Data center backup generator permits with stated counts and ratings
6 data center projects in our Indiana and Georgia samples whose government records give the number and rating of backup generators. Records dated April 18 to October 18, 2026. A permit lists planned equipment; it is not a purchase order.
Lavender Fields Holdings data center expansion, 402 Royal Road (Google Michigan City)
LaPorte County, Indiana
- Record
- Air permit, Sep 25, 2026. in.gov
- Applicant as named
- Lavender Fields Holdings, LLC

- Draft modification Section A.2: 66 new diesel emergency generators GEN67 to GEN132 at 3,490 kWe (4,680 bhp) each, plus one ancillary generator HUB1 at 167.6 bhp, and 67 new belly tanks of 5,373 gallons each. Known inconsistency: the public notice says 67 critical emergency generators; HUB1 may account for the difference, but no document says so. Existing site: 66 critical emergency generators GEN1 to GEN66 at 2,750 kWe. The modification also proposes removing 2 existing generators and their belly tanks, without naming which. HVO is the secondary fuel; one closed loop air cooling system.
