It's also excluding the 2300 people constructing the datacenter for 1.5 to 2 years. Overall, it sounds like they're trading $15M in tax credits for between 4350 and 5500 person-years of jobs over 20 years. So around $2700 to $3500 per person-year.
2300 seems way high even if you're counting each different person that comes through and most of those won't be working the whole time. They'll come through and do electrical/HVAC/frame construction/etc for a few months then leave. Only a few will be there the whole construction and those will mostly be management and supervisor/contractor roles.
