Maine's estimated environmental footprint
Summed across Maine's 2 mapped facilities (~10 MW of representative IT draw), these are order-of-magnitude estimates — modelled from each facility's type and US grid/water averages, not metered readings.
Carbon assumes the US grid average of 384 gCO₂/kWh; water uses a 1.8 L/kWh on-site (and 9.4 L/kWh all-in) water-usage-effectiveness reference. Hyperscale campuses on cleaner or dirtier regional grids will vary widely.

Data centers in Maine: frequently asked questions
How many data centers are in Maine?
Maine has 2 mapped data center facilities, across 2 cities including Bangor, Portland. Each is plotted on the interactive map with an estimated daily energy use, electricity cost, and carbon footprint.
Which companies operate data centers in Maine?
Operators on the map include FirstLight, GWI.
Where are most data centers located in Maine?
Maine's mapped data centers are concentrated around Bangor, Portland. Open any facility on the map to see its exact location, operator, and estimated footprint.
Are these Maine energy and carbon figures measured?
No — energy, cost, and carbon are order-of-magnitude estimates derived from each facility's type and the regional electricity grid, not metered readings. They are for awareness and comparison, with data sources cited on the map.
What is the environmental impact of data centers in Maine?
Combined, Maine's 2 mapped facilities draw an estimated 0 TWh of electricity a year — roughly the yearly power of 4,465 homes — emitting about 18,501 metric tons of CO₂ and using on the order of 23 million gallons of cooling water (≈120 million gallons including upstream power generation). These are order-of-magnitude estimates from facility type and US grid/water averages, not metered readings.
