Operational · 6A mapped building in OpenStreetMap, a Texas Comptroller program registration, or news reporting the site as running.
Under construction · 0News reporting construction underway at the site.
Planned · 0A TCEQ air permit on file with no mapped building yet, or a project announced in the news. Permits come before buildings, so this is the early-warning state.
Paused · 0News reporting the project on hold.
Inactive · 0News reporting the facility closed or the project cancelled.
Registered, status unknown · 0In a state registry under a program that says nothing about construction (no air permit, no mapped building). Unknown is the answer, not a guess.

How this registry is counted

One row is one campus. OpenStreetMap maps individual buildings, so buildings within 400 meters of each other fold into a single facility; a facility found by two sources within 400 meters of each other is one row that lists both. Coordinates are never altered — a merged row keeps the mapped building’s position.

Status is inferred from what each source states and nothing more: a mapped building or a Texas Comptroller registration means the facility exists; a TCEQ air permit with no building yet means it is permitted, not built; a registry entry under a non-air program says nothing about construction, and the row says so. No source here confirms anything on site.

State and county come from the U.S. Census TIGER/Line county boundaries the facility point falls inside. Every count on this page is computed from the same registry file — nothing is typed in by hand.

Questions

How many data centers are in New Castle County, Delaware?

As of the September 27, 2026 registry snapshot, New Castle County has 6 facilities: 6 operational. Named facilities include COMPUTER SCIENCES CORPORATION, EPA-registered facility, FRS 110017764187, EPA-registered facility, FRS 110017764196, EPA-registered facility, FRS 110040491580. Only facilities recorded in a public source are counted.

Where do these rows come from?

Buildings tagged as data centers in OpenStreetMap, the Texas Comptroller's data-center program registry, and facilities registered as data centers in TCEQ's Central Registry. Each row links the record it came from. County placement uses U.S. Census TIGER/Line boundaries.

What does a data center near a parcel mean for the land?

Two things a landowner cannot see from the surface: demand for nearby land and competition for local water and power. The Geolocity parcel report shows every facility within 25 miles of a specific address alongside the aquifer beneath it and the county's industrial water use. This page is the public record; it is information, not advice.

Do data centers raise or lower nearby home values?

The research does not point to one answer. The National Association of REALTORS® 2026 Data Center Impact Report compared more than 3,200 US counties and surveyed REALTORS® working where data centers operate or are being built: 25% of respondents reported a positive effect on nearby home values and 22% a negative one. NAR Chief Economist Lawrence Yun: “There is no single data center effect. Instead, the story varies significantly depending on the local market.” He added that county-level figures “can't tell us what happens to an individual home next to a facility.”

How do you judge a data center's effect on one specific property?

Property by property, not market by market. Nadia Evangelou, NAR's principal economist and director of real estate research, recommends weighing proximity to the facility, its visibility from the home, local infrastructure, and the specific housing market: “I would recommend looking at it by property.” She also said NAR does not currently track complaint-level data on water or electricity use near specific facilities, and plans to expand its research toward facility-level data. The Geolocity parcel report covers the proximity part from public records: every mapped facility within 25 miles of an address with its distance, alongside the aquifer beneath the parcel and the county's industrial water use. It is information, not an appraisal or advice.
