement with collateral, and the energy service agreement or ramp schedule. |
These ranges are Invariant’s working figures from sites we have screened. They are not published standards, and individual utilities and designs land outside them.
The substation alone is a project
ComEd’s 2026 guidelines call for about 8.5 acres for a 345 kV interconnection substation on one line, expandable to about 16.5 acres. PSE&G lists up to 5 acres of customer equipment space at 345 kV. Add the tie-line, access road and stormwater. A 200 MW plan that does not show those acres near the line is a sketch.ComEd via PJMPSE&G
Behind-the-meter as a bridge
On-site gas can deliver 200 MW years before the grid in some markets. It brings its own clocks: firm pipeline capacity, an air permit that may trigger Title V, and turbine or engine supply. GE Vernova reported a gas turbine backlog of about 116 GW. Our Pennsylvania site pairs 200 MW of behind-the-meter gas with a 300 MW grid path, and our Kansas site has a path to 250 MW on gas.Utility DiveUS EPA
200 MW data center sites available now
These sites from Invariant’s current inventory fit a 200 MW requirement, either at that size today or with a phase that covers it. Specs are as marketed by the owner and are checked against utility documents before any introduction.
| Region | Power | Land | Timing |
|---|---|---|---|
| Indiana | 200 MW, load study done | ~80 acres | Substation planned |
| Pennsylvania | 200 MW BTM gas + 300 MW grid | 120 ready acres | Phased |
| Kansas | Path to 250 MW BTM gas | Mineral acreage | Now |
| Wisconsin | 150 MW built, 80 MW now | 130 ready acres | Now |
| Texas metro | 44 MW, +250 MW | ~50 acres, 1M sq ft | Now |
Exact locations, the utility documents behind each MW figure and pricing are shared on a call. We also hold sites that are not listed publicly; owners ask for discretion and a site that is shopped everywhere loses value.
How Invariant finds 200 MW sites
We search from power evidence first and land second. For a 200 MW request we start with stations and services that can carry the load, kill anything already claimed, operating for someone else, contaminated or under a moratorium, and only then look at parcels. Each surviving site is graded A (documented power), B (a named power path with a date) or C (land near capacity), with the one document that would move it up a tier.
Tell us the MW, the states you would consider and the date you need power. We send the 200 MW sites that fit, including ones that are not on this page.

Questions that come up.
How much land does a 200 MW data center need?
Roughly 100 to 300 gross acres, including the 345 kV substation, cooling yards, generators, stormwater and buffers. On-site generation adds more.
How long does it take to get 200 MW for a data center?
With a completed study or power on site, under two years. New service at 200 MW commonly takes 4 to 6 years, driven by transmission work and equipment supply.
Where can I find a 200 MW data center site?
Invariant lists a 200 MW Indiana greenfield with a completed load study, a Pennsylvania site with 200 MW of behind-the-meter gas plus 300 MW grid, a Kansas gas site with a path to 250 MW and a Wisconsin site with 150 MW built. Details are shared on a call.
How does Invariant help find a 200 MW data center site?
Invariant keeps a live inventory of US powered sites, screens each one against utility documents, and matches buyers to sites by MW, state and energization date. Book a call or call (628) 220-8972 with your 200 MW requirement and we send matching sites, including off-market ones.
