STL1 was announced in 2014 as an $85M, 88,000 sqft multi-tenant data center on 15 acres near Plymouth Industrial Park in Wellston, Missouri, targeted to open in summer 2015. It was never built.
The land is still undeveloped. St Louis County's Land Clearance for Redevelopment Authority holds the parcels and put both Wellston industrial parks out to RFP for logistics and light industrial use in October 2024. Ascent exited data center ownership in 2021 and owns no property in the county.
The specifications below are from the original announcement and were never realized.
