Markley: 2 Tanner Street

Ownership: Markley Group owns the building.
Lot Size: 3 acres

In early 2026, Jeffrey D. Markley, CEO of the Markley Group, purchased the retired 85-megawatt Tanner Street Generating Station and adjacent industrial parcels on Bolt Street for $5.6 million.

Located within Lowell's General Industrial (GI) zoning district, the 2 Tanner Street property encompasses 112,385 square feet (10,440 sqm). Operating through Tanner Street Investco, LLC, Markley secured preliminary municipal approval to subdivide the land into two parcels—spanning 48,677 square feet (4,522 sqm) and 48,113 square feet (4,469 sqm)—and demolish the existing industrial structure.

The acquisition targets a former power generation site that historically served as the city’s largest diesel fuel storage facility, intending to leverage its pre-existing high-capacity grid connectivity to absorb infrastructure overflow from Markley's nearby flagship AI data center campus. However, further development is legally frozen due to a unanimous 10-0 data center moratorium enacted by the Lowell City Council and a parallel environmental justice lawsuit filed by a neighborhood coalition concerning noise and diesel emissions.
