Sentinel: Project Shirley

Site planned for 2029 and has expansions through 2031
Utility Provider: NIPSCO
Lot Size: 160 acres

Sentinel Data Centers plans four data center buildings and an on-site substation south of East 181st Avenue and east of Clay Street, in unincorporated Eagle Creek Township near Lowell in Lake County, Indiana. A 345 kV transmission line crosses the site. The design uses air cooling with a closed-loop chilled-water system. The project still needs a special exception from the county zoning board and site plan approval.

Site History

  • June 2026: The Lake County Council approves the rezoning 6-0.
  • May 2026: The Lake County Plan Commission sends the rezoning to the council with no recommendation.
  • December 2025: Sentinel presents the project at a plan commission study session.
