50 MW is the line where many utilities start treating a data center as a large load with its own tariff, study fees and collateral. It is also the smallest size many AI tenants will consider for a training build. A good 50 MW site has a study or contract for the power, room for a substation and enough land for a second phase. Invariant has contracted and energized sites from 55 to 85 MW and expandable sites that cover 50 MW in phase one.
Before you start
- 50 MW at the meter is about 38 MW of IT at a PUE of 1.3, roughly 320 AI racks at 120 kW, about 23,000 GPUs.
- AEP Ohio charges $50,000 to study a data center load of 50 to under 100 MW. Expect fees, site-control proof and collateral in most territories.
- Large-load tariffs commonly set minimum bills near 80 to 85% of contract demand for 12 to 15 years.
- Energized or contracted options at 55, 60, 80 and 85 MW are in our inventory now.
What 50 MW actually fits
Utilities sell facility load. Tenants buy IT load. At a PUE of 1.3, a 50 MW site leaves about 38 MW for IT. At about 120 kW per NVIDIA GB200 NVL72 rack, that is roughly 320 racks, or about 23,080 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 an AI training or inference campus, a colocation developer, a hyperscale edge build or a large mining operation.eeNews Europe
| 50 MW site | What to expect |
|---|---|
| IT load at PUE 1.3 | About 38 MW |
| AI racks at 120 kW | About 320 |
| Utility service | Customer substation at 115 to 230 kV, sometimes 345 kV; redundancy usually needs two lines. |
| Land | About 25 to 100 gross acres. |
| Time to power | Now for contracted or energized sites. 2 to 4 years for new service in most US markets. |
| Documents to ask for | A completed load or facilities study, the large-load tariff schedule, a construction or service agreement and any collateral requirement. |
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.
What changes at 50 MW
Utilities have moved fast to set terms for large loads. The Berkeley Lab and Brattle review of 55 large-load tariffs found study requirements, minimum bills and long contract terms spreading through 2025 and 2026. AEP Ohio’s process for loads of 25 MW and above, with study fees stepping up at 50 and 100 MW, is a public example. Read the tariff before you value the site.AEP OhioLawrence Berkeley National Laboratory and The Brattle Group
In Texas, SB 6 rules start at 75 MW, so a 50 MW load in ERCOT sits below the new large-load threshold. That can be a reason to size phase one under 75 MW.
Fast 50 MW
Existing plants and brownfields are the quickest. A former peaker, an industrial plant or a mining campus with a contracted service can move in under a year. A 60 MW gas plant site in New York and a 55 MW contracted brownfield in Oklahoma are examples from our list.
50 MW data center sites available now
These sites from Invariant’s current inventory fit a 50 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 |
|---|---|---|---|
| Oklahoma | 55 MW contracted | ~80 acres | Now |
| New York | 60 MW+ power plant | Plant site | Operating |
| Midwest | 85 MW brownfield | ~20 acres | 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 50 MW sites
We search from power evidence first and land second. For a 50 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 50 MW sites that fit, including ones that are not on this page.

Questions that come up.
How much does it cost to study a 50 MW data center load?
It varies by utility. AEP Ohio charges $50,000 for data center loads of 50 MW to under 100 MW and $10,000 for loads above 25 MW and under 50 MW. Texas set a flat $100,000 study fee for large loads of 75 MW and up under SB 6 rules.AEP OhioUtility Dive
How many acres does a 50 MW data center need?
Roughly 25 to 100 gross acres, including the substation, cooling yards, generators, stormwater and buffers. Multi-story or liquid-cooled designs use less.
Where can I find a 50 MW data center site?
Invariant lists a 55 MW contracted brownfield in Oklahoma, a 60 MW+ power plant site in New York, an 85 MW Midwest brownfield and a Wisconsin site with 80 MW available now. Locations and documents are shared on a call.
How does Invariant help find a 50 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 50 MW requirement and we send matching sites, including off-market ones.
