About mapped buildings
Buildings and sites that OpenStreetMap volunteers have tagged as data centers. It counts mapped objects, not an official register, so some data centers are not on it yet.
About large AI campuses
A large data center campus built for AI computing, on Epoch AI's list of AI data centers. “Being built” means Epoch AI lists no computers running there yet.
About business power prices
This is the average price businesses paid for power in New Jersey in 2025. A kilowatt-hour (kWh) is the power a 1,000-watt heater uses in one hour.
“Businesses” is the commercial group in the US Energy Information Administration's figures: offices, stores and most data centers. Some large data centers buy power as industry instead.

What the marks mean
Operating: a building mapped as a data center in OpenStreetMap, in use today. As of Nov 6, 2026.
Proposed to under construction, paused, withdrawn or canceled: a planned project and the stage in its latest public record. As of Nov 7, 2026.
About the stages: a project moves from Proposed to Rezoning filed, Approved, Permitted and Under construction. Some stop: Paused, Withdrawn or Canceled.
AI campus: a large AI campus that is not running yet. As of Nov 7, 2026.
Campuses and projects not placed at their street address are listed, not mapped.
Each kind of mark is counted on its own, and the counts are never added together.

Which natural risks do these counties face?
About the risk ratings
FEMA's National Risk Index scores each county for each natural hazard from 0 to 100, against every county in the US. The score starts from the expected annual loss: the damage a hazard is likely to cause in an average year. It also weighs how many people could be hurt and how well the area can bounce back.
Ratings run from very low to very high.
“Rate high” means relatively high or very high.
All 11 counties with mapped data centers rate high or very high for at least one natural hazard. Strong wind and winter weather are the most common, with 11 each.
What does power cost in New Jersey, and how fast is demand growing?
Businesses pay 16.53¢ per kWh, 24% above the US average, and their power use fell 2.6% from 2019 to 2025.
What do businesses pay for power?
16.53¢ per kWh in 2025, the 12th highest of 50 states and DC.
Is New Jersey's power demand rising?
About business power use
This is the power sold to businesses each year, the commercial group in the US Energy Information Administration's figures. Most data centers are in it, so a fast rise often means new data centers, but offices and stores count too.
New Jersey: 38.01 terawatt-hours (TWh) in 2019, 37.01 TWh in 2025. One TWh is a billion kWh.
No. Business power use fell 2.6% from 2019 to 2025; the US grew 10.5%.
What makes New Jersey's power?
About the power mix
This is where the power generated in New Jersey came from in 2025: each source's share of what its power plants made, 61 terawatt-hours (TWh) in all. Small rooftop solar panels are not counted.
Pumped storage used more power than it made in 2025, so it is left out.
“Other sources” is the agency's catch-all group.
Natural gas made 49% of the power generated in New Jersey in 2025; nuclear made 46%.
Under 1% each: other gases, petroleum, hydro and wind.
How much new power is proposed in New Jersey?
About proposed power plants
These are new power plants that companies have told the US Energy Information Administration they plan to open from 2026 to 2030. Plans can change or be dropped.
Sizes are net summer capacity: the most power a plant can send to the grid on a hot summer day. Each bar's length is its part of all the proposed power.
Companies have proposed 107 MW of new power plants for 2026 to 2030; solar is the largest source, 84 MW.
For scale, New Jersey's power plants could deliver 16,669 MW on a summer day in 2025.
Which grid serves New Jersey, and what are its water and hazard risks?
PJM runs the grid for 99.4% of New Jersey's power sales. 3 natural hazards rate very high for New Jersey against other states.
Who runs New Jersey's power grid?
About the grid
A grid operator, called an ISO or RTO, runs the high-voltage power lines and the power market for a whole region. The share is how much of the state's 2025 power sales were made inside its area.
Where there is none, each utility runs its own part of the grid.
PJM, for 99.4% of 2025 power sales.
How much water do New Jersey's power plants use?
About water taken in and used up
Taken in is the water power plants draw from rivers, lakes, wells or the sea to cool. Used up is the part that does not go back: most of it evaporates.
This is the water power plants use, not the water data centers use.
The 9 power plants in New Jersey that report their cooling water used up 8.4 billion gallons in 2024, 0.9% of the 970 billion they took in.
Which hazards cost New Jersey most?
About expected annual loss
FEMA's National Risk Index estimates each natural hazard's expected annual loss: the damage it is likely to cause in an average year. It rates each state against the other states, from very low to very high.
Hazards with the same rating are in the order of FEMA's score. Because each hazard is compared with other states, one can rate higher here and still cost fewer dollars than another.
Not rated: tsunami (insufficient data) and volcanic activity (not applicable).
Strong wind rates highest for New Jersey against other states: very high for the damage it is likely to cause in an average year.
- Very highStrong wind, coastal flooding and winter weather
- Relatively highInland flooding, ice storm and cold wave
- Relatively moderateHeat wave, hurricane, lightning and tornado
- Relatively lowEarthquake, wildfire and drought
- Very lowHail, landslide and avalanche
