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 Pennsylvania 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Proposed to under construction, paused, withdrawn or canceled: a planned project and the stage in its latest public record.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 Some stop: Paused, Withdrawn or Canceled.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.

How many in each county?
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.
7 of the 8 counties with mapped data centers rate high or very high for at least one natural hazard. Lightning and winter weather are the most common, with 6 each.
What does power cost in Pennsylvania, and how fast is demand growing?
Businesses pay 12.42¢ per kWh, 7% below the US average, and their power use grew 0.4% from 2019 to 2025.
What do businesses pay for power?
12.42¢ per kWh in 2025, the 23rd highest of 50 states and DC.
Is Pennsylvania'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.
Pennsylvania: 40.14 terawatt-hours (TWh) in 2019, 40.31 TWh in 2025. One TWh is a billion kWh.
Slowly. Business power use grew 0.4% from 2019 to 2025; the US grew 10.5%.
What makes Pennsylvania's power?
About the power mix
This is where the power generated in Pennsylvania came from in 2025: each source's share of what its power plants made, 246 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 58% of the power generated in Pennsylvania in 2025; nuclear made 31%.
Under 1% each: solar, other biomass, other sources, other gases, petroleum and wood.
How much new power is proposed in Pennsylvania?
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 6,671 MW of new power plants for 2026 to 2030; natural gas is the largest source, 4,398 MW.
For scale, Pennsylvania's power plants could deliver 49,201 MW on a summer day in 2025.
Which grid serves Pennsylvania, and what are its water and hazard risks?
PJM runs the grid for nearly all of Pennsylvania's power sales. 1 natural hazard rates very high for Pennsylvania against other states.
Who runs Pennsylvania'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 nearly all of 2025 power sales.
How much water do Pennsylvania'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 32 power plants in Pennsylvania that report their cooling water used up 65.6 billion gallons in 2024, 6% of the 1,097 billion they took in.
Which hazards cost Pennsylvania 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).
Winter weather rates highest for Pennsylvania against other states: very high for the damage it is likely to cause in an average year.
- Very highWinter weather
- Relatively highHeat wave, inland flooding, lightning, cold wave and strong wind
- Relatively moderateHurricane, drought, tornado and ice storm
- Relatively lowEarthquake, landslide, hail and coastal flooding
- Very lowAvalanche and wildfire
Which data center projects are planned in Pennsylvania?

Hatched: the MW expected at full size, not built yet. About the dates
What the dates mean
Not yet operating means the site is still being built or planned. Its computers are not running yet. The year shown is when Epoch AI expects them to start.
First online is the month Epoch AI expects the first computers to switch on. Full size is the month it expects the whole campus to be built. Dates can slip.
Epoch AI, a research group, makes these estimates from satellite photos, permits and company news. They can be off by a fair amount.
About MW
A megawatt (MW) measures how much power a site is built to handle at one time. Think of the size of a pipe, not the water that flows through it over a year.
1,000 MW is one gigawatt (GW).
For an AI campus, this is the power its computers are built for, not cooling or offices.
Are there AI data centers in Pennsylvania?
Yes. Pennsylvania has 2 large AI campuses.
Who runs Pennsylvania's data centers?
About this count
Each building counts once, by the operator named in OpenStreetMap. 39 buildings have no operator named.
Expedient and Flexential tie for the most mapped buildings: 2 each.
