Maryland at a glance
The largest footprint in Maryland belongs to TierPoint, LLC, behind 3 tracked facilities. Expedient, LLC, Amazon.com, Inc., and Lumen Technologies, Inc. round out the most active operators in the state. Many of these sites are filed under shell or project names rather than the parent's — our operator column resolves them back to the real corporate parent wherever the chain is documented.
Geographically, the buildout clusters: Baltimore County leads Maryland with 7 facilities and a composite risk score of 10/100. Anne Arundel County and Prince George's County follow. Our county risk score weights project exposure (40%), power demand (30%), water draw (15%), and land footprint (15%); the full breakdown is shown on each county page.
Maryland is not done growing. 9 facilities are in the pipeline — proposed, permitted, or under construction — which is where residents still have a say at zoning hearings and in rate cases. Each pending project is a decision about land, water, electricity prices, and tax revenue that hasn't been finalized.
We also surface the accountability trail: 8 state bills mentioning data centers and 6 recent news items are tracked for Maryland below, pulled from LegiScan and GDELT and refreshed automatically. Legislation is linked to the counties and operators it names; news is classified by community sentiment.
2035 Buildout Outlook
Under the model's moderate-growth scenario (5%/yr annual load growth), PNNL's IM3 model sites about 1 standardized 36 MW campus in Maryland by 2035 — roughly 36 MW of new electricity demand and ~35 M gal/yr of cooling water. For scale, we currently track 27 real data centers in Maryland (2.2 GW of reported power).
- Higher growth136 MW · ~35 M gal/yr cooling water
The model assigns ~100% of these campuses' cooling to evaporative water cooling in Maryland (the rest to mechanical/air cooling), a split it derives from local water stress and wet-bulb temperature.
These are modeled candidate sites, not announced or permitted facilities. PNNL's IM3 model places identical 36 MW unit-campuses at feasible locations under each scenario — it shows where demand could concentrate, never a specific parcel. Figures use a market-gravity weight of 50. How the model works.
